Stainless steel oil storage tanks with conical bottoms based on INOX legs and have a closed conical roof. They offer incomparable ease in the total emptying of the product as well as in their internal cleaning on a cone at the bottom. They are manufactured in almost all dimensions and capacities vary between 1.0 m3 and 60 m3. In addition, there is the possibility of controlling the temperature of the olive oil by installing a cooling-heating jacket. The construction material of these tanks is stainless steel type AISI 304 with internal finish 2B and external Fioretto, with certificates of chemical analysis from the steel mill and certificates of suitability for olive oil processing. The weldings are done with the Argon Tig method in a protective atmosphere of high-purity inert gas.
