Description

processing device

Technical area

The present invention relates to a processing device for processing kitchen waste, in particular for processing organic kitchen waste in large kitchens, canteens, hotels,

Communal catering facilities as well as in the gastronomy.

State of the art Organic kitchen waste in the form of food waste and equipment waste, for example, fall into

Commercial kitchens, canteens, hotels, communal catering facilities as well as in the catering trade in large quantities daily. 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, when taking back plates and trays from the respective guests,

Employees or patients before rinsing these plates or trays. 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 fall large quantities of

On food waste.

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

by means of a crushing device in the form of a grinder, partially with the addition of

Water, are crushed so that they can then be pumped in a largely homogenized form in appropriate storage tanks. From these storage tanks, the then largely homogenized biomass by means of a transport vehicle to a biogas plant

transported in which the biomass is fermented without further treatment, wherein the in the

Fermentation resulting fermentation gases, especially methane gas, for the production of 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 DE 20 201 1 050 658 U1 a disposal device for organic kitchen waste is known, in which the work 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, a processing apparatus for processing kitchen waste

proposed, comprising a crushing device for comminuting the kitchen waste, a

Feeding device for feeding uncrushed kitchen waste to the crushing device, and a covering the feeding device at least during operation of the crushing device

Engine cover. According to the invention, the machine cover has a feed opening having an engagement protection for feeding uncut kitchen waste into the feed device

on.

By providing the feed opening, the feed device can be charged even during operation of the comminution device when the machine cover is closed

Crushing device take place. The intervention protection at the same time provides effective protection of the operator. This makes it possible to efficiently feed even large quantities of

Do 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 feed opening of the machine cover is hampered by the Eingreifschutz so that contact with the

Crushing device and thus injury to the operator are excluded.

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 scavenge the kitchen waste into the crusher can be minimized or it can be due to the use of water for flooding the uncut

Kitchen waste in the crushing device are completely dispensed with. In other words, that is

Feed opening preferably substantially vertically above the crushing device, which is provided for example in the form of a grinder, provided in the machine cover. The engagement protection preferably has a feed opening which at least partially overlaps

Protective cover, 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. When closed

Machine cover is thus the protective cover below the feed opening, so 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 pointed in the direction of the feed opening

tapered shape, preferably a conical shape, one of at least two segments

composite form or a pyramidal shape. So can kitchen waste that on the

Impact cover, simply drain down, without an operator here

would have to postpone. On the basis of this embodiment, the work safety

continue to increase, as an operator does not feel the need to postpone the

Kitchen waste to reach 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.

To increase the work safety already by the shape of the feed opening, the

Feed opening in the form of a planar polygon, preferably at least one point

Angular polygonal shape. The limbs of one are caught in the acute angles

Operator when it engages through the feed opening, so that too deep insertion of the

Limb is blocked in the feed opening in this way. This will increase the risk of

Intervention in the crushing device further reduced.

The feed opening may preferably have the shape of a planar quadrilateral, especially

preferably a kite quadrilateral, a deltoid or a rhombus. By in these forms

present acute angle can be a reliable braking, jamming or blocking 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 can be so different sizes

Overlap areas are formed, which accordingly according to anticipated

Einreifrichtung a good occupational safety with good Einbringverhalten the

Kitchen waste to be trained.

In order to enable a simple introduction of large amounts of kitchen waste in the processing device, a task plate for giving up the kitchen waste in the

Machine cover provided and the feed opening is arranged in the task plate.

Preferably, the feed plate is inclined towards the feed opening and particularly preferably has the

The shape of an inverted truncated pyramid, a funnel or one of at least two

Segments composite form. The intervention protection further advantageously has at least one in the plane of the

Machine cover extending transverse strut, which passes through the feed opening and which preferably forms 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 with the

Feeding device cooperates so that an intervention of an operator in the

Crushing 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.

FIGS. 1 to 8 show a processing device 1 in a first exemplary embodiment in different perspectives and in a sectional representation.

FIG. 1 shows, in a schematic perspective view, a processing device 1 which is used for processing and disposing of organic kitchen waste, in particular of

Food waste or from equipment waste serves. Such a processing device 1 is

Usually provided in a large kitchen, a canteen or other food processing operation to process, for example, the accruing organic kitchen waste that 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 device 1 is arranged either in the region of the set-up stations in which organic food is pretreated-for example peeled-or in the region of the rinsing stations in which trays and plates are emptied of food waste, in order to process the respectively accumulating organic waste. The processing apparatus 1 comprises a base housing 10 and a machine cover 12, which, as can be seen for example from FIG. 2, can be opened to form a funnel-shaped feeding device 20, which ultimately turns the organic kitchen waste into a

Crushing device 22, which is schematically indicated, for example, in the sectional view in Figure 5, supply. In the comminution device 22, the organic wastes are ground into a pulp that is easy to pump, which can then be disposed of.

