Definitions

• the invention relates to a method and a device for cleaning cereals, in particular for reducing pollutants in near-surface shells or layers of cereal grains, such as wheat.
• Cereals for example wheat or rye
• CH-A-640750 describes a process in which wheat is subjected to dry cleaning, including scrubbing and aspiration. The wheat is then wetted and stored in stand-off cells for a few hours. After standing up, the wheat is peeled directly before the first grinding passage. The peeling can be preceded by conditioning. This depends on the degree of peeling and / or the abrasion of the grains after wetting and standing.
• the exposed bran shell is to be removed, the grains being moistened before conditioning for preparation for grinding so that the outer layers of the husk are conditioned without swelling, and subsequently (within The grains are subjected to several rubbing processes for 1 to 5 minutes to remove the outer shells and grinding processes to remove and separate the inner shell layers.
• the invention has for its object to develop a method for cleaning grain with which the cleaning of grain, in particular wheat can be further simplified.
• the peeling can be followed by grinding and possibly polishing of the grain surfaces.
• horizontal, in particular mechanical conveying elements should be largely avoided in the mill.
• the peeling process according to the invention can be used for common wheat as well as for durum; a lower pollutant content of the grains to be ground is achieved.
• Bran contaminated with pollutants can be subjected to targeted processing and recycling.
• intensive grinding or abrasion of the grain surface is possible. This procedure influences the flour quality and changes the grinding.
• Another object is to provide a facility for cleaning grain, especially wheat. This object is achieved with the features of claim 7.
• Fig. 1 a process diagram Fig. 2: a peeling machine.
• Cleaned as well as wetted and stale wheat passes from unspecified cells into a dosing device 21 and from there via a magnet 23 into a network or.
• Conditioning unit 22 where the required moisture (shell conditioning) is set (approx. 2% water addition in the example).
• the network unit has a network screw, but alternatively two screws are also possible.
• the wetted wheat is guided over a magnet 23 and reaches the peeling machine 20, where the wheat is peeled with a degree of peeling of approx. 4%. An air stream flows through the wheat during peeling.
• the peeled wheat passes through a further magnet 24 ' into a vertical grinding machine 25, for example a stone grinding machine, and from there via a magnet 24 " into a polishing machine 26.
• the wheat cleaned and prepared in this way is temporarily stored in a depot 27 and fed to the grinding via a metering device 28, starting with the first meal.
• the diarrhea of the peeling machine 20 and the light product obtained in the aspiration are separated, ground separately, pressed into pellets and, for example, used for fuel.
• the diarrhea from grinding and polishing is also processed in this way.
• the stator 1 of the peeling machine 20 has a housing 2, which surrounds a rotor 3 mounted therein and is mounted on a frame and is open at the bottom by a subsequent outlet trim 4. The diarrhea from peeling flour and shell parts is removed through these outlet trimmings.
• the wheat grains From a product inlet 5, the wheat grains reach the processing zone 6 via a feed screw 10. During the peeling, the wheat grains are guided against an adjustable accumulation device 7 in order to form a specific processing pressure in the processing zone 6. The peeled wheat grains leave the processing zone 6 through an adjustable outlet opening 8 and the peeling machine 20 via an outlet 9.
• the processing zone 6 is formed on the stator side by two screen baskets, so that they completely envelop the rotor 3 in the axial direction.
• the rotor 3 is formed from a chill roll with a hollow shaft.
• the roller includes slots which are evenly spaced from one another on the circumference of the roller and which extend over the entire length of the processing zone 6.
• the sieve baskets consist of individual sieve plates.
• the hollow shaft has a plurality of openings for the escape of air.
• the air continues through the slots in the roller into the processing zone 6 and helps Separate shell parts etc. from the wheat grains.
• the air is pressed into the hollow shaft by a fan.
