Parsnip automation project optimises operational efficiency

Frederick Hiam is a family-owned business in the UK that has been specialising in fresh produce for nearly 100 years. The vegetable processor has now partnered with Wyma Solutions to modernise its parsnip processing operations, in a collaboration that spanned two project phases:

1. Phase One: Installation of a new washing and intake line.
2. Phase Two: Implementation of advanced trimming technology, including the Optical Roto-Cut system.

The challenge

Frederick Hiam faced increasing difficulty sourcing labour for manual processing and recognised the need for a solution to ensure operational efficiency. Parsnips, a niche crop, required a tailored approach as off-the-shelf solutions were inadequate.

The solution

Wyma Solutions collaborated with Frederick Hiam to develop and implement the Optical Roto-Cut. The technology uses advanced computer vision systems and was optimised onsite to suit varying crop conditions. Wyma’s expertise ensured seamless integration of the new equipment into the existing factory set-up, even overcoming logistical challenges from phase one installations.

The project delivered significant improvements across multiple areas, including:

• Energy and water savings: 25% reduction in electricity usage and 25–30% water savings.
• Labour efficiency: Frederick Hiam transitioned from 20 manual trimming line operators to two, thanks to automation-enabled consistent throughput of 6 t/h, meeting growing production demands.
• Accuracy and throughput: The company achieved 95% trimming accuracy, reducing crop damage and waste. It also doubled throughput, with benefits extending to supplier and customer satisfaction.

Jamie Lockhart, Managing Director of Frederick Hiam, highlighted Wyma’s collaborative, flexible approach and its commitment to delivering tailored solutions. He praised the build quality of the equipment and the support provided throughout the process. “There are certain moments in business when you just know you’re on the right track. This partnership with Wyma has been transformative for us,” he said.

Frederick Hiam’s factory now boasts one of the world’s first fully automated parsnip trimming lines. This innovation has solidified the company’s position as a leader in efficiency and technology within the fresh produce sector.

The success of the project has opened new doors for collaboration, including a partnership with Burgess Farms to handle all retail parsnip processing. Frederick Hiam has also established a grower group to optimise its supply chain.
