The invention relates to brewing, in particular apparatuses, assemblies, kits and methods for brewing fresh beverages, such as beer and cider.
Many people enjoy drinking alcoholic beverages, such as beer, in their own homes. Often, consumers will purchase these beverages from shops or, alternatively, order them for delivery to their homes. Both ways of purchasing alcoholic beverages have their drawbacks. When purchasing from a shop, unless the amount purchased is very small, containers for alcoholic beverages are generally large, heavy and difficult to transport. When ordering alcoholic beverages for home delivery to remove this problem, the customer will need to make sure that they are at home when the delivery is made because the containers are generally large, which is restrictive and inflexible. Unlike soft drinks, which can be provided in concentrated form (e.g. fruit squash or cordial), alcoholic beverages require individual packaging, meaning that a large quantity of alcoholic beverage bottles and cans go to landfill. Additionally, alcoholic beverages purchased by either method (shop-bought or home delivery) are often provided in packaging that is environmentally unfriendly (e.g. using plastic to hold cans together) and duty must be paid on the alcoholic beverages, which drastically inflates the purchase price for consumers.
As a result of these problems, and also as a hobby, many people now choose to brew their own beer, or other alcoholic beverages, at home. Consequently, domestic brewing kits have become popular. Usually, in such kits, yeast is added to a mixture of sugary malt extract known as wort (which may be pre-hopped) and water in a fermentation container and the container is sealed. The yeast ferments the sugars in the malt extract to produce ethyl alcohol and release carbon dioxide (CO2). During fermentation, yeast settles in the bottom of the container and can easily become re-suspended in the beverage if the container is shaken, moved or turned, which ruins the beer. Because of this, once the beer has been fermented, it will sometimes be transferred to another vessel for carbonation and/or dispensing, but this normally means that not all of the available beer is used. Alternatively, settled yeast may be captured in another container or a “yeast dump” which can then be removed, but this removal risks spillage of beer, contamination of the beer remaining in the container and depressurisation of the container. Another reason why the beer is generally transferred to another container for dispensing is that the fermentation containers are generally quite tall to allow the separation of sediment, meaning that they are difficult to fit into conventional fridges. This is a problem as beer is more enjoyable when consumed chilled.
As already mentioned, the fermentation process produces CO2. Some of this CO2 remains in the drink to carbonate it but most of it exits the solution and is contained as a gas at the top of the container. Often, gas will be allowed to exit the container via a valve to ensure excess pressure does not build up. Furthermore, sometimes pressure is manually released (a process known as “degassing”). Degassing has the advantage that the flow of liquid from the container can be more predictable when dispensing the beverage than if the pressure within the container is very high, but it can meant that the beer goes flat more quickly. Degassing can also allow oxygen gas (O2) into the liquid which means that the beer will go off more quickly. On the flip side, if the container is not degassed and the pressure remains high, the beer will go flat less quickly but the flow rate during the initial tapping from the container can be unpredictable and fast resulting in an imperfect tapping (e.g. with a large head). In short, it is challenging maintaining well-carbonated beer whilst ensuring a predictable and desirable flow rate.
Achieving a desirable flow rate can also be problematic as more and more tappings take place. As the beer is tapped repeatedly, the pressure within the container gets progressively lower, meaning that the flow rate decreases. This gets worse and worse as more tappings take place until the flow rate becomes too low to ensure a reliable and desirable pour.
There is therefore a need for apparatuses and methods that address these problems.
In accordance with the present invention, there is provided an apparatus for brewing and dispensing a beverage, such as an alcoholic beverage, comprising:
The present invention provides an apparatus for brewing and dispensing a beverage, such as an alcoholic beverage. The beverage could be beer (e.g. ale, lager), but it could be any other suitable alcoholic beverage, such as cider. The apparatus provides a fermentation container, as well as a collector for collecting waste (i.e. yeast) from the fermentation container during the fermentation process. The collector can also be referred to as a “yeast dump”. Advantageously, the collector is attachable to and detachable from (i.e. removably attachable to) the fermentation container via a first outlet which allows fluid communication between the fermentation container and the collector when the collector is attached to the fermentation container but then forms a pressure-tight seal to seal the fermentation container when the collector is not connected to the fermentation container. This means that once the fermentation process has been completed, the collector can be removed from the fermentation container whilst maintaining the pressure within the fermentation container. Maintaining the pressure within the fermentation container means that the beverage in the container will last longer before going flat. Throughout the present application, where the terms “first position” and “second position” are used to describe positions adopted by a component (e.g. the first outlet), the terms “first configuration” and “second configuration” or “first arrangement” and “second arrangement” could equally be used.
The first outlet may be moveable from its first position to its second position by attaching the collector to the fermentation container. Alternatively or additionally, the first outlet may be moveable from its second position to its first position by detaching the collector from the fermentation container. In other words, attaching the collector to the fermentation container automatically establishes the fluid communication between the fermentation container and the collector. Similarly, removing the collector from the fermentation container automatically actuates the pressure-tight seal meaning that the pressure is automatically maintained within the fermentation container. The first outlet may be biased towards its first (i.e. sealed) position by pressure within the fermentation container. This results in a very convenient and user-friendly arrangement that ensures that the beverage does not go flat quickly. Maintaining the pressure in the fermentation container even when the collector has been removed (and whilst it is being removed) has further benefits. Firstly, it prevents the beverage being spilled whilst the collector is being removed. Secondly, it means that the same vessel can be used for fermentation and carbonation. CO2 is released during the fermentation process and, because a pressure-tight seal is maintained even when the collector is removed, enough CO2 is released, captured and retained within the fermentation container (even after the collector has been removed) that the CO2 that is released during primary fermentation is the same CO2 that then carbonates the beverage. This single-vessel fermentation/carbonation is a significant improvement on past apparatuses and avoids the need to inject extra CO2 for carbonation (e.g. through a valve or by using CO2 cartridges) which could risk depressurising the fermentation container or allowing O2 or other contaminants into the container which could spoil the beverage or cause it to go off. The fermentation container may comprise angled or sloping interior walls that encourage waste, such as yeast, to move or slide down the walls of the fermentation container towards the first outlet where it can drop into the collector.
