Chinese medicine multi-function extraction tank has to say the advantages of the characteristics

The multi-functional extraction tank of traditional Chinese medicine is a commonly used leaching extraction equipment in medicine and chemical industry, and is particularly suitable for leaching extraction of components contained in plant products. In the Chinese medicine factory, the extraction tank is used as a multi-purpose equipment designed for cooking and extraction, and has an irreplaceable role. The extraction tank integrates multi-function extraction, vacuum concentration and solvent recovery, simplifying the operation procedure. Traditional Chinese medicine multi-functional extraction tanks are used for the extraction, concentration and recovery of organic solvents in Chinese herbal medicines, fruit juices, etc. in hospitals, pharmaceutical factories and food industries. The multi-functional extraction tank of traditional Chinese medicine can also be used in colleges and universities, scientific research institutions, hospitals, etc. as new drug extraction, determination of technical parameters of new processes, intermediate tests, development of new varieties, extraction of valuable herbs, recovery of volatile oils and concentration of liquids. The equipment has high extraction efficiency for active ingredients of large quantities of medicinal materials, saves energy, and extracts more effective extracts with higher concentration of extracts, which is widely used in the development of Chinese medicine industry.

Main structural features of multi-function extraction tank:

1. Heating form: the jacket is heated, and no heat source at the bottom forms a heating dead angle.

2, extraction efficiency: static heating mode, because the bottom of the heat source does not form a heating dead angle, so that the bottom medicine is not completely extracted. The floating herbs (slowly immersed in the extract after boiling) are not completely extracted from other herbs. Equipment structure issues reduce extraction efficiency.

3, slag discharge: cone extraction is mostly large equipment, considering the structure of its seal and bottom heat source. However, it is more difficult to discharge and slag during the production process. Due to the easy clogging of the small area of ​​the bottom material, the liquid discharge is not smooth, and the slag is easy to bridge the bridge, which requires manual assisted slag discharge. The labor intensity of the workers is large, and the occupation time is not large.

4. Operation safety: It is difficult to control the secondary steam flow after the jacket is heated and boiled. Due to the instability of the system steam pressure, the operator needs to adjust the valve to control the steam pressure at any time to maintain the micro-boiling state and control. Heating relative to the heating area is large) It is easy to cause the secondary steam flow to carry the saponin and the floating medicinal material to block the pipeline forming equipment to produce pressure bump. Bring damage to production personnel and bring losses to production.

5. Installation space: This structure has a large diameter and a large bottom, and the occupied space is relatively small.

Advantages of extracting the tank extraction solvent when using water as a solvent:

a. Cheap, easy to use, safe to use.

b. A polar solvent that has strong penetrating power to Chinese medicine cells.

c. The active ingredients in most herbs can be extracted.

Chinese medicine multi-function extraction tank has to say the advantages:

The multi-functional extraction tank is recirculated and extracted, and the amount of feed is large. The dose can be doubled compared to the usual rule extraction. The multi-functional extraction tank has good process adaptability. Water extraction and alcohol extraction can be carried out by atmospheric pressure, negative pressure and positive pressure processes, especially low temperature extraction, concentration and high rate of heat-sensitive materials. Due to the dynamic extraction of the drug, the high solubility gradient between the drug and the solvent increases the leaching driving force and increases the paste yield. More than 5-20% more than the conventional method. The multi-functional extraction tank of traditional Chinese medicine saves time, and the extraction and concentration are completed in one step, and the multi-functional extraction tank of traditional Chinese medicine adopts the return flow twice as much as the conventional one. The whole process only takes 4-6 hours, and the energy consumption is reduced. Because the Chinese medicine multi-functional extraction tank uses secondary steam as the heat source, the extraction and concentration are carried out simultaneously, and the temperature of the reflux condensate is close to the boiling temperature in the extraction tank; and the polyurethane foam is used as the thermal insulation layer, and the temperature and the vacuum degree. It is randomly controlled, and the multi-function extraction tank can save steam by more than 50%.

Multi-functional extraction tank extraction part of conventional extraction and ultrasonic extraction optional: ultrasonic physical effects, cavitation can promote plant cell tissue breakage or deformation, solute particle vibration, acceleration shock, sound pressure shear and other effects The force is strengthened to make the material form an extreme high temperature and high pressure at a local point. At the same time, the multi-functional extraction tank of the traditional Chinese medicine adopts a concentrating ultrasonic generator and frame stirring, so that the large-volume Chinese medicinal material can fully contact the ultrasonic probe and accelerate the effective in the raw material medicine. The components are uniformly precipitated, and the extraction rate is significantly improved compared with the conventional process. Ultrasonic extraction is a normal temperature extraction, which effectively reduces the loss of heat sensitive components.

Ok, the above is all the content shared today, I hope to help everyone understand this device.
