  • Patent number: 5798466
    Abstract: By a load detector, a magnitude of a dynamic load, depending on a downward-flow impact of a particulate material flowing through a flow passage, is measured, and also a magnitude of a static load, corresponding to a total amount of the particulate material flown through a predetermined position for a predetermined time period, is measured. A value of a dynamic load-type flow rate of the particulate material, corresponding to a measured value of the dynamic load, is calculated from the measured value of the dynamic load by a first calculation formula, and also a value of an actual flow rate of the particulate material is calculated from a measured value of the static load during the predetermined time period by a second calculation formula. A correction factor for bringing the dynamic load-type flow rate value, depending on the difference of the particulate materials, into agreement with the actual flow rate value is found.

  • Patent number: 5773066
    Abstract: 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.

  • Patent number: 5669511
    Abstract: A grain sorting apparatus includes a conveyor belt mechanism for conveying grains, fed by a feed mechanism onto a conveying surface separately from each other at an upstream region with respect to a conveying direction, to a downstream end so that the grains are discriminated and sorted by a discriminating mechanism and a sorting mechanism when dropping from the downstream end along a predetermined path, the belt mechanism being disposed so that the conveying surface thereof declines as going downstream with respect to the conveying direction to prevent the grains being carried by the belt mechanism from rolling toward the upstream direction on the conveying surface of the belt mechanism. It is therefore possible to prevent the grains from rolling on the conveying surface of the conveyor belt mechanism toward the upstream direction relative to the conveying surface of the conveyor belt even when a conveying velocity of the conveyor belt mechanism is high.
