Chilled product dispensing system

Claim 1

An apparatus for cooling and dispensing uniformly chilled flowable food product through a dispensing tube extrusion head past a thermal conductive extrusion head projection for release of the uniformly chilled flowable food product, comprising: a cold barrel encased elongated tubular product container tube container, flexible product bag inside the tube, a dispensing tube, extrusion head and projection and dispensing head port; the barrel and elongated tubular product container having a pressurized gas source valve means at a first end and a dispensing tube extrusion head and product release head assembly at a second end; the dispensing tube, extrusion head and projection constructed of thermal conductive materials; the dispensing tube being inserted into an open end of the bag contained in the elongated tubular container, the dispensing tube and the tubular container sharing a common axis and the dispensing tube substantially filling the inside diameter of the tubular container and extending into the open end of the flexible bag and the contained product up to 40 to 60% of the length of the tubular container with both the tubular container and the dispensing tube defining a cylindrical container for chilled food product contained in the flexible bag, the flexible bag being opened at a second end of the tubular container enclosed at a first end: the dispensing tube and tubular container being pressure sealed against a dispensing head by O-ring means; said head defining a dispensing passage past the projection and open for release of said product upon opening of valve means; and valve means for selectively providing pressurizing gas to the barrel and tubular container chamber through activation of valving means which open the dispensing passage for release of uniformly chilled flowable food product.

Claim 2

An apparatus for cooling and dispensing uniformly chilled flowable food product through a dispensing tube extrusion head past a thermal conductive extrusion head projection for release of the uniformly chilled flowable food product, comprising: a cold barrel encased elongated tubular product container tube container, flexible product bag inside the tube, a dispensing tube, extrusion head and projection and dispensing head port; the barrel and elongated tubular product container having a pressurized gas source valve means at a first end and a dispensing tube extrusion head and product release head assembly at a second end; the dispensing tube, extrusion head and projection constructed of thermal conductive materials; the dispensing tube being inserted into an open end of the bag contained in the elongated tubular container, the dispensing tube and the tubular container sharing a common axis and the dispensing tube substantially filling the inside diameter of the tubular container and extending into the open end of the flexible bag and the contained product up to 40 to 60% of the length of the tubular container with both the tubular container and the dispensing tube defining a cylindrical container for chilled food product contained in the flexible bag, the flexible bag being opened at a second end of the tubular container enclosed at a first end: the dispensing tube and tubular container being pressure sealed against a dispensing head by O-ring means; said head defining a dispensing passage past the projection and open for release of said product upon opening of valve means; and valve means for selectively providing pressurizing gas to the barrel and tubular container chamber through activation of valving means which open the dispensing passage for release of uniformly chilled flowable food product.

Claim 11

A method for cooling and dispensing uniformly chilled flowable food product comprising: storing the chilled food product within a food dispenser housing enclosed in a cold product barrel; pressurizing a first closed end of a flexible bag containing the food product, said bag contained in a cylindrical and elongated tubular product container and having a second open end; extruding the chilled food product through an extrusion head mounted on a dispensing tube inserted into the food product through the open end of the bag said extrusion head having an extrusion head projection; avoiding softening of the chilled flowable food product after extrusion into a dispensing port by means of a heat sink created by the dispensing tube, connected extrusion head and extrusion head projection; and dispensing a uniformly chilled flowable food product.

Claim 12

A method for cooling and dispensing uniformly chilled flowable food product comprising: storing the chilled food product within a food dispenser housing enclosed in a cold product barrel; pressurizing a first closed end of a flexible bag containing the food product, said bag contained in a cylindrical and elongated tubular product container and having a second open end; extruding the chilled food product through an extrusion head mounted on a dispensing tube inserted into the food product through the open end of the bag said extrusion head having an extrusion head projection; avoiding softening of the chilled flowable food product after extrusion into a dispensing port by means of a heat sink created by the dispensing tube, connected extrusion head and extrusion head projection; and dispensing a uniformly chilled flowable food product.
