Abstract
The invention relates to the field of sugar production, in particular to a sugar production method of ultra-low sulfur white granulated sugar. The sugar production method comprises the following steps: pressing sugarcane to obtain sugarcane juice; adding sodium hydroxide to the sugarcane juice to regulate pH of the sugarcane juice to 5-6; heating the sugarcane juice to 60-65 DEG C; performing flocculation decolorization to obtain clarified liquid; performing membrane separation on the clarified liquid to remove impurities in the clarified liquid and to obtain purified liquid; using acid for regulating the purified liquid to be neutral; performing electrodialysis on the purified liquid for removing salt formed by acid and alkali; then concentrating to obtain concentrated liquid; performing strong alkaline anion exchange on the concentrated liquid to remove pigments and ash; performing weak acid cation exchange for desalination; finally, evaporating and concentrating the obtained sugar liquid, combining and crystallizing to obtain the white granulated sugar. The sugar production method of ultra-low sulfur white granulated sugar provided by the invention is simple to operate, needs no sulfur during decolorization, and reduces sulfur component in the product.
Description
Technical field
The present invention relates to sugared production field is and in particular to the Closed Circulation in Sugar Production method of super-low sulfur white sugar.
Background technology
General cane sugar factory is divided into carbonatation process and sulfurous method, and two methods are required for adding to some extent sulfur dioxide
Decoloured, this process is referred to as stove drying.Stove drying is carried out at twice, and the clear juice stove drying before evaporation is to reduce colour and suppressing high
The stylish pigment of temperature evaporation generates, and the syrup stove drying after evaporation is conducive to reducing the colour boiling sugared clean plasm further, produces symbol
Close the finished product white sugar of colour index.
Stove drying has the pros and cons effect to product quality, first, stove drying can reduce commerieal sugar colour；Second, sulfur
The smoked so2 content (abbreviation sulfur content) that increased commerieal sugar.How to solve this paradox of stove drying, be allowed to both reduce finished product
Fried sugar value does not increase the sulfur content of commerieal sugar again, be Closed Circulation in Sugar Production for many years faced by very stubborn problem.
Content of the invention
The present invention provides a kind of Closed Circulation in Sugar Production method of super-low sulfur white sugar.
The technical solution adopted in the present invention is:
The Closed Circulation in Sugar Production method of super-low sulfur white sugar, including procedure below:
Caulis Sacchari sinensis are squeezed, and obtain Caulis Sacchari sinensis juice, and the ph that Caulis Sacchari sinensis juice adds sodium hydroxide regulation Caulis Sacchari sinensis juice is 5～6, Caulis Sacchari sinensis juice
It is heated to 60～65 DEG C, carry out flocculation decoloration, obtain clear liquor；
Clear liquor carries out the impurity that membrance separation removes in clear liquor, obtains pure liquid, and the acid of pure liquid adjusts neutral；
Pure liquid carries out electrodialysis, and the salinity that soda acid is formed is sloughed, and is then concentrated, and obtains concentrated solution；
Concentrated solution carries out strong alkalinity anion exchange and removes depigmentation and ash, then carries out Subacidity cation exchange desalination；
The sugar liquid evaporation and concentration finally obtaining, combination crystallization obtains white sugar.
The Closed Circulation in Sugar Production method of the super-low sulfur white sugar that the present invention provides, simple to operate, do not need sulfur in decolorization, fall
Sulfur composition in low product.
Specific embodiment
The present invention is further illustrated with reference to embodiments, but the present invention is not limited only to these embodiments, not
On the premise of departing from present inventive concept, any improvement made is within the scope of the present invention.
The Closed Circulation in Sugar Production method of super-low sulfur white sugar, including procedure below:
Caulis Sacchari sinensis are squeezed, and obtain Caulis Sacchari sinensis juice, and the ph that Caulis Sacchari sinensis juice adds sodium hydroxide regulation Caulis Sacchari sinensis juice is 5～6, Caulis Sacchari sinensis juice
It is heated to 60～65 DEG C, carry out flocculation decoloration, obtain clear liquor；
Clear liquor carries out the impurity that membrance separation removes in clear liquor, obtains pure liquid, and the acid of pure liquid adjusts neutral；
Pure liquid carries out electrodialysis, and the salinity that soda acid is formed is sloughed, and is then concentrated, and obtains concentrated solution；
Concentrated solution carries out strong alkalinity anion exchange and removes depigmentation and ash, then carries out Subacidity cation exchange desalination；
The sugar liquid evaporation and concentration finally obtaining, combination crystallization obtains white sugar.
