Dampfstrahlvakuumpumpen in der Speiseöl-Industrie Auslegungsmerkmale und Betriebsverhalten

Steam Jet Vacuum Pumps in the Edible Oil Industry – Layout Characteristics and Operational Behaviour For vacuum generation in distillation and deodorization multiple stage steam jet vacuum pumps are preferred in conjunction with mixed condensers. The working range of the steam jet pump should be adapted to the various materials processed and the cooling water available, and, a minimum of energy requirement should be aimed. The relevant considerations are presented in the form of diagrams and layout plans. The unavoidable mixing of suction current, ejector current and cooling water and its consequence on the waste water pollution are discussed.
