Recently, a Canadian blueberry grower visited our factory. During their tour, they carefully observed the details of the blueberry sorting machine, from the elevator feeding, the pre-sorter screening for impurities, the picking table, to the final sorting outlet. Our factory's technical staff also demonstrated the machine's operation on-site with blueberries and answered the customer's questions regarding sorting accuracy, efficiency, and other aspects of the equipment. Furthermore, we developed a customized sorting solution for the customer based on the size and grade of the blueberries, the size of the sorting area, and other specific sorting requirements.

 This JCSORT blueberry grading machine consists of four parts: a lift, a pre-sorting unit, a sorting table, and a blueberry sorting machine. It can process 800 kg to 1 ton per hour, offering high efficiency, minimal damage to the fruit, and precise sorting. Sorting grades can be customized to meet specific customer needs.

Elevator of the blueberry sizer

Blueberries have thin skins and delicate flesh; any violent impact or friction can damage the skin and cause juice loss, affecting their commercial value. The conveyor belt of the elevator uses the same food-grade, wear-resistant soft rubber material as the sorting machine, with an anti-slip texture and polished surface. The conveyor angle is controlled within the optimal range of 15°-25°, and with soft start and stop functions, the blueberries roll slowly during the lifting process, eliminating free-fall impact. Furthermore, the elevator is equipped with anti-blocking baffles and flexible guide devices to prevent blueberries from getting stuck in the equipment gaps or being squeezed together, further controlling the raw material loss rate to within 0.1%. This synergizes with the low-loss advantage of the sorting machine, echoing the Canadian customer's core demand for "blueberry skin protection."

Pre-sorting of the blueberry calibrator

As a coarse screening and impurity removal step in the sorting process, it mainly removes impurities and obviously unqualified small fruits from blueberries, reducing the pressure of subsequent sorting and improving sorting efficiency.

After pre-selection, damaged or blemished fruits are manually picked out to ensure the quality of the sorted blueberries. The length of the sorting table can be designed according to actual needs.

Blueberry grader

The sieve aperture size is precisely machined according to preset specifications, with manufacturing tolerances strictly controlled within ±0.2mm (up to ±0.1mm for high-end models). The stepped design of the gradient sieve aperture (e.g., 12mm→15mm→18mm) can achieve a grading effect of "no overlap and no omission in size range", with a sorting error of ≤3%, which is far superior to manual grading (error 10-15%).

From wild berries in North American forests to a global superfood, the blueberry's journey has witnessed the modernization of agriculture. Intelligent sorting technology represents the latest chapter in this development. With the further integration of artificial intelligence, the Internet of Things, and big data technologies, future blueberry sorting machines will be more than just sorting tools; they will become intelligent nodes connecting the entire chain of planting, processing, and sales. They will be able to predict market trends, optimize planting plans, and even participate in the decision-making process for new variety development.
