Definitions

  • the invention relates to a loading container for a plant for the disinfection of food, in particular, which forms a receptacle for the food and can be used in a chamber of the disinfection plant for the food to be disinfected on the surfaces.
  • the foodstuffs have hitherto usually been filled into sacks and then used in the treatment chamber of this system for disinfection.
  • a vacuum is first created in the chamber and then steam is blown in, for example at a temperature above 100 ° C. This steam is then left in this chamber for a predetermined period of time, so that the cargo filled in sacks can sterilize.
  • a relatively long treatment time is required until these foods are sterilized on the surfaces of the bags in the center.
  • the present invention was based on the object to create a loading container of the type mentioned, which is simple and easy to use and with it a shorter treatment time compared to the known container is achieved with a uniform penetration of the cargo. Furthermore, this loading container is also intended to enable perfect disinfection of powdered or particularly sensitive foods.
  • the object is achieved in that a plurality of hollow bodies made of a vapor-permeable material are provided, into which the food can be filled.
  • the foodstuffs filled into these be they powdered or otherwise, can be sterilized very efficiently and in a very gentle manner.
  • Such loading containers are also easy to manufacture and they allow easy operation when loading the disinfection system.
  • These hollow bodies are each very advantageously made of a stainless steel, a plastic or a textile fabric in a cylindrical shape, which enables sufficient gas permeability and the food filled into the hollow body is quickly and evenly penetrated by the steam.
  • a drying device is provided according to the invention, by means of which the food sterilized in this chamber in the loading containers can be acceleratedly dried, thereby further shortening the treatment time while maintaining or even improving the quality disinfection is achieved.
  • FIG. 1 is a perspective view of a loading container according to the invention
  • FIG. 2 shows a front view of a loading container with a different number of hollow bodies compared to that according to FIG. 1,
  • FIG. 3 shows a front view of two stacking feed containers according to the invention.
  • FIG. 4 shows a partial longitudinal section of a hollow body of the loading container according to FIG. 3.
  • FIG. 1 shows a loading container 10 for a disinfection system, not shown in any more detail, in which, in particular, foodstuffs are advantageously sterilized only on the surface.
  • the treatment can be powdered foods, such as flours, peppercorns, tea leaves, mushrooms, cut roots or the like.
  • Such a sterilization system expediently has a lockable chamber in which one or more loading containers 10 with an untreated food are used. The disinfection is carried out in this chamber a program-controlled sequence is carried out in the manner known per se.
  • a plurality of hollow bodies 15, at least partially made of a vapor-permeable material, are provided, into which the food can be filled.
  • these hollow bodies 15 are formed from elongated cylinders which are held in a frame arrangement in a parallel arrangement to one another.
  • This frame consists of several interconnected outer frame strips 16, 18 and reinforcing profiles 17, 19, on which the cylindrical or tubular hollow bodies 15 are held in ten rows one above the other, each with nine or eight hollow bodies 15 per row.
  • the latter are provided with identical lengths and each end is fastened in a side plate 11 held by the frame, to which openings 14 arranged concentrically to the hollow bodies 15 are assigned.
  • These openings 14 of the side plates 11 can each be sealed by an indicated cover 13, which is pivotally mounted, for example, laterally on the frame via hinges 13 'or the like. All components of this container 10 are each made of a stainless steel.
  • This configuration of the loading container 10 results in a further advantage in the context of the invention in that this container 10 can be placed in a vertical position when filling with food, in which the rear lid 13 is already closed beforehand. The corresponding foods can then be filled into the openings 14 by hand or mechanically into the individual cylinders 15. After loading, the front lid 13 is also closed and the container 10 can then be tilted back into the horizontal position shown, in which it is used in the disinfection plant. In this horizontal position, the food for disinfection is kept in an optimal distribution in these cylinders.
  • passage channels 12 are formed, through which all the hollow bodies 15 are acted upon by steam all over their entire length, the steam being let into a chamber of the system enclosing the container 10.
  • the steam can therefore penetrate evenly into the interior of the cylinder and sterilize the food contained therein.
  • the distances between the hollow bodies 15 are preferably as small as possible, i.e. up to a few millimeters. This enables a maximum number of cylinders per volume and it is nevertheless ensured that the individual cylinders, even those located in the center of the container, are adequately supplied with steam.

  • This stainless steel or plastic mesh of the hollow body is advantageously provided with a vapor permeability such that powdered food can be accommodated in this hollow body without it Powder would leak out of the hollow body during disinfection.
  • the maximum possible steam entry should be ensured in order to achieve optimum disinfection.
  • FIG. 2 shows a loading container 20 which is constructed in the same way as that of FIG. 1 and is therefore no longer explained in every detail.

  • These centering means 33, 34 are designed as cooperating tongue and groove connections 33, 34.
  • a cross support 38 is attached approximately in the middle of the frame to increase the stability of the container 30.
  • such containers can have a height or length of up to approximately one meter and the diameter of the hollow bodies can be up to 150 millimeters.

Abstract

L'invention concerne un récipient de chargement (10) pour installation de stérilisation, notamment de pasteurisation d'aliments, qui constitue un espace de réception pour les aliments et peut être introduit dans une chambre de l'installation de pasteurisation pour les aliments à pasteuriser sur les surfaces. Ce récipient de chargement (10) présente plusieurs corps creux (15,35) maintenus à distance les uns des autres, qui sont réalisés dans un matériau perméable à la vapeur et dans lesquels les aliments à pasteuriser peuvent être introduits. Chacun des corps creux (15,35) est produit de manière appropriée à partir d'acier, de matière plastique ou d'une structure textile. Cette mesure permet d'effectuer une pasteurisation optimale des aliments chargés dans lesdits corps creux.
