Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a dryer for preparing ferrous sulfate particles. Background Technology

[0002] Ferrous sulfate is an inorganic compound with the chemical formula FeSO4. It appears as a white, odorless powder. Ferrous sulfate granules require drying during preparation, typically achieved through a dryer. Existing dryers generally include a drying chamber with a drying plate inside. The ferrous sulfate to be dried is spread on the drying plate, and then hot air is introduced into the drying chamber. The flowing hot air carries away the moisture from the ferrous sulfate. Although existing drying equipment can meet the requirements, the small contact area between the ferrous sulfate and the hot air flow due to its flat distribution on the drying plate results in slow drying efficiency, thus affecting the production efficiency of ferrous sulfate granules. Utility Model Content
