A peristaltic batcher comprises an elastic hose with a movable portion and immovable portions, passed between a roller and the shaft of an electric drive motor and carrying a squeezing means on one of its immovable portions. The roller and the shaft are connected by a means for transmitting counter-rotation from the shaft to the roller and permitting the distance between them to be changed. Connected to the drive for moving the roller and the squeezing means by a batching direction reversing switch, to the electric drive motor and to two transmitters indicating the terminal positions of the movable portion of the elastic hose is a reversing device of the control unit which also comprises a pulse-controlled cut-in switch connected with the reversing device, and a pulse-controlled cut-out switch. The peristaltic batching system is comprised of at least two tandem-connected peristaltic batchers. |
