A high capacity, continuous production blast freezer includes an insulated enclosure (10) and a plurality of adjustable product-carrying trolleys (20), individually moveable with the enclosure from an entrance location (12) to a n exit location (14). A heat exchanger in the form of an evaporator is provide d in the enclosure. The mechanical equipment for the refrigeration system can be placed within the enclosure and separated from the freezing cell by a bulkhead. In one embodiment the enclosure is in the form of a container adapted to be transported by ship, rail or truck. The arrangement of the hea t exchanger or evaporator relative to the product carrying devices and the enclosure is designed to maximize the capacity of the heat exchanger and minimize frost formation, while providing for a maximum amount of product space within the enclosure to maximize throughput of the system.
