Drying Beans.

[Arrow1]

We are going to need to dry some Beans next week and have never done so before.
Plan on putting through a master mobile kerosene dryer.
Can’t find any settings in the book and wondering if anyone has any ideas.
I have heard that they are tricky.
Thanks.

When I dry my beans with the mobile dryer I heat them up and then leave them overnight. I leave out the cooling phase because you need the heat to get into the bean. Try testing the beans in the morning and see if you need to put some more heat on. It's steady work but this method usually works. As you say they are tricky.

Okay thanks,that sounds worse than I thought.
First load going on Friday so better get a move on.
Any idea on what temperature you can take them to?

I usually get the beans to about 40 degrees I wouldn't go any higher or they might split. If they have lasted this long in storage they are probably only 17-18 % so won't need too much drying. I had to dry them from 23% once and that was a real pain.

I’ve found that you mustn’t use too high a temperature with them because they will split and they take an absolute age to warm up. Then because the husk is so thick, they take a hell of a long time to actually come down in moisture.
They also take a hell of a long time to cool down too.

In cereals, we stop the heat 1% above what we want them to end up at, as the cooling process starts when they are still hot and the will end up at the correct moisture by the time they are cool. But with beans you might find you can stop the heat 2% above what you need them to end up at.

Last time I dried beans in our continuous flow drier we were limited to 40 degrees C. Wetter ones went around twice. Once we'd cooled them slowly to avoid splitting, we ended up with overdried beans. Hey ho. The merchant didn't mind as they were export grade & the Egyptians like them much drier anyway.

low and slow

These are around 17% and going for feed.
Does it make much difference if they split?

I'd check the terms of your contract - there are probably max tolerances to split seeds. The fact that the first thing they will do is to grind them up is irrelevant!

At 17% cant you just sell them and accept a claim? Probably cheaper than drying them

Alot cheaper I would say

Trouble with that is if they are 17 %and you want them to be 15% you have to stop the heat before you have started.I know it doesnt make sense but I find it easier (more consistent ) to dry wheat from 18 to 15 than 16 to 15
