Cooling and Freezing

Economic and ecological freezing with cryogenic gases

GAS APPLICATION

Although freezing is by far the best preservation method for food, improperly slow freezing or an unsteady temperature drop in the product can lead to formation of large ice crystals and damage to the cell walls e.g. for fruit. The food then loses a part of the cell liquid content during later defrosting and thus suffers loss in nutritional value, taste and consistency.

 

A high freezing rate of more than 5 cm/h is achieved with liquid nitrogen (LN2) or liquid carbon dioxide (LCO2) as a freezing medium, so that the cell structure of the frozen food is preserved through the fine-crystalline freezing of the water portion. This means that after defrosting no losses in cell liquid content occur. A further advantage is the prevention of dehydration and thus undesirable weight loss during the freezing process through rapid freezing of the product surface.   

Advantages:

Higher product turnover through short freezing times
High quality of frozen products
No dehydration losses
Fast operation through rapid cooling of plants
Low investment costs
Takes up little space
High plant
Low maintenance and repair costs (simple plant construction)
