Problems solved by technology

[0004] The common problems of the above-mentioned technical solutions are: the conversion rate of bamboo, the output rate are low and there is waste or waste water, such as making pulp, which is easy to produce waste water and waste, which pollutes the environment relatively large. With the improvement of China's environmental awareness , due to the high cost of waste and wastewater treatment, this adds a large economic burden to the paper mill for subsequent treatment
In the above-mentioned prior art, no matter it is bamboo pulping or bamboo extracts bamboo leek, all is to utilize bamboo raw material to produce single product---paper pulp (fiber) or bamboo leach, all can produce waste and waste water, and the comprehensive utilization rate of its bamboo is relatively low, The resource value of bamboo has not been fully realized

Embodiment 1

[0035] Such as figure 1 Shown, a kind of preparation method of producing bamboo pulp fiber and bamboo extract with bamboo, its method is as follows:

[0036] A, pretreatment of fresh bamboo stalks: collect fresh bamboo stalks of Grass plants that are 1 to 2 years old, and remove branches and leaves on the fresh bamboo stalks to form fresh bamboo stalk raw materials. Eliminate moth-eaten and spotted bamboo stalks for fresh bamboo stalks; transport the fresh bamboo stalk raw materials to the bamboo slice cutting machine through the belt conveyor and cut them into fresh bamboo slices. The length of each fresh bamboo slice is controlled at 40-120 mm; the fresh bamboo The bamboo chips are transported to the bamboo chip washing machine by the belt conveyor for washing, and the washed fresh bamboo chips are torn into fine bamboo silk materials, and the diameter of the bamboo silk materials is less than 2 mm.

[0037] B. Steaming and decocting treatment of bamboo silk material: send ...

Abstract

The invention discloses a preparation method and use of bamboo pulp fibers and bamboo extracts from bamboo, which includes pretreatment of fresh bamboo poles, steaming and decoction of bamboo shreds, first enzymatic treatment, softening treatment, high temperature Through thick refining treatment, pressing treatment, second enzymatic hydrolysis treatment and concentration treatment, the present invention can simultaneously extract bamboo pulp fiber and bamboo extract, reduce the generation of waste and wastewater in bamboo pulping, and redesign the process method. The bamboo extract can be effectively and comprehensively extracted, and can be converted into medicinal and edible materials. It can remove most of the sugars, tannins and other impurities that affect the quality of bamboo pulp fiber, and reduce the amount of bamboo pulp fiber. The non-ferrous substances in the bamboo improve the utilization rate and output rate of bamboo.

Description

technical field [0001] The invention relates to the technical fields of pulping and papermaking, pharmacy, food and feed, in particular to a preparation method and application of bamboo pulp fiber and bamboo extract from bamboo, in particular to a bamboo extract and bamboo pulp fiber and their joint preparation The process method is suitable for making full use of fresh bamboo. Background technique [0002] Bamboo is a high-quality fiber raw material, and China is also the first country to use bamboo to make pulp and paper. Bamboo leek in fresh bamboo is another kind of traditional Chinese medicinal material. Its medicinal value has been recorded as early as in "Compendium of Materia Medica". Fresh bamboo leek has a sweet smell and is non-toxic. Blood, stop boredom, quench one's thirst and other effects, recorded in the first volume of "Chinese Materia Medica" (1992). With the development of modern science and technology, through continuous exploration, fresh bamboo leek h...
