Biomass Processing & Conversion

Our commitment to cutting-edge technology and sustainable practices positions us at the forefront of the biomass sector. Our experienced engineers and professionals excel in custom-engineering machinery such as rotary calciners, rotary dryers, fluid bed dryers, and our multidisc thermal processor, all designed to handle biomass materials for sustainable energy production.


Activate, torrefy, and carbonize any carbon-based feedstock in a completely integrated system.

Our rotary calciners are designed to handle biomass processes with combustible, oxidation-sensitive, or heat-sensitive materials. They separate the heat source from the material, making them perfect for turning biomass into charcoal or conducting torrefaction to convert biogas into a coal alternative.

  • Constructed from materials to withstand high temperatures and corrosion
  • Gas flow designs for same or opposite direction airflow
  • Operates at temperatures up to 2200°F (1204°C)
  • Sizes available over 100 feet (30.48 meters) in length and up to 12 feet (3.6576 meters) in diameter
  • Configurations available for various heating zones
  • Suitable for dehumidified, inert, oxidizing, or reducing atmospheres

Our rotary dryers are versatile and can handle a variety of feedstocks for processing biomass bulk solids. Manufacturers can set parameters like moisture content, biomass temperature, and retention time, with options for cooling either externally or internally (with integrated cooler design).

  • Airflow systems include forced-draft, induced-draft, or combined options
  • Compatible with various control systems
  • Lifting flight design for efficient conveying and drying
  • Gas flow designs for same or opposite-direction airflow
  • Operates with inlet gas temperatures up to 2200°F (1204°C)
  • Sizes over 100 feet (30.48 meters) long and up to 16 feet (4.8768 meters) in diameter

Our fluid bed dryers efficiently handle free-flowing biomass materials using an energy-saving fluidizing method to improve heat transfer rates. Fluid beds are highly efficient compared to other dryers. They come in circular, trough-type, or vibrating designs, providing flexible solutions for biomass processing.

  • Supports various control systems
  • Cylindrical design option for back-mixing with continuous or batch flow
  • Options for processing lumpy, sticky materials
  • Features stainless steel or high-temperature alloy bedplates
  • Handles inlet gas temperatures up to 2200°F (1204°C)
  • Available in diameters up to 18 feet (5.4864 meters)
