Description

Animal feed and method and machine for its production

The invention relates to a feed as well as a method and a machine for its production according to the preambles of claims 1, 8 and 14, respectively.

According to DE 3301215 A1, a method and a device for producing a feed is known, wherein the respective inert substances are loaded with fat by a spraying operation and these loaded inert substances are mixed with a solid feed in a feed mixer. According to DE 37 01 861 A1, a method for producing a feed for dogs in particular is proposed, granular dry constituents and a hot binder solution being mixed intimately. This feed mixture is shaped, portioned, dried and cooled, the feed being provided in the form of bars pressed in a portioning machine and then dried in an oven.

The invention is concerned with the problem of creating a method and a machine for producing a feed for dogs in particular, by means of which a product which is simple to produce and of which the structure can be administered as a reward as a reward, the shape and consistency of which are both playful to use is provided a leader is suitable as well as animal-friendly bite resistance with low nutritional value.

The feed according to the invention is designed as a reward article, which is produced as an individually manageable portion body. This portion body has animal-friendly baked goods as the core part, which can be replaced by at least one soapy closed and essentially defining a spherical circumferential contour covering layer is encased. With this product, which has a particularly low nutritional value, small portion bodies are provided for a large number of rewarding actions when playing with a dog, the nutritional-physiological effect of which is harmless even with a large number of administrations. The portion or ball body having a largely arbitrary diameter can be handled individually and has a consistency that remains sufficiently stable even when held in the hand of the driver for a long time, but at the same time is sufficiently compliant in the event of a bite by the animal, so that the aromatic cover layer and the inner core baked goods are released after the reward campaign.

In the method for producing the animal feed, a machine system is used in which a pressing device is used to form the core body from a pasta. In the mold troughs of the pressing device, the respective dough bodies are shaped largely round, so that during the subsequent baking process the dough bodies are deformed by the associated blowing effect and an essentially oval or spherical contour of the baked goods is achieved.

The core parts, which are now available as baked goods, can be inserted into a coating device of the machine system, using a simply constructed rotary boiler. Whose arched contoured bottom part takes the baked core parts and a liquid, heated coating agent in the form of a by animal-friendly flavors u. Like. flavored fat solution. Through an inclination and rotation of the rotary boiler, the core parts are rotated and starting from the bottom part within the Rotary boiler shifted so that the core parts are permanently rolled in the area of the boiler wall. As a result, a fat coating is formed over the core parts. At the same time, cooling air is blown into the rotary boiler during this rolling process, so that the core parts which are in each case above and already coated are exposed to an air flow. The fat layer hardening on the outside penetrates the rough surface of the baked goods core part on the inside and is positively connected to it.

After this coating process, the now double-layer portion body is kept in a waiting phase and the covering layer forming a closed peripheral contour around the baked goods is thus largely cured. In a subsequent second coating unit, an additional coloring and / or glossy layer can now be applied to the cover layer, similar to the first process step described above.

An essentially taste-neutral substance in liquid form is used for this application of the gloss layer, this consisting in particular of a powder dissolved in water. For the coating process within the rotary kettle, only a small amount of dry air is blown in during its rotation, so that the water portion of the substance as a gloss agent on the portion body evaporates and, with little effort, a sufficiently solid and closed top layer is achieved for the intended use.

Further details and advantageous embodiments of the invention result from the following description in conjunction with the drawing, in which two exemplary embodiments of the spherical feed, a schematic The process sequence and the machine system according to the invention with the coating devices are schematically illustrated. The drawing shows:

1 is a cross-sectional view of the feed product having a baked goods core part and a cover layer in its conceivable product size,

2 is an enlarged detail view in the area of the integral bond of the baked goods core part and cover layer,

Fig. 3 is a cross-sectional view similar to FIG. 1, the multilayer

Animal feed additionally has a color and / or gloss layer above a middle cover layer,

4 shows a basic illustration of the process sequence in the production of the feed,

Fig. 5 shows a device for forming a pasta, from which a

Core part intended baked goods is generated,

6 shows a coating device with a rotary vessel receiving the baked core part, and

FIG. 7 shows a coating device similar to FIG. 6, the rotary boiler being provided for receiving core parts already provided with the cover layer in order to form a gloss layer. 1 shows a sectional basic representation of a portion body 1 intended as feed for dogs in particular, which consists of a core part 2 and a cover layer 3 in an embodiment which is generally known for feed. Portion bodies as two-layer extruded bodies, not shown, are known, from which animal feeds usually having different compositions are produced, this being provided as a granular structure, in particular in feeding bowls for feeding.

