Abstract

A process for food storage in refrigerators, freezers and the like involves evacuation of air and then operating a UV lamp installed in the refrigerator, etc..

Description

Dieses Verfahren ist zur Konservierung und Speicherung von Nahrungsmitteln, auch für Kühlschränke oder Kühlräume, in Schiffen und transportbare Kühlkontainer (z. B. auf Schienen), zu verwenden.This process is for food preservation and storage, too for refrigerators or cold rooms, in ships and transportable refrigerated containers (e.g. on rails).

Dies geschieht durch Sterilisation der Nahrungsmitteln mit Hilfe von ultravioletter Strahlung, die aus Lampen in den Kühlschränken, resultiert.This is done by sterilizing the food with the help of ultraviolet Radiation resulting from lamps in the refrigerators.

Diese Strahlung tötet Bakterien ab, die sich auf Nahrungsmitteln befinden, in der Luft, oder selbst in diesen Kühlschränken.This radiation kills bacteria that are on food in the Air, or even in those fridges.

Zuerst muß jedoch die Luft entleert werden, die sich im Kühlschrank befindet, damit der Sauerstoff durch die Strahlung nicht in Ozongas (O₃) verwandelt wird.First, however, the air that is in the refrigerator must be emptied the oxygen is not converted into ozone gas (O₃) by the radiation.

Wir bedenken dabei, daß Vakuumbedingungen Bakterien abtöten können, die aerob leben, oder kleine Insekten, die sich im Kühlschrank befinden.We keep in mind that vacuum conditions can kill bacteria that are aerobic, or small insects that are in the fridge.

Verteilung der ultravioletten Lampen im KühlschrankDistribution of the ultraviolet lamps in the refrigerator

Die Lampen können auf einer Drehscheibe innerhalb des Kühlschrankes an den Wänden oder auf der Decke angebracht werden (wenn die Lampen feststehend, dann parallel angeordnet).The lamps can be placed on a turntable inside the fridge on the walls or mounted on the ceiling (if the lamps are fixed, then parallel arranged).

Die Anzahl der ultravioletten (UV) Lampen hängt von der Größe des Kühlschrankes ab. In kleinen Kühlschränken reicht eine Lampe (befestigt oder beweglich) aus.The number of ultraviolet (UV) lamps depends on the size of the refrigerator. In small refrigerators, one lamp (fixed or movable) is sufficient.

In größeren Kühlschränken jedoch, hängt die Anzahl von der Größe des Kühlschrankes ab. In larger refrigerators, however, the number depends on the size of the refrigerator.  

Die Art der Sterilisation wie in der ZeichnungThe type of sterilization as in the drawing

  • 1. H₁ (Hahn 1) wird zugedreht oder ausgeschaltet, der normalerweise Luft rein­ läßt.1. H₁ (tap 1 ) is turned off or off, which normally lets air in.
  • 2. H₂ wird aufgedreht, der die Luft aus dem Kühlschrank entweichen läßt.2. H₂ is turned on, which allows the air to escape from the refrigerator.
  • 3. Verwendung des Kompressors oder einer Vakuumpumpe, um die Luft aus dem Inneren des Kühlschranks entweichen zu lassen, bis das der Luftdruck 1/10 des Atmo­ sphärendrucks von außen (außerhalb des Kühlschranks) beträgt.3. Use the compressor or a vacuum pump to blow the air from inside of the refrigerator until the air pressure is 1/10 of the atm spherical pressure from outside (outside the refrigerator).
  • Eine Vakuumbedingung reicht für eine schadenfreie (aerob bedingte Bakterien) Konservierung, speziell für Kartoffeln, Zwiebeln, Knoblauch, Zucchinis und auch für Obst, wie Äpfeln aus.A vacuum condition is sufficient for a damage-free (aerobic bacteria) Preservation, especially for potatoes, onions, garlic, zucchinis and also for fruit, like apples.
  • 4. Durch den Einsatz von UV-Lampen kann ein größeres Spektrum von Bakterien oder auch Viren ausgeschaltet werden. Der Einsatz von UV-Lampen ist nur für eine bestimmte Zeit bestimmt. Dann werden sie ausgeschaltet. 4. Through the use of UV lamps, a wider range of bacteria or viruses can also be switched off. The use of UV lamps is only for one certain time determined. Then they are turned off.  
  • 5. Sollten nun Nahrungsmittel ein- oder ausgeführt werden aus dem Kühlschrank, müssen zuerst die UV-Lampen ausgeschaltet werden. Danach wird Hahn 1 (H₁) geöffnet, der Luft hineinläßt, um den Atmosphärendruck auszugleichen. Danach kann H₁ wieder zugedreht werden, und der Kühlschrank kann geöffnet werden.5. If food is now being imported or exported from the refrigerator, the UV lamps must first be switched off. Then tap 1 (H 1 ) is opened, which allows air to equalize the atmospheric pressure. Then H₁ can be turned back on, and the refrigerator can be opened.
  • 6. Nach dem Schließen des Kühlschrankes kann wiederum der Vorgang der Sterilisation eingeleitet werden: Öffnen von H₂, Einsatz des Kompressors oder der Vakuum­ pumpe, Einschalten der UV-Lampen.6. After closing the refrigerator, the sterilization process can be carried out again be initiated: opening H₂, use of the compressor or the vacuum pump, switching on the UV lamps.
  • 7. Nach einiger Zeit sollte die Luft innerhalb des Kühlschranks ausgetauscht werden. Dabei wird Hahn 1 aufgedreht, der frische Luft hineinströmen läßt; und auch H₂ wird eingeschaltet, und auch der Kompressor, so daß ein Luftzug entsteht.7. After some time, the air inside the refrigerator should be replaced. Turn on valve 1 , which allows fresh air to flow in; and also H₂ is switched on, and also the compressor, so that there is a draft.
  • Dies ist nötig, damit die Atmungsgase der gespeicherten Stoffe, z. B. pflanzliche C₂H₄ (Icillin) entweichen können, wie auch CO₂ (Kohlendioxid).This is necessary so that the breathing gases of the stored substances, e.g. B. vegetable C₂H₄ (icillin) can escape, as well as CO₂ (carbon dioxide).
  • Hierbei können auch unangenehme Duftstoffe entweichen, die bei der Speicherung entstehen.This can also cause unpleasant fragrances to escape during storage arise.

