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%.
