METHOD AND APPARATUS FOR HEATING VOLUMES OF MEDIA IN A CLOSED RECEPTACLE BY MEANS OF AN ELECTROMAGNETIC RADIATION

摘要

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.

1. A method for heating volumes of media in a closed receptacle by an electromagnetic radiation, wherein a database is established prior to carrying out heating in that
in a step A at least one reference receptacle which is made of a known material, has a known volume and contains a known medium is irradiated in each instance by a first to nth electromagnetic radiation for a period of time, wherein the characteristics of the first to nth electromagnetic radiation are known, in a step B a number of measurement values of at least one measured quantity are collected at known measurement times over the duration of the irradiation and acquired as measurement sequences associated with the reference receptacle and are stored retrievably as reference measurement sequences, in a step C 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 are selected from the reference measurement sequences, in a step D an irradiation regime is derived in each instance from the selected reference measurement sequences and is stored so as to be associated with these selected reference measurement sequences, and wherein when heating is carried out in a step a the receptacle is irradiated for a known irradiation period by the electromagnetic radiation having characteristics which are known, and 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, is collected and is checked for the presence of a match with the values of reference measurement sequences stored in a database, thereafter in a step b when there is a match between the at least one measurement value and a value of a reference measurement sequence, an irradiation regime associated with the relevant reference measurement sequence is selected, and then in a step c heating of the receptacle is continued to a predetermined end point temperature Treq using the selected irradiation regime.
