NOVELTY - Biological bacterial degumming of raw hemp comprises pulping, filtering, removing dust of the raw hemp, inputting raw material after the dust is removed into a container, adding potassium hydroxide aqueous solution, soaking, quickly absorbing and swelling; and inputting the swelling raw materials into an extruding machine for draining, draining material and conveying the fungus liquid pool or tank, and soaking.    USE - Method for biological bacterial degumming of raw hemp (claimed).    ADVANTAGE - The method is simple and environment-friendly, has low production cost, saves water and electricity with high efficiency and high yield cellulose, and can realize zero discharge of the industrial process.    DETAILED DESCRIPTION - Biological bacterial degumming of raw hemp comprises pulping, filtering, removing dust of the raw hemp, inputting raw material after the dust is removed into a container, adding potassium hydroxide aqueous solution with the concentration of 0.5-0.6 wt.%, where the solid-to-liquid mass ratio is 1:7, the temperature is more than 60 degrees C, soaking for 2 hours, quickly absorbing and swelling; and inputting the swelling raw materials into an extruding machine for draining, where the water content of the raw material is controlled at 28-32 wt.%, draining material and conveying the fungus liquid pool or tank, and soaking for 12 hours, where the temperature is controlled at 35-40 degrees C, every 5 hours for 1 time. The bacteria liquid is rot, soft rot fungi, yeast, and four different bacterial strain including the composite bacterial liquid according to the mass ratio of white rot fungus to soft rot bacteria to wood bacteria to yeast of 1:1:1:2. The density of bacteria is not less than 6000 million/ml. The material is soaked to transmit into the bacteria liquid for cleaning the bacterial liquid in the washing tank.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic flow diagram of the method for biological bacterial degumming of raw hemp (Drawing includes non-English language text).
