Technical advantages
This is what distinguishes mandrake from standard dryers.

Modular building block system
Assemble your continuous dryer, belt dryer or tunnel dryer exactly to your needs.
Drying widths of 30, 50, 70 or 90 cm and modular lengths (each heated unit 60 cm) allow for any total length.
Subsequent expansions are possible at any time – your drying system grows with your production.

Selectable drying technologies for optimal results
Choose the right technology:
• IInfrared dryer (IR): – Medium and long wave, pure radiation energy without air movement,
up to 250 °C, digitally controlled
– ideal for fast and gentle surface drying.
• Warm air dryerr – uniform volume flow
(0.5–0.75 m/s), up to 150 °C, digitally controlled
– perfect for the homogeneous drying of your sensitive products such as herbs, hemp or grains.

Precise and reproducible process control
Utilize independent power and control electronics in each drying tunnel for maximum accuracy.
Exhaust air modules (30 cm length, connection Ø 100 mm) reliably remove moisture and gases.
Adjust the passage height to 100 mm as standard, or optionally to 25, 30 or 40 cm.
– for maximum flexibility with your different workpieces.
Ideal for fixing and curing surface coatings.

Conveyor belts & belt technology – flexible and adaptable
Choose the appropriate belt conveyor in lengths from 200 to 600 cm and widths from 30 to 90 cm.
Set up your conveyor belt in a height-adjustable, tiltable and mobile position on casters –
This allows you to place it exactly where you need it, regardless of location.
Benefit from belt options such as food-safe, closed,
Teflon-coated mesh tape or glass mesh reinforced – optimally tailored to your application.

Energy efficiency and durable industrial quality
Reduce your energy costs through optimized heat utilization and minimal downtime.
Rely on robust steel construction, maintenance-friendly design and long-term spare parts availability.
Your industrial dryer “Made in Germany” is a safe investment for reliable continuous use.
Find the right belt dryer, continuous dryer or tunnel dryer for your application – we configure it exactly to your requirements.
