Specifications

evaporator is suitable to concentrating the liquid in traditional Chinese medicine, Western medicine, glucose, starch, etc.

 

Double-effect concentrator/ evaporator

 

 

1. Application

This concentrator is suitable to concentrating the liquid in traditional Chinese medicine, Western medicine, glucose, starch, monosidum glutamate, dairy product, chemical industry, etc.

Especially, it is suitable for the low temperature vacuum concentration of heat sensitive materials.

 

 

 

 

2. Structure of Equipment

Double-effect concentrator is composed of two tubular heaters, two evaporation chambers, circulating tube, condenser, liquid receiver and other accessories.

 

3. Main features:

1,Energy-saving. Calculated based on type SJN-1000, it can save about 3500tons steam one year, 9 tons cooling water, 80000 kilowatt-hour, which is equivalent to about 20000 dollars. (compared with single-effect)

 

2,This concentrator adopts external heating natural circulation type and vacuum negative pressure evaporation type, which features rapid evaporation speed, high concentration ratio (about 1.2-1.35) (normally Chinese medical extract).

 

3,This concentrator adopts double effect evaporation simultaneously; second steam can be used well, which can save the steam boiler cost and energy consumption. Compared with single-effect concentrator, the energy consumption can be reduced by 50%. So, the energy-saving cost can recoup all the machine cost for you.

 

4,Multi-function operation: (1) it can be used to recovery the alcohol with 80% content; (2) Single-effect, double-effect can work together to collect the extract. (3) The feeding can be batch or continuous.

 

5,With the special structure, all the concentrated extract is of strong flavor and uniform paste. The liquid is concentrated under the sealing and foamless state without any leakage and less of pollution. Moreover, the material is not easy of coking; it is easy of cleaning and operation.

 

6,All the parts contacting with materials are made of SUS304 stainless steel. There are heat insulation layers covering the outer of heater and evaporator to protect operators.
