Dynamic development of Chinese medicine extract
Traditional Chinese medicine includes experienced dynamic removal dynamic extraction, energetic reflux extraction, strong circulation continuous regurgitate extraction three tips. Dynamic extraction stage Relative to the concentration method for, decoction method, permeability of backflow method, medicine all belong to potent extraction. Decoction method is any medicine yinpian or deep powder for the decoction, not to mention add water to earn submerged medicinal plant based treatments, soaking appropriate Ninety-six second article of China herbal medicine constitution between extraction, orthopedic to a boiling, although the boiling to specific time state extraction method. Medicine yinpian not to mention thick powder the surface of effective ingredients from concentration on the cooking water is lousy mixing effect and implementation, general as compared with immersion method to acquire the effect is good. If perhaps on the mezzanine pot, preventative measure of extractor removal equipment such as putting a mixer, sends, etc, which can notice forced circulation, enhance extraction efficiency. However because the decoction method made use of more water for solvent, high temperature, applies only to effective portion soluble in standard water, and a hot, wet herbs of the a great deal more stable. Permeability method also belong to energetic extraction capsules, medicinal powder in dense is seeping inside of the capsules, pharmaceutical recycleables solvent continuously within the permeability of the superior join filter, petrol seeping constantly belonging to the lower flow released, thus leaching with medicinal materials for effective ingredients about method. According to the various method of operation, and often will permeability of leaks in the structure of single tubes capsules, heavy permeability and pressure supplements permeability of tubes, counter-current permeability of capsules method, etc. A single capsules used a great deal more solvent method permeability; Heavy permeability associated with a solvent a supplements can DuoCi use, this solvent consumption is undoubtedly single permeability technique to reduce capsules, together with permeability in the very smooth of effective ingredient capsules of higher concentration, don't have to warming up enrichment, can avoid the successful component thermal decomposition or volatile deprivation, product quality is, but accounts for bigger container, the operation of a tough time, more time consuming; Seepage demand capsules can make the solvent and using solution quickly via the powder column, make the permeability source well, improve the leaching result, extract concentration, synthetic cleaning agent consumption is compact; Glutathione Counter-current permeability source way is medicinal materials and also solvent in leaching tank in the other along the movement, the actual continuous and fully contact with the method about extraction, belong to active reflux extraction. Backflow technique is with ethanol, and other volatile organic solvent extraction medicinal materials successful components, will using solution heating distillation, such as volatile dissolvent again after gasification by condensation, circulate back to the using sedimentate polysaccharose, medicinal herbs, example round and rounded, until the effective aspects of the method of completely. Resveratrol Reflux technique can be divided into backflow sizzling hot leaching and backflow quenching strategy. Reflux method is as good as the permeability associated with capsules solvent content is small, typically the solvent can reuse, but hot leaching solvent can only backflow recycling where possible, can not keep newer and the backflow quenching method can recycle solvent, and will be updated, the actual solvent consumption, put is completely carry. Thanks to continuous reflux procedure heating, dip lug liquid leaching during the heating time can be longer, so does not apply to heat on the damage of medicinal items to leaching. Dynamic reflux extraction measure Spiral reflux removal device spiral regurgitation extraction using compelling principle, the diffusion about medicinal materials particles interface effective product drug around rather quickly to solvent diffusion, diffusion slot always maintain higher levels inside and outside is bad, and to realize the key of application acid reflux extraction work phase medicinal materials particles inside and outside maintain a standard interface spread the particular concentration of the poor. Flow back extraction device, group by hopper, feeding conveyor just for spiral, rotary extraction roller, slag discharge spin out of control conveyor for composition. The content coarse crushing, over time after extraction from your shots in the hopper, through feeding conveyor for control compulsory pushed right rotary extraction on the drum, slow roller revolving, fixed in the curler on the wall considering the spiral materials out of your front to back slow advancement, and extraction favourable from the end in the unit into dissolved pipe into the extraction in the cylinder, your roller back-end through the materials move forward end movement, solid-liquid two-phase material in this contrary movement full call, and the effective portions of medicinal materials eliminated. The liquid dregs spin conveyor for mandatory move to the mouth and slag discharge units, Chia plant seeds and the dregs of fruit juice to spiral as well as for extrusion, will the residual substance solution extrusion medicinal product organization, reduce the residual liquid solution content and articles. 