Definitions

  • the present invention relates to a grinding process which can be used universally for the production of flours, meal, and at most flakes of suitable quality from various types of cereals and crops.
  • the invention relates to a special installation for operating the grinding method according to the invention.
  • the grinding process should also allow a longer shelf life of the ground material.
  • Another object of the invention is to provide a system for operating the grinding method according to the invention which is particularly inexpensive to purchase and maintain and simple to operate, so that it can be operated by merely trained personnel.

  • Figure 3 A perspective view of a system according to the invention, which is housed in a 20 foot container.
  • the regrind to be processed is emptied from a storage silo or from bags and poured into a pouring channel 1 then brought from a cup elevator 2 into a universal cleaning machine 3.
  • the purpose of this cleaning machine 3 is to separate dust, stones and other impurities from the ground material.
  • about 2-3% of water is added when passing through the now switched on power paddle screw 4.
  • the product passes through the machine without the addition of water, since for reasons of durability the flour moisture should not exceed 13.5% in this case.
  • the subsequent stand-off cells 5 must be dimensioned so large that there is sufficient time for the network water to penetrate the ground material and penetrate it.
  • this machine 10 By adding water to the grain flow and then rubbing the grains with one another in the agitator cylinder, this machine 10 brings about a simultaneous, intensive penetration of the water through the grain shell and a formation of the grains. All machines and conveying elements in the area of cleaning and peeling equipment are aspirated by central aspiration for the purpose of dust and shell removal. All suction lines in this area lead to a separating cyclone 25 with a built-in low-pressure fan 26.
  • the regrind passes through a further cup elevator 11 into a small storage container 12 and from there, after a short dwell time, through a feed device 13 to the primary crushing rollers 14.
  • the primary crushing roller 14 has the task of the grain break into sections in order to separate coarse shell parts and the fatty seedling from the other regrind at the downstream sorter 15, primarily when grinding maize.
  • This sorter 15 works by means of vibrating flat screens and can also sort out semolina from the broken ground material. However, if you do not want to sort out partial products, such as when producing whole flour, you can simply go through this machine with no effect by simply removing the sorting sieves.
  • the adjoining separating device 16 consisting of a magnet and a heavy goods trough, has the task of separating iron parts and other foreign bodies.
  • the ground material is comminuted to the desired particle size in a single pass.

  • the baffle pins 32, 33 on each annular disk 29, 30 are arranged in concentric circles with respect to the axis 31, such that, starting from the axis 31 in the radial direction, a ring of baffle pins 32 of the one annular disk 29 is aligned with those 33 of the alternate alternate washer 30 at small intervals.
  • 180 impact pins can be arranged in such concentric circles on each annular disk 29, 30.
  • the washer 29 has three, the washer 30 four concentrically arranged rings of impact pins.
  • the speed of rotation of the impact pins is, depending on the ring in which they are arranged, approximately between 50 to 160 m / s.
  • the two ring disks 29, 30 now run in opposite directions to one another, so that the individual impact pins 32, 33 of the two ring disks 29, 30 pass each other barely.
  • various ring disks with correspondingly spaced baffle pins are used.
  • the regrind comes from above through a feed to the center of the grinding disks, where it is broken up by the rotating pins, going from the inside out. It goes without saying that the outer impact pins are subject to greater wear, due to their higher speed than the inner impact pins.
  • the speed and the amount of impingement of the impact pin mill 17 are preferably designed for a fineness with a coarse grain of the flour particles in the range between 50 and 300 ⁇ , preferably between 100 and 250 ⁇ .
  • the coarse particle sizes of the shell particles amount to 1 to 4 mm, preferably 1 to 2 mm.
  • the millbase passes through a suction air stream 18 into a separator cyclone 19. There, the product is separated from the conveying air, which goes to the filter by means of the high-pressure fan 24.
  • the regrind falls through a separating lock 20 onto a folding box 21, where the finished product is already obtained during full flour production.
  • the sieve transition (bran) is still fed to the bran spinner 23 in order to increase the yield for extract flour.
  • the flour particles adhering to the shells are thrown off and filter dust from the air filter 24 is returned to the separator cyclone 19 through a separate suction line, thereby ensuring a maximum yield.
  • the system according to the invention can be built inside a container that can be transported by road, as shown in FIG. 3, or can be accommodated in several such containers that can be connected to one another in such a way that a system with a continuous flow of regrind is formed.
  • An entire mill with a daily capacity of 20 tons (800 to 1000 kg / hour) can be accommodated in two 20-foot containers.
  • a mill can then be adjusted to a certain extent in the modular system in terms of capacity, and moreover, when several smaller units are operated, technical malfunctions on a single unit have a less fatal effect, in that only a fraction of the capacity fails, whereas in the event of a malfunction in a large mill, the entire system comes to a standstill.
  • the containers can easily be loaded onto trucks, which makes the system according to the invention mobile and can be moved to the respective locations of its need. All that is required to set up the containers is a foundation or sufficient floor mounting.
  • the system can be put into operation within one to two weeks after installation. Operation and maintenance is so simple that it can be taken over by one or two trained assistants. Neither proven millers nor mechanics are required to monitor and operate the system.
  • the plant according to the invention and the method operated with it make it possible not only to use a certain type of grain, for example wheat, but also others such as maize or Process sorghum. Whereas three different plants were previously necessary for these three types of grain, wheat, corn and sorghum, the plant according to the invention practically combines three mills in one unit.
  • the investment costs for a system according to the invention measured in terms of its capacity, are less than half in comparison to a conventional stationary mill.
  • the system can also be set up in a few days.
  • To adapt the system to the processing of a specific type of grain all that is required is to use the desired sieves with simple manipulations and to control the flow of regrind accordingly by means of the built-in switches. Impurities and foreign bodies are additionally separated from this by suction of more controllable starch, adapted to the respective regrind.
  • the whole flours milled according to the method according to the invention have a significantly higher durability than conventionally milled flours. If the moisture content is no more than about 12%, the whole flours can be stored in dry and cool stores for up to 9 months, in contrast to about 1 to 2 months with previous full flours.

Abstract

Le procédé pour la production de farines, éventuellement de flocons de qualité appropriée ou de moutures de différentes variétés de céréales et de produits agricoles, comporte les phases successives de traitement suivantes: humidification, pause, épluchage par voie sèche au moyen d'une éplucheuse à meule d'émeri (9) ou bien épluchage par voie humide au moyen d'une machine à éplucher par voie humide, prébroyage au moyen d'une paire de cylindres broyeurs (14) et triage au moyen de tamis plans. Ensuite on procède à un broyage en une seule passe au moyen d'un broyeur à chocs (17) d'un seul étage de broyage. Le broyeur à chocs (17) présente plusieurs anneaux constitués de broches de percussion, lesquels tournent à contre-sens à une vitesse périphérique de 50 à 160 m/s. L'opération de mouture proprement dite est suivie éventuellement d'un tamisage effectué au moyen d'une machine à tamiser à tambour (22). Toutes ces phases de traitement sont réalisées dans une installation compacte, laquelle tient dans un conteneur transportable par route ou bien dans plusieurs conteneurs transportables par route et fonctionnellement assemblables.
