Freeze-dryer equipment for freeze-drying applications of extracts from industrial hemp flowers and leaves!
Industrial cannabis refers to cannabis with a content of less than 0.3% of tetrahydroda-mastol. China refers to industrial cannabis as hemp. It is a one-year herb of the cannabis family. For industrial hemp. The powder made from the stalk core of industrial hemp, which is the hemp stalk core ultrafine powder modified coating technology, is applied in military uniforms, which can exert the high strength and high performance characteristics of the product.
 Freeze-drying machine freeze-drying application process for extracting industrial hemp flowers and leaves:
1) Crush the flowers and leaves of industrial hemp for experiment, and pass through a 10-mesh sieve to obtain the medicinal powder. It was dried at 200 ° C for 0.5h, and the moisture content was 2.7%.
2) The above medicinal powder is extracted twice with 100 v% ethanol and ultrasonically once for 1 h each time to obtain an extraction solution;
3) When the above extract is concentrated, when concentrated to 50 ° C, the relative density is 1.35 to obtain an extract;
4) 10 times purified water was used for the above extract, and water was allowed to sink for 48 h at a temperature of 0 ° C to obtain a water sink solution;
5) centrifuging the above-mentioned water-settling liquid at a rotation speed of 10,000 rpm, and adding 10v% ethanol to the precipitate obtained by centrifugation to dissolve to obtain an alcohol solution of the precipitate;
6) Column chromatography is performed on the alcohol solution of the precipitate. The packing of the column is MCI resin, and the desolvent is ethanol and water. The elution step includes elution with 10 v% ethanol to remove impurities, and then Elute with 40v% ethanol to obtain the target product fraction, and then elute with 90v% ethanol to regenerate the chromatography column;
7) The eluate obtained in step 6) is concentrated to a relative density of 1.25 at 50 ° C and dissolved at 60 ° C in ethanol at a temperature of 80 ° C to obtain a crystal;
8) The crystallized product of step 7) is then washed at a temperature of 24 ° C by adding 5v% ethanol to obtain a preliminary product;
9) Mix the initial product described in step 8) with purified water, put it in a lyophilizer and perform vacuum freeze-drying to obtain cannabidiol.
10) The cannabidiol obtained in step 9) is lyophilized and pulverized to obtain the product.
 In China, Yunnan, Heilongjiang, Jilin and other provinces have issued industrial hemp industrial policies. Take Yunnan as an example: (1) On January 1, 2010, Yunnan Province implemented the “Provisions on Industrial Cannabis Cultivation and Processing in Yunnan Province”, which has become the first province in China to allow and supervise the cultivation of industrial cannabis. (2) In 2012, the Yunnan Provincial Government has listed industrial cannabis as one of the development priorities of the “biomanufacturing industry” and proposed to invest in the construction of a high-tech industrialization processing base for industrial cannabis medicine, food, health products, and daily chemical products in Yunnan. Strategic deployment. (3) According to the data provided by the Narcotics Control Bureau of the Public Security Department of Yunnan Province, from 2010 to 2014, Yunnan approved a total of more than 220,000 acres of industrial cannabis, covering Kunming, Yuxi, Honghe, Wenshan, Chuxiong, Lijiang, Baoshan, Qujing, and Xishuangbanna. Wait for 38 counties (cities, districts) in 13 states (cities).
