Definitions

  • the invention relates to a method for revealing with diametrical turbulence friction shower-washed whole grain cereals on an optimal dividing line by localizing a predetermined amount of moisture on the morphologically determined dividing zone between the longitudinal and transverse cell layers with the greatest possible efficiency of reducing environmental pollutants, toxins and problem bacteria by optimizing the evenly complete surface removal Grain gap opening and cleaning with diametrical single-grain impact turbulence and exhaust air disposal of the husk and centrifugal force conveyance of the grains with the preparation for energy-saving grain comminution with a larger ground product surface for faster and higher water absorption, good swelling with larger dough and pastry volume for improved gelatinization and efficiency of the starch digestion through the kinetic wear of the endosperm cell groups for efficiency in leavening u nd pure grain, bread, pastry taste with good digestibility from hygiene and unencumbered microflora of high-tech refinement with diametric turbulence rubbing for nutritional enjoyment.
  • the invention also relates to a method for the intensive cleaning of grains, granules, legumes, nuts, seeds and other grains with diametrical impact turbulence friction, preferably by revealing shower-washed whole grain cereals for the quantitative completion of the technical process management for the substantial as well as material grain tissues and grain constituents due to the less intensive mechanical stress and injury of the grains due to the peeling effect and the achievement of the optimal dividing line by localizing the depth of penetration of the water to the morphologically predetermined separation zone between Longitudinal cell layer and transverse cell layer by lifting the surface tension and centering the water in a shower wash, which penetrates evenly quickly over the hygroscopic total grain surface, whereby the non-absorbed moisture is thrown off so that it does not enrich the abdominal furrow, capillaries and deep-lying shell tissue with swollen dirt and instead of it Transcontamination, the reduction of problem bacteria, environmental pollutants and toxins is achieved and the nutritionally hygienic priority is given to the efficiency of the grain contents.
  • the diametrical impact turbulence friction is carried out with a large speed difference of 20-50 m / sec and takes place between working profile discs with sustainable wear and tear and loosening of the genetic cell aggregates of the grain endosperm for the purpose of a larger product surface of the ground grains with improved water absorption, swelling, elasticity, volume increase and Efficiency in the microflora for the technological sourdough development of the grain ingredients and for a pure taste and digestible digestion for nutritional enjoyment, which is well perceptible on the grain, on the ground product and in the pastry with the sensory organ.
  • the grains prepared according to the invention for a uniform grain surface removal on the predetermined dividing line between the longitudinal cell tissue layer to be removed and the transverse cell tissue layer to be obtained on the grain are immediately and repeatedly bounced in the impact turbulence friction, and as a result the grain gap is emptied and further opened and emptied again.
  • the goal is Grain surface processing for the nutritional physiological health value achievable and more than just intensive processing of the grain surface with the known defects of round peeling, high water consumption and the uncontrolled attack in the hemp plant, or even soaking in lime-enriched water (DE-PS 295 27 08).
  • the seedling of the grain must also be preserved in the case of whole grain, but this is removed in the dry peeling machines.
  • An essential feature of the present invention is the hurling through profile elevations and / or depressions, for example surface elevations and / or depressions similar to diamond parallelogram pyramids, with angles of 20 degrees - 40 degrees: 30 degrees - 60 degrees length: width on or in Work documents, which are advantageously arranged offset, rotate coaxially with a large circumferential speed difference with the axis, and which are coaxially assigned to work surfaces of corresponding design at the same volume.
  • the rotational speed difference is 20 - 60 m / sec without allowing grain breakage by moving the grains on the way to work, starting at the discharge angle on an inclined plane in a semicircle up to 180 degrees and angular depth from 30 - 60 degrees, against the axially arranged, diametrically standing surface profiles and work documents, rebound and with the grains of others, in front, above, to the side and offset work surface profiles of 2,000 - 6,000 pcs / sq.m. in turbulence, rub against each other, rub and again offset from the coaxial circumferential profile elevations and / or depressions by the centrifugal force and accelerated to an increasing extent of the coaxial distance, are transported to the outer edge of the ring disks.
  • the profiles, which do not touch each other, are diametrically opposed to each other and are preferably designed in key form, contrary to the technical centrifugal force generated and increasing at a coaxial distance, for greater contact pressure on the underrun and accelerator, with greater dynamics in the impact turbulence friction acts.
  • the grains and sleeves leaving the machining process at the edge of the disk meet centrifugally against a cylinder which is at a distance from the aspiration ring shaft and whose working surfaces are equipped with positive and / or negative embossments.
  • the grains fall against the counter-flowing air in the aspiration shaft into the ring collecting funnel with an asymmetrical outlet, which is pierced around the shaft by a centripetal cylinder and through whose cylinder the aspiration air is sucked in.
