combining soybeans that froze

Operator is having touble with alot of un threshed pods in tank. Operator hasnt had any issues I guesss until mine. Any ideas on setting machine setting changess? IH 1640. Also, most beans are normal, although small this year. Moisture is 11-12%. We are some green beans, some oblong shriveld ones. All due to that early sept freeze. Hope the elevator doesnt dock me too bad. Also, very, very dusty combining.Either way I am glad to be getting the beans off.
 
If the beans are not splitting, speed up the rotor and close down the concave.

I have had to run as high as 800 on the rotor when normal is 500 or so.

If the concave is set close enough and its still doing it,then you probably need to wait a few days.Have you run a moisture check on them yet.They should be at 13% or lower
 
I looked at his last unload that is in the wagon. Alot of split beans. How bad does a guy get beat up at the elevator with the pods? Should we maybe close the seives, turn up the fan?
 
If not too many splits I would do as LaGary said and close down the concave and run the rotor faster. IH recommended a concave setting of 4 and rotor speed of 400 rpm. I had to set the concave at 3 and run the rotor speed between 550 and 670 rpm to get all the pods threshed. Slowed it down to 550 when the sun came out and were getting too many splits. I run a squirrel cage fan at max speed but have two airfoil seives which require a lot of air. If you are getting too many splits and can't speed up the rotor or close the concave, I would, as you mentioned, increase the air and slightly close the shoe sieve which will increase the tailings. Hopefully the increased tailings will be the unthreshed pods and not just beans which could again result in too many splits
 
The last line of defense regarding what goes into the grain tank is the lower sieve. It is letting pods through. Need to close it some. That increases trash in the tailings, so may need to close the concave some or lastly, increase cyl (rotor) speed. Remember that speed makes feed. (splits in beans, crackage in corn, etc)
 
Possible that those pods are immature and empty? They might not thresh no way-no how. Open your returns door and run em on the ground and see what you see. Might be better off dumping the pods on the ground instead of sacrificing sample quality trying to thresh them.
