Abstract
The invention relates to a method for heating volumes of media (11) in a closed receptacle (10) by means of an electromagnetic radiation (2), wherein a database (4) is prepared based on measurements of reference receptacles, and irradiation regimes are selected or generated using the database (4) and used for heating the media (11). The invention further relates to an apparatus for carrying out the method.
Claims14
A method for heating volumes of media in a closed receptacle by electromagnetic radiation, wherein the method comprises, prior to carrying out heating, establishing a database by proceeding as follows:
- irradiating in each instance at least one reference receptacle which is made of a known material, has a known volume and contains a known medium by a first to nth electromagnetic radiation for a period of time, the characteristics of the first to nth electromagnetic radiation being known,
- collecting a number of measurement values of at least one measured quantity at known measurement times over a duration of the irradiation and acquiring the measurement values as measurement sequences associated with the reference receptacle and storing them retrievably as reference measurement sequences,
- selecting from the collected reference measurement sequences those reference measurement sequences which were created within a selected irradiation period during which a selected amount of energy was coupled into the reference receptacle,
- deriving an irradiation regime in each instance from the selected reference measurement sequences and storing the irradiation regime so as to be associated with the selected reference measurement sequences;
- and wherein the method further comprises carrying out heating by proceeding as follows:
- irradiating the receptacle for a known irradiation period by the electromagnetic radiation having characteristics which are known, and collecting at least one measurement value of a measured quantity, which measurement value is associated with the receptacle and is associated with a measurement time within the irradiation period, and checking the measurement value for the presence of a match with values of reference measurement sequences stored in a database, thereafter
- when there is a match between the at least one measurement value and a value of a reference measurement sequence, selecting an irradiation regime associated with the relevant reference measurement sequence, and then
- continuing the heating of the receptacle to a predetermined end point temperature Treq using the selected irradiation regime.
