Abstract
A system for process monitoring of the treatment of media, in particular a HACCP-compliant system for the preservation of foods. In order to ensure and standardize successful treatment, system comprises an electroporator for treating a medium with a pulsed electric field, at least one measuring device for determining a change of a condition parameter of the medium caused by the treatment with the pulsed electric field, and an evaluation device for comparing the determined change of the condition parameter to a predetermined change target value and for outputting a warning signal once the difference between the determined change and the predetermined change target value exceeds a limit value.
Claims20
A system (1) for process monitoring of the treatment of media (3), including an HACCP-compliant system (1) for the preservation of foods, comprising an electroporator (2) for treating a medium (3) with a pulsed electric field, at least one measuring device (4) for determining a temperature increase of said medium (3) caused by the treatment with said pulsed electric field, where said measuring device (4) comprises at least one inlet thermometer (23) for determining the temperature of said medium before it enters said electroporator (2) and at least one outlet thermometer (24) for determining the temperature of the medium after it exits said electroporator (2), and an evaluation device (6) for comparing the determined temperature increase to a predetermined temperature increase and for outputting a warning signal once the difference between the determined temperature increase and the predetermined temperature increase exceeds a limit value.
A system (1) for process monitoring of the treatment of media (3), including an HACCP-compliant system (1) for the preservation of gods, comprising
- a conveying line (6) and a drive (7) for transporting said medium (3),
- an electroporator (2) for treating a medium (3) with a pulsed electric field,
- a speed sensor for determining conveying speed of said medium (3) transported on said conveying line (6) through said electroporator (2),
- at least one Measuring device (4) for determining a temperature increase of said medium (3) caused by the treatment with said pulsed electric field, where said measuring device (4) comprises at least one inlet thermometer (23) for determining the temperature of said medium before it enters said electroporator (2) and at least one outlet thermometer (24) for determining the temperature of the medium after t exits said electroporator (2),
- a control unit (15) for adjusting a conveying speed of said medium (3) or at least one operating parameter of said electroporator (2), and
- an evaluation device (5) for comparing the determined temperature increase to a predetermined temperature increase and for outputting a warning signal once the difference between the determined temperature increase and the predetermined temperature increase exceeds a limit value, wherein the control unit is configured to adjust a parameter of the electroporation in dependence of the determined conveying speed.
