Abstract
The invention relates to a production method for extracting tobacco leaf clean oil. The production method includes: taking tobacco leaves and/or waste defective tobacco powder as raw materials; disposing the raw materials in an extracting device of an ultrasonic generator after drying and smashing; using fat-soluble organic solvent for extraction, using water-soluble organic solvent for dissolving, and obtaining needed tobacco leaf clean oil through filtering and depressurizing and compressing of filtrate. A principle that ultrasonic waves are high in penetrability in liquid medium is utilized, so that the solvent can quickly immerse the tobacco leaves and break cells at normal temperature and within short time to enable tobacco oil to be extracted by the solvent as soon as possible. Extraction is completed at the normal temperature and within the short time, solvent consumption is low, and oil yield is high, so that energy consumption is lowered remarkably, yield is increased, production cost is lowered greatly, and operating dangerousness is lowered relatively.
Description
Technical field
The present invention relates to a kind of production method extracting absolute oil of tobacco leaves, belong to chemical industry preparing technical field.
Background technology
Absolute oil of tobacco leaves is had many uses in daily life, and in tobacco business, absolute oil of tobacco leaves is a kind of adding ingredient often used, or is used as the indispensable allotment composition of smoking cessation product.In addition, the fragrance special due to it and certain physiological activity, many chemical products often it can be used as the additive extensive use of a kind of blending or antibacterial desinsection etc.In recent years along with cigarette substitute electronic cigarette constantly by increasing smoking fan is accepted, also requisite absolute oil of tobacco leaves is had as in the atomized liquid of electronic cigarette, along with the consumption in electronic cigarette is increasing, also there is the uneven absolute oil of tobacco leaves of quality simultaneously, even there is the product filling absolute oil with tobacco leaf extract, cause the quality of the atomized liquid of electronic cigarette and taste often unstable.
In the extracting method of known absolute oil of tobacco leaves, conventional is solvent extraction: namely by tobacco leaf amount 20-40 doubly (v/w) organic solvent heating and refluxing extraction more than 3 times, within each return time 1-6 hour, (return time is long for the first time, reduce return time gradually later each time, total extraction time is about 6-8 hour), collect extract, the processes such as warp is concentrated obtain absolute oil.Solvent extraction operation is relatively simple, and the producer easily grasps, but uses a large amount of volatile organic solvent in producing, and solvent loss is large, and operational danger is higher; Extraction time is long, and production efficiency is low; Comprehensive production cost is high.Report is also had to adopt supercritical extraction and microwave―assisted extraction.A kind of supercritical extraction is disclosed in patent document 02133758.6, main is solvent with liquid carbon dioxide, the absolute oil quality better extracted, oil yield is high, but complicated operation, the producer is difficult to generally grasp, production cost is very high, and for extracting on a small quantity, very high-grade absolute oil class is proper, if for the production of absolute oil of tobacco leaves, one is that production capacity is too low, but cost is too high.In addition, disclosed in patent document 200810186049.5, laboratory microwave assisted Extraction follows the example of the method for absolute oil of tobacco leaves, although it is large to overcome Conventional solvents extraction method solvent loss, and the shortcoming that operational danger is higher, also overcome overcritical extraction extraction method complicated operation simultaneously, production cost is lower than supercritical extract, but it is also the research method in laboratory, does not still realize producing, and extract with mixed organic solvents, solvent is difficult to recycling, and waste is large, and cost is naturally high.
Moreover for the absolute oil of tobacco leaves that prior art is openly extracted, the applicant thinks, should be it and add corresponding health-care efficacy, be worth to improve absolute oil of tobacco leaves itself.
Summary of the invention
The object of this invention is to provide a kind of production method extracting absolute oil of tobacco leaves, using tobacco leaf and/or waster tobacco as raw material, insert in the extraction element of band supersonic generator after drying and crushing, dissolve with water-miscible organic solvent again with fat-soluble Solvent Extract methods, after filtration, filtrate reduced in volume obtains required absolute oil of tobacco leaves.
The present invention completes according to the following steps:
1. using tobacco leaf and/or waster tobacco as raw material, being dried to moisture is 10-12wt%, is ground into the offal that particle diameter is less than 5mm;
2. insert in the extraction element of band supersonic generator, 0.5-2 hour is soaked with the 4-20 of material quantity (kg) fat-soluble organic solvent (liter) doubly, then open supersonic generator to extract 1-2 time at normal temperatures, each 10-30 minute, collect extract, with Vacuum Concentration actuator temperature at 30-60 DEG C, obtaining proportion after decompression and solvent recovery under the condition of vacuum .05-0.08mpa is the tobacco leaf extract of 1.1-1.4;
3. tobacco leaf extract dissolves with the 1-20 of medicinal extract weight (kg) water-miscible organic solvent (liter) doubly, place 2-12 hour, filter, filter residue stays and uses it for anything else, the Co-Q10 of filtrate weight (with a kilogram metering) 3-5% is added in filtrate, at temperature 30-60 DEG C, vacuum is under .05-0.08mpa condition, obtains required absolute oil of tobacco leaves after reduced pressure concentration recycling design, or after dissolving with the 1-20 of medicinal extract amount water-miscible organic solvent doubly, freezing 2-20 hour at 0 to-40 DEG C, filter, filter residue stays and uses it for anything else, the Co-Q10 of filtrate weight (with a kilogram metering) 3-5% is added in filtrate, at temperature 30-60 DEG C, the higher absolute oil of tobacco leaves of quality is obtained after reduced pressure concentration recycling design under vacuum 0.05-0.08mpa condition, period, Co-Q10 is at said temperature, under vacuum degree condition, can merge with absolute oil of tobacco leaves to greatest extent, both fusion rate promote greatly, prevent in the crystallization phenomenon of Co-Q10 in storing process in the future.
Described drying, refers to that nature dries or 80-85 DEG C of oven dry;
Described supersonic generator, frequency is 20-40KHz, power 1-20KW.
Described fat-soluble organic solvent is the one in benzinum, n-hexane, solvent naphtha, benzene, chloroform, ether and ethyl acetate;
Described water-miscible organic solvent is the one in acetone, ethanol and methyl alcohol;
The invention has the advantages that: the principle that the penetration power utilizing ultrasonic wave in liquid medium is strong, at normal temperature, solvent in the short time, can be made to infiltrate tobacco leaf fast and oil vacuole is broken, thus make tobacco tar as early as possible and as much as possible by extraction.Complete extraction due at normal temperatures, in the short time, and solvent load is few, oil yield is high again, and significantly reduce energy consumption, improve output, production cost reduces greatly, and simple to operate being easy to is grasped, and relatively reduces the danger of operation simultaneously.
Simultaneously, Co-Q10 is added at the eve prepared by finished product absolute oil of tobacco leaves, the effect of the Co-Q10 that the finished product absolute oil of tobacco leaves of gained is had simultaneously, period, Co-Q10 has another name called Ubidecarenone, it is a kind of fat-soluble quinone, its similar is in vitamin K, because of the side chain on its parent nucleus six---the degree of polymerization of polyisoamylene base is 10 and gains the name, it is a kind of quinone cyclics, Co-Q10 can make nutriment be converted in human body mitochondria in the process of energy to play an important role, also obvious lipoid peroxidization resistant, tobacco tar and coenzyme combine by the present invention, it makes tobacco tar form and is provided with health-care efficacy, realize effect of health medicine, become health care tobacco tar.
