Patent number: 5773066Abstract: Raw wheat grains are polished after being subjected to a first water addition and being tempered, and the polished wheat grains are ground after being subjected to a second water addition and being tempered. The first water addition is to cause the raw wheat grains to have a water content of 12-14%. The tempering of the raw wheat grains is performed for 16-36 hours so that the water sufficiently penetrate into the inside of the raw wheat grains. The method of flouring includes the steps of measuring a water content of the flour obtained by the grinding of the grains, comparing the amount of the measured water content with a predetermined target water content of the flour, and adjusting the amount of water to be added during the second water addition if there is a difference between the measured water content and the predetermined target water content.Type: GrantFiled: February 7, 1997Date of Patent: June 30, 1998Assignee: Satake CorporationInventors: Satoru Satake, Shigeharu Kanemoto, Nobuhiro Matsumoto, Akihiko Kato, Yoshihiro Tokui, Satoru Takashita, Kaoru Shitadera, Hiroyuki Maehara
