How do nut manufacturers get the nuts out of their shells?

I have worked in the almond processing business for 15 years. Nuts are in shells that are in hulls. The hulls split at harvest. The nuts are run through beaters to remove the hulls. The nuts with the shells are run through sheer rollers. They are 2 rubber rollers where one rolls faster than the other therby sheering the shells off. There are usually a few of these in a row to allow for different sizes. An air vacuum removes the broken shells. For hard shelled nuts they first go through two steel rollers to crack them.

There are different nuts so different methods are used this is one of them used for Kingnut

Shellbark

The nuts have an outer husk. Like a chestnut, they are dried and then split open to reveal the true interior nutmeat. The shell of the nut is hard and brittle.. There are ridges running from the top to bottom of the nut. The nut is about 1-2" long. The kernel can be broken in half like a walnut. The nut is corrugated and convoluted like a walnut, but flatter and drier. Squirrels love them but humans prefer hybrid walnuts which taste better.
