Abstract
The present invention provides a food packing machine which includes the following components: a piston mounted for reciprocation during an operating cycle between a pair of limit positions toward and away from a cake forming cavity, for compressing food material in the cavity; bias apparatus for exerting pressure on the piston to provide compression pressure on the material, the bias apparatus including a resilient material mounted to the piston, and a seat to which the resilient material is also mounted to effect a resilient mounting between the piston and the seat; and pressure relief apparatus for selectively urging the set away from the piston to reduce the bias thereon upon reception of a predetermined signal. The machine normally also includes a sensor for sensing when the machine is deactivated, and a signal device for providing the signal to the pressure relief apparatus when the sensor determines that the machine is deactivated. This prevents over-compaction or over-drainage of the food product being packed when the machine must be stopped during an operating cycle.
