Description
Technical field
The present invention relates to sugar refining field, the method that sugared material is boiled in especially a kind of processing that improves sugaring raw material sugar recovery.
Background technology
In the production process of sugar refinery, it is to boil sugar, crystallization in motion, purging and drying process that the sugar refining technology of white sugar generally comprises raw material extraction of the juice, clarification, evaporation, three, wherein, three is that high-grade massecuite, intermediate massecuite and the raw massecuite obtaining in Boiling Process sieves out honey, commerieal sugar through crystallization in motion, purging respectively, screening sweet purity is out not high, for not affecting quality product, the general honey time of only part first being washed boils high-grade massecuite, another part is as the material of back segment massecuite boiling, make to move after material, reduced the withdrawal of sugar.The purity of sugaring material is higher, and Sucrose is higher, and impurity is fewer, and the easier crystallization of sucrose absorbs, and the recovery of Sucrose is just higher.And current sugar refining technology only carries out clarify process and improves feed purity boiling glycogen material before being Boiling Process three.Existing sugar refining technology material clarify process includes and after raw material extraction of the juice, carries out clarifying treatment, to the clear juice processing of floating after clarification, and the processing of floating of the syrup after evaporization process.Due to factor impacts such as raw material " non-sucrose " impurity component and number change, physical and chemical properties change, existing way are unstable, production operation fluctuation, the purification effect limit, make a large amount of " non-sucrose " impurity fail to remove and enter Boiling Process.These " non-sucrose " impurity one are to hinder sucrose molecules crystallization, regain low; The 2nd, increase material viscosity, regain low; The 3rd, massecuite, molasses are swollen cause to emit case or molasses spontaneous combustion; The 4th, in molasses, inorganic ash content content is too high, has significantly reduced utility value, brings serious potential safety hazard to environment simultaneously.
Summary of the invention
The object of this invention is to provide a kind of sugaring and boil the method for sugared material clarify process, this method can solve existing sugar refining technology and boil the large and sugar of the foreign matter content of sugared material and regain low problem.
In order to address the above problem, the technical solution used in the present invention is: the method for sugared material clarify process is boiled in this sugaring, and its step is as follows:
A, dilution: be that the honey that massecuite that in Boiling Process, boiling obtains sieves out through crystallization in motion, purging dilutes by three, be diluted to 60 Bx ~ 70Bx;
B, heating: the honey after dilution is heated to 70 ℃ ~ 80 ℃;
C, floating: the heating honey that pressurized air is passed into the step B floating of getting blisters in floating device, clears out the foam of floating;
D, sedimentation: be uniformly mixed reaction with the calcium hydroxide of phosphoric acid and 1.0 ~ 1.2 phosphoric acid equivalents and removed in the honey of foam and formed the sedimentation of secondary calcium phosphate-calcium phosphate network with step C, add again the suspended particle impurity sedimentation in the auxiliary absorption of flocculation agent honey, obtain clearly syrup as boiling sugared raw material.
Above-mentioned sugaring is boiled in the technical scheme of method of sugared material clarify process, and technical scheme can also be more specifically: the sediment producing in step D is carried out to centrifugation, and the clear syrup obtaining is as boiling sugared raw material.
Further, described phosphoric acid consumption is 400 ppm ~ 2400ppm, and described flocculation agent consumption is 1.5 ppm ~ 10ppm.
Further, described honey is that high green syrup, first are washed honey, second green molasses, second and washed a kind of in honey, molasses or wherein several.
Preferably, flocculation agent is polyacrylamide.
The principle of technical scheme of the present invention is three to be the high-grade massecuite boiling in sugar, intermediate massecuite, raw massecuite is through boiling, crystallization in motion, purging honey is out separated out after a large amount of Sucroses because of it, " non-sucrose " impurity moiety is stable, physico-chemical property is stable, calcium sulfate, Calucium Silicate powder, magnesium salts etc. are at 60 Bx ~ 70Bx, in the liquid glucose of 70 ℃ ~ 80 ℃, solubility product declines, the characteristic that the overwhelming majority exists with suspended particle, material is removed organic surface-active substance (foam) through floating, add again the compound sediment of secondary calcium phosphate-calcium phosphate that phosphoric acid and milk of lime reaction generate, under flocculation agent booster action, form network sedimentation absorption catch material in suspended state particle inorganic, organic " non-sucrose " impurity.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, process by floating, can effectively remove surfactant class " non-sucrose " organic impuritys such as phospholipoprotein mixture, pectin, composite gel, reduce the crystallization of sucrose factor that hinders, reduce material viscosity, improve feed purity, regain thereby improve Sucrose;
2, eliminate intermediate massecuite, raw massecuite, waste molasses swell problem and waste molasses spontaneous combustion problem;
3, add secondary calcium phosphate-calcium phosphate and be aided with the absorption of flocculation agent effect formation network, sedimentation, centrifugation, can effectively remove the inorganic ash content in material, reduce the crystallization of sucrose factor that hinders, improve feed purity, improve Sucrose withdrawal;
4, improve 8 AP ~ 13AP through the feed purity of clarify process, major part can be returned and be boiled, and has reduced back segment material boiling amount, improves Sucrose and regains, and reduces molasses productive rate;
5, in the molasses after clarify process, inorganic ash content content is extremely low, promotes the utility value of molasses.