  • the grains are fed centripetal axially onto the lower undercarriage for post-treatment and undergo a second impact turbulence friction process.
  • a variable adjustment in the axial dimension of the diametrically opposed working profiles is necessary in order to regulate the size of the grain and the genetic grain hardness and the optimal impact volume.
  • This is achieved in that a hollow shaft with a corresponding keyway is axially at a standstill and slidably supported during operation by the driven solid shaft with insert key and a cylinder with an external thread around the centripetal solid shaft supports the bearing of the solid shaft on the base plate and a second, larger cylinder with internal thread, axially adjustable, supports the mounting of the hollow shaft with the underrun body, so that manual and / or motor-regulating adjustment can be carried out, which, depending on the load, automatically adjusts to the flow rate measurement of the shower linen cone to an adjustable, extrapolates the changed setpoint and delivers it with electronic control, automatically, regulating.
  • the double cylinder bearing is mounted on a recessed base plate with three feet so that when the cylinder is turned horizontally, the bearing feet with the double cylinder can be axially disassembled and mounted through the base plate in order to quickly replace damaged bearings during continuous operation and in bulk goods processing.
  • the removed sleeves are suctioned off during the entire machining phase, both in the distance between the work pads and in the deflection at the impact brake deflection rings at a distance around the outer edge of the pane and when falling in the aspiration shaft with counter-flowing air from below, through the the outlet slope of the cylinder collecting funnel, coaxial around the double shaft and the cylinder bearing (s), which is drawn axially, deflected on the underflow working body, directed upwards into the aspiration ring shaft and discharged through the cover at three points, corresponding to the 3/3 division the extendable and adjustable rigid work surfaces, including aspiration ring shaft in 3/3 division.
  • an aspiration ring shaft with a narrowing ring width is assigned to the outside and combined into a ring at the top.
  • the diameter of the impact turbulence friction disks increases as a result of the additional aspiration shaft around the aspiration ring shaft, from top to bottom of the axially arranged treatment disks, and even with subsequent feeding onto the treatment body, only one aspiration ring shaft leads the wholegrain grains to the asymmetrical outlet of the Ring collecting funnel.
  • the efficiency of the impact turbulence friction is particularly high with special preparation, both for the completeness of the detachment, as well as compliance with the predetermined separation line of the sleeve detachment, if a targeted application of a certain amount of water can be ensured in a unit of time.
  • the amount of spun off could be reduced to a minimum.
  • a load cell scale in the suspension of the feed-regulating delivery cone determines the throughput and sends the corresponding values to an electronic computer outside the system, which compares the measured values with a target value and extrapolates whether the value is in the maximum range or whether the setting value has to be readjusted and itself executes the commands as to whether, for example, the depth of penetration of the cone tip into the feed cylinder is given by a signal to the feed motor and determines the expected change in the distance to plus or minus.
  • the command goes to a brake motor with pinion, which is set to the notched, centric, axially vertical round shaft and which lowers or increases the shaft carrying the cone, thus increasing or reducing the throughput.
  • the load cell scale is mounted centripetal horizontally on a tube cross in the funnel and records the throughput values from the cylinder in which the servomotor regulates the penetration depth of the shaft.
  • Pressure rollers on articulated arms hold the cone from the inside in vertical balance from the cylinder on the electronic load cell scale, which reports the determined data to the computer outside the unit, via a cable, through one of the empty pipes from the pipe cross and in the same way the commands to the Servomotor transmitted, which changes the flow with up and down.
  • the water metering is regulated according to the product code via an electronic regulating valve from outside, as is the diametrical spacing of the work surfaces via the product code and the speed of the Vario plug-on drive motor.
  • the process features of the present invention can be seen in that the granules are subjected to a shower wash in which only a little more water is provided than is necessary to coat or enclose the surface of the granules. In countercurrent to the water, an air stream is passed past the grains, thereby eliminating excess water.
  • the pretreated grains are subjected to impact turbulence by being guided in a room with fixed and rotating work pads, the work pads being formed with protrusions and / or depressions that accelerate the impacting grains diametrically turbulently.
  • Fig. 1 shows a covered cylinder 2 and a funnel 3, which hangs on the cylinder 2 by means of hanging bands 15 with an axial distance.
  • a funnel 5 is arranged concentrically on the cover, above the tip of another concentric cone 1.
  • the tip of the cone 1 is adjustable in the axial direction at a distance 8 by the height adjustment of the cone suspension 9.
  • the grain flow in the interior of the cylinder 2 is visible through a control window 16.
  • the cone 1 ends concentrically below in a larger funnel 7, which is suspended below the cylinder 2 and in the side of a tube 4 for the water supply to one
  • Spray head 11 arranged concentrically in the funnel 7 leads with six nozzles 17 which are horizontally offset by 60 degrees and aligned with the funnel 3.
