Abstract

The present invention discloses a bamboo powder processing technology which comprises the following procedures: the crushing and the cutting-off of raw bamboos or waste bamboo materials, drying, sterilization, pulverization, milling and finished product packing. Additionally, the temperature of the drying and the sterilization is controlled between 88 DEG C and 280 DEG C, a water ratio of the waste bamboo material or a raw bamboo block is controlled between 1% and 16% after the drying, after a bamboo powder semi-finished product of which the product granularity is less than 40 meshes or the diameter is 1.2 millimeters and the length is more than 3.0 millimeters is obtained by the pulverization of a pulverizer and then put into a flour mill to be milled, so a dry bamboo powder finished product from 40 meshes to 200 meshes is obtained. The product of the present invention has the advantages of high water ratio, uniform granularity, no mould occurrence, stable quality, low cost, easy use, obvious effect and good economical benefit.

Description

Bamboo flour producing process

Affiliated technical field:

The present invention relates to the bamboo deep process, particularly a kind of bamboo flour producing process.

Background technology:

The bamboo powder is got after mechanical comminution drying by bamboo.The bamboo powder is natural, green, can be used as the raw material of electrical part, welding rod, bamboo charcoal, also can be used as reducing agent of metallurgy industry or the like, its remarkable environmental function just more and more is subjected to the attention of all trades and professions, and the raw material sources of making the bamboo powder are extensive, comprise that all use bamboos to do remaining tailing in the enterprise of raw material, produce in the process thick and the bamboo powder that can not directly use.Bamboo flour producing process is immature at present, directly sell after normally pulverizing with the beater grinder processing that grinds fodder, because its moisture content instability, without high temperature sterilization, be prone to go mouldy, infested phenomenon, and its thickness inequality, the 30%th, the granularity of spherical shape is more than 40 orders, the 70%th, columned diameter is more than 0.10 millimeter, length is at 1.0～3.0 millimeters, and as sieving reprocessing to this product, not only cost is very high, and brought bigger difficulty to use, restricted the application of bamboo powder.

Summary of the invention:

The objective of the invention is to be intended to overcome above-mentioned shortcoming, a kind of new bamboo flour producing process is provided, the moisture content scope of its final products is stable, and epigranular is not gone mouldy, the equal quality condition, cost is low, and is easy to use, and effect is remarkable, solved like this and used bamboo to do the waste problems of the enterprise of raw material, improved economic benefit of enterprises simultaneously.

Technological process of the present invention is: the broken cut-out of former bamboo or bamboo waste, dry sterilization, pulverizing are ground, finished product packing.

Concrete processing step of the present invention is as follows:

A, former bamboo or bamboo waste are broken to cut off: former bamboo is depressed into the former bamboo piece of the square or bar shaped of being cut into the 5-150 millimeters long then of breaking, or selects pure bamboo waste for use, be cut into the bamboo piece of 5-150 millimeter.

B, dry sterilization: directly bamboo waste or former bamboo piece are sent into the dry sterilization of drier with artificial or mechanical system, baking temperature is controlled at 88 ℃～280 ℃, and the moisture content of dry back bamboo waste or former bamboo piece is controlled at 1%～16%;

C, pulverizing are ground: bamboo waste after the dry sterilization or former bamboo piece are sent in the pulverizer by artificial or mechanical mode of movement, after obtaining product granularity and be following or 1.2 millimeters of the diameters of 40 orders, the bamboo powder semi-finished product of length more than 3.0 millimeters, send in the flour mill again and grind, obtain the dry bamboo powder of 40～200 purposes finished product.

D, finished product packing: with there being the Polywoven Bag of inner membrance to carry out finished product packing.

Should note environmental sanitation in the production process of the present invention, can not sneak into any impurity, otherwise influence quality, damage machine, security incident takes place; Exhausting-dusting prevents dust explosion; Select for use bamboo cutter, drier, drying room, beater disintegrating machine, flour mill, baling press will note the matters such as supporting linking of each operation, the bamboo powder finished product matters that in stock and transportation, guard against damp etc.

The moisture content of product of the present invention is stable, can in 1-16%, adjust arbitrarily, epigranular is adjusted arbitrarily between the 40-200 order, and is not gone mouldy, the equal quality condition, cost is low, and is easy to use, and effect is remarkable, solved and used bamboo to do the waste problems of the enterprise of raw material, improved economic benefit of enterprises simultaneously.

The specific embodiment:

A, former bamboo or bamboo waste be broken to cut off: former bamboo is depressed into the former bamboo piece of the square or bar shaped of being cut into the 20-30 millimeters long then of breaking, or selects pure bamboo waste for use; Tip and hard object matter such as stone, metal sand can not be arranged in the bamboo waste, impurity such as plastics, wood chip can not be arranged, the kind of bamboo is not limit; The blade type bamboo cutter that the cutting of breaking can adopt the paper mill to use, available conveyer belt connects drier.

B, dry sterilization: directly bamboo waste or former bamboo piece are sent into the dry sterilization of drier with artificial or mechanical system, baking temperature is controlled at 120 ℃, and the moisture content of dry back bamboo waste or former bamboo piece is controlled at 6-8%; Drier rotary drier or drying room etc., decide on the moisture content of raw material and size, shape, baking temperature and the dried water content requirement of raw material drying time, and the used thermal source of drier can be available other thermals source such as hot blast, coal, electricity, steam, hot water.

C, mushroom is ground in pulverizing: bamboo waste after the dry sterilization or former bamboo piece are sent in the pulverizer by artificial or mechanical mode of movement, obtaining product granularity is below 40 orders, or diameter 1.2-3 millimeter, behind the bamboo powder semi-finished product of length 3.0-8 millimeter, send in the flour mill again and grind, obtain the dry bamboo powder of 40～200 purposes finished product, pulverizer adopts beater disintegrating machine, the semi-finished product that obtain through beater disintegrating machine have cutter head with artificial or mechanical mode of movement feeding, cutterhead, the classification fan blade is arranged, the flour mill that the air flow recovery device is arranged, the order number of its bamboo powder is adjustable on this flour mill, and order number and output are inversely proportional to.

D, finished product packing: with there being the Polywoven Bag of inner membrance to carry out finished product packing.Polywoven Bag directly pack on flour mill of inner membrance is arranged, or bamboo powder finished product introduced the baling press charging door from the material grinder discharging opening with artificial or mechanical mode of movement, in the vanning of baling press, put well bag weavedly in advance, with the mode of pressure packing the bamboo powder is implemented pressure and pack.

When the present invention selects former bamboo for use, can after dry sterilization, directly grind, and not need pulverizing process.

The moisture content of product of the present invention is stable, can in 1-16%, adjust arbitrarily, epigranular is adjusted arbitrarily between the 40-200 order, and is not gone mouldy, equal quality, cost is low, and is easy to use, and effect is remarkable, solved and used bamboo to do the waste problems of the enterprise of raw material, improved economic benefit of enterprises simultaneously.
