LOW MAINTENANCE COSTS

We train your staff in operation and maintenance. We produce the spare parts for the DRYON fluidized bed dryer ourselves at our site in Gleisdorf.

How does our fluidized bed dryer work?

Our drying plant is based on an innovative system that guarantees efficient and gentle treatment of a wide variety of materials.

Material feeding: The material is fed onto a perforated conveyor floor. Hot air flows through the perforations during drying, or cool air during cooling. The material moves transversely to the air flow, and the process thus operates according to the cross-flow principle.

Material loosening: The bulk material is loosened either purely by the air flow in static dryers or with the aid of additional vibration. This flexibility allows optimal adaptation to different materials.

Static fluidized bed dryers 

A static fluidized bed dryer or fluidized bed cooler works exclusively with air loosening; heat exchangers can be integrated here:

  • Can be used for fine grain sizes up to 6 mm
  • High throughput on a minimal footprint
  • Integration of heat exchangers 
  • Significantly reduces the amount of air required
  • Reduces the size of the unit
  • Larger layer heights enable smaller footprints

Vibrating fluidized bed dryers 

The vibration enables optimal drying even at low flow rates:

  • Ideal for coarse grains and drying bulk materials with a wide grain spectrum
  • Three different vibration systems depending on requirements
  • Variable residence time control through vibration adjustment
  • Easy product changeover thanks to good emptying properties

Why is fluidized bed drying so important?

Fluidized bed drying plays a crucial role in many industries, as it creates the conditions necessary for subsequent production steps:

+ Preparation for subsequent process stages: The drying process ensures that the material can be further processed. This guarantees the screenability and separation of fine material by sorting machines.

+ Reduced transport costs and improved storability: The increased surface stability of the material optimizes storability. The material can be handled more efficiently and transported more cost-effectively.

+ Consistent product quality: Fluidized bed drying ensures consistent product quality. Thermal drying is often a critical step in achieving the desired properties for a saleable or marketable product.

Reduction of CO₂ footprint 

Our technology aims to reduce CO₂ emissions during the drying process to a minimum. By utilizing internal waste heat streams and integrating external energy sources (photovoltaic systems, furnace exhaust gases), we offer an environmentally friendly and efficient solution.

Frequently asked questions about our fluidized bed dryers

Compared to drum drying, fluidized bed drying requires less heat. The cross-flow principle ensures faster drying with lower thermal energy requirements.

In a belt dryer, the material is transported on a moving belt while warm air flows through the material from above or from the side. In a fluidized bed dryer, on the other hand, the material is loosened, fluidized, and then surrounded by hot air. This technology offers ideal heat transfer and faster and more uniform drying than a belt dryer.

Although fluidized bed dryers are efficient and versatile, there are some limitations:

  • Moisture: The material must be free of free liquid. Free liquid must be removed in advance by mechanical dewatering. However, this is recommended anyway from an operating cost perspective.
  • Material sizes: Fluidized bed dryers are limited to materials with a particle size of 0 to 70 mm, depending on the specific material.

Yes, fluidized bed drying is also used successfully in agriculture, for example in alfalfa drying. Here, the benefits of efficient and uniform drying, which ensures high-quality products, are clear.

Grain drying requires longer residence times, which are difficult to achieve in fluidized bed drying. In this case, shaft dryers or other systems that are specially optimized for such requirements are used.

The fluidized bed dryer is available in various sizes. For smaller applications, there are models with a width of 200 mm and a length of 1500 mm. However, larger machines can also be up to 3 x 20 meters in size, depending on the feed rate and material size.

  • Static fluidized bed dryers: Smaller footprint thanks to greater layer heights.
  • Two-mass oscillation system: Sizes up to 60 m². This machine type is particularly suitable for higher feed rates.
  • Single-mass oscillation system: Sizes up to 16 m².

Drying systems are usually controlled according to the exhaust air temperature. This method offers the advantage of being virtually maintenance-free and very precise at the same time. If necessary, the moisture content of the output material can also be measured in order to control the drying process even more precisely. However, this additional control option is only used in individual cases where even more precise control is required.

Our drying systems are characterized by exceptional durability. Numerous dryer systems have been in successful use for more than 30 years. After decades of service, many systems are simply converted or expanded instead of being completely replaced. The robust design ensures reliable and economical use for decades.
