Olds College research shows in-bin grain drying could be economically viable


Olds School has been engaged on a multi-year undertaking on in-bin drying, which was on show at AgSmart at Olds, Alta.

The expertise, developed by High Grade Ag, at Calgary, Alta., makes use of a proprietary algorithm with stress, temperature, and humidity sensors to optimize the grain drying course of.

Daniel Stefner of Olds School says the system works with a small sensor within the plenum of the bin, and one within the attic.

“It’s mainly measuring the delta — or the distinction between — humidity and temperature, and stress between the 2, to give you a moisture removing estimation,” he explains. “So what we’ve been doing at Olds School is calibrating and validating these readings to see how correct these moisture removing estimates are.”

Regardless of the drought that plagued a superb portion of the Prairies by way of 2021, the school was in a position to check the system utilizing a moist bin of canola, in addition to six dry bins that wanted to be cooled down.

“By way of these occasions, we discovered that every one of their estimations have been inside 0.16 per cent of the particular moisture content material as soon as they have been dried down,” says Stefner.

The analysis staff additionally did vitality consumption calculations to validate and examine the inexperienced drying metrics of doing in-bin drying, versus a typical grain dryer.

“For one occasion we had final 12 months, we took 11.6 per cent moisture content material canola, and dried it down to eight.3 per cent. In order that was about three days of supplemental warmth added. After which two days of calm down. It was below two cents per level per bushel for dry down. So we have been very, very happy with that,” he explains.
