Extraction and concentration using dynamic extraction and ultrasonic extraction, short time, high efficiency; The equipment adopts electric heating mode, high degree of automation, tank equipped with CIP cleaning head, in line with GMP medical standards, the equipment is mainly suitable for universities, research institutes and enterprises and institutions laboratory ** * and small test production lines. It is suitable for atmospheric pressure, micro-pressure, water decocting, warm immersion, thermal reflux, osmosis, extraction of aromatic oil and recovery of organic solvent in traditional Chinese medicine, plant, animal, food, beverage, chemical industry and other industries.
How extraction and concentration work:
Put the medicinal materials to be extracted into the extraction tank, and add the plant aromatic oil refining equipment into a certain proportion of solvent according to the production process (add according to the process). For active drug extraction, extraction temperature can be set according to actual needs. Extraction is carried out according to the production process. After extraction, the pipeline valve is opened in sequence and the liquid is pumped into the concentration tank for concentration.
Concentrate temperature setting value, there is a need for vacuum degree in a certain range, concentration when the secondary steam through the condenser and cooler into condensate return to extract can make a new solvent in medicine, a new solvent top-down by medicinal material layer to the bottom of the extracting tank, soluble constituents of medicinal materials dissolved in the solvent extraction tank, to do a new solvent extraction tank, forming new solvent reflux extraction, Concentration continues until it is completely dissolved (the extract is colorless) until it is concentrated into the required specific gravity ointment. The colorless liquid in the extraction tank can be reused next time.
Installation instructions for extraction and concentration:
1. After the equipment falls, it is fixed on the platform by bolts or spot welding, and the four supports are required to carry out uniform force.
2. The process pipe relies on the liquid gravity flow section, and a certain level difference should be left in order to avoid liquid retention in the pipe.
3. The external pipe at the joint of the quick-change rotary pipe should be supported so that the rotary joint can rotate with the slag discharge door cover to prevent damage to the liquid outlet hose of the slag discharge door.
4. Liquid flow meter should be installed at the mouth of liquid inlet pipe to facilitate the recording of liquid inlet.
5, steam pipe must be installed pressure reducing valve, valve, pressure gauge and other accessories.
