1. General Design Criteria
Note
Continuous Mixed-Flow Grain Dryer design is based on load factors. If you wish to add more
sections to your dryer in the future, please let NECO know when you place your order so it will
be designed to fit to your expanding needs.
Tier Information
• A tier is a set of parts that make up ONE layer of the dryer (also called body section).
• The top four tiers on all dryers are made up of 18 gauge material.
• The tiers below the 18 gauge tiers will be made of heavier materials, based on the required strength of that
dryer configuration.
Body Section Information
• An assembled dryer section may be made up of:
– 3 to 7 tiers
– a blower
– a burner
• The lowest body section is attached to the dryer frame and includes the entrance door.
