Modular drying solutions that adapt to your processes – rely on 30 years of experience.

Drying systems from Alraun Maschinenbau GmbH

Your reliable partner for modular drying solutions since 1990

In our production facility in Staig near Ulm, we develop and produce modular drying systemsthat can be individually adapted to a wide range of drying requirements. Our goal: maximum quality, maximum flexibility, and sustainable cost-effectiveness for your production processes.

Our systems consist of a conveyor belt and the associated drying tunnels, intermediate tunnels, cooling tunnels, and exhaust air tunnels. Thanks to our modular concept, all components can be configured precisely to your requirements and subsequently adapted, expanded, or optimized at any time.

Drying system from the modular system, flexible & mass-produced

Continuous dryers for industrial applications – standardized & individually combinable

✔ Customer assembles his drying system individually – perfectly tailored to his process
✔ Selectable Drying technologies:
• Infrared (IR) medium and long wave, pure radiant energy without air movement, up to 250 °C, digitally controlled
• Warm air, uniform volume flow (0.5–0.75 m/s), up to 150 °C, digitally controlled
✔ Available Drying widths: 30 cm, 50 cm, 70 cm, 90 cm (fixed)
✔ Drying lengths can be selected modularly – each heated drying unit is 60 cm long, can be combined to any total length
✔ Exhaust air modules in 30 cm length with connection piece Ø 100 mm for the removal of moisture or gases
✔ Flow height as standard 100 mm, optionally on 25 cm, 30 cm or 40 cm increaseable
✔ Each drying tunnel with its own power and control electronics for precise control
✔ Modular design – ready to use, combinable & integrable into existing systems

Belt conveyors from Alraun Maschinenbau GmbH

Conveyor belts & belts – flexible & adaptable

✔ Conveyor belt/belt in the lengths 200cm, 300cm, 400cm, 500cm, 600cm and the widths 30 cm, 50 cm, 70 cm, 90 cm
✔ Conveyor belt height adjustable, tiltable and mobile on castors – can be placed anywhere
✔ Conveyor belt with different belt variants:
• food safe
• closed
• Teflon-coated mesh belt
• glass mesh reinforced and more

Drying system & conveyor technology – modular, flexible, series-produced

The perfect system for your drying application – individually configured, modularly expandable & reliable.

✔ Drying tunnel in 30, 50, 70, 90 cm width, always 60 cm long, with IR or warm air technology up to 250 °C / 150 °C
✔ Exhaust air modules in 30 cm length with Ø 100 mm connection
✔ Conveyor belt/belt in 200–600 cm length, 30–90 cm width, height adjustable, tiltable & mobile on castors
✔ Different belts: food-safe, closed, grid, Teflon, glass grid
✔ Standard clearance height 100 mm, extendable to 25, 30 or 40 cm
✔ Modular combinable, ready for immediate use & easy to integrate

Your benefits at a glance

✅ Modular & flexible
Our drying systems are modular in design. They adapt to your processes – not the other way around. Whether you want to increase your drying capacity, increase the throughput height, or retrofit additional modules: everything is possible.

✅ Ready for immediate use & individually combinable
Each module is delivered plug-and-play and can be easily integrated into existing systems. Various drying technologies (infrared, warm air) as well as widths (30 cm, 50 cm, 70 cm, 90 cm) and flow heights (up to 40 cm) are available.

✅ Reliable quality & many years of experience
For more than 30 years, customers from a wide range of industries have trusted our expertise. We manufacture exclusively in our German factory and provide personal support from planning to implementation.

✅ No costly drying tests necessary
Our experience and flexible system design enable theoretical design without complex preliminary tests – saving you time and money.
