A break roll machine wherein a timing belt (15) of a differential transmission mechanism (12) can be removed easily and wherein the removal of a roll pack module (8) from a machine frame and the installation of the new preassembled roll pack module (8) can be performed easily in a short time is disclosed. A cutout portion (25) is provided to one of a paired tension arms (17,17) so that the one tension arm (17) is rotatable around a pivot point (26) at an upper portion of the tension arm. As a rotary shaft (45) of an idler pulley (16) is released from the tension arm (17) through the cutout portion (25), the timing belt (15) can be removed easily. An air cylinder (31) is rotated freely by a first and a second linkage member (35,36). An operator can easily access to a bolt (43) located behind the air cylinder only by inclining the air cylinder at any desired direction.
摘要:
A pretreatment process in a flour milling method in which raw wheat grains are first polished and the polished grains are ground and milled for producing end flour, includes a first, a second, a third polishing step, and a step of adding water. In the first polishing step a pericarp (516) of each wheat grain is removed, in the second polishing step a seed coat (518) of each raw wheat grain is removed, and in the third polishing step a part of cell walls (530) of aleuron layer cells (519) that was in contact with the removed seed coat is removed so that a cell membrane (522) of the aleuron layer cell is caused to be ruptured and that a substance (521) in the aleuron layer cell is caused to be in a state which permits the substance to flow out. In step of adding water, by adding the water to each raw wheat grain, the substance (521) in the aleuron layer cells (519) is caused to flow out from the aleuron layer cells, resulting in producing a polished grain in a state in which the substance (521) in the aleuron layer cell (519) has been separated from each raw wheat grain. It is possible to increase the yield of the end flour collected by the subsequent grinding operation.

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. Thus, it is possible to reduce the time required for the tempering of the polished wheat grains and to adjust the second water addition based on the water content in the flour.

摘要:
A pearling machine has an abrasive type pearling roll assembly (29) which is formed by stacking a plurality of pearling rolls (29a) via intervening air blowing spacers. Stirring bars (40) are secured to the outer periphery of the individual pearling rolls (29a). Resistance bars (23) are provided on the inner surface of a vertical polygonal bran removal cylinder (20). With a cooperative function of the stirring and resistance bars (40,23), grains supplied to a pearling chamber (56) defined by the pearling roll assembly (29) and the bran removal cylinder (20) receive active spinning and revolution action. The grains thus receive uniform cutting action, and thus they are pearled uniformly. The vertical pearling machine permits optimum pearling of grains in dependence on the kind and character of the grains and is suited particularly to the pearling of tempered wheat with outer layer part having been made tough and inner layer part having been made soft.