In FIGS. 1 to 8, the processing device 1 is shown in different views. For example, in FIG. 2, 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 portion 120 is provided, which forms a sealing edge 122 which engages with a corresponding seal receptacle 1 12 on the base housing 10 can be brought. At the

Sealing edge 122 and / or the seal holder 1 12 may be an elastomeric seal is 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 entering the feeder 20 and, in particular, the machine during operation

Crushing device 22 engages. 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 because the total height of the processing device 1 is designed so that it can be easily reached by an operator, and in particular the upper edge of the machine cover 12 on the usually located in kitchens

Working height is between 850 and 950 mm. Here, the danger is particularly great that by slipping or other uncontrolled unintentional movements, the extremities of an operator can get into 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 allows a start of the crushing device 22 only if 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, as can be seen for example from FIG. 5, provided in the region of the connection of the machine cover 12 to 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 is apparent, for example, from the schematic sectional illustration in FIG. 5, 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 can also be kept in the open position shown, for example, in FIGS. 2 to 4 in order, for example, to carry out cleaning and maintenance work, or to release possibly occurring blockages in the processing machine.

In order to enable a continuous feeding of the processing device 1 with substances to be processed, such as kitchen waste, a feed opening 4 is provided in the machine cover 12, via which unzerkleinerte kitchen waste can be entered into the feeder 20 and thus ultimately into the crushing device 22. The feed opening 4 is in the embodiment shown in a central region of

Machine cover 12 is arranged and accordingly allows the comfortable introduction of kitchen waste in the feeder 20. For supplying the kitchen waste through the

Feed opening 4 in the feeder 20, it is not necessary to open the machine cover 12, so that a feed can take place during operation of the crushing device 22.

In order to enable a simple and overflow-free feeding of kitchen waste into the feed opening 4, a feed 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 particularly accurately in the feed opening 4. The task plate 40, in which also the feed opening 4 is arranged, is slightly funnel-shaped. In the shown

Embodiment, the task plate 40 of the machine cover 12 comprises five segments, which form a slope of the task plate 40 to the feed opening 4, so that

Kitchen waste, which does not reach directly into the feed opening 4, can flow into the feed opening 4, or at least can not flow away beyond the machine cover 12 to the outside. This feeding can also take place without the addition of further water, so that the

Water consumption of the proposed processing device 1 is very low, which is reflected in a cost savings, since the additional volume of water does not have to be disposed of. To an intervention of an operator through the feed opening 4 into the

To prevent 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 on the inside of the

Machine cover 12, so on the feeder 20 and the

Crushing device 22 facing side of the machine cover 12, is arranged. The protective cover 50 is, as is apparent from Figures 2 to 5, so spaced from the feed opening 4 arranged that between the feed opening 4 forming edges 42 in the feed plate 40 of the machine cover 12 and the

Protective cover 50 is a sufficiently extensive gap through which the kitchen waste can get into the feeder 20.

In the first embodiment shown in FIGS. 1 to 8, as is apparent directly from the figures, and in particular from FIG. 4, the protective cover 50 is designed such that it completely overlaps the feed opening 4 in the plane of the machine cover 12. In other words, the edges 42 of the feed opening 4 are in a direct plan view of the

Protective cover 50. In the embodiment shown in Figures 1 to 8 is the

Protective cover 50 has a heptagonal design and in particular has six triangular segments 500, which are assembled in a pyramidal shape so that kitchen waste, which reach through the feed opening 4 on the protective cover 50, depending on the impact on the protective cover 50 to one side or even in all directions out into the feeder 20 and on short path into the crushing device 22 arrive. The protective cover 50 is formed correspondingly pointed to the feed opening 4, as is apparent directly from the side view in Figure 3 and the sectional view of Figure 5, for example.

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 through the feed opening 4 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 automatically blocked.

The engagement protection 5 comprises, as a further element, a transverse strut 52 which extends in the

Substantially in the plane of the machine cover 12 extends. 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.

Furthermore, the engagement protection comprises 5 holding struts 54, which primarily for holding the

Protective cover 50 are provided on the machine cover 12 at the predetermined distance. The holding struts 54 extend from the machine cover 12 and at the same time also serve to divide the feed path through the feed opening 4 even smaller, so that an intervention of an operator in the comminution device 22 is prevented here as well. On the transverse strut 52 and a support strut 54 may be arranged so that the

Cross strut 52 may have the property of a support strut, as it carries a support strut 54 for holding the protective cover 50. In FIGS. 7 and 8, the machine cover 12 is shown once more alone and in perspective views in order to illustrate the interaction between the design of the feed opening 4 and the engagement protection 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 illustrated for example in FIGS. 7 and 8.

In the area of the angle 429, which represents the angle farthest 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 can be seen immediately from FIG. 5, for example. 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 is apparent from Fig. 8, the protective cover 50 is also made to have 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.

FIGS. 9 to 12 show a processing device 1 in a second exemplary 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, an overflow of abandoned on the feed plate 40 kitchen waste is avoided and this due to the

Wedge effect moves 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, the processing apparatus 1 is shown with the machine cover open in the second embodiment, 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 embodiment shown in FIGS. 9 to 12 also provides reliable engagement protection, but is simpler to manufacture since both the application plate 40 and the protective cover 50 are each made of only two

Consist of individual segments. As a result, manufacturing costs can be reduced.

In the exemplary embodiment shown, the embodiment shown in FIGS. 9 to 12 is a narrow processing device 1, which accordingly also has a narrower feeding device 20, such that an operator who engages through the feed opening 4 passes through the protective cover 50 is conducted in the side areas directly to the outer wall of the feeder 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 operator facing away from the side is further dimensioned so that an operator, even if he should inconveniently 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. LIST OF REFERENCES
