Abstract
An extruding apparatus for intermittently supplying a predetermined quantity of highly viscoelastic material, e.g. food material. The apparatus has a hopper having a supply pump, a supply pipe having one end connected to the pump and the other end to an extrusion valve, and an accumulator (constant pressure device) mounted to the extrusion valve for maintaining the pressure of the food material in the extrusion valve at a predetermined constant pressure.
Claims5
An apparatus for intermittently extruding predetermined quantities of food material onto a conveying means, the apparatus comprising:
- a hopper for containing food material, the hopper including an exit port and a supply pump for pumping the food material through the exit port;
- an extrusion valve assembly including a housing connected to receive the food material pumped through the exit port of the hopper;
- and
- an accumulator for maintaining the food material located in the extrusion valve at a predetermined pressure by expanding to receive the food material from the housing when a pressure of the food material in the housing becomes greater than the predetermined pressure, and by contracting to push food material into the housing when a pressure of the food material in the housing becomes less than the predetermined pressure.
An apparatus for intermittently extruding predetermined quantities of food material onto food masses conveyed on a conveying means such that one of the predetermined quantities is deposited on each of the conveyed food masses, the apparatus comprising:
- a position sensing means located above the conveying means for generating detection signals indicating the presence of one of the food masses;
- a hopper for containing food material located above the conveying means and downstream of the position sensing means, the hopper including an exit port and a supply pump for pumping the food material through the exit port;
- an extrusion valve assembly including a housing connected to receive the food material pumped through the exit port of the hopper;
- an accumulator for maintaining the food material located in the supply pipe and the extrusion valve at a predetermined pressure by expanding to receive food material from the housing when a pressure of the food material in the housing becomes greater than the predetermined pressure, and by contracting to push food material into the housing when a pressure of the food material in the housing becomes less than the predetermined pressure;
- and
- means for controlling the extrusion valve and supply pump in response to the detection signals such that the extrusion valve deposits one of the predetermined quantities of food material onto each detected food mass.
