Detailed description of the invention
Fig. 1: the flow diagram of the present embodiment 1.
Specific embodiment
A kind of method for preparing extract and bamboo pulp with bamboo, specifically comprises the following steps: disclosed in the present embodiment
(1) the fresh bamboo that water content is 30%-65% is chosen, is impregnated by preceding preprocessor, dust, impurity on removal bamboo chip.
Bamboo chip is processed via drum slicer, and bamboo chip gauge thickness is less than 15mm, width 5-20mm, length 20-60mm.At slice
Bamboo chip after reason is transmitted to cleaning machine through conveyer belt, and the impurity in bamboo is cleaned with pure water.Bamboo chip after cleaning is torn through screw extrusion
Machine processing is split, bamboo chip is squeezed into tearing fasciculation, clusters shape, so as to high temperature and pressure boiling and hydrolysis bamboo extractive.(2) will
Resulting bamboo chip is delivered to pressure cookers after previous step tearing point is thin, and the pressure of boiling air pressure is 0.1-3.0MPa, temperature
It is 100-350 DEG C, digestion time 0.5-10h, during which repeatedly small deflation is separated solution and bamboo chip after boiling with eliminating false pressure
Discharge.
(3) solution that step (2) digesting apparatus is discharged is cooled to 10 DEG C -100 DEG C, carries out coarse filtration.First filtering removal meat
Eye visible field trash, such as bamboo particle, bamboo ash, the broken cauline leaf of bamboo etc..Contain soluble protein, fruit with membrane filter method removal again
The substance of glue, starch makes up to the feed liquor requirement of next step.Filtered solution enters storage tank, solution concentration 1%-
2%。
(4) the filtered solution of previous step is concentrated using reverse osmosis membrane, so that the water in solution passes through infiltration
The infiltration of film opposite direction, dehydration is condensed into the solution of concentration about 4%-30%, then carries out multiple-effect evaporation, system using multiple-effect falling film evaporator
At the solution of different cocnentration factors, solution of the solute concentration range after 30%-80%, concentration enters fluid reservoir.Using multiple-effect evaporation,
The original color of bamboo extractive, smell can be retained to the maximum extent, earning rate is high, cleans, is easy to maintain, it can be achieved that continuous
Change, industrialized production.
(5) concentrate that concentration is 30%-50% in the concentrate obtained for previous step, using centrifugal spray drying skill
Art obtains powdery bamboo extractive, can be applicable to the industries such as food, medicine, farthest utilizes forest resourceies, bright obtaining
While aobvious economic benefit, developing fast growing wood papermaking to China has great guidance and reference function.Previous step is obtained
Concentrate in concentration be 70%-80% concentrate, for beverage additive is made, the additive have both nutrition fortifier,
The multiple functions such as immunopotentiator, lipid metaboli regulator, remarkable in economical benefits.
(6) bamboo chip that step (2) digesting apparatus is discharged is delivered to screw extruder, extrusion dehydration to mass dryness fraction 25%-40%,
Filtrate after shove returns to for bamboo extraction process, i.e. step (3) to step (5) is handled.Residue is delivered to crusher
It after broken, being delivered to high-density paste mill and carries out defibrination, be 15%-30% into slurry concentration, decompose bamboo fibre, softening is slurried again,
Slurry enters stock tank, i.e. eliminating potential pool after mill；Slurry pumping in eliminating potential pool to double disc refiner is subjected to atmospheric refining runs, it is dense into starching
Degree is 3.5%-4.0%, and wire-dividing broom purification bamboo fibre improves interfibrous binding force, increases beating degree.Slurry enters stock tank after mill,
Being stirred continuously using stock trough agitator, which prevents fiber from wadding occurs, gathers.
(7) slurry concentration that previous step enters stock tank is diluted to 2%-3%, pump dense hydrocyclone into is gone
Sand grains, ring, crude fibre, wax except the weight impurity in slurry, such as in thick slurry.After slagging-off, it is screened and purified processing removal
Exogenous impurity and small part fibre bundle are 2%-3% into slurry concentration.Tail slurry enters sediment case, and good slurry enters next step and handles.
(8) the good slurry for obtaining previous step is pumped to thickener, and sizing concentration 2.5%-3%, thickener can be according to slurry
Expect that concentration selects double net concentrators or screw extruder.Good slurry is concentrated by natural-dehydration-extrusion dehydration, dehydration to 30%-
Bamboo pulp product is made in 50% mass dryness fraction.The good slurry of previous step can also be used for papermaking, and the good slurry pulp quality after screening is good, can subtract
Fault in production in few paper-making process, the higher paper of production mass and cardboard.
The present embodiment selects screw extrusion shredder to carry out extruding tearing to bamboo in step (1), and bamboo chip is in helicla flute
Interior, with the rotation of helical axis, the diminution of helicla flute volume, bamboo chip is extruded, tears, most of air, moisture, portion in bamboo chip
Dividing water-soluble substances outflow, bamboo chip is squeezed in screw extruder, is sheared, stretched and is reversed the comprehensive function of various power,
So that bamboo chip is shredded into fine debris along its grain direction, generate many crackings, bulk density becomes smaller, and structure becomes loose, increases
The specific surface area of bamboo chip is more advantageous to the dipping of hot water to obtain content higher bamboo extractive, while reducing in defibrination
The energy consumption of high-density paste mill in the process.
The present embodiment selects pressure cookers in step (2), using replacement cycles process flow and pure water system, hot water
It is constantly recycled in boiling vessel, so that raw material comes into full contact with hot water, improves the recovery rate of bamboo chip content, in digestion process not
Add any chemical substance.
