Briefly describe the use and working principle of double-effect energy-saving concentrator

<br> <br> use double-effect energy-saving energy-saving double-effect concentrator concentrator is mainly suitable for traditional Chinese medicine, health care products, natural spices, food additives, food and chemical industries concentrated production process. It can provide different proportions of extracts for different drying production methods, which is applicable to a wide range of applications, simple operation and low maintenance rate. Concentrator features:

1. The condensing cooler has a large configuration and good recovery effect.

2, according to the production needs can be double-effect and can be decomposed into two different production methods of single-effect and combined equipment for concentration.

3. The production scale can be large or small, and the two single-effect evaporation capacities after decomposition are 2.5 times that of double-effect evaporation.

4. It can save users money and save energy, and fully meet the "GMP" standard.

The utility model relates to a traditional Chinese medicine production device. The main feature is a double-effect concentrated evaporation consisting of a single-effect evaporator (vacuum external circulation can produce an extract with a specific gravity of 1.2 or less) and a combined concentrating pot (a vacuum external circulation and a sandwich pot combination can produce an extract having a specific gravity of 1.4 or less). Device. Different from the universal double effect.

Working principle of double-effect energy-saving concentrator The utility model relates to a new device for traditional Chinese medicine, food, health care products and chemical production. It is composed of a one-effect tube heater, an evaporation chamber, a two-effect tube heater, a concentrating pot, a condensing cooler, a vacuum solvent recovery tank, a (plate heat exchanger, a vacuum buffer tank).

The equipment connection is connected to the secondary effect heating chamber and the condensing cooler through the pneumatic steam valve by the secondary steam port of the first-effect external circulation concentrating pot, and different production methods (double effect or single effect) are adopted according to different scales and requirements of the production.

In the double-effect production, the secondary steam supply with a vacuum of 0.04Mpa and a liquid chemical temperature of more than 80 degrees is used for secondary effect heating (vacuum degree 0.08Mpa, liquid temperature more than 60 degrees), which can be produced according to requirements. When the specific gravity of the extract is: the specific gravity of the production of the extract is about 1.2, and the can is concentrated in the second-effect combined concentration and can reach the concentration of about 1.4. The paste is used in the production process to fully achieve the energy-saving effect. In the single-effect single-stage production, the single-effect production time is short, the speed is fast, and the operation is simple, and the energy is effectively utilized. (The concentration of the extraction liquid is about 90 degrees, and the concentration of the vacuum is -0.08Mpa, the boiling point temperature is 60 degrees. The effect is Zui Jia) to give full play to the advantages of single effect can alleviate the urgent need for production. The single-effect or combined-concentration single-stage production can be carried out by using a large area of ​​the condensing cooler, and the simultaneous production of the two units is a single-effect production, and if the recovered solvent can be operated by a plate buffer tank in the vacuum protection system.
