Method for preparing bamboo extract and bamboo pulp from bamboos

Abstract

The invention provides a method for preparing a bamboo extract and bamboo pulp from bamboos. The method comprises the steps that fresh bamboos are selected for pretreatment, slicing, washing, tearingand cooking, and the cooked solution and bamboo chips are separated; the solution is filtered and concentrated to enter a storage tank, and the bamboo extract or a beverage additive is prepared; the cooked bamboo chips are extruded, crushed, ground into thick liquid, deslagged, screened and concentrated to prepare various bamboo pulp products; and a filtrate obtained in the extrusion process can be reused in the bamboo extraction preparation process for treatment. The pure mechanical method and equipment are adopted, no chemical medicine is added in the whole production process, natural resources are sufficiently utilized, the production process is simple, and the prepared product is the pure natural green environment-friendly product and has the good development value and popularization prospect, wherein the bamboo extract is good in dispersity and mobility, wide in application range, low in cost and high in purity.

Description

technical field [0001] The invention relates to the technical field of deep processing of bamboo, in particular to a method for preparing bamboo extract and bamboo pulp from bamboo. Background technique [0002] China is known as the "Kingdom of Bamboo" and has very rich bamboo resources. In order to alleviate the shortage of wood, the paper industry has paid more and more attention to the research and application of bamboo raw materials, and various bamboo paper products have emerged as the times require. In recent years, the application market of natural bamboo pulp has become more and more extensive. During its processing and production, no bleaching is required, and it can be used after washing. , no odor characteristics. The traditional bamboo pulping mainly adopts the sulfate method, and more chemicals must be added to dissolve the lignin and achieve the effective separation of bamboo fibers. The yield is generally about 50%. The patent "A Device for Preparing Bamboo...

Problems solved by technology

In the prior art, the patent "Composition, Method and Application of Triterpene Total Saponins Extracted from Bamboo" (CN 1506373A) uses supercritical extraction technology to extract bamboo rutabaga, which is only carried out under laboratory conditions and cannot be produced on a large scale. At present, the processing of bamboo extract is still mainly operated by hand or simple equipment, which has high labor intensity, low efficiency, and technical defects such as high material loss rate; the patent "Method for preparing bamboo extract and bamboo pulp from bamboo" (CN105998767A) proposed A method of cooking bamboo pulp and extracting filtrate to prepare Bamboo Ruba extract, but this method and the equipment used are limited to laboratory exploration, and its process flow and parameters need to be improved, and industrial engineering production has not been realized
