Abstract
The invention relates to a method and a dispensing device for rapidly and efficiently heating/cooling a flowable food product whereby removable cassettes are provided for receiving a pouch containing food; the cassettes comprising pairs of opposed thermal conductive surfaces wherein the surfaces delimit together a limited spacing adapted to contact a pouch and means for applying heat to said at least pair of cassettes.
Claims26
A food dispensing device having an enhanced capacity for controlling temperature of a flowable food product comprising:
- a housing defining an interior cavity;
- at least a first pair of opposed thermal conductive surfaces delimiting a spacing therebetween adapted for receiving a first pouch having two extensive walls, said thermal conductive surfaces being substantially oriented within the housing and spaced sufficiently closely to each other for maintaining the pouch substantially in a standing position, with the thermal conductive surfaces being arranged to intimately contact said extensive walls of the pouch;
- means for directly heating or cooling said first pair of opposed thermal conductive surfaces for transferring heat with the extensive walls of the pouch by contact therewith;
- and
- means for connecting the first pouch for selectively delivering portions of food from the first pouch.
A food dispensing device having an enhanced capacity for controlling temperature of a flowable food product, comprising:
- a housing defining an interior cavity;
- at least first and second pairs of opposed thermal conductive surfaces, each pair of thermal conductive surfaces delimiting a spacing therebetween dimensioned for receiving first and second pouches, respectively, each pair having two extensive walls, said thermal conductive surfaces being substantially oriented within the housing so that the respective pouch substantially remains in a standing position, with the thermal conductive surfaces being arranged to intimately contact said extensive walls of the respective pouch;
- means for controlling the temperature of said first pair of opposed thermal conductive surfaces;
- and
- means for connecting to the first pouch for selectively delivering portions of food from the first pouch;
- wherein said second pair of thermal conductive surfaces is maintained in a non-dispensing mode.

A dispensing device for rapidly and efficiently controlling a flowable food product, comprising at least a pair of removable cassettes configured for receiving a pouch that comprises two opposed sidewalls containing at least about 2 Kg of food;
- the cassettes comprising pairs of opposed thermal conductive surfaces wherein the surfaces delimit together a spacing adapted to contact a pouch and means for controlling temperature of said pair of cassettes, wherein the spacing between the two opposed thermal conductive surfaces of the first and second pairs is at most about 40 mm such that the opposed surfaces retain the pouch in a standing position for directly transferring heat between the opposed surfaces and the sidewalls of the pouch.
A dispensing device for dispensing flowable food product comprising:
- a housing defining an interior cavity;
- at least one pair of removable identical cassettes within the housing;
- each being adapted for receiving a pouch containing food;
- said cassettes comprising pairs of opposed thermal conductive surfaces wherein the surfaces delimit together a spacing adapted to receive a pouch;
- means for controlling temperature of said at least pair of cassettes;
- wherein the cassettes are interchangeable.
A method for rapidly and uniformly controlling temperature and delivering a flowable food comprising:
- providing a narrow profiled pouch comprising two extensive walls connected together by a plurality of peripheral edge portions to form a closed interior for the food of relatively low width;
- and a fitment to deliver the flow of food through an outlet;
- said fitment being sealed across one edge portion of the pouch;
- positioning said narrow profiled pouch between two opposed vertically oriented thermal conductive surfaces delimiting a spacing therebetween adapted for receiving the pouch with the extensive walls intimately contacting the thermal conductive surfaces;
- directly heating or cooling the thermal conductive surfaces for heating or cooling the extensive walls of the pouch by conduction transfer;
- providing valve means to selectively control the flow of food from the pouch.
A method for ensuring a steady supplying in warm food product within a dispensing device comprising:
- providing a pair of cassettes containing food within a container;
- said cassettes being interchangeable within the dispensing device;
- providing heat to each of said cassettes to warm the food product;
- and
- dispensing food from one of said heated cassette while holding the other cassette warm.
A dispensing device having an enhanced capacity for controlling the temperature of a flowable food product, comprising:
- a housing defining an interior cavity;
- a bottom support surface within the housing;
- and
- a first pair of directly heated contact surfaces spaced from each other sufficiently closely for maintaining the pouch substantially in a standing position on the bottom support surface, with the contact surfaces being arranged to intimately contact said extensive walls of the pouch;
- a heater associated with the first pair of opposed contact surfaces for directly heating the contact surfaces such that the heat is transferred to the pouch through the contact surfaces by the intimate contact of the contact surfaces with the extensive walls of the pouch;
- and
- a pump associable with the first pouch for selectively delivering portions of food from the pouch.
