Extraction concentratorproduct overview

The main feature is a dual effect concentration evaporator consisting of a single effect evaporator (vacuum external circulation can produce extracts with a specific gravity of 1.2 or less) and a combined concentration pot (vacuum external circulation and sandwich pot combination can produce extracts with a specific gravity of 1.4 or less). Different from the universal dual effect. The product is mainly suitable for concentration production processes in industries such as traditional Chinese medicine, health products, natural seasonings, food additives, food, and chemical engineering. It can provide extracts with different densities for different drying production methods, with a wide range of applications, easy operation, and low maintenance rate.

Extraction concentratorProduct Features

Under the same preheating steam pressure, during vacuum evaporation, the boiling point of the solution is small, and an increase in heat transfer temperature difference can correspondingly reduce the heat transfer area of the evaporator;

Can evaporate solutions that are not resistant to high temperatures, especially suitable for the evaporation of thermosensitive liquids in food production;

Low pressure steam or waste steam can be used as heating agents;

Low operating temperature and minimal heat loss;

Heating and sterilizing the liquid material is beneficial for food preservation.

Working principle

This utility model relates to a new device for the production of traditional Chinese medicine, food, health products, and chemical industry. It consists of a first effect tube heater, an evaporation chamber, a second effect tube heater, a concentration pot, a condenser cooler, a vacuum solvent recovery tank, and (plate heat exchanger, vacuum buffer tank).

The equipment connection is made by connecting the secondary steam port of the first effect external circulation concentrator to the second effect heating chamber and the condenser through pneumatic valves. Different production methods (dual effect or single effect) are adopted according to different production scales and requirements.

During dual effect production, the secondary steam from the first effect (with a vacuum degree of 0.04 Mpa and a liquid temperature of over 80 degrees) is used to supply the second effect concentration heating (with a vacuum degree of 0.08 Mpa and a liquid temperature of over 60 degrees). It can be used to produce high specific gravity paste according to requirements. When the first effect production paste has a specific gravity of around 1.2, it can be stored in the second effect combined concentration and further concentrated to reach around 1.4, and the paste can be produced. It can fully achieve energy-saving effects during the production process. Utilizing the advantages of short production time, fast speed, and easy operation in single effect single unit production, and effectively utilizing energy (single effect is better when the extraction liquid temperature is around 90 degrees, the concentration vacuum degree is -0.08Mpa, and the boiling point temperature is 60 degrees), can fully alleviate the urgent production needs. The large area of the condenser cooler can be used for single effect or combined concentration production in a single unit. Simultaneous production in two units is single effect production. If the solvent is recovered, it can be operated through the plate buffer tank in the vacuum protection system

Extraction concentratorapplication
