Automatic Monitoring and Cutoff of Peanut Dryers

Authors: ,


A method for automatic cutoff of full-scale peanut dryers when peanuts approach a prescribed moisture content without periodic moisture sampling is described. Final weight is mathematically predicted from initial weight and moisture content. Peanut weight loss is monitored and dryer operation subsequently controlled through electronics. Six of 8 drying wagon loads of peanuts dried with the method were dried to a satisfactory moisture content at grading. Additional drying was required on 2 loads. Test results indicate that the method will require less labor, provide better moisture control, and reduce the danger of overdrying compared to conventional methods.
