When the manufacturer makes peanut butter, are the shells also used?

Here is a video of making peanut butter.

Probably with the machine designed to deal with that.

The peanuts come to the factory already shelled.

Yes, @Kayak8. But at some point they go through the shelling machine.

Kayak8, thanks. I watched the 4 minute video and now I am an informed person of how peanut butter is made.

I still would like to know how they separate the shells from the peanuts.

Have you ever eaten peanuts with the shells? That is, just pop the unshelled legume into your mouth and crunch away? (I don’t do boiled or raw peanuts; I’m talking about ‘regular’ peanuts in the shell.)

For some reason they taste more like peanut butter when I’m crunching away on the shell, too. I can’t figure it out.

@john65pennington Perhaps clicking on links might help with that.

The Whole Foods that I go to, has peanut butter making machines with transparent tubs. From what I can see, the peanuts are thoroughly shelled.

Peanut shells can be used in animal feed.

Klutzaroo, do all of those machines just shell peanuts? I would like to see peanut shelling in a video.

This is one of the video links you could have clicked on, @john65pennington. This machine shown in this video is giving people in Uganda dreams of being budding capitalists. I love it.
