Fluidized bed dryer can directly dry liquid materials, with a variety of functions such as rapid drying of particles and powder materials. The hopper for loading materials is conical, which can increase the flow rate of materials and facilitate fluidization. The materials are not easy to form a dead angle in the hopper. The materials absorb heat evenly and dry fast. A sampling device is equipped in the hopper for loading materials, which can sample at any time to test the drying end point of materials and ensure the quality of products.
Boiling dryer has cold air post-treatment process, the dried material can be cut by cold air in time. It can prevent materials from deteriorating due to excessive waste heat and ensure the drying quality of materials. Special materials are used for air thermal filtration to prevent foreign matters in the radiator and impurities in the air from entering the materials and ensure the cleanliness of the materials. A special gas distribution plate is designed in the boiling dryer to make the heat carrying gas flow enter into the dryer in a transverse spiral shape, so that the boiling material flow contacts the heat carrying gas flow separately, and the heat absorption is uniform, and the material drying is fast. The steam consumption is reduced and the energy is saved.
Generally speaking, there are four factors affecting the drying effect, namely drying temperature, drying time and air flow.
The drying temperature of boiling dryer is also an important factor. Heat is the key to opening the water and moisture between polymers. Above a certain temperature, water molecules and polymer chains will greatly reduce the gravity, and water vapor will be blown away by dry air. Therefore, the drying temperature also has an important influence on the drying effect.
Drying time cannot be ignored. The relevant supplier shall specify the time required for the material to dry at the appropriate temperature. Due to the absorption of heat and the diffusion of water molecules to the particle surface, it takes some time in the air around the particle, and the drying time will affect the material to a certain extent.
During the drying process, the hot air transfers the heat to the particles in the drying bin, removes the moisture from the particle surface, and sends the moisture back to the dryer. This time, there must be enough air to heat the resin to the drying temperature and maintain the temperature for a period of time.
