Abstract

A freezing apparatus is disclosed wherein a first and a second endless belt conveyor are disposed substantially horizontally put one upon another with a predetermined gap being left between the confronting runs of the conveyors, the conveyor belts being adapted to be separately cooled at their rear surfaces by means of cooled brine, and adapted so that products-to-be-frozen can be supplied into the gap from one end with their upper and lower surfaces being kept in contact with the exterior surfaces of the confronting runs of the moving belts to be conveyed towards the other end of the gap, whereby the products are quickly frozen by simultaneous cooling of their upper and lower surfaces. In this case, at least one of the belt conveyors is preferably composed of a flexible belt conveyor made of e.g. a thin rubber sheet.
