Anyone measure actual shrink on corn during drying??
I'm pushing a pencil between building another drying bin and commercial storage. Their 1.4% shrink seems a little steep, but I'm finding conflicting numbers in the extension service.
Never measured it myself, so I'm asking.
I'm trying to figure shrink from say, 22% down to 15%.
Commercial is .03/point + 1.4% shrink, or about $0.80/bu total @$6 corn.

I have weighed grain in and out of bins with just a fan, no heat several times. It has worked out to about 1% per point every time

I THINK actual shrink is 1.2.

I'm finding tables with 1.2-1.3%. Just a wag, from eyeballing shrink in the bin, I was thinking around 1-1.1%. Never actually measured it.
This is a bin with burner and stirrator.
Sounds like my guess is in the ballpark.

Actual shrinkage is 1.17% per point dried, but there is always handling loss. While the elevators around here stick us for 1.4%, I use 1.25% for my farm dried stuff and it seems to capture what little handling loss I have.

I find 1 to 1.25% with more closer to 1.25. . 1.4% may sound high, but you basically are not touching it. I don't think elevators are trying to stick it to anybody at that rate.

I wasn't thinking the elevator was sticking it to anyone except on the drying cost. They are a little over a penny per point high, compared to what I can dry it for.
Shrink? Just never knew actual numbers, just went of the extension service charts and they are usually a little generous to allow for variation.
