Introduction to the basic knowledge of extraction and concentration equipment

The extraction and concentration equipment is mainly suitable for the extraction and concentration of materials such as juice and the recovery of organic solvents.

Extraction and concentration equipment types: concentration tank, multi-function scraper concentration tank, rotary thin film evaporator, single-effect, multi-effect rising film or falling film evaporator, external circulation one-effect, two-effect, three-effect evaporator, forced circulation Evaporator.

Multi-functional extraction tank: This device can be used in traditional Chinese medicine as well as food, biological, chemical and other industries for water decoction, warm immersion, heat reflux, seepage extraction, aromatic component extraction, residue organic solvent recovery, and can also constitute forced circulation extraction, tank group A variety of operating processes such as countercurrent extraction. The unit can be operated under normal pressure conditions or under vacuum conditions.

Vacuum decompression concentration tank: is a jacketed concentration tank operated under a vacuum system. It is a series of products improved by the company's experience in the use of similar equipment in the country and the defects in the original design, with the cooperation of scientific research and design units in Shanghai and Jiangsu.

ZN-C type is an improved type based on ZN type. It is a universal evaporation device, which can be widely used in the evaporation, concentration of water, alcohol or other organic solvent liquid in pharmaceutical, food, chemical, light industry and other industries. . The device is suitable for hot reflux extraction of Chinese medicine, concentration, alcohol distillation and alcohol recovery of dregs, etc., and can be used in one can.

Multi-function scraper concentration tank: This equipment is a general equipment for food, medicine, chemical industry, etc. It is mainly used for mixing and reacting solid-liquid, liquid-liquid, especially high-viscosity materials. The equipment mixing system is coaxial output, the two groups of stirring are rotating in the forward and reverse directions, and because of its unique blade design, especially in the condition that the material viscosity is relatively large, the mixing and reaction of the materials are insufficient, and the material holds the shaft. And the problems of material sticking walls will be solved.

Extraction and concentration equipment structural features:

A. In order to prevent the material from being contaminated, all parts in contact with the material are made of stainless steel;

B. In order to improve the effect of vapor-liquid separation and trapping of mist, ZN type is to add a gas filter type filter layer on the top of the concentration tank. ZN-C type is an extended cylinder separation section;

C. In order to overcome the disadvantage that the secondary steam of the top of the concentrating tank is condensed before entering the condenser and returned to the tank. This equipment changes the condenser to a horizontal and horizontal type;

D. In order to improve the production capacity of the equipment, the heating area of ​​the concentrating tank jacket, the area of ​​condensation and cooler are increased to different extents;

E. In order to prevent the dead-end tank from producing a dead angle, the bottom of the concentrated tank is changed to a cone bottom, and the stainless steel spherical cork is directly mounted on the bottom of the tank to facilitate the discharge of the concentrated liquid;

F. A quick-opening hand hole is arranged in the lower part of the concentration tank to clean the residual liquid in the tank, and the residue
