Document Type and Number:
Japanese Patent JP3145393
Kind Code:
B2
Abstract:
The invention relates to a method for drying lengths of carrier material which have been printed with ink comprising an evaporable solvent. To maintain the concentration of the solvents evaporating from the printing ink, this concentration has to be determined. As known apparatuses for measuring the concentration are expensive, prone to faults and need regular calibration, the present invention provides a method for calculating that concentration. According to said method the concentration of the evaporated solvents in the gas mixture is determined by measurement of the temperature and flow rate of a mixture to be supplied to the burner (2), and by measurement of the temperature of the gas mixture heated by the burner (2) and by measurement of the flow rate of the fuel supplied to the burner (2). More precisely the concentration is determined by calculation of the increase in heat of the gas mixture in the burner (2), the amount of heat supplied by the burner (2), and in which from the difference thereof the burning heat of the solvents is determined, after which with the known burning value thereof the concentration is determined.
