Description

  • The invention relates to the field of milling, in particular the Mahlvorbehandlung of cereals.
  • The grain has, simplified, a triple shell structure. The outer shell layer comprises the epidermis, longitudinal and transverse cells as well as tubular cells. This outer shell layer can make up to 5.5% by weight of the whole grain. The next inner layer is a double layer of a so-called dye layer and a colorless layer; for this double layer, a proportion of about 2.5% by weight of the whole grain is assumed. The next inner layer is called the aleurone layer and comprises about 7% by weight of the whole grain. Inside the grain is to find the germ (about 2.5 wt .-% of the total grain), as well as the actual meal body, which accounts for the rest to 100 Gesamtgew .-%.
  • It is known to pretreat the grain in such a way that it peels, grinds and / or polishes in such a way that as few peel constituents as possible enter the actual grinding process.
  • DE 1 164 210 proposes a multi-stage process in which already in a first step, the shell components are replaced in an amount of 2.8 to 3.6 wt .-% of the cereal grain. In a second step, another 0.4 to 2.1 wt .-% of the cereal grain are replaced again. In total, between 3.2 and 5.7% by weight of the cereal grain are replaced cumulatively in this process.
  • It is also known that environmental poisons and / or impurities may be present in an outer layer of the crop. That this by removing part of the outermost shell The cereal can be removed, for example, in EP 801 984 B1 described.
  • The document GB 2 268 386 A discloses a method for treating cereal grains prior to milling, in which the grains are wetted, a first fraction of the bran wrap is removed, the grains are cleaned and then moistened again, and then the remaining portion of the bran wrap is removed. However, the weight fraction of the first fraction which is removed after the first moistening is not disclosed.
  • In the document EP 0 810 031 A2 discloses a pretreatment process for cereal grains with a total of three polishing steps. Again, however, the weight fraction of the outer layer removed in the first step is not mentioned.
  • The invention has for its object to provide a method by which both contaminated outermost layers of the grain can be reliably removed as well as the grain as much as possible can be added to a value-added use. The method should also be as simple, efficient and inexpensive feasible.
  • This object is solved by the subject matters of the independent claims.
  • The process for the preparation of cereals according to the invention comprises the following steps:
  1. a) Provide cereals.
  2. b) Optional: meshing and conditioning of the crop, especially during a period of ≤ 1 hour, preferably during ≤ 10 minutes, more preferably for about 5 seconds to 5 minutes, more preferably for about 5 seconds to 30 seconds, most preferably for about 8 seconds to 15 seconds.
    It has been shown that this step can be dispensed with depending on the degree of contamination and type of contamination. In general, with prior meshing and conditioning of the cereal, more outer shell components may be removed in subsequent step c), if desired or necessary (due to the degree of contamination and / or the nature of the contamination).
  3. c) Selective removal of a first fraction of shell constituents of the cereal according to step a) or of the crop obtained from step b), this first fraction essentially comprising the outer shell constituents of the grain crop.
  4. d) meshing and conditioning of the cereal obtained from step c), especially during a period of 0.5 to 30 minutes, preferably for 0.5 to 15 minutes, more preferably for about 1 to 5 minutes.
  5. e) selectively removing a second fraction of shell constituents of the crop obtained from step d), said second fraction essentially containing dietary fibers of the sweetened grain.
  • According to the invention, 0.2 to 2% by weight of the cereal are removed in step c), preferably 0.2 to 1% by weight, particularly preferably 0.2 to 0.5% by weight. In step c), only the surface layer is removed to such an extent that contamination as environmental toxins and / or other impurities are removed. Surprisingly, it has been found that for this purpose the removal of only 0.2 to 0.5 wt .-% is completely sufficient to obtain largely contamination-free cereal grains. In step e), another layer is removed which is then substantially free of contaminants and which substantially contains dietary fiber of the crop. The thus obtained, contamination-free dietary fibers can be supplied as value components of a further use.
  • For the purposes of the present invention, dietary fibers are understood as meaning the total dietary fibers, determined in accordance with AOAC 985.29.
