Soybean shelling machine DOSB

sunflower seedhigh-capacityvertical

Overview
The versatile impact dehuller DOSB is engineered to efficiently dehull sunflower seed, soybean and cottonseed for edible oil production. Its adjustable impact cone allows precise control of the dehulling degree, making the machine suitable for multi-seed plants.

Key benefits

• Continuous and safe operation: built-in permanent magnet at the inlet and material level probes at inlet and outlet interrupt feed in case of backup and stop the machine if necessary.
• Gentle dehulling for high‑protein meal: hulls are ruptured and detached from kernels without crushing, producing low‑fines, high‑protein extraction and improved pressing results.
• High production flexibility: wide range of applications and an easily adjustable impact cone for different seeds and operating conditions.

Highlight features

• Easy maintenance: wear‑resistant steel lining and accessible design for quick removal and replacement of wear parts.
• High throughput: vertical design achieves up to 180 metric tons per day for sunflower seed while keeping a compact footprint.
• Low fines generation: impact cone geometry minimises fines, enhancing extraction and pressing performance.

Other features

• Adjustable feeder with permanent magnet for removal of ferrous contaminants to protect product and machine.
• Material level probes to monitor flow and prevent blockages.

Process integration
The DOSB dehuller integrates into oilseed processing lines (intake, handling, cleaning, dehulling, hull separation and control, flaking) to deliver efficient dehulling and hull separation for maximised yield and product quality.
