Spin flash dryer according to the principles of the role played by the drying process, you can put spin flash dryer equipment is divided into three main parts: the bottom of the fluidized section, ask the drying section, the section-level segment. Different sections of the structure, the role is not the same. (1) fluidized material segment of the population is below section, equipped with a stirrer. It helps break the high viscosity material, wet material with dry hot air full access, resulting in maximum heat transfer coefficient. Material from the screw conveyor into the drier, first bear agitator mechanical crushing, under the action of centrifugal, shear, impact force of the material to be micronized, full contact with the rotating hot air form a fluidized bed is fluidized. After drying fluidizing section, the material is broken into various particle sizes of different dried spherical and irregularly shaped particles flash dryer principle, in the rotating air buoyancy and centrifugal force radially flash dryer parts, undried particles to the wall movement, and because it has a larger segment of the sedimentation rate and falling reflux repeat fluidized drying; smaller particles up into the drying section. (2) drying section is the space above the feeding spiral classifier between the material in the rotating wind farm at this time to continue to dry. Smaller particles continue upward into the classification section; the larger particles in the upward movement of the wall surrounding the whereabouts of the classifier collision dry again, until it reaches the drying quality requirements. Hot air drying section after section of the mass flow of heat exchange, reduction of wind speed, humidity increases flash dryer equipment to ensure stable conditions in the drying section smoothly. Material in order to control the residence time within the dryer, should be asked to adjust the air flow rate according to the air in the dryer stay, so that the particle size, yield and final moisture content of the finished product is controlled, so that the dryer to form a feed rate dry goods and balance between production to meet the requirements. Spin flash dryers little affected by the moisture content of the final product moisture content of feed fluctuations, which is one of the advantages of the dryer. (3) comprises a hierarchical stage classifier is a classifier, including the part above. Classifier is an open hole circle baffle, by changing the diameter and height of the classification section of the hole, i.e., changing the air flow rate leaving the dryer may control the size and number of particles. In this section complete drying of the material to achieve the size requirements were captured with the hot air into the dust. Flash dryer airflow characteristics of a product, as a result of the material by centrifugation, shear, collision, friction is micronized was highly decentralized state and the relative velocity between the gas-solid larger, enhanced heat transfer and mass transfer, so that the production of high strength aircraft . 2, dry gas into the bottom of the dryer, a strong rotating air, on the wall materials have a strong rushing effect, eliminate the sticky wall phenomenon. 3. At the bottom of the dryer temperature zone flash dryer, heat sensitive materials are not in direct contact with hot surfaces, solves the problem of coking discoloration of heat-sensitive materials. 4, due to the gas velocity inside the drying chamber is high, short residence time to achieve efficient, rapid, large-scale production of small devices. 5, built-swirl drying chamber piece, in order to control the material moisture to reach very low levels. 6, the upper part of the drying chamber can control the export of material dispersed particle size and moisture.
