The present invention relates to cheese making, and more specifically to a self-contained, mobile dairy plant for making cheese.
In order to manufacture cheese from milk, a cheese processing plant is normally utilized to convert the milk through various steps into cheese. The processing plant includes a number of different types of machinery that are utilized within the plant to process the milk and other necessary components for making cheese through the various steps in order to manufacture the cheese. This machinery normally includes milk pasteurization equipment, cheese make vats used for the formation of curds and whey from the pasteurized milk and other added ingredients, such as bacteria cultures, which are subsequently separated to remove the curds from the whey, and then pressed on a suitable finishing table in order to form the cheese.
However, previously, in order to manufacture cheese on a commercial scale, the size of the components utilized required a large, fixed-site processing plant to be constructed, requiring great expense and time. Also, as different types of cheese require different types or variations of the cheese making machinery, in order to be able to make these different types of cheese in a single plant, even more equipment is required, with an associated greater expense. As a result, the ability to commercially make and sell cheese is beyond the means of many individuals that produce the raw materials for making cheese, such as dairy farmers. Therefore, it is desirable to develop an apparatus and method for use in making cheese products that is extremely compact with regard to the prior art cheese-making plants that are known and that also can be utilized by a number of different individuals for making cheese, such as by making the apparatus mobile.
According to a primary aspect of the present invention, a modular dairy processing, and preferably a cheese-making apparatus is provided in which the apparatus is entirely enclosed within a mobile trailer capable of being attached to a vehicle for movement of the trailer between locations. The trailer includes a cheese making area in which all of the required cheese-making or other dairy processing machinery, namely, a milk pasteurizer, a cheese-make vat, and a cheese finishing apparatus, is contained such that the entire cheese-making process can be carried out in the cheese-making area. The trailer also includes a number of storage containers attached to the trailer and connected to the machinery in the cheese-making area. These containers are capable of holding milk and potable water to be used in the cheese-making process, such that all of the materials required for the entire cheese-making process are contained within the trailer. Further, the trailer also includes a chilled storage area for the cheese made within the cheese-making are of trailer, such that the cheese can be stored within the trailer for further conditioning and/or preservation of the cheese. Also, the trailer can optionally include a retail area from which the cheese made in the cheese-making area and/or stored in the storage area can be sold directly from the trailer.
According to another aspect of the present invention, all of the electrical and mechanical system connections between the various dairy processing machinery disposed within the cheese-making area of the trailer are not connected to any source outside of the trailer, such that all of the raw materials used and waste created by the apparatus is contained exclusively within the trailer during all phases of the dairy processing occurring within the trailer. Additionally, many of the systems utilized in the cheese-making and storage areas of the trailer are closed loop systems, such that the cheese-making and storage areas within the trailer generate much less waste than a conventional dairy processing plant.
According to still another aspect of the invention, the apparatus includes an observation deck disposed on the exterior of the trailer to enable individuals on the exterior of the trailer to view the various stages of the cheese-making process or other diary processing occurring within the trailer for educational or various other purposes. The observation deck can also be utilized as a sales area in addition to observing the process of cheese-making within the trailer by providing an additional location adjacent the observation deck through which cheese made within the trailer can be purchased from the retail are in the trailer by individuals on the deck.
Numerous other aspects, features, advantages and objects of the present invention will be made apparent from the following detailed description taken together with the drawing figures.
The drawings illustrate the best mode currently contemplated as practicing the present invention.

The cooler area 52 is a refrigerated storage area in which cheese formed in area 50 can be placed for curing and/or storage until sale and enables the cheese made within the apparatus 10 to be stored within the trailer 12 once it is made. As stated previously, the storage area 52 is accessible through the door 80 connecting the dairy processing area 50 and the storage area 52, or through a separate door 84 extending through side wall 18 of the trailer 12 that provides access from the storage area 52 to the exterior of the trailer 12. A number of additional support surfaces or shelves (not shown) can also be positioned on the respective walls of the storage area 52 to hold various items and finished cheeses in the area 52. The storage area 52 also has a partition 88disposed opposite partition 82 in which is located a door 86 that extends through the partition 88 to allow access between the cooler 52 and the utility area 54. The partition 88 separates the storage area 52 from the utility area 54, and preferably is formed similarly to the partition 82 to function as an insulating wall.
A number of chillers 90 capable of cooling the storage area 52 to the desired temperature are positioned within the utility area 54 and are operably connected to a ventilation unit 89 disposed within the storage area 52 to distribute the cooled air from the chillers 90 throughout the storage area 52. The storage area 52 is also formed similarly to the dairy processing area 50, with a floor, side walls and ceiling formed of a waterproof and washable material, such as stainless steel, plastic or a combination thereof to enable the storage area 52 to be cleaned by spraying the area 52 with wash water. The storage area 52 also includes a drain (not shown) that directs the wash water out used to clean the cooler 52 of the storage area 52, such as to one of the storage tanks 48 for collection and later disposal.
The utility area 54 is formed as necessary in order to enclose various operating mechanisms for the apparatus 10, such as the chillers 90 mentioned previously. The utility area 94 also includes a hot water heater 91 and a boiler 92 preferably operably connected to a water storage tank 48 and used to provide a supply of hot water to the various components of the apparatus 10. Further, other mechanisms, such as circuit breakers (not shown), pumps (not shown) and generators (not shown), as well as the associated piping, valves, conduits and switches (not shown) are disposed in the utility area 54 to enable the apparatus 10 to function in a completely self-sufficient manner. However, in a preferred embodiment, the utility area 54 does include a power connection (not shown) for engagement with an exterior power source to supply the necessary electrical power to the apparatus.
A partition 94 separates the utility area 54 from the mechanical area 56 and, in a preferred embodiment, does not include a door, such that the mechanical area 56 is accessible only from an access panel (not shown) disposed on one or more of the side walls 18 or 20, or the front wall 22 of the trailer 12. The mechanical area 56 includes a number of mechanical components, such as a water storage tank 96 which can be operably connected to the hot water heater 91 or boiler 92, or to one of the chillers 90, and a number of compressors 100. The compressors 100 are operably connected to chillers 90 and the ventilation unit 89. The pasteurizer 60 and make vat 62 are connected to the boiler 92 which provides the supply of hot water in a closed loop system via piping system 101a to avoid the contamination of the contents of the pasteurizer 60 and vat 62 and/or waste of the heated water. Additionally, water cooled by the chiller 90 is circulated to the pasteurizer 60 and optionally to the brine tank 74 via piping 101b in order to cool these elements as desired. Circulation of the cooled water is also done in a closed loop manner, such that the cooled water circulated between the pasteurizer 60 and tank 74 does not contaminate the contents of the pasteurizer 60 or brine tank 74, or generate additional waste water. The piping 101a and 101b is constructed in the trailer 12 in order to allow the piping 101a and 101b to be readily attached to and disconnected from a number of different types of dairy processing equipment, to enable the area 50 to be configured as necessary for the desired dairy processing function. Other mechanical components, such as a generator (not shown) used to operate lights (not shown) and other electrical devices, such as the chart recorder 66 and controls 77, and electrical outlets disposed in the various areas 50-56, and an air compressor (not shown), among others, can be placed within either of the utility area 54 or the mechanical area 56 for operating various components of the apparatus 10 that are positioned within the dairy processing area 50 after construction of the trailer 12.

