1. Project overview:

   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 a chemical reaction between starch and iodine, and an interaction, but the central cavity of the starch helix can accommodate iodine molecules. 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 various plants is relatively high.


2. Equipment overview:

   The starch special paddle dryer can indirectly heat or cool paste, granular, powder, and slurry materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature combustion. The special wedge-shaped stirring heat transfer blade in the equipment has higher heat transfer efficiency and self-cleaning function of the heat transfer surface.
