Stainless steel tanks for the preparation of honey require internal heating in combination with slow vertical stirring with paddles. Product heating is achieved through heating jackets or serpentine or a combination of both. Their bottom can be either flat or conical. Their capacity and dimensions are chosen after consultation with the customer. The construction material of these tanks is stainless steel AISI 304 with internal finish 2B and external Fioretto, with certificates of chemical analysis from the steel mill. The weldings are done with the Argon Tig method in a protective atmosphere of high-purity inert gas.
