Product Advantages


Unlike older models—which feed onions downward into a chamber for batch processing—this new model features horizontal feeding. Onions are peeled directly while being conveyed; this high-speed process minimizes collisions and bruising between onions. Furthermore, because each onion bulb is peeled individually under pressure, the peeling efficiency is higher.

1. High peeling rate (≥99%)
2. Dry peeling process; requires no water and causes no environmental pollution
3. No damage to the produce
4. Peeling process is not restricted by onion size; mixed sizes can be peeled effectively in a single run
5. Compact structure with a small footprint; constructed entirely of stainless steel
6. Stable performance; practical, safe, easy to maintain, and simple to operate

Note: For optimal results and higher output, trim the root and stem ends of the onions before peeling.
