Description
Technical field
The present invention relates to the technical field preparing cigarette extract, the preparation method of a kind of cigarette Rhizoma Coptidis extract of concrete finger.
Background technology
Molecular distillation is a kind of distillating method operated under a high vacuum, and at this moment the mean free path of vapour molecule is greater than the distance between water surface of evaporation and condensing surface, thus can utilize the difference of each component vaporator rate in feed liquid, is separated liquid mixture.
The vertical circular cylindrical shell of short-distance distiller by external heat, the center condenser at it and the blade applicator rotated between distiller and condenser form.Still-process is: material adds from the top of vaporizer, is distributed on hot face through epitrochanterian liquid distributor by its continuous uniform, and feed liquid is spread to that one deck is very thin, liquid film in turbulence-like by blade applicator immediately, and spirally advances downwards.In the process, from the light molecule that hot face is overflowed, on too short route and built-in condenser of almost arriving without collision, be condensed into liquid, and flow down along condenser tube, discharged by the discharge nozzle being positioned at base of evaporator; Raffinate and weight molecule are collected in the circular passage under heating zone, then by flowing out in the discharge nozzle of side.
The coptis, belongs to Ranunculaceae, Coptis per nnial herb.The main component of the coptis is multiple alkaloid, and wherein content of berberine is the highest.
Coptis bitter, cold.The thoughts of returning home, spleen, stomach, liver, courage and large intestine channel.There is heat-clearing and damp-drying drug, the effects such as fire, anticancer, hypoglycemic, lipopenicillinase are let out in removing toxic substances.Full for damp and hot ruffian, vomiting acid regurgitation, rush down dysentery, jaundice, unconsciousness due to high fever, hyperactivity of heart-fire, dysphoria and insomnia, blood-head tells nosebleed, hot eyes, and toothache, quenches one's thirst, and carbuncle swells furunculosis; Control eczema outward, wet sore, duct is suppurated.It is burning hot that prepared RHIZOMA COPTIDIS with vino is apt to the clear part of the body cavity above the diaphragm housing the heart and lungs.For hot eyes, aphtha.Prepared RHIZOMA COPTIDIS with rhizoma zingiberis recens juice clearing stomach and stomach preventing or arresting vomiting.Tie mutually for fever and chills, damp and hot middle resistance, ruffian is completely vomitted.The cornel coptis is relaxed liver and stomach preventing or arresting vomiting.For liver and stomach not get along well, vomiting acid regurgitation.
The coptis have resisting pathogenic microbes effect, antioxygenation, antitumous effect, anti-inflammatory action, anti-CaM antibody, antiulcer action, hypoglycemic blood fat, improve Digestive tract effect, improve the multiple pharmacological effect such as cardiovascular and cerebrovascular diseases, therefore, Rhizoma Coptidis extract is the very potential Chinese-style cigarette novel fragrance of one.Again due to its bitter, appropriate Rhizoma Coptidis extract add in tobacco can not only play improve mouthfeel, the effect of the Hui Tian that promotes the production of body fluid, and perfume quantity and flue gas concentration can be increased.And the current coptis and goods thereof rarely have report in the application in essence spice for cigarette field.
