A shell freezer for the freezing of liquids in a container in a uniform layer on the interior walls of the container having belts rotating over rollers within a bath; rods are secured over the belts to act as stops for cylindrical containers placed on the belts, thereby causing the rotation of the containers. Underneath the rotating belt is a supportive platen which is covered with a fabric to allow smooth rotation of the belt while supporting a flask full of liquid. The bath may be tilted to a desired angle to allow more liquid to be frozen within a container. A novel heat exchanger cools the thermal transfer fluid which is circulated over the belts and back to the heat exchanger, to allow a minimum of such fluid in use.

A shell freezer for the freezing of liquids in containers, said liquids freezing in a substantially uniform manner on the interior walls of the containers, said freezer comprising a bath, a rotating endles belt assembly within said bath, said containers being supported by and rotating on said endless belt assembly, thermal transfer fluid circulating within said bath across said endless belt assembly thereby contacting said rotating containers and freezing the liquid contents of said containers about its interior in a uniform manner, said bath including rods selectively positioned above said belts in a plane transverse to the plane of rotation of said belts, said rods providing a stop against which containers may rotate, said stops retaining said containers for rotation on said belt in a desired position within said bath.
