Process Brief: Food products are frozen by direct contact with a chilled surface

 

Energy source: Electricity/ some Natural Gas

 

Energy Intensity: 250-1,700 Btu/lb of product

 

Plate freezers are useful for freezing fish, pieces of poultry and cartons of vegetables. Direct contact cooling with a stainless steel plate chills the product at a faster rate than chilled air. The plates may be arranged vertically or horizontally. A typical installation has 15-20 sets of plates that are loaded and unloaded automatically. Vertical plate freezers have been specially designed to freeze fish at sea, creating blocks of frozen fish that are 20-30 pounds each. A major advantage of plate freezers is compact size and the ability to quickly freeze large products.

 

The heat transfer rate for plate freezers is much higher than chilled air freezers and comparable to fluidized bed freezers. A two-pound carton of vegetables can be frozen in 25 minutes and a 50-pound block of fish can be frozen in 75 minutes. One advantage of plate freezers is that temperature sensors on the plates can track the surface temperature of the product, which can aid process control.
