Working demo of Bühler SPARK Colour (Optical) Sorter at LAMMA shows how the right equipment helps farmers add value on farm

With margins under pressure, every investment in new farming equipment must deliver clear value. Bühler UK's SPARK colour sorter offers farmers just that - a reliable, high-quality way to improve grain quality, efficiency and profitability in post-harvest operations.

"We're looking forward to showing LAMMA visitors the superb engineering behind the Bühler SPARK," said Scott McArthur, Project Division Director, McArthur BDC. "It's built to last, easy to use, and designed to deliver consistent results on farm."

The SPARK is simple to operate via a touchscreen control panel, allowing farmers to monitor performance in real time. Each chute has two dedicated cameras, unlike other sorters on the market which have two cameras for multiple chutes, which target unwanted grains. Self-cleaning mechanisms keep the machine running efficiently while reducing maintenance.

"When designing a colour sorter into a grain plant, no matter the size, it's vital to work with an experienced integrator who understands both what you want to achieve and what's possible within the constraints of the project," McArthur added. "Every detail matters to ensure the sorter performs reliably on farm."

"Our grain cleaning and sorting specialists design every installation around the farmer's needs - from achieving the necessary throughput, meeting crop specific specifications to the seamless integration of the colour sorter with other processing equipment. There is also a focus on the practical details too, like easy access for calibration and day-to-day operation."

Using cameras and sensors to remove discoloured grains, weed seeds, ergot and other unwanted material, the SPARK produces cleaner, more uniform grain. This helps farmers get better prices, reduces the risk of rejections or deductions from grain merchants, and even recovers grain that might otherwise be downgraded.

By accurately targeting the problem kernels, the SPARK reduces waste while supporting the highest standards of feed and food safety.

"LAMMA is the perfect opportunity for visitors to see our post-harvest solutions up close and understand the real on-farm value they bring," concluded McArthur.
