1. Expansion chamber : made by quality stainless steels plate,.
2. 1st and 2nd passes are both workable.
3. Simple construction and thus low maintenance requirements.
4. Electric control, and valve system for adjustments of steam pressure, even density is achieved.
5. Simple and reliable operation.
6. Safety protection.
7. Drying system including fluidized bed drier is optional
