Description

Background of the invention

The invention relates to a food processor for producing rope-shaped pasta, in particular noodles, with a conveying unit which conveys the dough mass to be formed in the direction of a perforation unit provided with openings, according to the preamble of claim 1.

State of the art

A food processor of the type mentioned is from the DE 38 22 301 A1 known. The pasta machine described there consists of a motor housing for the electric drive, which is seated on a foot and carries on its upper side a receptacle with a kneading. On the motor housing laterally projecting a hollow cylindrical housing part is formed with an outlet opening, which receives a noodle dough in the direction of the outlet opening promoting screw. In the lateral outlet opening provided with a number of openings molding plate can be used, which is held by a union nut on the hollow cylindrical housing part. After loosening the nut, the mold disc can be removed and replaced by one of several other shaped discs with deviating breakthrough pattern, which are kept in a carousel in the foot of the motor housing. To select the desired shape of the disc, the carousel is rotated until each provided with a cap tray is accessible to the desired shape disc.

Another device for extruding pasta is in the DE 27 18 879 A1 described. This pasta machine also has an assembly which serves to prepare the dough by mixing and kneading the dough-forming constituents and consists of a container with rotating blades. These promote the dough through an opening made in the container bottom after completion of the dough preparation in the direction of a Extrudierblocks. This consists of a hollow cylinder, in which a dough in the direction of a drawing iron promoting screw is arranged. The screw presses the dough through the perforated iron, in which the dough is molded and subsequently exits the pasta machine laterally.

These prior art pasta machines have the disadvantage that an interruption of the pasta production and an opening of the housing are required for a change of the breakdown pattern, which is associated with a time and cleaning effort. In addition, the molded dough, after exiting from the molding disc or drawing iron, following gravity, deflected downwards, whereby the dough strands can change their shape and stick together.

A differently designed in terms of design and function device for the production of noodles is in the DE 89 14 789 U1 disclosed. By means of this pasta machine short elongated pasta pieces, such as spaetzle, produced. The previously processed elsewhere dough is, for example by means of a screw, fed into a channel of the device and exits in the region of a provided with horizontal slots aperture from this. Rotatable behind the slots and parallel to their transverse extent is a roller equipped with radial knives which grips the dough and cuts it into pieces of pasta whose length corresponds approximately to the transverse extent of the slots. The sharp edges of the knife are aligned in such a way that they tear off the scraped-off dough pieces irregularly and thus form the typical surface texture of spaetzle. The roller is pivotally mounted on arms and can be swung up for cleaning and for changing the blades or the aperture.

This device is not suitable for producing pasta of greater length, for example spaghetti.

The DE 2231738 A teaches a device for dispensing and distributing foodstuffs such as dough or the like. A tube is telescopically attached to a tube, which can open or close holes in the tube by being able to be turned relative to the tube. The openings are respectively arranged on the circumferential line of the tube and the sleeve.

Out CH 139465 A is a shredder known for domestic use. If you want to use the machine as a fruit press, a press and screw conveyor, for example, by a bayonet lock on the edge of the wreath enclosing the outlet are easily releasably attached.

The DE 354140 A discloses a usable as a dough syrup meat grinder with screw conveyor. Instead of the cutting tools for meat, a shaped disc provided with various types of holes may be fitted to the end of the screw conveyor axis, with a cover plate provided with a single window which is adjustable with respect to the forming disc for exposing a group of holes.

From the US 2,298,644 A is a device known for the production of food paste articles. After passing through a vacuum chamber, the food paste is released through a forming plate to the outside.

The problem underlying the invention

The invention has for its object to further develop a generic food processor so that a change in the cross section of the formed dough strands simplified and their further handling can be improved.

Inventive solution

The object underlying the invention is in a food processor of the type mentioned for producing stranded pasta, especially noodles, with a conveyor unit, which promotes the auszuformende dough mass in the direction of an apertured Ausformeinheit, in which the shape of the apertures of the Ausformeinheit is adjustable and the molded dough mass emerges in the direction of gravity from the apertures of the Ausformeinheit, the Ausformeinheit having a first arrangement of apertures and a second array of apertures, which can be brought adjustable with the first arrangement of apertures in at least partial coverage and the first arrangement of openings in the lower radial surface of a first tubular body connected to the conveying unit and the second conveying unit are embedded in the radial surface of a further tubular body, which rotatable coaxially with the first tubular body to this is arranged, solved by the fact that the first openings can be selectively brought into overlap with groups of differently shaped second openings. This makes it possible to change the food processor in a simple manner, possibly even during operation, to the shape of a different dough strand or to correct the cross section of the dough strand, if the default by changing the dough consistency or the like should prove to be incorrect or not optimal. Thus, cross sections of completely different shape and dimensioning can be realized.

