The present invention relates to an apparatus for roasting coffee beans and associated processing of these beans, either grinding and/or extraction of a final coffee beverage. The invention further relates to an associated method for roasting and grinding.
In all domains of food and beverage preparation, the quality of the prepared food or beverage requires, at least: adequate quality of the raw product; right tools (machines, devices, etc.) and knowledge and skills to ensure the right preparation processes.
Hot beverage preparation, more particularly coffee preparation and its derivates, also obey the same rules.
Since the very first invention of a coffee extraction machine, the associated techniques have heavily evolved during the last decades. It is known in the state of the art that the first machine for making espresso was built and patented in 1884 by Angelo Moriondo of Turin, Italy. An improved design was later patented on April 28, 1903, by Luigi Bezzera. The founder of the La Pavoni company bought the patent and from 1905 produced espresso machines commercially on a small scale in Milan. Multiple machine designs have been created to produce espresso. Several machines share some common elements, such as a group head and a portafilter. An espresso machine may also have a steam wand which is used to steam and froth liquids (such as milk) for coffee drinks such as cappuccino and caffe latte.
Present techniques for preparing a coffee beverage involve a skilled person (called a Barista) and dedicated machines/devices to prepare the said coffee beverage. Typically in roast and ground (R&G) coffee, Baristas have the knowledge and the science of coffee to ensure the quality of the prepared cup depending on type of beverage to the prepared, the type of coffee used and the material/means used in the mentioned preparation.
Typically, depending on the type of coffee beverage to prepare (espresso, drip coffee type, cold brew, etc.), as well as on the method of extraction used (drip, Chemex, espresso machine, etc.), the Barista chooses the type of coffee (origin, roasting level, etc.), as well as the setting of each machine in the preparation method (the grinder parameters, the extraction method, the water temperature, etc.). In other words, all relies on the knowledge of the Barista, so these types of preparations need a skilled or trained person to ensure that all parameters are correctly set and that the right procedure is followed during the preparation.
Single serve based systems for preparing food or beverages, typically from the starting product comprised in a container, preferably a capsule, are well known in the state of the art. Capsule-based systems have put beverage and food extraction and/or reconstitution on a higher level in terms of:
The fact that the product used is controlled in factories until the last step (roasting, dosing, grinding) and that is tailored to the dedicated extraction system, positions the single serve system potentially higher in terms of end cup quality. Additionally, certain systems in the market use also a coding system to adapt the machine extraction parameters to the right capsule (product) used to get the best out of it.
However, the ecological impact of such systems, as well as the cost per serve, are high, especially when ending with complex technical packaging, as the capsule is used as an extraction cell, including complex functions such as water diffuser or jet, opening membrane, air suction system, filter, pyramid plate... etc.
Fully Automatic machines using roasted beans to prepare a coffee beverage are widely known in the state of the art. In the 80’s fully automated machines of diverse brands (Jura, Saeco, etc.) have followed the trend of automation. Consequently, they have grouped all the functions done by a Barista (skilled person preparing coffee beverages) in a single machine, including grinding of coffee beans, dosing, tamping, as well as extraction of the coffee beverage. As a consequence, in these machines, the operator only needs to fill the bean hopper and, if the machine is not connected to a water line, add water to a reservoir. The rest is automatically done by the machine itself.
Fully Automatic machines are growing in the market as they simplify the extraction steps and can be used by a non-skilled person. However, they are bulky and complex, and more importantly, they are considered to be a compromise between preparation quality and convenience.
Fully automatic machines take away the ability to manually tamping and grinding the coffee, which may affect the quality of the espresso, as this setting cannot be changed from a beverage to another.
Typically, the grinder can be adjustable to get the right grind size for the desired beverage: however once adjusted, the same grind size is used for all the beverages. And most importantly, the machine is never adjusted by the user according to the different coffee beans used. This results in a compromise of quality and convenience of the final beverage delivered.
The main goal of the present invention is to achieve similar end results of those achieved with capsule systems without using single serve packaging, and/or obtaining similar results as Baristi obtain without Barista specific skills needed. The goal is to use a communication between the beans preparation device (roasting device) and the coffee processing device (coffee preparation machine and/or grinder and/or fully-automatic or semi-fully automatic machine).
By means of a wireless connection and/or an application that transfers/communicates parameters of the roasted beans (output form the roasting device) to the processing device (coffee preparation machine), the system of the invention is able to adapt the processing parameters used in order to replace the Barista (skilled person) know-how by an AI (Artificial Intelligence) system.
The system of the present invention allows the coffee machine to adjust its processing parameters according to the targeted output needed (beverage type) and as a function of the used beans (info from the roasting device). The goal is to ensure the integrity of the procedure and the information by communicating the right parameters to be used.
In difference to standalone fully automated machines, the system according to the present invention brings the right process to the right needed beverage type in function of the product.
In difference to single-serve systems (typically using capsules containing the coffee or the product to be processed), the system of the present invention does not use a single packaging for each beverage preparation, but a multipack, and uses accessory-devices for extraction/processing.
