Description

Technical area

The present invention relates to a processing device for processing kitchen waste, in particular for processing organic kitchen waste in commercial kitchens, canteens, hotels, communal catering facilities and in the catering trade.

State of the art

Organic kitchen waste in the form of catering waste and equipment waste, for example, in large kitchens, canteens, hotels, communal catering and in the catering every day in large quantities. This organic kitchen waste can be used as a raw material for the production of renewable energy in biogas reactors. For this purpose, it is necessary to treat the organic kitchen waste so that they are storable and transportable. Organic kitchen waste can roughly be divided into two different categories, namely food waste and set-aside waste. The division results both from the place of origin and from the character of the respective organic kitchen waste.

Food waste is understood as the remains of already prepared food. Food waste, for example, in the return of plates and trays by the respective guests, employees or patients, before these plates or trays are rinsed. For example, in hospitals, food waste typically accumulates around 250g per patient and meal. Also in the catering trade, hotel industry as well as in canteens large quantities of food waste accumulate.

In the preparation of food falling into the respective kitchens at the set-up equipment Waste, for example, fruit and vegetable husks, lettuce leaves and cabbage leaves, roots and other organic remains of not yet prepared food raw materials, which are prepared for the actual food preparation.

For disposal and storage of organic kitchen waste, a system is known in which the organic kitchen waste is placed in a disposal device in which they are crushed by means of a crushing device in the form of a grinder, partially with the addition of water so that they subsequently in a largely homogenized form can be pumped into appropriate storage tanks. From these storage tanks, the then largely homogenized biomass is transported by means of a transport vehicle to a biogas plant, in which the biomass is fermented without further treatment, wherein the fermentation resulting in fermentation gases, especially methane gas, for generating electrical energy and / or heat energy is used. In this way, organic kitchen waste can be recycled and recovered from this environmentally friendly renewable energy.

In this processing device, a grinder comminutes the kitchen and food wastes at 1000 to 2000 revolutions per minute. Since contact with the rotating parts of the grinder can lead to the most serious injuries, 100% working safety must be guaranteed.

It should be noted that for ergonomic reasons an easily accessible and usable for the operator height of such a processing device is essential, which is usually between 850 and 950 mm.

From the DE 20 2011 050 658 U1 For example, a disposal apparatus for organic kitchen waste is known, in which the working safety is provided by a lid which is equipped with a safety switch, which allows the operation of the crushing device only when the lid is closed. Accordingly, continuous operation for large volumes is not possible, but only one batch operation is possible.

Presentation of the invention

Starting from the known state of the art, it is an object of the present invention to provide a processing device which enables a continuous loading of kitchen waste in a safe operation.

This object is achieved by a device having the features of claim 1. Advantageous embodiments emerge from the subclaims.

Accordingly, there is proposed a processing apparatus for processing kitchen waste comprising a shredder for shredding the kitchen waste, a feeder for feeding uncut kitchen waste to the crushing apparatus, and a machine cover covering the feeder at least during operation of the crushing apparatus. According to the invention, the machine cover has a feed opening having an engagement protection for feeding uncut kitchen waste into the feed device.

By providing the feed opening, the feed device and thus the comminution device can also be loaded during operation of the comminution device when the machine cover is closed. The intervention protection at the same time provides effective protection of the operator. This makes it possible to efficiently feed even large quantities of kitchen waste without interrupting the production process. This is particularly important in the field of retraction of dishes on a conveyor belt, for example in a canteen of great importance.

The intervention protection ensures that an injury during operation is virtually eliminated. Accidental or intentional interference or slipping into the machine cover's feed opening is hindered by the intervening guard so as to preclude contact with the comminution device and thereby operator injury.

The feed of the uncut kitchen waste via the feed opening preferably takes place substantially centrally with respect to the feed device and from above the comminution device, so that the risk of blockages of the feed device by the uncut kitchen waste is reduced. Furthermore, the use of water to flush the kitchen waste into the crusher can be minimized, or the use of water for flooding the uncooked kitchen waste into the crusher can be completely eliminated. In other words, the feed opening is preferably provided substantially vertically above the comminution device, which is provided for example in the form of a grinder, in the machine cover.

