Abstract: A hose fitting assembly for connecting to a food mix bag of a frozen food dispensing machine is provided. The hose fitting assembly includes a fitting body defining a hollow fitting body interior. Also included is a probe cap repeatedly matable with the fitting body and having an inner wall defining a hollow probe cap interior.

Abstract: A method of making a heat exchanger includes providing an inner tube extending longitudinally along a central axis and having an inner surface bounding a product chamber and an outer surface. An outer tube is formed and positioned about the inner tube. The outer tube is disposed coaxially about and circumscribing the inner tube in a radially spaced relationship. Forming the outer tube and positioning the outer tube about the inner tube occur simultaneously.

Abstract: A seal assembly including at least one conduit configured to allow a medium to flow therethrough, an annular retaining means operably coupled to the conduit, and an annular resilient seal member disposed in the annular retaining means. A method of sealing a dispensing system containing a food product creating a food product pressure, wherein the dispensing systems includes a drive shaft operably coupled to a seal assembly, the seal assembly including an annular resilient seal member disposed in an annular retaining member, the annular retaining member being operably coupled to at least one conduit, the method including the steps of: dispensing a medium through the at least one conduit to enter the annular resilient seal member to create a seal pressure greater than or equal to the food product pressure.
