Heated dispensing apparatus

A dispenser for products which are to be dispensed at elevated temperatures and wherein the product is contained in a container having an outlet with a flexible discharge tube extending therefrom, comprising;

• (a) a receptacle having an outlet opening in the lower portion thereof for receiving the container of product with the discharge tube extending through the outlet opening;
• (b) a heating element heating the product in the container when received in the receptacle to a desired temperature range and maintaining the temperature of the product in that temperature range for a desired period of time:
• and
• (c) a peristaltic pump for compressing a portion of the flexible tube and moving the compressed portion and thereby the heated food product along the tube, said pump including
• (i) a housing,
• (ii) a rotor supported in said housing for rotating about a longitudinal axis of said rotor,
• (iii) a stator adjustably supported by said housing adjacent the rotor,
• (iv) an adjustment mechanism operatively connected to and moving said stator relative to said rotor between a pumping position wherein the stator holds a portion of the discharge tube in fixed pumping position adjacent to the rotor and a loading position wherein the discharge tube can be placed between the stator and rotor;
• (v) rotatable pinch rollers carried by said rotor and arranged to pinch the discharge tube when the discharge tube is held in the pumping position, said pinch rollers moving along the portion of the discharge tube adjacent the rotor to thereby pump product through the discharge tube, and
• (vi) a control mechanism for controllably rotating the rotor and thereby delivering a predetermined amount of heated product;
• and
• (d) means for maintaining the product in the discharge tube in the desired temperature range.

An apparatus for the delivery of viscous food material held at elevated temperatures comprising;

• (a) a frame shrouded with insulating material;
• (b) a receptacle positioned within said frame for holding a container for holding the food material, said receptacle having an opening for receiving said food material and an outlet for dispensing said food material, a portion of said receptacle being made of a heat conductive material;
• (c) a peristaltic pump juxtaposed next to a portion of said receptacle, said pump including
• (i) a flexible tube member communicating with said outlet,
• (ii) a first member secured and stationary with respect to said frame,
• (iii) a second member spaced from said first member and movable with respect to said frame between a closed position and an open position said second member made from a heat conducting material and positioned in a heat conducting relationship with said receptacle portion,
• (iv) a rotating member positioned within a cavity defined by said first and second members, said rotating member together with said second member defining a passage in which a portion of said flexible tube is positioned, said rotating member having a plurality of spaced tube-contacting members for compressing said hose at a point and moving said point of compression along said hose when said second member is in the closed position and abutting said tube member thereby urging said viscous material from said receptacle through said flexible hose and discharging a predetermined amount of said viscous food material;
• (d) a heating element positioned within said frame for heating said portion of said receptacle and thereby said viscous food material within the container within said receptacle, said second member when in said closed position being heated by said portion of said receptacle thereby transferring heat to said flexible hose material within said passage;
• and
• (e) a cam mechanism operatively connected to said second member for moving said second member between said closed and open positions.
