Problems solved by technology

In the implementation of the above conditions it was proved that the refining slurry purification of organically synthesized polymeric flocculants does not achieve a sufficiently high efficiency, at the same stage in the removal of ionic and non-ionic non-sugar components of the percolating slurry in the case of their application

example 1

[0029] Example 1. Supply of sweet crumbs to a double-helix percolator with sugar content (CX) - 15.5%, solid matter (CB) - 19.05%, beet purity (ㄐ) - 81.38%, heated and ready for non-anionic flocculation Agent solution—chloropropylene dimethylamine—polyelectrolyte, quantitatively 60 mg / liter slurry and acidic reactant—phosphoric acid, quantitatively 40 mg / liter slurry.

[0030] These solutions were introduced into the body of the apparatus in the water supply zone, which had a pH of 7.8 and a temperature of 72°C. Simultaneously prepare non-organic coagulant solutions - aluminum oxalate, quantitatively 65 mg / l slurry and calcium hydroxide solution - 75 mg / l slurry (0.05% beet content), supply these solutions and heat beet chips in the supply area. The percolation slurry obtained as a result of extraction of beet shavings had a purity (ㄐ) of 86.5%, a non-sugar content of 0.85% in dregs, and a cleaning efficiency of the slurry of 31.8%. Then a non-organic coagulant—titanium sulfa...

example 2

[0032] Example 2, sugar beet crumbs are supplied to the boiling water scalding tank of the colloidal percolation device, which has sugar content (CX)—15.1%, solid matter (CB)—18.4%, beet purity (ㄐ)—81.2%.

[0033] Prepare non-anionic flocculant aqueous solution-polyethylene dimethyl ammonium chloride, quantitatively 40 mg / liter slurry and acidic reactant-phosphoric acid, quantitatively 30 mg / liter slurry. These solutions were introduced into the body of the apparatus at the water supply area, which had a pH of 7.8 and a temperature of 72°C. At the same time, prepare the non-organic coagulant solution—titanium sulfate Ti(SO 4 ) 2+ , Quantitative is 10 mg / L slurry and calcium hydroxide solution-75 mg / L slurry, and these solutions are delivered to the boiling water scalding tank of the device together with the beet crumbs.

[0034] The percolation slurry obtained as a result of extraction of sugar beet shavings had a purity (ㄐ)—86.9%, a non-sugar content in dregs of 0.9%, clean...

example 3

[0036] Example 3, feeding sugar beet crumbs to the double-helix percolation device, it has sugar content (CX) - 15.5%, solid matter (CB) - 18.9%, beet slurry purity (ㄐ) - 82%. Prepare non-anionic flocculant aqueous solution—chloride of polyvinylmethylammonium, quantitatively 40 mg / liter slurry and acidic reactant—phosphoric acid, quantitatively 30 mg / liter slurry. These solutions were introduced into the body of the apparatus in the water supply zone, which had a pH of 7.8 and a temperature of 72°C.

[0037] At the same time, prepare a non-organic coagulant solution—titanium sulfate Ti(SO 4 ) 2+ , Quantitative is 10 mg / L slurry and calcium hydroxide solution-75 mg / L slurry, and these solutions are sent to the middle area of ​​the device, which is the mixture of the third part slurry and beet chips.

[0038] The slurry obtained as a result of extraction of beet chips had a purity (ㄐ) of 88.7%, a sugar content (CX) of 14.6%, and a solid matter (CB) of 16.5%. The non-sugar con...

Abstract

The inventive method consists in forming nonsucrose precipitates during a sucrose extraction process in a diffuser by binding nitrogen-containing and nonnitrogenous high-molecular nonsucroses and colloidal dispersion agents, deposing nonsucrose precipitates on beet cossets and in removing them from a diffusion juice with a beet pulp, aggregating nonsucrose dispersed particles in the diffusion juice neutral-acid medium, flocculating said particles and removing them together with a precipitate by filtering or separating, defecating a filtrate, coagulating and flocculating a defecated juice nonsucroses in an alkaline medium, separating the precipitate, neutralising the purified juice, thickening it and in boiling a fillmass. The method uses in said production process the synergism of the interaction of inorganic coagulants of metal salts solutions and organic flocculants of synthetic polymers, thereby making it possible to substantially improve the purity of sugar-containing solutions and to reduce a production process at a lime/carbon dioxide purification plant.

Description

technical field [0001] This invention is relevant to the sugar industry. Background technique [0002] It is well known that sugar production methods include scalding sugar beet crumbs and extracting it to obtain a seepage slurry, preparing non-organic aluminum dihydroxy sulfate coagulants and non-anionic (cationic) polytetravinyl N benzyl trimethyl chloride Ammonium flocculant, coagulant and flocculant are introduced before scalding sugar beet crumbs with boiling water or during the process of scalding, this is to reduce the content of diffusible colloidal substances and the loss of sugar in the seepage slurry. (Patent No. SU 1377294, issued February 29, 1988). [0003] A disadvantage of the known method is that the cleanliness of the beet pulp is not high, since a mixture of non-organic coagulants and polymeric flocculants is used during the sugar refining process. [0004] As is well known, sugar production methods include crushing or crumbling sugar beets, scalding the...
