Automatic Potato Weight Sorter: Grading into 7 Size Classes by Weight in One Pass

In this video, we show how SameGram's automatic weight sorter grades raw potatoes into 7 weight-based size classes in a single pass — no manual labor, no guesswork, just consistent, accurate grading at production speed. Whether you pack for retail, supply food manufacturers, or integrate weighing into a larger packaging line, uniform weight grading is the difference between premium pricing and rejected lots. Here's how it works and why it pays off. ▶ What the system does SameGram's dynamic weight sorting system performs 100% inline weighing on the moving belt and automatically diverts each potato into one of up to 20 customizable weight grades. For this potato application, the line is configured to 7 grades — from small seed stock to large baking potatoes — with grade boundaries set entirely to your specification. ▶ Key capabilities (SameGram weight sorter platform) Grading levels: 1–20 weight grades, fully customizable — 7 grades demonstrated here Weighing accuracy: ±0.3–2 g, depending on model and product Throughput: belt speed 5–90 m/min; tray-based models up to 300 units/min Gentle handling: soft pushers, buffer arms, or air-blow reject — protects delicate skins and reduces bruising Hygienic build: 304 stainless steel, IP65 rated for washdown in wet, dusty environments Up to 20 reject channels with flexible structures per grade Easy line integration: connects with conveyors, packing lines, and auto-rejection modules; supports ERP / traceability data output ▶ Why it matters for your operation Fruit & vegetable farmers / growers: turn a bulk harvest into priced grade bins and capture more value from large, uniform stock. Food processors: feed downstream peeling, cutting, or cooking lines with consistent-weight batches for predictable yield. Manufacturing & automation owners: replace manual sorting labor with a reliable, 24/7 grading station. Product distribution / fulfillment centers: standardize inbound produce weight for accurate packing and invoicing. Packaging integrators: embed a proven weight-grading module into your turnkey lines. ▶ Proven in the field A poultry processor in Nakhon Ratchasima, Thailand upgraded to SameGram's SWSR-750TC6 multi-level grader to meet strict Japan/Korea export standards. Results: daily throughput rose from 10 to 18 tons, grading accuracy reached 99.3%, and product damage dropped 60% — unlocking new supermarket contracts and +18% export potential. The same grading logic applies directly to potatoes and other produce. SameGram weight sorters are built for food, farming, and livestock lines where consistent quality and traceability drive competitiveness.
