I made an apple peel itself

Summary by Krater

The creator builds and tests an extreme high-pressure steam peeling machine designed to peel potatoes and other fruits and vegetables, experimenting with pressure settings up to 200 PSI.

Answers: Can a high-pressure steam machine peel a potato?

• High pressure steam peeling machine
• Potato peeling experiment
• Pressure cooker physics
• Hydro testing pressure vessels
• Belleville washers
• Stainless steel fabrication

What it concludes

• A potato can be successfully peeled using extreme high-pressure steam, stripping the skin instantly when the pressure is released.
• Higher pressure and temperature settings are more effective at cleanly removing the skin of fruits and vegetables like potatoes, apples, and tomatoes without damaging the core.
• Belleville washers effectively absorb the thermal expansion stress in high-pressure boilers and prevent structural failure of the threaded rods.
