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.
Energy Efficient Grain Drying
Ken Hellevang, Agricultural Engineering Specialist with the NDSU Extension Service and Professor in the Agricultural and Biosystems Engineering Department describes the different types of grain dryers, energy efficiency features of dryers, recommended dryer management to improve energy efficiency and the typical energy consumption of the dryers.
Grain Dryer Energy Audit
Ken Hellevang, Agricultural Engineering Specialist with the NDSU Extension Service and Professor in the Agricultural and Biosystems Engineering Department demonstrates the procedure of conducting a grain dryer energy audit including the information required, calculations to determine the amount of water removed, energy required, and the energy consumption. Examples are included for different types of dryers and grain.
