pharmaceutical mahcine characteristic: FEATURES: 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. abstraction, concentrate two processes go on at the same time, one finish traditional medicine draw, concentrate the new craft of traditional Chinese medicine, take to change the draw potkeep high temperature with atmosphere fry the craft of boiling, utilize vacuum toshoulder proceed low temperature draw and low temperature concentrate, makeworking temperature to draw pot control in 60-80,concentrate temperature control in 50-70, guaranteee crude drugs effective composition the distillation loss. Meanwhile draw and concentrate produced two steam enter backset current condenserbecome hot condensation liquid, falling back to and drawing it the pots, add to the crude drugs as the new solvent, the new solvent is passed the crude drugs layer from top to bottom, having played a oozing and filtering dynamically role, the soluble material which dissolves the crude drugs reaches the draw pot bottom, enter the concentrating device to concentrate again. According to practical experience and study for many years, hot condensation liquid of backset current invite within 2.5-3 hours drawing former solvent of pot all change once, can keep a higher density to the draw pot crude drugs in unit time. MAIN CHARACTERISTIC: t unstability is easy to be destroyed when heated in the crude drugs, and propose the dense craft in low temperature, those abstraction of wet, heat, only sensitive material and fragrant hydrocarbon and material is very suitable, and the Chinese herbal medicine composition is comparativel complicated; majority have temperature sensing nature, can is it is it keep atmospheric pressure high temperature draw whom course might emerge resolve to take to avoid in this war, form and compound things to precipitate etc. And react, can keep the original characteristic of the crude drugs and drug effect to the greatest extent. (2) Advanced craft: traditional Chinese medicine is it get draw liquid to draw, draw liquid is it get two process of medicinal extract is it draw to turn into to concentrate and then-cocentrate process to be centralized to go on meanwhile, completion gets medicinal extract directly, shortens the craft. (3)Save the solvent: Only need to join 5-6 times of solvents of crude drugs quantity once, utilize new solvent conduct of hot backset current to hot backset current to supplement, can make the input amount of the crude drugs ncrease at double. (4)High drawing rate:Because the constant supplement of solvent of the hot backset current, make crude drugs and sllvent remain higher density throughout, having accelerated the dissolving out of active principle of crude drugs, it is comparatively complete to draw. (5)Lower costs:The all right equipment of aircrew simplifies, washes the convenient, the whole closed operation, has no environmentalpollution, compared with necessary equipment of traditional craft, the equipment reduces by 2/3, the occupation of land reduces by 2/3, investment can save half, energy consumption can be reduced by 30%, the attendant reduces by 2/3, so the production cost can be reduced by about 50%. technical parameter Item\ Model
