Starch air dryer

1. Overview of starch air dryer project:

Starch is a high polymer of glucose. It is maltose when it is hydrolyzed to the disaccharide stage, 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 connecting 24 to 30 glucose residues end-to-end with α-1,4-glycosidic bonds, with α-1,6-glycosidic bonds at the branch. Amylose is blue when it meets iodine, and amylopectin is purple-red when it meets iodine. This is not because starch and iodine have a chemical reaction (reaction) to produce an interaction (interaction), but the central cavity of the starch spiral can accommodate iodine molecules, and through van der Waals forces, the two form a blue-black complex. Experiments have proved that iodine alone cannot make starch blue. In fact, it is iodine molecular ion (I3) that makes starch blue. Starch is a nutrient stored in plants. It is stored in seeds and tubers. The content of starch in all kinds of plants is relatively high.

2. Principle of starch air dryer:

It is a kind of large-scale drying equipment. It adopts the principle of instantaneous drying and uses the rapid movement of heat-carrying air to drive wet materials and suspend the wet materials in the hot air. This strengthens the entire drying process and improves heat and mass transfer. The unbound moisture can be almost completely removed after the air-dried material (for example, the water content of the feed material such as starch is ≤40%, and the finished material can be 13.5%), and the dried material will not deteriorate Phenomenon, the output can be significantly improved compared with the general drying machine, and the user can obtain higher economic benefits in a short period of time.

3. Application range of air dryer:

It is suitable for drying and dehumidifying powdered materials in the 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· S·C benzoic acid, 2.3·acid, polychloroacetic acid, polypropylene, sodium sulfate, sodium metabisulfite and other materials are dried.
