Estimating airflow for in-bin grain drying systems (1989)
Abstract
One of the most often asked questions about in-bin grain drying is 'How long will it take to dry the grain?' It is virtually impossible to answer this question unless you can satisfactorily estimate the airflow delivered by the drying fan. This guide will help estimate that airflow. It will also help you compare performance of two or more fans under your conditions. This guide can also be used to determine another important term, cubic feet per minute per bushel (cfm/bu). The cfm/bu level of your fan(s) determines how fast grain will be dried in your bin(s).