The first outlet may comprise a plug that is moveable from a first position in which the first outlet is in its first position and a second position in which the first outlet is in its second position. The plug may be biased towards its first position by pressure within the fermentation container. The plug may be moveable inwardly towards or into the fermentation container to move the plug from its first position to its second position. The plug may be configured to slide between its first and second positions. The collector may be configured to abut the plug to move it from its first position to its second position. The plug may comprise a body portion having a first surface that is a planar surface (e.g. a flange) that is configured to sealingly engage a corresponding surface (e.g. a planar surface or a flange) on an interior surface of the fermentation container to seal the fermentation container when the plug is in its first position. The plug may further comprise an elongate stem that extends from the planar surface and is in a plane perpendicular to the planar surface of the body portion of the plug, wherein the elongate stem may be configured to slide within a corresponding channel in the fermentation container as the plug moves between its first and second positions. The body portion of the plug may also comprise a second surface on an opposite side of the body portion to the first surface, wherein the second surface is cone-shaped or substantially cone-shaped, in other words it has a central tip and a sloped surface extending outwardly from the central tip to the edge of the body portion. The body portion of the plug may be circular in cross-section. The planar surface (i.e. the first surface) of the body portion may be the proximal surface of the body portion i.e. the surface that faces away from the centre of the fermentation container. The cone-shaped surface (i.e. the second surface) may be the distal surface of the body portion i.e. the surface that faces towards the centre of the fermentation container. This cone shape means that sediment (e.g. yeast) will slide off the top of the body portion of the plug to the bottom of the fermentation container from where it can drop into the collector through the first outlet. This plug arrangement provides a user-friendly and reliable means for attaching and detaching the collector whilst maintaining the pressure within the fermentation container. There are minimal moving parts meaning that maintenance is simple and the mechanism does not wear, and the combination of the surfaces on the plug and the interior of the fermentation container provides a reliable seal. Of course, the planar surface of the plug could equally sealingly engage a surface, such as a planar surface or a flange, on an exterior surface of the fermentation container to provide the pressure-tight seal, or other suitable mechanisms could be used (e.g. snap-fit, interference fit). With the combination of the elongate stem and the cone-shaped body portion, the plug can take the form of an “umbrella” shape.
The apparatus may further comprise a tap assembly that is attachable to the fermentation container for dispensing a beverage from the fermentation container. The fermentation container may comprise a second outlet and the tap assembly may be attachable to the fermentation container at the second outlet to allow fluid communication between the fermentation container and the tap assembly to dispense a beverage from the fermentation container. The collector may be configured to enclose the tap assembly when the collector is attached to the fermentation container and to expose the tap assembly when the collector is not attached to the fermentation container. The collector may be configured to prevent actuation of the tap assembly when the collector is attached to the fermentation container and to allow activation of the tap assembly when the collector is not attached to the fermentation container. The collector may be configured to abut the tap assembly when the collector is attached to the fermentation container. In other words, by enclosing the tap assembly or otherwise restricting access to the tap assembly, the collector can prevent accidental actuation of the tap assembly during the fermentation process.
In another embodiment, the tap assembly may be attachable to the fermentation container at the first outlet when the collector is not attached to the fermentation container to allow fluid communication between the fermentation container and the tap assembly to dispense a beverage from the fermentation container. In other words, the tap assembly may be attachable to the fermentation container in the same place as the collector is attachable to the fermentation container. The first outlet may be moveable from its first position to its second position by attaching the tap assembly to the fermentation container. The first outlet may be moveable from its second position to its first position by detaching the tap assembly from the fermentation container. In other words, the tap assembly can move the first outlet between its first and second positions in the same way that the collector does so. What this means is that the tap assembly and the collector can be interchangeably attached to and detached from the fermentation container, and the fact that the pressure-tight seal is automatically maintained when neither the tap assembly nor the collector is attached to the fermentation container means that pressure can be maintained within the fermentation container and contamination can be prevented.
In any of the above embodiments, the tap assembly may be attachable to the fermentation container by a resilient fit, a snap-fit or an interference fit. The tap assembly may comprise a handle that is attachable to and detachable from the tap assembly to facilitate actuation of the tap assembly. The handle may be attachable to the tap assembly magnetically. The tap assembly may be actuatable by rotating the handle about a pivot of the tap assembly. The tap assembly may be detachable from the fermentation container (e.g. for cleaning or maintenance).
The tap assembly may comprise a hood for preventing sediment (e.g. yeast) from blocking the tap assembly. The hood may comprise a barrier portion that is configured and positioned to protect the tap assembly and an angled or sloped surface that is configured to guide sediment (e.g. yeast) away from the tap assembly (i.e. the sediment slides away towards the collector under the force of gravity). In this way, the hood prevents the beverage from being spoilt and prevents the tap assembly from becoming blocked, thereby ensuring reliable dispensing of the beverage.
The fermentation container may further comprise a safety valve for allowing gas to exit the fermentation container during fermentation. The fermentation container may comprise at least one safety valve or a plurality of safety valves. The tap assembly and the safety valve may be located at diagonally opposite corners of the fermentation container when the tap assembly is attached to the fermentation container. In other words, the tap assembly (or whichever outlet or other connection point the tap assembly is attached to) and the safety valve are located on opposite sides (or substantially opposite side) of the fermentation container in two dimensions. For example, if the tap assembly is located at the front bottom corner of the fermentation container then the safety valve is located at the rear top corner of the fermentation container. Equally, if the tap assembly is located at the rear bottom corner of the fermentation container then the safety valve is located at the front top corner of the fermentation container. The skilled person will understand other similar opposing combinations. This has the advantage that no matter whether the apparatus is upright or lying on its side, beverage can be dispensed through the tap assembly and degassing can occur through the safety valve because the tap assembly is located at the bottom and the safety valve is located at the top regardless of whether the apparatus is upright or on its side. This offers significant benefits in terms of flexibility of storage and use.
In particular, this aspect of the invention means that the apparatus is well-configured to be positioned vertically during fermentation (i.e. with the safety valve at the top expelling gas upwards and the collector at the bottom collecting downward waste) and positioned horizontally during carbonation and dispensing (i.e. with the tap assembly dispensing beverage downwards). This is advantageous because it means that the apparatus is more manoeuvrable into a range of locations for carbonation and dispensing. For example, the apparatus can be positioned upright for fermentation, which is desirable because the fermentation process benefits from the effect of gravity (e.g. encouraging waste such as yeast to move downwards towards and into the collector), then the collector can be removed and the apparatus can be placed on a normal domestic refrigerator shelf for carbonation and dispensing, which is desirable because carbonation occurs more quickly in a refrigerator and the beverage is more enjoyable when cold. It would be more difficult to place the apparatus on a refrigerator shelf if it remained vertical at all times. This means that fermentation, carbonation and dispensing can all be done using the same fermentation container.
