Embodiment

[0010] Mature sweet dragon bamboos are felled and stacked neatly in a quiet warehouse, properly ventilated, kept dry, and maintained at a temperature range of 15-30°C. Banna Tianlong bamboo has high sugar content and rich nutrients needed by the bamboo beetle, which is a powder-boring insect. Generally, it contains bamboo beetle eggs during the growth period. These eggs begin to develop on the felled bamboo under suitable environmental conditions. The hatched larvae start to eat by moth. On the one hand, they obtain the nutrients they need for growth and reproduction, and on the other hand, they grind and pulverize bamboo fibers into moth powder with a particle size of about 10 μm and cellulose as the main component. About 7-8 months, the bamboo beetle can grind almost all bamboo materials of Banna Tianlong bamboo except bamboo green and bamboo yellow.

[0011] Collect the bamboo beetle moth powder of Tianlong bamboo, and sieve out the bamboo beetle eggs, which is a bamboo ce...

Abstract

The invention relates to a biological grinding method for a natural cellulosic raw material which is suitable for the growth and propagation of powder-borer insects. In the method, the powder-borer insects is used and optimal growth and propagation conditions are provided to carry out large-scale cultivation; the nutrition demand of the powder-borer insects for growing development is met by smashingly boring the natural cellulosic raw material and meanwhile, the natural cellulosic raw material is ground and smashed into powder-bored cellulosic powder product with grain diameter being around 10[mu]m. The biological grinding method of the invention has low energy consumption and cost and can compete with mechanical grinding by scale merit; as the obtained products are equal to and even superior to the mechanically ground products, the efficiency of cellulose zymolysis or acid hydrolysis and alkaline hydrolysis can be improved greatly, thus being beneficial to the separation of the three components of cellulose, acid and alkaline as well as further being beneficial to deep processing so as to widen the application field. The products of the invention can also be directly used in the fields such as building materials, etc.

Description

Technical field [0001] The invention relates to a biological pretreatment method for effectively grinding specific natural cellulose raw materials suitable for the growth and reproduction of powder-boring insects, especially a biological grinding method capable of efficiently grinding and pretreating most bamboo and some wood cellulose raw materials Law. Background technique [0002] In addition to cellulose, natural cellulose raw materials also contain hemicellulose and lignin. Cellulose has amorphous and crystalline regions. It is speculated that hemicellulose mainly surrounds the amorphous region of cellulose, lignin surrounds the crystalline region of cellulose, and hemicellulose and lignin form a firmly bonded layer that surrounds cellulose. Therefore, the pores of cellulose are extremely small, the degree of polymerization is extremely high, and it is difficult to use enzymatically. [0003] People have used physical, chemical and other methods to pretreat cellulose...
