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.

CRITERIA

6 7713402 R0
Dryer Model Number
D Series Model Numbers
The dryer model number provides information on the dryer length and capacity.
• The two digits after “D" are the dryer length.
• Multiply the remaining digits by 10 to determine the approximate bushel capacity for corn. In this example:
40 x 10 = 400 bushels
Example: D 16 60
•16 indicates this model is a 16 foot long dryer
•60 indicates this model has a capacity of 60 x 10 = 600 bushels
Using the same process, a model D32500 would be a 32 foot long dryer with an approximate capacity of 5,000
bushels.
K Series Model Number
The three digits after “K” indicate the nominal storage capacity. For example, a K600 holds approximately 600
bushels of grain.
