TPS PRO Polisher Vegetable Tong Engineering


Newtec Potato Optical Sorting

Whether you require vegetable grading, cleaning, washing or processing equipment, Tong has over 90 years of experience in designing & manufacturing bespoke solutions. We are particularly renowned for our potato grading equipment. Take a look at our full product range.

Danish machinery manufacturers; Newtec, supply simultaneous and advanced optical sorting machines which sort potatoes by quality, size and shape in a single-stage process. Tong Engineering is proud to work alongside Newtec on advanced optical sorting projects in the UK and worldwide and has vast experience in integrating the particularly popular Newtec Celox potato optical sorting machine within complete Tong turnkey optical sorting solutions, resulting in a high-quality optical grading facility for maximum handling efficiency.

The advanced technology found in the Newtec potato optical sorting machine, ensures rapid sorting of washed potatoes, removing the need for pre-grading whilst decreasing labour, time and costs. Each potato is individually checked as it passes through the camera section of the optical sorter. The advanced vision capabilities of the Newtec Celox optical sorter utilise three cameras that capture precise data on each potato, including size, shape and overall quality. The unique vibrating rollers ensure that the potatoes are gently rolled and propelled forward to ensure every angle is captured at the camera phase, providing the most detailed and accurate data available.


The process of sorting potatoes using the Newtec Celox is designed to save time, money and labour. Maximum efficiency is in mind throughout this machine, which grades potatoes into different categories based on varying defects. Such defects include damage, black spots, dry cuts, grey damage, green areas and rot.

Potatoes will then be classified based on their size, shape and quality into:

Class A <50 Class A >50
Class B
