Measuring moisture levels on grain that is moving through a dryer at up to 10,000 bushels per hour (250 metric tons) is a complex task. There are many areas where variability can be introduced into the process.
Brock set out to eliminate this variability with their patent-pending TrueGrain™ Moisture Sensor System. It uses what the company calls Parallel Sensing Technology™ to measure grain moisture in an entirely different way than other dryer systems.
Most dryers measure variable heights of grain flowing across horizontally mounted moisture sensors. With the TrueGrain system, grain is diverted through a vertical chamber at a constant speed using a metering wheel. This uniform sensing area prevents fines and condensation from accumulating which could distort measurements.
A temperature probe also located in this area is isolated from swings in ambient temperature. The metering wheel provides convenient access to grain samples for manually cross-checking moisture content.
John Tuttle, vice president of sales and marketing for Brock Grain Systems, says the TrueGrain System is a breakthrough in accurate and efficient grain drying.
“There is nothing else like this in the industry that moves grain past parallel sensors in a vertical chamber inside the dryer,” Tuttle notes. “It’s a unique way to eliminate outside factors that could distort moisture readings, and to give Brock dryer owners the most accurate grain drying possible.”
The new TrueGrain Moisture Sensor System is only available on BROCK® Commercial Tower Dryers, MEYER ENERGY MISER® Tower Dryers and Brock SUPERB ENERGY MISER® Low-Profile SQ Series Dryers. It works with Brock’s INTUI-DRY® Controller to provide moisture-based dryer control and remote monitoring.
