Definitions

  • the invention relates to a method and an apparatus for treating grain. Before grinding the grains can be peeled. Numerous methods and devices have become known for carrying out the peeling process and for grinding the peeled grains.
  • the object of the present invention is to improve the method and the devices used for this purpose in such a way that, with a high degree of utilization, it is possible to adapt to the most varied types of grain. Furthermore, the invention has for its object to design the device so that they are designed to be space-saving and portable with simple and inexpensive manufacture.
  • the method according to the invention is therefore based on an empirically determined precise timing and temperature control, so that work is always carried out at temperatures below 30 ° C. This results in a perfect separation of the shell
  • the method according to the invention consists of several fractions, which is important with regard to the separation of the shells.
  • moisture content control is also important.
  • moisture enters the outer part of the grain and heat is generated to facilitate separation.
  • the time of mixing with moisture for example 15 to 30 minutes, is chosen so that the moisture can penetrate into the Testa layer, and this is very important.
  • a first and a second annealing process may be required to break up the grains, and a third short 5 to 10 minutes is required before grinding.
  • continuous tempering process used The maximum moisture content for the tempering before grinding is expediently 16%.
  • the method according to the invention ensures a clean grain or seed which is completely separated from dirt, hair, etc. This gives advantages in terms of storage and a long service life.
  • the peeled material is extracted and conveyed into an air stream in such a way that there is no contamination of the cleaned wheat and the grains, which are removed together with the fruit pulp.
  • the machine is applicable to a wide variety of grains and seeds including soft and hard wheat, durum wheat, barley, rye, malt barley, millet, African millet, milo, mung bean, sorhum and so on.
  • all grains must first be treated with moisture. During this process, the machine must be set by the operator, depending on the product being treated. Accordingly, the same speeds and humidity can be used for rye and wheat. Different speeds and moisture levels may be required for other grains, especially for delicate grains such as mung beans and lentils. All spherical grains are easier to peel, while prior conditioning is very important for the flat and elongated grains. In general, customer requirements will determine exactly what instructions are required for proper treatment.
  • the new system avoids the breakage of the grains and consequent loss compared to conventional grinding.
  • the grinding also results in a lower ash content.
  • a second tempering can also be dispensed with, because in conventional mills the Testa after the fruit skin layer prevents the moisture from the first tempering from penetrating into the grain
  • the removed fruit casings can be used economically as pure fibers in papermaking and in the chemical industry.
  • the quality of the fiber is high and the treatment is cheaper, resulting in a by-product of additional economic value.
  • the conditioning can be carried out by sensitive tempering under electronic control.
  • the casings can also be used for 100% germination for malt wheat, without any impurities, and this has potential application in laboratories, in the baking industry and in brewing beer.
  • the grinding device used in this process is of the disc mill design with certain modifications to the grinding surface and the rotation of the lower disc.
  • Both discs have two-stage grinding surfaces that are arranged in a groove of the same width.
  • the shape of the groove is tapered and there is a 3 mm gap between the grooves for air turbulence.
  • the second stage is also tapered at the beginning and 3 mm wide to compensate for the grinding process, as can be seen from the drawing.
  • the lower disc which rotates, has the advantage that the grains are not broken open during grinding, but rather a fractional treatment, which leads to an easy separation of the flour.
  • the corrugations prevent it from breaking open and there is a smooth separation of the fiber portion, which can later be removed by sifting.
  • the grinding process is carried out using specially designed teeth with a cutting tool that uses ordinary band saws as the material.
  • the upper edge of the saws is rounded in such a way that they do not injure the inner tissue of the grains during the grinding process.
  • the processing of the grains has to be gentle in order to avoid an increase in the ash content in the flour that is ultimately produced.
  • the effect of grinding is similar to that of a roller mill.
  • the upper disc is stationary while the lower disc is rotating.
  • the upper disc is adjustable so that the fineness of the ground material or the quality of the flour can be changed.
  • a three-point hitch is used during adjustment. If the user uses electronic suspension, electromagnetic or other systems can be used.
  • the adjustment of the opening between the panes is controlled from above by hand from the middle part of the pane.
  • the manual control takes place via a tube with a fine thread and a handle.
  • the three points of the suspension and the central adjustment are used to avoid lateral inclinations of the disc, so that a uniform contact of all surfaces of the disc that rotates is ensured during the work process. This is important with regard to uniform grinding and also with regard to adjusting the particle size of the product, which can then be viewed.
