mobilecentrifugecontinuous

Overview
The JUMBO mobile circulation dryer by STELA Laxhuber is a mobile drying solution for maize, grain and other agricultural products. Designed for energy-efficient continuous drying, it integrates an efficient dust extraction unit compliant with the Federal Immission Control Act (BImSchG). Supplied on a chassis, the unit allows quick relocation and can be installed outdoors or inside existing buildings.

Advantages at a glance

• Fully dedusted: innovative dust separation meeting BImSchG requirements
• Efficient and sustainable: automatic temperature control (Multi-Therm) to minimise energy consumption while maintaining drying performance
• Flexible in use: quick change of location; suitable for outdoor installation and installation in existing halls
• Adaptable: available heating options: direct, indirect or hybrid
• Powerful: designed for continuous operation with optimised energy utilisation
• Gentle drying: automatic temperature management based on drying time to protect product quality
• Quick installation: delivered ready on chassis; no construction works or lengthy approvals required
• Simple and safe operation: user-oriented controls and maintenance access
• Variety purity: good product purity during variety changes and consistent final moisture content

Development
The JUMBO is a further development of the proven MUF mobile circulation dryer family. It offers a compact, fully mobile solution with enhanced dust extraction and improved energy efficiency.

Variants / Key data

• JUMBO 70: Capacity/day – maize 60–70 t (35%→15% / 24 h), grain 110–120 t (19%→15% / 24 h); dryer content up to 16 t; connected load ≈ 49 kW; heating capacity 1,160 kW (direct)
• JUMBO 110: Capacity/day – maize 90–110 t (35%→15% / 24 h), grain 180–190 t (19%→15% / 24 h); dryer content up to 25 t; connected load ≈ 64 kW; heating capacity 1,744 kW

Note on capacities
Drying capacities above refer to cleaned, biologically mature material with bulk density approx. 750 kg/m³ for maize (35%→15%) and approx. 780 kg/m³ for grain (19%→15%) within 24 hours.

Drying principle
The JUMBO circulation dryer combines several components to ensure even, efficient drying:

• 1. Feed hopper: ensures uniform material distribution; suitable for front loader loading
• 2. Shrinkage zone: reduces material volume during drying
• 3. Hot air hood: directs heated air into the drying circuit
• 4. Drying and cooling elements: made of alloyed aluminium for thermal efficiency
• 5. Elevators: internal transport of the product
• 6. Air heaters: provide heated air for the process
• 7. Centrifugal separator: removes dust from exhaust air
• 8. Burner: generates required heat
• 9. Dust downpipe: discharges collected dust
• 10. Fan: ensures required airflow
• 11. Exhaust air hood: access and cleaning opening for adjustments and quality checks
