Changsha, China — As global edible-oil production accelerates, oilseed processors are seeking equipment that delivers higher yield, cleaner operation, and more stable throughput. TangChui Rolls Co., Ltd. (TC Roll), a leading manufacturer of alloy mill rollers, today announced its upgraded line of oilseed cracking and flaking rollers designed for sesame, sunflower, and rapeseed processing lines. Engineered for heavy-duty performance and long service life, the new roller series offers a significant efficiency boost for modern oil mills.
Matching Oilseeds with the Right Roller Technology
Oilseeds differ greatly in hardness, shell composition, and oil content. Sesame seeds require tight cracking gaps and high surface grip; sunflower seeds need hull-fracturing without kernel pulverization; and rapeseed requires precise, uniform cracking to expose oil-bearing cells without producing fines. TC Roll’s updated cracking and flaking roller series targets these material challenges with tailored surface processing, optimized roller hardness, and customizable corrugation designs.
TC Roll’s Cracking Rollers: Engineered for Yield, Safety & Stability
TC Roll’s oilseed cracking rollers feature centrifugal composite casting, combining a high-alloy nickel-chromium-molybdenum outer layer with a durable cast-iron core. The alloy layer of 25–30 mm and surface hardness of HS75 ± 3 ensure exceptional wear resistance during continuous operation.
Key advantages include:
-
High-efficiency cracking for better cell rupture and improved oil extraction.
-
Reduced dust generation, lowering explosion risk in processing plants.
-
Reliable continuous crushing, enabled by ribbed/corrugated roller surfaces.
-
Simplified maintenance thanks to TC Roll’s stable mechanical structure.
-
Full customization (Ø100–500 mm, length 500–3000 mm) for integration into existing processing lines.
High-Precision Flaking Rollers for Pressing & Solvent Extraction
For plants requiring thin and uniform flakes, TC Roll offers a complementary range of alloy flaking rollers (diameters up to Ø1000 mm, hardness HS40–HS95). These rollers ensure even pressure, minimal surface deviation, and consistent flake thickness — crucial for maximizing oil-yield performance in pressing and solvent-extraction systems.
Lower Life-Cycle Cost Through Maintainability
TC Roll also provides flaker-roll grinding equipment, enabling mills to recondition roller surfaces in-house, extend service life, and reduce downtime. Combined with TC Roll’s wear-resistant alloys, the total cost of ownership can be significantly lower than imported brands while delivering comparable or superior performance.
Driving the Next Generation of Oilseed Processing
“For sesame, sunflower, or rapeseed processors, the roller is not just a mechanical component — it defines extraction efficiency and product quality,” said a spokesperson for TC Roll. “Our new cracking and flaking roller series is engineered to help mills achieve higher yield with stable, safe, and cost-effective operation.”
