Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of manufacturing a perforated or punched cut snack as described in the main claims, and an apparatus for carrying out this method. . More specifically, the present invention is a one- or multi-layered dough made of a grain material such as wheat flour.
The present invention relates to a method and an apparatus for manufacturing a two-dimensional or three-dimensional piece having a desired shape and design from a (dough).

[0002]

2. Description of the Prior Art Cut snacks that are perforated or punched are well known. They are formed from cereal material such as flour, which may or may not be pre-cooked, and may be shaped into a wide variety of shapes, with or without internal perforations. These products are produced, for example, from rolled or extruded dough layers. These layers are cut after an optional drying step. Two cutting operations are required to manufacture a figure such as a hole inside the outer circumference. That is, it is a first work for making a hole inside and a second work for cutting the outer circumference. This results in the need to use very large and heavy moulds with two rows of punches.

[0003]

The heavy weight of the mold and the other movable members connected to the mold impede the fast reciprocating motion required to obtain the required output. Also, in this method the dough sheet must be stopped at the time of cutting. Therefore, this method requires reciprocating motion, which is another limitation for achieving high speed.

In addition, this method does not overcome the problems that result from the tackiness of the material, which makes it easier for the material to adhere to the mold or countermould. Therefore, this method is only applicable to materials that are at least partially dried and have good mechanical rigidity.
The difficulty with this well-known method to move the dough layer exactly and consistently leads to some inaccuracy in the positioning of the inner holes with respect to the outer circumference of the snack, thus resulting in poor shape. Become.

Then, for the same reason, by making a given distance between one figure and the next,
It is necessary to prevent supply such that one figure overlaps another figure. As a result, the chips (o
ffcut) will be greatly increased, and related problems of chip disposal will be increased. A system using a roller is also known. However, since these systems use rollers to form the dough layer and these rollers feed directly into the dough, the application of the system is to produce products that can be produced using this method. Will be limited to.

US Pat. No. 4,348,166 discloses a dough molding system that overcomes the problem of sheets sticking to the outer periphery of a molding roller. In this case, compressed air is applied inside the counter-roll.
This is because the sticky sheet easily adheres to the counter roller and does not adhere to the cutting roller. In other cases rollers are used to form a non-tacky dough layer. Therefore, the problem of controlling adhesion and removing chips and the product itself has not been solved.

European Patent 0256301 describes the shaping of the dough layer and does not deal with cutting. Therefore, the formed dough layer is not cut. This is because the molding in this case is performed by utilizing pressure and temperature.

EP 0294125 relates to a suitable and standard arrangement for the uniform cooking of baked products (biscuits and crackers) in an oven. Although this cutter device is not concerned with its properties, a conveyor belt for transporting these products into the oven in the required manner is important. There is no description in this specification of how to make the inner holes formed in the snack, nor how to separate the chips from the snack, and to remove the chips. There is no mention of how to remove it from the conveyor belt.

US Pat. No. 3,171,315 relates to manufacturing items such as signs and designs on the surface of a pie that has already been placed on the feeder conveyor at preset, regular intervals.

As described above, the above-mentioned conventional specification has nothing to do with the problem here, neither in itself nor in a combination thereof. Furthermore, the conventional methods do not solve the problem of engaging snacks and chips and carrying them to different preset locations, which allows them to be removed in different directions.

[0011]

Applicants have designed, tested, and instrumented the present invention to overcome the problems of the prior art devices and to manufacture punched and punched cut snacks. did. The invention is described and characterized in each main claim, while the dependent claims describe various variations of the concept of the main claim. It is an object of the invention to provide a new method for producing punched and punched cut snacks. In the method according to the invention, it is possible to separate cut snacks that are perforated or punched from the chips and scraps of the dough layer. The chips and scrap are collected to form the next sheet of dough.

Another object of the invention is to provide an apparatus using this method. In the present invention, whether or not cooked in advance, a dough layer made of a grain material such as wheat flour is produced by an extrusion molding step and a rolling step performed subsequently, and at least one cutter roller is used. Be collaborated with. Above the cutter roller is a hollow outer contouring punch having the desired shape and design. In the present invention, the cut snack thus produced can be retained on the cutter roller in a hollow outer contouring punch. Snacks cut by these punches are held on the cutter roller in the punch while the cutter roller is rotated through an angle due to the negative pressure acting on the inner periphery of the hollow outer contouring punch. .