Preferably, the further tubular body is releasably secured to the first tubular body of the Ausformeinheit in the manner of a bayonet closure. Such closures can accommodate large loads and yet are easy to attach and detach.

The handling of the food processor according to the invention is simplified by these measures so that even the layman can easily manage the preparation of the pasta.

Preferred embodiment of the invention

Advantageous embodiments or developments, which can be used individually or in combination with each other, are the subject of the dependent claims. Advantageously, the conveyor unit of the food processor is equipped with a screw conveyor. Augers can be ideally suited for conveying doughy masses with appropriate design. Furthermore, the previously prepared dough can be further homogenized during screw feeding, which improves the consistency of the dough. In addition, the required for the promotion of the dough speed and the torque of the screw conveyor preferably corresponds substantially to the speed of a Knethakens, which is used for the dough processing. The drive device of the food processor can therefore possibly even be used without further reduction for the drive of the screw conveyor. Furthermore, a screw conveyor after removal from the conveyor unit can be cleaned relatively easily.

Preferably, the delivery unit is tube-like and laterally attachable to the housing of the food processor, for example by screwing to a correspondingly shaped receptacle on the housing side of the food processor. The conveyor unit can thereby be easily removed when not in use. In addition, the pulling of the screw conveyor for cleaning purposes is facilitated.

The Ausformeinheit is preferably arranged at the housing distal end of the housing projecting from the food processor conveyor unit. This makes it possible to provide a relatively large water bath under the Ausformeinheit and place the food processor at a sufficient distance from the stove top.

With particular advantage, the setting of breakthroughs in at least partial coverage, for example, take place in that the degree of overlap between the first and second arrangement of openings is provided changeable. If the openings are formed, for example, circular with the same diameter, the dough strands emerging from the Ausformeinheit have the largest possible coverage of the openings a relatively large, circular cross-section, which decreases in an lenticular shape in an adjustment. As a result, an adaptation of the shape of the consistency of the dough is possible during operation.

The cross section of the first openings is advantageously dimensioned such that it corresponds at least to the largest selectable cross sections of the second openings.

Constructively, a food processor with all the advantages of this invention can be particularly easily run when the first arrangement of openings in the lower radial surface. a first pipe body connected to the conveying unit and the second arrangement of openings are embedded in the radial surface of a further tubular body, which is arranged coaxially to the first tubular body rotatable and sealed on this. By simply turning the further, preferably outer tubular body relative to the first, preferably inner tubular body, both a change in the degree of overlap and a selection of different overlapping breakthroughs can be realized without much effort. The handling can be further simplified by a scaling applied in the visible transition region between the first and further tubular bodies.

Constructively particularly favorable is a food processor, in which the first tubular body of the Ausformeinheit is integrally formed with the tubular conveyor unit. The conveyor unit in question can be manufactured without problems, for example by injection molding of plastic including all connection and sealing devices to the housing and further tubular body. The one-piece design also seams between conveyor unit and Ausformeinheit be avoided, which can cause an increased cleaning effort.

Furthermore, it can preferably be provided that the further tubular body is formed on its housing-distal end face cap-like closed. The further tubular body thus seals the delivery unit in a simple manner from the front side. In addition, the screw conveyor is accessible in a hollow cylindrical conveyor unit after merely removing the other tubular body for the purpose of cleaning or replacement.

The attachment of the further tubular body to the first tubular body of the Ausformeinheit is formed according to a further advantageous embodiment of the invention in the manner of a bayonet closure.

The further tubular body can be fixed by the bayonet lock preferably in different rotational positions on the first tubular body, whereby in particular the adjustment of the Ausformeinheit by selecting differently shaped apertures in a structurally simple manner is possible.

A suitable bayonet lock advantageously has hook-shaped recesses on the housing-side edge of the further tubular body and at least one pin projecting radially out of the first tubular body, which pins can each be inserted into a selectable recess. A production by means of injection molding of plastic allows this design easily. In addition, such a bayonet lock can be easily cleaned and operated intuitively.

According to another preferred embodiment of the invention, the first tubular body in its rotational position relative to the further tubular body is infinitely adjustable by a certain angle, for example using an adjusting device equipped with a screw. As a result, a change in the exit surface in the Ausformeinheit and thus also the pressure in the delivery unit is variable during operation, for example, to compensate for fluctuations in the quality of dough.

Detailed description of the invention with reference to two embodiments

In the 1 illustrated food processor 1 consists of a housing 2 from which an electric drive device is received. In the area of an unshown, upwardly projecting shaft, various tools and containers can be placed on the food processor 1 put on and driven by this.

