Abstract: A touchless harvester employing pulsed air to optimally remove a food product from its host is presented. The touchless harvester includes preferably at least one oscillating impeller housing fitted with an air plenum, a pulse generator and a nozzle to tangentially project pulsed air into a tree canopy or other harvest venue. The touchless harvester is fixedly mounted to a mobile platform to propel the touchless harvester through a harvest venue during operation. The touchless harvester is operated by controlling optimally three tunable variables, which produce optimal displacement conditions for a particular food product. The tunable variables control, respectively, the intensity, the frequency, and the duration that pulsed air is applied to a harvest venue. By tuning the intensity, frequency and duration of the projected air pulse, commensurate with a food product's resonant frequency, the food product experiences fatigue failure at its appendage, and maximum displacement from its host.
