Description
Technical field
The utility model belongs to technical field of chemical, and in particular to a kind of compact-sized, ethyl alcohol organic efficiency and returns
High income, energy-saving and environment-friendly industrial hemp extraction CBD alcohol solvent retracting devices.
Background technology
Hemp（Cannabis satival L.）For the annual male and female of Dicotyledoneae Urticales Cannabaceae Cannabis
The herbaceous plant of different strain is commonly called as hemp, Chinese fiber crops and fire fiber crops.Hemp is due to containing tetrahydrocannabinol（THC）It can make one to cause unreal habituation,
It forbids cultivating within suitable long-term hemp.Industrial hemp refers to the hemp that tetrahydrocannabinol content is less than 0.3%, it is considered that does not have
Standby extraction drugs are worth and are sucked directly as drugs, are a kind of industrial crops for being approved legal plantation.Industrial hemp is generally adopted
It is abandoned by the use of its footpath skin as fibrilia raw material, floral leaf etc. essentially as waste material, not only pollutes environment, but also also reduced industrial big
The economic value of fiber crops.Cannabidiol（Abbreviation CBD）Female hemp plant is extracted from, is the non-additive ingredient in hemp, has
The pharmacological actions such as anti-spasm, antianxiety, anti-inflammatory, the additive ingredient THC that can also effectively eliminate in hemp generate human body
Hallucinogenic action.Therefore, cannabidiol be widely used in pharmaceuticals industry, food service industry, healthy industry, beauty industry and
Other industries.
At present, the technique of cannabidiol is extracted from industrial hemp floral leaf both at home and abroad mainly there are two direction：One kind is to adopt
With co_2 supercritical fluid extraction technology（Such as United States Patent (USP) US20040049059）, second is using traditional solvent
Extractive technique（Such as Chinese patent CN201410052776）, two ways can effectively extract the hemp two in hemp floral leaf
Phenol.At present, it is solvent extraction techniques using more method in terms of plant component extraction, compared with other methods, dashes forward
The advantages of going out is that consumption of organic solvent is few, quick, the rate of recovery is high, which has been chosen to be the standard method of recommendation by the U.S..Although
Solvent extraction is the new technology of just development in nearly 2 years, but the advantages of protruded due to it, has received the very big concern of analytical chemistry circle.
Ethyl alcohol be the molten coal of semi-polarity, solubility property between polarity and it is nonpolar between, can dissolve water-soluble some
Ingredient, and some ingredients that nonpolar solvent is dissolved can be dissolved, and with ethyl alcohol extraction can Chinese medicine can reduce in medicinal material and glue
The leaching of the impurity such as liquid matter, starch, protein.In addition, when making solvent with ethyl alcohol, because ethyl alcohol expands small, Chinese medicine to medicinal material
Can powder improve extraction effect into coarse powder.Therefore, ethyl alcohol effect solvent is widely used in the row such as pharmacy, food, light industry, chemical industry
Industry.Pollution for the use cost for reducing ethyl alcohol solvent and to environment, alcohol recovering device are able to extensive use.Ethyl alcohol recycles
Tower is the setting being most widely used at present, it is the principle for being less than other solution boiling points using alcohol boiling point, with a little higher than wine
The dilute alcoholic solution that need to be recycled is carried out heating volatilization by the temperature of smart boiling point, after tower body essence gold-plating, absolute alcohol gas is precipitated, carries
The concentration of high alcoholic solution, achievees the purpose that recovered alcohol.But there are organic efficiency is low, second for existing alcohol recovering device
The alcohol rate of recovery is low, energy consumption is larger, ethyl alcohol it is volatile pollution environment the problem of, industrial hemp extract CBD during how efficiently,
Energy-saving and environment-friendly recycling alcohol solvent is related to the cost of CBD extractions and the problem of environment friendly.
Utility model content
