Dear Mr. Marcelino,

perhaps you will find much more information if you seek around foodstuff industry and inhouse materials handling re belt conveyors.

As a mechanic I used to wprk in a inhouse foodstuff logistics company, they had a product line entirely made from stainless steel.

There's conpanies out there who would give you an insight, for some info you might look into http://www.transnorm.com/index.php?id=882&L=0 (disclaimer: not related to said company).

Regards
