Rotary Drum Freezer

The ReelFrez freezing system is a compact rotary drum freezer constructed of high-density polymer and stainless steel, insulated and sealed to prevent air infiltration. Food product is assembled on a conveyor system and enters the sealed rotating drum pockets. As the product is introduced into the pockets, it is immediately crust-frozen by immersion in a liquid bath of refrigerant agent. This crust of the liquid in the product is a crystalline structure that has formed a matrix to protect the delicate inner sections, which contain the meat, flavoring juices and aromas.

The liquid refrigerant is drained off as the drum rotates the food product remaining in the pockets for drying (evaporation of refrigerant). Rotation cycle is timed and synchronized to produce the level of product freezing desired. Food product is discharged from the rotating drum onto a conveyor system for packaging. The liquid freezant and vapor gas is recaptured and recycled.

The shape of the product is preserved during the quick freezing process, preventing damage during deep frozen storage. This surface also prevents sticking, ice-packing, or the formation of solid clumps of frozen products.

The system provides a method for freezing specialty products that are difficult to freeze employing conventional systems, including peeled and deveined shrimp (prawns), fish fillets, sauces (gravies) or other fragile food products. The system is marketed to those countries without a ban on the use of certain refrigerants.
