In double-effect production (vacuum degree of 0.4 when the extract is produced. The equipment connection is the second-effect heating chamber and the condensing cooler through the secondary steam port of the first-effect external circulation concentrator through the pneumatic valve separation. When two separate sets are produced together, it is a single-effect production.08Mpa, liquid temperature of over 60 degrees), which can be used in large-scale production according to requirements Specific gravity extract: when the specific gravity of the first-effect extract is about 1. The large area of the condensing cooler can be used for single-effect or combined concentrated single-stage production. It is useful to use the power (when the temperature of the extract is about 90 degrees, the vacuum degree of concentration is -0.2 and can be combined in the second-effect combined type concentration, the extract can reach about 1. According to the different production plans and requirements, different production methods are selected ( Double effect or single effect). (Effect is the best) Full play to the advantages of single effect can alleviate the urgent need for production.08Mpa, and the boiling point temperature is 60 degrees. It is not only used in the production of food additives, food, etc., but also in traditional Chinese medicine, health care products, natural seasonings, and chemical industries. The utility model of the double-effect energy-saving concentrator touches a new device stainless steel Bright beer tanks produced in Chinese medicine, food, health care products, and chemical industry.04Mpa, liquid temperature of over 80 degrees), one-effect secondary steam is used to supply two-effect concentration heating (vacuum degree of 0.. It is used in the production process to achieve the effect of energy saving. It is composed of a single-effect tube heater, a transpiration chamber, a second-effect tube heater, a condensing pot, a condenser cooler, a vacuum solvent recovery tank, (plate heat exchanger, vacuum buffer tank). If the solvent is recovered, it can be operated through the plate buffer tank in the vacuum maintenance system. Introduction to the operating principle of the double-effect energy-saving concentrator. Concentrator has a wide range of applications. It can supply extracts with different proportions for different boring production methods, with wide application, simple operation and low repair rate. In the single-effect single production, the single-effect production time is short, the speed is fast, and the operation is simple
