Abstract:
A sprayer having at least one spray nozzle for directing a liquid spray toward an agricultural product, comprising:a tank for receiving a quantity of liquid and an additive in particulate form for mixture with the liquid;a pump having an inlet in flow communication with the tank and having an outlet for pumping the liquid mixture from the tank;means defining first and second flow paths for the liquid mixture pumped from the outlet, one such flow path leading to the spray nozzle whereby a spray of the liquid mixture is directed toward the agricultural product;the other such flow path leading to at least one other nozzle communicating with the tank and directing a stream of the pumped liquid mixture to impact a surface with force sufficient to pulverize particles of the additive entrained in the stream; andthe surface being located in flow communication with the tank so that the liquid mixture impacting the surface remains in the tank after impacting the surface,whereby a portion of the liquid mixture is pumped from the tank and recirculates through the other flow path including the pulverizing impact with the surface so as to reduce the amount of undissolved particulate additive in the liquid.
