Wyma launches Optical Vege-Trimmer™, an automated optical trimming system for carrots and parsnips

Wyma Solutions has launched the Optical Vege-Trimmer™, an automated optical trimming system designed to remove foliage, crowns and tails from carrots and parsnips before packing or processing. Developed by the company’s post-harvest engineering team, the system combines advanced optical recognition with high-speed cutting to identify each vegetable individually and determine the optimal cut point in real time.

Preparing root vegetables for packing is a key stage in processing lines. Automating trimming operations can improve product uniformity while reducing reliance on manual labour. According to Wyma, the system analyses the shape of each vegetable using optical sensors, calculates the correct cutting point and executes the cut in approximately 0.2 seconds.

Each machine performs top and tail trimming at around two items per second, delivering a throughput of up to 1–2 tonnes per hour, depending on produce size. This approach enables consistent trimming even at high operating speeds, improving the efficiency of vegetable processing lines.

Optical recognition and hygienic design

The machine uses optical recognition technology to identify the unique shape of each carrot or parsnip and automatically adjust the cutting position. Before trimming, vegetables are stabilised using a V-infeed conveyor, which keeps each item correctly positioned to ensure cutting accuracy.

The Optical Vege-Trimmer™ has also been designed for demanding fresh produce processing environments. The system features an EHEDG-inspired hygienic design, including IP69K-rated servo motors, food-grade EPDM seals and components suitable for intensive washdown procedures.

In addition, the open design allows easy access for cleaning and maintenance. Trimmed waste is automatically collected by a base conveyor and transferred to a dedicated discharge point, helping maintain a clean and efficient processing line.

Automation and yield improvement

The system includes an intuitive control interface that allows operators to calibrate and adjust cutting parameters according to product size and characteristics. Once configured, the equipment maintains consistent cutting accuracy throughout the production run.

According to Wyma, introducing optical decision-making into the trimming stage improves processing uniformity and optimises product utilisation. Under certain operating conditions, the system can help increase yield by up to 20%, while improving overall efficiency in carrot and parsnip processing lines.
