Original WRA caption: Note: The markings on the blackboard, upper right, show the Japanese way of counting in fives to show number of buckets of beans processed. The bucket on the lower right contains soy beans which are soaked over night and then poured into this centrifugal "masher" which revolves at comparatively high speed. The white, crushed bean substance drops down into the container below in a white paste-like form.
