Embodiment 1

[0022] Saw the bamboo into sections, split the pieces, and make bamboo strips. The bamboo strips are processed into bamboo chopsticks with a chopstick forming machine.

[0023] Place the processed bamboo chopsticks in a concentration of 1% Na 2 S 2 o 5 In the solution for 30 hours; take it out and soak it in clean water for 5 times. Dry the bamboo chopsticks at 80-120°C to keep the moisture content below 10%.

[0024] Arrange the bamboo chopsticks neatly, place them in the carbonization furnace, pass in water vapor, control the pressure of the carbonization furnace to 0.18~0.2Mpa, and the temperature to 128~135°C, and carbonize for 3 hours. Take out the bamboo chopsticks and dry them.

[0025] The carbonized bamboo chopsticks after drying can be polished and other treatments.

Embodiment 2

[0027] Saw the bamboo into sections, split the pieces, and make bamboo strips. The bamboo strips are processed into bamboo chopsticks with a chopstick forming machine.

[0028] Place the processed bamboo chopsticks in a concentration of 2% Na 2 S 2 o 5 In the solution for 24 hours; take it out and soak it in clean water for 5 times. Dry the bamboo chopsticks at 80-120°C to keep the moisture content below 10%.

[0029] Arrange the bamboo chopsticks neatly, place them in the carbonization furnace, pass in water vapor, control the pressure of the carbonization furnace to 0.18~0.2Mpa, and the temperature to 128~135°C, and carbonize for 1.5 hours. Take out the bamboo chopsticks and dry them.

Embodiment 3

[0031] Saw the bamboo into sections, split the pieces, and make bamboo strips. The bamboo strips are processed into bamboo chopsticks with a chopstick forming machine.

[0032] Place the processed bamboo chopsticks in 1.5% Na by mass percent concentration. 2 S 2 o 5 In the solution for 28 hours; take it out and soak it in clean water for 5 times. Dry the bamboo chopsticks at 80-120°C to keep the moisture content below 10%.

[0033] Arrange the bamboo chopsticks neatly, place them in the carbonization furnace, pass in water vapor, control the pressure of the carbonization furnace to 0.18~0.2Mpa, and the temperature to 128~135°C, and carbonize for 2 hours. Take out the bamboo chopsticks and dry them.

Abstract

The invention discloses a method for manufacturing carbonized bamboo chopsticks, which comprises the steps of: sawing bamboo into sections, splitting pieces to make bamboo strips; processing the bamboo strips into bamboo chopsticks with a chopstick forming machine; placing the processed bamboo chopsticks on a mass The percentage concentration is 1~2% Na2S2O5 solution for 24~30 hours; take it out and soak it in clean water for 4~5 times; dry the bamboo chopsticks at 60~120°C to make the moisture content below 10%; The bamboo chopsticks are stacked neatly, placed in the carbonization furnace, and water vapor is introduced, the pressure of the carbonization furnace is controlled at 0.18~0.2MPa, the temperature is 128~135°C, and carbonization takes 1.5~3 hours; take out the bamboo chopsticks and dry them. Carbonizing bamboo chopsticks under high temperature and high pressure can carbonize all nutrients such as insect eggs, fat, sugar, and protein in the bamboo material, fundamentally eliminate the living space of insects and bacteria, and make the material lighter. Arranged in the shape of "hollow bricks", the tensile and compressive strength and waterproof performance are greatly improved. The bamboo chopsticks prepared by using the invention have properties such as anti-corrosion, insect-proof, mildew-proof and moisture-proof, and the bamboo chopsticks have beautiful and consistent colors.

Description

technical field [0001] The invention belongs to the field of bamboo product processing, in particular to a method for manufacturing carbonized bamboo chopsticks. Background technique [0002] Chopsticks are common daily necessities that people use in their daily lives. Chopsticks made of natural materials mainly include wooden chopsticks and bamboo chopsticks. [0003] The chemical composition of bamboo is basically the same as that of wood, mainly cellulose, hemicellulose, lignin and extractive substances. But bamboo contains more protein, sugar, starch, fat and wax than wood, so it is vulnerable to insects and fungi when the temperature and humidity are suitable. [0004] In the prior art, bamboo chopsticks are essentially different from disposable wooden chopsticks in the processing procedure due to the characteristics of high water content and perishability of bamboo itself. In order to ensure the freshness and beautiful appearance of bamboo chopsticks, some food addi...
