Characteristics of vacuum pressure reducing concentrator

　　Vacuum pressure reducing concentratoroperation

The vacuum pressure reducing concentrator uses vacuum feeding to add the feed liquid. First, turn on the vacuum pump and at the same time, open the feed valve to ensure that the liquid level in the tank does not exceed the sight glass on the tank body, in order to ensure a certain evaporation space and reduce the entrainment of mist. After closing the feeding valve, the jacket steam inlet valve can be opened to allow the material liquid in the tank to adapt to boiling and start evaporating (the heated steam can only enter the jacket after being reduced to ≤ 1.5kg/cm2 by the pressure reducing valve). To accelerate the evaporation speed and reduce the evaporation temperature, pressure reduction concentration is used, and the vacuum degree is determined by the user according to different requirements. At the same time as opening the jacket steam valve, the cooling water inlet valve should be opened.

As the liquid inside the tank continues to evaporate, the liquid level drops. Therefore, continuous feeding can be used to ensure that the liquid level in the tank does not change. Intermittent feeding is also possible. Either way, the vacuum inside the tank can be used for feeding at any time during operation. After the operation is completed, manual operations such as opening the discharge port, slag outlet, and liquid outlet must be carried out only when the vacuum or negative pressure is eliminated (i.e. the vacuum pump stops, the valve on the exhaust pipe is opened, and there is no vacuum degree on the p1 and p2 vacuum gauges). The specific gravity of concentrated solution should not be greater than 1.2-1.25 for traditional Chinese medicine solution, otherwise it will bring certain difficulties in feeding and cleaning.

Characteristics of vacuum pressure reducing concentrator：

1. Alcohol recovery: With high recovery capacity, it adopts a vacuum concentration process. Compared to similar old equipment, it has increased by 5-10 times, reduced energy consumption by 30%, and has the characteristics of low investment and high recycling efficiency.

2. Concentrated liquid material: The vacuum pressure reducing concentrator 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 medicine liquid concentrated from the vacuum vacuum concentrator has the characteristics of no pollution, strong medicine taste, and easy cleaning (open the upper and lower covers of the heater to clean).

3. The vacuum pressure reducing concentrator 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 standards.

Characteristics of vacuum pressure reducing concentrator

Vacuum vacuum concentrator refers to equipment used in the concentration production process of traditional Chinese medicine, health products, natural seasonings, food additives, food, chemical and other industries. The vacuum vacuum vacuum concentrator is composed of five main parts: heating chamber, evaporation chamber, condenser, receiver, and cooler. Below, the manufacturer of the vacuum vacuum vacuum concentrator will provide you with a detailed introduction to the various components of the vacuum vacuum vacuum concentrator.

1. Heating chamber: composed of shell, heat exchange tubes, insulation layer, installation supports or legs, various process pipe openings, etc. The heating chamber of the vacuum pressure reducing concentrator is tubular, with double-layer insulation. The upper and lower parts are connected to the evaporation chamber through nozzle elbows, and the upper hole cover is used for cleaning the tubular.

2. Evaporation chamber: composed of inner cylinder, jacket (optional component), head, insulation layer, cladding, support feet (ears), manhole, sight glass and connecting pipe, various instruments, various process pipe openings, etc.

3. Condenser: The vacuum pressure reducing concentrator condenser consists of a shell, heat exchange tubes, a tube box, and various process pipe openings. Condense the steam from the self evaporating chamber and enter the cooler after condensation.

4. Receiver: The water receiver consists of two chambers, upper and lower. The liquid receiver is a double-layer structure with upper and lower layers, which recovers the cooled waste solvent.

5. Cooler: The cooler consists of a shell, heat exchange tubes, tube box, and various process pipe openings. The steam from the condenser of the vacuum pressure reducing concentrator is further condensed and discharged into the receiver after condensation.
