As the blueberry sector continues to focus on efficiency and gentle handling, new technologies are emerging to meet rising quality demands. A new optical sorting solution will contribute to that, says Piotr Milewski, CEO of Milbor PMC: “Our MXM Sorter BN.2 represents the latest generation of optical sorting solutions for the blueberry industry. Designed and manufactured in Poland by Milbor PMC, our new machine integrates high-capacity, precision sorting while maintaining great fruit gentleness. The system employs a dual-camera module with 2K resolution, enabling high-speed analysis of each berry’s surface characteristics.”

Using image-based data, the sorter classifies fruit according to three categories: Size, ripeness, and softness of the fruit, Milewski explains. “This precise optical evaluation allows for consistent removal of undersized, unripe, or overripe fruit, improving the uniformity and commercial quality of the final product. With a processing capacity of up to three tons per hour, our new sorter combines high efficiency with a compact footprint. The design facilitates integration into existing packing lines without major layout changes, making it particularly suitable for pack houses with limited space. It can also be an addition before the grader, to improve its capacity by removing under- and over-ripe berries first.”

Milewski hopes that this sorter helps fill out a certain niche: “Browsing the blueberry sorting market, we spotted a niche: growers who require quality sorting but do not need to categorize fruit with a grader. That is why we designed and engineered MXM sorter BN.2. This is a reliable sorting machine for growers managing plantations exceeding 30 hectares or packing plants processing volumes above 500 tons annually.”

According to Milewski, every mechanical element of the sorter is engineered to minimize stress on the fruit. “Stainless steel construction and silicone transport belts ensure durability, corrosion resistance, and gentle handling of the fruit. Our objective was clear: to provide the minimal drop height within the sorting path that reduces bruising and preserves the natural bloom of blueberries. It is an important factor influencing both appearance and shelf life.”

The hygienic design philosophy of this new sorter provides direct access to individual components, enabling quick cleaning and maintenance, Milewski emphasizes. “The open-frame structure and smooth surfaces reduce cleaning time by up to 90% compared to conventional sorters, ensuring consistent hygiene standards and minimizing downtime during the peak season. The machine is operated through an intuitive HMI interface. The control system allows users to configure sorting parameters, monitor machine performance, and export operational data for traceability and reporting. Such automation enhances repeatability and reduces dependence on operator experience, improving process reliability across multiple shifts.

Overall, Milbor is ready and excited to supply this newest machinery to the world: “Developed and assembled in Poland, the MXM Sorter BN.2 is designed for integration within automated packing environments and can operate as a standalone sorting module or as part of a larger grading system. Its flexibility makes it suitable for producers employing mechanical harvesting or those seeking to expand existing optical grading capacity,” Milewski concludes.