The fermentation container may have a first axis and a second axis that is perpendicular to the first axis, wherein the fermentation container may be configured to be oriented with the first axis being vertical and the second axis being horizontal during fermentation, and wherein the fermentation container may be configured to be oriented with the first axis being horizontal and the second axis being vertical for a fermented beverage to be dispensed via the tap assembly. The fermentation container may be longer along the first axis than along the second axis. These dimensions further enhance the capability for the apparatus to be placed on a domestic refrigerator shelf for carbonation and dispensing, and the capability of the fermentation container to be oriented in these directions for fermentation, carbonation and dispensing arises from the structural features of the apparatuses described herein.
The fermentation container may further comprise a dosing valve for injecting brewing ingredients, such as fresh hops, finings, additional yeast (e.g. for secondary fermentation) and flavourings (e.g. natural flavourings) into the fermentation container whilst maintaining the pressure within the fermentation container. The dosing valve may be the same feature as the safety valve. The fermentation container may be configured to use the CO2 produced during primary fermentation to carbonate the beverage.
There is also provided a tap assembly for a fermentation apparatus comprising:
As described previously, it is challenging maintaining a high pressure for well-carbonated beer whilst ensuring a predictable and desirable flow rate. The moveable component of the tap assembly can be moved to a plurality of positions covering the aperture to differing degrees (preferably continuously to allow an infinite number of positions, although discreet positions could alternatively be provided e.g. using a ratchet mechanism) to control the flow rate through the aperture. The provision of a tap assembly having a moveable component that allows a user to control the portion of the aperture that is left open for fluid to pass therethrough means that the user can easily control the flow rate depending on how high the pressure is within the fermentation container. If the pressure is high (e.g. when few tappings have taken place), a small aperture size can be chosen so that the flow rate is restrained. If the pressure is lower (e.g. after more tappings), a larger aperture can be chosen to provide a sufficient flow. This means that the pressure within the fermentation container can be kept high to begin with, resulting in well-carbonated beverage for longer.
The tap assembly may further comprise a channel in which the moveable component may be configured to slide (e.g. translate, or move in a linear direction) when moving between its first position and its second positions. The moveable component may be configured to prevent passage of fluid through the aperture when in its first position and to allow passage of fluid through the aperture when in its second positions. The passage of fluid through the aperture may be controllable by controlling the portion of the aperture that is blocked by the moveable component. The tap assembly may further comprise a biasing means configured to bias the moveable component towards its first position. The biasing means may be a spring. Biasing the moveable component in this way ensures that beverage does not leak accidentally.
The actuator may be configured to abut the moveable component to move the moveable component between its first and second positions. The actuator may comprise an arm, and the tap assembly may further comprise a pivot about which the actuator is configured to rotate. The tap assembly may further comprise a handle that may be attachable to the actuator. Such a rotational handle is compact and easy to use. The handle may be attachable to the tap assembly magnetically, which is a secure and convenient way of attaching and detaching the handle from the actuator.
The tap assembly may comprise a hood for preventing sediment (e.g. yeast) from blocking the tap assembly. The hood may comprise a barrier portion that is configured and positioned to protect the aperture and an angled or sloped surface connected to the barrier portion that is configured to guide sediment (e.g. yeast) away from the tap assembly (i.e. the sediment slides away towards the collector under the force of gravity). In this way, the hood prevent the beverage from being spoilt and prevents the tap assembly from becoming blocked, thereby ensuring reliable dispensing of the beverage.
The apparatus described above may comprise the tap assemblies described herein.
There is also provided a method comprising:
The apparatus may be rotated by approximately 90 degrees between the steps of fermenting the beverage and carbonating the beverage.
The method may further comprise providing a tap assembly in fluid combination with the fermentation container, and dispensing a beverage from the fermentation container via the tap assembly. The apparatus may be rotated by approximately 90 degrees between the steps of fermenting the beverage and dispensing the beverage. Additionally or alternatively, the apparatus may remain in the same orientation during the steps of carbonating the alcoholic beverage and dispensing the alcoholic beverage.
The apparatus may be placed in a refrigerator before the step of carbonating the beverage. Additionally or alternatively, the apparatus may be placed in a refrigerator before the step of dispensing the beverage.
The collector may be detached from the fermentation container before the step of carbonating the beverage. Additionally or alternatively, the collector may be detached from the fermentation container before the step of dispensing the beverage. Additionally or alternatively, the collector may be detached from the fermentation container before the apparatus is rotated by approximately 90 degrees.
The method may be used with the apparatuses described herein.
There is also provided a package containing ingredients for brewing an alcoholic beverage, wherein the package is shaped and sized so that it can fit through a standard domestic letterbox.
The package may contain ingredients for brewing beer, such as yeast, syrup and steriliser. The package may contain some or all of these. The package may be substantially cuboidal in shape. A maximum diameter of the package along a first axis may be no more than 50 mm (or approximately 50 mm) and a maximum diameter of the package along a second axis that is perpendicular or substantially perpendicular to the first axis may be no more than 350 mm (or approximately 350 mm). A maximum diameter of the package along a first axis may be no more than 50 mm (or approximately 50 mm) and a maximum diameter of the package along a second axis that is perpendicular or substantially perpendicular to the first axis may be no more than 350 mm (or approximately 350 mm). A maximum diameter of the package along a first axis may be no more than 40 mm (or approximately 40 mm) and a maximum diameter of the package along a second axis that is perpendicular or substantially perpendicular to the first axis may be no more than 300 mm (or approximately 300 mm). A maximum diameter of the package along a first axis may be no more than 35 mm (or approximately 35 mm) and a maximum diameter of the package along a second axis that is perpendicular or substantially perpendicular to the first axis may be no more than 250 mm (or approximately 250 mm). A maximum diameter of the package along a first axis may be no more than 30 mm (or approximately 30 mm) and a maximum diameter of the package along a second axis that is perpendicular or substantially perpendicular to the first axis may be no more than 250 mm (or approximately 250 mm). A maximum diameter of the package along a first axis may be no more than 25 mm (or approximately 25 mm) and a maximum diameter of the package along a second axis that is perpendicular or substantially perpendicular to the first axis may be no more than 250 mm (or approximately 250 mm). In real terms, thinking about the height and width of a standard letterbox, “height” may be the maximum diameter along the first axis and “width” may be the maximum diameter along the second axis that is perpendicular to the first axis. It will be understood that the package will also have a “length” i.e. a diameter along a third axis that is perpendicular or substantially perpendicular to both the first and second axes. However, the skilled person will understand that as long as at least two of these three maximum diameters are sufficiently small (height and width in the definitions above, and when envisaging a real-life letterbox), then the package will fit through a standard letterbox. The diameter along the third axis (i.e. the length) may be greater than the maximum diameters along the first and second axes (i.e. the height and width), although clearly this does not necessarily have to be the case.
