Abstract
A method and apparatus is disclosed for automatically controlling operation of a juice finishing machine of a type having a cylindrical perforated screen in a housing forming an inlet for introducing initial juice or the like into an interior portion of the screen, temperature of juice solids in the pad area and temperature of the initial juice entering the machine being separately monitored and converted to proportional electrical signals, a differential controller establishing a differential output signal proportional to the differential between the sensed temperatures, the differential electrical signal being converted to a pneumatic signal suitable for regulating operation of the actuator means in order to automatically control finished quality of juice product from the machine. A fail-safe control is also provided for establishing a predetermined setting for the actuator means if the differential electrical signal exceeds predetermined limits.