  • Rapid grinding can also be obtained for whole wheat flour or full flour of other types. All particle sizes can be adjusted by sieving.
  • the mill is suitable for dry grinding as well as for wet grinding and semi-wet grinding:
  • the grinder is not a pulverizer but an actual grinder. Air cooling by means of a self-generated air flow is provided. The speeds can be set in operation depending on the required product.
  • the moisture content can be up to 32%. Sesame seeds can also be roasted or unroasted treated in this way and dried after grinding.
  • the grinding device has a water reservoir so that water can be added during operation.
  • the grain can also be sprouted for a short time, which completely changes the biological structure compared to a dry treatment.
  • the water flow into the mill is fed from the feed side up at the same time as the wheat or the cereal grains.
  • the continuous flow of water prevents the grains from sticking to the grinding surface.
  • the water also keeps the grinding surface clean and creates a slurry, which is advantageous in terms of better grinding.
  • the porridge can be used for bread production or for other baking products and also for pasty goods.
  • the moisture content of the grain is increased to 42% and the product is ground to a consistency of a liquid slurry and then mixed with hard wheat semolina or hard wheat flour as it leaves the mill, depending on the type of product required.
  • the product is mixed in portions to 40% ground porridge and 60% by weight hard semolina. It is important that mixing takes place as soon as possible after grinding.
  • the shell part loses its color in the testa, which is not the case when hard wheat is used.
  • the fibers are kept clean and no addition of artificial core fiber is required.
  • the various mixtures used depend on the requirements of the market.
  • the bread is mixed with 60% hard wheat flour. Conventionally ground flours are used and the same applies to semolina in dough production.
  • the grain used In the wet grinding process, the grain used must be peeled beforehand so that the husks can be removed and the grain must be tempered to a maximum moisture content of 19%.
  • the removal of the shells is described as a separate inventive step.
  • the novel system of dough-bread and bakery products using the wet process has further advantages over conventional flour milling in that it increases the extraction rate by, for example, 15% and reduces the bran content, but the nutritional value of Product is obtained if, for example the bran content drops by 8%. Then the mixed dough is extruded and the taste is very pleasant. The entire germ and the fiber is maintained in the 40% porridge addition and also all proteins, riboflavins, thiamines, etc. remain in the mixture.
  • the finished dough product can be stored in a dry atmosphere for up to 6 months after extrusion. If the same is done in a dry process, then the maximum storage can be extended to 1 year. However, there is a slight difference in taste between the dry process and the wet process, with the wet process providing a somewhat more appealing taste. However, wet milling extraction is increased and this gives an important economic benefit to the producer and also benefits to the consumer.
  • the shelf life of baked goods is even extended by about 5 additional days compared to baked goods which use flour that has been ground in a conventional manner. No additives or chemicals are required to achieve this result.
  • the grain is conditioned using the same grinder with a rest period of 8 to 9 hours and then ground using 18% moisture or as the product requires. Coarse grinding may require subsequent sifting, while fine grinding may yield wheat flour and very fine flour, with no sifting required, and this can be used to produce pasta.
  • the taste is maintained along with all the nutritional values, the fiber content and the natural protein sources and the riboflavins, niazines and thiamines, just as is the case with a wet process.
  • the mower can be used for different seeds and grains and can be used for wet grinding, for semi-wet grinding and for dry grinding.
  • the grinder In all cases, the grinder must be cleaned thoroughly to prevent bad smells or contamination during subsequent production.
  • the device is made of hardened steel with sharp edges, so that together with air from a horizontal blower, wheat and grains are conveyed in smaller pieces for easier feeding after the larger teeth for easier grinding and after the finer teeth around the circumference of the disc to produce the same particle size of the products.
  • the smaller teeth also result in air turbulence that aids continuous movement of the product while it is being ground.
  • the shaft is located on the bottom part and is supported by two thrust bearings.
  • the ball bearings in the top two rows are arranged for the purpose of lateral movement control. If the shaft moves at high speed, complete control is required to avoid any axial damage. With such a structure, valve operation can be maintained provided that the lubrication is working properly and constant monitoring is being performed.
  • the tip of the teeth has such a radius that the test layer of the grain under the pericarp is prevented from breaking open.
