Flash dryer is one of the rapidly developing and widely used models, also known as cyclone dryer or rotary rapid dryer in China. The flash dryer organically combines fluidization, swirling flow, jetting, crushing, and classification technologies. It is an optimized combination of fluidization technology, swirling flow technology, jetting technology, and convective heat transfer technology. The equipment has a high technical content and is suitable for drying paste, granular, filter cake, and mud like materials.
Flash dryer has the advantages of high thermal efficiency, short drying time, and good energy-saving effect. The paste like materials can be directly dried to produce powdered dry products, saving pre-treatment before drying, crushing, screening and other processes after drying; Due to the fast drying speed and short heating time of the material, it is not easy to damage the components of the dried material, which is particularly beneficial for drying thermosensitive materials; The drying process is fully enclosed, with no impurities mixed in, resulting in high product quality and a good operating environment. At present, flash drying machines have been designed with various models based on different materials and have formed a series of products, which are increasingly widely used in industries such as chemical, pharmaceutical, light industry, food, and minerals.
