ELASTIC PUMP FOR A PERISTALTIC PUMP, PERISTALTIC PUMP FOR GUIDING FLOWABLE MASSES OR POWDER, PORTIONING UNIT FOR PORTIONING FLOWABLE MASSES OR POWDER, ARRANGEMENT COMPRISING SEVERAL PORTIONING UNITS OF SAID TYPE, METHOD FOR PORTIONING FLOWABLE MASSES OR POWDER

摘要

The invention relates to a portioning unit (21) comprising an elastic pump for a peristaltic pump (31), a peristaltic pump (61) acting upon the elastic pump for a peristaltic pump (31) and a portioning unit (41) for portioning flowable masses and powder. Said portioning unit (41) comprises a first pinch valve (42) which is arranged downstream of the peristaltic pump (61), and a second pinch valve (47) which is arranged downstream of the first pinch valve (42). Said pinch valves (42, 47) are mechanically controlled. The invention relates to an arrangement with several adjacently arranged portioning units (21), a pump for a peristaltic pump, a peristaltic pump and to a method for portioning liquid masses and powder by means of said type of portioning unit (21).
