Abstract
An eccentrically positioned rotary piston (11) in an almost round casing (10) is driven by a pressure controlled hydraulic motor (27) with radial slots (12), guided rams (13). The radial position of the rams (13) is set with a control valve (15). A removable insert (16) in the housing (10) serves to alter the pre-compression of the material. This ensures that gas escapes from ground meat intended for molding patties and that the material is pressed at an even pressure into the mold plate opening (23). No changes are necessary when altering the mold plate size because the driving pressure is limited and this determines the filling amount.
Claims16
Portioning machine to fill mold with plastic food material such as ground meat and the like with a hopper (17) to hold a material supply, a feeding channel (19,20) to feed the material to a mold filling place (23) and with a compression system (1) between the hopper and the feeding channel the characteristic of which is that the compression system is equipped with an almost circular cylindrical housing (10) having an inner wall, eccentrically arranged rotary piston (11) with several radially adjustable flat rams (13) and a fixed control disc to set the radial position of the rams (13) depending on the angle of the rotary piston (11) and that the feeding channel (19,20) is also a compression chamber (20) and also has a control system (27) to drive the rotary piston (11) which either starts or stops the piston (11) from rotating depending on the pressure of the material in the compression chamber so that the material being filled into a mold is at a substantially constant pressure during the filling of the mold;
- the portioning machine including at least one insert (29) to adjust the distance between the ram (13) and the inner wall of the housing (10) for the gradual adjustment of pressure on the material.
A portioning machine to fill a mold with a plastic food material comprising:
- (a) a hopper to hold a material supply;
- (b) a material compression system to feed material to and fill a mold, the compression system being fed material by the hopper, the compression system including an almost circular cylindrical housing having an inner wall, an eccentrically arranged rotary piston with several radially adjustable flat rams, a fixed control disc to set the radial position of the rams depending on the angle of the rotary piston and a feeding channel through which material is fed to a mold, the feeding channel including a compression chamber for feeding material to a mold;
- and
- (c) a control system including means for driving the piston, and means for controlling the piston driving means to maintain material in the compression chamber at a substantially constant pressure so that material being filled into a mold from the compression chamber is at a substantially constant pressure during the filling of the mold;
- the portioning machine including at least one insert (29) to adjust the distance between the ram (13) and the inner wall of the housing (10) for the gradual adjustment of pressure on the material.
