Inspection of the equipment used in drying certified peanuts to see that it is
operated according to the following guidelines is required. The thermostat and
humidistat used on drying certified peanut seed must be set according to ambient
air conditions. If a humidistat is not available or operative, the maximum
temperature setting should be 80°
F. Even though a humidistat is utilized, the temperature should never exceed 9O°
F. during the drying process. Natural air should be used in the day unless the
relative humidity exceeds 65%, in which case supplemental heat may be necessary.
If supplemental heat is needed, never use over l0°
to l5° F temperature rise. The airflow rate should be 10—15
cubic feet per minute per cubic foot of peanuts. The depth for peanuts in the
dryer should be limited to about four feet for 30% moisture peanuts; for higher
moisture content, the depth should be reduced.
