Definitions
- the present invention relates to a roller mill for the production of food and animal feed with improved product collection.
- roller mills and their application are well known.
- An example of a prior art roller mill is in 1 shown, with only the most important components being identified in more detail.
- the roller mill 1' comprises an inlet 2' (for example a funnel) through which the material to be ground is fed to pairs of rollers 3' and 4'. The ground material then leaves the roller mill 1' through trimelles 5', into which it falls due to gravity.
- the trimels 5' which can be outlet funnels, for example, are guided through a floor 6' on which the roller mill 1 is arranged. Below the floor 6', the trimelles 5' open into a transport device (not shown), with which the material is conveyed further mechanically or pneumatically.
- Such a roller mill has some disadvantages. Since the trimelle 5' protrude through the floor 6' on which the roller frame 1' is located, an additional building floor must be provided below the floor 6', in which the removal device described above can be arranged.
- Roller mills are also known in which the product is conveyed away via direct suction.
- two collecting trimmels for the product are arranged on each roller mill side within the roller mill.
- a vacuum-pneumatic transport is then arranged for each collecting trimelle, ie four riser pipes are to be provided.
- larger roller mills e.g. a length of 1500 mm
- the present object is achieved by the roller mill according to the invention for the production of foodstuffs and animal feed.
- the present invention relates to a roller mill for the production of food and animal feed, comprising a product inlet, a grinding chamber with grinding rollers, into which bulk material to be ground can pass from the product inlet, and a product outlet unit arranged below the grinding chamber, into which product from the grinding chamber can pass.
- the product outlet unit comprises a Trimelle, which has a conveyor screw in its lower area facing away from the grinding chamber, the conveyor screw having two sections conveying in opposite directions in order to convey product from the lower area of the Trimelle to an outlet opening in the bottom area of the Trimelle.
- the present invention is characterized by a special product outlet unit.
- This product outlet unit includes a Trimelle. Trimelles and their use in roller mills are well known.
- a trimelle is a prism-shaped unit with an essentially triangular cross-section, the base area being oriented towards the grinding chamber and the end facing away from the base area being rounded off.
- the roller mill according to the invention for the production of foodstuffs and animal feed has a single trimelle, which extends over the entire width of the roller mill.
- the base of this Trimelle is completely open with respect to the grinding chamber of the roller mill, so that ground product can get from the grinding chamber into the Trimelle over the entire width of the Trimelle.
- corresponding trimelles can be arranged next to one another and together extend over the entire width of the roll mill.
- the Trimelle In its lower area facing away from the grinding chamber, the Trimelle has a screw conveyor, i.e. at the end facing away from the base.
- the end of the trimelle facing away from the base is rounded in order to be able to optimally accommodate the screw conveyor.
- the auger runs the full length of the lower section of the Trimelle. It is rotatably mounted on the two lateral ends of the Trimelle. A motor for moving the auger is operatively connected to the auger.
- the motor is preferably arranged at a lateral end of the trimelle, preferably fastened in a detachable manner.
- any motor commonly used for the movement of screw conveyors can be used. It is preferably a geared motor, particularly preferably an electric motor.
- the screw conveyor arranged in the Trimelle has two sections that convey in opposite directions.
- screw elements are arranged on one section of the screw conveyor which effect product conveyance from left to right, while screw elements which effect product conveyance from right to left are arranged in another section of the conveyor screw.
- the provision of two counter-feeding sections of the auger serves to feed product from the bottom of the Trimelle to an outlet opening in the bottom of the Trimelle.
- product is conveyed to the outlet opening from areas of the Trimelle located on both sides of the outlet opening.
- the screw elements are arranged at least in the area of the Trimelle which is open to the grinding chamber.
- the base of this trimelle is completely open to the grinding chamber of the roller mill, so that ground product from the grinding chamber can enter the trimelle over the entire width of the trimelle.
- screw elements are arranged over the entire width of the trimelle, except for the area in which the outlet opening is located.
- the sections of the screw conveyor conveying in opposite directions are connected to one another via an uninterrupted shaft, i.e. that only a single screw conveyor is provided.
- a single conveyor screw is subject to significantly less vibration.
- the outlet opening is most preferably located in the middle of the bottom surface of the trimelle, i.e. it is equidistant from both lateral ends of the trimelle.
- a component can be provided in the area of the outlet opening, which is intended to prevent product accumulation in this area.
- this can be a pen.
- the outlet opening opens into a pipeline, ie the outlet opening is arranged with a below the outlet opening pipe connected.
- the product is conveyed away from the roller mill through this pipeline.
- the outlet opening is preferably connected to the pipeline in such a way that the product gets from the outlet opening into the pipeline with the gentlest possible deflections. This reduces the risk of the outlet opening becoming clogged or blocked.
- the outlet opening is preferably designed in the form of a so-called feed shoe, in which an opening in the bottom area of the trimelle is connected to an opening in the top area of the pipeline via vertical or slightly inclined or curved side walls. In this embodiment, a transfer of product from the trimelle into the pipeline in a substantially vertical direction is ensured.
- the pipeline is arranged at an angle of approximately 90° to the trimelle, i.e. in the area of the outlet opening there is an imaginary line along the longest dimension (i.e. the width) of the trimelle and an imaginary central axis through the pipeline that they enclose an angle in the range of 60 ° to 120 °, particularly preferably 90 °.
- the pipeline for transporting the product away from the roller mill is constructed analogously to conventional pipelines for transporting product away from a roller mill.
- the product is preferably removed pneumatically, particularly preferably pneumatically by suction.
