Development of pneumatic harvesting technology; Imuvaunutekniikan kehittaeminen

Abstract

The collecting capacity and time consuming of present pneumatic harvesters have been studied in this research on field conditions. The guidelines for future development of pneumatic harvesting method have also been presented. Operational efficiency measurements of pneumatic harvesters were carried out using seven different harvesters. The average of the hectare yield of the most efficient harvester was measured to be 17.2 t/ha and the capacity 7.2 kg/s. According to the measurements the yields were extremely low, the best yields being only 36 %, which means that 64 % of the milled layer remained on the field. Because it is possible to increase the collecting efficiency and decrease the power demand and dust emissions of a pneumatic harvester remarkably using activation of the milled layer, the target should be development of a pneumatic harvester equipped with activator of the milled layer. The pneumatic harvester should also be equipped with miller, so the drying energy supplied by the sun could be maximally utilized.
