Abstract
The invention is a glucose crystallization operating process, and its character: it adopts step crystal growth, step by step, pours the syrup made by liquefying, saccharifying, refining and concentrating in a crystallizing kettle with a stirrer and corresponding adds in crystal seeds, preserves the heat and grows the crystals in each step, and controls to lower the temperature according to the crystallization curve to crystallize. It can make uniform crystallization, uneasy to form broken crystals and false crystals, thus enhancing the crystallizing effect, largely saving the crystal seeds, reducing the production cost and providing a feasible way for producing alpha-glucose monohydrate.
Description
Technical field
The present invention relates to a kind of production method of glucose, particularly a kind of crystallization one water α-Pu Taotang crystallization operation technology.
Background technology
Glucose is the penta hydroxy group hexanal that obtains through the starch hydrolysis, because its good to eat sweet taste and abundant medicinal and nutritive value are accepted by people already, is widely used in food, medicine and other fields.
The glucose industrial production need pass through liquefaction, saccharification, refining, concentrate, operations such as crystallization, separation, drying and packing, wherein Crystallization Procedure is exactly the process that the DEXTROSE MONOHYDRATE BP crystal is separated out from the syrup that above-mentioned enrichment process makes.From the shown crystallization curve of glucose crystallization phasor as can be known, under state of saturation, the glucose of solid phase exists with different isomer with the difference of temperature.Be a water α glucose below 50 ℃, 50 ℃～115 ℃ is anhydrous α glucose, is anhydrous beta glucose more than 115 ℃.In the water α glucose process of production, 50～45 ℃ of the syrupy supplied materials temperature of crystallization job position request supersaturation, 48～44 ℃ of growing the grain temperature, crystallization cooling temperature are 44～42 ℃.It is the formation of nucleus and the growth of nucleus that crystallization mainly divides two stages, and both normally carry out simultaneously.In Jie surely distinguishes, can only there be the nucleus of minute quantity to generate, mainly be the growth of original nucleus, but after adding crystal seed, can impel nucleus formation and growth; In the unstable regin, the generation of nucleus can be carried out simultaneously with growth.
The crystallization of period 1 sugar is generally adopted and add crystal seed seeding, the method for decrease temperature crystalline more earlier in syrup in the industrial production.Tradition shop crystal seed method is: disposable injection crystallizer 20～22m
3The supersaturation syrup is poured one ton of crystalline glucose then into, begins decrease temperature crystalline behind the stirring growing the grain certain hour.But exist crystallization inhomogeneous, form problems such as broken grain, pseudo-crystalline substance easily; It is too many to consume crystal seed in addition, thereby increases workload and production cost.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art and a kind of new glucose crystallization operating procedure is provided, it can make crystallization even, stable crystal form, thus guarantee quality product, reduce production costs.
Purpose of the present invention can realize by following technical measures: the present invention adopts the substep growing the grain, to inject the crystallizer that has agitator step by step through liquefaction, saccharification, syrup refining, that make after concentrating, and corresponding substep with syrup adds crystal seed, per step is incubated growing the grain respectively, controls decrease temperature crystalline afterwards.
The each injection rate of syrup is that crystallizer uses volumetrical 15%～35%, and the crystal seed add-on is 30～50kg/m
3Syrup.
For simplifying technology, reduce production costs, its growing the grain was divided into for two steps, and the first step syrup injection rate is that crystallizer uses volumetrical 20%～30%, and the crystal seed add-on is 35～45kg/m
3Syrup is incubated growing the grain between 46～44 ℃, rearing crystal time is 10～14 hours, and more satisfactory is 12 hours; The second step syrup is identical with the first time respectively with the crystal seed input amount, is incubated growing the grain between 45～43 ℃, and rearing crystal time is 10～14 hours, and more satisfactory is 12 hours; Then syrup is filled with crystallizer, naturally cool to 44～42 ℃, begin to finish Crystallization Procedure by crystallization curve control decrease temperature crystalline.
Massecuite fermentation for suppressing may cause because of shop crystal seed cycle lengthening adds Sodium Pyrosulfite (Na
2S
2O
5) saturated aqueous solution, add-on is 0.1～0.2L/m
3Syrup.
Described crystal seed is crystallization one molasses sugar.
The present invention adopts substep growing the grain method to replace traditional growing the grain method, can make crystallization even, be difficult for forming broken grain, pseudo-brilliant, thereby improved crystallization effect, alleviate throwing crystal seed workload, saved crystal seed greatly, reduced production cost, for the production of a water α-Pu Taotang provides a kind of practicable approach, thereby the favorable industrial using value is arranged.
