News from demonstrator 18: Blast freezing
The demonstrator is an ultra-low temperature CO2 direct expansion unit for food blast freezing, to be used in freezing tunnels, conveyors, spirals, etc. Fast freezing is assured by extremely low evaporation temperatures (close to -50 °C) and high air volume flow. State-of-the-art technologies are applied for optimal use of the heat transfer surface, capacity control,…
