APPARATUS FOR HEATING GRANULAR MATERIALS

摘要

APPARATUS FOR HEATING GRANULAR MATERIALS An apparatus for heating granular material such as mustard seeds, peanuts, cacao beans, coffee beans, and soybeans includes an inclined cylindrical drum forming a heating chamber. The material is fed to the heating chamber through an upper tube which also feeds hot gas into the chamber. Microwave energy is fed into the lower end of the chamber which is provided with an internal structure of concentric rings and longitudinal strip members to assist in mixing of the material.
