Embodiment 1

[0038] Step 1, dissolving dimethyl diallyl ammonium chloride homopolymer in water into a solution with a concentration of 10%, and taking 8 kg in a storage tank;

[0039] Step 2, take 30 kilograms of 300 mesh diatomite and 10 kilograms of 300 mesh perlite powder in a mixer, and stir continuously at a speed of 100 rpm. The allyl ammonium chloride solution is slowly added to the powder, and after the polydimethyldiallyl ammonium chloride solution is added, continue to stir for 15 minutes;

[0040] Step 3, then 150 kilograms of polyaluminum chloride (basicity is 85%, Al 2 o 3 Content is 30%) join in the mixer;

[0041] Step 4, at last 5 kilograms of chitosan with a deacetylation degree of 85% are added in the mixer, then continue to stir and stop after 30 minutes;

[0042]Step 5, take out the mixture from the mixer, put it into a bag and pack it to obtain the compound sugar clarifying agent-1 of the present invention.

[0043] The weight percent content of each component is i...

Embodiment 2

[0053] Step 1, get 7.5 kilograms of concentration and be that the copolymer of 10% dimethyl diallyl ammonium chloride and acrylamide and 7.5 kilograms contain the aqueous solution of 10% chitosan quaternary ammonium salt in storage tank and mix to become organic Polymer material mixture;

[0054] Step 2, get 30 kilograms of 300 mesh diatomite, 15 kilograms of 300 mesh perlite powder and 21 kilograms of 300 mesh clay in a mixer, and keep stirring under the condition of 100 rpm at a rotating speed; Slowly add the molecular mixture into the mixer in step 2 of the powder, and continue stirring for 15 minutes;

[0055] Step 3, then 75 kilograms of polyaluminum chloride (basicity is 85%, Al 2 o 3 content is 30%) into the mixer;

[0056] Step 4, finally adding 5 kilograms of chitosan with a degree of deacetylation of 90% into the mixer and continuing to stir after 30 minutes;

[0057] Step 5, take out the mixture from the mixer, put it into a bag and pack it to obtain the compoun...

Embodiment 3

[0072] Step 1, dissolving dimethyl diallyl ammonium chloride homopolymer in water into a solution with a concentration of 10%, and taking 10 kg in a storage tank;

[0073] Step 2, take 15 kilograms of 400 mesh diatomite in a mixer, slowly add 10 kilograms of 10% polydimethyldiallylammonium chloride solution to the powder at a speed of 100 rpm, After adding the polydimethyldiallyl ammonium chloride solution, continue to stir for 15 minutes;

[0074] Step 3, then 165 kilograms of polyaluminum chloride (basicity is 85%, Al 2 o 3 Content is 30%) join in the mixer;

[0075] Step 4, at last 15 kilograms of chitosan with a deacetylation degree of 85% are added in the mixer, then continue to stir and stop after 30 minutes;

[0076] Step 5, take out the mixture from the mixer, pack it into a bag to obtain the compound sugar clarifying agent-3 of the present invention.

[0077] The weight percent content of each component is in this example:

[0078] Polyaluminum Chloride 82.5%,

Abstract

This invention relates to a composite clarification agent used in sugar production. The composite clarification agent is composed of: polymerized AlCl3, organic polymeric materials (including chitosan, chitosan quaternary ammonium salt and dimethyl diallyl ammonium chloride), and ultra-fine powder (including perlitic powder, diatomite and clay) at a ratio of (45-90) :( 1-10) :( 5-50). The composite clarification agent has high electrical neutralization and bridge linkage performances, and has such advantages as low cost, rapid solid-liquid separation and no toxicity. The composite clarification agent is suitable for clarifying mixed juice, filtrate and syrupy in sugar production. The method has such advantages as abundant raw materials, simple process and easy operation.

Description

technical field [0001] The invention relates to the technical field of clarifiers for sugar juice clarification in sugarcane sugar factories. Background technique [0002] At present, in my country's sugarcane sulfite sugar factories, due to the low cleaning and decolorization rate of sugar juice, the color value and ash content of white sugar and SO 2 The high content makes it difficult to produce high-quality white granulated sugar. In order to improve the cleaning and decolorizing effect of sugar juice, sugar factories usually add clarifying and decolorizing agents in the cleaning process of sugar juice. Therefore, the clarifying and decolorizing agent is one of the indispensable chemical auxiliary agents in the sugar clarification process, and its use effect directly affects product quality and cost. The successful development of a high-efficiency clarifying and decolorizing agent will bring a new reform to the sugar-making process and raise the product quality to a ne...
