Muro room (malted rice making room)

Abstract

A muro room (malted rice making room) is provided, which includes a room having a ceiling. The muro room includes a longer air shaft provided through the ceiling to exhaust hotter air out of the room, wherein the longer air shaft has height A. The muro room also includes a shorter air shaft provided through the ceiling to allow cooler air to enter the room, wherein the shorter air shaft has height B which is less than A. A distance between the longer air shaft and the shorter air shaft is greater than A, to facilitate natural ventilation in and out of the muro room during the rice fermentation process.
