Selection of drying equipment
Thread Content
A company has a type of salt, sodium sulfite, with a moisture content of 20%; to reduce this to below 10%, what kind of drying equipment would be suitable?
Scraper discharge centrifuge, or filtration
Spray drying seems to be quite efficient; any manufacturer produces this type of equipment
For large volumes, a fluidized bed can be considered; for small volumes, a bubbling bed can be considered
Poster: I have also been paying attention to sodium sulfite products recently, so here is some information I’ve found: 1. Sodium sulfite is unstable; the heating temperature should not be too high! Drying at 250–300°C yields anhydrous sodium sulfite as the final product ； 2. The poster mentioned that the incoming material has a water content of 20%, and sodium sulfite contains 7 molecules of crystal water; therefore, the material you need to process contains some crystal water ； 3. If the processing volume is large, it is recommended to use a fluidized bed or a rotary kiln; if the volume is small, intermittent drying equipment will suffice. I hope the above is helpful to you! If you still have questions, feel free to raise them so we can discuss them together.
