Stainless steel dynamic extraction tank

The extraction tank is a multi-purpose equipment designed for traditional Chinese medicine factories to extract, recover alcohol, and separate volatile oils during the boiling and extraction processes. In addition to the main equipment of the extraction tank, this device is also equipped with a foam catcher, cooler, oil-water separator, etc. These devices are made of stainless steel at all contact points with drugs, and the heating interlayer has been strictly inspected by the pressure vessel inspection department. During the extraction process, this device is composed of a condenser, oil-water separator, and other components, and is completed in a fully sealed and recyclable system. At the same time, organic solvents are recovered from the waste residue.

Type of extraction tank:

Stainless steel dynamic extraction tankExtraction principle:

(1) Such as water extraction: Water and traditional Chinese medicine are loaded into the extraction tank, and the interlayer heat source is started. After the tank boils, the supply of heat source is reduced, and the boiling inside the tank is maintained. The maintenance time depends on the extraction pharmacological process. If closed extraction is required, cooling water is given to cool the steam vapor and return it to the extraction tank, maintaining circulation and temperature.

(2) Like alcohol extraction: First, add the medicine and alcohol into the tank, which must be sealed. Steam the interlayer heat source, turn on the cooling water to reach the required temperature in the tank, and reduce the supply of heat source. Then, let the rising vapor state alcohol pass through the condenser and become liquid alcohol for reflux. In order to improve efficiency, a pump can be used to force circulation, so that the medicine is sucked out from the lower part of the tank through the pump and then imported back into the tank from the upper part of the cylinder, relieving local channeling.

(3) Oil extraction: First, add the traditional Chinese medicine containing volatile oil and water into the extraction tank. Open the circulation valve of the oil separator, adjust the bypass reflux valve, and open the supply heat source valve. When the volatilization temperature is reached, turn on the cooling water for cooling. The cooled liquid should be kept at a certain height in the separator to separate it, and then use the oil-water separator alternately.

(4) Recycling oil essence: Add alcohol to the cylinder, open the cooling water for steam, and then open the recycling valve.
