DEVICE FOR COLLECTING TEETH-LIQUID OR HIGH-VISCOSE POKKEL BEACON

The invention relates to a device according to the preamble of claim 1.

When pickling pieces of meat they are usually on a surface, such as a conveyor belt, placed and charged with pickle, for example, by the pickle is injected via needles into the meat and / or the meat is partially doused with the pickle. Usually, an excess of pickle is used, with the excess pickle lumps dripping down. In order to prevent soiling from occurring or to minimize the loss of pickle lumps, this excess dripping pickle lice is collected in buckets. These tubs usually have a drain and the pickle-sheets flow by gravity automatically and by themselves there. This principle works very well for thin sheets, but with thick or high-viscosity sheets, there are other conditions and problems arise.

Such heavy-flowing sheets are partially of pudding or honey-like consistency and only slightly low to hardly free flowing, so that a gravity-driven choking only takes place extremely slowly or can only be ensured by a strong slope of the sump. Due to a steep gradient, especially over the total length of the curing pan, however, there is inevitably a very large height difference between the opposite edges of the tub or between the inlet and the outlet. This in turn means that the working height or height of the machinery is very high and in extreme cases, working on the machine is no longer possible without the use of a work platform, which in turn is accompanied by inconvenience and safety concerns. It is generally the working height or the conveyor belt height of such Pökelmaschinen or Pökelinjektoren to keep below a maximum height of 1.2 m in order to meet the security requirements sufficiently.

In addition, for food law reasons, it is often necessary to work at a very low temperature range of about 5 ° to -2 ° C. This causes a further reduction in viscosity and the sheets become gelatinous and even lumpy.

From the AT 410276 B and the AT 501514 B1 Pökelmaschinen are known in which the excess brine is collected in a tub, the drip pan can be cooled. A collection trough, however, is not shown.

In DE 60027582 D2 a device is described in which poultry carcasses are brought into contact with a bactericidal solution, wherein the dripping of the carcasses solution is collected in a gutter.

It thus sets itself the task to provide devices that avoid the disadvantages mentioned above and achieve a reliable removal of viscous or highly viscose pickle sheets at low height.

This object is solved by the characterizing features of claim 1. It is provided that in the trough at least one inclined in a main inclination direction to an outlet and merging into this outlet collecting channel for discharging the pickle is provided, wherein the collecting channel is offset from the bottom surface down or recessed.

The feature that the collecting channel relative to the bottom surface or the bottom surfaces offset downwards or is recessed, it should be understood that thereby a defined and spatially clearly defined by the bottom surfaces recessed channel is formed. As a result of this formation of the collecting trough offset downwards, the heavily flowing pickling beds are collected in a common channel and directed in the direction of the outlet.

The majority of the brine is thereby concentrated in the collecting channel in a small space, whereby friction forces on the surface are relatively reduced. In this way, the brine contained in the collecting trough is transported more effectively and quickly towards the outlet than, for example, would be the case if the brine were distributed evenly over the entire surface of the trough bottom.

In addition, it is easier in this way to promote the brine targeted towards the outlet, for example manually, semi-automatically or automatically, since the brine can not escape laterally. Nevertheless, if the viscous brine does not flow away by itself or by gravity, the formation of the collecting channel can make it easier, faster and easier to remedy this situation than would be the case without a collecting channel. In this way, even with a relatively small slope and a related low height nevertheless effective removal of the brine can be effected.

Particularly advantageous features of the device are defined by the features of the dependent claims.

Thus, for example, when measured in a cross section through the trough normal to the central longitudinal axis of the collecting trough, the lowest point or portion of the collecting trough in this cross section below the fictive extension (s) of the bottom surface (s) or below the Bumper edge of this extension (s) is located. In this way, an effective collection and concentration of brine and a facilitation of the removal takes place.

For an effective collection, it is further advantageous in this context, when the trough is in cross-section normal to the longitudinal axis circular arc, triangular or rectangular.

In order to allow a good introduction of Pökellake into the collecting trough, it is advantageous if the at least one bottom surface is arranged to the collecting trough so that a gradient is formed and the Pökellake is gravitationally infiltrated into the collecting trough.

In this context, it is advantageous if the at least one bottom surface is curved or plane and is inclined and sloping in a side tilt direction normal to the longitudinal axis or normal to the main inclination direction, inclined to the collecting channel. The brine is thus both effectively collected in the collecting trough and simultaneously directed towards the outlet.

