适用范围Scope of application：
It is mainly used for the extraction of materials by using water and organic solvents in the pharmaceutical, food and chemical industries, and can realize a variety of process operations such as atmospheric pressure and pressurized extraction, warm soaking, percolation and heat reflux.
Extraction tank, mist eliminator, condenser, cooler, oil-water separator, duplex filter, pump, feeding system and control system.
Straight cylindrical type, basket type, positive cone type, inverted cone type and mushroom type
The structure of the slag-discharging door adopts tooth-locked self-locking revolving door of the fourth generation to meet the safety requirements of pressurized extraction.
The slag-discharging door gasket adopts the self-pressurized linear gasket. The higher the pressure in the tank, the more reliable the gasket is and the longer the service life is.
Mirror polishing of the inner wall of the tank, rounded transition of the weld seam, no hanging material, easy to clean.
Oil-water separator (patented product) has good oil-water separation effect. It is convenient for oil collection, and can automatically collect various essential oils;
The liquid outlet pipe is a hard pipe instead of the traditional hose, which features no leakage, long service life, safety and reliability.
The bottom cover is provided with a bottom heating device, which can control the temperature of each area in the tank at about 1℃;
Basket type extraction tank: A variety of medicinal materials are put into a plurality of hanging baskets and slag is discharged from the top of the tank, which solves the problems of long decoction time and low yield caused by thick accumulation layer and less circulation of traditional extracted medicinal materials. Its special structure and unique material circulation mode are more conducive to the extraction of essential oil, effectively shortens the extraction time, and improves the clarity of liquid medicine and the yield of effective components.
