Blast-freezer is an automated system for cooling, freezing and shock-freezing, to rapidly bring the temperature of foods down. Blast freezers operate with blowers which force chilled air over the food in the freezer to cool it down rapidly. The main feature is that product can be frozen without being damaged, while maintaining good taste and appearance.

In a blast freezer, extremely cold temperature provides rapid freezing, which creates small ice crystals. The smaller the crystal, the less damage it does, as large crystals can rupture product’s cells and structure. Once food had been frozen, it can be moved to conventional freezer for further storage, as long as the freezer stays cold enough to keep the food frozen.

Area of application:

  • Blast-freezer creates a frozen layer up to 10-1 mm around the product.
  • Short-term freezing of various products just before packing.
  • To increase the shelf life of a product
  • To freeze any product without changing its original appearance (shape, color, taste)

Blast freezer is usually used as part of production line. This equipment can freeze large products, for example sturgeon and salmon. High speed of freezing allows to reduce occupied space and place production lines on ships or in small buildings.

We produce only energy-efficient blast-freezers, based on eco-friendly refrigerants CO2 and NH3.
