Single Disc Dryer
The Dryer One™ “Single Disc” dryer is an ideal solution for lower production capacities (compared to the “Double Disc” model), for drying with lower-temperature air, and when the volume of water to be evaporated is less significant. It is particularly recommended for input materials with lower moisture content, as well as for applications requiring lower drying temperatures.
The material to be dried is distributed over a rotating disc through which a flow of hot air (50 to 100°C) passes, coming from an external low-temperature energy source such as a cogeneration unit or a boiler.
One of the key features of the “Single Disc” dryer is its ability to recycle the air that has passed through the product at the end of the drying cycle—still dry and warm—by redirecting it to the beginning of the cycle to pre-dry the wet material, thus optimizing the system’s energy efficiency.
After passing through the layer of material, the saturated, humid air—cooled to a temperature of 25 to 30°C—is discharged through the central chimney.

IN The rotating platform is supplied with material to be dried. |
 |
DRYING The material to be dried rotates 360° on the rotating platform. |
 |
OUT The dried material is discharged to the packaging or storage area. |
 |
HOT AIR INLET Hot air is drawn from top to bottom through the platform. |
 |
EXTRACTION & EXPULSION OF MOISTURE-SATURATED AIR The moisture-saturated air is pulsed upward to be expelled. Any dust can be filtered. |
 |
ENERGY RECOVERY SYSTEM Excess energy available at the end of the drying cycle can be recovered using a recirculation fan and reused at the beginning of the cycle, where the wettest product is located. |

The material layer is passed through by a flow of hot air. Subsequently, the used air, saturated with water and cooled to a temperature of 25 to 30°C, is expelled through the central chimney.
To optimize the energy performance of the device, the “single disc” dryer can optionally be equipped with an energy recovery system, allowing excess energy from the “dry” zone to be captured and reused in the “wet” zone.
In addition, the outer casing of the dryer is fully insulated.
Low-temperature dried materials generate extremely low levels of pollutant particles.
An integrated fire detection and extinguishing system, combined with the use of primarily non-flammable materials that prevent the spread of fire, makes the Dryer One™ a piece of equipment with an extremely low fire risk, enhancing the safety of the production site.
The circular shape of the Dryer One™ minimizes its footprint, allowing easier integration into existing production sites.
The advanced automation system of Dryer One™ optimizes efficiency, precision, and safety. Fully automated, it requires minimal operator supervision, ensures precise control of the moisture content, and enables the generation of production reports.
Dryer One™ dryers are compatible with various low-temperature heat sources, such as hot water, hot air, or steam, produced by biomass boilers, natural gas burners, or cogeneration installations.
