Description
Technical field
The present invention relates to a kind of material processing device for tobacco business, particularly relate to a kind of tobacco flowing extraction equipment.
Background technology
Extraction utilizes component in system to have different solubility to carry out the unit operations of separating mixture in a solvent, and extraction has two kinds of modes:
Liquid-liquid extraction, also known as extracting, is utilize component in system to have different solubility to carry out the unit operations of separating mixture in a solvent.That is, be the difference utilizing material solubility or distribution coefficient in the solvent of two kinds immiscible (or slightly solubles), make solute in a kind of solvent, transfer to method another solvent.Be widely used in chemistry, metallurgy, food and etc. industry, be common to petroleum refining industry.In addition by the operation that liquid immiscible for extraction latter two separates, be called separatory.
Leaching, is also named leaching, by the component in separated from solvent solid mixture, as with the carbohydrate in water extraction beet; With the soya-bean oil in alcohol leaching soya bean to improve oil yield; From Chinese medicine, active ingredient is leached to produce liquid extract " oozing drop " or " leaching " with water.
According to the feature of tobacco, extraction can only adopt leaching, the method namely leached.Main Means has: 1. water logging is followed the example of; 2. chemical solvent extraction; 3. supercritical extraction.Extract less in the commercial Application of tobacco business, be mainly used in reconstituted tobacoo production process and extraction nicotine, sugar and tobacco extract.The means adopted mostly are water logging and follow the example of, or first use water extraction, then with ethanol or the extraction of tetrachloromethane equal solvent.Simple chemical solvent extraction and supercritical extraction there is no application in tobacco industry.And the object of extraction is to obtain extract, and the tobacco after non-used extraction.
Application publication number is CN102640985A, name is called that the Chinese invention patent of " burnt treatment process and the device for pipe tobacco or tobacco leaf supercritical extract fall in a kind of Harm reduction techniques " discloses a kind of Harm reduction techniques and falls burnt treatment process, this technique is specific as follows: first pipe tobacco or tobacco leaf are carried out supercritical fluid extraction, utilizes the pipe tobacco after the hot blast process extraction of microwave or 80 DEG C-150 DEG C or tobacco leaf after extraction.When pipe tobacco or tobacco leaf extract in supercritical fluid, be placed in a rotation and the device that fully can contact with supercritical fluid.The rotating speed of described device is 10-100r/min, and rotation extraction time is 2-60min.Concrete, pipe tobacco or tobacco leaf are added in airtight extraction container, extracts in supercritical fluid, regulate extraction container temperature to be 20 DEG C-80 DEG C, regulate extracting pressure to be 10-80Mpa; After extraction terminates, in the process of desolvation, the temperature in extraction container remains on-10 DEG C-60 DEG C, from lower vessel portion extracted liquid solvent, extracts the solvent of gasification from the top of container out; Take out overall from container to pipe tobacco or tobacco leaf afterwards, be placed in microwave or hot blast carries out process desolvation.The mixture of one or more in carbon dioxide, HFC-134a, ammonia, propane, butane, iso-butane, dimethyl ether, ether, sulfur hexafluoride, dicholorodifluoromethane, F-22, ethanol, n-hexane is adopted to be extractant.Employing carbon dioxide is extractant, adopts ethanol or acetone or its aqueous solution to be entrainer simultaneously, makes entrainer and carbon dioxide become fluid-mixing; In 20 DEG C-80 DEG C, 5-60Mpa extracts 2-60min; Extraction terminates in the process of desolvation, and the temperature in extraction container remains on-10 DEG C-60 DEG C.Although this invention consider fully the contacting of solvent and pipe tobacco or tobacco leaf, the flowing of solvent, the recovery of solvent and after extracting pipe tobacco or tobacco leaf utilize, but, the extraction of this invention pipe tobacco and tobacco leaf is carried out in extraction kettle, the rotation of the caged equipment relying on the revolution of installing in extraction kettle to rotate reaches the flowing of extractant, not only increase pipe tobacco or tobacco leaf and make broken and risk that the is fault of equipment own, and extract is easily saturated, effect of extracting is limited.