    The provision of grain in step a) can take place with so-called "storage moisture" or "ground moisture".
  • The provision of "grinding moisture" is carried out with a moisture content of ≥ 14 wt .-%, preferably 14 to 20 wt .-%, more preferably 15 to 20 wt.%, Particularly preferably 15 to 17 wt .-%, said moisture as possible is largely homogeneously distributed in the grain, as it is optimal for the milling process.
  • The provision with "storage moisture" is preferably carried out with a moisture content of <14 wt .-%, preferably 8 to 13.99 wt .-%, particularly preferably 10 to <13.99 wt .-%.
  • It has been shown that the meshing of the grain in steps b) and d) can be done with very little water. Typically, for example, from 0.1 to 3.5% by weight, preferably from 0.2 to 2.5% by weight, of water is added (based on the resulting total weight) if grain having the above-mentioned "ground moisture" is provided ,
  • If grain with the o.g. "Storage moisture" is provided, typically between 0.1 to 4 wt.%, Preferably 0.2 to 2.5 wt.%, Of water is added (based on the resulting total weight).
  • The conditioning in steps b) and d) can take place directly during the meshing of the grain, for example in a vortexer. However, the conditioning can also take place only partially directly during meshing (for example, in a screw conveyor, is fed into the water), in which case then a separate conditioning of the strained cereal takes place (eg. In a screw conveyor, in which no additional water is fed more ).
  • The meshing and conditioning of the grain in steps b) and d) surprisingly leads to sufficient moisture contents in the outer layers of the grain, which already sufficiently facilitate the subsequent distances of shell layers in steps c) and e).
  • Typically, in step b), during a period of ≤ 1 hour, preferably for ≤ 10 minutes, more preferably for about 5 seconds to 5 minutes, more preferably about 8 seconds to 30 seconds. This meshing is preferably done in a vortexer.
  • Typically, in step d), it is wetted and conditioned for about 0.5 to 30 minutes, preferably 0.5 to 15 minutes, more preferably 1 to 5 minutes. This network is preferably carried out in a network and residence screw conveyor. While in step c) only just as much surface layer of the grain is removed that a substantially contamination-free residual grain is obtained in step e) a fraction with the highest possible dietary fiber content is obtained, the flour body should not be damaged as possible. The proportion of the second fraction obtained in step e) in% by weight of the total grain may vary depending on the type of cereal and the contaminated layer removed in step c). However, proper control of the process can be readily determined by routine experimentation; For this purpose, the content of total food fibers of the second fraction and the content of starch (as an indication of damage to the endosperm) can be used (individually or in combination).
  • In preferred embodiments, therefore, the second fraction removed in step e) has a total dietary fiber content of ≥60% by weight, preferably ≥70% by weight, more preferably ≥80% by weight.
  • In further preferred embodiments, the second fraction removed in step e) has a starch content of ≦ 20% by weight, preferably ≦ 15% by weight, particularly preferably ≦ 10% by weight.
  • The content of starch is determined in the context of the invention according to the Swiss Food Book SLMB (2002), chapter 3.6.1.
  • In particularly preferred embodiments of the invention, step e) is carried out in several substeps e 1 ) to e n ). The fractions obtained in such sub-steps may in particular contain varying amounts of grain (in% by weight of the total weight of the cereal used). hereby a particularly fine approach to a maximally exposed flour body can be achieved; In particular, the isolated fraction can be chosen the smaller, the more dietary fibers have already been removed.
  • Particularly advantageously, the fractions or partial amounts thereof obtained in substeps e 1 ) to e n ) can be mixed with one another such that the mixture has a total dietary fiber content of ≥ 60% by weight, preferably ≥ 70% by weight, more preferably ≥ 80% by weight. The first partial fractions typically have a total dietary fiber content of> 80% by weight, in particular> 85% by weight. Later partial fractions can - despite lower content of total dietary fiber - also isolated and mixed with the former sub-fractions, as long as this does not fall below a desired total dietary fiber content (or a maximum tolerated starch content, see below).
