Strength of the tank hopper is extremely critical to the life of the complete tank. For this reason, each hopper panel is precision fabricated from high strength commercial galvanized steel and designed for maximum support when assembled. Hoppers are available in a variety of slopes to match the correct tank size and required application. Both 45 and 40 degree hoppers are generally used with most dry whole grain products. The 45 degree hoppers are also often used for “wet holding.” A 60 degree hoppers are used for “wet holding” or other applications where a 60 degree is better suited.