A particularly advantageous embodiment results from the fact that the tub has two, in particular gleichdimensionierte, bottom surfaces which are arranged entgegengleich inclined on both sides of the collecting channel. In this way, the bottom surfaces can have a greater inclination and the viscous brine can be transported particularly effectively into the central collecting channel.

An advantageous embodiment of the device further provides that between the bottom surface and the collecting channel in each case an edge is formed, from which increases the inclination or the slope to the solder out. As a result, the pickle is accelerated upon entry into the collecting channel and accordingly also slides more easily along the slope of the collecting channel in the direction of the outlet. Preferred structural embodiments of the collecting trough provide that the collecting trough is in cross-section normal to the longitudinal axis circular arc, triangular, trapezoidal or rectangular.

In this context, it may be advantageous that the collecting channel is circular arc-shaped in cross-section normal to the longitudinal axis and has a width, measured between the two opposite upper edges, which is less than or equal to twice the radius of the collecting trough. In this way, the collecting channel is a little shallower and less deep, which makes it easier to clean and remove impurities.

An alternative, but also advantageous embodiment provides that the collecting channel is circular arc in cross-section normal to the longitudinal axis and a depth, measured from the line between the two opposite upper edges to the Bo the collecting channel, which is greater than the radius of the collecting trough is formed, wherein an undercut is formed by the opposite edges and widens the collecting trough downwards. Such collecting channels have a greater depth and are therefore a little harder to clean. In these constructive embodiments, however, it is advantageous that the pickle flows more effectively into the collecting channel and there is concentrated and safely out. In addition, any transport screws to promote the brine can be stored effectively and safely in this predominantly closed collecting channel.

Another structurally advantageous embodiment provides that the contact angle, measured in cross section normal to the longitudinal axis with the vertex at each edge between the substantially horizontal connection of the two opposite edges and the inclination of the wall surface of the collecting trough, in the range of 30 ° up to 130 °. The smaller the contact angle α is, the lower the gradient in the transition from the bottom surface 4 to the wall surface of the collecting trough. The angle α is therefore a measure of the steepness of the wall surfaces of the collecting trough, regardless of the pitch of the bottom surfaces of the trough. The greater the angle α, the more likely are undercuts possible, that is, at an angle of α> 90 °, a slight undercut already occurs.

In order to effect a transport of the viscous brine in the direction of the outlet, it is advantageous if the trough or the bottom surfaces and / or the collecting trough inclined in the main tilt direction by the angle of 0.5 ° to 5 ° to the horizontal is. Even such low inclination angles are sufficient to effectively transfer even viscous sheets, which also causes a low overall height.

In this context, it is structurally particularly advantageous if it is provided that the bottom surfaces and the collecting channel in the main inclination direction have the same inclination. In this way, the tub can be folded from a common piece of sheet metal.

To further support the transport of Pökellake in the direction of the outlet is advantageously provided that a conveyor device is provided in the collecting channel, such as a screw, a slide or a conveyor belt, with an automatic, semi-automatic or manual, batchwise or continuous displacement or promotion of Poellcake is effected.

Structurally, it is advantageous here if the conveying device is designed as a non-compressing screw conveyor. In this way, the pickle can be transported continuously in the collecting channel. In this context, it is advantageous if the screw conveyor is mounted only on one side or is driven only on one side. The second end is free and the screw is in a sense at the bottom of the collection trough. This is a very simple, yet effective design to carry the pickle to the outlet. It is advantageous in this context if the diameter of the screw conveyor is greater than the height or depth of the collecting trough. In this way, in the upper part is always a section of the auger out, whereby a possible complete transport of the brine is guaranteed.

In order to satisfy food law requirements, it is sometimes necessary that a cooling device is provided for cooling the tub, the bottom surfaces and / or the collecting trough to the temperature of the pickle, in particular in the range between -5 and +10 ° C. hold. As a result, however, the viscosity of the pickle sheets is further reduced and the sheets become less freely flowing with decreasing temperature and accordingly harder to transport. Surprisingly, however, it has been shown that such cooled sheets can be efficiently removed by the embodiment according to the invention.

Another aspect of the invention provides for the use of the device according to the invention for collecting and returning viscous or highly viscose pickle sheets, especially at low temperatures in the range between -5 to + 10 ° C before.

Particularly advantageous exemplary embodiments of the invention are illustrated and described below with reference to the drawings. These are illustrative and non-limiting embodiments to be understood.

In FIGS. 1 to 5, a device according to the invention is shown from unterschiedli chen perspectives.

In Figs. 6 to 11 are cross sections of different wells shown.

