[0002] Bio-based succinic acid is a common natural organic acid, a chemical substance produced by microorganisms through fermentation. Pure succinic acid is a colorless crystal, sour, flammable, soluble in water and ethanol, and decomposes under high temperature. At the same time, succinic acid is an important basic raw material. Its application fields include medicine, spices, food preservation, condiments, food additives and surfactant industries. In addition, it is also used to produce degradable plastics, such as PBS, PBST, PBSA, clothing biofibers, polyurethanes, polyethers and other polyester products;

[0003] The process of preparing bio-based succinic acid by bio-fermentation is strain selection, fermentation and separation and purification. Common methods of separation and purification include ion exchange, extraction and crystallization. Among them, crystallization is more commonly used and can obtain succinic acid with higher purity. The succinic acid after separation and purification is wet material, which needs to be dehumidified and dried. Since the preparation of bio-based succinic acid by bio-fermentation started late, the bio-based succinic acid market has only developed rapidly since 2010. Therefore, there is a lack of drying equipment for the processing of bio-based succinic acid on the market. The drying bed of the traditional dehumidification dryer is horizontally designed, and the material is pushed forward by vibration, and the discharge speed is slow.

[0004] Therefore, it is particularly important to design a drying treatment device to meet market demand. Utility Model Content
