Peeling line

The peeling process

Perfect potato peeling will provide you with a high-quality end product with minimal peel loss. The steps in the process are determined by the condition of your potatoes, the required end product and your capacity. We will provide the optimum combination of equipment. Optionally we can also convert the emissions back into hot water that can be used for other purposes. This ensures you of a sustainable, emissions-free peeling unit.

Step 1: Supply

Following the washing process, the potatoes proceed to the peeling line, where they enter the peeling drum via a weighing hopper. Accurate control of the filling weight ensures an optimal balance between peeling yield, capacity and steam consumption.

Step 2: Steam peeling

During the steaming process, the peel is separated from the potato. The Tummers steam peeler has been developed for optimal yield, minimal maintenance and low steam consumption. The filled steam drum rotates at high speed, which exposes the potatoes to the steam evenly. The water under the peel is heated to above 100⁰C. The blow-off system then causes a sudden drop in pressure, the water turns into steam, and the potato peel is loosened. The peeled product is subsequently transported to the next step in the process via a discharge screw.

Step 3: Dry peeling

Following the steaming process, a brushing machine removes the peel from the product. Depending on the desired peeling result and the required capacity, we install either a U-Brusher or an innovative ZicZac-Brusher. The brushes in these machines separate the potato peel, which is subsequently removed. As no water is used during the brushing process, the peels remain suitable for further processing into, for example, animal feed.

Step 4: After Washing

Finally, after washing systems remove any remaining peel residue and loose starch from the product. The products rub against each other and the drum wall, which together with water ensures a perfectly clean final product. After washers are available as Drum washers, or as Washing screw conveyors. The washing water is continuously filtered and reused, to guarantee minimum consumption.
