Three-roller mill with three grinding passes.

Patented in the German Empire on June 26, 1919.

The present invention relates to a three-pass malt mill in which The malt is pre-crushed in the first grinding cycle and then through a suitable separator is broken down into three components, namely flour, semolina and husks, of which the last two products in the second and third grinding of a further Processing. In the previously known malt mills,

ig six, but at least five grinds used to make three grinds. Fig. 1 of the drawing shows the size of the known malt mills with three passes. The P.uchr η .1 /, Gr, Sp mean the passage flour, semolina and husk. ; S in the grinding pass I proceeded to a sieve device, which separates three parts, namely into semolina,: cn and flour. The grits Cr reach the final passage II and the husks Sp in passage III to the final approach, and the flour M is boiled out as a finished product. The aim of the new invention is to bring this grinding, which usually requires six, but at least five, rollers and one sieve, to through with only three s and one sieve device. The device required for this is shown in Figs. 2 and 3. In the Dreiwalzcusystem the passage 1 is formed by the first and second e, the milling passage II by the wide and third and the milling passage III also by the second and third; c. The division of semolina and food takes place in such a way that each for itself is between wide and. third roller get so: that the middle part of both rollers as, passage II picks up the grit, | : nd the two end parts of the two Wal-jil Mill Passage III are intended for Passage I husks. This is made possible in the following way, in Fig. 2 and 3 the pre-meal reaches the sieve I, and the husks 1, which are passed through the channel k to the i 5, are pushed off. This channel k is j partition walls in five compartments i t, of which the compartments kr and k * \ are covered in a roof shape, so that the j en reach the sieve 3 only through the compartments Ic1, \ d ft5. This | has at the end j Icche b1 arranged at an acute angle (Fig. 3), which -the husks' fen, to get to the end sections of the whale- and 3, which form the grinding duct ITT. If diarrhea through sieve 1 falls onto sieve 2, the grit is almost thrown off, semolina gets under from sieve 2, the guide plates c through the j Ic Ic · and A · 1 onto sieve 4. This sieve wci leilbleche />. which direct the grits to the littleren part of the rollers 2 and 3, it forms the grinding passage II. The diarrhea through sieve 2 is flour, which flows through lateral Umfülirkanäle that it around the sieves. Guide 3 and 4 around, come to the ejection. It combines with the diarrhea through sieve 4, which is also flour. From Fig. 2 and 3 it can be seen that the third roller in the middle part, which represents the grinding passage II, is kept slightly larger in diameter than the diameter at the ends which form the grinding passage III. The purpose of this is to create a larger grinding passage for the husks, which is necessary for better conservation, while the semolina, on the other hand, has a narrower grinding passage in order to be able to carry out their finer grinding. The middle part can also be corrugated at this point. The distribution of the semolina and husks between the rollers 2 and 3 can of course also take place in any other way, so that with the middle division the husks on the left and the semolina on the right or vice versa between the rolls, or that the semolina in two compartments outside and the husks are ground together in the middle part. Patekt claims: 1. Malt mill with three grinding passes and an intermediate sieve device, which divides the pre-meal into flour, semolina and husks, characterized in that the three grinding passes formed by three rollers and the - zen and the tailings \ ^r orschrots be passed through the screening apparatus so that a separate grinding is effected both at the same time between the last two rolls. 2. Execution of the three-roller malt mill according to claim i, characterized in that the separate grinding the husks and semolina takes place in such a way that the semolina in the middle part of the grinding rollers, and the husks on the get both end parts of the same grinding rollers for post-grinding. 3. Execution of the three-roller roller mill according to claim 2, characterized in that the third roller is on the one intended for the passage of the grit Part has a correspondingly larger diameter in order to be able to grind the semolina to a large extent to protect the husks as much as possible, whereby the thickened part of the roller can be corrugated. 1 sheet of drawings.