In another embodiment, the snacks cut by these punches are pulled toward the inner ends of the punches by the negative pressure exerted on the inner periphery of the hollow outer contouring punch. In the present invention, the inner end is provided with a suitable recess, which is permanently stamped to imprint the recess on the snack to produce a three-dimensional product. To remove the cut snack from the cooperating hollow outer contouring punch, the cutter roller cooperates with the extractor. The surface of the extractor is strongly affected by the negative pressure. These extractors have extractor rollers or extractor conveyor belts. However, the peripheral speed of the cutter roller equipped with a punch and smooth double reversal (contr
a-rotating) An extractor is not required if a suitable relative speed is maintained with respect to the speed of the rollers or the opposing conveyor belt.

In the present invention, the cutter roller is not subject to its own suction in the hollow outer contouring punch in the area cooperating with the extractor. In the present invention, the extractor has a discharge area downstream of the engagement area of the cutter roller. The surface of the extractor is not subjected to negative pressure in the discharge area. Its purpose is to allow the snack to be delivered to the appropriate area. This cancels the pulling force of the snack on the outer surface of the extractor and allows the cut snack to be pulled apart.

In another embodiment, the discharge area of the extractor is maintained under pressure and outward thrust is applied to the cut snack located on its outer surface to facilitate removal of the snack. There is. This area cooperates with an optional extractor. The extractor holds the cut snack while rotating and places it in the required position on the conveyor system. The conveyor device conveys the snacks to the subsequent drying and flying process.

In the first embodiment, the pressing force of the dough layer against the hollow outer contouring punch is generated by pressing the cutter roller against a smooth counter-rotating roller. In this case, it is preferable that the dough layer is moved in the vertical direction by using rollers arranged side by side so that their rotation axes are located in the horizontal plane.

In another embodiment, pressing the dough layer against the hollow outer contouring punch is accomplished by pressing cutter rollers against the opposing conveyor belts. In the present invention, by adjusting the cutting pressure, it is possible to produce a snack with the correct cutting outer contour regardless of the type of dough. In order to produce holes of arbitrary shape inside the outer circumference of the snack, the invention provides a first cutter roller upstream of the roller which cuts the outer contour. The first cutter roller is equipped with a punch for punching to manufacture the inner hole. These piercing punches are arranged on the first cutter roller in a manner compatible with the hollow outer contouring punches arranged on the cutter roller.

The first cutter roller having the punch for punching according to the present invention and the cutter roller having the hollow outer contour forming punch operate in synchronization with each other. This is because these cutter rollers are mechanically interconnected by a mechanism that can adjust the synchronization itself. In order to eliminate scrap generated by the punch for making the inner holes, the first cutter roller has a hollow inside, and on the surface thereof, there is a through hole aligned with each punch. Is provided. The scrap produced by the cutting of the inner hole produced by the punch for punching is collected inside the first cutter roller through these through holes by successive compression and is passed through the extruder. To be recovered inside.

In another embodiment, the scrap originating from the inner holes and collected inside the first cutter roller is used to produce a large number of small snacks. In the present invention, the internal cavity of the first cutter roller is maintained at a negative pressure, for example by means of a suitable suction device, to help remove scrap originating from the inner bore. Alternatively, a system may be used that uses compressed air to remove scrap from the inner holes. The compressed air in this case acts along a predetermined circular sector of the first cutter roller. The circular sector is arranged to reject internal scrap onto the reject conveyor system. The detachment of the snack from the cutter roller can also be successfully accomplished by compressed air acting on a preset circular sector of the cutter roller.

In another embodiment, the external and internal cutting of the perforated snack is done in one step. In this case, the cutter roller mounts a cooperating punch for punching inside the hollow outer contouring punch. Also in this embodiment, the punch for punching is connected to the inside of the cutter roller to remove the scrap inside. The dough scrap produced by the cutting performed by the hollow outer contouring punch is shredded and sent to an extruder for recovery.

In order to produce a cut snack having at least one surface with recesses or protrusions, such as a grill, according to the invention a smooth opposing roller or a punching roller cooperating with an opposing conveyor belt. Is provided. The punching roller forms a grill by applying a deformation on the dough layer, i.e. without removing material from the dough layer.

In another embodiment, the dough layer cooperates with two counter rotating punch rollers to perform this task. After punching, the dough layer is made to cooperate with a cutter roller carrying a hollow outer contouring punch for cutting the outer contour of the snack. These snacks with at least one punched surface also have holes inside their outer contour.

In yet another embodiment, two punched or unpunched layers are stacked parallel to each other and joined together along the outer circumference by cooperating with a cutter roller. It is designed to produce two layers of snacks. These two-layer snacks also have holes inside and at least one of their surfaces is punched.

In yet another embodiment, two snacks having different outer contours are joined together to form a two layer snack. In this case, a two-layer snack is manufactured by stacking a single snack placed on top of two counter-rotating cutter rollers on top of each other. These single snacks are joined together along any location around them. The accompanying drawings illustrate embodiments of the present invention, but do not limit the invention.
