Abstract
The main drawback of traditional phytic acid manufacture method is: energy consumption is big, environmental pollution is serious, operation is many, complex process, yield poorly, of poor quality, some auxiliary materials source shortage and waste material can not fully utilize etc.
The present invention is directed to above-mentioned shortcoming, a kind of new phytic acid manufacture method has been proposed, its master operation is: with salt acid soak raw material, with hydrochloric acid dilute luxuriant and rich with fragrance spit of fland, with hang the filter legal system get Fei Ting and thick phytic acid, with activated carbon decolorizing, use resins exchange, concentrated with the vacuum decompression method, obtain phytic acid at last.
Description
The present invention is the manufacture method of phytic acid.
Phytic acid is a kind of good oxidation inhibitor, no toxic agent.It is widely used for fields such as food, detergents and cosmetic, chemical industry, medicine, oil and light and textile industries.Traditional manufacturing phytic acid method is: make raw material with rice bran, wheat bran or corn, transfer pH value with sulfuric acid, again through immersion, manufacturing procedures such as neutralization filtration, separation, displacement, last concentration extraction and getting.
This traditional manufacture method exists following shortcoming: 1. soak with sulfuric acid, the intensification value is little.Especially at low temperature season, must heat, be not less than 60 ℃ to keep the acidleach temperature, otherwise influence output.2. sulfuric acid is strong oxidizer, meets air and carbonic acid gas and can produce violent oxidizing reaction, thereby reduced acid number, has influenced output.3. need to use large quantities of lime, cause in the phytic acid ca calcium-magnesium content excessive, thereby influenced the refining workload in later stage, also increased energy-output ratio, increased cost.4. because of the need heating, cause the thick phytic acid of a part in heat-processed, to be evaporated, also reduced output.5. some auxiliary material belongs to goods and materials in short supply, the buying difficulty.6. dilute luxuriant and rich with fragrance spit of fland with oxalic acid, its shortcoming increases energy expenditure for needing heating, replaces not thoroughly, and refuse is many, and efficient is low.7. produce filtrate with centrifugal separation, its shortcoming is: because speed is too fast, cause the filtrate muddiness, strengthened the precision work workload in later stage, also influenced the quality of phytic acid.8. the waste material of gained can not fully utilize.
The objective of the invention is to overcome above-mentioned tradition and produce the existing shortcoming of phytic acid method, propose a kind of new method of producing phytic acid, concrete technology is as follows:
Rice bran or wheat bran are dropped in the acidleach cylinder, add quantitative water, add hydrochloric acid again, transferring pH value is 2, and acidleach was measured the temperature of acidleach water about 4 hours, and normal circumstances should be and heats up about 6 ℃.Filter then, in the filtrate input cylinder, add saturated milk of lime again, accents pH value is 3.5-5, is 7.5 with saturated caustic soda soln accent pH value again, treats luxuriant and rich with fragrance spit of fland post precipitation, takes out clear water with siphonage, change ordinary water and wash, when the upper water colorless and odorless till.When Fei Ting becomes pure white look, add the pure water washed twice again, then dehydration.Drop in the displacement container in luxuriant and rich with fragrance spit of fland after will dewatering again, and adding hydrochloric acid accent pH value is that 2(requires quick and precisely, makes Fei Ting be the clear water sample), filter then, promptly get thick phytic acid.
Advantage of the present invention is: 1. change traditional sulfuric acid infusion method into the hydrochloric acid infusion method, can save the operation of heating of low temperature season, thereby save the energy, reduce steam output, increase output.2. this law is diluted luxuriant and rich with fragrance spit of fland with hydrochloric acid, has overcome with oxalic acid to dilute the shortcoming that bring in luxuriant and rich with fragrance spit of fland.3. hydrochloric acid belongs to monoprotic acid, oxygen-free own, and oxidation susceptibility is extremely low, thereby, the acid number height of maintenance, output is also high.4. owing to the acid number height, the molecular structure of raw material will be destroyed, and promote organic acid to ooze out, and increase output.5. this law lime consumption is few, and environmental pollution is little, and can reduce the workload of post-production, improves the quality of product.6. this law changes centrifugal separation into and hangs the filter method, has overcome filtrate muddiness, later stage precision work workload is big, quality product is low shortcoming, and has saved the energy.7. the spent caustic water of present method gained can fully utilize.
In a word, the method for producing phytic acid proposed by the invention is compared with traditional method, has that technology is simple, operation is few, cost is low, equipment is simple, output is high, quality is good and waste material such as can fully utilize at advantage.
Embodiment:
(1) acidleach, neutralization:
Get 100 kilograms in rice bran or wheat bran, put into the acidleach cylinder, add 500 kilograms in water, transferring pH value with 6 kilograms of hydrochloric acid is that 2(transferred 1～3 minute), acidleach is filtered about 4 hours then again, and filtrate must reach transparent degree.
Pour in the cylinder filtrate standby.Add 400 kilograms in water in filter residue, add 2 kilograms of hydrochloric acid again, transferring pH value is 2, and acidleach refiltered about 4 hours, and filtrate must reach transparent degree, then, abandons filter residue (can make feed).Again twice filtrate is combined (amounting to about 600 kilograms), transferring pH value with saturated limewater or milk of lime is 3.5, transferring pH value with saturated caustic soda soln again is 7.5, the clear liquid on siphon upper strata after 5 hours, change the ordinary water washing, the water on siphon upper strata changes water once again after 5 hours, till when supernatant liquid is colourless, tasteless, transparent, the luxuriant and rich with fragrance spit of fland of gained is pure white look.Through hanging filter, dehydration, can obtain Fei Ting then.
(2) displacement
Add 2 kilograms of hydrochloric acid at Fei Tingnei, transferring pH value is 2, requires quick and precisely, when treating that Fei Ting is the clear water sample, hangs filter, promptly gets thick phytic acid.
(3) decolouring
Add gac in thick phytic acid, decolour, the weight of gac is 2% of thick phytic acid weight, heats then to 60 ℃, keeps constant temperature 30 minutes.Cooled off again,, promptly obtained the thick phytic acid of water white transparency shape with vacuum decompression method suction filtration.
(4) exchange
The thick phytic acid of decolouring is placed in the exchange column, exchanges, reach outward appearance and get final product for the water white transparency shape with resin.
(5) concentrate
Adopting the way of vacuum decompression to concentrate the phytic acid that exchanged, be concentrated to concentration and be 70% and get final product, is that little yellow, transparent, sediment-free are as the criterion with outward appearance, and this is the phytic acid of producing.
