Potato processing line by Marcelissen
Designing and manufacturing a potato processing line is something that requires a lot of attention. The potato is, of course, a well-known product that is eaten all over the world and therefore has many different applications. Let’s start at the beginning, the processing process is immensely important since the quality of the product deteriorates if the production process is not handled properly. This requires a tailor-made solution and a partner that listens and understands your wishes and process. Co-engineering is therefore a concept that is very important to us. We put this into practice for all our potato lines.
Figure 1: Example production line from Marcelissen
A production line for potatoes consists of several links within a larger whole, each with its own function. The production line is made up from our wide range of machines. For more information about the complete portfolio of machines, click here.
Machines within a production line
The number of links within the processing line depends on the customer. We will zoom in on three links to give you an idea of the different processes within the overall production line.
U-bed Roller Peeler – SKRT
Figure 2: U-bed Roller Peeler – SKRT
One of the first links in the potato line, after entering the factory, is the U-bed Roller Peeler – SKRT. As the name indicates, the potato skins are peeled off in this stage. This is done by using rollers which are covered in a desired size of carborundum. This results in the fact that the skin is slightly scraped off from the potato, ensuring a nice peeled product. However, some customer want their product to have a hand-peeled look as well as increased shelf life (when selling whole potatoes). In order to achieve this, a Knife Peeler can be used after the Roller Peeler for the ‘finishing touch’, making them look hand-peeled.
This specific type of Roller Peeler has carborundum rollers which together form a trough. One half of the rollers rotates anti-clockwise, the other half rotates clockwise. A constant supply of products is of great importance for the peeling quality. That is why an auger has been mounted inside the trough that determines the transport time of the potatoes through the machine. By means of a frequency converter, the speed of both the rollers and the screw can be determined. Furthermore, peeling with little or no water is possible.

Drum Knife Peeler – SMT
Figure 3: Drum Knife Peeler – SMT
The Drum Knife Peeler is used for peeling root crops such as potatoes. It can therefore ideally function as a follow-up step to the roller peeler, as a combination of both ensures the best possible result.
Video: A Drum Knife Peeler demonstration
The Drum Knife Peeler consists of a frame with a very stable AISI 304 drum and auger. The product is peeled during transport. If necessary, the knife bars can easily be removed or replaced. By means of cleaning beams, the inside of the drum can be cleaned without reducing the peeling capacity.
An important advantage of the peeler, is the fact that the special construction ensures an optimal rotation of the product where 100% peeling is guaranteed. This machine is also perfectly suitable for steam peeled potatoes and can be supplied with touch panel or control box.
The beams that hold the knives are made of 304 stainless steel, guaranteeing hygiene. More details about the Drum Knife Peeler can be found in the table below.

Continuous Halving Machine – DC
Figure 5: Continuous Halving Machine – DC
A machine that often comes after peeling potatoes is the Continuous Halving Machine and the Start/Stop Halving Machine. As the name suggests, at this stage the potatoes are divided into two or four parts. The option exists here to apply both ways simultaneously via several lanes
Video: Watch how the halving/quartering machine works.
There are three parts within this cutting machine, namely the infeed conveyor, roller bed and cutting section.
The infeed conveyor ensures that the product is placed single and in lanes on the roller bed. This roller bed consists of diabolo rollers so that a perfectly centred position of the potato can be ensured before the potato enters the cutting section. The cutting system is mechanical and able to perform a continuous cutting movement. Due to this unique construction, a high degree of capacity and efficiency is achievable.
The cutting section is located at the end of the roller bed. Here, depending on the mounted knives, the product is cut in two, four or even six pieces.
Finally, there is a conveyor belt underneath the machine, on which the product is collected and can be inspected a second time if necessary. The capacity is 55,000 potatoes per hour.
The Process
The end product naturally determines the way in which a potato processing line is constructed. Each potato speciality therefore requires a specific production process, which means that certain machines are or are not required for your situation. At Marcelissen we have all possible links at our disposal and shape them in such a way that the customer can achieve the end result that he or she wants. By doing so, the optimal potato line is set up specifically for your situation. How flexible we are in determining and manufacturing your optimal solution, when it comes to identifying the requirements, we use a fixed approach:
- Identification of customer’s wishes & needs (sketching)
- In cooperation with Engineering and R&D, the most optimal solution is determined for each project. Only when we agree on the best suited solution does the actual engineering start, always in co-creation with the customer.
- Production
- Testing phase
- Installation at the customer’s site
- Commissioning of the production line
- Evaluation & feedback
- Service & maintenance
