Needs more heat

Mike Durns had about 160 of his CanDri grain dryers at work this fall.

One of his customers is the Dundurn Colony in central Saskatchewan. Levi Wollman is boss of grain drying at the colony. He says the colony is located in an area where they can’t really justify the investment in an expensive dryer.

“That’s a lot of money for something you hardly ever use, so we never did buy one. But we saw the price on the Cyclone dryer and how it took out moisture. That made sense to us. We had very good results with that Cyclone this year,” Wollman said.

The colony has two 60,000 bushel bins. When they used the new Cyclone on both bins, they each contained about 40,000 bushels. Both bins are equipped with a six sensors.

“We dropped the moisture from 17 percent down to an average of 13.5 percent. That’s the average. That’s good, but it’s not the whole story. Grain at the bottom of the bin will be drier and grain at the top will have more moisture.

“The bottom was down to maybe seven percent moisture and at the top it was 14.5 to maybe 15 percent. But it was average 13.5 percent. We sold it all to Cargill for blending. This drying was in good weather. If you were doing this in minus weather, I don’t think it would work that good. Mike is saying now that 40,000 BTUs isn’t enough (in some cases). He’s going to get bigger heaters.”

Wollman says that even in good weather, the maximum grain temperature they attained was 35 C. Wollman thinks they need 45 C to do a better job.

“The other thing is you have to remember to turn the heat on in daytime and turn it off at night, but let the fans keep running at night to push all that heat up through the grain.

I watched the sensors and the temperature and I could tell exactly what that grain was doing. Mike is going to have it all automated by next year, so that will be a very good thing.”
