Food-Grade 304 Stainless Steel Rotary Vibrating Screen: Technical Summary
1. Product Overview
The food-grade 304 stainless steel rotary vibrating screen (rotary vibrating sieve) is designed for industries requiring high hygiene standards, such as food processing and pharmaceuticals. It uses SUS304 stainless steel, which complies with food safety regulations, to prevent contamination during material screening. It supports precise particle separation, impurity filtration, and multi-layer grading for powders, liquids, and viscous materials.
2. Key Features
-
Material Safety
- Contact parts are made of 304 stainless steel, offering corrosion resistance and ease of cleaning, meeting GMP and food hygiene standards.
- Seals use food-grade silicone or polyurethane to avoid secondary contamination.
-
Structural Design
- Modular Screen Frames: Enables rapid screen replacement (3–5 minutes) and supports 1–5 layers of sieving, with mesh sizes up to 500目 (28 μm).
- Fully Enclosed Design: Prevents dust leakage and liquid spillage, ensuring a clean workspace.
- Polished Surfaces: Smooth internal and external surfaces meet strict cleanliness requirements.
-
High Efficiency
- Utilizes a three-dimensional vibration mechanism (horizontal, vertical, and tilt motions) to optimize material flow and screening efficiency, achieving a throughput of up to 2 t/h.
3. Applications
4. Selection Guidelines
-
Model Sizing
- Common diameters: 400 mm, 600 mm, 800 mm, 1000 mm (chosen based on production capacity).
- Multi-layer designs enable simultaneous grading of multiple particle sizes.
-
Special Requirements
- Ultrasonic Sieving: Resolves clogging issues with ultra-fine powders (e.g., protein powder).
- Gate-Type/Extended Edge Designs: Suitable for large or agglomerated particles.
5. Maintenance & Operation
- Pre-Use Checks: Verify motor insulation and adjust eccentric block angles.
- Cleaning: Regularly sanitize with alcohol or food-grade detergents to prevent cross-contamination.
- Screen Inspection: Replace worn or damaged screens promptly.
