We're not cracking them - we only grow them and wash and prepare them
sufficiently for the factory in West Melton to complete the job which
includes drying to the correct moisture level of the kernel (6%),
cracking, sorting, grading, bagging, grinding, pressing for oil and all
the other products.
They have a 40 channel grader for the cracked nuts at the factory - very
impressive it is too!!
I originally thought of using a Pixy (CMUcam5) which measures hue but at
$5 a pop, the rgb detector looks like a better bet as I can look from 2
sides at once because I can afford more of them :)
