TN Series Chinese medicine reflux norma low temperature pressure extracting low

Traditional Chinese medicine hot backset current low temperature draw low temperature concentrate unit comprehensive

backset current, ooze and filter drawing, adverse current and hot backset current extraction and concentrate four kinds of

principles.The main features as follows:

        1. Low temperature densely: The main solvent is water and ethanol in the Chinese extracted, if adopt the low extrating and

low concentrating, the water extracting is control in 50℃-90℃, ethanol extracting is control in 40℃-80℃. Because of the low

extracting, it can avoid the chinese medicinal materials active ingredient, especially the organisms activated not esay to destroy,

at the same time it can avoid producing the inefficacy ingredients in the high temperature, such as dextrin, colloid, tannin etc,

improve the products quality, convenient for isolation and purification.

        2. High drawing rate: Because of the extracting pot at the condition of the vacuum pressure and low temperature, it can

enable the chinese medicinal materials cell to expedite expand, cell membrane broken at once, at cell inside, it stripping the

actived ingredient. And the continuously supplement of the reflus-norma new solvent, which it enable the solvent played at

the medicinal materials surface and penetrate into the medicinal materials interior, improve the medicinal attrition elution-force

and the solubility, the medicinal material and the solvent keep higher gradient of concentration and extend ability, having

accelerated the dissovling out of solvent of active principle of the medicinal materials ,improve the extracting rate and the

harvested ointment rate of the chinese medicinal material.

        3. Save the solvent: Only need to join 8 times of solvents of crude drugs quantity once, untilize new solvent conduct of

hot backset current to hot backset current to supplement, which the backset total is equal to the old extracting need 2-3 times

join solvent total, it save the solvent 50%-60%, also it can increased the collecting volume of medicinal materials.

        4. Save steam, the unit in closed and low temperature operation, all maintained liquid temperature in the tank keep in 50-

90℃, heated steam pressure in atmospheric conditions, can significant reduction of the steam power consumption.

        5.Design innovation: Through the vacuum of the vacuum converter and the height difference of the vacuum height suction

of the key design, it shorten the extracting and contracting time, improve the medicinal harvested ointment rate and some

actived ingredient keeping rate.

        6. Advanced craft: Extracting concentrating is go on meanwhile,completion gets medicinal extract directly, shortens the craft.

        7.Computer controled: Adopt the PLC main-machine interface, vacuum converted timing ect, also it can setup the

temperautre controled, vacuum controled, density controled and production original recording printing device.

        8. Lower costs: The all right equipment of aircrew simplifies, washed the convenient, the whole closed operation, has no

environmental pollution, compared with necessary equipment of traditional craft, the equipment reduces by 1/3, the occupation

of land reduces by 2/3, investment can save by 40%, energy consumption can be reduced by 40%, the attendant reduces

by 1/3, so the production cost can be reduced by about 50%.
