  • As flour semolina or haze known on the principle of high milling.
  • the millbase is often roll-milled and repeatedly sieved.
  • a material to be ground is passed over double-roller grinding stages, wherein the material to be ground is guided over at least two such milling stages and is performed without screening between the individual stages and is then sighted at the Doppelvermahlung respectively.
  • WO 2010/000811 A1 For example, there is known a method of making flour and / or semolina using a variable bed, soft bed roller mill.
  • the nip sets depending on the amount and the type of grain to be ground and the set pressure exerted on the rollers in the direction of the nip, a.
  • this known method and the corresponding device have the disadvantage that larger particles are not reliably ground in the material to be ground and it may come to vibrations of the rollers due to the processed material to be processed, which often also includes particles in the size of the nip.
  • heat is hardly added to the material to be ground in such high-bed roller mills, which is desirable in the production of certain types of flour, however.
  • a further object of the present invention is also to provide a device and a method by which flour from Good can be produced inexpensively and energetically favorable, wherein in particular also sufficient heat is supplied into the flour during grinding.
  • the inventive method for producing flour and / or semolina from good, in particular cereals, cocoa, sunflower seeds and rice or any combination thereof thereby comprises the following steps: Good is fed from a bed in a feed opening of a bed of high-quality rollers.
  • the good bed roller mill comprises a first roller and a second roller, wherein at least one of the two rollers is movably supported in a direction substantially perpendicular to the direction of rotation of one of the two rollers for setting a grinding gap between the two rollers.

  • the bed consists of particles with a size distribution and comprises in particular one of the following types or mixtures thereof: good, semolina, shell parts.
  • the grinding gap is set in particular fixed and / or the damping is adjusted so that a first subset of the bed containing finer millbase forms a packed particle bed in the grinding gap.
  • the adjustment is made such that individual particles of a second subset of the bed containing coarser millbase are in contact with the first roller and the second roller of the good bed roller mill.
  • a grinding of the bulk material in the good bed roller mill in ground product. After grinding, the milling product is discharged through a discharge opening.
