Working principle and characteristics of double effect energy saving concentrator

The utility model relates to a new device for the production of traditional Chinese medicine, food, health care products and chemical industry The utility model is composed of a first effect tube heater, an evaporation chamber, a second effect tube heater, a concentration pot, a condensation cooler, a vacuum solvent recovery tank, (a plate heat exchanger, a vacuum buffer tank) Equipment connection is that the secondary steam port of the primary external circulation thickener is connected with the secondary heating chamber and the condenser cooler respectively through the pneumatic valve, and different production methods (double effect or single effect) are adopted according to different production scales and requirements 　　 In the double effect production (vacuum degree 0.04MPa, liquid temperature more than 80 degrees), the secondary steam of the primary effect is used to supply the secondary effect concentration heating (vacuum degree 0.08mpa, liquid temperature more than 60 degrees) According to the requirements, in the production of large specific gravity extract, when the proportion of the primary effect production extract is about 1.2 and can be concentrated continuously in the secondary effect combination type, it can reach about 1.4 to produce the extract It is fully used in the production process To achieve the role of energy saving The advantages of single effect, such as short production time, fast speed and simple operation, can be used in single effect and single unit production The urgent need for production can be alleviated by making full use of the advantages of single effect and single unit production, such as the effective use of energy (the concentration vacuum at about 90 degrees and the boiling point at - 0.08mpa and Zui at 60 degrees) Using the large area of the condensing cooler, single effect or combined concentration can be carried out in a single production The production of two condensing coolers at the same time is single effect If the recovered solvent can be operated through the plate buffer tank in the vacuum protection system Features 1 The condenser is equipped with large size and good recovery effect 2 According to the production requirements, it can be divided into two single effect and combined equipment with different production modes for concentration 3 The production scale can be large or small, and the single effect evaporation capacity of the decomposed two units is 2.5 times of that of the double effect evaporation 4 It can save money and energy for users and fully meet the "GMP" standard The utility model relates to a traditional Chinese medicine production device It is mainly characterized by a double effect concentration evaporator composed of a single effect evaporator (extract with a specific gravity of less than 1.2 can be produced by vacuum external circulation) and a combined concentration pot (extract with a specific gravity of less than 1.4 can be produced by vacuum external circulation and mezzanine pot combination) Different from the general double effect.
