The characteristics and scope of the flash dryer
The flash dryer has the advantages of high thermal efficiency, short drying time and good energy saving effect. The paste-like material can be directly dried to form a powdery dry product, saving the pre-treatment before drying, drying and crushing, screening and other processes; due to drying speed, material heating time is short, easy to destroy the dry material components, Is conducive to the drying of heat-sensitive materials; drying process is completely closed, no impurities mixed into the finished product of high quality, good operating environment. At present, the flash dryer has been based on different materials designed a variety of models, and the formation of a series of products, chemical, pharmaceutical, light industry, food, minerals and other industries more and more widely.
Typical dry materials are:
Inorganic: borax, calcium carbonate, hydroxide, copper sulfate, iron oxide, barium carbonate, antimony trioxide, various heavy metal salts, synthetic cryolite, manganese carbonate, magnesium carbonate, sodium sulfite, dibasic calcium phosphate, Iron red, aluminum hydroxide, sodium acetate, white carbon black, bentonite and so on.
Organic acids: lauric acid, benzoic acid, benzoic acid, sodium oxalate, cellulose acetate, melamine, tin triphenyltin acetate, methyl cellulose, bromine, DSD acid, 2,4-D acid, H acid, J Acid and so on.
