Description
Technical field
The method of raw sugar remelt syrup clarification decoloration, belongs to foods processing technique in refining sugar the present invention relates to a kind of two step method
Field.
Technical background
With the development of the society, people are higher and higher to the quality requirements of sugar.Particularly the colour of sugar, purity,
Ash content etc., common arable land level-one white granulated sugar can not meet the demand in market already.Sugar refinery mainly uses two at present
Footwork produces refined sugar, and technical process is：Raw sugar after honey is washed, dissolving, be passed through carbon dioxide, add milk of lime into
Row full charge, full charge has certain decolorizing effect, while the syrup after full charge is filtered by plate and frame filter press, can remove most of
Impurity.Syrup after full charge cleans by resin decolorization again, obtains affination syrup, syrup colour at this time reach 30IU with
Under, by evaporization process, the syrup for obtaining 65 ° of Bx directly sends to Zhu Tang workshop sections.Since country increasingly payes attention to environmental protection now,
The bittern that resin produces is since containing higher COD value and BOD values, colourity is higher, and directly discharge causes environment very big dirt
Dye, current processing mode allow bacterial degradation to discharge into biochemistry pool, this method take it is longer, due to the needs of production, usually
1000 tons of raw sugar are handled, can at least produce 600 tons of bittern, amount is very big, and discharge also is difficult to up to standard.
Ceramic membrane is a kind of using ceramic material as the film made of medium with separation function.The separation process of ceramic membrane is
Using film as filter medium, when material liquid flows through film surface, only allow water, inorganic salts, small-molecule substance to pass through film, and prevent former
The macromolecular substances such as suspended matter, colloid and microorganism in feed liquid are by so as to fulfill the purpose of clarification.Ceramic membrane is physics mistake
Journey is filtered, while a large amount of impurity are removed, and the characteristics such as the original flavor of material can be retained well, so ceramic membrane is a large amount of
Apply in juice is clarified and is degerming.Activated carbon is due to fabulous decolorizing effect, being widely used in food industry.
During refined sugar technological development, also once decolourized using activated carbon to liquid glucose, but due to activated carbon cost compared with
Height, is slowly substituted by other discoloration methods.With the development of science and technology the recovery process of activated carbon is more and more ripe, it is used
Activated carbon, by certain treatment process, can achieve the purpose that recycling, thus it is of high cost the problem of met sword and
Solution.
Therefore, it is applied to if activated carbon can be coupled ceramic membrane filter system in the production technology of purified sugar, can
Gradually to substitute the workshop section of carbon full charge and plate-frame filtering, the colour of obtained syrup can reach 50IU once, then coordinate ion to hand over
Pigment and inorganic salts that resin removes ionic are changed, evaporation sugar boiling workshop section can be gone directly to.A large amount of regeneration for reducing resin time
Number, and then the discharge capacity of bittern is reduced, the service life of resin is effectively improved, production cost is reduced, effectively reduces to environment
Pollution.
The content of the invention
The object of the present invention is to provide a kind of raw sugar remelt syrup to clarify discoloration method, and producing refined sugar for two step method provides
New clarification decoloration process, can effectively improve production efficiency, reduce production cost and the pollution to environment, improve the warp of sucrose
Ji value.
To achieve these goals, present invention employs following technical scheme：
A kind of method of raw sugar remelt syrup clarification decoloration, comprises the following steps：
(1) honey is washed：Hydro-peening is carried out to raw sugar using honey centrifuge and molasses, removes large granular impurity and the part on raw sugar surface
Pigment；
(2) dissolve：By raw sugar or by honey wash after raw sugar with hot water dissolving to 45~65 ° of Bx, be heated to 60~80
DEG C, insulation；
(3) activated carbon adsorption：Add relative to the activated carbon that dry solids content is 0.1~2%, reacted at 40~80 DEG C
20~40min, obtains remelt syrup；
(4) ceramic membrane filter：Remelt syrup is filtered using the ceramic film component that average membrane pore size is 0.005~0.5 μm, is obtained
To clear syrup, the operating parameter of ceramic membrane is：Transmembrane pressure is 0.10~0.50MPa, and crossflow velocity is 2.0~5.0m/s, behaviour
Make temperature as 20~80 DEG C；
(5) ion-exchange resin decolorization desalination：The clear syrup obtained from ceramic film component juice opening is sent into the first ion and is handed over
Change resin tower to decolourize, obtain the first penetrating fluid；The first penetrating fluid is sent into the second exchange resin tower again and carries out desalination,
Obtained penetrating fluid is the refinery liquor that decolourizes.
Dissolving, activated carbon adsorption storage tank described in step (2), which carry, is slowly stirred device.
The first ion exchange resin described in step (5) is macroporous strong basic anion exchange resin.
The second ion exchange resin described in step (5) is handed over for storng-acid cation exchange resin or Subacidity cation
Change resin.
Compared with prior art, the beneficial effect that the present invention possesses：
(1) in the clarification decolorization of remelt syrup, with physical methods of filtration, any chemical reagents are not added, are ensured
Food it is green safe.Because the characteristic of ceramic membrane in itself, resistance caused by fouling is smaller, and the flux of ceramic membrane is larger, raw
Produce efficient, reduce full charge and add the cumbersome of Investigation on Plate Filtration, without buying the lime and diatomite of food-grade, it is real to meet production
Apply on border.
(2) ceramic membrane can reach the removal rate of the large granular impurities such as starch and pectin 100%, the removal rate energy of protein
Reach 80%, moreover it is possible to retain a small amount of pigment, be effectively reduced the pressure of rear stage resin, reduce the regeneration times of resin, strengthen
The service life of resin, reduces production cost, is smoothed out the production in rear stage.
(3) ceramic membrane and activated carbon coupling use, and reduce the load of exchange resin tower, when colour is up to standard even
It can disable, reduce hydrochloric acid, the usage amount of caustic soda of discharge and the regeneration of resin bittern, reduce the pollution to environment.
(4) used activated carbon can reduce work again by being recycled after some simple process
The purchase cost of property charcoal, and pollution of the solid waste to environment.
(5) price of import raw sugar is low, can be former by the use of second-rate raw sugar as production with ceramic membrane as filter medium
Material, reduces the prime cost of technique, improves the economic value of sucrose.
(6) whole technique does not use sulphur decoloration additionally, and the detected level of the sulfur dioxide of the refinery liquor of acquisition is few, symbol
Close limitation of the food security to sulfur content in the world.
