Sunflower seed shelling machine DGBB

high-capacityimpactstainless steel

Overview
The sunflower impact dehuller DGBB uses proven impact-dehulling technology to separate hulls and kernels with minimal waste. Designed for oilseed processing, it delivers controlled dehulling with throughputs of up to 180 metric tons per day and can be supplied as a single machine or integrated into a complete dehulling line.

Key benefits

• Flexible processing: Four setpoints allow adjustment to different seed moisture contents and sunflower varieties.
• Efficient dehulling: Impact plate design reduces damaged seeds, fines generation and oil impregnation effects.
• Consistent product quality: Horizontal feeder ensures uniform seed distribution across the rotor width.

Highlight features

• High availability — Easy maintenance and reduced downtimes: Large maintenance doors for fast access; fast-change rotor, beater plates and impact plate; accessible feeder for cleaning magnets and adjusting the feed slide gate; inspection window for product flow checks.
• Rugged design — Reliable operation: Sturdy frame with vibration pads to limit vibration and noise; durable rotor, beater plates, impact plate, magnets and seals for low wear and long service life.
• Dehulling solution — Single machine or integrated line: Available standalone or as part of a complete sunflower dehulling solution including hull separator, cleaner, flaking mills, hammer or pellet mills, conveying systems and more.

Application possibilities

• Primary application: Oilseeds processing, specifically sunflower seed dehulling prior to pressing or extraction.

Process chain (relevant production steps)

• Raw material intake: Grain intake and storage systems for continuous supply.
• Handling: In-plant conveying systems (elevators, trough chain, belt and screw conveyors) customised to space and process needs.
• Drying: Gentle, uniform oilseed drying to maintain kernel quality and enable safe storage.
• Storage: Multiple options (flat-bottom silos, steel silos, silo bins) for seeds, hulls, meal and bulk materials.
• Weighing: Precision weighing and dosing for accurate process control.
• Cleaning: Efficient removal of impurities (broken seeds, straw, stones, dust) to maximise yields.
• Dehulling: Rugged impact dehuller providing high throughput and control over dehulling degree.
• Hull separation: Screening and aspiration to separate loose hulls from the good product stream.
• Hull control: Recovery of valuable kernel particles from the hull stream to optimise yield.
• Flaking: Flaking mills for preparation prior to pressing or extraction.

Services and training
Services and operator training are available to support installation, commissioning and ongoing operation, improving availability, cycle times and process monitoring.
