Dewatering for food waste

 · The lack of a phase change renders the process less energy-intensive and in some instances may improve the end-product quality. Dewatering lowers the moisture content to a level not low enough for shelf stability and thus the dewatered material requires a finish drying treatment or further processing. 21.2.

Mineral Drying

Drying is a critical aspect of mineral processing; throughout the journey from ore to end product, the ability to control moisture content helps to reduce shipping costs, streamline downstream processing, and produce a refined product. While mineral dryers may appear the same as other industrial dryers, they are typically built to withstand more rigorous demands compared to many other industry ...
