The superb conductivity of a steel belt combined with its excellent mechanical properties at low temperatures makes it an exceptionally efficient medium on which to freeze a range of products, including instant coffee.
After roasting, the coffee is milled, turned into a slurry and deposited onto a continuously running steel belt that travels through the freezer. The frozen material is then broken up, milled and dried, leaving behind pure coffee extract.
The hard, flat, smooth surface of a steel belt ensures easy product release at the end of the freezer, while also making it easy and economical to clean, enabling the highest standards of hygiene to be maintained.
The coffee freezer enables smooth, temperature-controlled freezing to maintain the colour and flavour of the coffee.
