With the classical technology for making sugar from beets, modern manufacturers use disinfectants that are harmful to health - bleach, formalin, hydrogen peroxide, ambisol. But you can also produce absolutely pure sugar without harmful impurities, if you use modern methods of cleaning beet wort.
When exporting sugar to the EU countries, modern requirements are imposed on the product sold, so the manufacturer must obtain pure sugar, which will not contain disinfectants hazardous to health. To ensure that sugar refining is in line with accepted European standards, first, pay attention to refining the diffusion juice of the sugar beet. In addition to sucrose, beet juice contains non-sugar, decomposition products of pectin substances. Use modern methods of physical and chemical purification, in which non-sugar is removed from the sugar beet juice sediment with the help of special reagents.
Use carbon dioxide and calcium hydroxide as reagents, which accelerate the reactions of precipitation, coagulation, hydrolysis, decomposition, ion exchange and adsorption. With the help of these processes, sugar refining becomes as efficient as possible, and the consumption of reagents is reduced to a minimum. Secondly, clean the diffusion juice in pulp traps, and then pour it into special heaters, heat it to a temperature of 85 ° C-90 ° C and then send the already warmed beet juice in a progressive pre-deflation.
Modern technology of sugar refining provides for the introduction of milk at the last stage of refining in a proportion of 0, 2-0, 3% in relation to the weight of the processed beet. Third, to obtain pure sugar, use a pre-deflation process during which the beet juice reaches its normal metastable state, in which the pH fluctuates between 8.5-9.5. Gently introduce into the mixture to be purified a thickened juice suspension, characterized by II saturation. Conduct a cold defecation of the beet juice in a special apparatus for half an hour, after this procedure, warm it up again to 85 ° C-90 ° C and serve it in a defoctor for hot defecation for ten minutes.
Thirdly, for effective sugar cleaning, add milk of lime to the beet juice at the rate of 0.7% by weight of the glass already at the outlet of the defiler. This procedure will help to improve the filtering properties of beet juice and the quality of the saturation performed. Then send the defected juice to the circulation collector, in which it is automatically mixed with saturate, which is recirculated along the external circuit for ten minutes. After thorough cleaning, the beet juice will flow by gravity into the container - pump it from there with a pump to a special pressure collection container.
