Embodiment 1

[0015] The drying method of the recombined bamboo and bamboo silk in this embodiment is as follows: select the bamboo material with uniform thickness, cut off the bamboo material, dissect it, and roll it out to obtain the bamboo thread, arrange it neatly and bundle it; hoist the bundled bamboo thread into a In the immersion tank of sodium bicarbonate solution with a mass fraction of 10%, adjust the temperature of the alkaline solution to 100°C, and soak for 1.5 hours; hoist the impregnated bamboo silk from the immersion tank with an electric hoist, and dehydrate naturally for 25 Minutes, then transport the bamboo silk to the carbonization furnace with a special carbonization trolley for carbonization treatment, adjust the temperature in the carbonization furnace to 150 ° C, the pressure to 4.5 MPa, carbonize for 3.5 hours, transfer to the drying kiln, set the temperature to 60 ° C , and dried until the moisture content of bamboo silk is 6%.

Embodiment 2

[0017] The drying method of the recombined bamboo and bamboo silk in this embodiment is as follows: select the bamboo material with uniform thickness, cut off the bamboo material, dissect it, and roll it out to obtain the bamboo thread, arrange it neatly and bundle it; hoist the bundled bamboo thread into a In the immersion tank of sodium bicarbonate solution with a mass fraction of 10%, adjust the temperature of the alkaline solution to 100°C, and immerse for 2 hours; hoist the impregnated bamboo silk from the immersion tank with an electric hoist, and dehydrate naturally for 35 Minutes, then transport the bamboo silk to the carbonization furnace with a special carbonization trolley for carbonization treatment, adjust the temperature in the carbonization furnace to 170 ° C, the pressure to 3.5 MPa, carbonize for 4.5 hours, transfer to the drying kiln, set the temperature to 65 ° C , dried to a moisture content of 9%.

Embodiment 3

[0019] The drying method of the recombined bamboo and bamboo silk in this embodiment is as follows: select the bamboo material with uniform thickness, cut off the bamboo material, dissect it, and roll it out to obtain the bamboo thread, arrange it neatly and bundle it; hoist the bundled bamboo thread into a In the immersion tank of sodium hydroxide solution with a mass fraction of 10%, adjust the temperature of the alkaline solution to 100°C, and soak for 1.8 hours; hoist the impregnated bamboo silk from the immersion tank with an electric hoist, and dehydrate naturally for 45 Minutes, then transport the bamboo silk to the carbonization furnace with a special carbonization trolley for carbonization treatment, adjust the temperature in the carbonization furnace to 130°C, the pressure to 2.7 MPa, carbonize for 2.5 hours, transfer to the drying kiln, set the temperature to 70°C , dried until the moisture content of the bamboo silk is 12%.

Abstract

The invention discloses a drying method for bamboo filaments of recombined bamboo and relates to the technical field of bamboo. The bundled bamboo filaments are transferred into a steeping pool of an alkaline solution with the pH value being 9-13 to be steeped; and then the bamboo filaments are taken out from the steeping pool, natural dehydration is conducted, then carbonization treatment is conducted, and finally drying is conducted. The strong alkaline solution is used for steeping the bamboo filaments under a high temperature, part of starch in the recombined bamboo is hydrolyzed, and protein in the recombined bamboo is denatured, then a high-temperature carbonizing method is used for making starch in the recombined bamboo hydrolyzed more thoroughly and protein in the recombined bamboo denatured more thoroughly, insects such as fungi lose nutrition sources, meanwhile, worm eggs and fungi in the bamboo are killed, and therefore the phenomenon that the recombined bamboo is prone to moth growth and mildew is avoided, and the quality of the recombined bamboo is better. A special bamboo filament drying kiln is used for drying, and the drying period is shorter.

Description

technical field [0001] The invention relates to the technical field of bamboo, in particular to a drying method for recombined bamboo shreds. Background technique [0002] China is the country with the richest bamboo resources in the world. Its bamboo species, bamboo forest area, and stock volume all occupy the top of the world. It is known as the "Kingdom of Bamboo". The growth period of bamboo is short, and once the bamboo forest is cultivated, it can provide bamboo continuously. Therefore, the development and utilization of recombined bamboo is a practical and feasible way to solve the shortage of furniture materials in our country. [0003] Recombined bamboo has a natural woody feel, with fine grooves in the shape of wood pipes on the surface, and the surface texture is natural and smooth, full of changes and various colors. According to product modeling needs, it can also be dyed into various material colors. The touch of restructured bamboo is the same as that of woo...