From the upper part of the housing 2 protrudes a tubular conveyor unit 3 projecting laterally for the dough promotion, which by a in the housing-side end 4 the conveyor unit 3 radially opening from above funnel 5 with the dough 6 is fed. In the conveyor unit 3 is a screw conveyor 7 around a horizontal axis 8th rotatably arranged, which with their turns 9 from the funnel 5 inflowing dough 6 and toward the end of the housing 10 the conveyor unit 3 pushes. The screw conveyor 3 gets in from the case 2 located drive means driven by using an angular gear. The housing remote end 10 the conveyor unit 3 goes into the adjustable Ausformeinheit 11 over, in which the dough mass 6 is deflected downwards and through radially arranged openings 12 through as a variety of dough strands 13 exiting in the direction of gravity. The for deflecting and squeezing the dough 6 required pressure is from the screw conveyor 3 generated.

Below the molding unit 11 is one in a saucepan 14 located water bath 15 provided, which means of a stove 16 is heated. The from the breakthroughs 12 the Ausformeinheit 11 emerging dough strands 13 sink in a straight line, following gravity without deflection, into the water bath 15 down and are cooked there.

How out 2 can be seen, is the conveyor unit 3 tubular and formed at its end near the housing 4 with a one-piece, knurled collar 17 provided, which for manual screwing on the conveyor unit 3 to a corresponding thread on the radial surface of the housing 2 the food processor 1 serves. Beyond the collar 17 is located radially above the confluence 18 for the funnel 5 in the conveyor unit 3 intended.

At the end of her housing 10 the conveyor unit is running 3 in one piece into a first tubular body 19 the Ausformeinheit 11 one. On the first, inner tube body 19 is another, external tubular body 20 placed coaxially and sealingly, the housing-front side 21 Cap-like is closed. The further tubular body 20 is at his the housing 2 facing end by means of a bayonet lock 22 detachable and adjustable on the first tubular body 19 established. The first pipe body 19 has for this purpose a radially upwardly projecting pin 23 on, which optionally in one of three hook-shaped recesses 24.1 to 24.3 can be inserted and locked in this. The insertion of the recesses 24.1 to 24.3 takes place in the axial direction of the tubular body 20 (Arrow A), while the locking by its rotation relative to the tubular body 19 in the direction of arrow B. Unlocking and releasing the other tubular body 20 is done analogously by opposing movements. By optional insertion of the pen 23 in one of the three recesses 24.1 to 24.3 can the outer tube body 20 relative to the inner tubular body 19 be set in three different rotational positions. The other, outer tubular body 20 is at his in 3 shown lower radial surface, so the recesses 24.1 to 24.3 opposite, with groups of differently shaped breakthroughs 12.1 . 12.2 provided, which have different diameters and depending on the selected rotational position of the outer tubular body 20 relative to the inner tubular body 19 optionally in overlap with congruent recesses 12.1 . 12.2 at the lower radial surface of the first inner tubular body 19 can be brought ( 4 and 5 ). The forming unit 11 from the screw conveyor 3 supplied dough mass 6 can only by such breakthroughs 12.1 . 12.1 'or 12.2 . 12.2 ' down in the direction of the water bath 15 to emerge, which were brought into overlap.

For cleaning, the conveyor unit 3 and the Ausformeinheit 11 from the case 2 unscrewed and the only form-fitting, for example, by a square, sitting on the reversing conveyor screw conveyor 3 be pulled out. As conveyor unit 3 and the Ausformeinheit 11 In the exemplary embodiment taper slightly conically towards the outside, the extraction of the screw conveyor must 3 to the rear, so in the direction of arrow A done. After removing the cap-like tubular body 20 All components can be easily cleaned manually or using a dishwasher.

In the execution after 6 are the inner, first tubular body 19 and the outer, further tubular body 20 the Ausformeinheit 11 each other by means of an adjusting device 25 infinitely adjustable by a small angle. The adjusting device 25 consists of a first, from the outer tubular body 20 cantilevered tab 26 and a second, from the inner tubular body 19 protruding tab 27 by a set screw 28 towards each other or away from each other are adjustable. While in a first setting ( 6a ) the circular breakthroughs 12.1 . 12.1 'are the same diameter in exact coverage, they are in position after 6b only partially covered.

With complete coverage of the breakthroughs 12.1 . 12.1 'is the dough strand 13 in cross section, as out 7a can be seen, also circular, while its cross section when adjusting the molding device 11 in the position after 6b lenticular constricted ( 7b ). Adjusting the molding unit 11 can while operating the food processor 1 to adapt to changing dough consistency or the like. A complete closure of the Ausformeinheit 11 should be used to avoid an undesirable increase in pressure in the liquid end 3 be preferably avoided by limiting the adjustment.
