For blueberry growers and packers, consistent berry size is one of the most critical factors for pricing. Mixed sizes will lower your product grade, block access to premium supermarket channels and reduce your profit margin.
Manual sorting is slow, labour-intensive and easily causes bruising on fragile blueberries. Vision sorting machines are powerful but come with high upfront costs, which is not economical for many medium and small-scale producers.
Our belt blueberry grader solves this pain point perfectly.
Working Principle of Our Fruit Sorting Machine
Equipped with multi-group conveyor belts and graded discharge outlets, the machine sorts blueberries by size through calibrated gaps.
As blueberries travel forward on the conveyor, smaller berries drop through the first gap and exit from the first chute. Larger berries continue moving to the next stage until they fall into the corresponding outlet.
The gaps can be adjusted freely to match your local blueberry grading standards, such as 12mm, 16mm, 18mm, 20mm and jumbo sizes.