The package of the invention is intended to contain refill ingredients and steriliser for the apparatus of the invention. The package is compact and intended for delivery through a standard domestic letterbox. This means that the consumer does not need to transport the beverage home from a shop and also does not need to be present to accept a home delivery, which would conventionally have been too large to fit through a letterbox. The package of the invention also has additional benefits for the consumer because duty would not need to be paid on the package, reducing cost. The package of the invention also has significant environmental benefits because it reduces the packaging needed for enjoyment of beverages, such as beer, at home. For example, a considerable amount of plastic is conventionally used in packaging for beverages (e.g. plastic holding cans together).
There is also provided a kit comprising the apparatus of the invention and the package of the invention.
In accordance with the present invention, there is also provided a collector for collecting waste from a fermentation container, the collector comprising;
The collector of the invention advantageously has an inlet that can be moved between a first configuration in which the inlet is sealed and waste is prevented from entering the chamber, and a second configuration in which the inlet is unsealed and waste is allowed to enter the chamber. In this way, once the waste has been gathered in the collector during the fermentation process, the collector can be sealed off to prevent any waste (e.g. waste liquid and/or sediment) from spilling from the collector.
The inlet may comprise a stopper that is movable between a first position in which the inlet is in its first configuration and a second position in which the inlet is in its second configuration. The stopper may be movable in a direction inwardly towards the centre of the chamber when moving from its first position to its second position and the stopper may be movable in a direction outwardly away from the centre of the chamber when moving from its second position to its first position. This provides a simple and convenient arrangement for sealing and unsealing the collector at the inlet.
The stopper may be biased towards its first (i.e. sealed) position by pressure within the collector. The stopper may also comprise a float that is configured to float on waste collected within the chamber. This is advantageous because it allows the stopper to float on the waste (e.g. waste liquid and/or sediment) that has gathered in the collector during the fermentation process and rise to seal the inlet automatically. The float may be substantially hollow. The stopper may be configured to gradually release pressure from the collector to prevent the collector from becoming overpressurised if carbonated beverage remains in the collector. This can be achieved by shaping the stopper to gradually release pressure or by using the surface properties (e.g. materials) of the stopper, for example.
The stopper may further comprise a stem extending from the float at least partially through the inlet. The stem may be shaped to permit fluid flow therethrough, such as a cross-shaped cross-sectional shape, a Y-shaped cross-sectional shape or a cylindrical shape. This shape means that the stopper can permit fluid flow through the inlet when the float is not sealing the inlet.
There is also provided an apparatus comprising:
This apparatus provides an advantageous arrangement in which attaching the fermentation container and the collector automatically results in the collector inlet moving from its first configuration to its second configuration to permit waste from the fermentation container to enter the collector chamber. Similarly, detaching the fermentation container and the collector automatically results in the collector inlet moving from its second configuration to its first configuration to seal the collector chamber and prevent spillage of waste from the collector.
The outlet may be moveable between:
Advantageously, the collector is attachable to and detachable from (i.e. removably attachable to) the fermentation container via a first outlet which allows fluid communication between the fermentation container and the collector when the collector is attached to the fermentation container but then forms a pressure-tight seal to seal the fermentation container when the collector is not connected to the fermentation container. This means that once the fermentation process has been completed, the collector can be removed from the fermentation container whilst maintaining the pressure within the fermentation container. Maintaining the pressure within the fermentation container means that the beverage in the container will last longer before going flat.
The outlet may comprise a plug that is configured to abut the stopper to move the stopper between its first and second positions. This abutment also moves the plug between its first and second positions. In other words, when the fermentation container and the collector are attached, the plug of the fermentation container and the stopper of the collector abut each other meaning that both the plug and the stopper automatically move to their second positions to permit waste from the fermentation container to pass through the fermentation container outlet and the collector inlet to gather in the collector. Similarly, when the fermentation container and the collector are not attached (i.e. detached), the plug of the fermentation container and the stopper of the collector no longer abut each other meaning that both the plug and the stopper automatically move to their first positions to seal the fermentation container (to maintain pressure and seal the collector (to prevent spillage of waste). This automatic movement of the plug and stopper is highly advantageous and reduced the amount of user input required. The plug and the stopper may be biased towards their first and second positions by pressure within the fermentation container and the collector, respectively.
The plug may comprise an abutment portion that is shaped to permit fluid flow therethrough, such as a cross-shaped cross-sectional shape, a Y-shaped cross-sectional shape or a cylindrical shape and that is configured to abut the stopper. Having an abutment portion of the plug and a stem of the stopper that are the same shape improves the engagement or abutment between the plug and the stopper. Moreover, the plug and stopper shapes described herein permit fluid flow through the fermentation container outlet and the collector inlet when the outlet and inlet are not sealed (i.e. in their second configurations).
In accordance with the present invention, there is also provided a tap assembly for a fermentation apparatus comprising:
The movable component may be movable to a plurality of second positions. The first conduit may be longer than the second conduit. The first conduit may comprise a tube configured to allow passage of fluid therethrough.
The tap assembly may further comprise an actuator for moving the movable component and a handle coupled to the actuator. The handle may be configured to be moved a first distance to permit passage of fluid through the first conduit only and a second distance to allow passage of fluid through the first and second conduits. This arrangement, along with the fact that the first and second conduits apply different resistances to the fluid being tapped, allows for optimal frothing and fluid flow throughout the entire tapping procedure, even as the pressure within the fermentation container decreases. For example, where the first conduit applies a greater resistance to fluid flowing through it than the second conduit, the handle can be moved a first distance whilst fluid passes through the first conduit only to ensure that the fluid flow is not too fast at high pressure and that the beverage (e.g. beer) is not too frothy. Once the pressure within the fermentation container has reduced by a certain amount, the handle can be moved a second distance and fluid flows through both the first and second conduits. This ensures sufficient fluid flow even at low pressures within the fermentation container because the second conduit applies a lower resistance to the fluid being tapped than the first conduit.
