In the food industry, in the organic and chemical industry, and for wastewater treatment.
Some advantages of the rising-film SIGMASTAR®.
Superior product distribution due to the thermo-siphon principle. As product boils and rises in the tube, fresh product automatically rises to refill the tube. This distribution technique operates independently of the feed rate, allows a high degree of flexibility and the possibility of turn down.
Very short residence time; the product is in the SIGMASTAR® for less than a second. This is due to the short flow distance and the high product film velocity. This feature guarantees a gentle treatment of the product.
Low pressure losses across the tubes, a benefit of the short tube length.
High vapour velocity in the rising film, which allows the processor to achieve high concentrations and viscosity.
Clearly defined product flow path. There is no chance of local over-concentration.
High heat transfer co-efficients are obtained even when the feed temperature is lower than the boiling temperature.
Compared to other evaporizer systems less expensive for high grade materials of construction.
Easy assembly and dismantling. A change in the size of the heat exchange surface by varying the number of heat exchange plates makes it possible to create more compact systems.
