Description
Technical field
The present invention relates to cane sugar manufacture technology field, particularly relate to a kind of cane sugar manufacture defecation method using ozone decolorization technology.
Background technology
China is third place in the world Chan Tang big country, sugar annual production in recent years more than 1,000 ten thousand tons, is wherein raw material with sugarcane more than 90%.Current China cane sugar manufacture is produced more than 95% and is used sulfurous method clarification process, namely uses SO
2as primary clarifying agent, at the Ca of clarifying process and milk of lime
2+reaction generates the CaSO with strong adsorption-edulcoration
3precipitation, will be had the non-saccharide such as colloid, pigment to adsorb coprecipitation, then they removed by solid-liquid separation technique, improve sugarcane juice purity and reduce sugarcane juice colour in sugarcane juice; SO simultaneously
2also can cause color substance generation addition reaction with sugarcane juice phenol sulfonate, reducing sugar alkaline decomposition intermediate product etc. with unsaturated link(age), play bleaching, suppress new pigment nucleus formation.
In general, SO
2removal of impurities decolorization in sugarcane juice is strengthened with the increase of its consumption.Therefore SO
2in sulfurous method Closed Circulation in Sugar Production, be in irreplaceable position, since in October, 2006, China implemented white sugar new nation standard, vast sugar enterprise is by improving SO always
2consumption (intensity of sulfitation) comes to realize reducing white sugar colour object.
But due at traditional clarifying process, whole process control is at neutral range, and SO
2the H that dissolved water generates
2sO
3be weak diacid, be difficult to this understanding completely secondary ionization and Ca occur
2+generate CaSO
3precipitation, therefore unavoidably has part SO
2in a variety of manners in residual clear juice; Meanwhile, because sugarcane juice itself is a complicated component and the very strong system of variability, contained colloidalmaterial can hinder SO
2with Ca
2+reaction, make SO in juice clearly
2content increases.Remain in juice sulfurous gas clearly, in syrup boiling process, White Sugar Crystal inside can be entered into by sucrose crystal absorption, parcel, increase white sugar SO
2content.
SO in white sugar
2mainly exist with sulphite form, slowly can be transformed into sulfurous gas in storage and edible process, the Digestive tract of infringement human respiratory tract, eyes, human body, hepatic tissue and lymphsystem etc., therefore white sugar SO
2content height relates to sugar security, and there is strict demand in man of China to this index, if white sugar SO
2content is forbidden dispatching from the factory more than 30mg/kg.Domestic and international famous brand name food and drink are to white sugar SO simultaneously
2content requirement is very harsh (SO always
2content higher than 15mg/kg, even can not contain SO
2), therefore China's white sugar major part cannot enter this great market at present, largely weakens China's white sugar market competitiveness, affects China's sugar industry development.
Therefore, how to reduce its SO in reduction white sugar colour simultaneously
2content is one of China's sugaring circle study hotspot always.
Summary of the invention

Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Because most sulfurous method sugar enterprises of current China custom is by improving SO
2consumption reduces white sugar colour, but SO
2the increase of consumption may cause SO in juice clearly
2content increases, thus causes white sugar SO
2content raises, and affect white sand confectionery safety, cartogram understands granulated sugar colour and SO
2exceeding standard is the large factor of China's White Sugar Quality underproof two.
In view of this, one of core idea of the embodiment of the present invention is, uses ozone Some substitute SO
2clarify and decolorize process is carried out to sugarcane juice, thus can SO be reduced
2consumption, reduces white sugar SO
2content.
Specifically, embodiments provide a kind of cane sugar manufacture defecation method, have employed traditional sulfurous method clarification process, traditional sulfurous method clarification process comprises pre-ash process, heat treated, second-heating process, a solid-liquid separation process, Sulphitation and Neutralization process and the process of secondary solid-liquid separation, the embodiment of the present invention, after a heat treated, adds and adopts ozone to carry out the step of decolouring.
Tradition sulfurous method is mainly by SO
2sugarcane juice is decoloured, the embodiment of the present invention adopts ozone to decolour, ozone has strong oxidizing property, ozone and the pigment produced in Active Radicals Produced (OH) sugarcane juice thereof or cause unsaturated link(age) fracture contained by color substance in the solution, generate the colourless or light material of small molecules, reach decolorizing effect, compared to SO
2cane sugar manufacture clarifying process decolorizing effect can be improved; Further, after adding the step of ozone decolorization, SO when carrying out Sulphitation and Neutralization
2consumption can reduce, and can reduce production cost on the one hand, the SO that another aspect uses due to Sulphitation and Neutralization process
2amount reduces, SO in white sugar
2residual quantity can greatly reduce, sugar security can be improved.
The step of ozone decolorization process can perform after mixing juice heat treated before a solid-liquid separation process, can perform before Sulphitation and Neutralization process after mixing juice heat treated, also can perform before process of floating after syrup heating.Specifically, can perform between mixing juice heat treated and second-heating process, also can perform between the process of mixing juice second-heating and a solid-liquid separation process, also can perform between second-heating process and a solid-liquid separation process, can perform between a solid-liquid separation and Sulphitation and Neutralization process, specifically select to perform and can design according to concrete demand and applied environment between any two steps.
