Biology:Pea sheller
From HandWiki
Short description: Apparatus designed to take out peas from their pods
A pea sheller is an apparatus designed to take out the peas from their pods. Early models were powered by hand, via a crank; later models are powered by electricity. Certain models can also be used for beans.
The mechanical pea sheller was invented in the 17th century.[1] Typically they press the peas between two rolls, which squeeze out the peas; sometimes the rolls have ridges that slice the pods open. Pea shellers have different types of mechanisms to separate the shells from the pods and other debris.[2] Washing machine rollers can be used, for instance.[3] Currently, pea shellers are made in the US by Welborn Devices of Mississippi, and Lehman's Hardware of Ohio.[4]
