In this case, the client wants to wash beets and carrots at 10 tonnes per hour. Spiessens provided a cost-efficient solution. Below, you can follow each step of the process.
In the first step of the process, the product is fed into a de-stoning cyclone. Here, the stones and the product are separated from each other. The product is propelled to the pre-washer and the bricks sink into the cyclone. These are then transported on a conveyor belt to a box.
In the second step, dirt is removed from the product by means of the pre-washer. The drum is driven by V-belts. A manual control slider is provided to regulate the dwell time in the washer.
Below the washer is a rotor filter that will filter all the water from the washer. The dirt is discharged into a box and the filtered water flows into a water tank. The water is then pumped up again to the de-stoner cyclone.
After peeling, the product falls into a dosage screw and is then transported to the brush belt. The purpose of the brush belt is to remove the peeling waste from the product, without using water.
By means of a conveyor belt, the product is pressed against twelve brushes. The peeling waste is removed via the underside of the brush belt. At the top, the product falls back out.
In the final step of the process, the product is washed once more in a post-washer to remove any small particles that may still be adhering to the product.
