  • the invention relates to a device for generating process heat for a packaging device.
  • EP 1 705 242 describes the use of solar collectors for covering at least part of the heat energy consumption of a brewery plant, in particular for mashing, refining and / or wort boiling, but also for cleaning the plant or for operating a sorptive refrigeration plant.
  • the plant is operated with water as a heat transfer medium, which also serves as process water and is stored in a hot water heat storage. With this system, however, flow temperatures of up to 180 degrees Celsius are possible.
  • Packaging devices in particular in the form of the known shrinking devices, but have so far mostly electrically or occasionally heated with natural gas.
  • packaging devices in the form of shrinking devices For example, DE 35 16 609, DE 35 43 943, EP 1 288 129 or EP 678452 can be seen.
  • packaging plants for example when heating the air in shrinking equipment but must be operated at a much higher temperature than when heating process water or for heating purposes, and it is a stronger control of the temperature necessary, which so far when using no or limited controllable energy sources, as is the case with heat generation in solar or incineration plants, was considered impracticable.
  • the invention is therefore based on the object to expand the scope of alternative energy produced.
  • alternative energies such as, for example, solar energy or combustion energy from renewable raw materials or the like, are suitable for generating process heat for a packaging device.
  • a particularly preferred field of application for the device according to the invention is the generation of heat for a Schrumpfanläge.
  • the range of application is increased by the use of a high-temperature heat accumulator.
  • phase change material is preferably used, which can be selectively selected according to the temperature to be provided.
  • a metal is preferably used, with bismuth being particularly suitable for shrinking plants.
  • salts whose melting point is in the appropriate temperature range, for example crystalline sodium hydroxide.
  • a heat transfer medium is preferably used, which differs from the process medium.
  • the heat transfer medium is preferably a heat transfer oil.
  • pressurized water is also considered.
  • a source of energy is preferably a solar system containing commercially available solar panels.
  • a parabolic collector is particularly suitable, which can reach the necessary temperatures, but also for example by
  • Vacuum tube collectors can be replaced or, for a two-stage operation, a vacuum tube collector can be followed.
  • Collectors with heliostat mirrors also allow a high temperature level.
  • the energy source may further contain a combustion system, especially for renewable materials, however, which can also be used as a single source of energy and is then preferably coupled to the described high-temperature heat storage.
  • FIG. 1 shows a schematic representation of a device 1 for generating process heat.
  • the device 1 for generating process heat for a packaging device 2 in particular a Schrumpfanläge designed.
  • the Schrumpfanläge 2 is designed as a hot air continuous furnace (so-called. Shrink tunnel) through which objects, such as bottles, cans, boxes, loaded pallets or the like. Continuously move, the individually or in groups in a plastic shrink film or welded shrink labels should be provided.
  • Shrink tunnel hot air continuous furnace

  • the Schrumpfanläge works preferably with air nozzles through which heated air is blown against the shrink film.
  • the invention is also applicable to other packaging devices, working continuously or discontinuously, where heat is needed for a packaging process.
  • the heat required for packaging is supplied by an energy source 3, which provides its energy not limited or (limited) (not fast) controllable.
  • the power source 3 includes a solar system 4, which is equipped with conventional types of solar panels.
  • the solar system 4 operates in two stages, ie it contains at least one flat or (preferably) vacuum tube collector 4a may be part of a heating or domestic water heating device, for example, already exists or installed together with the device 1 ,
  • the solar system 4 further includes a collector 4b capable of supplying a higher temperature than the collectors 4a.
  • the collector 4b a parabolic trough collector.
  • the solar system 4 is used for direct or indirect (depending on the type of collector) heating a heat transfer medium, in particular a high-temperature heat transfer oil or pressurized water.
  • the heat transfer medium flows via a line 5 of the solar system, preferably via a pump Pl, in a high-temperature heat storage 7. Since experience shows that only part of the rated power is needed in the daily average, the heat storage 7 should store the excess heat for later retrieval.
  • the high-temperature heat storage 7 should be able to provide a temperature above 185 ° C, preferably above 200 ° C, about 300 ° C and most preferably in the range of 250 to 350 ° C, ie to provide a flow temperature that is sufficient to operate the packaging device used, for example, the shrinking plant 2.
  • the flow temperature must be adjusted to the conditions of the device 1 that the air at the outlet of the air nozzles has a temperature of 180 to 250 ° C, wherein the packaging film and / or the shrink label within a time window of nine is brought to a shrinking and softening temperature between 80 and 100 degrees Celsius to twelve seconds, so that the shrink film lays tightly around the objects to be packaged and possibly existing overlapping areas of the film are welded.

  • the heat accumulator 7 is heated by the heat transfer medium, i. the heat transfer oil, which is guided by the line 5 in a queue 6 through the heat accumulator 7, melted and gives its consumed during melting energy during solidification again. Since the heat transfer medium has no direct contact with the phase change material, the system is therefore closed, in principle, toxic phase materials can be used.