In Figs. 12 to 16, another embodiment of a device with inserted screw conveyor is shown.

In Figs. 1 to 5, a first advantageous embodiment of the device according to the invention is shown from different perspectives. FIG. 1 is a top plan view, FIG. 2 is a sectional view from the perspective DD, FIG. 3 is a sectional view from the opposite perspective FF, FIG. 4 is a sectional view taken along the longitudinal axis of FIG Perspective EE and in Fig. 5 is a side view of the device from the outside.

In these drawings, essential parts of a device according to the invention for collecting and returning viscous or highly viscose pickle lobes thereof are shown in detail. The pieces of meat to be injected into the brine are not shown here, as well as the bearing surfaces on which the pieces of meat are placed for the preparation of Pökelung or the Pökelinjektoren or the needles themselves.

In any case, the device comprises a trough 1 for collecting excess pickle lime. The pieces of meat are therefore placed in operation over this tub 1 and the excess pickle drops dripping from the pieces of meat in the tub 1 and is collected in this. The pieces of meat are often transported on a conveyor belt arranged above the tub 1 (see conveyor belt 9 in FIG. 13), but this has been provisionally omitted for the sake of clarity in the current illustration.

The tub 1 has two rectangular, elongated and flat bottom surfaces 4. Centered between the two bottom surfaces 4 a collecting channel 3 is arranged. The two bottom surfaces 4 are mutually inclined in each case in a side inclination direction NN to the collecting channel 3 at an angle of about 5 ° to the horizontal. The angle of inclination of the bottom surfaces in the sub-slope direction NN can also be much steeper. The two bottom surfaces 4 are accordingly both aligned and arranged inclined to the collecting trough 3, that on both sides of the collecting channel 3, a gradient arises, through which the brine can flow into the collecting trough 3 due to gravity along the bottom surfaces 4 approximately in the side inclination direction NN.

The collecting channel 3 is offset from the bottom surfaces 4 and opposite the bottom of the tub 1 down or recessed. This is to be understood that thereby a defined and spatially clear of the bottom surfaces 4 down offset, demarcated recessed channel is formed. In the present case, the collecting channel 3 is trapezoidal in cross-section normal to the longitudinal axis 5 of the collecting channel 3 and the lowest area of the collecting channel 3, so the bottom is arranged as the lowest point of the collecting channel 3 below the fictitious extensions of the two bottom surfaces 4 towards the center. The lowest point or the bottom of the collecting trough 3 thus forms for each cross section in each case the lowest point of the trough 1. In this way, an effective collection and concentration of Pökellake is ensured in the collecting trough 3.

At the transition between the two bottom surfaces 4 respectively to the collecting channel 3, an edge or an edge 6 is formed. From this edge 6, the inclination or the inclination to the solder increases, that is, the inclination is steeper and from the bottom surfaces 4 along the side inclination direction NN slipping Pökellake is even faster at the now steeper wall surfaces 8 of the collecting trough 3 in the collecting trough. 3 slide into. The two edges 6 thus define the boundary between the collecting channel 3 and the bottom surfaces 4.

These edges 6 may be either bent or folded edges, but may also be formed as curved edge regions, in which the slope does not increase suddenly as an edge, but continuously over a certain range.

The depth t of the collecting trough 3 measured from the connecting line between the two opposite edges 6 to the bottom of the collecting trough 3 is less than the width b of the collecting trough 3, measured along the connecting line from one edge 6 to the opposite edge 6. In the present Embodiment, the depth t is about 75% of the width b.

The collection trough 3 opens into an outlet 2 in the form of an exit opening in the trough 1, via which the pickle can be discharged from the trough 1. In order to effect a transport of pickle in the collecting channel 3 to this outlet 2, the collecting channel 3 is inclined in a main inclination direction HN to this outlet 2 out. The inclination angle ß of the collecting channel 3 with respect to the horizontal is about 2 °. The lower the angle of inclination β, the lower can be the overall height of the device as a rule. The two bottom surfaces 4 are inclined at the same angle ß as the collecting channel 3 to the horizontal. The bottom surfaces 4 and the collecting channel 3 are in the present embodiment, for example, made of a uniformly folded according to sheet metal and the bottom of the collecting channel 3 has accordingly the same inclination as the bottom surfaces 4. In this way, a slope forms in the direction of the outlet 2 and the pickle can flow both along the two bottom surfaces 4 and in the collecting channel 3 in the direction of the outlet 2, although the transport in the collecting channel 3 more effective than on the bottom surfaces. 4 expires.

