Paint for old extractor

I have an older galvanized 2 frame Pender extractor, the frame holders have some steel in them which is rusted, I have cleaned them as well as I can and thought if I painted them with food grade paint I could still use the old extractor, trouble is I am having trouble find suitable paint. Any Ideas please.

I have an extractor over 80 years old. I wouldn't paint any surface inside the tank. If you extract honey and don't wash the extractor afterwards, you'll leave a film of honey that will provide some protection agsinst rust. I only wash my extractor just before using it ........ and .... it's better to have a little rust in the honey than particles of paint. Richard - Sydney.

I have exactly the same problem with the same equipment though I think the drum is more the issue - and I am pretty sure that (at least) the last drainings of honey taste a little metallic. I don't like the idea. The bulk of honey spends little time in the drum so should be OK. I too had looked at a food quality paint but came to a dead end.

It struck me today that it COULD be possible to coat the inside with beeswax! My drum never gets hot enough to melt beeswax.

I might have a go at warming the can from the outside and rubbing a block of beeswax over the inside. It would be awkward, but might solve the problem. It may cause problems with small quantities of wax sticking to it during extraction but it may be worth a try.

Something else that might be worth a shot is a "rust converter" based on tannic acid. This leaves a highly tenacious highly insoluble black Ferric tannate. A treatment with this and then with beeswax might also be worth a shot

A little "iron oxide" (rust) won't hurt you. Of course if you are selling honey you would need a stainless extractor I expect and definitely no paint. I would eat rust all day long before ANY kind of paint! I think if you remove the scale and coat with wax it would be worth a try.
My thoughts only, no medical idea on rust consumption!

I am a beekeeper and painter, I also have a pender 2 frame extractor with a little rust in the drum and more on the baskets, I called penders no replacement baskets available, so then I priced the cost to sandbalast the rust and buy the food grade paint (which is available I can get info of the source) then spray it works out much dearer than buying a 2 frame extractor new, so for my money I will buy new thanks Len
