Sugar industry requires the use of sugar juice extraction polyacrylamide flocculation effect is achieved. We use food grade polyacrylamide into sugar production process.
  In beet or cane sugar factory juice clarification manipulation polyacrylamide, joined PAM sap will agglutination occurred. PAM is used in sugar mills where there sugar extraction, sugar sludge dewatering, sewage treatment and other processes. Such as anionic polyacrylamide can be extracted with sugar. Production and life, PAM flocculants are widely applied to food waste water, such as ethanol plants, wineries, sugar mills, meat processing plants. Normal life, some things have flocculant figure.
  Use features
Sugar factory in juice clarification by using the principles and characteristics of polyacrylamide flocculant PAM has a great relationship with the following:
(1) Flocculation, polyacrylamide allow suspended material by charge neutralization, bridging adsorption, since flocculation.
(2) Adhesion, through mechanical, physical, chemical effect, since adhesiveness.
(3) Drop resistance, PAM can effectively reduce the fluid friction, the water will be able to join the micro-polyacrylamide 50-80% reduction in resistance.
(4) Thickening, polyacrylamide thickening effect at both neutral and acid conditions, when the PH value of 10 or more easily hydrolyzed PAM. When a semi-mesh structure, thickening more obvious.

Polyacrylamide in sugar mills, it may be used in industrial-grade, it could be food grade. Therefore, the best use of different models of different processes, ionic polyacrylamide.

Polyacrylamide in the sugar industry, the use of the residual monomer content is a measure of polyacrylamide whether it is suitable for the food industry, an important parameter. Polyacrylamide polymer is non-toxic in the international arena has been widely used for water clean, the food industry and the sugar industry. However, in industrial polyacrylamide, will inevitably have a small amount of residual unpolymerized acrylamide monomers, which have some toxicity. Therefore, the product must be strictly controlled in polyacrylamide residual monomer content. Polyacrylamide international regulations for drinking water and food industries in the residual monomer content of not more than 0.05%. This value is well-known foreign products less than 0.03%.

  Anionic polyacrylamide use effect it has a great degree of influence, but its value is subject to appropriate type and nature of the material being processed may be, will have different optimal values under different circumstances. Based on our years of research and dozens of polyacrylamide sample comparison test and analysis of the sugar industry anionic polyacrylamide used by 22 to 28 per cent fit, and adaptability, can be used for different materials (cane juice, syrup, sugar and red sugar syrup dissolved back) and different processes (sulfite method, carbonation and phosphorus float). The degree of foreign production of sugar anion polyacrylamide majority in this range. Bennett noted that if the high ionic strength of the treated material (including inorganic more), the degree of anionic polyacrylamide used is suitably high, and vice versa should be low. Also, according to Clark's report, 20 percent of Australia's sugar commonly used anionic polyacrylamide degrees, while Florida's sugar commonly higher value. Cress and other studies have found that the flocculant in the juice and the precipitate was removed after the residual amount of polyacrylamide and anionic polyacrylamide original degree related. In conventional water treatment, when no carboxyl group commonly used polyacrylamide.

  Some natural organic polymers such as polysaccharides containing carboxyl more and more starch-containing phosphate groups have flocculation performance. The introduction of chemically reactive groups in the macromolecule can improve this performance, as will a natural polysaccharide etherification reaction introducing a carboxyl group, an amide group after the other active groups, better flocculation properties, can accelerate the sedimentation juice. The natural polymeric substance such as starch, cellulose, chitosan graft-copolymerized with acrylamide, the polymer has good flocculation performance, or a combination of some special properties. Domestic development of some products, the trial had several sugar mills, have better results. Currently the most widely used at home and abroad sugar flocculants, synthetic polyacrylamide products, their development increased rapidly, widespread use in a variety of processes in the sugar industry.

  Polyacrylamide modern production of a variety of different anions of the product, the user can later be used in accordance with the needs and practical test by the choice of appropriate varieties, do not need to re-hydrolyze dissolved. However, because of habit, some people still flocculant dissolution process is called hydrolysis. It should be noted that the meaning of the hydrolysis is hydrolysis, is a chemical reaction, hydrolyzed polyacrylamide are ammonia release; just the physical effect to be dissolved, without chemical reaction. The different nature of the two should not be confused. There are still some sugar technicians do not understand this, even the concept of an error by the previous operation.