  • Further advantageously, the fractions or partial amounts thereof obtained in substeps e 1 ) to e n ) can be mixed with one another such that the mixture has a starch content of 20% by weight, preferably ≦ 15% by weight, more preferably ≦ 10% by weight. The first partial fractions typically have a starch content of <6% by weight, in particular of <5% by weight. Later sub-fractions can - despite higher content of starch - also still isolated and mixed with the former sub-fractions, provided that this maximum tolerated starch content is not exceeded (or a desired content of total food fibers is not exceeded).
  • Between the individual sub-steps e 1 ) to e n ) can advantageously be carried out a new meshing and conditioning of the grain.
  • In further preferred embodiments, the meshing and conditioning takes place in steps b) and d) and, if appropriate, between substeps e 1 ) to e n ) with a swirling network or with a network and residence-screw conveyor. A vortex setter has surprisingly been found to be particularly suitable for use in step b), whereas the net and indwelling screw conveyor has proved to be particularly effective in step d) and optionally between sub-steps e 1 ) to e n ); In particular, the sequential use of a net screw conveyor (with added water) and a subsequent residence screw conveyor (without addition of water) has proven to be particularly advantageous.
  • The removal of the constituents of the first and / or second fraction in steps c) and e) from the cereal grain takes place particularly advantageously essentially by grain / grain friction. Such friction is particularly gentle, which manifests itself in a small grain breakage. Alternative methods based essentially on grain / metal or grain / stone friction are less gentle and therefore in many cases unsuitable for achieving the desired selectivity of shell component removal desired in steps c) and e).
  • Another disclosed but not claimed aspect relates to a plant for carrying out the process described above. Such a plant comprises in the product flow direction:
    1. a) Optional: at least one standby cell for preconditioning the grain to a defined moisture content;
    2. b) optionally: at least one net aggregate for netting and conditioning the grain, preferably a vortexer;
    3. c) at least one device for peeling surface treatment of the grain;
    4. d) at least one network unit for re-meshing and conditioning of the grain, preferably a net and indwelling screw conveyor;
    5. e) at least one device for peeling surface treatment of the grain.
  • It is understood that with suitable process control (for example, with intermediate storage of intermediates) in steps b) and d) if necessary, the same mesh unit can be used; likewise, in steps c) and e), the same apparatus can be used for peeling surface processing. However, a continuous operation of the plant with separate devices for peeling surface treatment in steps c) and e) is preferred.
  • In the apparatus (s) for peeling processing of the grain, peeling is particularly advantageously achievable essentially by grain / grain friction, as already explained above in connection with the method according to the invention.
  • The apparatus for peeling surface processing in the above-described systems has the following components particularly advantageously:
    • ∘ a rotatably mounted rotor;
    • ∘ a stator, which is provided in particular with editing tools;
    • ∘ at least one screen basket, which is formed in particular from one or a plurality of screen plates and is preferably arranged on the stator, wherein the at least one screen basket surrounds the rotor such that a processing zone is formed;
    wherein the rotor comprises a hollow shaft, through which air can be fed into the processing zone, and wherein the rotor in the region of the processing zone comprises a roller which is provided in particular with processing tools.
  • As processing tools can be provided on the stator planar segments; But these segments can also be equipped with baffles, cams o. The like.
  • As editing tools on the rotor projecting strips, knobs o. The like. Be provided.
  • The baskets can be adapted to the specific application (in particular to the respective type of grain) with expert routine tests, in particular in their hole dimensions.
  • Another disclosed but not claimed aspect relates to the use of dietary fibers obtained by a process as described above, in particular with a plant as described above, as an additive in foods, in particular baked goods, preferably breads; cereals; Snacks, in particular bars; Beverages; Dairy products, in particular yoghurt; Food supplements; Diet food. According to the invention, substantially contamination-free dietary fibers can be obtained in a particularly simple and high yield, which can thus be supplied to a further use. The resulting, Treated (freed from an outer layer of the shell components) Korngut can also be further processed.

