Description

Description " MEAT DRIPPING DEVICE FOR DRYING MEAT " The invention relates to a meat grinder for drying meat according to the preamble of claim 1.

Refrigerators are known from the prior art, which are used for the dry maturation of meat and provide a limited volume in the context of a commercial refrigerator size for receiving the meat. Meat ripening is sometimes referred to as hanging. Immediately after slaughter, meat is usually tough and tasteless. Only by a corresponding maturation, usually in the form of a storage, it is tender, multifaceted in taste and usually also wholesome. Particularly well known is the meat ripening in beef, especially in the preparation of steaks, which is usually used beef over Drying for a long time. Not infrequently, such beef is stored dry for several weeks.

The object of the invention is to be able to provide a particularly hygienic meat gripping device.

The object is, starting from a meat grinder device of the type mentioned, solved by the characterizing features of claim 1.

Advantageous embodiments and developments of the invention are possible by the measures mentioned in the dependent claims.

Accordingly, the meat grinder according to the invention for dry maturing meat is characterized in that the chamber has a one-piece, in particular jointless plastic container, which is arranged so that it forms the inner lining of the chamber. The meat gripper comprises a chamber, but no walk-in space, since it is in the form of a refrigerator (freestanding or, for example, in a wall integratable) formed with the appropriate dimensions. The chamber is used for receiving and storing the meat during the maturing process.

The use of plastic according to the invention has several advantages: [0008] On the one hand, the plastic is generally very easy to clean.

In addition, the plastic is very hygienic, since it usually antibacterial

Has properties and in particular may be even more hygienic than, for example, some metal surfaces.

On the other hand, it has the advantage over stainless steel that it is cheaper at the

Manufacturing is and can also be made simpler and cheaper, since no elaborate processing methods are necessary, but the plastic container, e.g. can be produced by deep drawing or in total in a corresponding Spritzgu߬form.

By the further measure, integrally formed in a particularly preferred Ausführungsvarianteden plastic containers, joints are avoided in which germs or dirt can accumulate. Even when cleaning residues can thus not reach the appropriate joints.

The plastic container forms the inner lining of the chamber, i. it thus comes into contact with the air that surrounds the ripening meat. Since it can not be ruled out that the meat itself is contaminated with germs and that they can be passed on via the air, it must be expected in principle that germs come into contact via the air or directly via the meat which comes into contact with the inner wall , Ablagern there and thus can also germinate the meat grinder. Since the plastic can have antibacterial properties and is also easy to clean, hygiene can thus be decisively improved.

It is therefore particularly advantageous if the interior is provided on as many sides miteiner plastic surface. The door of the chamber is usually formed as a separate component, if necessary, it also has a glass. Accordingly, the plastic container can be formed on at least three sides, namely in particular on the inside opposite the door and on the two laterally adjacent walls. In addition, the bottom and the ceiling can still have a plastic inner wall, so that the plastic container is at least 3, but generally at most 5 sides the interior limits. In this way, the hygiene can be improved again. The Ab¬ washability is, especially in a jointless container, given here in a special way. Even on the ground, where under certain circumstances, meat juice or water deposits (zBbeim defrosting) accumulate on the ground and there must be removed by cleaning, can particularly advantageous when the seamless plastic container also extends over the bottom.

In addition, it is also conceivable that the door of the meat grinder has a Kunststoffin¬nenwand. In addition, it is conceivable that the glass panel is coated with a transparent plastic or a transparent plastic is used in the door.

In order to manufacture a container which is as seamless as possible, it can be deep-drawn in particular, i. a heated, flat plastic plate is deformed in a mold at least on the sides so that a trough is formed. Especially in this manufacturing process, the tub can be produced as possible without ridges in the interior and otherwise without joint. This is a particularly favorable manufacturing method, which is particularly suitable for mass production.

To obtain an antibacterial and particularly hygienic, easy-to-clean plastic, polystyrene can be used at least partially as a plastic.

In principle, it is also conceivable that a composite material is used in which the inner wall has a polystyrene layer. Polystyrene is inter alia against aqueous Lau¬gen and against some acids. Polystyrene components can be very light due to the low density. Polystyrene is also advantageously suitable for fabrication in an injection molding process.

Embodiment

An embodiment is illustrated in the drawings and will be explained in more detail below with further details and advantages.

[0020] FIG. 1 shows a schematic representation of a meat gripping device according to the invention (in front view); FIG. 2 shows a schematic representation of the sterilization device in the meat-removing device according to FIG. 1; [0022] FIG. 3: a schematic representation of the lower part of the housing of the sterilization device; Figure 4 is a schematic representation of the activated carbon filter and its attachment in the meat gripping device according to Figure 1, and Figure 5 is a schematic representation of a plastic inner container.

