A device for drying and sintering metal-containing ink on a substrate enables homogeneous irradiation of the substrate, has compact construction, and is simple and economical to produce. Optical infrared radiators have a cylindrical radiator tube and a longitudinal axis, and emit radiation having an IR-B radiation component of at least 30% and an IR-C radiation component of at least 5% of total radiator output power. The radiators are arranged in a module with their longitudinal axes running parallel to each other and transverse to the transport direction. They thereby irradiate on the surface of the substrate an irradiation field, which is divided into a drying zone and a sintering zone arranged downstream of the drying zone in the transport direction. The drying zone is exposed to at least 15% less average irradiation density than the sintering zone along a center axis running in the transport direction.

Device for drying and sintering metal-containing ink on a substrate

A device is provided which ensures uniform irradiation of plants with infrared radiation along with ultraviolet and/or visible radiation and requires a small number of infrared emitters relative to the cultivation area. The infrared emitters are designed for temperatures of 800&#xb0; C. to 1800&#xb0; C. Each has a cylindrical emitter tube having a length of 50 mm to 500 mm. The emitter tubes extend parallel to one another in an emitter zone located above the culture plane. The infrared emitter occupation density relative to the area of the culture plane is between 0.2 mand 1.0 m. Irradiation regions of adjacent infrared emitters on the culture plane overlap such that average irradiance on the culture plane is between 10 watt/mand 100 watt/mwith a variation range of a maximum of 50%. A reflector facing a structural space is assigned to a top side of the emitter tube.