  • the spray head 11 is also equipped with a concentrically arranged lower nozzle 18, so that the hollow veil of cones formed is sprayed completely from the inside.
  • the tube 4 is formed by two empty tubes lying diametrically on the wall of the funnel 7 to form a tube ring 78 which serves as a support 85 for a flow meter 86.
  • a cylinder 87 acts on the inner wall of the cone 1 via movable support roller arms 88 in order to regulate the immersion depth of a shaft 90 via a servomotor 89.
  • Each three footrests 45 (FIG. 2), each divided in length by a double flange 58, serve to hold a vertical shaft 21.
  • Working body 35 and sloping conical surfaces 33 are arranged on the shaft 21 or a hollow shaft 40 as an underrun with work coverings.
  • Impingement cylinders 38 and 28 are provided in order to brake and divert the grains and to guide them into the collecting funnel 43 against the inflowing aspiration air.
  • the collecting funnel is formed with an outlet 54.
  • the collecting funnel 43 is in the region of the shaft 21 and the hollow shaft 40 by a cylinder 50 in arranged there the run-off slope is broken.
  • a rider 73 directs the granules around the cylinder 50 through which the aspiration air is drawn in and is finally discharged to the outside via the air suction port 24.
  • the shaft 21 is supported on the machine cover 44 with an upper bearing 42.
  • Beam profiles 29 are intended to absorb dynamic vibrations and the load on the shaft 21.
  • a double cylinder bearing serves to redirect the forces to a base plate 51, which in turn is reinforced by supports 39.
  • a gear motor 20/57 for the shaft 21 is mounted under the base plate 51.
  • the grains pretreated in the funnel 3 (FIG. 1) - it is a type of shower wash in which the grain surface absorbs and swells up moisture - are fed to the work surface via an inlet 49 (FIG. 2), an inlet funnel 48 and a cylinder 32 of the working body 35 supplied.
  • the work surface of the working body 35 is flatter with a plurality of projections and / or depressions projecting in the axial direction, preferably in shape Pyramids, designed to "shoot" impacting grains with a pronounced axial movement component, so that their grain gap is opened and a cleaning effect is achieved.
  • the pyramid is to be understood as meaning all conceivable geometric configurations, the extent of which extends from a base area to a tip, that is to say also irregular configurations, which are also distributed unevenly on the work coverings.
  • This processing leads to the fact that the outer wood fiber casing of the grain, the epidermis with tufts, can be detached or detached up to a predetermined separation zone, which could not previously be achieved with known grain cleaning processes.
  • the special advantages of this treatment - the so-called shower wash with subsequent detachment of the outer shell by diametrical impact turbulence - leads to a relatively large surface of the ground product, lower energy consumption during grinding and an additional increase in grinding efficiency.
  • the ground product from grain pretreated in this way can absorb a larger amount of water and therefore causes a greater increase in volume in wholemeal pastries.
  • the above-described pretreatment can ensure that the environmental pollutants, poisons and problem bacteria, which are often deposited individually or in large quantities on the epidermis and beards, do not get into the dough and that targeted sourdough management is made possible, while at the same time the grain ingredients, which are significant are more open to digestibility and nutritional enjoyment.
  • the present invention it is possible not to feed the grains emerging from the funnel 3 directly to the inlet 49, but to provide an intermediate stage in which the surface water is removed from the grains.
  • This surface water usually contains a considerable amount of dissolved dirt, so that the end product, the grain to be ground, meets even higher hygienic requirements if this surface water is removed before the treatment by turbulence or dissolved dirt does not move transcontaminatingly into the grain furrow.
  • Screening devices in particular rotating screen cylinders with screen slots and the like, are suitable for this purpose. Such a device is described with reference to FIG.
  • a steel trough 65 with a collecting trough bottom is inclined horizontally and axially obliquely on shorter feet 73 and higher feet 70.
  • End-side cylinder connectors have an inlet pipe 62 on the low end side and an outlet pipe 63 diametrically on the higher side.
  • the drive 68 with a motor 64 rests on a pipe bridge 80. Loose surface water and loosened dirt are thrown into the trough 65 through radially surrounding sieve slots of a sieve cylinder 61 and can be discharged at the lowest point via an outlet 67.
  • FIG. 4 shows the assignment of the devices already described, the shower washing device according to FIG. 1, the screening device according to FIG. 3, the impact turbulence device according to FIG. 2 and an electronic device Data processing device that uses the individual devices according to the program and receives the process data required for this.
  • FIGS. 5 and 6 show examples of the formation of the work coverings of the working bodies 35 and 36, specifically in a cross-sectional view and in a top view. These are prism-shaped outward bumps that exert the effects already described on the grains.
