The impact of excessively high drying temperatures on ammonium sulfate products
Thread Content
I would like to ask the teachers: I read in a book that if the temperature of the heat dryer is too high, it can cause the ammonium sulfate product to clump together. Is this because ammonium sulfate transforms into ammonium bisulfate, or what is the reason? What impact does an excessively high drying temperature have on the ammonium sulfate product?
No impact; it’s just that the moisture level is a bit low. You’re losing money on that, so check the sales metrics.
Sulfate of ammonium decomposes when heated above 250 °C, first forming bisulfate of ammonium. Heating at even higher temperatures leads to its decomposition into ammonia, nitrogen, sulfur dioxide, and water.
