Starch air dryer

Project overview of starch air dryer

Starch is a high polymer of glucose, which is hydrolyzed to disaccharide stage to maltose, and monosaccharide (glucose) is obtained after complete hydrolysis. There are two types of starch, amylose and amylopectin. The former is an unbranched helical structure; the latter is formed by 24-30 glucose residues connected end-to-end by α-1,4-glycosidic bonds, and α-1,6-glycosidic bonds at the branched chain. Amylose is blue in the presence of iodine, and amylopectin is purple in the presence of iodine. This is not because the starch and iodine undergo a chemical reaction (reaction), resulting in an interaction (interaction), but the central hole of the starch helix can just accommodate the iodine molecule, and through the van der Waals force, the two form a blue-black complex. Experiments have shown that iodine molecules alone cannot make starch blue, and it is iodine molecular ions (I3) that actually make starch blue. Starch is a nutrient stored in plants, stored in seeds and tubers, and starch content in all kinds of plants is high.

The principle of starch air dryer

It is a large-scale drying equipment. It adopts the principle of instant drying, and uses the rapid movement of the heat-carrying air to drive the wet material, so that the wet material is suspended in the hot air, which strengthens the entire drying process and improves heat and mass transfer. The unbound moisture can be almost completely removed from the air-dried materials (for example, the feed water content of starch and other materials is less than or equal to 40%, and the output of finished products can be 13.5%), and the dried materials will not deteriorate. phenomenon, the output can be significantly improved compared with the general drying machine, and users can achieve higher economic benefits in a short period of time.

Application range of air dryer

It is suitable for drying and dehumidification of powdery materials in pharmaceutical, chemical, food, building materials, plastics and other industries, such as starch, fish meal, salt, distiller's grains, feed, gluten, plastic resin, mineral powder, coal powder, sugar chloric acid, A· Drying of various materials such as S·C benzene formic acid, 2·3· acid, polychloroacetic acid polypropylene, sodium sulfate, sodium metabisulfite, etc.