  • the generation of ash is avoided during the final flour production.
  • the endosperm i.e. the inner tissue is separated from the sheep of the come without damaging the structure of the seeds.
  • the air cushion also supports the rotary motion of the grain product between the two disc grinding surfaces.
  • the grinding takes place with the various corrugations, i.e. sharp with sharp, blunt with sharp, sharp with blunt or blunt with blunt.
  • roller mills The advantage over roller mills is that the process can be carried out very quickly, with which it is possible to change the profile of the corrugations of the disks by removing the blades and replacing them in the same grooves with other types of blades. The whole process can be done in a few hours. If only one grinder is used, these changes can be made when necessary. If there are different grinding streams that have their own special grinding discs, the blades will not be replaced - changes may only be necessary in terms of speed and performance. Shipping safety, the time and cost of restoring the corrugations are significant for roller mills.
  • This type of grinding surface can also be used in possibly multi-stage grinding if there are no more than four stages, with two inner and two outer stages being provided. Volume performance is maximized when using two stages, and maintenance is easier.
  • a special tool is used to cut the shape of the teeth and band saws are used as the basic material, the thickness of which can be seen from the attached drawing. It is possible to use materials up to 3 mm thick for the blades to insert them into the grooves in segments instead of as continuous bands.
  • the grinder is used to crush minerals or fibrous materials, the teeth require different levels of sharpness. The customer's requirements will always be satisfied so that the desired material can be obtained.
  • the two angles of the corrugations or furrows are of great importance with regard to good grinding results and a low ash content.
  • the flatter angles of 25 ° result in greater pressure on the product.
  • the further angle of 55 ° results in a faster separation, especially for sensitive products.
  • the washers are used to effect a reduction when wet, only the "sharp versus sharp" combination is used and the results have no effect on the ashes.
  • the furrows or corrugations require sharp ends without a radius.
  • the devices according to the invention can be manufactured in different sizes. For example, units with a throughput of 150 kg per hour can be used for laboratory operation. This requires only a relatively small drive motor, for example 2 HP. Such units are easy to transport and can be used in a targeted manner, especially in underdeveloped countries.
  • FIG. 1 and 2 show a peeling device constructed according to the invention.
  • This has a hopper 10 for introducing the grain, which is followed by a screw conveyor 14 driven by a drive motor 20. From this, the ground material is transferred into the housing 16.
  • the housing consists of two parts, namely a bottom part and an upper part, which are connected on the left side according to FIG. 1 by a wall plate, which results in simple construction and simple maintenance.
  • a drum 18 with beaters or knives 19 is mounted with a horizontal shaft, the latter being arranged in two sections, the shorter knives lying on the left-hand side according to FIG. 1 near the inlet 15 in order to better distribute the grains in To ensure the longitudinal direction.

  • the knives 19 are arranged along surface lines of the drum or along helical lines.
  • the shorter knives on the inlet side have an angle of inclination of approximately 3 °, while the knives on the outlet side have an angle of 1 ° with respect to the end of the drum. In this way the grain movement is delayed during the rotation.
  • the drum 18 is enclosed in the upper half by a pimple metal screen 20 and in the lower part by a slotted metal sheet screen 22, which together form a cylinder. There is a 7 to 8 mm wide gap between the knives and the cylinder 20, 22 thus formed in order to avoid any impact. By the friction that occurs is treated by the tempered grains for the purpose of removing the fruit peel. Through the slotted metal sheet screen 22, the removed fruit casings fall onto the bottom of an outlet collecting vessel in which a screw conveyor 34 is arranged, which conveys the peels after the peel outlet 42.
  • the drum is carried by a main shaft 24 via a bearing housing 26 which has ball bearings 28.
  • the shaft 24 supports the drum 18 via a hub 30.
  • a dust protection ring 32 protects the end of the drum against the ingress of lubricating oil.

  • an annular collar 36 adjoins the drum, which is closed by a door articulated via a hinge 38, ie the door 40 closes the annular collar opening through which the peeled grain exits.
  • the grains are held back by the self-adjusting door 40 until all of the pods that are discharged through the outlet 42 are removed.
  • the peeled grain builds up in the ring collar, and grain is further conveyed in this, so that pressure is exerted on the door structure.
  • the hulled grain then arrives at outlet 44 and is discharged through a cascade retention plate to slow down the grains.
