Abstract:
... The aerial electrostatic spraying system patented by the USDA-ARS is a unique aerial application system which inductively charges spray particles for the purpose of increasing deposition and efficacy. While this system has many potential benefits, very little is known about how changes in airspeed or nozzle orifice size affect the spray droplet spectrum of charged spray. This study quantified thes ...

Abstract:
... Peanut (Arachis hypogaea L.) drying is an essential task preceding the grading process. Kernel moisture is one of five parameters used to establish the grade for a specific lot of peanuts, and it is imperative that peanuts be dried to a kernel moisture content <10.5% wet basis for grading and storage purposes. Today's peanut drying processes utilize decision support software based on modeling and ...
