Mobile grain dryer JUMBO 70

continuouscentrifuge

Overview
The JUMBO mobile circulating dryer is a mobile drying unit for agricultural products such as maize and cereal grains. It is equipped with a centrifugal dust extraction system compliant with the Federal Immission Control Act (BImSchG), enabling a clean working environment and installation outdoors or inside existing buildings.

Advantages at a glance

• Fully dedusted: centrifugal dust separation in accordance with BImSchG guidelines
• Energy-optimised control: automatic temperature control (Multi-Therm) to reduce energy demand while maintaining the set drying profile
• Flexible deployment: quick relocation and easy outdoor or indoor installation
• Multiple heating options: direct, indirect or hybrid air heating available
• Durable operation: designed for long service life under continuous use
• Gentle product handling: automatic temperature control adapted to drying time to protect grain quality
• Fast commissioning: no major construction works or additional approvals required in most cases
• Safe and simple operation: intuitive controls for on-site staff
• Consistent final moisture: uniform moisture at the end of the drying cycle and supported variety purity during product changes

Product description
The JUMBO is the successor to the MUF mobile circulating dryer. Its design focuses on a compact, mobile layout with integrated dust extraction to meet agricultural site requirements. The unit handles cleaned, biologically mature wet material and provides controlled drying for maize and other grains.

Note on drying capacities
Drying capacities above refer to maize (cleaned, biologically mature, bulk density approx. 750 kg/m³) from 35% to 15% in 24 h; and to grain (cleaned, biologically mature, bulk density approx. 780 kg/m³) from 19% to 15% in 24 h.

Drying principle

• 1. feed hopper: ensures even distribution of material, suitable for loader charging
• 2. shrinkage zone: reduces material volume during drying
• 3. hot air hood: directs heated air into the drying chamber
• 4. drying and cooling elements: high-quality alloyed aluminium components
• 5. elevators: internal material transport within the dryer
• 6. air heaters: provide the required heating for the drying air
• 7. centrifugal separator: separates dust particles from exhaust air
• 8. burner: heat generation for the process
• 9. dust downpipe: dust discharge from the dryer
• 10. fan: ensures required airflow
• 11. exhaust air hood / access: access and cleaning opening for adjustments and quality checks
