LINE PASTEURIZER Russian patent published in 1998 - IPC

FIELD: food-processing industry. SUBSTANCE: pasteurizer has pasteurizing, recuperation and conditioning sections, temperature-control device with control valve mounted at heat-carrier line and product flow change-over device positioned at conditioner outlet end. Temperature control device has temperature conditioner, hydraulic cylinder with weight and two guiding poles. Conditioner has hermetically sealed cavity positioned adjacent to product containing cavity and connected with hydraulic cylinder cavity. Interconnected cavities are filled with thermosensitive liquid. Hydraulic cylinder is mounted in vertical position. Weight is fixed on upper end of hydraulic cylinder stem for movement in vertical plane in guiding poles and is provided with two cam planks. Control valve and temperature scale are disposed on one pole and flow change-over device is mounted on other pole. Control valve and flow change-over device are mounted in position suitable for their actuation before their stems and levers come into contact with cam planks of weight during movement of the latter in guiding poles. Temperature control device is formed as monoblock direct-action mechanical regulator and combines thermosensitive and actuating functions. EFFECT: simplified construction, reduced capital and operating costs and enhanced reliability in operation. 2 dwg