The tank 102 includes an inner shell 111 spaced from and disposed within an outer shell 112, that are each formed of waterproof materials capable of withstanding the pasteurization temperatures generated within the tank 102, such as stainless steel. The outer shell 112 completely surrounds the inner shell 111 and includes a fluid inlet 113, and a fluid outlet 114 each connected to piping 101a and 101b to receive heated and cooled water from the water boiler 98 and the refrigeration unit 89 to control the operating temperature within the tank 102. The inner shell 111 includes an inlet 115 connected via the pumps 58 to one or more of the storage tanks 48 to enable raw milk from the tank 48 to be pumped into the inner shell 111 for pasteurization. The inner shell 111 also includes a sloped bottom surface 116, best shown in
During the pasteurization of the milk in the tank 102, the milk, and any additives introduced through the opening 106, are agitated to increase the efficiency of the pasteurization by an impeller 118 disposed within the inner shell 111 adjacent the bottom surface 116 that is connected to a shaft 119 extending out of the tank 102 through the top end 105 and operably connected opposite the impeller 118 to a motor 120. The speed of the motor 120 and corresponding speed of the impeller 118 are controlled by the controls 77 that are operably connected to the motor 120, or by any other suitable automatic or manually operated control means. Further, after all of the pasteurized milk has been drained from the tank 102, the tank 102 can be cleaned in a C.I.P. manner by directing wash water via the pump 58 into the inner shell 111 through the inlet 115, and removing the dirty wash water through the outlet 117 for collection in one of the storage tanks 48 for later disposal.

The make vat 62 also can function as a curd holder through the use of a curd mill 132 releasably attached to the container 122 of the vat 62. The curd mill 132 includes a pair of rails 134 and a pair of brackets 136 and 138 extending between adjacent ends of each rail 134 and engageable with opposed portions of the side wall 126. The rails 134 are spaced from one another and support a housing 140 therebetween that includes a number of blades (not shown) disposed adjacent a lower end 141 of the housing 140, near the rails 134. A plunger 142 is positionable within the housing 140 and can be urged through the housing 140 either manually or automatically to force curds positioned within the housing 140 against the blades, thereby cutting the curds into smaller sections defined by the apertures (not shown) defined between the blades within the housing 140. The plunger 142 is pivotally connected to a handle 144 which, in turn, is movably connected to a support 146 fixedly connected to one the rails 134.
The whey generated by the agitation of the pasteurized milk within the make vat 62 and resulting production of the curds can be removed from the vat 62 through a drain 147 disposed in the bottom wall 124 on the container 122. The drain 147 is preferably operably connected to one of the storage tanks 48 by a pipe or other conduit (not shown) extending between the vat 62 and the tank 48 in order to contain the whey within the tank 48 until such time it is desired to discharge the whey from the tank 48 for various purposes, such as to feed livestock or simply for waste disposal purposes.
The curd formed in the make vat 62 can then be transferred to the multifunction finishing apparatus or table 64, best shown in

Other configurations for the apparatus 10 are also possible. For example, instead of being configured for use as a cheese-making plant, the trailer 12 can be formed to include equipment (not shown) in the dairy processing area 50 that is utilized to perform other dairy processing functions, such as yogurt making or ice cream making functions, among others. For these purposes, the dairy processing area 50 is either initially configured with the required dairy processing equipment for these alternative functions, or the cheese-making equipment described previously can be removed and replaced by the equipment required for the different dairy processing function to be performed in the trailer 12. This is possible due to the initial configuration or construction of the trailer 12 to include the various electrical and mechanical systems, described previously, which can readily be connected to various types of dairy processing equipment. Thus, the apparatus 10 formed using the trailer 12 can be configured as desired at any point during of after the initial construction of the apparatus 10, making the apparatus 10 truly modular in construction.
