Problems solved by technology

But the fatal weakness of this natural fresh stem degumming method is that it is seriously restricted by natural conditions, especially in Heilongjiang Province in autumn with low temperature and little rain, which leads to long degumming cycle, inconsistent degumming degree, uneven degumming of processed fibers, poor spinnability, and reduced It affects the market competitiveness of fiber products and affects the development of industrial hemp industry

specific Embodiment approach 1

[0025] Specific embodiment one: in this embodiment, the original stem degumming method of industrial hemp is carried out through the following steps:

[0026] Step 1, bundling the dried hemp original stems into a 25cm-diameter bar to obtain the original stem bundles;

[0027] Step 2. Then use a criss-cross pattern to stack on flatbed trucks with a length of 5m and a width of 2m. The interval between two adjacent bundles on each layer is 25mm. Each truck is stacked with 20 bundles horizontally and 20 bundles vertically, with 6 layers of stacking, and then pulled to the plastic greenhouse. in the shed;

[0028] Step 3. Under natural light conditions, control the humidity in the plastic greenhouse at 65%, and control the temperature at 33±2°C. Under natural light conditions, when the sun is sufficient and the indoor temperature exceeds 35°C, it should be ventilated in time. Turn off the ventilation when it drops to about 25°C, and observe the degree of degumming at any time. Whe...

Abstract

The invention discloses an industrial raw-cannabis-sativa-stem degumming method, and belongs to the technical field of agricultural product processing. The industrial raw-cannabis-sativa-stem degumming method saves energy, is environmentally friendly and efficient and overcomes the defects of a traditional warm-water cannabis-sativa retting method and the defects of a natural fresh-stem rain and dew degumming method. The industrial raw-cannabis-sativa-stem degumming method includes the steps that raw cannabis-sativa stems are bundled, soaked with water and stacked in a room of a plastic greenhouse or directly covered with a light transmitting plastic film, and the raw cannabis-sativa stems are degummed under the conditions that natural lighting is kept, the temperature is controlled to be 15-35 DEG C, and the relative humidity is controlled to be 50%-75%. The method is not limited by sites, the technology is convenient to master, the degumming period is short, efficiency is high, production can be carried out in Heilongjiang province except for winter, and industrialization of raw stem degumming can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a method for degumming the original stems of industrial hemp; the invention is used for degumming the original stems of industrial hemp fibers before processing, specifically, the original stems of industrial hemp are bundled, soaked in water, and then According to the technical requirements, it is stacked in the shed of the plastic greenhouse or directly covered with a light-transmitting plastic film, under the condition of natural light, and the suitable temperature and humidity are controlled to complete the degumming method of the original hemp stem. Background technique [0002] Hemp (Cannabissativa L.), also known as thread hemp, hemp, hemp, etc., belongs to the Cannabis family Cannabis genus annual herb, and is one of the ancient fiber crops in my country. The hemp currently grown as a textile raw material is called industrial hemp, whic...