The engagement guard preferably has a protective cover which at least partially overlaps the feed opening and which is spaced from the feed opening on the machine cover is arranged. The overlap in the plane of the machine cover ensures that direct intervention by an operator through the feed opening is avoided.

In order to enable an obstacle-free handling, the protective cover is preferably arranged on the side of the machine cover facing the feed device. With the machine cover closed, the protective cover is thus below the feed opening, so that while an intervention of an operator is avoided in the feeder, the traffic area above the feed opening but is not affected by the protective cover.

A preferred form of the protective cover is a polygonal shape. Due to the polygonal shape, the provided angles can be adjusted accordingly to the rest of the geometry.

Particularly preferably, the protective cover has a tapering in the direction of the feed opening form, preferably a conical shape, a composite of at least two segments shape or a pyramid shape. Kitchen waste that hits the protective cover can easily drain downwards without the need for an operator to move in here. Also on the basis of this embodiment, the safety can be further increased, since an operator does not feel the need to resort to pushing the kitchen waste into the feed opening.

In order to ensure optimum protection depending on the potential hazard, but at the same time also to achieve a trouble-free inputting of kitchen waste, the protective cover preferably has a greater overlap at the end of the feed opening facing away from the operator than at the end of the feed opening facing the operator. Thus it can be achieved that the operator, if he slips, does not get into the danger zone of the comminution device.

In order to increase the working safety already by the shape of the feed opening, the feed opening has the shape of a planar polygon, preferably a polygonal shape having at least one acute angle. At the acute angles, the limbs of an operator catch as he engages through the delivery port, thus blocking over-insertion of the limbs into the delivery port in this manner. This further reduces the risk of intervention in the comminution device.

The feed opening may preferably have the shape of a planar quadrilateral, particularly preferably a kite quadrilateral, a deltoid or a rhombus. The present in these forms acute angle reliable braking, jamming or blocking of the limbs and thus a reliable intervention protection can be achieved.

In a further development, the number of corners of the protective cover differ from the number of corners of the feed opening. Due to the different polygonal design of the feeder and the protective cover so different large overlap areas can be formed, which are formed according to the anticipated engagement good health and safety at the same time good Einbringverhalten the kitchen waste.

In order to enable a simple introduction of large amounts of kitchen waste into the processing device, a feed plate for placing the kitchen waste in the machine cover is preferably provided and the feed opening is arranged in the feed plate. Preferably, the feed plate is inclined towards the feed opening and particularly preferably has the shape of an inverted truncated pyramid, a funnel or a shape composed of at least two segments.

The engagement guard also advantageously has at least one transverse strut extending in the plane of the machine cover, which crosses through the feed opening and which preferably encloses an acute angle with an edge of the feed opening.

For the operator, in particular, the corners of the feed opening pose a risk of unintentionally entering the danger zone of the processing device. Over the corners, an operator may accidentally get into the feed opening with the elbow, forearm, hand, or other extremities. If the corner is defined by an acute angle, the area narrows so much that the extremities can not pass through the feed opening there. Furthermore, the extremities are clamped in the respective acute angles, so that further insertion is prevented. In this case, despite the narrowing by the acute angle, the base of the feed opening remains large, so that a large substance throughput is possible.

The engagement guard may further include at least one support strut extending out of the plane of the engine cover, preferably for spaced retention of a protective cover.

By the support strut, the gap between the feed opening and protective cover can further be divided so far that too deep engagement can be prevented.

Furthermore, the feed device is preferably dimensioned such that the engagement protection cooperates with the feed device in such a way that intervention of an operator in the comminution device is prevented.

Detailed description of preferred embodiments

In the following, preferred embodiments will be described with reference to the figures. In this case, identical, similar or equivalent elements in the different figures are denoted by identical reference numerals and a repeated description of these elements will be omitted in the following description in part in order to avoid redundancies.

In the FIGS. 1 to 8 a processing device 1 in a first embodiment in different perspectives and in a sectional view is shown.

FIG. 1 shows a schematic perspective view of a processing device 1, which is used for processing and disposal of organic kitchen waste, especially food waste or set-up waste. Such a processing device 1 is usually provided in a canteen kitchen, a canteen or other food processing operation, for example, to process the resulting organic kitchen waste, which is produced during the production of food. With such a processing device 1 and organic kitchen waste can be processed in the form of returning food, which were not consumed by the guests. The processing apparatus 1 is either in the area of the setup stations in which organic food is pretreated, for example peeled, or in the field of rinsing stations, in which trays and plates are emptied with food waste, arranged to process the respective accumulating organic waste.

