JAF Inox


The company JAF Inox was founded in 2008, originating from the Sartori & Pedroso Food Company, a family owned business and manufacturer of gourmet chocolate. The processing equipment for the production of gourmet chocolate was developed and engineered in-house and was unique in the Brazilian market. After this equipment became very popular among cocoa- and chocolate producers in Brazil, the decision was made to change focus from the production of gourmet chocolate to the manufacturing of small scale and sophisticated processing equipment. This company became known as JAF Inox.


 
JAF Inox can supply complete turnkey chocolate production systems from bean to bar.     The standard lines are economical ranging in capacity from 2½ up to 200 kilos of chocolate per hour.  The assortment of equipment ranges from bean cleaning, roasting, winnowing, and grinding to 5 roll refining, conching, tempering, moulding and enrobing.
