Direct Steam Sterilization
Concentrated food products need to be sterilized before they can be stored, packed or dried.

GEA has a wide range of experience in product sterilization by direct steam injection.
During the direct high-heating, steam is injected into the product by means of a DSI unit (DSI = direct steam injector). In this way, the product is suddenly heated and flashed against a low pressure after a very short holding period and in this way it is cooled again just as quickly.
This sterilization process shows significant advantages compared to an indirect high-heating by means of heat exchangers. In case of indirect high heating the holding time at high temperatures is much longer.The short retension time and the possibility to treat high viscous products are the main advantages of this technology.
Trocador de calor vertical tipo concha e tubo com tubo de pouco comprimento, com separador lateral disposto no topo.
Uma configuração de placa e estrutura emprega placas especiais, com produto e meio de aquecimento em canais alternados. As placas são seladas pelas juntas localizadas dentro de vãos especialmente projetados que não requerem adesivos. Estas juntas podem ser inseridas e removidas sem ferramentas especiais.
Vertical shell-and-tube heat exchanger, with a laterally or concentrically arranged centrifugal separator.
Horizontal or vertical shell-and-tube heat exchanger or plate heat exchanger as the calandria, with flash vessel/separator arranged above the calandria, circulation pump.
Disponibilidade para testes em plantas-piloto e em laboratório para diferentes tipos de sistemas de evaporação.
