"A direct injection system (DIS) for pesticide injection at all nozzles was set up in order to ascertain its ability to be cleaned. Under laboratory conditions, the system was contaminated with a safe-to-use salty polyvinylpyrrolidonewater solution as a test pesticide and then cleaned in two steps: (1) reclaiming the test pesticide by pushing it back into the pesticide tank using pressurized air (pre-cleaning) and (2) rinsing the contaminated part of the hydraulic system with water. Tests on a 3 m wide test bench included gravimetric and conductivity measurements to determine the amount of residues in the test section and test pesticide concentrations in the rinsing water. Mechanical action inside the test section was varied by (1) increasing the air pressure for pre-cleaning, (2) increasing the rinsing water pressure, and (3) employing pulsed water-air flow. Initial test pesticide concentrations in the rinsing water could be as high as 25%, which is more than in common spray mixes and requires fur" . .
