Shock refrigeration is an integral part of the production of semi-finished products - produced semi-finished products must be frozen as soon as possible to the temperature appropriate for prepackaging. As soon the production is frozen, its quality improves after defrosting, because the correct ice crystals are being formed. Also there is less loss of weight due to the lower assimilated moisture content. But the most important thing is that it is not necessary to stop the production line while waiting for the production is frozen in a usual freezer. We are engaged in design and installation of fast-shock cooling and freezing chambers of different operating power and purpose.
