Soybean shelling machine OLHA

stainless steelhigh-capacity

Overview
Bühler’s Fluid Bed OLHA is applied in the second stage of soybean hot dehulling to pop soybean hulls, reduce soybean moisture and prepare material for efficient downstream oil extraction. The unit integrates a built-in conveying system, accurate drive and full thermal insulation for consistent processing results.

Key benefits

• Efficient processing – The built-in conveying system controls kernel heat exposure during hull popping to deliver high-protein results and transfers the processed product to the discharge airlock.
• Economical design – Full thermal insulation reduces heat loss and lowers operating costs.
• High throughput – Straightforward design supports easy start-up, uncomplicated operation and consistent product quality at high capacity.

Highlight features

• Controlled popping – Gear motor drive precisely operates the conveyor to maintain product layer height and control retention time for optimal popping.
• Easy maintenance – Large service doors provide convenient access to major components for fast cleaning and upkeep.
• Durable materials – Rugged steel frame and stainless steel product-contact parts (aspiration hoods, directional sieves, air inlet channel, product chamber) extend component lifetime and reduce lifecycle costs.

Process chain (typical steps where the fluid bed is applied)

• Raw material intake
• Handling (in-plant conveying)
• Drying (oilseed drying)
• Storage
• Weighing
• Cleaning
• Conditioning
• Cracking
• Hull separation
• Hull control (recovery of kernel particles from hull stream)
• Flaking (downstream to pressing or solvent extraction)

Services and training
Services and training are available to support operation, maintenance and process optimisation, including spare and wear parts, consulting and expert services to ensure availability and performance.
