The onion topper is designed to remove the tail and foliage of onions and shallots cleanly and safely with rotating blades, while also removing loose skin and dirt.

The produce is moved using vibrating sieves, causing the onion tails to fall through the sieve, which leads to their removal by the rotating knife.

The enclosed housing and the propeller function of the blade provide closed air circulation in the onion topper. This has a cleaning effect on the onions, makes the machine completely safe to use, and reduces the noise and dust.
