This onion sorting line enables continuous operations from onion feeding and grading to final packaging, significantly reducing manual labor while ensuring uniform product specifications and neat appearance, thereby enhancing overall market competitiveness. It primarily employs a grading machine for precise onion classification, followed by an automated onion packing line that packs onions into mesh bags.

The onion sorting packing line features rational design, robust construction, and simple operation, making it suitable for large onion farms, onion processing plants, and similar facilities. Beyond onions, this sorting and packaging line can also handle a wide range of round or near-round root vegetables such as potatoes, garlic, radishes, and beets, offering broad applicability.

Onion Sorting Line Working Principle:

Onion sorting is primarily achieved based on diameter size. The grading machine consists of multiple sets of evenly spaced rollers. During operation, the gaps between the rollers gradually widen. As the onions move forward with the rollers, smaller onions fall into the corresponding receiving troughs at the front section due to the narrower gaps. As the gaps progressively increase, medium and large onions respectively fall into their designated collection channels at the rear end.

Onion Sorting Packing Line Equipment Configuration:

Feeding conveyor belt: Uniformly transports onions to the sorting equipment, reducing manual handling.
Sorting machine: The core equipment of the production line, sorting onions by diameter size.
Sorting platform: Manually removes damaged, moldy, and substandard onions to ensure finished product quality.
Buffer hopper: Temporarily stores graded onions, enabling smoother and continuous packaging.
Automatic weighing and mesh bag packaging machine: Automatically fills graded onions into mesh bags in 1kg, 2kg, 5kg, 10kg, and other specifications, completing sealing.

Onion Sorting And Packing Line Features:

Precise grading with minimal damage: The roller bar sorting method is gentle and stable, preventing onion crushing and enabling extended continuous operation.
High automation for labor savings: Optional automatic packaging line significantly reduce manual weighing and bagging steps, achieving continuous production.

Simple operation and easy maintenance: The control system is intuitive and straightforward. The onion sorting packing line features a robust and durable structure with extended maintenance intervals.
Enhanced product uniformity and market value: Graded onions exhibit consistent sizing, facilitating sales and boosting overall product value.
Customizable solutions: The onion sorting packing line can be flexibly configured to meet customer output requirements, with capacities ranging from 1 ton/hour to over 10 tons/hour.
