Sormac B.V.

Sormac offers potato processing equipment for peeling, destoning, inspection, cutting, weighing, conveying, and complete processing lines. Its potato equipment includes carborundum and knife peelers, roller inspection tables, potato cutters, segmenting machines, weighing systems, conveyors and other equipment that can be combined into automated processing lines. Sormac supplies both individual machines and customized systems for fresh potatoes, ready-to-cook potatoes, chilled fresh potatoes, and freshly cut fries.

Industrial potato peeling machines remove the skin using different peeling technologies, mainly abrasive or carborundum peeling and knife peeling. Abrasive peeling removes the outer skin through controlled contact with an abrasive surface, while knife peeling uses precisely positioned knives to remove the skin and imperfections such as eyes and pressure marks. In an automated line, potatoes can first be supplied and destoned, followed by abrasive peeling, knife peeling, inspection and weighing. Sormac combines these stages in its potato peeling lines to achieve consistent peeling and high throughput.

The choice between abrasive and knife peeling depends on the required product appearance, throughput, and processing conditions. Abrasive or carborundum peeling is generally suited to efficient, higher-capacity peeling, while knife peeling produces a smoother finish similar to hand-peeled potatoes and can precisely remove eyes and pressure marks. Industrial processors can also combine both technologies to balance throughput, product quality, and yield. Sormac's potato peeling line uses a roller peeler followed by knife peelers for this type of combined process.

The processing capacity depends on the specific Sormac line and equipment configuration. Sormac states that its potato peeling and cutting line can process up to 2,500 kg of potatoes per hour, while its potato peeling line has a capacity of up to 4,500 kg per hour. Individual machines have different capacities depending on their design and application, so the appropriate system is selected according to required throughput and product specifications.

Industrial potato peeling can improve yield by controlling peeling depth, processing time, product flow, and peeling intensity. Excessive or prolonged peeling can remove unnecessary potato flesh and cause flat peeling, reducing product yield. Knife peeling can provide controlled peeling depth and remove eyes and pressure marks while preserving more of the potato. Sormac also recommends selecting appropriate process settings, including grit, peeling time and machine loading, to help prevent flat peeling and unnecessary product loss.

Yes. Sormac provides complete potato processing lines as well as individual machines. Its integrated systems can combine equipment for supplying, destoning, peeling, inspection, cutting, weighing, conveying and other processing stages. Lines can be configured according to the processor's product, capacity, and production requirements.

The company has developed dedicated technologies specifically for round and tuber crops like potatoes, allowing precise handling across multiple stages. This specialization ensures minimal product damage, optimized yield and high processing efficiency.
