Onion peeling machine

Processing type Peeling
Suitable for Onions

As the market leader in onion peeling machines, the TopNotch distinguishes itself with a revolutionary automatic orientation and coring system. Utilizing vision technology, the machine precisely positions each onion with unparalleled accuracy. The unique coring system selectively removes only the top and tail, preserving the maximum amount of product. Designed for large-scale production, capable of handling up to 12,000 onions per hour, the TopNotch onion peeling machine ensures unparalleled peeling quality.

Coring system

Unique upper and lower vertical coring system increasing yield up to 10%.

With minimal compressed air, the TopNotch removes the onion skins, leaving a perfect final product.


Above the orientation station, a camera captures continuous images. These images are processed by a computer, determining the location of the onion’s top and tail. The orientation station adjusts, rotating the onion until it reaches the correct position. With this precise positioning, the onion peeling machine, equipped with its unique coring system, selectively removes only the actual top and tail. This results in a 10% increase in product yield compared to other systems. Minimal pressure is applied during coring, preserving the onion’s shape, contributing to extended shelf life, and facilitating further processing.


Unlike a continuous flow, the TopNotch onion peeling machine employs a start-stop system, achieving maximum control over the peeling process. Onions progress through various stations, from orientation to peeling. Each step is meticulously executed to ensure an accurately and uniformly peeled end product. This precision is crucial for delivering high-quality onions that meet the strictest hygiene standards.

With its innovative design, the TopNotch onion peeling machine represents industrial precision, maximum yield, and operational convenience. Experience the revolution in onion processing and elevate your production to a higher level.
