Ethyl chitin is obtained by deacetylation of chitin. The chemical name is polyglucosamine (1-4)-2-amino-B-D glucose. Since the French Rouget first obtained ethyl chitin in 1859, this excellent natural polymer has the characteristic of biofunctionality and compatibility, blood compatibility, safety, and microbial degradability, thus it have been widely concerned by all kinds of industrial, especially the fields such as medicine, food, chemical industry, cosmetics, water treatment, metal extraction and recovery, biochemical and biomedical engineering. For patients, the effects of ethyl chitin is reducing blood lipid and blood sugar.
Under specific conditions, ethyl chitin can undergo chemical reactions such as hydrolysis, alkylation, acylation, carboxymethylation, sulfonation, nitration, halogenation, oxidation, reduction, synthesis and complexation.
The drying process requires a circulating air duct. The system with side air outlet basically has no dead ends. However, the requirement of ethyl chitin products is relatively high, thus stainless steel rivets with arc-shaped corners can be used at the corners of the air duct to increase the wind speed.
The whole drying process can be finished in 3 stages. The first stage should set the temperature at 55°C, and the humidity is 45%. A lot of moisture should be removed in this stage.
The temperature in the second stage is 60°C, 30% humidity. A lot of moisture should be removed in this stage.
The temperature in the third stage is 58°C, a small amount of moisture should be removed, and the humidity is 20%.
