Abstract: The present invention is a modular, self-contained, mobile dairy-processing plant capable of producing cheese and other dairy products from raw milk stored within the device and able to be moved to various locations in a simple and easy manner using various systems constructed in the mobile plant. The plant takes the form of a trailer connectable to a semi-tractor for transportation of the trailer to any number of locations. The trailer includes storage tanks for holding raw milk, potable water for use in the dairy processing, and for containing gray water and other waste products generated by the plant for later disposal. For a cheese-making plant configuration, the trailer includes a C.I.P. batch pasteurization unit, a multipurpose make vat, a multipurpose finishing table and a brine tank that are used to form various cheeses from the milk held within the storage container on the device.
