High-Efficiency, Precise, and Heavy-Duty—Engineered for Modern Poultry Farms and Egg Processors. Welcome to the next level of egg processing with the Automatic Egg Grading Machine. Combining high-precision mechanical engineering with intelligent transmission technology, this equipment delivers seamless egg alignment, smooth conveying, precise weighing, and multi-grade sorting.
High Component Standardization:Key driving and grading components utilize high-precision molded plastic parts, high-strength fiberglass components, and customized aluminum alloy profiles. This guarantees excellent parts interchangeability and long-term running stability.
Gentle, Low-Damage Transfer:Integrating a knife-type conversion conveying mechanism with the classic mechanical lever weighing principle, the machine delivers exceptionally stable transmission and quick, simple grading adjustments.
Variable Differential Acceleration:Our innovative differential mechanism dynamically adjusts the linear speed of egg delivery without affecting total output per unit time. This creates a "gentle and slow loading, fast and efficient transfer" rhythm, drastically reducing egg breakage.
Precise Trajectory Tracking:Utilizing a precise cam-curve structure and a specialized dual-directional chain drive, every single egg follows a pre-calculated running path, passing through the weighing scales efficiently and sequentially.
High Throughput & Near-Zero Breakage:With a top processing capacity of up to 5,400 eggs per hour, the machine supports 24/7 continuous operation. The combination of automatic rubber roller alignment and differential acceleration completely eliminates collision squeeze, driving the overall breakage rate down to an industry low.
Micro-Gram Sorting Precision:Equipped with an industrial-grade lever weighing system supporting both static and dynamic calibrations, the machine achieves a remarkable sorting accuracy of ±0.2g. It supports 5 standard weight grades, where heavy eggs are prioritized for discharge near the conveyor box, while remaining grades exit sequentially.