In the feed according to the invention, the individually manageable portion body 1 is provided with a core part 2 designed as baked goods 4, around which the at least single-layer cover layer 3 is formed on all sides with a substantially closed circumferential contour. Thus, a portion body 1 is provided, which has a spherical or ball, egg or bean-shaped contour, the dimensions (diameter A, Fig. 3) are optimally designed so that the portion body 1 can be handled individually and an animal-friendly access a reward campaign is guaranteed.

The partially enlarged sectional view II according to FIG. 2 shows the intimate bond of the baked goods core part 4 with the cover layer 3, this being connected in some areas to the core part 2 in such a way that a cohesive unit through parts B which are diffused into the baked goods 4 and which, in particular, consist of liquid Bold shaped top layer is formed. Depending on the consistency of the cover layer 3, it can harden in such a way that its outside 5 already ensures the stability of the portion body 1 even when subjected to pressure or heat. In an expedient embodiment, the cover layer 3 is constructed in multiple layers, the embodiment of the portion body 1 'shown in FIG. 3 above the cover layer 3 having a cover 7 provided as a gloss or color cover, under which a binder 6, 6', not shown in more detail, is also provided can be.

1 that the core part 2 and the cover layer 3 with different volume fractions can form the portion body 1. The core part 2 can cover 10 to 90% of the total volume, so that the proportion of the top layer 3 can largely vary between 90 and 10% as desired. The layer provided as a gloss cover 7 with a thickness C in the embodiment of the portion body 1 'in FIG. 3 is usually provided with a volume fraction of less than 10%.

In addition, it is conceivable that the core part 2 can also be formed from a multi-layer baked goods having a diameter B 'or the cover layer 3 or 7 also has more than the two layers shown. In addition, the adhesive 6, 6 'can be provided between each of the individual or more layers.

For the intended use of the portion bodies 1, 1 ', the baked goods part 4 can be formed from a mixture containing a few flavoring substances, while in particular in the top or gloss layer 3, 7 animal-friendly flavoring and flavoring substances are supplied. It is conceivable to insert 3 flavor-intensive and low-calorie protein substances, meat components or the like into the top layer 3. The portion body 1, 1 'have a consistency suitable for transport, so that they can be used as a reward article by a guide at any time. The individual portion bodies 1, 1 'have a structure rolled around the solid core 2, which is processed without an additional pressing process in the manufacture to a bite and digestive consistency, the air-dried top layer of which optimally releases the flavors and aromas.

4 shows the basic procedure for the production of the feed in the form of the portion bodies 1, 1 ', wherein in a first process step G the core part 2, which is designed as a baked goods 4, is formed from a pasta in a molding device and then exposed to the baking process , 5, a substantially spherical contour of the core part 2 is achieved, so that it can be rolled in the next method step H with little effort in a covering compound 3 forming the covering layer.

In particular, a fat substrate containing flavorings and flavorings is provided as the covering material for the covering layer 3, which is heated for coating. The core parts 2 are rolled at H in this liquid covering compound and the part located as a covering layer on the core part 2 is hardened for permanent adhesion by simultaneous cooling. The diameter of the respective cover layer or the diameter A ¹ (FIG. 1) of the portion body can be determined by a corresponding duration of the rolling phase at H.

The portion bodies 1, 1 'are temporarily stored in a process step K after the application of the respective cover layer 3, so that this layer can harden. This phase can last up to 24 hours. The portion body 1 can then be provided with additional cover layer (s) in method step L, the gloss layer 7 being provided for covering, for example, and the portion body 1 'being produced.

A machine system is provided for carrying out the above-described manufacturing method, which consists of several individual components, which are described in more detail below.

5 shows a pressing device, designated overall by 10, to which a baking device, not shown, is connected by means of two conveyor belts 11, 11 '. This allows a molded body F pressed from a pasta T to be brought into the final shape referred to as core part 2 after baking (basic illustration according to FIG. 5a).

