PROBLEM TO BE SOLVED: To provide a method for steaming malt raw material, which causes no agglomeration and prevents the occurrence of sticking due to contact with dew condensation water in the case of using a rotary drum.SOLUTION: When a malt raw material K is steamed in a drum 1a, the malt raw material K is continuously or intermittently agitated while heating means heats the drum 1a so as to complete the steaming, preventing the occurrence of dew condensation water on the inner surface of the drum 1a. The heating means may include, for example, a double structure rotary drum body 1 for heating the wall surface of the drum 1a by feeding steam inside a jacket 2. Since no agglomeration of raw material occurs, uniform steaming can be achieved. Since no dew condensation water is attached to the inner surface of the drum, the occurrence of sticking due to contact with dew condensation water can be prevented. |
