Abstract
In a device or method to fix print images on a recording material, a printing fluid comprising a carrier fluid and chromophoric solid particles are applied to the recording material, the chromophoric solid particles being applied in a form of the print images to be fixed. Hot waste gas and infrared radiation are generated with aid of a porous burner. The infrared radiation is directed towards the recording material in a drying chamber such that the carrier fluid polymerizes or is vaporized, whereby a gaseous air/oil mixture arises in the drying chamber. The air/oil mixture is influenced with aid of the hot waste gas of the porous burner.
Claims16
A device to fix print images on a recording material, comprising:
- a drying chamber;
- the recording material moving through the drying chamber and on which is applied a printing fluid comprising carrier fluid and chromophoric solid particles, the chromophoric solid particles being applied in a form of the print images to be fixed;
- and
- a porous burner that generates hot waste gas and infrared radiation and which is arranged in the drying chamber so that the infrared radiation of the porous burner is directed towards the recording material such that the carrier fluid of the printing fluid polymerizes or vaporizes, a gaseous air/oil mixture arising in the drying chamber and that is influenced by the hot waste gas of the porous burner.
A method to fix print images on a recording material, comprising the steps of:
- applying a printing fluid comprising a carrier fluid and chromophoric solid particles to the recording material, the chromophoric solid particles being applied in a form of the print images to be fixed;
- generating hot waste gas and infrared radiation with aid of a porous burner in a drying chamber;
- directing the infrared radiation towards the recording material such that the carrier fluid polymerizes or is vaporized, whereby a gaseous air/oil mixture arises in the drying chamber;
- and
- influencing the air/oil mixture with aid of the hot waste gas of the porous burner.

- a porous burner that generates hot waste gas and infrared radiation and which is arranged in the drying chamber so that the infrared radiation of the porous burner is directed towards the recording material such that the carrier fluid of the printing fluid polymerizes or vaporizes, a gaseous air/oil mixture arising and being present in said drying chamber as a result of the polymerizing or vaporizing of the carrier fluid;
- and
- a thinning unit to thin the air/oil mixture in the drying chamber by introducing fresh air mixed with said waste gas or fresh air heated by said hot waste gas into said drying chamber.

- generating hot waste gas and infrared radiation with aid of a porous burner in a drying chamber;
- directing the infrared radiation towards the recording material such that the carrier fluid polymerizes or is vaporized, a gaseous air/oil mixture arising in the drying chamber based on the polymerizing or vaporizing of the carrier fluid;
- and
- thinning the air/oil mixture in the drying chamber by introducing fresh air mixed with the hot waste gas or fresh air heated by the hot waste gas into the drying chamber.
