FIELD: food-processing industry, in particular, processing of tea mass by pressure. ^ SUBSTANCE: apparatus for controlling pressure under roller press piston has pressure sensor with electric output signal. Said sensor is connected with flexible pipeline disposed along perimeter between wooden pad and metal base of roller press and filled with liquid. Roller press is characterized in that pressure sensor is built into press, said sensor having hollow pipeline filled with liquid, hydraulic pressure sensor, stable voltage source, amplifier, standardizing converter and registering instrument. ^ EFFECT: improved quality of tea owing to controlling of pressure under piston of roller press. ^ 2 dwg |
