Dryer Selection Guide

Material Handling: Specific materials require careful handling, demanding appropriate settings for intake, distribution, and outtake.

Target Evaporation Rate: Tailored to each project, our dryers adapt to the moisture gradient, dictating the air volume needed for evaporation. This customization allows for optimal dryer surface sizing and accommodates specific material drying speeds, volumetric throughput, and project-specific evaporation capacities.

Desired Moisture Level: Maintaining consistent, uniform moisture content is essential for achieving optimal drying quality.

Heat Source: The choice of belt dryer technology is influenced by the available heat source at your facility (such as waste heat, steam, or thermic oils), aligning with its capabilities and ensuring the lowest cost of operation (OPEX).

STELA Belt Dryers: Flexible and Efficient

Heating Source Adaptability

Our dryers are versatile, handling thermal oil, saturated steam, and waste heat from CHP and ORC. This flexibility boosts your energy efficiency by leveraging the heat you already produce.


Compatible Heat Sources

Boilers running on gas, renewable, or fossil fuels can all power STELA Belt Dryers. The dryers are engineered to integrate with your energy supply, effectively using available resources.


Heat Medium Versatility

Efficient with various heat mediums, our dryers are optimized for water, thermal oil, and saturated steam. They provide consistent, uniform heating, essential for quality drying.


Optimized Energy Use

STELA Belt Dryers enhance drying efficiency and reduce energy consumption, seamlessly integrating with existing energy systems through a combination of low and high-temperature heating cycles.

The Stela Low Temperature Belt Dryer: A Three-Tiered Approach

Our belt dryers are meticulously structured, operating seamlessly across three distinct levels:

Upper Level – Heating Section: At this level, our focus is on the preparation and conditioning of the ambient air, ensuring it’s adequately warmed up and tailored for the drying process.

Mid-Level – Drying Excellence: This is where the drying magic happens, with a systematic approach to material distribution and preparation for moisture extraction.

Lower Level – Airflow Release: As the drying process concludes, this level efficiently handles the moisture-laden exhaust, ensuring a clean and environmentally-friendly operation.

Airflow Configurations: Airflow Configurations: Our dryers are designed to support process belts with top-down airflow. These belts are segmented into zones along their length, allowing multiple drying zones to be ventilated sequentially using the same airstream. You can select between single-pass and recirculating air systems. Additionally, we offer the option to incorporate an exhaust air heat recovery system and condensation unit for improved efficiency.