The movable component may completely block the second conduit when the movable component is in its first position, and the movable component may allow passage of fluid through the second conduit when the movable component is in one of its second positions. The passage of fluid through the second conduit may be controllable by controlling the portion of the second conduit that is blocked by the moveable component.
As described previously, it is challenging maintaining a high pressure for well-carbonated beer whilst ensuring a predictable and desirable flow rate. The moveable component of the tap assembly can be moved to a plurality of positions covering the second conduit to differing degrees (preferably continuously to allow an infinite number of positions, although discreet positions could alternatively be provided e.g. using a ratchet mechanism) to control the flow rate through the second conduit. The provision of a tap assembly having a moveable component that allows a user to control the portion of the second conduit that is left open for fluid to pass therethrough means that the user can easily control the flow rate depending on how high the pressure is within the fermentation container. If the pressure is high (e.g. when few tappings have taken place), a small second conduit size can be chosen so that the flow rate is restrained. If the pressure is lower (e.g. after more tappings), a larger second conduit can be chosen to provide a sufficient flow. This means that the pressure within the fermentation container can be kept high to begin with, resulting in well-carbonated beverage for longer.
The handle may be attachable to the tap assembly magnetically.
In accordance with the present invention, there is also provided a tap assembly comprising:
The tap assembly of the invention serves two key purposes. Firstly, it ensures that the user properly attaches the tap to the tap holder before tapping takes place. Secondly, it ensures that the tap is not accidentally detached from the tap holder once the tap has been attached. Both of these results are important in ensuring proper tapping and preventing spillage or danger from the tap becoming detached accidentally.
The tap may be rotatable relative to the tap holder in a first direction to move the tap from its unlocked position to its locked position and in a second direction to move the tap from its locked position to its unlocked position. The tap may be prevented from moving further in the first direction when the tap is in its locked position. This prevents damage that could result from a user attempting to attach the tap to the tap holder using excessive force and also indicates to the user when the tap have been attached properly. The tap may comprise a protrusion extending from the tap and the tap holder may comprise a channel, wherein the protrusion may be configured to translate within the channel as the tap moves between its locked position and its unlocked position, and wherein the channel may be configured to retain the protrusion when the tap is in its locked position. In other words, to attach the tap to the tap holder, the user must position the tap with the protrusion adjacent to the channel of the tap holder and then rotate the tap so that the protrusion moves along the channel (i.e. rotating the tap from its unlocked position to its locked position). The channel of the tap holder then serves the additional purpose of preventing detachment of the tap from the tap holder by retaining the protrusion within the channel. This prevents the tap from shooting from the tap holder at pressure even if the user incorrectly installs the tap. The tap holder may comprise a detent that is configured to abut the protrusion when the tap is in its locked position to prevent the tap from moving further in the first direction when the tap is in its locked position. This prevents damage that could result from a user attempting to attach the tap to the tap holder using excessive force and also indicates to the user when the tap have been attached properly.
The tap assembly may further comprise a secondary retention means configured to retain the tap in its locked position, wherein the secondary retention means may be configured to be engaged automatically when the tap is moved to its locked position, and wherein the secondary retention means may be configured to be disengaged by moving the tap axially towards the tap holder so that the tap can be moved to its unlocked position. The secondary retention means may be a resilient clip, a pair of resilient clips or a plurality of resilient clips and may provide an additional layer of safety by preventing accidental removal of the tap from the tap holder. When it is desired to remove the tap from the tap holder, the user pushes the tap axially into the tap holder to disengage the secondary retention feature and then the tap may be rotated from its locked position to its unlocked position to permit removal of the tap from the tap holder. The requirement to move the tap first axially and then rotationally to detach the tap from the tap holder further enhances the safety of the arrangement because this is a deliberate motion that would not occur accidentally.
The features of the tap assembly may be combined with any of the features of the other tap assemblies described herein.
In accordance with the present invention, there is also provided a valve for a fermentation container comprising:
The provision of a valve where the resistance of the valve can be varied is highly advantageous as this allows for the pressure within the fermentation container to be controlled and varied. This is important as it means that a wide variety of beverages (e.g. lagers, ciders, bitters, stouts, ales) can be fermented at their optimal pressure, resulting in the optimal carbonation. For example, a lager would be brewed at high pressure for a greater degree of carbonation whereas a stout would be brewed at low pressure for little or no carbonation.
The valve may further comprise a spring arranged between the actuator and the stopper, wherein the actuator may be configured to apply variable force to the spring to variably compress the spring, and wherein the spring may be configured to apply variable force to the stopper to vary the resistance of the valve. In other words, the resistance of the valve (and therefore the pressure within the fermentation container) can be controlled and varied by varying the compression of the spring. The spring may be a compression spring, a helical spring, a leaf spring or any other suitable spring or biasing means.
The actuator may be rotatable, wherein rotating the actuator may vary the pressure applied to the stopper. Rotation of the actuator is a convenient and compact way for a user to vary the pressure within the fermentation container.
The actuator may be movable to vary the force applied to the stopper by means of a screw thread. The actuator may comprise a screw thread and the valve body may comprise a protrusion about which the screw thread is configured to translate as the actuator is rotated. This provides a predictable and reliable movement of the actuator and, consequently, a predictable and reliable variation of the resistance of the valve and therefore the pressure within the fermentation container.
The valve may be used as a safety valve with any of the fermentation containers or fermentation apparatuses described herein. Alternatively or additionally, the valve may be employed in addition to a safety valve.
In accordance with the present invention, there is also provided a fermentation apparatus comprising:
The present invention advantageously provides a convenient and elegant way of preventing the cap from being detached from the fermentation container accidentally during fermentation by using the handle as a part of the locking mechanism. This removes the need for additional locking features which simplifies the design.
The handle may be prevented from moving from its first position to its second position until the cap is attached to the fermentation container. This way, the user cannot misuse the locking mechanism, which would risk damaging the apparatus.
At least one of the cap and the fermentation apparatus may comprise an indicator to indicate when the cap has been attached to the fermentation container. This assists the user in alerting him/her when the handle can be moved to its second position to lock the cap. The cap and the fermentation container may comprise corresponding screw threads for attaching the cap to the fermentation container wherein the cap and the fermentation container may each comprise corresponding detents that are configured to abut each other when the cap has been attached to the fermentation container. This is a convenient and effective way of indicating to the user that the cap has been properly attached to the fermentation container.
