Abstract

Consumption of wettable powders (WP) and water-soluble granules (WSG) have increased in last years in the pesticide market. Main problems faced with these kinds of pesticides are the requirement of continuous mixing due to sedimentation in sprayer tanks. To solve this problem, usage of hydraulic jet agitators in sprayer tanks have increased in last years. However, position of agitator in tank, mixing pressure and technical specifications of hydraulic jets are important for an effective agitation. In this study, we determined the agitation performances of a hydraulic jet in a 400 L sprayer tank by using one jet nozzle at 3 different jet nozzle sizes (orifice size: 1.0, 1.5 and 3.0 mm) and 3 different agitating pressures (3, 6 and 8 bar). Kaolin clay and Cooper oxide chloride were used as a tracer material for simulating WP and WSG solutions in the tank. And, International ISO 5682-2: 1997 (E) Standard has been used for sampling method in the tank level. To measure the rate of tracer material in the tank, turbimetric and drying method were used and results were comparted with reference solution concentrations to determinate of deviation rates. As a result, deviation rates of all agitation configuration used in this research were higher than the defined acceptable limits in ISO 5682-2: 1997 (E) at all measurements in the sprayer tank.
