Answer 1

SUGAR: sugar, for sugar beets are washed, cut, and through the operation of diffusion is sucrose extracted with hot water at 60-70 degrees Celsius, in countercurrent. Mailing solution contains 15-20% fat soluble substance, out of which 13-15% sucrose and 2-3% nezaharoase substances. Solution of diffusion is treated with lime water, with a content of 1, 5-2, 5% calcium hydroxide, at a temperature of 85-90% ° c. this stage of the technological process of appointment gate DEFECATION. After treatment with lime water, the nezaharoase fling, and it coagulates proteins. Sucrose, reacts with calcium hydroxide to form calcium, zaharati and soluble. In order to prevent sucrose and invert into glucose fructose, along with treatment of acid-neutralizing substances be remembered. The solution resulted in the phase of defecation is filter, for separation of precipitante. Follow the solution is saturated by carbon dioxide breaks down sucrose zaharatul calcium and calcium carbonate. In order to prevent the syrup and decolorarii the processes of fermentation, sulfitation. In this phase the colloidal precipitate in the form of sulphates. By evaporation in vacuum, solution resulting, after sulfitare process acquires a concentration of 60-65% sugar. Crystallization of sugar was obtained by concentrating in boiling apparatus under vacuum at temperatures of 70-90% degrees Celsius. Following centrifugation, the resulting raw sugar and syrup, powdered. Sugar crystals obtained are yellow, with taste and smell, marui characteristic due to the presence of soluble nezaharoase. Removal of these substances, the crystals of zaharse wash with warm water, and soluita obtained are inserted at concentration and recristalizarea. Sugar crystals whitening is achieved by treating with charcoal and boiling. For refined sugar is getting a new spin ...
