Paturpat, a company specialized in processing and marketing steamed potatoes, has opted for TOMRA's Orbit steam peeler, because of the advantages it offers during the peeling process and to the final result.

The Orbit steam peeler system is qualified to peel different food products, such as potatoes, almonds, apples, carrots, sweet potatoes, pears, peaches and peppers. In this case, Paturpat has chosen the Orbit 250l model, because it offers high performance compared to other machines on the market for its objective: the production and subsequent sale of steamed potatoes, which are sold vacuum-packed in different formats (for salads, whole peeled, etc.). In so doing, this staple food is converted to a product that can be consumed in different ways, without losing its natural quality or nutritional value.

Pedro García, Sales Engineer at Luciano Aguilar S.A., distributor of TOMRA machines on the Spanish vegetable market, said: “Some time ago Paturpat contacted us and told us about their project. We provided them with several options, took them to see other factories that are similar to theirs and we performed demonstrations of the machine. Thus, they decided to go for the Orbit. They opted for the 250 liters version, appropriate to their production.”

The complete range of Orbit peelers includes an ultra-fast vessel decompression system. This system is one of the key features for achieving superior peeling performance. With less steam, Orbit peelers guarantee maximum quality of the peeled product. It has been shown that the Orbit range achieves good peeling results starting at 9-10 bars of steam pressure, where other machines do not get similar results below 12 bars.

Other key features of the Orbit technology are its geometry and peeling vessel rotational speed, specifically designed to avoid steam condensate on the inside. This prevents cooking of the product.

“The Orbit 250l peeler allows to adjust times and steam so that the peeling is done without the cooking effect, which is limited to the next step. This advantage is very important to us because, after having completed several R&D studies, we did not want to start the cooking process of the potatoes in the peeling zone. And of the various options that we explored, it was TOMRA that offered us this advantage,” ensures Iratxe Arce, production manager at Paturpat.

“The possibility to work at less than 12 bars was a decisive advantage to choose TOMRA over other peelers,” Iratxe Arce says.

“The Orbit peeler minimizes the cooking effect on the potato during the peeling process, which is limited to the outer 2-3 mm of the potato surface crown. In contrast, other solutions in the market cause a cooking of 10 mm or more of the potato surface. This surface cooking is an undesired effect, because even when the potato is blanched in later stages of the process, the final product will be more irregular and heterogeneous in texture between layers, lowering its quality. All this is possible because we achieve the best peeling quality with the lowest steam pressure and the shortest cycle and without generating condensates in the peeling vessel.”

The Orbit machines contain a complete sensor system that provides information to the control system. This system regulates and optimizes the functioning of the machine based on two basic parameters: the desired line capacity and the time the product stays in the vessel. And that is the main goal of the Orbit series: increasing efficiency. In other words, achieving maximum quality and yield with the lowest operational cost possible.
