The extraction tank is a leaching extraction equipment commonly used in pharmaceutical chemicals, and is particularly suitable for leaching extraction of components contained in plant products. The structure has a tank body, and the auger or the slurry propeller of the axial position device in the tank body is connected with the rotating shaft plate outside the tank body, and is characterized by a set of inclined countercurrent leaching extraction single tanks, which are mutually arranged The material port is connected with the feed port to form a connector, each of the single tank body has a feed port at a lower end portion thereof, and a residual liquid discharge port at a lower portion, and a liquid inlet port or an exhaust port at a high-end upper portion of the tank body, and the lower portion has a lower portion Feed port.
The extraction tank is a multi-purpose equipment designed for the Chinese medicine factory, cooking and extraction process. It can be extracted in this process, alcohol recovery and volatile oil separation. In addition to the extraction tank main equipment, this equipment is also equipped with a foam trap, a cooler, a water separator. These devices are made of stainless steel in contact with the drug. The heating interlayer is strictly tested and tested by the Wenzhou Pressure Vessel Inspection Department, and the equipment has a long service life. In the extraction process, the equipment is completed by a condenser, a water-oil separator, etc., and is completely sealed and closed in a recyclable system, and the organic solvent is recovered in the waste residue.
Extraction principle:
(1) If water is extracted: water and traditional Chinese medicine are put into the extraction tank, and the heat source for the interlayer is started. After the boiling in the tank, the heat source is reduced, and the boiling in the tank is maintained. The maintenance time is determined according to the extraction pharmacological process, such as the closed extraction needs to be cooled. The water, after cooling the steam vapor, returns to the extraction tank to maintain circulation and temperature.
(2) For example, alcohol extraction: firstly, the medicine and alcohol should be sealed in the tank, and the heat source steam should be given to the interlayer. When the cooling water is turned on, the heat source is reduced when the tank reaches the required temperature, so that the rising vapor alcohol passes through the condenser and becomes liquid alcohol reflux. In order to improve the efficiency, the pump can be forced to circulate, so that the liquid medicine is pumped out from the lower part of the tank to the upper part of the tank and returned to the tank to release the local channel flow.
(3) Lifting oil: first add the Chinese medicine and water containing volatile oil into the extraction tank, open the circulation valve of the oil separator, adjust the bypass return valve, open the supply of the heat source valve to reach the volatilization temperature, turn on the cooling water for cooling, and after cooling The liquid should be kept at a certain height in the separator to separate it, and another oil-water separator should be used alternately.
(4) Recycling oil: Add alcohol to the tank, open the cooling water to the steam, and then open the recovery valve.
