Kärntnermilch, a big farmers' cooperative with over 3,000 members, operates a modern production plant in Spittal/Drau, Austria. Each year, the plant processes some 74 million liters of raw milk into yoghurt, cheese and other dairy products.
Demands
To allow the cooperative to environmentally friendly modernise and expand its existing production capacity a spiral freezer for cooling yoghurt using natural refrigerants was needed.
Solution
The KWN Engineering-Gesellschaft mbH planned an indirect plant with a compact set of refrigeration units. This marks the first time that an ammonia/dimethyl ether mixture is used as a refrigerant in Austria.
