ABSTRACT:
Methods and apparatus for dispensing controlled portions of food products having high levels of tack. An apparatus for dispensing portions of food has a portioning chamber including a first end defining a ram mating orifice, a second end defining an expulsion orifice, and a body portion defining an inlet orifice intermediate the two ends for introducing bulk food product into the chamber. Disposed in the chamber is a piston having a face sized to substantially slidingly fit therein. An actuatable ram is located at the first end and coupled to the piston for causing controlled movement of the piston. The actuator is operated by a controller wherein the controller first causes the ram, by way of the actuator, to fully extend, then causes the ram to partially retract so that the face of the piston retracts no further than the inlet orifice, and then causes the ram to again fully extend. A method utilizes a portioning chamber that includes a first end defining a ram mating orifice, a second end defining an expulsion orifice, and a body portion defining an inlet orifice intermediate the two ends for introducing bulk food product into the chamber, as well as a piston having a face.-disposed in the chamber. The method comprises the steps of a) introducing a predetermined amount of food product into the chamber via the inlet orifice when the apparatus is in the nominal state; b) extending the piston face beyond the expulsion orifice; c) partially retracting the piston face so that it is within the chamber; d) extending the piston substantially as far as in step b); e) and returning the piston to its position in step a). In both the apparatus and method, compressed air can be presented to a foramenous piston face to facilitate dislodgment of food product.