Claims (7)

Es ist zu beachten, daß hier ein Kompressor oder Vakuumpumpe im Kühlschrank oder Kühlbox, oder im Gefrierschrank, installiert werden muß.It should be noted that here is a compressor or vacuum pump in the refrigerator or cool box, or in the freezer. Dies ist für die Erneuerung der Luft im Kühlschrank notwendig, z. B. für das Ent­ weichen der unangenehmen Luft im Kühlschrank.This is necessary for the renewal of the air in the refrigerator, e.g. B. for the Ent give way to the uncomfortable air in the refrigerator. Auch geschieht beim Vakuumprozeß ein Schmelzen des Eises im Kühlschrank. Unter Vakuumbedingungen der Luft, atmet dasjenige im Kühlschrank langsamer als ohne Vakuumbedingungen, z. B. Obst und Gemüse.The ice also melts in the refrigerator during the vacuum process. Under air vacuum conditions, the one in the fridge breathes more slowly than without Vacuum conditions, e.g. B. fruits and vegetables. Dadurch können Obst und Gemüse länger haltbar gehalten werden.As a result, fruits and vegetables can be kept longer. Die UV-Lampen können in jedem beliebigen Kühlaggregat untergebracht werden, wie Kühlbox, Kühlschrank oder sogar Gefrierfach:
  • a) Die Verbindung zwischen Vakuumpumpe oder Kompressor mit UV-Lampen kann in den Kühlräumen eines Schiffes untergebracht werden.
  • b) Dies kann auch für Kühlräume eines Flugzeugs oder
  • c) Kühlkontainer auf Schienen oder
  • d) Kühlschränke eines fahrbaren LKWs verwandt werden.
The UV lamps can be accommodated in any cooling unit, such as a cool box, refrigerator or even freezer compartment:
  • a) The connection between vacuum pump or compressor with UV lamps can be accommodated in the cold rooms of a ship.
  • b) This can also be used for cold rooms of an airplane or
  • c) refrigerated containers on rails or
  • d) refrigerators of a mobile truck are used.
Dieser Vorgang der Konservierung soll vor Einsetzen der UV-Strahlung eingesetzt werden, um zu vermeiden, daß Sauerstoff in Ozongas (O₃)verwandelt wird.This process of preservation should be used before the onset of UV radiation be to avoid that oxygen is converted into ozone gas (O₃). Die lange Konservierung von Gemüse und Obst kann lange haltbar gemacht werden (z. B. für Kartoffel, Zwiebeln, Knoblauch) durch Entweichen der Luft, das zu einem Vakuumzustand führt (1/10 des Außenatmosphärendrucks).The long preservation of vegetables and fruits can be preserved for a long time (e.g. for potatoes, onions, garlic) by escaping the air that too leads to a vacuum state (1/10 of the outside atmospheric pressure).
