Vulcan® Drying Systems Biomass Dryer


Each Vulcan® Drying Systems Biomass Drying System is custom-built for each client. Systems may include the following components:

  • Feed chute or conveyor
  • Rotary Dryer
  • Combustion chamber with burner
  • Secondary air blower
  • Cyclone or Baghouse
  • Induced air blower
  • Controls

Vulcan Sorting Systems Trommel Screens and Vulcan Sorting Systems Conveyors can be used for sorting and transporting Biomass.

Applications & Materials

Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:

  • Agricultural By-Products
  • Animal Feeds
  • Bagasse
  • Biomass
  • Biosolids
  • Hemp
  • Paper Mill Waste
  • Reclaimed Dust
  • Salts & Sugars
  • Sawdust
  • And More

System Process Flow


Biomass is delivered to the feed hopper 1 mounted on a screw conveyor. Air from the auxiliary blower 2 feeds the burner 3, delivering hot gas into the combustion chamber 4. This warm air will vaporize the moisture in the biomass without the flame coming into contact with the material. Flights in the rotary drum 5 move the dried material through the drum where it exits through the knockout box 6 and is discharged from the flap gate 7. The vapor continues to the cyclone 8 for dust collection before being discharged through the exhaust stack 9.

Benefits of the Vulcan® Drying Systems Biomass Drying System

Biomass, the by-product of pulp and paper, agriculture, and municipal sludge, is perhaps the oldest source of renewable energy on Earth. Biomass' use in energy production is currently growing worldwide at an exponential rate. Studies show the by-product could provide up to 14% of U.S. electricity consumption in coming decades due to its clean, sustainable, and economical nature. The demand is present and with multiple challenges associated with drying biomass which need to be mitigated, it's smart to trust the experts at Vulcan® Drying Systems.

When used on a variety of cellulose materials, such as hemp, bagasse (sugar cane waste), brewers grainsgrass, and sawdust, Vulcan® Drying Systems Biomass Drying Systems increase the materials' energy value while also producing a high-quality source of energy.

Processing begins in the dryer. Vulcan® Drying Systems' Direct Fired Rotary Dryers are proven performers, producing a high-volume, low moisture product that is consistent and easy to ship and store. After passing through the dryer, dried biomass is discharged to a conveyor for further sorting. The vapor from the process is pulled through the air pollution control system to remove fine particulates from the vapor stream.

Even though biomass is possibly the oldest source of renewable energy on Earth, when taken through Vulcan® Drying Systems' drying process, it has more added value than conventional biomass. Vulcan® Drying Systems will help you capture a new revenue stream in a biomass drying system while efficiently mitigating the processing challenges that come with air pollution, emissions, and vapor.

About Biomass

Biomass can be created through wood processing, agricultural processes, food processing and even through municipal solid waste (MSW). Biomass waste products can be recycled and converted into fuel, or they can be disposed of through burial or burning.

Burning biomass releases carbon dioxide, a greenhouse gas. Burning wood biomass or biomass from MSW can lead to dangerous pollutants being released into the air.

Regulations created by the Environmental Protection Agency (EPA) are designed to encourage energy recovery from waste, such as biomass, because it is beneficial to the environment, as well as an alternative source of fuel. However, there are some regulations on the composition of fuel created from biomass.

Biomass is a renewable energy source, which is in high demand as many industries look for alternatives to fossil fuels. Since this type of waste is naturally produced in a variety of processes, producers can sell this waste as renewable fuel, meaning that it is disposed of safely and causes no harm to the environment. This also helps producers to save on disposal costs.

About the Biomass Industry

Biomass fuels are made from a variety of organic materials, including scrap lumber, forest debris, crops, manure, and even some municipal waste residues. Since organic waste is readily available, whether from construction and demolition or the paper-making process, biomass is a reliable source of renewable energy.

As of 2010, biomass fuels provided about 4% of the energy used in the United States. Of that 4%, 46% was from wood biomass, 43% was from biofuels, and about 11% was from municipal waste. Researchers continue to work to develop additional ways to use biomass materials as fuel in order to reduce the use of fossil fuels, as well as cut back on greenhouse gas emissions.

Add More Value to Biomass Material

Possibly the oldest source of renewable energy on Earth, biomass produces cleaner energy that creates lower operating costs for power plants. Removing moisture from biomass makes for easier and more cost-effective storage and transportation. Biomass materials can be easily pelletized during this process, which creates higher energy density and results in a highly marketable product.

Vulcan® Drying Systems Biomass Dryers are designed to increase the material’s energy value and produce a high-quality source of energy. Our drying systems produce a high-volume, low-moisture product that is easy to ship and store and add efficiency to your process, helping you to cut operating costs and produce a quality product for market.