- the pipe is preferably connected to an air suction unit.
- air suction unit Such units are known and need not be explained in more detail here.
- the pipeline is arranged in a section below the trimelle and has an upward bend beyond the trimelle in order to be guided upwards past the trimelle at the side.
- the pipeline thus has a vertically upwardly arranged section which is connected via a bent element to the section of pipeline arranged under the trimelle.
- the pipeline is arranged on the trimelle in a removable manner, for example with one or more screw connections.
- the pipeline can also have additional attachment means for attachment to the roller mill itself, for example one or more additional screw connections.
- the product can be transported away without providing additional structural height within the machine.
- the roller mill can be placed directly on the floor. It is not necessary to provide an additional building floor as required in the prior art.
- the number of required trimelles can be reduced to one trimelle per side (and correspondingly one pneumatic pipe per side).
- the present invention thus provides significant technical advantages.
- the product outlet unit according to the invention can be used with any conventional roller mill.
- the use for roller mills for the production of food and animal feed is preferred.
- the present invention thus relates to a product outlet unit comprising a Trimelle, which has a conveyor screw in its lower area facing away from its base area, the conveyor screw having two sections conveying in opposite directions, in order to feed product from the lower area of the Trimelle to an outlet opening in the bottom area of the Trimelle carry.
- the product outlet unit according to the invention is constructed as described above.
- the roller mill can have one or two of the product outlet units according to the invention.
- the roller mill according to the invention for the production of food and animal feed is preferably used for the production of flour from grain and from the processing of grain milling products and grain end products from milling (in particular milling soft wheat, durum, rye, corn and/or barley) or special milling (in particular hulling and/or or milling soya, buckwheat, barley, spelt, millet/sorghum, pseudocereals and/or legumes), this being in particular bread wheat, durum wheat, corn or buckwheat.
- Bread wheat is also known as Triticum aevestivum and durum wheat as Triticum durum.
- rice is also understood to be grain.
- the roller mill according to the invention is also suitable for producing feed for livestock and domestic animals, fish and crustaceans.
- the roller mill is characterized by at least one grinder.
- Such roller mills are, for example, from EP-0 944 433 A1 , EP-0 991 473 A1 , WO 2019/224 399 A1 and the WO 2019/229 014 A1 known, to whose corresponding content reference is made.
- the ground product is then transferred to the Trimelle of the roller mill according to the invention. This occurs through the influence of gravity, in that the product from the milling chamber falls through the open base of the Trimelle into the Trimelle.
- conveyance of the ground product is performed by the auger located in the Trimelle to an outlet opening as described above.
- the oppositely conveying sections of the screw conveyor cause the product to be conveyed from both areas to the side of the outlet opening in the bottom of the Trimelle to the outlet opening.
- the product conveyed into the outlet opening is transferred into the pipeline. As described above, this is preferably done with deflections that are as gentle as possible, ie the direction of movement of the product changes as little as possible during the transfer.
- the product is simply brought together from the left and right into the center of the Trimelle. From there it leaves the Trimelle downwards (horizontal movement is converted into vertical movement, or via the inclined geometry of a feed shoe) into the suction pneumatics pipeline. This is preferably accomplished with the aid of the dispensing shoe described above.
- the product is conveyed away from the roller mill as described above. This is preferably done pneumatically, particularly preferably pneumatically.
- FIG. 12 shows a schematic view of a roller mill for the production of foodstuffs and animal feed from the prior art Technology, with only the most important components being identified in more detail.
- the roller mill 1' comprises an inlet 2' (for example a funnel) through which the material to be ground is fed to pairs of rollers 3' and 4'. The ground material then leaves the roller mill 1' through trimelles 5', into which it falls due to gravity.
- the trimels 5' which can be outlet funnels, for example, are guided through a floor 6' on which the roller mill 1 is arranged. Below the floor 6', the trimelles 5' open into a transport device (not shown), with which the material is conveyed further mechanically or pneumatically.
- the roller mill 1 comprises an inlet 2 (for example a hopper) through which the material to be ground is fed to pairs of rollers 3 and 4 .
- the ground material then leaves the roller mill 1 through trimelles 5, into which it falls due to gravity.
- the trimelles 5 have in their center an outlet opening 7 in the form of a feed shoe, through which product enters the pipeline 8 .
- the components 5, 7 and 8 together form a product outlet unit P.
- the pipelines 8 of the two in 2 trimelles shown, are arranged such that the vertical portion 8a of one of the ducts 8 is juxtaposed with the vertical portion 8a of the other duct 8.
- the roller mill 1 stands on a floor 6 with the help of legs 9.
- FIG. 3 a schematic view of the product outlet unit P according to the invention is shown.
- an auger 10 arranged, which has a conveying from left to right section 10a and a conveying from right to left section 10b. Between these sections 10a and 10b, in the area of the outlet opening 7, there is a section 10c without screw elements.
- the screw conveyor 10 is rotatably mounted on the lateral ends of the trimelle 5.
- the auger 10 is connected to a motor 11 by which it is driven.
- the pipeline 8 runs horizontally below the trimelle. Behind the trimelle 5, the pipeline 8 has a bend and merges into a vertical area 8a.
- In 4 is a longitudinal section through the product outlet unit P according to 3 shown, with like reference numerals denoting like components.
- the shape of the feed shoe 7 can be seen, which connects the opening in the bottom of the trimelle 5 with the opening in the top of the pipeline 8 in such a way that the product is transferred from the trimelle 5 into the pipeline 8 with the gentlest possible deflections.
