Embodiment 1

[0025] Embodiment 1: A process for extracting dihydrocannabinol (CBD) from industrial hemp, characterized in that the process is achieved through the following steps:

[0026] In the first step, the raw materials are flowers and leaves in the full flowering stage. At this time, the content of CBD is relatively high. The flowers and leaves are pre-dried or baked, the water content is between 10% and 15%, and the dust content is below 3%. Put the raw materials into the baking equipment, control the temperature between 130-160°C, and control the time for 15-35 minutes. The purpose of drying is to bake the moisture in the flowers and leaves to between 3 and 5%, and the other purpose is to promote the post-ripening period of CBD. This process can increase the amount of CBD extracted, and the heat source can be heat transfer oil, electricity, steam, etc.

[0027] The second step is to grind the dried flowers and leaves to 5-10 meshes, which can expand the contact surface area betwe...

Embodiment 2

[0038] Embodiment 2: A process for extracting dihydrocannabinol (CBD) from industrial hemp, which is extracted by continuous soaking, characterized in that the process is realized through the following steps:

[0039] In the first step, the raw materials are flowers and leaves in the full flowering stage. At this time, the content of CBD is relatively high. The flowers and leaves are pre-dried or baked, the water content is between 10% and 15%, and the dust content is below 3%. Put the raw materials into the baking equipment, control the temperature between 130-160°C, and control the time for 15-35 minutes. The purpose of drying is to bake the moisture in the flowers and leaves to between 3 and 5%. Another purpose is to promote the post-ripening period of CBD. This process can increase the extraction amount of CBD. The heat source can be heat transfer oil, electricity, steam Wait.

[0040]The second step is to grind the dried flowers and leaves and store them in the storage b...

Abstract

The invention discloses a technology of extracting dihydrogen cannabinol from industrial cannabis sativa, and belongs to the technical field of biology. The technology comprises procedures of picking flowers and leaves, drying, crushing, soaking, extracting, concentrating and separating. The technology can implement complete recycle of media, and zero release and zero pollution for raw material classified extraction and waste comprehensive utilization. The technical processes from concrete extraction to separation of various substances as well as CBD purification all adopt international advanced technologies and meet international advanced standards.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a technology for extracting dihydrocannabinol (CBD) from industrial hemp. Background technique [0002] Cannabis cultivation has a long history. In ancient times, hemp was mainly used to make and process ropes, fishing nets, clothing and paper-making raw materials, as well as oil and food. With the development and progress of society, people have discovered that a toxic ingredient (tetrahydrocannabinol) in marijuana can make people addicted to hallucinations. Many countries in Europe and the United States have banned the cultivation of marijuana for a long time. Due to the high economic value of cannabis, by the 1980s, some European countries had researched and bred low-toxic cannabis varieties and promoted their cultivation. In 1990, the European Community took the lead in urgently revising the agricultural policy, abolished the prohibition on the cultivation of hemp, and began to ...
