Preparation method of carbonized bamboo chopsticks

Abstract

The invention discloses a preparation method of carbonized bamboo chopsticks. The preparation method comprises the following process steps that 1, a bamboo is preprocessed, wherein the bamboo is transversely sawed off in the length direction of the bamboo at intervals, and each sawed-off section of the bamboo is split into four pieces; 2, color separation and sterilization carbonization are carried out, wherein the bamboo stick products are sent to a drying and disinfecting carbonizing drying machine, the heating temperature of the drying and disinfecting carbon drying machine is 160-190 DEG C, the heating time is 2-4 hours, the bamboo sticks are carbonized, the carbonization degree of the toothpick is 5%-30%, and the toothpick is taken out; and 3, the carbonized bamboo chopsticks are prepared, wherein the obtained carbonized bamboo pieces are ground, so that flat plates are manufactured, and a chopstick forming machine is used for machining and forming.

Description

technical field [0001] The invention relates to a method for preparing carbonized bamboo chopsticks by utilizing shallow and uniform carbonized bamboo slices. The invention belongs to the technical field of bamboo chopsticks preparation. Background technique [0002] In daily life, people often use bamboo to make chopsticks. Although the cost is low, bamboo chopsticks are susceptible to mildew and deterioration due to the high sugar and water content in bamboo, and are often eaten by some pests. After bamboo chopsticks are eaten by moths, there will be uneven patterns and moths in mild cases. Although they can be used, they are not beautiful and the service life is not long. There are many anti-moth methods, such as high-temperature treatment, paint treatment, chemical treatment, etc. Although these treatment methods can achieve the purpose of anti-moth, but these methods have their own disadvantages.

Problems solved by technology

[0002] In daily life, people often use bamboo to make chopsticks. Although the cost is low, bamboo chopsticks are susceptible to mildew and deterioration due to the high sugar and moisture content in bamboo, and are often eaten by some pests.

After the bamboo chopsticks are eaten by moths, there will be uneven spots and moths in mild cases. Although they can be used, they are not beautiful and the service life is not long. In severe cases, moth holes will be formed, and the bamboo moths will be broken and cannot be used any more.

There are many anti-moth methods, such as high-temperature treatment, paint treatment, chemical treatment, etc. Although these treatment methods can achieve the purpose of anti-moth, but these methods have their own disadvantages. The glucose group in the cellulose macromolecule contained in it will undergo dehydration reaction, and its water-absorbing functional group hemicellulose will be reorganized, causing deformation of bamboo chopsticks, affecting the appearance, coating and chemical treatment will pollute the environment and be harmful to human health