6 to 11 different embodiments of the trough 1 are shown, in each case in a cross section normal to the longitudinal axis 5 of the trough 1 and the collecting trough 3 or approximately normal to the main inclination direction HN. In the middle between the bottom surfaces 4, the collecting channel 3 is shown, wherein at the transition at the edge 6, the sheet is bent down to the solder and the slope of the wall surface 8 in the collecting trough. 3 is increased in it. At this point, that is, at the edge 6, the apex of the contact angle α, wherein the contact angle α between the two opposite edges 6 of the collecting channel 3 and the wall surface 8 of the collecting channel 3 is spanned between the substantially horizontal connection. The contact angle α is in the range between 30 and 130 °, wherein the contact angle α is not only a measure of the steepness of the wall surfaces 8, but also an indicator for the depth t of the collecting trough 3 is. The larger the contact angle α, the deeper the collection trough 3 as a rule.

6 to 10, the collecting grooves 3 are each circular arc-shaped in cross section, in Fig. 11 trapezoidal as in the embodiment of FIGS. 1 to 5.

In Fig. 6, the width b of the collecting trough 3 measured between the two opposite upper edges 6 is smaller than twice the radius r of the collecting trough 3. The contact angle α is less than 90 °, resulting in a relatively shallow collecting trough 3 , Nevertheless, the inclination of the bottom surface 4 is still slightly less than the inclination of the walls 8 of the collecting channel 3 at or just below the edge 6.

In the embodiments of Fig. 8 and 9, the contact angle α are also smaller than 90 ° and there are shallow collecting troughs 3 before. Nevertheless, the collecting channel 3 is clearly defined here and delimited by the two edges 6 of the bottom surfaces 4.

In Fig. 7, the contact angle α is exactly 90 ° and there is here a borderline case in which the wall surface 8 drops directly below the edge 6 perpendicular, but just there is no undercut. The width b here is exactly twice the radius r and the radius r corresponds to the depth t of the collecting trough 3 as measured from the connecting line between the edges 6 to the lowest point of the collecting trough 3.

In Fig. 10, an embodiment is shown, in which the collecting channel 3 is even more pronounced. The contact angle α is about 115 ° and the depth t measured from the connecting line between the edges 6 is greater than the radius r of the circular collecting channel 3. In this way, mutual undercuts are formed by the edges 6, that is, the widest point of the collecting trough third is greater than the width b between the opposite edges 6.

FIGS. 12 to 16 show a further embodiment of the device according to the invention, which is very similar to the device of FIGS. For this reason, the names and explanations are also adopted analogously and it is only on the differences.

A difference lies in the fact that in Figs. 12 to 14, the conveyor belt 9 is shown on which the pieces of meat are placed in operation. The conveyor belt 9 is arranged spatially above the tub 1, so that the pickle can drop into the tub 1.

Furthermore, in the collecting channel 3, a conveyor 7 is arranged in the form of a non-compressing screw conveyor. The auger is located in the collecting channel 3 and serves to support the promotion of Pökellake in the collecting channel 3 in the direction of the outlet 2, ie in the main inclination direction HN. As mentioned in the introduction, the pickle is very viscous, especially at low temperatures in the range between -5 and + 10 ° C and partly gelatinous, so that a free flow takes place hardly or extremely slowly. However, the auger ensures a forced transport of present in the collecting trough 3 Lake. The screw conveyor is mounted or driven only on one side, namely at the outlet 2 opposite end. The other end is free. The diameter of the screw conveyor 3 in this embodiment is greater than the height of the collecting channel 3, that is, the upper regions of the screw conveyor project beyond the fictitious continuations of the bottom surface. 4

Other conveying devices 7 are possible, for example, a running in the collecting channel 3 conveyor belt or a linear along the collecting channel 3 movable slide. The promotion can be done batchwise or continuously. Since the majority of the brine is present centrally and collected in the collecting trough 3, the supportive displacement of the brine by the conveying devices 7 is simple and effective.

Of course, such a conveying device 7 can also be introduced into a device according to FIGS. 1 to 5 or into a trough 1 of FIGS. 6 to 11.

In Figs. 15 and 16, perspective views are provided for this embodiment. Visible is the double inclination of the two bottom surfaces 4 in accordance with the main inclination direction HN and the sub inclination direction NN. Furthermore, it can be seen how the auger in the collecting trough 3 promotes the pickle to the outlet 2 out. This causes the initially mentioned low height or working height, which is indicated by comparison with the representation of a standard person.