Figure 1 shows a meat gripping device 1 in the shape and size of a refrigerator. The meat gripper 1 has for this purpose an interior or a chamber 2 for receiving and storing the meat 3, 3 '. In the drawing, this chamber 2 is separated from the environment at the front by a door 4, which is designed to be openable. The door 4 is a handle 5 open and closed. In addition, the door 4 comprises a darkened glass pane 5. Inside the chamber 2 are located on the side walls, a Lagerungsvor¬richtung 6, 7, in each case partial storage devices TL, which have groove-like cuts with contact surfaces to support devices such as a grate 8 or a single transverse web 9 to be able to hold. In the upper part of the ceiling there is a sterilization device 10. In the lower part of the chamber 2 there is an activated carbon filter 11, which is incorporated in a throughbore of the wall and through which the chamber 2 is connected to the outside air.

The sterilization device is shown in schematic section in Figure 2. It has a housing 20 which has an opening 21 on one side and is likewise provided with opening slots 23 on the opposite side. In addition, a blower 24 is provided, which sucks in the air and passes through the blower. In area 21, the air can flow as indicated by arrow 25. In addition, vertically extending plates 26a, 26b, 26c, 26d are provided, which are alternately mounted in the lower region (plates 26a, 26d) or in the upper region (plates 26b, 26c) of the housing. On the way through the housing 20, the air must therefore take a kind of meandering course. Between the plates 26b, 26c, a UV lamp 27 is provided which in particular emits UV-C radiation.

So that the UV lamp 27 is not cooled by the air flow, it is surrounded by a glass housing 28. As a result, between the lamp 27 and the glass housing 28 forms a gap, which is used for insulation, in particular for thermal insulation. Optionally, the gap may be suppressed, filled with a special gas, or vacuumed. The housing 20 and the diaphragms 26a, 26b, 26c, 26d prevent UV light from penetrating into the ripening chamber 2 where it directly irradiates and damages the walls, which are primarily made of plastic, or strikes the meat directly. Such a direct irradiation would be disadvantageous because it could cause damage not only to the walls of the chamber but also to the meat and, moreover, in some countries direct irradiation with UV-C light from meat is prohibited. In Figure 3, the lower part of the housing (without screens) is shown again in an oblique view.

Figure 4 shows a section of the lower portion of the meat gripper device 1 with the activated carbon filter 11. This is embedded in a not shown in detail through bore of the rear wall of the meat gripper device 1. In addition, an enlarged view of the activated carbon filter 11 can be seen in FIG. The activated carbon filter consists essentially of an air-permeable housing in which activated carbon is stored as granules. When the chamber 2 is cooled down from room temperature (about 25 degrees Celsius), the pressure in the chamber 2 is reduced and air sucked from the outside. This air can flow through the Aktivkohlefil¬ter 11 and is filtered by the activated carbon.

The activated carbon filter 11 in turn has a mechanism by which it can be easily removed by Zusammen¬drücken the front tabs and by turning.

In addition, a single transverse web 9 is shown in FIG. In the direction of the drawing plane in FIG. 1, a plurality of individual webs can be arranged one behind the other. The actual transverse web 9a is offset from the storage units 9b and 9c when they are at a height in the horizontal direction. For this purpose, connecting webs 9d, 9e are provided, which are connected to the transverse web 9a. The crossbar 9a thus enables a bridging of the height, because the individual storage units 6, 7 are not mounted continuously up to the top below the ceiling in the rule. Just when a piece of meat, such as a cattle half 3, suspended, this can be hung at a higher point and thus space-saving housed in the meat gripping device 1. If appropriate, therefore, another piece of meat 3 'on a grate 8 below has room.

In the embodiment of Figure 1 no insertion grooves are no longer provided in the upper region X, so that if a flat extending rust would be pushed into the uppermost groove, the space above can be used at most for the storage of meat. But if a long piece of meat requires the greatest possible height for hanging, otherwise this place can no longer be used. The described single transverse web 9, on the other hand, makes it possible to use this free space even in such a case.

Figure 5 shows a plastic inner container 30 which is seamlessly formed by being manufactured by a deep drawing process. The container 30 limits the chamber 2 to four sides and can be washed out virtually without residue, whereby a special level of hygiene is enabled.

The meat gripping device can not only be in the form of a classic refrigerator with a swing door. It is also possible, for example, to design the meat gripping device as a display case, in particular with sliding doors.

Especially in an embodiment with plastic inner walls, it is also conceivable to provide one or more veneers. For example, the back wall in the chamber can be provided with a veneer, for example made of stainless steel, with which, for example, the air duct can be influenced and / or the evaporator can be protected. The veneer does not have to blind the entire wall, but can only partially cover it. Stainless steel is also characterized in principle by the fact that it can fill a high standard of hygiene, is inert and easy to wash off.

Furthermore, the light source for generating UV light in the housing can be arranged not only transversely to the direction of flow, as shown in Figure 2, but also along the direction of flow Strö¬. In addition, it may be advisable to provide a mounting device, for example in a housing, for mounting the light source, in particular a screw device.
