Description of Low Temperature Evaporator Vacuum Evaporator Falling Film Evaporator
According to customer requirements, we have developed the double-effect energy saving concentrator with single-effect ointment collection. During normal concentration, the valves connecting the spraying tube with circulating tube in the first-effect heating chamber and evaporating chamber will be closed. The materials will enter into the first -effect evaporation chamber and through the jacket heating in the first-effect evaporation chamber, normal pressure type or pressure relief type concentration will be carried out in the first-effect evaporation chamber so as to obtain ointments of relatively high concentration ratio (1.35~1.45).
Main Features
1. The first-effect and second-effect evaporation ratio is 1.1/1, the steam consumption and evaporation ratio is 0.55/1, so that secondary steam is fully utilized, saving both steam and cooling water circulation volume.
2. The equipment adopts external heating natural circulation mode and vacuum negative pressure evaporation mode, with instant evaporation and great concentration ratio up to 1.1~1.3. The liquid materials are concentrated without foam under the completely sealed status. The liquid medicines concentrated from the equipment have no pollution and have strong medicine flavor. The cleaning is convenient (Just open the upper cover of the heater).
3. Energy saving benefit. Taking JIN1000 model for calculation, approximately 3500 tons of steam, 90000 tons of cooling water and 80000 electrical degrees can be saved in a year, and thus the costs of nearly RMB 100000~150000 are reduced (compared with single effect of the same specification).
