Description

A kind of bamboo prepares the method for Caulis Bambusae In Taenia extract and bamboo pulp
Technical field
The present invention relates to a kind of method that bamboo prepares Caulis Bambusae In Taenia extract and bamboo pulp.
Background technology
Bamboo is plant the highest containing triterpenoid compound on the earth, its content is more than 30 times of Ganoderma, thus be referred to as " Caulis Bambusae In Taenia triterpene " particularly major part allusion quotation bamboo by medical circle, Phyllostachys congesta, the high-load Caulis Bambusae In Taenia extract medicinal effects of blue or green bar bamboo become apparent from, lesions position can be goed deep into, directly play curative effect.Numerous researchs have shown that, triterpenoid compound has multiple biological activity, there is remarkable result in each side such as antioxidation, anticancer, anti-cancer, preventing tumor, blood fat reducing, blood pressure lowering, blood sugar lowering, prostate, cardiovascular and cerebrovascular vessel, natural function food, health product, the articles for daily use, veterinary drug can also be developed in addition to medicinal.
At present, pharmaceutical factory is to buy Chinese crude drug Caulis Bambusae In Taenia to produce extract, about 8000 yuan per ton of reasonable Caulis Bambusae In Taenia market price, 20:1 needs Caulis Bambusae In Taenia 20 tons, wanting about 160,000 yuan, cost of material adds about 20,000 yuan per ton of extraction expense, altogether money about 180,000 yuan, Caulis Bambusae In Taenia has become to give up after extracting and has removed thing, also results in resource wave and gives up.
At present, paper for daily use is produced with bamboo, during manufacturing bamboo pulp, generally requiring and be added into chemical components, one acts the waste liquid discharge produced can cause environmental pollution, and two to have on paper the residue of chemical industry, have now found that a lot of people and have dermatosis, particularly child, the gynaecopathia of women, it has been found that have much relations with toilet paper.
Summary of the invention
The problem that the invention aims to solve above-mentioned existence, it is provided that a kind of low cost, pollution-free omnidistance production reaches zero-emission, prepares the comprehensive processing method of Caulis Bambusae In Taenia extract and bamboo pulp with bamboo.
The present invention is achieved through the following technical solutions.
The present invention is a kind of method that bamboo prepares Caulis Bambusae In Taenia extract and bamboo pulp, divides fine workmanship sequence including slicing process, matting and squeezing, also comprises the following steps that:
(1), by the bamboo chip after thin for squeezing point send in vertical steam pressure stirred tank add water, after aerating steaming and decocting, by solution with squeeze bamboo chip and separate discharge；
(2), solution that will discharge from vertical steam pressure stirred tank, laid in rustless steel insulation pond by row after filter screen filtration；
(3), by the solution suction concentration pan in insulation pond, it is heated up to 100 degree and is allowed to evaporate, solution is concentrated to 60% 70%；
(4), concentrated solution is pumped into drying machine with centrifugal spray, obtains powdery Caulis Bambusae In Taenia extract, packed products after discharge after drying；
(5), will from step (1) in vertical steam pressure stirred tank discharge squeezing bamboo chip, be brought into kneading or grinding leaser by conveying, through cutter rail friction sub-wire make bamboo fibre soften；
(6), by putting in highly concentrated mill through the bamboo fibre of stranding mill sub-wire by conveyer belt, add the water of temperature 90 ~ 100 degree, make bamboo fibre decompose through high speed abrasive disc, again soften acquisition bamboo pulp；
(7), bamboo pulp is put in stirring pool, with pumping learn from else's experience slanted screen sieve take make part bamboo pulp be separated from water, water is discharged to cistern；
(8), the bamboo pulp taken off through slanted screen sieve being sent into squeezing machine, extrude moisture content 45% ~ 50%, bamboo pulp enters back into full automatic packing machine, extrudes moisture content 5% ~ 10%, and the water of extrusion is discharged to cistern, bamboo pulp finished product mass dryness fraction 50% ~ 60%.
Preferably, described bamboo through slicing process, processed after bamboo chip gauge thickness be 1 ~ 3cm, width is 2 ~ 4cm, a length of 3 ~ 4cm.
Preferably, in described step (1), bamboo chip is 3:1 with the ratio of water, and the pressure of steaming and decocting air pressure is 3 ~ 5MPa, and temperature is 140 ~ 150 degree, and digestion time is 4 ~ 6 hours.
Preferably, in described step (2), drainage screen is the stainless steel filter screen of 100 ~ 200 mesh.
Preferably, in described step (5), cutter rail friction temperature is 60 ~ 70 degree.
Preferably, in described step (6), after high speed abrasive disc rubs, it is 110 ~ 120 degree that water temperature adds friction temperature.
It is an advantage of the current invention that, owing to the present invention uses physical method to be directly cut into bamboo chip from former bamboo, Caulis Bambusae In Taenia extract and bamboo pulp is extracted from bamboo chip, objective is comprehensive production, comprehensive utilization of resources, do not cause environmental pollution, it is fully natural green environment-friendly products, by on-the-spot collection bamboo, in-site comprehensive is processed, about 1000 yuan per ton of bamboo chip of giving money as a gift, 20 tons of bamboo chips are equal to about 20,000 yuan, produce bamboo pulp about 18 tons simultaneously, extract about 1 ton, not higher than about 1.8 ten thousand yuan per ton of extract cost, contrasting us and producing extract cost is the 1 of 10 parts of pharmaceutical factory, low cost.
Accompanying drawing explanation
Fig. 1 is the process chart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
Firstly the need of doing early stage processing work, purchase more than 3 years, without mildew and rot, fresh bamboo, after microtome, processing, bamboo chip gauge thickness is 1 ~ 3cm, and width is 2 ~ 4cm, a length of 3 ~ 4cm, through over cleaning Bamboo sheet machine, mud dirt, impurity on bamboo chip are cleaned up, through the thin machine of squeezing point, bamboo chip is squeezed into Caulis Sacchari sinensis scoriform, easily steaming and decocting, easily decomposites extract, easy fiber genusization.
Previous work is ready, and the detailed process flow of the present invention is as follows:
