Abstract
The sucrose juice decolorizing process includes the following steps: low temperature phosphoric acid floating treatment of mixed juice in the purity of 78.19 AP and through preheating to 50 deg.c, adding phosphoric acid mixture, neutralizing with lime milk, inflating, adding flocculant and separating out neutral slime, to obtain clear juice of purity raised to 80.66 AP and color value lowered to 92.66 st deg; pre-decolorizing the clear juice heated to 75 deg.c with diatomite in 1.0 wt% of sucrose for 60 min to lower the color number to 75.23 st deg; and decolorizing the clear juice with active carbon in 1.0 wt% of sucrose for 30 min to further lower the color number to 30.70 st deg. The process has the advantages of no production of alkali slime, short technological process, high purity of obtained sucrose juice and greatly lowered color number.
Description
Technical field
The present invention is a kind of decoloring method skill of making sucrose mix juice.
Technical background
Carbonatation process is adopted in China's cane sugar manufacture industry, or sulfurous method.The sugar product quality that the former produces is better, but complex process, cost is higher, and the filter mud generation is big, can not be used as fertilizer, but need store up cement baking more than 5 years, need build the big area stockyard, stores up to produce secondary pollution in the process.Sulfurous method production process is simpler, invests lessly, and filter mud can be used as farmland fertilizer, but product colour, turbidity, ash, sulphur content height, brightness reversion easily, keeping quality is poor, does not meet market demand day by day.The low-temp phosphorus floatation method of arising at the historic moment one carbonatation process clarification process, but there is following subject matter in this technology: the direct cement baking of alkaline mud, cost is higher, is difficult to be accepted by manufacture of cement producer; Cause the sugar product cost to improve; Technology is long.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of decoloring method of making sucrose mix juice is provided.
Technical scheme of the present invention is: a kind of decoloring method of making sucrose mix juice, and diatomite uses behind 800 ℃ of roasting 6h, and its add-on is the 1-3wt.% of sucrose part, and pre-bleaching temperature is 50-75 ℃, and pre-bleaching time is 30-60min; In the activated carbon decolorizing process, the gac add-on is the 0.6-1.5wt.% of sucrose part, and bleaching temperature is 50-85 ℃, and bleaching time is 15-90min.
The present invention has the following advantages: avoided alkaline mud, shortened technical process.Improve juice purity, reduce its colour.
Embodiment
Embodiment: the decoloring method of making sucrose mix juice, purity is the mixing juice of 78.19AP, be preheated to 50 ℃, add the phosphoric acid mixture, neutralize with milk of lime, charge into fine uniform bubble, and the adding flocculation agent, carrying out the low-temp phosphorus floatation method and handle, the neutral filter mud after the separation can directly be used as fertilizer or further extract high value added product, purity of clear juice is brought up to 80.66AP, colour is reduced to 92.66 ° of st, will float clear juice and be heated to 75 ℃, adds the diatomite with respect to sucrose part 1.0wt.%, pre-decolouring 60min, the syrup colour is reduced to 75.23 ° of st, adds the craboraffin with respect to sucrose part 1.0wt.% then, continues decolouring 30min, the syrup colour is reduced to 30.70 ° of st, and this process does not produce alkaline mud.
Claims (1)
1, a kind of decoloring method of making sucrose mix juice, purity is the mixing juice of 78.19AP, be preheated to 50 ℃, add the phosphoric acid mixture, neutralize with milk of lime, charge into fine uniform bubble, and the adding flocculation agent, carrying out the low-temp phosphorus floatation method and handle, the neutral filter mud after the separation can directly be used as fertilizer or further extract high value added product, it is characterized in that: purity of clear juice is brought up to 80.66AP, colour is reduced to 92.66 ° of st, will float clear juice and be heated to 75 ℃, adds the diatomite with respect to sucrose part 1.0wt.%, pre-decolouring 60min, the syrup colour is reduced to 75.23 ° of st, adds the craboraffin with respect to sucrose part 1.0wt.% then, continues decolouring 30min, the syrup colour is reduced to 30.70 ° of st, and this process does not produce alkaline mud.
