In order keep the seafood or meat or beef or chicken and other meat, if want to long time store, we have to blast freeze them in -40ºC temperature in short several hours to frozen them, and then store them into freezer room for long time store (-18ºC~-25ºC), to balance the time of market, improve the economic performance.
Consider this situation, OnlyKem design a series regular deep freezer products, to suit the different cargo and customers's request.
Advantage of Blast Freezer Refrigeration Equipment Refrigerator Cold Room
1. Free money, ttrong power technical support, designing, drawing, trouble shooting, all service are FREE.
2. Automatical, One stop solution for blast freezer, Automatic control, no need you to do any manual action when operation.
3. Smart monitor system, can monitor the complete process, and will alarm reminder by SIM.
4. Power saving, each shift needs 250KW*H power sorce, 0.125kw*H per KG for freezing cost, economic.
PU Panel
Because the internal temperature of blast freezer room is low, we usually recommend using 150mm/200mm. Thicker external thermal insulation structure can reduce the loss of cold energy and reduce power consumption.
