Principle
The multi effect evaporation device uses the new steam to heat into the primary effect, and the generated secondary steam enters into the secondary effect for compound utilization, so as to further utilize the heat energy. The feed liquid is heated, evaporated and concentrated in multiple stages on the tube side, so as to reduce the running cost
Applications
Evaporation and concentration of traditional Chinese medicine, western medicine, glucose, environmental protection, dairy products, chemical industry, industrial wastewater and other solutions, especially suitable for operation under low temperature conditions.
Features
Remarkable energy-saving benefits: compared with single effect external circulation evaporator, the 1000 model saves 5400 tons of steam, 140000 tons of water and 130000 kilowatt hours of electricity a year.
With the combination of external heating natural circulation and negative pressure evaporation, the evaporation speed is fast and the concentration ratio is large, up to 1.2-1.3.
The three effect simultaneous evaporation is adopted, and the secondary steam is reused, which not only saves the investment of the boiler, but also saves the energy consumption. Compared with the single effect concentrator, the energy consumption is reduced by 70%.
Multi function operation features: (1) one effect, two effect and three effect can be used repeatedly to collect the paste in the pot; (2) intermittent and continuous feeding; (3) The concentrated mother liquor can be directly dried into solid through a complete set of equipment.
The parts in contact with materials are made of high-quality stainless steel, which conforms to GMP standards. The heater and evaporator of the equipment are equipped with insulation layer, and the surface of the insulation layer is made of stainless steel plate.