The handle may be movable from its first position to its second position in a first direction but may be prevented from moving in a second direction that is opposed to the first direction when the cap has been attached to the fermentation container. This prevents the user from misusing the handle or improperly locking the cap to the fermentation container.
The fermentation container may comprise an abutment that is configured to abut the handle if removal of the cap is attempted when the handle is in its second position. In other words, once the handle is in its second position, if the user attempts to remove the cap, the handle of the cap abuts against the abutment of the fermentation container to prevent this from happening. This is a neat and effective way of preventing accidental removal of the cap using the existing handle of the cap.
The fermentation apparatus may further comprise a collector (i.e. a yeast dump as described previously) that is attachable to the fermentation container to collect waste from the fermentation container, wherein the collector may comprise a projection that is configured to engage the handle when the handle is in its second position to prevent the handle from moving to its first position. In other words, the collector is shaped (via the projection) to retain the handle in its second position whilst the collector is being attached to or detached from the fermentation container so that accidental removal of the cap is prevented whilst this process is taking place.
The cap and handle may be used with any of the fermentation containers or fermentation apparatuses described herein.
The present invention will now be described with reference to the accompanying drawings, in which:
Before use, the fermentation container 202 is sterilised. During fermentation, the fermentation ingredients (e.g. yeast, a syrup containing pre-hopped malt extract and water) are poured into the fermentation container 202 and the fermentation container 202 is sealed. The mixture is left to ferment in the fermentation container 202 with the fermentation container vertically upright (i.e. in the orientation shown in
In
Once fermentation is complete, the collector 206 is removed from the fermentation container 202. During fermentation, all of the waste yeast has settled in the collector 206 and therefore the beverage in the fermentation container 202 is free of sediment.
Once fermentation is complete, the collector 206 has been removed and the handle 212 has been attached, the apparatus 200 is rotated 90 degrees onto its side (i.e. in the orientation shown in
The tap assembly 204 and the safety valve 210 are located at diagonally opposite corners of the fermentation container 202 when the tap assembly 204 is attached to the fermentation container. In other words, the tap assembly 204 and the safety valve 210 are located on opposite sides of the fermentation container in two dimensions. For example, if the tap assembly 204 is located at the front bottom corner of the fermentation container 202 then the safety valve 210 is located at the rear top corner of the fermentation container 202. Equally, if the tap assembly 204 is located at the rear bottom corner of the fermentation container 202 then the safety valve 210 is located at the front top corner of the fermentation container 202. The skilled person will understand other similar opposing combinations. This has the advantage that no matter whether the apparatus is upright or lying on its side, beverage can be dispensed through the tap assembly and degassing can occur through the safety valve because the tap assembly is located at the bottom and the safety valve is located at the top regardless of whether the apparatus is upright or on its side. This offers significant benefits in terms of flexibility of storage and use.
In the horizontal position shown in
As shown in
As shown in
The plug 216 moves inwardly by sliding into the fermentation container 202 when the plug 216 is moved from its first position to its second position. In particular, when the collector 206 is pushed onto the fermentation container 202, it abuts the plug 216 to move it from its first position to its second position to open the first outlet 208 and establish fluid communication between the fermentation container 202 and the collector 206. The plug is biased towards its first position by pressure within the fermentation container.
The plug 216 comprises a body portion 217 having a first surface 218 that is a planar surface that is configured to sealingly engage a corresponding surface 220 on an interior surface of the fermentation container 202 to seal the fermentation container 202 when the plug 216 is in its first position. The body portion 217 of the plug also comprises a second surface 219 that opposes (i.e. is on the opposite face of) the first surface 218. The second surface 219 is cone-shaped (or substantially cone-shaped) with a central tip and a sloped surface extending from the central tip to the edge of the body portion 217. This cone shape means that sediment (e.g. yeast) will slide off the top of the body portion 217 of the plug 216 to the bottom of the fermentation container 202 from where it can drop into the collector 206 through the first outlet 208. The planar surface 218 (i.e. the first surface) of the body portion 217 is the proximal surface of the body portion 217 i.e. the surface that faces away from the centre of the fermentation container 202. The cone-shaped surface 219 (i.e. the second surface) is the distal surface of the body portion 217 i.e. the surface that faces towards the centre of the fermentation container 202. The body portion 217 of the plug 218 is circular or substantially circular in cross-section. The plug 216 also comprises an elongate stem 222 that extends from the planar surface 218 and is in a plane perpendicular to the planar surface 218 of the body portion 217. The elongate stem 222 is configured to slide within a corresponding channel in the fermentation container 202 as the plug 216 moves between its first and second positions. This plug arrangement provides a user-friendly and reliable means for attaching and detaching the collector 206 whilst maintaining the pressure within the fermentation container. There are minimal moving parts meaning that maintenance is simple and the mechanism does not wear, and the combination of the surfaces on the plug and the interior of the fermentation container provides a reliable seal. In the embodiment shown in the Figures, with the combination of the elongate stem 222 and the cone-shaped body portion 217, the plug 216 can take the form of an “umbrella” shape, although this is not essential.
As shown in
The tap assembly 204 is attachable to the fermentation container 202 by a resilient fit, a snap-fit or an interference fit. The handle 212 is attachable to the tap assembly magnetically, meaning that it can be easily but securely attached and detached.
The tap assembly comprises a hood 213 for preventing sediment (e.g. yeast) from blocking the tap assembly 213. It can be seen that the hood 213 comprises a barrier portion 211 configured to block sediment from dropping into the tap assembly 213 and an angled or sloped surface 215 extending from the barrier portion 211 that is configured to guide sediment (e.g. yeast) away from the tap assembly 204 (i.e. the sediment slides away towards the bottom of the fermentation container 202 and the collector 206 under the force of gravity). In this way, the hood 213 prevents the beverage from being spoilt and prevents the tap assembly 204 from becoming blocked, thereby ensuring reliable dispensing of the beverage.
There is also an actuator 228, which takes the form of a rotatable arm, for moving the moveable component 226. The actuator 228 is configured to abut the moveable component 226 to move the moveable component 226. There is also a pivot 230 about which the actuator 228 is configured to rotate. The tap assembly 204 also has a channel 232 in which the moveable component 226 slides when moving to alter the proportion of the aperture 224 that is blocked. The tap assembly 204 may further comprise a biasing means (not shown), such as a spring, configured to bias the moveable component 226 towards its first position (i.e. where the aperture 224 is completely blocked). Biasing the moveable component 226 in this way ensures that beverage does not leak accidentally. The moveable component 226 is configured to slide (i.e. translate, or move in a linear direction e.g. within a channel) between its first and second positions. In other words, rotational movement of the actuator 228 is converted into linear movement of the moveable component 226.
