High Performance Stainless Steel Chinese Herb Extraction Machine

Accessories

The tank is equipped with CIP cleaning automatic rotating spray ball, temperature gauge, pressure gauge, explosion-proof sightglass lamp, sight glass, quickopening feeding port, etc., to ensure easy operation and meet GMP standards. The inner cylinder of the equipment is made of 304 and 316L.

Working principle of extracting

1.water extraction: water and Chinese traditional medicine according to certain proportion to inner tank, open the jacket steam stop valve and start to heating extraction. In the extraction process, can produce a large amount of steam, the secondary steam goes through foam catcher to cooler for condensation, then into the cooler for cooling, and then into the oil-water separator for separation, condensate liquid goes back into the extracting tank so until the extract is terminated. when extracting liquid reaches the requirements of the extraction process, stop heating.
2.Alcohol extraction: drugs and alcohol be put into the inner tank by certain proportion first, must work at sealing condition,, open the jacketed begin evaporating into the valve for steam heating extraction. In the extraction process, within the tank will produce a large amount of steam, the secondary steam from the steam vent for discharge, through foam catcher to cooler for condensing, again into the cooler for cooling, then enter the gas-liquid separation for separation, making the residual not cold gas escape from upper condenser, liquid reflux to extractor, so until the extract is terminated, when extracting liquid reaches the requirements of the extraction process, stop heating.
3.0il extraction: putting traditional Chinese medicines which contains volatile oil in to extractor first, open the circulating valve of oil separator, close the bypass back flow valve, and open the jacket steam valve, when reaches evaporating temperature, open the cooling water for cooling, the cooling liquid should maintain a certain level of errands separation in the separator.
4.Forced circulation: In the extraction process, to improve extracting efficiency, can make medicine force circulation by pump(But for medicine with more starchy and larger viscous, extraction forced.circulation is not applicable), that is, medicine liquid from the bottom of tank to put liquid pipe out, through the double filter, and then reflux to tank with liquid pump for extraction

Features

1. This multi-function extraction tank is high efficiency, is the latest developed small dynamic extraction tank, saving raw material and working time is 10%~15% higher than the general extraction tank.
2. Raw material conversion rate is high, in the process of extraction hot solvent (water or alcohol etc.) continuously added to the raw material medicine, effective components from the material continuous dissolution from top to bottom, make the effective components in original liquid twice as general extraction tank.
3. The extraction tank use paddle stirring, make large volume herb can fully exposed to solvents, accelerate the precipitation of effective components in the raw materials.
4. This dynamic extractor has large aperture manhole or hand hole, convenient for taking herb dregs, and has filter system, prevent fine dregs to flow to the concentration unit.
5. The extraction tank has compact structure, small occupation area, the actual area about 2 m2, convenient to operate.
6. This extraction tank is not limited by herb components polar and molecular size, suitable for most herb materials. Adopts full closed inner circulation structure, has oil-water separator, condenser and cooler, can extract aromatic oil and vegetable essential oil at high efficiency.
