The bamboo cell wall breaking process includes continuous bamboo cell wall breaking in three 300 mm diameter colloid mills for coarse milling, fine milling and finish milling, softening, sterilizing, drying, ultrafine crushing, air drying and vacuum packing. The present invention is bamboo resource deep processing technology, and the produced diet bamboo fiber may be used in cake, biscuit, noodles and other food, and is suitable for patient with diabetes, obesity, etc to eat to prevent and treat diseases.

Description

The production method of bamboo meal fibre

Technical field

The present invention relates to produce behind a kind of bamboo breaking-wall cell the production method of its bamboo meal fibre.

Background technology

Fiber has a variety ofly in the food, and dietary fiber is to the necessary fiber of health, is widely used in controlling the metabolism relevant with body weight with improvement of human body body weight.Because bamboo meal fibre has extremely strong retentiveness, can absorb a large amount of moisture content, the water holding time is also long than common dietary fiber, enters dietary fiber absorption moisture content behind the digestive system and splashes bloated, the stomach feeling of repletion that is produced can prevent excessive food consumption, and reduces the absorption of heat.Dietary fiber has integration and can control absorption by human body to fat, can quicken clear row's process of intestines and improve the metabolism of metabolic system.Can utilize the characteristic food prepared therefrom of bamboo meal fibre, to diseases prevention, curing the disease and keeping healthy all is beneficial to.

Summary of the invention

The object of the present invention is to provide a kind of bamboo meal fibre tool retentiveness of utilizing strong, good water absorption, can prevent excessive food consumption, control is quickened intestines and is arranged process clearly the absorption of fat, improve the characteristic of metabolic function, use mechanical shear stress, behind breaking-wall cell, make culm obtain trickle fragmentation with the multiple devices series connection, the bamboo cell obtains continuous broken wall, and the bamboo fibre component obtains the production method of the bamboo meal fibre of high efficiency extraction.

A kind of production method of bamboo meal fibre comprises finishing, with bright bamboo raw material go the root head remove branches and leaves and culm; Fixed length makes culm sawing segmentation, and fixed length becomes 300-500mm; Spray is slightly washed, with circulation recycle-water spray irrigation repeatedly; Secondary cleaning with the water purification flushing, is removed silt, and the thing of removing contamination gets clean culm; Coarse crushing makes clean culm fragmentation, must grow the crude fibre for 3-8mm; This method also comprises following technology:

--breaking-wall cell, adopt at least three Φ 300 colloid mills series connection to roughly grind-the successive cell broken wall of fine grinding-correct grinding to broken bamboo bits, bamboo fibre is reached gradually become more meticulous, the bamboo bits cell membrane fragmentation more than 90% in the bamboo;

--the softening processing, at 90 ℃-126 ℃, under the condition of humidity 100%, the bamboo bits of broken wall are carried out 40-70 minute softening processing, make the deliquescing of bamboo bits.

--sterilizing and drying, the broken wall bamboo bits after softening are removed bamboo pulp water branch with pneumatic convey drier, make its moisture content reach 5-6%, high temperature drying sterilization under 120 ℃-140 ℃ temperature makes material obtain abundant sterilization;

--ultramicro grinding and selection by winnowing, dried bamboo slag after ultramicro grinding and selection by winnowing, obtains the bamboo meal fibre of 180-200 purpose attritive powder again.

--vacuum packaging, fine bamboo meal fibre is put into the row vacuum packaging with aluminium platinum then get product.

The colloid mill that described breaking-wall cell adopts, root diameter is Φ 300,2650 rev/mins of rotating speeds.

The present invention utilizes the bamboo raw material to produce in the process of bamboo fibre to make breaking-wall cell, and the active ingredient and nutritional labeling such as the bamboo juice etc. that are free in the bamboo powder obtain extracting, and have improved the recovery rate of the useful constituent of bamboo, are the innovative approach of bamboo comprehensive utilization; Because of the retentiveness of bamboo meal fibre strong, can adsorb a large amount of moisture, it is the necessary fiber of health, be widely used in controlling the body weight metabolism relevant with body weight, after eating, enter digestive system with improvement, adsorption moisture and the bloated stomach feeling of repletion that produces of splashing can prevent the transition feed, and the absorption of minimizing heat, can control the absorption of human body to fat, improve the metabolism of metabolic system.Therefore, bamboo meal fibre being made foods such as cake, biscuit, noodles to the effect that patients' such as diabetes, obesity special population has diseases prevention, cures the disease, keeps healthy, is good natural food raw material.

The specific embodiment

Because of culm high fiberization and lignifying, bamboo mantle marshalling and density are big, and cell membrane is hard, are difficult for by broken wall.Extract juice etc. in the bamboo and be free in active ingredient and nutritional labeling in the bamboo cell, must nutrition is free in the bamboo powder breaking-wall cell.Carry out broken wall, then adopt breaking-wall cell technology: earlier with bright bamboo raw material,, remove the root head, remove branches and leaves, make the good no detritus of culm part as finishings such as bambusa texlitis, punt-pole bamboos; The sawing segmentation is sawn into culm the fixed length of 300-500mm; The culm of fixed length is entered netted conveyer belt spray slightly and wash, with circulation recycle-water spray irrigation repeatedly; Remake secondary cleaning,, remove culm epidermis silt, remove contamination and dye foreign material with the water purification flushing; Culm after the cleaning send crusher in crushing, 460 rev/mins of this machine rotating speeds, and the mesh diameter Φ 8mm that sieves, fixed length bamboo section bamboo fibre after coarse crushing reaches 3-8mm; Three Φ 300 colloid mills series connection carrying out of bamboo crumb after fragmentation bamboo fibre broken wall, the root diameter Φ 300 of colloid mill, 2650 rev/mins of rotating speeds, be connected into the successive cell broken wall of corase grind-fine grinding-correct grinding through three colloid mills after, the bamboo bits cell membrane in the bamboo is broken more than 90%; Soften processing behind breaking-wall cell, make bamboo bits 90 ℃-126 ℃ of temperature, humidity is under 100% the condition bamboo bits of broken wall to be done 40-70 minute softening processing, makes its deliquescing; Bamboo fibre after softening with the dehydration of bamboo slag, makes its moisture content reach 5-6%, 120 ℃ of-140 ℃ of following high-temperature sterilization dryings with pneumatic convey drier; Ultramicro grinding and selection by winnowing, the bamboo slag behind the dry sterilization carries out ultramicro grinding, and makes selection by winnowing, makes it reach 180-200 purpose bamboo meal fibre; Carry out vacuum packaging with aluminide-coating bag at last, then get the bamboo meal fibre product.Prepared bamboo meal fibre, join in the foods such as cake, biscuit, noodles, after edible, can reduce the absorption of heat, fat is had integration, and can control the absorption of human body fat, and can quicken the row's process that disappears of intestines, improve metabolism, so to suffering from patients such as diabetes, obesity, the good result of treatment that diseases prevention is arranged, cure the disease and keep healthy.