The tap assembly further comprises a handle (as described previously but not shown in
The components of the apparatuses and tap assemblies described herein according to the invention are generally made out of plastic, and can therefore be cleaned and sterilised easily. This also means that parts can be machined precisely e.g. by injection moulding. However, the skilled person will appreciate that some or all parts can equally be made from other suitable materials. For example, the handle of the tap assembly is generally constructed from metal and, as described, can be attachable to the tap assembly using magnets. Equally, springs in the apparatus (e.g. the biasing means in the tap assembly or springs in one or more of the valves described herein) may be constructed from metal. Certain decorative elements may also be constructed from metal.
In accordance with another aspect of the invention, there is also provided a package containing ingredients for brewing an alcoholic beverage. Significantly and advantageously, the package is shaped and sized so that it can fit through a standard domestic letterbox.
The package contains ingredients for brewing beer in the apparatus 200 of the invention (including in the alternative arrangement shown in
In this way, the package can fit through a standard letterbox.
The package of the invention is intended to contain refill ingredients for the apparatus of the invention, as well as a steriliser. The package is compact and intended for delivery through a standard domestic letterbox. This means that the consumer does not need to transport the beverage home from a shop and also does not need to be present to accept a home delivery, which would conventionally have been too large to fit through a letterbox. The package of the invention also has additional benefits for the consumer because duty would not need to be paid on the package, reducing cost. The package of the invention also has significant environmental benefits because it reduces the packaging needed for enjoyment of beverages, such as beer, at home. For example, a considerable amount of plastic is conventionally used in packaging for beverages (e.g. plastic holding cans together).
The package and apparatus of the invention can be provided as a kit.
The apparatus 400 comprises a fermentation container 402 (shown in part) for containing and fermenting a beverage (e.g. beer or cider) and a collector 406 (or “yeast dump”) for collecting waste (e.g. yeast) from the fermentation container 402. Of course, the apparatus may also comprise any of the tap assemblies described herein (not shown).
As described previously, before use, the fermentation container 402 is sterilised. During fermentation, the fermentation ingredients (e.g. yeast, a syrup containing pre-hopped malt extract and water) are poured into the fermentation container 402 and the fermentation container 402 is sealed. The mixture is left to ferment in the fermentation container 402 with the fermentation container vertically upright (i.e. in the orientation shown in
In
Once fermentation is complete, the collector 406 is removed from the fermentation container 402. During fermentation, all of the waste yeast has settled in the collector 406 and therefore the beverage in the fermentation container 402 is free of sediment.
As shown in
The collector 406 comprises an inlet 409 that can be moved between a first configuration (
The inlet 409 comprises a stopper 436 that is movable between a first position (
The stopper 436 is biased towards its first position by pressure within the collector 406. The stopper 436 also comprises a float 438 that is configured to float on waste collected within the chamber 434. This is advantageous because it allows the stopper 436 to float on the waste (e.g. waste liquid and/or sediment) that has gathered in the collector 406 during the fermentation process and rise to seal the inlet 409 automatically. The float 438 may be hollow or substantially hollow or at least as hollow as necessary to allow the stopper 436 to float. In the embodiment shown in
The stopper may be configured to gradually release pressure from the collector when the inlet is in its first position to prevent the collector from becoming overpressurised if carbonated beverage remains in the collector. This can be achieved by shaping the stopper to gradually release pressure or by using the surface properties (e.g. materials) of the stopper, for example.
The stopper 436 further comprises a stem 440 extending from the float 438 at least partially through the inlet 409. The stem 440 is shaped to permit fluid flow therethrough. In the figures, the stem 440 has a cross-shaped cross-sectional shape. The skilled person will understand that other shapes (e.g. Y-shaped, cylindrical) could equally be used. These shapes mean that the stopper 436 can permit fluid flow through the inlet 409 when the float 438 is not sealing the inlet 409 (i.e. when the stopper 436 is not in its first (sealed) position.
As shown in
This provides an advantageous arrangement in which attaching the fermentation container 402 and the collector 406 automatically results in the collector inlet 409 moving from its first configuration to its second configuration to permit waste from the fermentation container 402 to enter the collector chamber 434. Similarly, detaching the fermentation container 402 and the collector 406 automatically results in the collector inlet 409 moving from its second configuration to its first configuration to seal the collector chamber 434 and prevent spillage of waste from the collector 406.
The plug 416 of the fermentation container outlet 408 is configured to abut the stopper 436 of the collector inlet 409 to move the stopper between its first and second positions. This abutment also moves the plug 416 between its first and second positions. In other words, when the fermentation container 402 and the collector 406 are attached, the plug 416 of the fermentation container 402 and the stopper 436 of the collector 406 abut each other meaning that both the plug 416 and the stopper 436 automatically move to their second positions to permit waste from the fermentation container 402 to pass through the fermentation container outlet 408 and the collector inlet 409 to gather in the collector 402. Similarly, when the fermentation container 402 and the collector 406 are not attached (i.e. detached), the plug 416 of the fermentation container 402 and the stopper 436 of the collector 406 no longer abut each other meaning that both the plug 416 and the stopper 436 automatically move to their first positions to seal the fermentation container 402 (to maintain pressure) and seal the collector 406 (to prevent spillage of waste). This automatic movement of the plug 416 and stopper 436 is highly advantageous and reduced the amount of user input required. The plug 416 is biased towards its first position by pressure within the fermentation container 402.
In the embodiment shown in
In particular, as will be described below, the tap assembly 504 comprises a movable component 526 that is the same as or substantially the same as movable component 226 shown in
The tap assembly comprises a first conduit 542 for allowing passage of a fluid therethrough and a second conduit 544 for allowing passage of a fluid therethrough. The second conduit 544 is analogous to the aperture 224 of the tap assembly 204 described previously. The movable component 526 is movable between a first position in which passage of fluid is only permitted through the first conduit 542 and at least one second position in which passage of fluid is permitted through both the first conduit 542 and the second conduit 544.
