Bamboo chopstick processing method

Abstract

The invention discloses a bamboo chopstick processing method. The bamboo chopstick processing method comprises the following steps: a bamboo is sawn to a bamboo cylinder; the bamboo cylinder is processed to a bamboo piece, and is processed to a bamboo chopstick blank; one end of the bamboo chopstick blank is sharpened; the wet disinfection and the blenching are performed; the preservative treatment is performed; the carbonizing treatment is performed; the drying and the disinfection are performed; the polishing is performed; and the sorting and the packing are performed. Compared with the mildew prevention and the disinfection of chopsticks smoked by sulfur and boiled by hydrogen peroxide, the bamboo chopstick processing method is safer and more reliable; as ozone cannot leave any poisonous substances on the chopsticks, and an ozone disinfection method saves more energy, the excellent mould preventing, bleaching and disinfecting effects can be obtained only by consuming less electric energy without needing heating; bamboo chopsticks are dip in paraffin liquid or tung oil under high temperature, so that the corrosion preventing effect of the chopsticks in later use is effectively guaranteed; the bamboo chopsticks prepared by the method has such performances as corrosion prevention, insect prevention, mildew prevention and damp prevention, and such natural colors as faint yellow and brown are given to the bamboo chopsticks; and the bamboo chopstick processing method increases the mechanical degree, quickens the production speed, and improves the production efficiency.

Description

technical field [0001] The invention relates to a processing technology of wood, in particular to a processing method of 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. The chemical composition of bamboo is basically the same as that of wood, mainly cellulose, hemicellulose, lignin and extractive substances. 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 additives are often used in the processing, such as food-grade sulfur and food-grade sodium metabisulfite. Excessive use of these additives will lead to excessive microbial indicators and residual indicato...

Problems solved by technology

The heavy metal lead in the paint and the organic solvent benzene are carcinogenic. Moreover, with the wear and tear in use, once the paint on the chopsticks falls off, it will enter the human body with food, which will seriously endanger people's health.
