Abstract

The device for retaining the freshness of foodstuffs, in particular fresh vegetables and fresh fruit, in a cooled environment comprises a permanent magnet (1), the food being placed into the magnetic field (4) of the latter. These measures imitate the magnetic field of the earth in the cooled environment, which prolongs the shelf life of, in particular, fresh fruit and fresh vegetables. <IMAGE>

Description

Verfahren und Vorrichtung zum FrischhaltenMethod and device for keeping fresh

von Lebensmitteln in einem Kühlraum Die vorliegende Erfindung betrifft ein Verfahren zum Frischhalten von Lebensmitteln, insbesondere Frischgemüsen und Frischobst in einem Kühlraum.of food in a refrigerator The present invention relates to a method for keeping food, especially fresh vegetables and fresh Fresh fruit in a refrigerator.

Biomagnetische Studien insbesondere an Pflanzen haben gezeigt, dass geerntete Früchte und Gemüse dann einem stärkeren Zerfall unterliegen, wenn diese durch Abschirmung dem Einfluss des Erdmagnetismus entzogen werden. Solche Abschirmungen sind aber bereits dann wirksam, wenn die Früchte und Gemüse in einem Kühlwagen transportiert oder in einem Kühlhaus oder in einem Haushaltskühlschrank gelagert werden.Biomagnetic studies, especially on plants, have shown that Harvested fruits and vegetables are subject to greater disintegration when they are be withdrawn from the influence of geomagnetism by shielding. Such shields but are already effective when the fruit and vegetables are transported in a refrigerator truck or stored in a cold store or in a household refrigerator.

Es ist deshalb Aufgabe der vorliegenden Erfindung, ein Verfahren zu schaffen, das gestattet, durch Schaffung erdnaher Bedingungen in Kühl räumen die Frischhaltung insbesondere von frischgeerntetem Obst oder Gemüse zu verlängern.It is therefore the object of the present invention to provide a method create that allows by creating near-earth conditions in the refrigerated rooms To extend the freshness of freshly harvested fruit or vegetables in particular.

Dies wird beim erfindungsgemässen Erfahren dadurch erreicht, dass die Lebensmittel der Einwirkung eines künstlich erzeugten magnetischen Feldes ausgesetzt werden.In the experience according to the invention, this is achieved by that the food is exposed to an artificially generated magnetic field will.

Durch die Einbringung der Lebensmittel im Kühlraum in ein magnetisches Feld wird die elektrische Leitfähigkeit des Wasseranteiles im Frischobst bzw. Frischgemüse soweit an erdnahe Bedingungen angepasst, dass die Bildung der Fäulnisbakterien vergleichsweise erheblich verzögert wird und so die eingebrachten Früchte und Gemüse erheblich länger frisch bleiben.By placing the food in the refrigerator compartment in a magnetic one Field is the electrical conductivity of the water content in fresh fruit or fresh vegetables adapted to near-earth conditions so that the formation of putrefactive bacteria comparatively is significantly delayed and so the brought in fruits and vegetables much longer stay fresh.

Ferner betrifft die vorliegende Erfindung eine Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens, welche sich auszeichnet durch zum Einbringen in den Kühlraum geeignete Mittel zur Erzeugung eines magnetischen Feldes.The present invention also relates to an apparatus for implementation of the method according to the invention, which is characterized by the introduction suitable means for generating a magnetic field in the cooling room.

Hierbei können diese Mittel zur Erzeugung des magnetischen Feldes einen zweckmässig batteriebetriebenen Elektromagneten oder einen Permanentmagneten umfassen, welche Mittel zweckmässig von einerhygienischen Hülle umgeben sind.This means for generating the magnetic field an expedient battery-operated electromagnet or a permanent magnet include, which means are expediently surrounded by a hygienic cover.

Für eine variable und nichthindernde Anordnung der Vorrichtung 'im Kühlraum ist diese zweckmässig mit Klammer-oder Hakenmittel versehen.For a variable and non-obstructive arrangement of the device 'in the This cooling space is expediently provided with clamps or hooks.

Eine beispielsweise Ausführungsform des erfindungsgemässen Verfahrens ist nachfolgend anhand der Zeichnung, welche schaubildartig eine Vorrichtung zur Durchführung des Verfahrens zeigt, näher erläutert.An example embodiment of the method according to the invention is below with reference to the drawing, which is a diagram of a device for Implementation of the method shows, explained in more detail.

Um zur Durchführung des Verfahrens gemäss Einleitung die Lebensmittel, wie insbesondere frischgeerntetes Obst oder Gemüse innerhalb eines nicht näher gezeigten Kühlraumes der Einwirkung eines künstlich erzeugten magnetischen Feldes auszusetzen, umfasst eine hierfür geeignete und in den Kühlraum einzusetzende Vorrichtung einen Permanentmagneten 1. Dieser erzeugt ein durch die Linie 4 angedeutetes Magnetfeld, das den Kühlraum sowie die darin untergebrachten Lebensmittel durchdringt.In order to carry out the procedure according to the introduction, the food, such as, in particular, freshly harvested fruit or vegetables within a not shown in detail To expose the cold room to the action of an artificially generated magnetic field, A device suitable for this purpose and to be inserted into the cooling space comprises a Permanent magnets 1. This generates a magnetic field indicated by line 4, that penetrates the refrigerator compartment as well as the food stored in it.

Dieser Permanentmagnet 1 ist von einer, den hygienischen Anforderungen genügenden Schutzhülle 2, welche ein Kunstharzbelag sein kann, umgeben. Ein Haken 3 gestattet eine Aufhängung der Vorrichtung im Kühlraum.This permanent magnet 1 is one of the hygienic requirements sufficient protective cover 2, which can be a synthetic resin covering. One catch 3 allows the device to be suspended in the cold room.

Natürlich werden die gleichen Effekte auch durch einen, zweckmässig batteriegetriebenen Elektromagneten erreicht. Ferner können die Hakenmittel auch durch Klemmmittel ersetzt werden.Of course, the same effects are made useful by one battery-powered electromagnet achieved. Furthermore, the hook means can also be replaced by clamping means.

Die vorbeschriebene Vorrichtung ist einfach und kostengünstig herstellbar und kann so von jedermann erworben und angewendet werden.The device described above is simple and inexpensive to manufacture and can thus be acquired and used by everyone.
