Abstract
An improved refrigerated mixing chamber for the food and beverage industry and associated method of manufacture is provided. The chamber is manufactured from a pre-formed piece of stainless steel that has been cold pressed into shape so that it has no axial welds. The device further includes an outer sleeve that is shrink fitted around the chamber. The sleeve has an advancing helically groove formed on its inside surface. The combination of the helical groove and the outer surface of the chamber forms a helical passageway through which refrigerant flows. The method of manufacture causes the grooves in the outer sleeve to interfere with the outer surface of the chamber such that an advancing helical rib is formed around the chamber. This rib aids in strengthening the chamber.
Claims10
A refrigerated chamber system, comprising:
- (a) a cylindrically-shaped seamless inner chamber having an advancing helically-shaped rib formed around its circumferential surface for strengthening said inner chamber, said inner chamber being adapted to contain a product to be cooled therein;
- and
- (b) a cylindrically-shaped outer sleeve axially disposed over the inner chamber, the outer sleeve having an advancing helical groove formed on its inner circumferential surface, the helical groove and the outer surface of the inner chamber forming a passageway through which a refrigerant passes which cools the product contained within the inner chamber.
