ANORDNUNG ZUM PUMPEN UND DISPENSIEREN VON HOCHVISKOSEN FLUESSIGKEITEN ODER DERGLEICHEN

摘要

The invention concerns an arrangement of pumps and dispensers for highly viscous liquids with a high solids contents or a content of solids in larger segments, in particular for use with viscous foodstuffs. The substance to be delivered is supplied in a flexible, collapsible plastics container (1). The plastics container is inserted in a pressure vessel (3) connected to a pressure generator (4) which introduces a pressurized medium, in particular air or water, into the space between the plastics container and the pressure vessel. The substance to be delivered is discharged at the end of a delivery tube (7) connected in a pressure-tight manner to the plastics container. The delivery tube is associated with a squeezing device (10-13) comprising a plurality of functionally harmonized squeezing elements which force the substance to be delivered through the delivery tube. The resultant arrangement for discharging viscous liquids is structurally simple and ecological and has optimal microbiological properties.
