During the roasting process, the cocoa beans are constantly tumbling inside a slowly rotating stainless steel vat. The beans are heated by convective heat (heating element) and conductive heat (from the oven drum) to get an even roasted bean.
Peculiarity：
Stainless steel is hygienic and easy to clean
Roasting roller - used to roast beans evenly
2-4 lbs (1-2 kg) - ideal for lab-scale or professional-scale operations
0-120 minutes analog timer
Heating elements at the top and bottom of the convection and conduction units – efficient heating
