Abstract

An apparatus and method are disclosed to force a frozen food product out of a receptacle by moving a piston back and forth within the receptacle. Pressurized air is used to move the piston toward the frozen product, thereby forcing the frozen product out of the receptacle. To move the piston away from the frozen product, the pressurized air is sent through a venturi that also connects to the receptacle. The flow of pressurized air through the venturi creates a vacuum in the receptacle. The vacuum pulls the piston away from the frozen product.
