Application: The device is used to extract the herb, flower, seed, fruit, fish etc. It can be used for food and chemical industries in normal pressure, micro-pressure, water frying, heat cycling, cycling leaking, redolent oil extract and organically solvent recycle. There are four kinds of the extracting tanks series: the mushroom type extracting tank, the Upside-down taper type extracting tank, the straight cylinder type extracting tank and the normal taper type 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 Equipment characteristics: The equipment be applied to the multiple technology operation of normal pressure, micro pressure, water frying, warm soaking, thermal reflux, compulsory circulation, filtration, food and chemical industry. The prominent characteristics of the large and small taper type extracting tank is that the slagging is very convenient with good heating effect. The tank body is equipped with CIP cleaning automatic rotary spraying ball head, temperature measuring hole, explosion- proof view lamp, view mirror, rapid open feeding inlet etc., which can guarantee the convenient operation and is in accordance with GMP standard. The tank body inside the equipment is made of imported SUS304, and the jacket is made of completely sealed aluminium silicate blanket for temperature holding. The external tank body is stuck with SUS304 semi-luster thin steel sheet for surface decoration. The complete equipment supplied shall include: Demister, condenser, cooler, oil and water separator, filter and control desk for cylinder etc. Slag door classification: Rotary type residue discharging door The tank cover can be automatically opened and closed. High temperature and high pressure extraction can be realize, and more than 3Bar can be achieved in the swivel type product. It provides more selection for extracting technology. It can also meet some special technological requirements. With good safety and reliability, it has sufficient safety guarantee functions and the has no leakage. Rapid open safety discharging door The tank cover can be automatically opened and closed. It adopts cylinder control and is provided with safety device to avoid accidental operation and provide high safety factor. It is suitable for use in small and medium-sized reside discharging vent. Large-diameter residue discharging door The tank cover can be automatically opened and closed. High temperature and high pressure extraction can be realized to provide more selection for extracting technology. With high safety factor, the residue discharging door is suitable for residue: discharging of large-diameter upside-down taper type extracting tank. Accessories: The tank body is equipped with the CIP automatic rotary spray cleaning ball, thermometer, pressure gauge, explosion-proof aperture lamp, sight glass, quick open type feeding inlet and etc., ensuring convenient operation and complying with the GMP standard. The cylinder inside the equipment is made of imported 304 or 316L.
