The Square Gyratory Screen, with its artificial sieving principles and three-dimensional compound motion technology, addresses the pain points of low efficiency, frequent screen blockage, and difficulty meeting hygiene standards in food processing, making it the preferred equipment for food companies. Coreal Machinery has compiled some information for your reference.
1.Working Principle
The Square Gyratory Screen's core innovation lies in its ability to mimic the three-dimensional motion of manual screening. Through the coordinated action of an eccentric block drive and flexible connecting rods, the screen box generates a compound horizontal, vertical, and tilted motion, creating a unique "spiral diffusion + jump stratification" path for material on the screen surface. This motion mode offers three major advantages:
- Improved screening accuracy: Material-screen contact time is extended, achieving a screening accuracy of 99.2%-99.6% for fine powders larger than 200 mesh.
- Enhanced anti-clogging capability: Low-frequency oscillation reduces high-speed material impact, and combined with a bouncing ball cleaning system, the clogging rate is reduced from 27% on conventional equipment to 0.8%.
- Extended screen life: Flexible screening reduces screen wear, resulting in a service life of up to 600 hours.
2.Device Principle
Bionic motion trajectory design
- More uniform material stratification: Fine particles quickly pass through the screen through a "throw-and-slide" cycle, while critical particles (close to the screen size) find a window for passing through during continuous tumbling.
- More complete screen contact: The square screen box design extends material travel and increases contact probability.
- Significant anti-clogging effect: Equipped with food-grade silicone bouncing balls and an ultrasonic assisted cleaning system, the clogging rate can be controlled below 0.8%.
Food-grade structural design
Meeting the hygienic requirements of the food industry, the Square Gyratory Screen utilizes a fully enclosed stainless steel structure:
- The material contact parts are made of SUS304/316L stainless steel, surface roughness Ra ≤ 0.8μm.
- Quick-release screen frame design, sealing ring made of food-grade silicone.
- No-dead-angle welding process, meets food contact material standards.
- The dust collection system controls the dust concentration in the workshop to 1.3mg/m³.
3.Technical Advantages
A Double Breakthrough in Efficiency and Precision
The Square Gyratory Screen achieves a leap in performance through three innovative technologies:
- Multi-dimensional Motion Optimization: The eccentric block angle and speed are precisely matched to material characteristics.
- Modular Screen System: The quick-release snap-on design enables screen changes in 3 minutes, supporting a full range of grading needs from 20 to 400 mesh.
- Intelligent Diagnostic Function: Equipped with a vibration sensor and current monitoring module, it provides early warning of abnormal conditions such as bearing temperature rise (>70°C) and screen damage, reducing downtime.
Comprehensive Hygiene and Safety Guarantee
- Surface Treatment: Electrolytically polished interior and exterior surfaces eliminate dead corners for trapped material.
- Cleaning System: Supports CIP Online cleaning, spray balls cover all contact surfaces.
- Material Certification: Key components are certified for food equipment, and silicone parts meet standards.
The Square Gyratory Screen, through its deep integration of biomimetic design, intelligent control, and food-grade safety standards, is reshaping screening standards in the food processing industry. Choosing the right screening solution is not just about upgrading equipment, but also about revolutionizing production methods-this is the transformative power that the Square Gyratory Screen brings to the food industry.
