- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in the processing drum construction?
**A**: The processing drum is constructed from corrosion-resistant stainless steel, specifically AISI 304 or 316 grades, ensuring durability and compliance with industrial hygiene standards.

### Q: How does the internal baffle system improve processing efficiency?
**A**: Internal baffles or fins enhance material mixing and processing by creating turbulence within the rotating drum, ensuring uniform exposure to vacuum conditions and improving processing consistency.

### Q: What maintenance is required for the drum's sealing system?
**A**: Regular inspection of the vacuum sealing system is recommended, including checking gaskets and seals for wear, to maintain optimal vacuum performance and prevent processing contamination.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
