This utility model relates to a new device for the production of traditional Chinese medicine, foodstuffs, health products and chemicals. It is composed of a first-effect tube heater, evaporation chamber, second-effect tube heater, concentration pot, condensation cooler, vacuum solvent recovery tank, (plate heat exchanger, vacuum buffer tank).
The equipment is connected by the secondary steam port of the first-effect external circulation concentration pot through a pneumatic valve to connect the second-effect heating chamber and condensation cooler, respectively, according to the production of different scales and requirements of different production methods (double-effect or single-effect).
In the double-effect production (vacuum degree 0.04Mpa, liquid temperature 80 degrees) the use of a second effect of the steam supply two-effect concentration heating (vacuum degree 0.08Mpa, liquid temperature 60 degrees), according to the requirements of the production of a large specific gravity of the paste: a production of a specific gravity of the paste in the production of the specific gravity of the paste in 1.2 or so, and tanks in the two-effect combination of concentration to continue to concentrate to reach about 1.4 paste in the production process using it to fully achieve energy-saving, the production of a combination of the paste in the production process. In the production process, it is used to fully achieve the role of energy saving. In the single-effect single production, the use of single-effect production time is short, fast, easy to operate the advantages of the effective use of energy (extract temperature at about 90 degrees when the concentration of vacuum at -0.08Mpa when the boiling temperature of 60 degrees using a single-effect for the best) to give full play to the advantages of the single-effect can alleviate the production of the urgent need. The use of condensing cooler area can be single-effect or combined concentration of a single production, in two separate simultaneous production is the production of single-effect, such as if the recovery of solvents can be operated through the vacuum protection system in the plate buffer tank.
