Berry harvesting by pulsed air flow

Abstract

This paper presents a unique technical solution of berry fruit harvesting by accurately controlled pulsations of air flow. A special harvester, which induces strong turbulent fluctuations of atmospheric air from both sides of the plants, has been designed and tested in the past fifteen years. It is towed behind a tractor, but also equipped by own diesel engine that drive all hydraulic components and, indirectly, the fan, pulsating air flow control units, machine leveling system and fruit conveyer. The study is focused to operational parameters of the harvester, technical specification and design.
