Embodiment Construction

[0024] figure 1 The structure of the device according to the invention is shown, which is used to carry out the method according to the invention. A multi-sensor arrangement is shown here with symbol 1, in which a plurality of individual sensors M are provided 1 , M 2 ,...,M n . The multisensor device 1 is made of noble metal, heat-resistant and / or acid-resistant plastic or other suitable materials.

[0025] Single sensor M for multi-sensor installations 1 to M n It is connected to the data receiver 2 via a line (not further shown). As a result, the multi-sensor device 1 can be installed at an arbitrary location regardless of the position of the data receiver 2 . Data receiver 2 for sensor M of multi-sensor device 1 1 to M n , Data transmission between the measuring transformer 3 connected behind and the control device 6 . Through the control device 6, n sensors M 1 to M n The operating parameters are regulated. These parameters include operating temperature, supp...

Abstract

The application presents and describes a method and an apparatus for measuring the killing effectiveness of a disinfectant for micro organisms and the spores thereof with a sensor system which has at least two sensors, wherein the at least two sensors are in contact with the disinfectant and the measured signals are collected by a computation unit which is connected to the sensor system. In order to reliably determine the sterilization effect of arbitrary disinfecting processes and disinfectants, provision is made for a validated germ reduction test to be performed during a signal capture in order to determine the germ reduction rate and for the measured signals to be put into a particular ratio to one another and for this to be used to calculate, for each state of the disinfectant, a particular pattern which is used as a basis for a reproducible ratio for signal data and sterilization effect. In this case, the sensor system has a plurality of sensors (M1, M2,..., Mn) which are combined to form a multisensor unit (1) which is connected to a computation unit (4). FIGURE 1 is intended for the abstract.

Description

technical field [0001] The invention relates to a method for measuring the sterilizing effect of a sterilizing agent against microorganisms and their spores (durable form) by means of a sensor system having at least two sensors, wherein the at least two sensors are connected to the sterilizing agent The bacterial agent comes into contact and the measurement signal is collected by an arithmetic unit connected to the sensor system. Background technique [0002] For the sterilization of consumer goods, e.g. beverages, the canned product is ensured by sterilizing the packaging container and (if necessary) the product separately, filling the cans into a sterilized and cleaned container, and then sealing the container Freshness for the expected time. For this purpose, the container and (if applicable) the pouring element used are brought into contact with a conventional steam-like disinfectant, so that microorganisms in or on it are reliably killed. Hydrogen peroxide (H 2 o 2 ...
