Abstract
The processing method of production refined sugar of the present invention, spent ion exchange resin or gac or both all are not used for handling syrup, but after retro-dissolved syrup filtered through carbonation, produce refined sugar thereby adopt the phosphoric acid floating method further to handle.Make have in this way equipment simple, easy and simple to handle, save advantages such as material, cost are lower.
Description
The invention belongs to the processing and manufacturing of sugar.
Produce refined sugar at present, generally adopt the method for raw sugar recrystallization.The external raw sugar of sucrose part 96% or more that normally will contain returns melt into retro-dissolved syrup (or behind the multiple earlier sieve Hui Rong) again, through after certain peace and quiet processing, through ion exchange resin or gac or both all further desalination decolouring processing of usefulness, boiling becomes refined sugar then again; Domestic then is with behind the white sugar Hui Rong, handles capable boiling refined sugar through the decolouring of ion exchange resin or gac again.All these produce the processing method of refined sugar, and its desalination decolouring is handled and generally all be unable to do without ion exchange resin or gac.Because the price of ion exchange resin and gac is generally comparatively expensive, and need a series of support equipment when using, as resins exchange tower, resin regeneration equipment, or filter plant etc.Therefore, existing method of producing refined sugar, no matter slave unit or cost all will increase many than producing white sugar.
Main points of the present invention are when producing refined sugar, needn't pass through all treatment process of usefulness of ion exchange resin or gac or both, its adopts carbonation to replace above-mentioned treatment process in conjunction with the phosphoric acid floating method, just can boiling go out the refined sugar that quality meets national standard fully.
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Fig. 1 adopts this law to produce the technology letter flow process of refined sugar.
With reference to Fig. 1, the production process of refined sugar is: with retro-dissolved syrup through carbonation, heat, be filtered into syrup clearly; After the clear syrup heating, be treated to refinery liquor through the phosphoric acid floating method, boiling becomes refined sugar then.
Above-mentioned retro-dissolved syrup presses the season production period sugarcane, is to use the lime method technical process; The raw sugar Hui Rong that produces forms; If in the sugar refinery phase, then be to form (or multiple earlier sieve back Hui Rong) with raw sugar Hui Rong.Said carbonation method, can wash the back full charge with the used limestone kiln kiln gas process in common carbonatation process sugar refinery, also can utilize the stack gas of boiler, or the carbon dioxide in other source is (in stack gas or the carbon dioxide, concentration of carbon dioxide should not be lower than 8%), full charge after purifying treatment.Said phosphoric acid floating method is that the clear syrup after the above-mentioned peace and quiet processing is fed syrup come-up device, and adds an amount of phosphoric acid and flocculation agent (polyacrylamide), thus the impurity in the floating desaccharification slurry.Syrup in the come-up device, its pH value generally is controlled between the 6.8-7.5.
All the employed equipment of method of usefulness is much simple because the phosphoric acid floating method is than traditional ion exchange resin or active carbon or ion exchange resin and active carbon, the Master Cost that consumes also reduces greatly, therefore, the present invention compares with existing method of producing refined sugar, it is simple to have equipment, easy and simple to handle, material is saved, the advantages such as cost. In addition, because the production of use this law can be without stove drying, therefore, commerieal sugar is sulfur-bearing not, can be suitable for the use of high-grade drink, food processing and medical industry, also more is conducive to the people's health.
The present invention carried out the pilot production of inside property recently in Shitou Sugarcane Chemical Factory, Guangdong Prov., succeedd and obtain significant effect.
Claims (2)
1, a kind of processing method of producing refined sugar, spent ion exchange resin or gac do not carry out the desalination decolouring and handle to it is characterized in that it.
2, a kind of as the said processing method of claim 1, it is characterized in that adopting the phosphoric acid floating method further to handle boiling refined sugar then with after the filtration of retro-dissolved syrup process carbonation.
