Working Principle
Onion Root Cutting Machine adopts photoelectric induction and mechanical positioning cutting principle. During operation, onions are evenly and stably conveyed through a customized stainless steel conveying chain. When the sensor detects incoming onions, the system automatically identifies the center position and size of each onion.
After intelligent positioning, high-speed precise rotary cutters simultaneously trim the dry stem top and fibrous root bottom of the onion. The whole cutting process is completed in one continuous cycle.
Waste onion roots and stems are automatically discharged through the waste outlet, while the finished onions are sent to the next processing procedure. The whole process realizes unmanned automatic operation, effectively avoiding errors caused by manual operation.
Features of Onion Root Cutting Machine
This machine owns multiple practical and industry-leading features. Firstly, it supports automatic size adaptation without manual sorting in advance. It is suitable for onion diameters ranging from 30mm to 120mm, covering small, medium and large common commercial onion specifications.
Secondly, it features adjustable cutting depth and position, allowing factories to flexibly adjust trimming standards according to different product requirements.
Thirdly, the whole machine is made of food-grade 304 stainless steel, which is rust-proof, corrosion-resistant, easy to clean and fully compliant with food hygiene production standards. In addition, the equipment runs stably with low noise and failure rate, adapting to long-time continuous industrial production.

Outstanding Advantages
Compared with traditional manual cutting and old semi-automatic equipment, this Onion Root Cutting Machine has prominent competitive advantages. In terms of production efficiency, the hourly processing capacity can reach 800 to 1200 kilograms, which can replace 6 to 8 skilled workers, greatly saving labor costs and solving the problem of difficult recruitment in peak seasons.
In terms of processing quality, mechanical intelligent positioning ensures consistent cutting effect, neat incision and low onion damage rate, effectively improving product qualification rate and commercial appearance.
The equipment has strong universality and low operating cost. It is compatible with almost all common fresh onion varieties with no limit on onion skin tightness or maturity. Its simple operation design requires only one worker for feeding and routine inspection, greatly reducing operational difficulty and training cost.
