How to Dry Chitosan/Dehydrate Chitosan in a Dehydrator
Introduction to chitosan：
Chitosan, also known as chitin, is obtained by deacetylation of chitin, which is widely present in nature, and its chemical name is polyglucosamine (1-4)-2-amino-B-D glucose. Since the French Rouget first obtained chitosan in 1859, the excellent properties of this natural polymer such as biofunctionality and compatibility, blood compatibility, safety, and microbial degradability have attracted wide attention from all walks of life. Significant progress has been made in applied research in many fields such as medicine, food, chemicals, cosmetics, water treatment, metal extraction and recovery, biochemical and biomedical engineering. For patients, the effect of chitosan on lowering blood lipids and blood sugar has been reported.Under certain conditions, chitosan can undergo chemical reactions such as hydrolysis, alkylation, acylation, carboxymethylation, sulfonation, nitration, halogenation, oxidation, reduction, condensation, and complexation, and can generate a variety of different chemical reactions. Performance of chitosan derivatives, thereby expanding the application range of chitosan.
Chitosan drying process：
The drying process requires a circulating air path. Because the side-outlet system basically has no dead corners, but the most demanding of such products is higher. You can use stainless steel riveting such as arc-shaped corners at the corners of the wind road to increase the wind speed. The 3 stages are scheduled to be completed, the first stage is 55°C, the humidity is 45%, and a lot of dehumidification. The second stage is 60℃, humidity is 30%, and a lot of dehumidification. The third stage is 58°C, with a small amount of dehumidification, and the humidity is 20%.
Recommendation of chitosan dryer/drying machine
Commercial 100-3000kg/h large amount of dehydration wide application and easy operation
Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.
Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
