Fan Selection for Grain Drying and Storage Videos

Part 1: Understanding Airflow Principles to Properly Select Grain Bin Fans

Part 1 of 2 from the "Fan Selection for Grain Drying and Storage" series from NDSU Extension. This video shows what static pressure is, how to measure it and how it pertains to proper grain drying. In the video the effect of correctly and incorrectly sized perforated floors, air velocity and grain depth on static pressure are effectively demonstrated as well as the effect of inadequate bin vents. Part 2: "Grain Drying and Storage Fan Characteristics" can be found at the following link:

Part 2: Grain Drying and Storage Fan Characteristics

Part 2 in the "Fan Selection for Grain Drying and Storage" series. In this video Dr. Ken Hellevang, shows and describes axial, centrifugal and in-line centrifugal fan operating characteristics for effective grain drying.

Fan Selection for Grain Drying and Storage - Parts 1 and 2.

Proper design of the air handling equipment in a grain drying system is necessary to successfully dry and store grain. Even a large fan may not provide the required airflow if the system is not sized correctly. In part 1 of this video, the basics of static pressure are demonstrated and explained how they affect grain drying. Part 2 shows examples of the 3 main types of grain bin fans and provides a discussion of their characteristics. The links for the individual sections of the video are provided below.
