Title: Rotary drum dryer and operating method thereof
Inventor: HORI KEIICHI
IPC: F26B17/32
Filed: 2000-02-04
Abstract: PROBLEM TO BE SOLVED: To dry rice and rice cake in particle free from lumping. SOLUTION: Rice and the like is fed into a rotary drier 11 through an objective feeding pipe 21. On completion of feed, hot wind and microwave are supplied inside the rotary drum 11. In a first operating step, the rotary drum 11 is intermittently rotated while heating.
