biomass dryers

When we made our first dryer over 70 years ago, we were driven by exactly what brings you here: We needed a biomass dryer that just workedwe didnt have time to fuss with anything less. We needed a dryer that was reliable, efficient and built with the understanding that capacity is king. So, we made one ourselves. As owner-operators of the same equipment you use, we started and continue making the toughest, longest lasting dryers out there. Were honored to offer that same ingenuity and know-how to you in every wood chip dryer we build today. For you, and for us. Thats Thompson tough. And were sticking to it.

Meet our line of single pass rotary drying systems for biomass. We offer biomass dryers at varying capacities, with single systems having outfeed capacities as low as 1-ton per hour to over 300,000-tons per year (assuming 50% starting moisture content and 10% ending moisture content). Designed to operate for 8,400 hours per year, our biomass dryers are fabricated to the same rigid criteria thats resulted in some Thompson systems running continuously for over 60 years.

A Thompson Biomass XIV can dry temperature-sensitive, organic materials safely at a high capacity with thermal efficiency around 85%; it does so with minimal air pollution, little material degradation and low fire risk. A Thompson Biomass XIV is the most cost effective and energy efficient biomass dryer available today. With Thompsons proprietary internal flighting package, the dryer is able to dry both the small and large chips in your product feed uniformly, inside and out, to the desired dryness.

Benefit: Eliminates the need for make up air Creates a consistent gas flow throughout the drying process Allow drying process to use steam as the heat transfer medium Use less fuel because there is no need to heat make up air Reduces total gas volume entering and exiting the system (no make up air) Either eliminates the need for, or reduces the size of secondary cleanup equipment (lower emissions) Reduces the amount of oxygen entering the system (no make up air) Increases consistency of final product quality Allows for lower temperature drying which protects the quality of the end product

Result: Lower fuel usage means lower operational costs Lower emissions means lower capital investment Lower emissions means happier neighbors Consistent high quality products mean happy customers Personnel and equipment are safer because fires and high pressure events are less likely

Result: Lower operational costs Fewer parts to break which means lower maintenance costs Lower capital investment, no airlock here Lower emissions means lower capital investment in secondary cleanup equipment Lower emissions means happier neighbors Personnel and equipment are safer because fires and high pressure events are less likely

Result: Higher revenues from having more product to sell Lower emissions means lower capital investment in secondary cleanup equipment Lower emissions means happier neighbors Personnel and equipment are safer because fires and high pressure events are less likely

Benefit: Provides data from instruments at key points of the system for information and control purposes to run safer and more efficient Handles startups and shutdowns automatically to remove human error Alarms or controls upset conditions automatically Automated fire suppression system (on some systems)

Biomass is defined as organic matter intended to be used for fuel. Thompson has created a line of dryers to process wet organic matter and prepare it for use as a fuel. Below are some specifications for our line of biomass drying systems.
