[0040] The raw bamboo is cut into bamboo pieces with a length of 30mm-50mm by a cutter head bamboo cutting machine, and the bamboo pieces are slowly passed through the lye pool by a belt conveyor. The time is generally 5-10 minutes, and the lye used has a concentration of 10-20 % sodium hydroxide solution, the bamboo chips in the lye pool are stacked for 24 hours to fully absorb the lye, so that the lignin between the fibers is dissolved, and then the bamboo chips that have absorbed the lye are input into the grinder, and the grinder The high-speed rotating flying blade inside cuts the bamboo material, separates the filaments, and brooms the fiber. The high-speed rotating flying blade collides with the raw material, and the friction generates a lot of heat energy to reduce the water content of the pulverized pulp from 40% to 15%. Heating and evaporating the pulp moisture can meet the pulp requirements of the drylaid paper machine and save energy.
