Three-Mode Dryer Boosts On-Farm Efficiency

The Trilogy Series low-profile dryer is available in three different sizes—T2030, T2440 and T2850—and with both propane and natural gas options.   
 
 

Mathews Company introduces the Trilogy Series of low-profile dryers, featuring three interchangeable modes. The dryer modes are full heat, pressure heat/pressure cool, and pressure heat/vacuum cool—previously only available on tower dryers. Thanks to the technology, farmers can maintain their current setup and receive the energy efficiency of vacuum cool, without incorporating a tower dryer.

The technology on the Trilogy Series reclaims heated air from cooling the grain, resulting in less fuel usage and dollar savings of up to 20% or more.

After blending ambient air drawn from outside, the preheated air is returned to the fan. This, in turn, lowers energy consumption and produces maximum efficiency. Research by Mathews Company shows that as the grain travels vertically downward through the dryer, its temperature is elevated during the drying process.

At the final stage, the heat, which would otherwise be expelled to the ambient surroundings, is transferred as incoming (cold) air through a heat transfer process. As the grain cools, the incoming air is preheated and a reduced amount of heat is required to elevate the air’s temperature to the desired heat plenum operating set point.

The Pinnacle Lite–based control system comes standard on all Mathews Company dryers. The system includes a built-in fail-safe mode that enables the user to operate the dryer in manual override with zero downtime, as well as flip-of-the-switch control between drying modes. The Trilogy Series dryers are available in three sizes—T2030, T2440 and T2850—and with both propane and natural gas options.

The Trilogy project was partially funded through a grant made available from the Propane Education and Research Council. For more information, visit www.mathewscompany.com.
