Bijlsma Hercules grading machines stand out for their unique riddling speed drives. This mechanism has electrical controls. High and low riddling speeds and duration can be adjusted separately. This enables optimum riddling frequency for each tuber shape, under any circumstances.

The heavy-duty design of the crankshaft combined with electrical drive ensure the machine's quiet operation, even when it is mounted on a support frame, as in bulk hopper installations, for example.

An extremely accurate partition.

When grading elongated-shaped tubers, it is desirable to have the machine running with pauses. With high riddling speeds, the tubers are transported across the riddles in order to release the necessary capacity. In low riddling speeds, the tubers are given time to fall through the mesh of the riddles. This ensures accurate separation of the various grading sizes.

Our Bijlsma Hercules grading machines are available in different models, depending on your capacity needs you can choose one that fits you the most.