The processing apparatus 1 comprises a base housing 10 and a machine cover 12 which, as can be seen for example FIG. 2 can be opened to a funnel-shaped feed device 20, which the organic kitchen waste finally to a crushing device 22, which for example in the sectional view in FIG. 5 indicated schematically supply. In the comminution device 22, the organic wastes are ground into an easy-to-pump slurry which can then be disposed of.

In the FIGS. 1 to 8 the processing apparatus 1 is shown in different views. In FIG. 2 For example, the processing apparatus 1 is shown with the machine cover 12 open, such that the funnel-shaped delivery device 20 is clearly visible. Furthermore, it can be seen that the feeding device 20 can be substantially hermetically sealed to the machine cover 12, wherein in the machine cover 12, a hood-shaped inner region 120 is provided, which forms a sealing edge 122, which can be brought into engagement with a corresponding seal receptacle 112 on the base housing 10 is. At the sealing edge 122 and / or the seal receptacle 112, an elastomeric seal can be inserted, by means of which a completely hermetic sealing of the machine cover 12 with the base housing 10 and in particular with the feeding device 20 is achieved. Thus, the funnel-shaped supply device 20 is sealed at the top, so that splashing out of processed in the processing device, such as organic kitchen waste is prevented.

The machine cover 12 further provides protection which prevents an operator from interfering with the feeder 20, and in particular the shredder 22, during operation. Such intervention in the comminution device can lead to severe injury to the operator and must therefore be avoided in any case. This is particularly the case, since the overall height of the processing device 1 is designed so that it can be easily reached by an operator, and in particular the top edge of the machine cover 12 is located at the usual in kitchens working height between 850 and 950 mm. Here the danger is particularly great that through Slipping or other uncontrolled unintended movements can reach the extremities of an operator in the danger zone of the processing device 1.

Accordingly, an operation of the processing apparatus 1 is possible only when the machine cover 12 is closed. For this purpose, inter alia, a safety switch 3 is provided, which only allows starting of the comminuting device 22 when the machine cover 12 is completely closed. The safety switch 3 further provides for an immediate stop of the crushing device 22 when the engine cover 12 is opened. The safety switch 3 is how, for example, off FIG. 5 results, provided in the region of the connection of the machine cover 12 on the base housing 10. In the illustrated embodiment, the safety switch 3 is disposed on the axle supporting the engine cover 12. In other embodiments, the safety switch may also be provided at other positions.

In order to allow easy opening and closing of the machine cover 12, a handle 124 is attached to the front of the machine cover 12, on which the machine cover can be opened upwards. As can be seen for example from the schematic sectional view in FIG. 5 results, the machine cover 12 is provided with a schematically illustrated opening aid 126, for example in the form of a steel spring mechanism or a motor support. In this way, the machine cover 12 in the example in the FIGS. 2 to 4 shown open position, for example, to perform cleaning and maintenance, or to solve any blockages occurring in the processing machine.

In order to enable a continuous feeding of the processing device 1 with substances to be processed, for example kitchen waste, a feed opening 4 is provided in the machine cover 12, via which uncrushed kitchen waste can be fed into the feed device 20 and thus finally into the comminuting device 22. The supply port 4 is disposed in a central portion of the machine cover 12 in the illustrated embodiment and accordingly enables the convenience of introducing kitchen waste into the feeder 20. For feeding the kitchen waste through the feed opening 4 into the feeder 20, it is not necessary to feed the machine cover 12 open, so that a feed can take place during operation of the crushing device 22.

In order to enable a simple and overflow-free feeding the kitchen waste into the feed opening 4, a task plate 40 of the machine cover 12 is provided, on which, for example, plates and trays can be easily distributed without the operator would have to aim very precisely in the feed opening 4. The task plate 40, in which also the feed opening 4 is arranged, is slightly funnel-shaped. In the illustrated embodiment, the feed plate 40 of the machine cover 12 includes five segments which form a slope of the feed plate 40 to the feed opening 4, so that kitchen waste, which does not get directly into the feed opening 4, can flow into the feed opening 4, or at least not can flow over the machine cover 12 away to the outside.

