After the raw materials are baked, the original moisture of the raw materials in the barrel is taken away to achieve the purpose of removing moisture contained in the raw materials.
Likewise, what are the methods of drying? Other methods
- Convection drying.
- Bed dryers.
- Drum drying.
- Freeze Drying.
- Microwave-vacuum drying.
- Shelf dryers.
- Spray drying.
- Infrared radiation drying.
In this regard, what is drying used for?
