It is used in the production process to fully achieve the effect of energy saving. In single-effect single-unit production, the advantages of single-effect production time, fast speed, and easy operation are used to effectively use energy (when the temperature of the extract is around 90 degrees, the concentration vacuum is -0.08Mpa, and the boiling point temperature is 60 degrees. Effectiveness is the best) Give full play to the advantages of single effect can alleviate the urgent production needs. The large area of the condensing cooler can be used for single-effect or combined concentration single-effect production. Two sets of simultaneous production are single-effect production. If the solvent is recovered, it can be operated through the plate buffer tank in the vacuum protection system. The products are mainly adapted to the concentrated production process of traditional Chinese medicine, health care products, natural seasonings, food additives, food, chemical industry and other industries. It can provide extracts with different specific gravity for different dry production methods, with wide application area, simple operation and low maintenance rate.
