Working principle and structural characteristics of single cone spiral belt vacuum dryer
Date: 2025-02-21Read: 9
The single cone spiral belt vacuum dryer is an efficient and multifunctional fully enclosed vertical vacuum drying equipment. Its design integrates multiple functions such as mixing, drying, and crushing, and is widely used in industries such as pharmaceuticals, chemicals, pesticides, and food.
The working principle of the single cone spiral belt vacuum dryer is based on the combination of vacuum drying and stirring drying. Its core components include a single conical cylinder, a spiral stirrer, a vacuum system, a heating system, and a cooling system. When working, first add the wet material into the conical container through the feeding port. Subsequently, the spiral stirrer began to rotate, evenly stirring and mixing the materials. The heating cone is equipped with a heating jacket, and the heat source can be hot water, thermal oil, or low-pressure steam to maintain a certain temperature on the inner wall of the cone. Under the action of stirring and heating, the moisture or solvent of the material gradually evaporates and is extracted through a vacuum system to achieve the purpose of drying.
Single cone spiral belt vacuum dryerStructural composition and characteristics:
1. Single cone tank design: The single cone spiral belt vacuum dryer adopts a single cone tank design, with a simple structure and easy operation. The tank body is made of sanitary grade stainless steel, which meets GMP requirements and is suitable for industries such as pharmaceuticals, biology, chemicals, and food.
2. Spiral belt mixer: The spiral belt mixer consists of a mixing spindle and two spiral belts and blades that match the inner wall surface of the cylinder. When rotating, the spiral belt and spiral blades lift the material from bottom to top along the inner wall of the cylinder, forming a three-dimensional motion in multiple directions, enabling the material to achieve uniform mixing and drying in a short period of time.
3. Heating jacket: The heating cone is equipped with a heating jacket, which maintains a certain temperature on the inner wall of the cone by introducing different types of heat media, meeting the user's requirements for process temperature control.
4. Vacuum system: The vacuum system consists of a vacuum pump and vacuum pipelines, which dry materials by extracting moisture from the tank. Meanwhile, the vacuum system can also prevent oxidation of materials during the drying process, ensuring the quality of the materials.
5. Cooling system: The cooling system is used to cool the equipment after drying, preventing the material from deteriorating due to high temperature. Cooling systems typically achieve rapid cooling of equipment by introducing cooling media such as cold water or cooling oil.
