Evaporation is for the purpose of the moisture evaporation of thin adhesive solution escape, so that the glue liquid is condensed, facilitate gelatin cooling molding and dry.
The fluid gelatin solution is heat-sensitive, if under atmospheric pressure boiling evaporation, is bound to produce secondary hydrolysis reaction has been described, which will greatly reduce the quality of the gelatin. Therefore, gelatin solution evaporation adopts vacuum evaporation, in order to reduce the evaporation temperature.
Gelatin evaporator must meet the following requirements:
1. The evaporation temperature is lower
2. The gelatin solution and heater heating surface contact time is shorter
3. Especially under the condition of low solid content in gelatin solution, can inhibit formation of latex foam.
4. Save energy consumption.
The company design and manufacture of gelatin dedicated evaporation concentrator, through long time practice experience combined with physical and chemical properties of gelatin, well meet the evaporation and concentration of gelatin production technology on the gelatin requirements; Original heat exchange design; High concentration ratio, high thermal efficiency; Have a number of independent intellectual property rights. The company design and manufacture of the evaporator are: single effect evaporation concentrator, 2 -- 5 effect evaporation concentrator, a rising membrane type and the falling film type, PLC control, well meet the needs of the market at home and abroad.
