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.

  • High and variable moisture content in biomass feedstocks
  • Inconsistent material composition (wood, ag waste, organics, fines)
  • Dust generation and safety concerns during drying and handling
  • Temperature variability impacting fuel quality and energy density
  • Material degradation from improper thermal processing
  • Buildup and fouling from sticky or fibrous materials
  • Energy inefficiencies in large-scale biomass operations
  • Throughput limitations in drying, torrefaction, or conversion systems

Biomass processing requires precise thermal control, consistent moisture reduction, and equipment engineered to handle diverse, variable organic materials.

Heyl Patterson Thermal Processing designs rotary dryers, rotary calciners, rotary coolers, and advanced thermal equipment used across biomass conversion and biofuel production.

Our equipment supports the transformation of organic materials into renewable energy, fuels, and value-added carbon products.

Biomass Drying & Moisture Control

Moisture reduction is a critical first step in biomass processing. Rotary dryers remove free and bound moisture to stabilize feedstock and improve downstream conversion efficiency.

We deliver:

  • Uniform drying across variable biomass materials
  • Custom flight designs for fibrous, light, or fine feedstocks
  • Adjustable residence time for moisture control
  • High-capacity systems for continuous biomass operations

Efficient drying improves energy output, reduces handling challenges, and prepares biomass for conversion into fuels or other products.

Thermal Preparation for Biomass Conversion

Biomass must often be thermally conditioned before conversion into fuels or carbon-based products.

Our equipment supports:

  • Pre-treatment prior to gasification or pyrolysis
  • Thermal conditioning for consistent feedstock quality
  • Moisture and volatile removal
  • Preparation for pelletizing or densification
  • Stabilization of biomass for storage and transport

Controlled thermal preparation ensures more efficient downstream processing and higher-quality outputs.

Calcination, Torrefaction & Carbonization

Rotary calciners provide indirect, controlled heating environments ideal for advanced biomass conversion processes such as torrefaction, carbonization, and activation.

Heyl Patterson Thermal Processing equipment supports:

  • Biomass torrefaction to produce bio-coal
  • Carbonization for biochar and activated carbon
  • Removal of volatiles for improved fuel properties
  • Controlled thermal conversion of organic materials

Indirect heating separates the heat source from the material, preventing contamination and enabling precise control of the atmosphere for sensitive biomass processes.

FAQs

What types of biomass can be processed using thermal systems?

Heyl Patterson Thermal Processing equipment can handle wood chips, agricultural residues, pellets, organic waste, municipal solid waste (MSW), cocnut husk, fine biomass materials, and any carbon based feedstocks.

Why is drying critical in biomass processing?

Drying reduces moisture content, improves combustion efficiency, and prepares biomass for conversion into fuels or energy products.

What is torrefaction, and why is it used?

Torrefaction is a low-temperature thermal process that converts biomass into a dry, energy-dense material often referred to as bio-coal.

How do rotary calciners support biomass conversion?

They provide indirect heating, precise temperature control, and atmosphere management for processes like carbonization and activation.

Can biomass systems be integrated into existing energy or processing plants?

Yes. Heyl Patterson Thermal Processing equipment are custom-designed to integrate with upstream and downstream equipment, including pelletizing, gasification, and energy recovery systems.