  • In the flowchart in Fig. 1 In a variant for carrying out the method, grain from a stand-off cell (not shown) is fed to the process with a defined moisture content. The grain first passes through a magnet 1 for sorting out metallic parts. Subsequently, the grain is fed to a Wirbeletzer 2, which has a water supply 3 for meshing the grain. The vortexer 2 is added in the description Fig. 6 explained in more detail. Subsequently, the corn is fed to a first device for peeling surface treatment of the grain, namely a so-called Light Peeler 4; this is related to Fig. 2 and Fig. 3 explained in more detail. However, instead of a light peeler, a peeler 12 can also be used; this is related to Fig. 4 and 5 explained in more detail. The fiber fraction leaving the Light Peeler 4 (or Peeler 12) can be recycled (not shown). The grain fraction is passed through an aspiration channel 5. Here the loose parts are sucked off, which were not removed by the screen jacket of the Light Peelers. The grain is then fed to a depot 6, in which it can be stored temporarily to compensate for different capacities of the individual process stages. By means of a balance 7 can be ensured that the subsequent process stages defined amounts of grain are supplied, which is essential in particular for the subsequent network. In a net screw conveyor 8, the grain is wetted and promoted at the same time; the net screw conveyor 8 is fed via a water supply 9 with water. The strained grain is then conditioned in an indwelling screw conveyor 10. The construction of auger conveyor 8 and indwelling screw conveyor 10 is identical except for the water supply and is associated with Fig. 7 explained in more detail. The strained grain is in turn passed to a magnet 11 to sort out any metallic contaminants. Subsequently, the grain is fed to a second apparatus for peeling surface treatment of the grain, here a peeler 12; this is related to Fig. 4 and Fig. 5 explained in more detail. However, in this process step, a light peeler 4 can alternatively be used if a gentler treatment with less removal of shell material is desired. The fiber fraction leaving the peeler 12 can be sent for further use (not shown). The grain passes another Aspirationskanal 13 and another magnet 14 and is then fed to the grinding process.
  • In Fig. 2 and Fig. 3 the Light Peeler 4 is shown in more detail. The grain is supplied to the light peeler 4 via a product inlet 15 and reaches a feed screw 20. The light peeler 4 has a stator 19 and a rotor 25. Between rotor 25 and stator 19 and screen plates 27 (FIG. Fig. 3 ) is formed a processing zone 18 for the grain. The distance between rotor 25 and stator 19 can be reduced above and below by underlaying the segments 41, in order to achieve a more intensive treatment of the process material. The distance of the screen plates 27 to the rotor 25 can also be adjusted; a greater distance is accompanied by a gentler treatment of the process material. The rotor 25 has a hollow shaft 26 which is driven by a motor 23. The hollow shaft has air openings 24, via which air can be supplied in the processing zone 18. By regulating the storage devices 21 and 22, the treatment intensity in the processing zone 18 can be regulated by adjusting the back pressure of the grain in the Light Peeler 4. Via the outlet 16, the fiber fraction leaves the light peeler 4; the treated grain leaves the Light Peeler 4 via the outlet 17.
  • In Fig. 4 and Fig. 5 the Peeler 12 is shown in more detail. Parts having substantially the same function are designated by the same reference numerals as in the light peeler 4. The cereal is supplied to the peeler 12 via a product inlet 15 and reaches a feed screw 20. The peeler 12 has a stator 19 and a rotor 25. Between rotor 25 and stator 19 and screen plates 27 (FIG. Fig. 5 ) is formed a processing zone 18 for the grain. The distance between rotor 25 and stator 19 can be reduced at the top and bottom by underlaying the segments 41, thus to achieve a more intensive treatment of the process material. The distance of the screen plates 27 to the rotor 25 can also be adjusted; a greater distance is accompanied by a gentler treatment of the process material. The rotor 25 has a hollow shaft 26 which is driven by a motor 23. The hollow shaft has air openings 24, via which air can be supplied by means of a fan 28 in the processing zone 18, whereby the separation of the shell fraction can be facilitated and completed. The treatment zone 18, which is narrower in the case of the peeler 12 in comparison to the light peeler 4, also intensifies the treatment of the grain (cf. Fig. 3 ). By regulating the storage devices 21 and 22, the treatment intensity in the processing zone 18 can be regulated by adjusting the back pressure of the crop in the peeler 12. Via the outlet 16, the fiber fraction leaves the peeler 12; the treated grain leaves the peeler 12 via the outlet 17.
