Cutting line

Potato cutting for human consumption requires great accuracy, and is an important step in obtaining a perfect final product. To facilitate this, Tummers Food Processing Solutions assembles a high-quality cutting process based on your requirements, with a series of innovative cutting technologies.

Step 1: Sorting

Because not all potatoes are the same size, they first enter a continuous sorter on arrival, regardless of their origin. This machine sorts the potatoes based on their diameter and size. The Tummers Fresh Produce Pump then transports the products to the correct cutting head for each diameter. The number of cutting blocks and the blade dimensions selected also depend on the tonnage and the various diameters of the initial product.

Step 2: Cutting

The Fresh Produce Pump transports the sorted potatoes to the cutting block at the correct speed and without damage. Specially-developed technologies also ensure that individual potatoes are separated and reach the correct speed in steps, to guarantee that the cutting process operates optimally.

The patented Tummers Fin aligner then ensures that the potatoes are perfectly centred before entering the cutting block, which avoids damaging them and ensures that the final product always has the optimal length, regardless of the dimensions or shape. The perfect alignment and the Tummers cutting block reduce the chance of “feathering”, which results in an optimal product yield and minimal oil absorption during cooking.

Step 3: Dewatering & sliver sorting

The product, which is cut at high speed, is slowed down on a dewatering belt after the cutting process to prevent damage. A sorting machine subsequently separates the “slivers” that arise during the cutting process from the product with the desired size. Because the slivers can be reused in, for example, a flake or speciality line, none of your product is lost, which avoids wasting food.

Step 4: Water recycling

During the process, the pumping water that circulates within the cutting line is cleaned in a balance tank. Starch sinks to the bottom of the tank, and is removed for other applications, while the purified water is continuously fed back for reuse within the closed system. This water-saving and low-maintenance solution provides you with a controlled water level, with pumping water at a constant quality.