In the pressing device 10, the pasta T is pressed into the respective mold troughs 21 of a molding roller 22 by means of a pressing roller P 'exerting a molding force P and then the molded part F is taken onto the conveyor belt 11 by means of a rubber roller 23 and continuously fed to the oven by means of the conveyor belt 11' ( not shown). It drives the pasta T up, so that the core part 2 with an almost circular cross section arises from the shaped part F (FIG. 5a).

For the further processing of the core material 2, a plurality of coating devices 13 (FIG. 6) or 14 (FIG. 7) that can be used one after the other in a row arrangement can be provided. These coating devices 13, 14 each have a rotary boiler 15, 15 'into which the respective intermediate product in the form of the baked goods 4 or in the form of the portion body 1 which has already been coated, and these parts can be individually coated by rotating the rotary boiler 15, 15 'by means of a corresponding drive kinematics 24.

In Fig. 6, 16 is the fat substance located in the rotary boiler 15, in which the core parts 2 (shown larger) can be moved. In order to achieve their optimum coating, the rotary boiler 15 has an axis of rotation D oriented at an acute angle to the horizontal plane E, and the central longitudinal axis M of the rotary boiler 15 is aligned essentially perpendicular to the axis of rotation D. This ensures that the substances 16 located in the interior of the rotary boiler 15 are collected in a boiler bottom region 17 having an arcuate cross section. Upon initiation of the rotary movement according to the direction of rotation arrow D ', the mixture of liquid fatty substance 16 and the baked goods core parts 2 is moved such that the rolling core parts 2' roll from the area of the kettle bottom 17 to a cylindrical wall area 18 and through one with the inclination of the wall area cause the return movement according to arrow R to repeatedly dip into the fatty substance 16, so that a uniform distribution and adhesion of the fatty substance 16 on the core parts 2 'is achieved.

At the same time, cooling air (arrow 20) is introduced into the interior of the rotary boiler 15 during this turning process via a conveying line 19 such that the fat covering layer 16 adhering to the core parts 2 is cooled and this covering layer 3 is thus increased in thickness in accordance with the duration of the rolling (A ¹ , Fig. 1). By setting the corresponding process parameters, portion bodies 1, 1 'of largely any outside diameter can be produced. In FIG. 7, the second coating unit 14, in accordance with the construction described above according to FIG. 6, is provided with a rotary boiler 15 ', in which in particular only the thinner gloss top layer 7 is produced. The likewise arc-shaped boiler bottom 17 'here has a wall 25 which is essentially spherical, so that the portion bodies 1' cover a smaller roll path R 'on the wall of the rotary boiler 15' and the cover layer 7 is therefore only exposed to the cooling air 20 for a relatively short time ,

For the operation of the process, it has been found to be expedient that in the coating device 13 shown in FIG. 6 to form the first cover layer 3, a fat solution 16 provided with potato starch, chicken and similar tensile substances with a temperature of 40 ° C. to 60 ° C., in particular 52 ° C, and the core parts 2 are introduced into this mixture through a container opening 26 (arrow N). The cold air 20 supplied during the rotation D ′ is supplied at a temperature of 5 ° C. to 20 ° C., preferably approximately 13 ° C., in accordance with the intended hardening process. Through the rolling process R, the portion bodies 1 along the roller plane 18 are also shaped such that when they move back into the bottom 16 of the bowl, they undergo a circular grinding by contact with one another, and the optically appealing spherical shape of the reward articles is thus preformed.

In order to calm the fatty substance 16 in the area of the top layer 3, the preformed portion bodies 1 'are stored and cooled for about 24 hours after removal from the rotary kettle 14. The portion bodies 1 'can then be introduced into the coating device 14 shown in FIG. 7 to form the gloss layer 7 (arrow N'). The substance 27 provided for the glossy outer layer is filled in the boiler 15 'as a powder-water mixture with a temperature of 60 ° C to 90 ° C, preferably around 75 ° C. The portion bodies 1 ′ moved in this mixture 27 are cooled by the cooling air supply 20, in particular dry air with a moisture content of only 30% to 40% being supplied and this air a temperature of 10 ° C. to 30 ° C., preferably 18 ° C. , having.

With the procedure described above and the devices shown, a defined single roll coating of the core parts 2 preformed as baked goods 4 is achieved, which in their overall structural structure have a largely porous core with a relatively soft, aromatic covering compound for the biting conditions of animals and in this respect an optimal reward article for dogs and other pets. This product is particularly harmless as a game element and can be used with a high training effect.
