Abstract: The invention relates to an automatically-limiting electric sausage filler and control methods thereof.

Abstract: In a device for pumping meat-containing products, such as pieces of meat, meat paste and meat pulp (dough), it is aimed at avoiding problems of the meat forming bridges in a feed space, of meat remaining in the device during a too long time, of too much churning up of the meat and to provide a simple device adapted to discharge at will a continuous meat discharge flow under constant pressure or at a constant flow rate. Thereto, there is a feed space with means for feeding the meat under pressure to one of a number of cylinders with reciprocating pistons or the like, acting in parallel, with a controlled valve in the delivery line between each piston and a common discharge duct. Several feed means are proposed, depending on the application of the devices for pieces of meat on the one hand or for paste or pulp.

Abstract: A volumetric apparatus for portioning fluidic material into fractions of predetermined size includes a housing having an inlet and an outlet, and a piston movable in the housing and defining a product portioning chamber and a compression chamber. Fluidic material is fed into the product portioning chamber through the inlet under pressure when the inlet is open and the outlet is closed, the pressurized fluidic material forcing the piston from a first position by a preset distance such that a predetermined volume of the fluidic material is fed into the product portioning chamber. Thereafter, the piston is driven from the second position to the first position when the inlet is closed and the outlet is open so as to deliver the portioned fluidic material from the product portioning chamber through the outlet.
