We are different from the others!

JOPER roasters are proudly handcrafted in Portugal by master craftsmen, out of traditional high-quality durable materials such as cast iron and carbon steel.

Cast iron is proven to be the fundamental material for building coffee roasters – proof of that is the durability of the old roasters from several brands that used cast iron and the low quality of those that are recently built.

Cast iron has thermal inertia and an exceptional radiation capacity for heat retention. As a result, the heat is more even and stays longer than in any other material. Some of the cast iron properties make it the ideal material for making coffee roasters: its melting point is relatively low, has good fluidity, excellent machinability, resistance to deformation, wear, destruction, and weakening by oxidation. Therefore, it is perfect for building strong, robust, and durable roasters.

Obviously, they become much more expensive equipment economically, but JOPER is firmly committed to the construction of cast-iron roasters. JOPER is also the only one to manufacture the main bearing supports on the drum also in cast iron, precisely for the excellent efficiency and durability.

The result of almost 6 decades, and continuous improvement, JOPER roasters combine time tested traditional highly durable materials with the best industrial quality modern burners, motors, fans, and controls to produce an easy to use, flexible, quiet, low maintenance, energy efficient roasters capable of running 24 hours per day.
