summary:

Single effect external circulation vacuum concentrator, composed of heater, evaporator, demister, condenser, cooler, liquid receiving tank, etc. All parts in contact with materials are made of high-quality stainless steel. This equipment The concentration time is short, the evaporation rate is fast, and the thermosensitive material can be well maintained without damage. Suitable for evaporation and concentration of liquid materials and industrial organic solvents in industries such as pharmaceuticals, food, chemical, and light industry The recycling of (such as alcohol).

There are three types of single effect evaporators:

1. The WZ single effect external circulation vacuum concentrator is a common type used for the evaporation of aqueous solutions. 2. WZH single effect external circulation vacuum concentration and recovery device is an alcohol recovery type used for the evaporation of alcohol solutions. It has a large condensation cooling area to ensure alcohol recovery, with a recovery concentration of 70-85% The loss rate is less than 5%, and the temperature after alcohol recovery is less than 40 ℃. 3. WZS single effect external circulation vacuum concentration collector, used for single effect evaporation and concentration of paste. After normal single effect evaporation, close the valves connecting the heating chamber and evaporation chamber to the nozzle and circulation pipe, and allow the liquid to flow All of them enter the evaporation chamber and are heated by the jacket of the evaporation chamber for atmospheric pressure reduction concentration, increasing the concentration density of the material to 1.2-1.3.

Equipment features 1. Alcohol recovery: With high recovery capacity, it adopts a vacuum concentration process. Compared to similar older equipment, it increases productivity by 5-10 times, reduces energy consumption by 30%, and has the characteristics of low investment and high recycling efficiency. 2. Concentrated liquid material: This equipment adopts external heating natural circulation and vacuum negative pressure evaporation methods, with fast evaporation speed and a concentration density of up to 1.3; The liquid material has no foam concentration in the fully sealed state, The concentrated medicinal solution produced by this device has the characteristics of no pollution, strong medicinal taste, and easy cleaning (by opening the upper and lower covers of the heater for cleaning). This device is easy to operate and occupies a small area The heater and evaporator adopt stainless steel insulation structure, and the insulation is made of polyurethane foam. The outer surface is frosted and matte treated, which meets GMP pharmaceutical standards.