  • In Fig. 6 the vertebrae setter 2 is shown in detail. The cereal is fed to the vortexer 2 via the product inlet 34 and passed through the vortexer in a helical direction (indicated by the arrow line in the interior of the vortexer 2). About a not shown in detail water inlet 2 water is metered supplied to the interior of the vortex network. In the interior of the Wirbeletzers 2, an upper shaft 30 and a lower shaft 31 are arranged; Paddles 32 and 33 are provided on these rotating shafts in such a geometry and arrangement as to achieve the above described helical conveying movement. The shafts 30 and 31 are driven by a common motor 29. The strained corn leaves the vortex network via the product outlet 35.
  • In Fig. 7 For example, an indwelling screw conveyor 10 is shown in detail. The grain is fed to the indwelling screw conveyor via a product inlet 36. In the interior of the dwell screw conveyor 10, a shaft 38 is arranged, on which paddle 40 provided in such a geometry and arrangement that a conveying movement is achieved. The grain exits the indwelling screw conveyor via the product outlet 37. The shaft 38 is driven by the motor 39. A net screw conveyor not shown in detail may be designed in an analogous manner, with only one water supply being provided preferably in the front part of the interior in the direction of product flow.
  • The following results were obtained by way of example with the method according to the invention:
    • The wheat used was Swiss quality wheat, with a moisture content of 12.6% by weight and an ash content of 1.83%, based on the dry matter. Before the experiment, the wheat was wetted to a moisture content of about 16% by weight. The subsequent standing time before the experiment was 18 h.
  • The netting was carried out with a Wirbeletzer 2. The surface treatments were carried out with a Peeler 12 (MHXM-W, Bühler AG).
  • The Peeler 12 was always operated with the following settings: Performance product receipt: 3 t / h Speed of the rotor: 335 rpm Screen size: 1.1mm x 12mm Distance rotor to segment 41: 13 mm Distance rotor to sieve: 8 mm
  • Prior to each surface treatment in Peeler 12, a net was placed in the vortexer 2 (hereinafter: Experiments 1 to 4), with a flow time through the vortexer 2 of approximately 0.3 minutes, and with the following amounts of water added to the network: Trial 1: 0.2% by weight Trial 2: 0.4% by weight Trial 3: 0.6% by weight Trial 4: 1.4% by weight
  • Subsequently, a shell fraction was separated after network in a net screw conveyor 8 with subsequent indwelling screw conveyor 10 (hereinafter: Experiment 5). 2% by weight of water was added to this netting, with a dwell and conditioning time in the net screw conveyor 8 and the dwell screw conveyor 10 prior to entry into the scrubber 12 for a total of 3 minutes.
  • The resulting fractions from experiments 1-5 were characterized as follows: Attempt # 1 2 3 4 5 Isolated fraction in% by weight of the total grain used 0.36 0.43 0.50 1.76 1.4 ash 1.90 1.81 1.86 2.11 3.37 Total dietary fiber in% by weight 88.0 86.5 85.1 86.4 61.2 Starch in% by weight 2.99 4.09 4.09 2.08 12.8
  • It can be seen from the above results that with the method according to the invention and with the use of a plant described above, shell components of the grain can be selectively isolated and successively separated, without the flour body being significantly damaged. At most, damage to the endosperm can only be assumed in fraction 5, since the starch content has risen to 12.8% by weight in each case. Nevertheless, this fraction can still be used, since it also contains 61.2 wt .-% - ie mainly - total food fibers.
  • With the fraction according to experiment 1, essentially all contaminations have already been separated off. A combination of the fractions according to experiments 2 to 4 (possibly also including the fraction according to experiment 5, see above) thus results in a high-purity fraction of total food fibers, which can be supplied for further utilization in food.
