Brand: Air Liquide

Video about the cooperation with Air Liquide:

Technical Specifications

• Tunnel freezer, cryogenic system: coolant N2 (with a boiling point at -196 ° C), is sprayed directly on the products in the tunnel
• The tunnel contains 3 zones with nozzles for spraying the coolant
• Conveyor length 5 m, width 0.6 m
• Adjustable conveyor speed determines the residence time, often about a few minutes
• Tunnel temperature adjustable from -40 ° C to -120 ° C. Temperature control by means of ventilation and gas inlet

Scope

• Cryogenic cooling and freezing allows the temperature to drop quickly

Application for:

• Making IQF products (individually quick frozen products) such as peas, strawberries, ham cubes
• Not damaging cell structures, to maintain texture with meat, vegetables, fruits and prepared meals
• Crust freezing, by freezing only the product surface, to maintain shape (with corrugated ice cream), avoid moisture loss (with meat) and finer slicing (salami or cake).
• Better hygiene through faster inhibition of growth micro-organisms