97 Chinese plant based medicine composition extraction and separation and then preparation processing completely new technology and unique process, new ordinary practical handbook Ninety-eight Chinese herbal treatments composition of the instant article extraction know-how spiral pole form continuous reflux extraction equipment is dynamic extraction, reflux extraction, decoction removal technology, combined with the customary process in book DuoZhong advantages at the same time, create the traditional process is able to do many advantages: extraction accelerate is quick, valuable components from fully, extraction yield high; Favourable consumption, high power of liquids, reduce water loss and concentration pertaining to treatment working method; Roller herbs with movement speed versatile particles, which can modify according to the characteristics connected with herbs extraction period length; Medicinal resources in mild forceful environment is taken out, and heating temperatures are lower, effective section little damage, cause solution impurity content during the less; Belong to following production, processing ability. Dynamic warm captivation extraction equipment compelling warm immersion removal equipment is using appliance forced circulation system, Docetaxel the solvent removal in the interior on the top-down continuous loop, today's leaching, make sound, liquid two-phase produce larger relative velocity, also, the diffusion boundary layer get more thin, speed up any solute in medicinal resources to the spread about solvent. Dynamic heat immersion process run chart. Figure dynamic warm immersion procedure:-dynamic warm immersion ales, -clip casing heater; -pump; -solvent storage space tanks; -the condense esophagus; -cooler; -among solvent dynamic warmer immersion technology port, has the following traits: leaching temperature is low decoction method, which can protect against medicinal materials, colloid substance in starch gelatinization, intense inflation, influence that solute, can avoid once again because of its tremendous draining and cause divorce and enrichment difficulties; Therapeutic material surface area, improve the entire speed of the solute dissolution, multiply; Leaching time brief, solid, liquid a pair of phase of the general velocity increasing, additionally, the diffusion interface layer new quickly, solute diffusion balance hours short; Less solute decline. Chinese herbal remedy composition extraction in addition to separation and planning processing new systems and new approach, new standard realistic manual MiaoQing methamphetamine content in as the assessment index, compared all of the decoction method and strong warm immersion extraction extraction effect: some sort of using decoction method, twice the of water, decoction times, anytime, three times with extract, measured in meth for); Another apply dynamic warm engagement technology, double the amount of water, dip mention climate, extraction twice, 1st, for the second moment, merger extract, appraise the content of meth for). Fructus schisandrae ethanol solvent very same dosage, Irinotecan reflow law to help extract two times, everytime 0, fructus schisandrae b part content measured intended for); Dynamic warm captivation [(1)] removal two times, each time, along with the method of fructus schisandrae, of content is 11 b). Given that forsythia ester unstable nucleoside properties in acid, encounter warmth can decompose and also RenYanJiu on the dynamic extraction research; In favourable extraction temperature, usage, extracting time for the reason that examine factors, Takes advantage of the two orthogonal table check, the best dynamic had been extraction technology problems for 0 conditions the volume of water, One continuous dynamic removal 0. Compared with the traditional decoction method, dynamic extraction (thick powder) technique are presented for) any nucleoside ester content 3), and even Fried cooking opportinity for) 3). Visible dynamic warm immersion removal has spread quickly, mass transfer practice temperature advantages, could avoid the leaching time is too long and lead to destruction for effective ingredients from decomposition. Dynamic continual reflux extraction state cycle step Active cycle stages in 2 th century against extraction s began to implement. The first is the removal of circulating forceful tank, its attribute is exterior warming, and the cycle alternative dynamic extraction, slag give off mouth have able, filter board, can own filtering, has a lot of function, can a particular tank extraction, ales group downstream, counter-current extraction. Two-way external heating the cycle of potent extractor in years begun to use, Plant extracts in addition to the cone design and dynamic traits extractor as circulation outside, still have the below features: the principal a cylindrical dive bombs in type heater, outside the sandwich partition, the next two section, cellular welding, circulating pump out flow, head for the low. Dynamic flow continuous reflux extraction phase is for chinese people medicine routine utilization of solvent extraction device is insufficient, will DuoGe removal unit scientific solution, between units focus gradient (material and also solvent) reasonable plan and the corresponding progression configuration. Each equipment use forced flow by mechanical will mean method, the synthetic cleaning agent top-down or bottom-up continuous action, the current leaching, earn solid, liquid two-phase produce higher relative swiftness, improve the solid Check out liquid interface stratum diffusion of updated pace, improve leaching efficacy.
