Stirring Cuts Low Temperature Drying Costs
- Stirring Speeds Drying!
- You get 33% more aiflow when a Sukup Fastir Stirring Machine is used in wet grain
with a powered grain spreader, according to tests conducted by Iowa State University.*
- Stirring loosens the grain, allowing the fan to move more air through the grain more
- More airflow means faster drying!
- Stirring Reduces The Chance of Spoilage!
- Drying without stirring can be a race to get the top layer of grain in the bin dried
before it spoils. In favorable weather it can be risky. If the weather is bad, it can be
- Stirring helps prevent top layers from spoiling by blending the entire bin of grain -
all the grain dries evenly, safely.
- Stirring Stops Overdrying!
- Without stirring, the bottom of the bin becomes overdried before the top layers reach
safe storage levels.
- Overdrying to 11% average moisture content will cost you $0.20/bu! This is a common
occurrence when drying without a stirring machine.
- With a stirring machine, the grain is thoroughly mixed to less than 1% moisture
variation throughout the bin until all the grain is evenly dried to the moisture content
desired. No overdrying!
