Month: October 2017

I took a look at the duty cycle (on time/total time) for the different bins:

Delage Bins Start End Percent Duty Cycle (on time/total time)

Bin 14 Aug 11 to Aug 21 73.6%
Bin 15 Aug 11  to Aug 21 64.8%

IHARF Bins
Bin 17 Aug 30 to Sep 6   94%
Bin 19 Aug 22 to Sep 6   95.6%

The IHARF bins were on almost constantly. And what is really strange is that the absolute humidity in the bin would increase, even when it was blasted with air that had a lower absolute humidity. I can’t explain it? Maybe it has to do with sensor placement in the bin? Were we really sensing or getting a true sample of the the exhaust air? Or perhaps we just had really good drying conditions for the period of time that we did the run? I would think that the Delage bins would be closer to the norm as far as duty cycle goes.

I have added soybeans and yellow peas to my grain drying calculator at planetcalc.com/4959/   This calculator gives the relative humidity, below which, drying will occur.  It only requires the temperature and moisture % of the grain, as well as the outside temperature and by using EMC equations it calculates the absolute moisture in the air, entering and leaving the bin.  It can be easily loaded onto an Iphone.
