Fast freezing

Johnson Controls offers different technologies for fast freezing different kind of fish products. Depending on the requirements we can utilise immersion freezing and blast freezing or plate freezing.

		Immersion in low-temperature brine was one of the first methods used for quick-freezing fish products. Blast freezers for fishery products are generally small rooms or tunnels in which cold air is circulated by one or more fans over an evaporator and envelopes the product to be frozen, either on racks or shelves. In a plate freezer, refrigerant flows through connected passageways in horizontal movable plates stacked vertically in an insulated cabinet or room.

Cold-storage

Cold-storage facilities for fresh fish should be maintained at about 2°C with over 90% rh.

Air velocity should be limited to control ice loss. From the time the product is frozen until it reaches the consumer, frozen seafoods should be kept as close to –26°C as possible. In both cases high relative humidity in cold-storage rooms tends to reduce evaporation of moisture from the product. The evaporator coils in the freezer should be sized properly so that the desired high relative humidities can be obtained.
