The working principle of the double-effect energy-saving concentrator

The present invention double-effect energy-saving concentrator involves a new device
for the production of traditional Chinese medicine, food, health care products, chemical industry.
It is composed
of a one-effect tube heater, an evaporation chamber, a two-effect tube heater, a concentration pot, a condensation cooler, a vacuum solvent recovery tank, and a (plate heat exchanger, vacuum buffer tank).
The double-effect energy-saving concentrator equipment connection is made of the secondary steam port of the one-effect external circulation concentration pot through the pneumatic valve to connect the two-effect heating chamber and the condensing cooler respectively, and different production methods (double-effect or single-effect)
are adopted according to the different scale and requirements of production 。 In the dual-effect production (vacuum degree 0.
04Mpa, liquid temperature more than 80 degrees) one-effect secondary steam supply two-effect concentration heating (vacuum degree 0.
08Mpa, liquid temperature of more than 60 degrees), according to the requirements in the production of large specific gravity extraction: the specific gravity of the production of extract is about 1.
2 and can be concentrated in the two-effect combination concentration can reach about 1.
4 when the paste, in the production process to fully achieve the role of
energy saving 。 In the single-effect single production using the advantages of short production time, fast speed and simple operation, the advantages of single effect can alleviate the urgent need for production by giving full play to the advantages of single effect by making effective use of energy (when the extraction liquid temperature is about 90 degrees Celsius, the boiling point temperature is 60 degrees when the
boiling point temperature is 60 degrees Celsius*).
The large area of the condensing cooler can be used for single-effect or combined concentrated single production, and in two simultaneous productions is a single-effect production, if the recovery of the solvent can be operated
by the plate buffer tank in the vacuum protection system.
