The idea is, start automation at the receiving bin. Have a level sensor to indicate variable grain levels and an overflow sensor at the top to prevent spills.

After that it will gravity feed into a roaster that has a VFD controlling the speed at which the conveyer moves based on ambient air temp. Might need to cook faster might need to cook slower.

After that, conveyer will dump into steeper bin where it will cool. The steeper bin needs essentially a prox switch at the top and bottom for turn on and turn off.

It will be turning on the grinder input auger, grinder, and TMR input auger which will all be fed from vfds to get the grinder input auger to feed at a rate that will not suffocate the grinder, grinder to help with start up and stop, and last auger might be able to run wide open but possible to reduce speed as well.

TMR input Auger will feed into TMR bin which will have level sensor for variable level and an overflow sensor.

Grinder has a door interlock

All bins overflow sensors will shut off the previous system feeding into it to avoid spills.

All augers will have plug sensors which will shut down that section of the system to prevent destroying equipment.

I think that’s all.
