Expeller

An expeller is a big machine that helps crush things like seeds, nuts, or grains to get oil out of them. Imagine a really big and strong hand squeezing a toy until its insides come out. That's kind of what an expeller does, but with much bigger things like seeds. The expeller crushes the seeds until they break apart and release the oil. The oil is then collected and used for lots of things like cooking, making soap and lotion, or even fuel for cars. So basically, an expeller helps get oil from seeds and nuts by squishing them really hard.
