What makes a tanker food grade?

Clean clean clean. When I hauled food grade and specialty I'd drop the tank at the tank wash and ask for a food grade wash. When I picked it up, I had to make sure the tank, valves and bleeders we're completely dry and all the valves and caps were sealed. If you're a company driver, dispatch has the responsibility to send the last 3 loads that specific trailer contained (may be more or less than 3, it was 3 where I worked). Probably at least a 6,000 gallon tank, or compartmented

 

Food grade tanks have liners made of a material that can be cleaned and disinfected properly. Some of the old ones were glass lined but they may have a stainless alloy or some kind of composite they use now.

 

Maybe you can tell me. What is with all these guys I see around here washing mixers and cement bulkers with Ty D Bol? There’s 3 different outfits I’m aware of that are at that.

 

I think they’re using using it on the paint work of the trucks. They acid the trailers. The one guy is even more old fashioned than I am. He’s got a couple of DM’s that are ancient and the rest are R models, so none of them are new. But they’re bright red. There’s not one in the yard that’s the standard sun bleached dog turd pink for a Mack that age. That has me thinking the old buck is onto something.

 

The tank wash certifies then as clean. I imagine a "food grade" designation would come after inspections checking valves and liners etc.

In generic terms, "food grade" is a tanker with no internal baffles. It may be called that even if it nevers hauls anything edible.

 

No baffles.
