Shaking program Bijlsma grading machine can be optimally adjusted for each variety

Adjustable shaking intensity

No potato (variety) is the same and Bijlsma Hercules takes this into account. They allow the user to electronically control the shaking intensity and speed on the new BSM 2113/4 grading machine. The shaking speeds and the duration can be set independently of each other. “This allows the potato grower to set and store the optimum shaking frequency for each variety to be sorted, fully geared to the tuber characteristics of the batch,” says Jan Bijlsma.

Grading machine drive

The grading machine is driven by a three-phase motor equipped with a frequency converter and an electronic controller. This drive ensures that the screening boxes with removable screens make alternating movements. During the high shaking speed, the product will be transported over the sieves, while at the slow shaking speed the product will have the opportunity to fall through the sieves. With the stop option, the movement is briefly stopped. In this way an optimal separation can be made in the product.

Maximum 40 tons per hour

The model that is prominently displayed on the stand at AgriTechnica is equipped with fully rubberized screens. The rubbers can rotate independently of each other and therefore move with the potato and are therefore wear-resistant. Changing the sieves is done in an instant by unlocking the clamp construction, after which the sieves are simply slid out and into the sieve boxes. The switch side can be executed on both the left and the right side, so that the machine can be built into existing sorting arrangements. In addition, the machine is available with 4 or 5 sieve decks to sort 5 or 6 sizes respectively and to deliver a capacity of up to 40 tons per hour.
