I own a tripe shabu-shabu restaurant, and cutting tripe slices is really tiring. Is there any machine that can cut tripe into size: 2.5 cm long, 2 cm wide and 1 to 2 mm thin?

What you are cutting is an oblique knife. The knife must be sharp. The machine is just a slicing knife, but tripe is very flexible. Even a machine slicing knife can ensure that the thickness of tripe is even. I am a chef. I can tell you for sure that no machine can do the issuance like yours, but no one has invented a machine that can do it. Your future will only be done by hand
