Patent number: 5544823Abstract: The invention is directed to a new method for producing milled grain products such as flour, semolina, middlings, etc., wherein the material is repeatedly ground by means of rolls and sifted with the system of advanced milling. It is suggested that the material be guided again at least twice via double-roll grinding stages with sifting between the double grindings, wherein the material is sifted in each instance following the double grinding. In an especially preferred manner, a corresponding new mill with at least two double-grinding passes is preferably constructed as an 8-roll mechanism (70). In an especially preferred manner. the new mill comprises a combination of eight- (70) and four-roll mechanisms (142, 151). A screening surface which is at least 20 to 50% larger is used for the double grinding.Type: GrantFiled: December 19, 1994Date of Patent: August 13, 1996Assignee: Buehler AGInventors: Werner Baltensperger, Christian Lippuner

Patent number: 5368239Abstract: In an apparatus for producing milled grain products by means of repeated roll grinding and sifting of specific product fractions, the material to be milled is at least partially guided via double-grinding passes without intermediate sifting. An eight-roll mill is used for this purpose, which eight-roll mill is constructed as a double unit with two roll pairs arranged at a distance one above the other and can be used in quantity in a grain milling system or also in combination with single-grinding passes constructed as four-roll mills. Compared with the use of known four-roll mills, the economic efficiency of a mill is accordingly improved while completely retaining the adaptability of the mill to specific grinding tasks, the quality of the material to be milled and/or the ability to monitor the grinding process.Type: GrantFiled: August 31, 1992Date of Patent: November 29, 1994Assignee: Buehler AGInventors: Werner Baltensperger, Robert Linzberger

Patent number: 5165608Abstract: The invention is directed to a new method for the production of a starch raw material for subsequently obtaining pure starch from wheat, rye, corn or barley. Fractions of starch which is damaged as little as possible are produced by means of roller grinding and sifting devices. The material is ground repeatedly and sifted with the system of advanced milling, wherein it is suggested in particular to guide the material two to five times via double-grinding stages without sifting between the double grindings. Sifting is effected subsequent to the double grinding. The invention also concerns a starch milling system which comprises two to five double-grinding passes with two grinding-roll pairs which are connected one after the other and are preferably constructed as an eight-roll mill.Type: GrantFiled: February 7, 1992Date of Patent: November 24, 1992Assignee: Buehler AGInventors: Werner Baltensperger, Christian Lippuner

Patent number: 4881689Abstract: In a method for setting the spacings of grinding rollers (2, 2') in roller frames (1) of a cereal milling plant, the roller frames are in each case followed by a screening system (14), from which a test signal is tapped and supplied to a computer (7), which compares it with a stored desired value and in the case of a variation brings about an automatic adjustment of the spacings of the grinding rollers by means of a control signal and adjusting means (4, 5). The test signal is only derived from the screen reject material (17) or screenings (18) of screening system (14) and is only supplied from certain selected key passages to computer (7). In a cereal milling plant for performing this method, a momentum weight measuring system (24, 29, 30, 31) for the continuous determination of the sifting work is associated with the gyratory sifter or sifters (14).Type: GrantFiled: November 4, 1986Date of Patent: November 21, 1989Assignee: Gebrueder Buehler AGInventors: Christian Lippuner, Werner Baltensperger
