Abstract : Techniques of freezing vary for each application, The type of refrigeration used for preserving fruits cannot suit the need of the fish industries.
Later it has been discovered that the number of viable vegetative microorganisms in food are usually greatly reduced by freezing if quick freezing is employed.
The conventional freezers could not cope with this higher rate of freezing. By the development of the plate freezer, the challenge of quick freezing has been met to enhance effective preservation.
Plate type evaporators may be used in single or in banks. The plates may be manifolds for parallel flow of the refrigerant or they may be connected for series flow.
Plate evaporators are especially useful used for liquid cooling installation where unusual peak load conditions are encountered periodically.
