Industry information
Single layer vibrating fluidized bed dryer
Fluidized bed dryer is a simple model that can be divided into two operating methods: continuous and intermittent. Continuous operation has a wide distribution of residence time, so it is often applied to products that are relatively easy to dry or products with less strict requirements for drying indicators. Intermittent operation can be used for drying materials with high moisture content. For some materials with uneven particle size and certain viscosity, low bed operation with agitators installed in the bed layer is often used.
The equipment is easy to operate, easy to maintain, has a stable bed temperature, good drying effect, but has a long operating cycle.
This machine is suitable for drying materials such as ammonium sulfate, ammonium chloride, anhydrous sodium sulfite, polytetrafluoroethylene, calcium gluconate, alkaline Qinglian dye, catalyst particles, casein, coconut, and salt.
Multi layer vibrating fluidized bed dryer
The multi-layer vibrating fluidized bed dryer requires a shorter drying time than a single-layer fluidized bed due to the uniform distribution of residence time. It can improve the uniformity of moisture content in dried products and make it easy to control the drying quality of the products. However, due to the increase in the number of layers, the multi-layer fluidized bed dryer needs to ensure the formation of a stable fluidized state between the layers, which increases the annual complexity of the equipment structure. For materials that remove bound moisture, using a multi-layer fluidized bed is appropriate.
The multi-layer fluidized bed dryer is suitable for drying powdered materials such as polyester chips, sodium salicylate, aminopyridine, oxytetracycline, tetracycline, tablet starch particles, sugar powder, feed, plastics, grains, etc.
