Description
Technical field
The present invention relates to the manufacture craft of crystalline dextrose, particularly a kind of method of producing crystalline dextrose with rice.
Background technology
At present; Generally with raw material production crystalline dextroses such as corn, wheat, Ipomoea batatas, cassavas, ripe not enough with rice as the technology of raw material, but since in the rice contained starch granules less than corn, wheat, Ipomoea batatas, cassava etc.; Be about 2-10um, only greater than oat.And the size of starch granules is a factor of decision gelatinization speed, the little then gelatinization easily of particle, particle greatly then is not easy gelatinization, therefore be badly in need of having a kind of sophisticated be that the method for raw material production crystalline dextrose is come out with the rice.
Summary of the invention
To the deficiency of above-mentioned similar technology, the purpose of this invention is to provide a kind of method of producing crystalline dextrose with rice.
Making method of the present invention may further comprise the steps:
(1) soak defibrination: after rice washing totally, adjust to basic soln after immersion for some time with soda ash, with the emery wheel defibrination, fineness is more than 60 orders;
(2) size mixing: 17-19Be ° of the concentration of sizing mixing, transfer pH value 5.8-6.0 with soda ash and hydrochloric acid, add calcium chloride 0.2-0.5 kilogram by dry-matter per ton, add a-fire resistant alpha-diastase 400ml-550ml again, stir and sent into liquefaction transfer jar in 30 minutes;
(3) slag is taken off in liquefaction: adopt the liquefaction of efficient low pressure ejector will, 105 ℃-110 ℃ of injection temperatures get into pressurize and keep jar pressurize about 5 minutes; The flash distillation cooling is sent into continuous liquefaction streamline column for 95 ℃, guarantees albumen flocculation, liquefaction thoroughly, 90-110 minute laminar flow time; Detect the DE value and reach 15%-20%; Iodine try into brown or iodine liquid true qualities after, again through the second spraying device, the flash distillation cooling is 115 ℃-120 ℃ behind 125 ℃ of-130 ℃ of enzymes that go out of controlled temperature; After taking off slag transfer jar and cooling to 95 ℃-100 ℃, adopt chamber(filter)press to filter and take off slag with the logical cold water of coil pipe;
(4) saccharification: the sugar material is cooled to 58 ℃-60 ℃ and delivers to saccharifying tank; Transfer PH4.0-4.4 with hydrochloric acid; Measure sugar material concentration and volume; Calculate every jar of dry substance mixture; Add carbohydrase by 800ml/ ton-1200ml/ ton dry, saccharification 40-60 hour, the dextrin reaction was qualified; Behind DE value >=95%, be warming up to 80 ℃ of-85 ℃ of enzyme dischargings of going out with injector;
(5) once neutralization filter, in the secondary and filter: after one time neutralizing tank receives the sugar material; Survey pH value; Transfer to 4.4-4.8 with hydrochloric acid or soda ash; Temperature is controlled at 80 ℃-90 ℃; Press 3kg/ ton dry and add craboraffin; Stirred 30 minutes; Sampling is filtered with test paper; Can use box filter to filter when color and luster reaches water white transparency or little yellow, carry out in the secondary again and filtration, method is with once neutralization filtration; Just secondary filter adopts airtight filter to filter; Feed liquid requires as clear as crystal, no foreign matter, the visible impurity of no naked eyes;
(6) IX: with exchanging the sugar material from the friendship post, discharging clarification, water white transparency, free from extraneous odour, transparence >=95%, pH value 4.0-6.0;
(7) concentrated making with extra care: with the falling film type quadruple effect evaporator sugar material is concentrated to 70%-72%, delivers to three bleachers and add gac stirring 30 minutes, filter with the closed filter, concentrate totally no foreign matter, no carbon granules is delivered to the preceding transfer jar of crystallization;
(8) crystallization:
Charging: thoroughly clean crystallizer; And cool off subsequent use after 30-50 minute naturally with the steam high-temperature sterilization to crystallizer; Feeding temperature is reduced to 45-50 ℃ with plate type heat exchanger; Be fed to for the first time crystallizer 30%; Jar is interior as no crystal seed; Adding finished product glucose more than 4% by advancing sugared dry keeps 12 hours growing the grains of 45 ℃ of temperature, and crystal seed is cultivated good back and advanced the sugared material of crystallizer full for the second time;
Crystallization: after crystallizer sugar material advances to expire, start stirrer and stir more than 4 hours, 0.6 rev/min of rotating speed is measured DE value, DS value, pH value, according to measuring effect, calculates saturation ratio, amount of water; Prevent that spontaneous nucleus from forming, and influences crystallization effect; Crystallization time 48-60 hour, adopt the curve cooling method, 4 ℃ of coolings in per 12 hours, final crystallization crystal is even, not sticking the stirring, it is obvious that hand is pinched particle, but 27 ℃ of right and left dischargings of temperature;
Centrifugal: even discharging during discharging; Crystallizer can not go out; Stay 25%-30% as crystal seed; Washed 30 seconds with deionized water when rotating speed 600 changes after the centrifuge charging; Vapour was washed 10 seconds when rotating speed 900 changeed, and with deionized water washing 20 seconds, guaranteed that green molasses thoroughly separates with crystal when rotating speed 1040 changes; Centrifugal back crystal grain rule, pure, moisture content≤14%;
(9) oven dry: adopt the oven dry of hot gas flow drying system; About 110 ℃ of temperature, charging is even, and wind speed is an amount of; Moisture content is controlled at about 8%; Getting into the cold air stream drying system then, lead to 10 ℃ in the copper aluminium radiator--20 ℃ of refrigerated waters are cooled to about 20 ℃, guarantee that finished product glucose crystal does not destroy, do not lump.
When raw material is Jie Mi or thin rice, before soaking the defibrination step, increase a cleanup step: select for use chaff crushed rices separation sieve to sift out chaff powder and rice husk, remove other impurity with stoner again.
Advantage of the present invention: the crystalline dextrose absorptivity that the inventive method is produced is strong, hypoallergenic, and biological value is high; Has the incomparable advantage of other starch glucose; Through adopting high temperature liquefaction, three decolourings and refining, crystallizer high-temperature sterilization from handing over; Steps such as finished product sterile packed have been guaranteed product quality and food safety.The present invention can also be the raw material production crystalline dextrose with joint (carefully) rice, has solved general of present joint (carefully) rice and has sold as feedstuff raw material, and its value is not fully utilized; The defective of the wasting of resources, the present invention is with joint (carefully) metric system glucose, and joint (carefully) Mi Ziyuan obtains maximum using; Added value of product is high, and rice aboundresources of same time (carefully) can satisfy the production needs; And safeguarded national food safety, belong to country and advocate and the support industry.
