Definitions

  • the invention is about an infrared dryer system for drying a substrate moved in a transport direction through a process space, comprising an infrared dryer module which, viewed in the substrate transport direction, has a sequence of the following components: a front air exchanger unit, one with several in parallel Irradiation room equipped with mutually arranged infrared radiators, and a rear air exchanger unit.
  • Such air dryer modules and drying processes are used, for example, for drying water-based dispersions, inks, paints, varnishes, adhesives or other solvent-containing layers on substrates or for drying moist material sheets made of fleece and other textile materials are used.
  • Infrared dryer systems are used in particular for drying printed products such as paper and cardboard and products made from them.
  • Offset printing machines lithographic printing machines, rotary printing machines or flexographic printing machines are used to print sheet-shaped or web-shaped printing materials made of paper, cardboard, foil or cardboard with printing inks.
  • Typical ingredients of printing inks and inks are oils, resins, water and binders.
  • drying is required, which can be based on both physical and chemical drying processes. Physical drying processes include the evaporation of solvents (especially water) and their diffusion into the printing material. Chemical drying refers to the oxidation or polymerization of printing ink ingredients.
  • infrared dryer systems have other functional modules such as cooling, supply air and exhaust air, which are linked and regulated in various forms in an air management system.
  • this describes DE 10 2010 046 756 A1 a dryer module and a dryer system composed of several dryer modules for printing machines for printing sheet or roll material.
  • the dryer system consists of several infrared dryer modules arranged transversely to the transport direction, each of which has an elongated infrared radiator aimed at the printing material to be dried, the longitudinal axis of which runs perpendicular to the transport direction of the printing material.
  • An adjustable ventilation system creates an air flow that acts on the infrared radiator and the printing material.
  • the infrared radiator is arranged within a process space for the printing material.
  • the supply air is fed to a supply air collection room and heated there by a heating device.
  • the air heated by the infrared heater is removed by means of a fan, added to the heated supply air and the infrared heater is thereby cooled.

  • the degree of inclination of the slot nozzles can be changed using a motor.
  • the moisture-laden supply air is removed from the process room as exhaust air via an intake duct and partly fed to a heat exchanger, and another part is added to the supply air collection room.
  • the process gas is heated using a specially designed heating device.
  • the heated process gas exits via the slot nozzles in the direction of the printing material as a heated air flow and acts on the printing material to be dried locally and otherwise in a more or less undefined manner until it is sucked out again elsewhere as moisture-laden air.
  • the effectiveness of the drying air in terms of moisture removal from the substrate surface is therefore not exactly reproducible.
  • the CA 2 748 263 C describes a method and a device for drying using heated air flow and ultrasound.
  • the ultrasonic transducers used for this generate ultrasonic waves with a power level in the range of 120 to 190 dB at the interface of the material to be dried and thus contribute to the breakdown of a diffusion boundary layer.

  • Both the gas intake opening and the gas exhaust opening are angled so that they form an angle of 45° with the vertical center line of the LED lamp holder.
  • the DE 10 2016 112 122 A1 shows a drying device for a material web moving in the transport direction, with a pressure chamber which is closed at the bottom by a plate, with several openings being provided in the plate for the supply of hot air to the material web.
  • a special feature of the hot air supply is that the axes of the supply air openings are inclined against the direction of movement of the material web.

  • the supply air flow is not diffuse, but has a main direction of propagation in which, depending on the air throughput and flow speed, it penetrates the substrate surface and hits it at a preset angle, where it has a drying effect on the coated substrate.
  • Action here means that the supply air flow dries the substrate, for example by absorbing solvents from the surface layer into the gas phase.
