Screw Heat Exchangers
If you are you seeking a continuous method of heating or cooling powders or granules, then a brand new product to Orthos – and the UK – might be of interest: the °Celsius screw heat exchanger.
Heat transfer takes place via screw shaft, jacket, flights or a combination of all. Available in a range of versions to suit any application, the °Celsius machine may have single or twin screws running in a trough or tube style housing, fabricated in mild or stainless steel.
Cooling can be done indirectly to a product temperature of -25°C, or with direct cooling -196°C.
Heating can be done indirectly with water (up to 160°C), thermal oil (up to 300°C) and steam (up to 200°C).
Typical applications: Cooling cocoa press cake, defrosting fruit berries, heating calcium carbonate, drying egg shells, cooling starch powder.
