Abstract

The present disclosure relates to a process and a system for assessing the performance of cleaning operations by utilizing an automatic read out routine for test strips subjected to a cleaning operation. Furthermore, the present disclosure relates to a computer program product capable of performing the process.

Claims (35)

1. A system comprising:

a cleaning assessment application executable on a user computing device and configured to guide a user through a test strip image capture procedure on the user computing device; and

a computing device comprising one or more processors configured to:

evaluate an image of a test strip captured during the test strip image capture procedure after the test strip has been exposed to a cleaning process;

generate an assessment of the performance of the cleaning process based on the evaluation, the test strip including a carrier and an indicator operable to change as a function of the cleaning process; and

generate, for display on the user computing device, the assessment of the performance of the cleaning process.

2. The system of claim 1 , wherein the computing device is located remotely with respect to the user computing device.

3. The system of claim 1 , wherein the cleaning assessment application is further configured to display steps of the test strip image capture procedure on a display of the user computing device.

4. The system of claim 1 , wherein to evaluate the image of the test strip the computing device is further configured to determine a ratio of black and white pixels in the image of the test strip.

5. The system of claim 1 , wherein the assessment of the performance of the cleaning process includes a quantitative value indicative of the performance of the cleaning process.

6. The system of claim 1 , wherein the assessment of the performance of the cleaning process includes one of a pass or a fail.

7. The system of claim 1 , wherein the computing device is further configured to select an action plan based on the assessment of the performance of the cleaning process.

8. The system of claim 7 , wherein the action plan includes one or more of instructions to increase or lower a detergent concentration, raise or lower a temperature, raise or lower a process time, use a different detergent, control or change a water quality, and control or change a water hardness.

9. The system of claim 1 , wherein the cleaning assessment application is further configured to display the image of the test strip on a display of the user computing device.

10. The system of claim 1 , wherein the indicator of the test strip includes one or more of:

a chemical indicator operable to change color as a function of the cleaning process; and

a representative soil operable to be physically removed as a function of the cleaning process.

11. The system of claim 1 , wherein to evaluate the image of the test strip the computing device is further configured to determine an amount of color change of a chemical indicator on the test strip as a result of the cleaning process.

12. The system of claim 1 , wherein to evaluate the image of the test strip the computing device is further configured to determine an amount of physical removal of a representative soil on the test strip as a result of the cleaning process.

13. A method comprising:

generating, for display on a user computing device, steps of a test strip image capture procedure;

evaluating, by one or more processors, an image the test strip captured during the image capture procedure after the test strip has been exposed to a cleaning process, the test strip including an indicator operable to change as a function of the cleaning process; and

generating, by the one or more processors for display on the user computing device, an assessment of the performance of the cleaning process based on the evaluation.

14. The method of claim 13 , wherein the computing device is located remotely with respect to the user computing device.

15. The method of claim 13 , wherein evaluating the image of the test strip further comprises determining a ratio of black and white pixels in the image of the test strip.

16. The method of claim 13 , wherein the assessment of the performance of the cleaning process includes a quantitative value indicative of the performance of the cleaning process.

17. The method of claim 13 , wherein the assessment of the performance of the cleaning process includes one of a pass or a fail.

18. The method of claim 13 , further comprising selecting, by the one or more processors, an action plan based on the assessment of the performance of the cleaning process.

19. The method of claim 13 , wherein evaluating the image of the indicator area of the test further comprises at least one of:

determining an amount of color change of a chemical indicator on the test strip as a result of the cleaning process; and

determining an amount of physical removal of a representative soil on the test strip as a result of the cleaning process.

20. A non-transitory computer-readable storage medium comprising instructions that when executed by one or more processors cause the one or more processors to:

generate, for display on a user computing device, steps of a test strip image capture procedure;

evaluate, by one or more processors, an image the test strip captured during the image capture procedure after the test strip has been exposed to a cleaning process, the test strip including an indicator operable to change as a function of the cleaning process; and

generate, by the one or more processors for display on the user computing device, an assessment of the performance of the cleaning process based on the evaluation.
