Process Description :
When the agitator rotates, the Material is carried radically around the inside of blender. Outer & inner ribbons move the material in opposite direction. Thus the triple mixing action takes place. The Roaster is provided with M.S. Jacket, which is filled with special purpose heating Oil. The Heating oil in the jacket is heated by Electrical operated Oil immersion Heaters, inserted from the pocket at the corner Mixer. Once the oil in the jacket' is heated, the material in the container is uniformly mixed as well as roasted. Electronic Digital temp controller controls the required Temperature of heating. It is ideal to set the Themerature at 1800 to 1900 C. while roasting. The oil heating can be carried out with Gas instead of Electrical heaters as per the Customer requirement.
