Production method for co-production of functional sugar by high-durability heavy bamboo boards

Abstract

The invention discloses a production method for co-production of functional sugar by high-durability heavy bamboo boards, and belongs to the technical field of bamboo processing. Cutting, breakage, green removal, yellow removal and rolling are performed on bamboos to obtain bamboo filament bundles; the bamboo filament bundles, water and a functional sugar extracting auxiliary are added in a horizontal cooking boiler for heating and cooking to selectively dissolve out the functional sugar; and desugared and carbonized bamboo filament bundles and functional sugar raw sugar liquid are obtained bysolid-liquid separation. The bamboo filament bundles obtained by the method can be used for producing high-durability outdoor landscape materials and indoor home materials; and the cooking liquid obtained by the method can be used for producing functional oligosaccharide. The defects of easy ignition, generation of waste liquid and smoke and the like in a traditional high-durability bamboo charring process are prevented in the whole production process; and meanwhile, the sugar liquid is changed from wastes to the wealth, so that the bamboo processing additional value is improved. The method also can obtain the bamboo filament bundles with different color systems through adjusting cooking parameters and controlling the charring degree; and in addition, as hydrothermal cooking carbonizationis adopted, the treatment strength is uniform, the chromatic aberration of bamboo chips is reduced, and the board beauty is improved.

Description

technical field [0001] The invention relates to a bamboo processing technology, in particular to a production method for co-producing functional sugar from high-weight bamboo boards. Background technique [0002] China is very rich in bamboo resources, with more than 500 species. It ranks first in the world in terms of area, storage volume, output of bamboo products and export value. It is known as the "Kingdom of Bamboo". According to the "National Bamboo Industry Development Plan" issued by the State Forestry Administration, by the end of 2010, the national bamboo forest area reached 6.7274 million hectares, and the total number of standing bamboos was 28.635 billion. The area covered by bamboo in Fujian Province alone is as high as 3.26 million mu, and the annual bamboo output exceeds 1.2 million tons. The growth cycle of bamboo is short, with an average of 3 to 5 years. In addition, bamboo grows densely and is easy to collect. It can be collected all year round without ...

Problems solved by technology

However, the deep carbonization of "high-resistance bamboo boards" needs to be carried out under high temperature conditions. If the control is not good, it is easy to catch fire. The carbonization process will also produce waste liquid and a large amount of smoke; Bamboo color, which limits the development of high-resistance bamboo board industry
