Any non-corroding stainless would probably qualify as food grade. Types
304 & 316 are readily available and should work fine. The "food grade"
requirement, in a commercial setting, is usually described
"Examples of acceptable equipment materials include some types of
stainless steel, various plastics and laminates. Some types of stainless
steel can corrode. Stainless steel that can corrode is not acceptable for
food processing facilities. It is very important that equipment and
utensils be constructed of food grade materials so as not to create a
health hazard to consumers."
For personal use those requirements don't necessary apply and you could
even use mild steel as long as you took precautions to see that it didn't
get a chance to rust.
The instructions said to use Windows 98 or better, so I installed RedHat.
The biggest issue I know of, from a guy who used to make food processing
equipment, is that the welds must be flawless. If there any pits or
imperfections in the welds bacteria can't be washed off during cleaning and
therefore contaminate the food. Welds must be ground/machined flush &
304 or 316 is the typical alloy used for food grade equipment
If you go to a welding supply shop just ask for filler wire for TIG welding
304 or 316 stainless... they should have several sizes available
