Description
Technical field
The invention belongs to the deep process technology field of konjaku, especially a kind of method that konjaku powder is refined into konjaku micropowder.
Background technology
The Main Ingredients and Appearance of konjaku powder is Portugal's mannose, is broad-spectrum food additives.
Because smart powder particles is thicker, granularity generally is coarser than 80 orders (being generally 40. orders-80 order), and viscosity discharges very slow, generally wants just can reach about two hours high viscosity, uses cumbersome in process of production; For viscosity is discharged rapidly, used in a large number easily, the konjaku powder grain refine need be become the littler micro mist of particle diameter.
The high resilience because the konjaku powder particle is hard, refinement is very difficult, and Japan has spent also do not solve decades.Middle nineteen nineties grandson inventor optical valley etc. has been invented the softening smart powder particles of a kind of employing low concentration (35%) ethanol (organic inhibitor), then in the presence of organic inhibitor ethanol, by common colloid mill (wet method refinement processing) just can reach refinement purpose, make konjaku micropowder (Chinese invention patent ZL94111753).This technology of domestic a large amount of employings is at present produced konjac glucomannan (konjaku micropowder), and export volume is big.
According to the konjac glucomannan quality better of this method use alcohol production, the purity height, viscosity discharges fast.But the cost of refinement is too big: the one, and the ethanol use amount is big, and konjac glucomannan use amount per ton reaches more than one ton, and ethanol reclaims best enterprise also will be with more than 0.6 ton, and a large amount of ethanol volatilizees or drains with waste water; The equipment of recovered alcohol is big, the expense height; The 2nd, material loss is big, and general loss reaches more than 20%; The 3rd, the waste water and dregs treating capacity is big, generally produces one ton of konjac glucomannan and produces about 10 tons of waste water, about 0.2 ton in waste residue.The unable processing waste water and dregs of present most konjaku processing enterprise has caused the pollution to environment.
In order to overcome the shortcoming of wet method refinement processing, the dry method refinement technology is directly powerful broken with high-power milling apparatus, grinds repeatedly, thereby material is pulverized.Its cost is lower, can adapt to the demand of domestic low-end market, thereby be promoted rapidly.But the product quality of this technology is not high, can't satisfy the demand of field, the particularly international market higher to the food additives quality requirement.Subject matter is that degree of refinement is not high; Production efficiency is low, and every unit per hour only can be processed about 20 kilograms of micro mists; Power consumption is big, and power consumption per ton reaches about 1000 degree.Even more serious is because the general severe overweight of the smart powder sulfur content of China, and dry process is detergent powder not usually, and not desulfurization is so the micro mist sulfur content still exceeds standard; Human body is produced potential hazard.
Summary of the invention
Main purpose of the present invention is at above-mentioned problems of the prior art: wet method refinement processing cause the ethanol consumption big, reclaim not exclusively, the equipment of recovered alcohol is big, expense is high, material loss is big, the waste water and dregs treating capacity is big, and environmental pollution etc.; The degree of refinement of dry method refinement technology is not high, product quality is relatively poor, production efficiency is low, power consumption is big, the general severe overweight of sulfur content produces potential hazard etc. to human body, and a kind of new method that konjaku powder is refined into konjaku micropowder is provided, can significantly reduce the ethanol consumption, thereby reduce cost of material and cost recovery etc., and degree of refinement height, good product quality, production efficiency height, simultaneously lower, the harmful material such as sulfur-bearing not of energy consumption.
In order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
A kind of konjaku powder is refined into the method for konjaku micropowder, comprises following key step:
(1), swelling is softening:
Get 40 orders-80 purpose konjaku powder particle,, make the water content of konjaku powder particle be about 30%-70% with being equivalent to the softening konjaku powder particle of konjaku powder particle weight 0.5-2.5 water swelling doubly;
(2), grind:
Konjaku powder particle after again step (1) swelling being softened ground 3-5 minute with grinder, promptly obtained granularity and was narrower than 120 purpose konjaku micropowders.
In the above-mentioned steps (1), the addition of water can be preferably 0.5-1.5 times of konjaku powder particle weight.At the described water that is used for the softening konjaku powder particle of swelling, also can further add organic resistance solvent and/or inorganic resistance solvent.Described organic resistance solvent can be ethanol and/or isopropyl alcohol; Its addition is that 10-30% calculates with its concentration of volume percent in water.Described inorganic resistance solvent can be trisodium citrate; Its addition is that 1-10% calculates with its mass percent concentration in water.
In the step (2), the grinder that is used to grind can be preferably Kun formula grinder.
Specifically, when the konjaku powder particle is ground, need not add inhibitor liquid; The separation of also need not dewatering after the konjaku powder grain refine.
In the research process of swelling method refinement konjaku powder of the present invention, the inventor finds: Portugal's mannose cell of forming smart powder particles has very strong water imbibition, after the suction, and the rapid swelling of particle, it is big that volume becomes, the quality deliquescing.Along with water absorption increases, volume becomes greatly thereupon, and when cell membrane was not also broken, viscosity generally can not discharge, and the water absorption of this moment is exactly the suitable water consumption of softening smart powder.The so-called softening state that is not clamminess with regard to being meant Portugal's mannose particle to be in swelling.This moment, broken smart powder particles was the easiest, the most laborsaving.
Compared with prior art, the invention has the beneficial effects as follows:
Compare with the wet method thinning method that prior art is common, both all need softening smart powder particles, and its difference mainly contains 2 points: first, in the common wet method, in process of lapping, in order to keep mobile, at least will have the liquid medium about three times to participate in, this has just increased the use amount of ethanol; The swelling rule does not need liquid medium to participate in.The second, the smart powder of common wet method needs to separate with centrifuge dewatering after the colloid mill refinement again, removes desizing, SO
2Deng impurity; On this link, be easy to generate two problems, the one, more inner solable matters (as nutriments such as reduced sugar, protein, fat) are easily lost (about 6-8%) after the smart powder particles fragmentation when dehydration, the 2nd, produced a spot of superfine smart powder particles in the colloid mill process of lapping, be as good as with impurity granularities such as starch, also together lost, so the material loss rate reaches more than 20%; And swelling method of the present invention is earlier konjaku powder particle (sulfur dioxide and impurity content are high) to be washed, refinement then, and the surface of the smart powder particles of just washing cleaning, inner solable matter is separated out less; After grinding refinement, need not dehydration again and separate link, do not have superfine smart powder particles and lose, therefore, both can save the ethanol consumption significantly, can significantly reduce the loss of raw material again.
Compare with the dry method thinning method of prior art: do the refinement method and generally do not wash the smart powder of cleaning, softening smart powder particles, but adopt brute force broken, and be difficult to guarantee the high-quality of micro mist, consume more electric power resource again.And swelling method of the present invention cleans the surface of smart powder particles earlier with an amount of water, and smart powder particles is softened in back swelling, and the water content that makes smart powder particles is about 30%-70%, uses Kun formula grinder at an easy rate with smart powder particles refinement again, reaches the national standard of konjac glucomannan.Be fit to konjac mannan sugar granular biological and learn characteristics, both can guarantee the konjac glucomannan quality, can reduce cost again, raise the efficiency, economize on resources protection environment etc.
In addition; the advantage of swelling method refinement of the present invention also has: the technical process of swelling refinement is simple; equipment needed thereby is less; productivity ratio obviously improves; fixed assets drop into and day-to-day maintenance reduces; the waste water and dregs treating capacity greatly alleviates, and is favourable to the protection environment, meets the industrial policy of national energy-saving and emission-reduction.