This feeding can take place without the addition of further water, so that the water consumption of the proposed processing device 1 is very low, which is also reflected in a cost savings, since the additional volume of water does not have to be disposed of.

In order to prevent an intervention of an operator through the feed opening 4 into the crushing device 22, the feed opening 4 is provided with an engagement guard 5. The engagement protection 5 has in the embodiment shown on several elements that form the desired protective effect in interaction, but also individually.

On the one hand, a protective cover 50 is provided which is arranged on the inside of the machine cover 12, that is to say on the side of the machine cover 12 facing the feeding device 20 or the comminuting device 22. The protective cover 50 is, as can be seen for example from the FIGS. 2 to 5 results so spaced from the feed opening 4 arranged that exists between the feed opening 4 forming edges 42 in the feed plate 40 of the machine cover 12 and the protective cover 50, a sufficiently extensive gap through which the kitchen waste can get into the feeder 20.

The protective cover 50 is in the in the FIGS. 1 to 8 shown first embodiment, as is apparent from the figures directly, and in particular from FIG. 4 , is formed so that it completely overlaps the feed opening 4 in the plane of the machine cover 12. In other words are the edges 42 of the feed opening 4 viewed in a direct plan view of the protective cover 50. In the in the FIGS. 1 to 8 In the embodiment shown, the protective cover 50 is embodied as a seven-cornered one and has, in particular, six triangular segments 500 which are assembled in a pyramidal shape such that kitchen waste, which reaches the protective cover 50 through the feed opening 4, becomes one side, depending on the location of impact on the protective cover 50 flow out into the feeder 20 towards or even on all sides and get into the crushing device 22 on a short path. The protective cover 50 is correspondingly pointed to the feed opening 4 formed, as can be seen for example from the side view in FIG. 3 or the sectional view FIG. 5 directly results.

The outline shape of the protective cover 50 does not correspond in the embodiment shown with the shape of the feed opening 4. The feed opening 4 is formed substantially in the shape of a kite quadrilateral or a deltoid. It can be achieved in this way that, in combination with the underlying protective cover 50, an intervention by an operator in the comminution device 22 is ruled out, since the angles occurring are too acute for them to be penetrated by the extremities of an operator without the extremities would get caught in the pronounced acute angle. In other words, the intervention of an operator by the feed opening 4 is automatically blocked by the geometric shape of the feed opening 4 itself in combination with the geometric shape of the protective cover 50 in combination with their spacing from the edges 42 of the feed opening 4.

The engagement protection 5 comprises as a further element a transverse strut 52, which extends substantially in the plane of the machine cover 12. The cross member 52 passes through the supply opening 4 in such a way that the supply opening 4 is subdivided. The cross member 52 causes characterized in that more acute angles between the edges 42 of the feed opening 4 and the cross member 52 arise, in which in turn limbs of an operator can catch, such that engagement by the feed opening is not possible, or by capturing the Limbs is blocked.

Further, the engagement guard 5 includes support struts 54 provided primarily for holding the protection cover 50 to the engine cover 12 at the predetermined interval. The support struts 54 extend from the machine cover 12 and serve at the same time also to subdivide the feed path through the feed opening 4 even smaller, so that an intervention by an operator in the comminution device 22 is also prevented here.

A holding strut 54 may also be arranged on the cross strut 52, so that the cross strut 52 may also have the property of a holding strut, since it carries a holding strut 54 for holding the protective cover 50.

In the FIGS. 7 and 8 Again, the machine cover 12 is shown alone and in perspective views to illustrate the interaction between the design of the feed opening 4 and the engagement guard 5. The feed opening 4 defining edge 42 in the feed plate 40 of the machine cover 12 is in the form of a polygon, wherein the polygon has four corners and has substantially the shape of a kite quadrilateral, a deltoid, a diamond or a rhombus.

The kite quad, shown in the figures, gives an acute angle 420 at the corner of the edge 42 facing the operator. At this acute angle 420, which represents the most vulnerable position since it is most directly associated with the operator, serves to Then catch extremities of the operator when he accidentally wants to intervene through the feed opening 4.

