A large cultural tourism complex generates substantial daily food waste with complex composition, including leftover meals, oily water, and plastic bags. The existing treatment method suffered from issues such as strong odors, frequent blockages, and high labor costs, necessitating urgent automation upgrades.
Operational Challenges
High Corrosivity: Fermented waste becomes acidic, easily corroding equipment
Prone to Entanglement and Blockage: Long-fiber items like plastic bags easily snag traditional conveying equipment
High Sanitation Requirements: Odor control and easy equipment cleaning are essential
Solution
Implementation of a 304 stainless steel shaftless screw conveyor featuring core technological advantages:
Shaftless Design: Eliminates the central shaft with a ribbon-shaped screw blade, allowing direct passage of plastic bags and debris to completely resolve entanglement issues while boosting conveying efficiency by over 30%
Stainless Steel Construction: Both trough and blades are made of 304 stainless steel, resistant to acid and alkali corrosion. Service life is 2-3 times longer than carbon steel equipment, with a smooth surface for easy cleaning.
Fully Sealed Conveying: Equipped with sealed cover plates to effectively prevent odor leakage and improve the working environment.
Flexible Layout: Supports both horizontal and inclined conveying to adapt to site layouts.
Application Results
Efficiency Improvement: Automated continuous conveying reduces labor costs and ensures stable feed supply to downstream production lines.
Reduced Failure Rate: Anti-entanglement design decreases failure rate by over 70%.
Improved Environment: Sealed conveying minimizes odors; stainless steel facilitates daily cleaning, meeting stringent environmental standards.
Conclusion
With advantages including corrosion resistance, anti-entanglement, and easy cleaning, the stainless steel shaftless screw conveyor provides an efficient and reliable solution for processing complex materials like food waste. It represents an ideal choice for environmental upgrades.
