Performance Evaluation of Tractor Mounted Axial Flow Mist Blower Sprayer

The performance evaluation between existing blower B, C and developed blower A was conducted at Pimpalgaon (Basawant) Dist - Nasik. blower A gave more velocity, discharge at 2260 rpm. Blower efficiency was maximum at 2260 rpm. Corresponding values were 31.62 m/sec, 1.79 m3/sec and efficiency 22.75 per cent respectively, whereas power required to run the blower was 7.32 kW for which 18 hp tractor can be used to operate it in the field. This blower is suitable for spraying grape and pomegranate crop. The maximum blower efficiency was observed in developed blower ‘A’ compared to blower ‘B’ 22.58 per cent and ‘C’ 17.65 per cent. Laboratory studies revealed that the blower ‘A’ having low efficiency 22.75% leading to develop the blower with more efficiency. Field performance studies of developed blower ‘A’ indicated that proper spray deposition and penetration could be obtained at travel speed of 3 kmph and system pressure of 15 bars. The laboratory studies revealed that blower of type A is suitable for grape vineyards and pomegranate orchard. Blower A should be operated at rotational speed of 2260 rpm at system pressure of 15 N/m2 with tractor forward speed of 3kmph for both crops.