The transverse strut 52 further acute angles at the positions 422, 424, 426 and 428 are formed, which also the extremities of an operator who inadvertently engages through the feed opening 4, capture. This is for example in the FIGS. 7 and 8 illustrated.

In the area of the angle 429, which represents the angle farthest away from the operator, although intervention can take place over a certain distance - a deep penetration into the feed device 20 is not possible because, as for example FIG. 5 Immediately results, the operator abuts the wall of the feeder 20.

For general coverage of the feed opening 4 downwards, the protective cover 50 is provided, which prevents a direct intervention from above into the feeding device 20 into it. Due to the overlapping training a direct, so vertical, intervention is immediately prevented.

However, kitchen waste introduced through the feed opening 4 can be easily introduced into the feeder 20 through the gap formed between the protective cover 50 and the edge 42 in the feed plate 40.

As it turned out FIG. 8 results, the protective cover 50 is also designed so that it has a polygonal circumference. In the exemplary embodiment shown, the protective cover 50 has seven corners, and thus a different number of corners, than the feed opening 4. In particular, here the feed opening 4 has four corners, whereas the protective cover 50 has seven corners.

The protective cover 50 is also wider in the area farther away from the operator where it can potentially engage at a shallower angle through the feed opening 4. Accordingly, here the overlap between the feed opening 4 and the protective cover 50 is significantly larger, so that an inadvertent intervention of an operator, for example, if it slips and passes with an arm through the feed opening 4, is sufficient so that contact with the crushing device 22 is excluded ,

Accordingly, the shown geometry of the feed opening 4 in combination with the protective cover 50 achieves a high safety standard by means of which it can be prevented that an operator can intentionally or unintentionally intervene in the current comminution device 22.

In the FIGS. 9 to 12 a processing apparatus 1 is shown in a second embodiment. The processing apparatus 1 itself is basically constructed as that shown in the first embodiment. Again, an operation of the processing device 1 is possible only when the machine cover 12 is closed. Furthermore, a task plate 40 is provided, which in turn has an inclined to the feed opening 4 embodiment, in which case only a wedge-shaped configuration is provided. Accordingly, although an overflow of discontinued on the task plate 40 kitchen waste is avoided and this moves due to the wedge effect in the direction of the feed opening 4, a complete clearing of the task plate 40 alone, for example, by the vibrations of the processing device 1, but does not take place here.

The feed opening 4 is again polygonal, in particular in the form of a kite quadrilateral, and correspondingly has the acute angles described in the previous exemplary embodiment, which allow trapping of the extremities of an operator.

In FIG. 10 For example, in the second embodiment, the processing apparatus 1 is shown with the machine cover open and it can be seen that the protective cover 50 is similarly held on the machine cover 12 via support struts 54. The protective cover 50 is provided with a wedge shape, substantially opposite to the task plate 40, so that kitchen waste applied to the protective cover 50 drains into the feeder 20.

The protective cover 50, in turn, overlaps the supply port 4 so as to reliably provide engagement protection. The in the FIGS. 9 to 12 embodiment shown also represents a reliable engagement protection, but is easier to manufacture from the manufacture, since both the task plate 40 and the protective cover 50 each consist of only two individual segments. As a result, manufacturing costs can be reduced.

In the embodiment shown, it is in the in the FIGS. 9 to 12 In the embodiment shown, a narrower processing device 1, which accordingly also has a narrower feeding device 20, such that an operator who engages through the feed opening 4, is guided by the protective cover 50 in the side regions directly to the outer wall of the feeding device 20. In other words, a limb of an operator, which engages through the feed opening 4 in the lateral direction, can be inserted a little way, but then immediately stopped by the wall of the feeder 20.

Towards the operator, the extremity of the operator is immediately pinched by the acute angle at the angle 420, so that inadvertent intervention does not take place here.

The rear end of the protective cover 50 in the side facing away from the operator is further dimensioned so that an operator, even if he should adversely engage through the feed opening 4, is also stopped directly on the wall of the feed opening 20 and, accordingly, an intervention in the crushing device 22nd in operation is not possible.

Where applicable, all individual features illustrated in the individual embodiments may be combined and / or interchanged without departing from the scope of the invention.
