example 1
[0054] Ecolab Inc.'s OptiPro dispenser was tested using Ecolab Inc.'s OptiPro Enzyme product. During the test, the concentration in the reservoir of the dispenser increased with increasing time between cycles of the dispenser. Also, as the amount of OptiProEnzyme product removed from the reservoir per cycle decreases, the concentration in the reservoir increases. It was determined that both of these variables can be expressed as the diluent injection on time and injection off time.

[0056] Design of Experiments ("DOE") was performed to investigate the effect of spray on time and spray off (delay) time on the concentration of the concentrated solution in the reservoirs of Ecolab Inc.'s ASEPTI-Solid and OptiPro dispensers. Experiments were performed using a conductivity analyzer and data logger to measure the conductivity of the concentrated solution and convert the conductivity to percent weight of concentration. The experiment was run continuously to speed up the test, which means that the injection cycle continued to run until the block of solid product was exhausted. In normal operation, the spray cycle runs only until, the dispenser's reservoir is at full level, and does not run again until the machine (in this case, a surgical instrument washing machine) draws concentrated solution again, which may be from Any time ranging from immediate to several days.
[0057] Figure 5 Indicates DOE. The spray on times used were 0.5, 0.7 and 1.0 seconds. The j...

[0062] Such as Figure 8 As shown, the graph titled "Pulse Controlled Injection vs. Uncontrolled Injection" represents the reservoir concentration of the dispensed fraction of solid product in the reservoir by weight of solution used for both pulsed controlled injection and non-controlled injection. .
[0063] Ecolab Inc.'s OptiPro dispenser was tested using Ecolab Inc.'s OptiPro Enzyme product. In the experiments, a solid product of the same chemical formula was dispensed with a 0.7 second pulsating water jet on and a 20 second off or continuous non-pulsating water jet during the product dispensing process. Experiments were performed using a conductivity analyzer and data logger to measure the conductivity of the concentrated solution and convert the conductivity to percent weight of concentration. Such as Figure 8 As shown, the "pulse controlled spray" produced a reservoir concentration approximately 1.25% (by weight) higher than the reservoir concentration produced when...