It can be seen that the first conduit 542 comprises a tube 546 (e.g. a flexible tube) that extends into the fermentation apparatus from an anchor 548 within the tap assembly 504. The tube 546 is long and narrow, meaning that the resistance to fluid flow passing through the tube 546 is relatively large which, in turn, restricts the flow rate through the tube 546.
The tap assembly 504 advantageously allows a fermentation container to be tapped selectively via two conduits (the first 542 and second 544 conduits), for example two conduits that resist fluid flow therethrough of the fluid being tapped (e.g. beer). The different resistances may arise from one conduit being longer and/or narrower than the other, in other words the aspect ratio of one conduit may be greater than the other. In the embodiment shown in
Like tap assembly 204, tap assembly 504 further comprises an actuator (not shown) for moving the movable component 526 and a handle (not shown) coupled to the actuator. The handle is configured to be moved a first distance to, in turn, move the movable component 526 a first distance to permit passage of fluid through the first conduit 542 only and a second distance (i.e. further than the first distance) to allow passage of fluid through the first 542 and second 544 conduits. This arrangement, along with the fact that the first 542 and second conduits 544 resist fluid flow to different degrees, allows for optimal frothing and fluid flow throughout the entire tapping procedure, even as the pressure within the fermentation container decreases. For example, where the first conduit 542 applies a greater resistance than the second conduit 544, the handle can be moved a first distance whilst fluid passes through the first conduit 542 only to ensure that the fluid flow is not too fast at high pressure and that the beverage (e.g. beer) is not too frothy. Once the pressure within the fermentation container has reduced by a certain amount, the handle can be moved a second distance and fluid flows through both the first 542 and second 544 conduits. This ensures sufficient fluid flow even at low pressures within the fermentation container because the second conduit 544 applies a lower resistance to the fluid being tapped than the first conduit 542.
In the first position shown in
Of course, even when the second conduit 544 is open (i.e. the movable component 526 is in a second position), some fluid may flow through the first conduit 542 and this is not problematic. However, since flow through the second conduit 544 is easier than through the first conduit 542, minimal flow will occur through the first conduit 542 when the second conduit 544 is open.
As described previously, the handle may be attachable to the tap assembly magnetically.
The tap assembly 604 comprises a tap holder 650 and a tap 652 that is removably attachable to the tap holder. As will be described herein, the tap 652 is rotatable relative to the tap holder 650 between a locked position in which removal of the tap 652 from the tap holder 650 is prevented and an unlocked position in which removal of the tap 652 from the tap holder 650 is permitted.
The tap assembly 604 of the invention serves two key purposes. Firstly, it ensures that the user properly attaches the tap 652 to the tap holder 650 before tapping takes place. Secondly, it ensures that the tap 652 is not accidentally detached from the tap holder 650 once the tap 652 has been attached. Both of these results are important in ensuring proper tapping and preventing spillage or danger from the tap becoming detached accidentally.
As shown in
Whilst the figures show that the tap 652 comprises the protrusion 654 and the tap holder 650 comprises the channel 656, the skilled person will understand that in an alternative embodiment the tap 652 may comprise a channel and the tap holder 650 may comprise a protrusion.
The valve 770 comprises an aperture (not shown in
The actuator 774 is configured to apply variable force to the stopper 772 to vary the resistance of the valve. The provision of a valve where the resistance of the valve can be varied is highly advantageous as this allows for the pressure within the fermentation container to be controlled and varied. This is important as it means that a wide variety of beverages (e.g. lagers, ciders, bitters, stouts, ales) can be fermented at their optimal pressure, resulting in the optimal carbonation. For example, a lager would be brewed at high pressure for a greater degree of carbonation whereas a stout would be brewed at low pressure for little or no carbonation.
The actuator 774 is configured to apply variable force to the spring 776 to variably compress the spring 776, and the spring 776 in turn is configured to apply variable force to the stopper 772 to vary the resistance of the valve. In other words, the resistance of the valve (and therefore the pressure within the fermentation container) can be controlled and varied by varying the compression of the spring by applying different forces to the spring 776 via the actuator 774. The figures show a helical compression spring, but the skilled person will understand that a leaf spring or any other suitable spring or biasing means or resilient member could equally be used.
The actuator 774 is rotatable vary the force applied to the stopper 772. Rotation of the actuator is a convenient and compact way for a user to vary the pressure within the fermentation container. In particular, the actuator comprises a screw thread 778 extending around its circumference that is configured to engage and translate about a protrusion 780 on the valve body 784. The screw thread 778 is shown extending fully through the wall of the actuator 774 but the skilled person will understand that a partial recess could be used. Additionally, the skilled person will understand that the actuator could comprise a protrusion and the valve body could comprise a screw thread.
When the actuator 774 is rotated, it screws upwards or downwards on the valve 770 which varies the force applied to the spring 776 and consequently the force applied to the stopper, meaning that the resistance of the valve 770 is adjusted. This provides a predictable and reliable movement of the actuator and, consequently, a predictable and reliable variation of the resistance of the valve and therefore the pressure within the fermentation container.
As examples,
The apparatus comprises a fermentation container 802 for containing and fermenting a beverage (e.g. beer or cider) and a cap 882 that is attachable to the fermentation container 802 and is configured to seal the fermentation container 802 when the cap 882 is attached to the fermentation container 802. The cap 882 is attachable to and detachable from the fermentation container 802 via corresponding screw threads (not shown) on the cap 882 and the fermentation container 802.
The cap 882 comprises a handle 884 that is rotatable about pivots 886 (e.g. screws or nuts)) between a first position in which the handle 884 is graspable by a user (i.e. where the handle 884 extends perpendicularly to the surface of the cap 882, as shown in
The attachment of the cap 882 to the fermentation container 802 will now be described. To aid this discussion,
The present invention advantageously provides a convenient and elegant way of preventing the cap from being detached from the fermentation container accidentally during fermentation by using the handle as a part of the locking mechanism. This removes the need for additional locking features which simplifies the design.
Once the cap 882 has been screwed onto the fermentation container 802, the handle 884 can be rotated to the position shown in
As shown in
The present invention therefore provides a neat and effective way of preventing accidental removal of the cap using the existing handle of the cap.
As in other embodiment, the fermentation apparatus 800 may further comprise a collector 806 (i.e. a yeast dump as described previously) that is attachable to the fermentation container 802 to collect waste from the fermentation container 802. The collector 806 may have any or all of the features of other collectors (e.g. collectors 202, 302, 402).
As shown in
The present invention has been described above in exemplary form with reference to the accompanying drawings which represent a single embodiment of the invention.
