Abstract
A method for monitoring the function of a pasteurization installation, and to a pasteurization installation having a device for monitoring the function, providing a quick and simple way of detecting malfunctions. For this purpose, a theoretical expected value of the resource consumption, in particular of the energy and/or water consumption, is calculated, the actual value is determined and from a deviation between the expected value and the actual value a malfunction of the pasteurization installation is concluded.
Claims13
A method of monitoring the function of a pasteurization installation providing treatment for products and having at least two zones cooled by supplying fresh water from a fresh water supply via a fresh water conduit, comprising:
- calculating a theoretical expected value of an energy and a water consumption, determining an actual value of the energy and the water consumption, and concluding, from a deviation between the theoretical expected value and the actual value, a malfunction of the pasteurization installation,
- wherein the theoretical expected value of the energy consumption is calculated via an energy take-up of each of the products and at least one of an energy loss to an environment of the pasteurization installation or an energy loss between the at least two zones of the pasteurization installation,
- wherein the actual value of the energy consumption is determined via a volume flow rate through and a temperature difference across a main heat exchanger system, the main heat exchanger system configured to transfer heat to each of the at least two zones,
- and
- wherein the theoretical expected value of the water consumption is calculated based on differences between temperatures of the at least two zones to be cooled and a temperature of the fresh water multiplied with a heat capacity of the fresh water, and
- wherein the actual value of the water consumption is determined by measuring a flow rate of the fresh water through the fresh water conduit, wherein the fresh water through the fresh water conduit is supplied to each of the at least two zones.
A method of monitoring a pasteurization installation in a main heat exchanger system providing treatment for products and having at least two zones to be cooled by supplying fresh water from a fresh water supply via a fresh water conduit, comprising:
- calculating a theoretical expected value of an energy consumption based on a product temperature and a predetermined heat transfer parameter;
- calculating a theoretical expected value of a water consumption based on temperatures of the at least two zones to be cooled and a temperature of the fresh water;
- determining an actual value of the energy consumption based on a volume flow rate through the main heat exchanger system and a temperature difference across the main heat exchanger system, the main heat exchanger system configured to transfer heat to each of the at least two zones;
- determining an actual value of the water consumption based on a flow rate of the fresh water through the fresh water conduit measured by a flow meter in the fresh water conduit, wherein the fresh water through the fresh water conduit is supplied to each of the at least two zones;
- calculating a first deviation between the theoretical expected value of the energy consumption and the actual value of the energy consumption;
- calculating a second deviation between the theoretical expected value of the water consumption and the actual value of the water consumption;
- and
- concluding, based on at least one of the first deviation and the second deviation, a malfunction of the pasteurization installation.
