Closed cycle spray dryer 

Product features: This equipment operates in a closed environment and needs to be dried in an inert gas atmosphere, usually filled with nitrogen gas. Mainly to prevent oxidation or the presence of flammable and explosive solvents in the slurry during the drying process. Avoid contact with air by filling with inert gases such as nitrogen. The products produced by this equipment have good consistency and flowability, making them more suitable for powders such as ceramics and hard alloys. The drying medium inside this equipment is usually nitrogen, and the internal operation is generally maintained at a positive pressure, maintaining a certain positive pressure value. If the internal pressure drops, the nitrogen input can be automatically controlled by a pressure transmitter to ensure system pressure balance. The average particle size of 50-150 can be obtained by pressure spray μ The average particle size of 10-100 can be obtained by centrifugal spray μ The powder of m is observed to be…
