    Abstract: Various defects that occur when a water-repellent or defoaming layer is formed on a contact portion of a liquid container are reduced. A method for manufacturing a liquid container for containing a liquid includes: (a) preparing a pre-formation liquid container in which a surface layer has not been formed; (b) bringing an aqueous solution obtained by adding water to one of a defoaming agent and a water-repellent agent into contact with a surface of a contact portion with which the liquid is brought into contact, of the pre-formation liquid container; and (c) drying, after the step (b), the contact portion to form the surface layer that is formed of one of the defoaming agent and the water-repellent agent on a surface of the contact portion.

  • Patent number: 9511371
    Abstract: A bran removing wire-mesh tube includes: bran removing wire-mesh tube parts 28 divided in more than one in a circumferential direction in planar view; and a plurality of support pillars 33 erected at intervals in the circumferential direction to respectively fix both side edges of the divided bran removing wire-mesh tube parts 28. Each of the support pillars 33 is provided with an elongated resistor 34 that suppresses grains from moving in the circumferential direction along with rotation of grinding type grain cleaning rolls 26. The resistor 34 is urged by an elastic member 37 to a position at which the resistor 34 protrudes toward the inside of a grain cleaning chamber 30. Further, the resistor 34 is provided so as to be movable in a radial direction to a position farther from the grain cleaning chamber 30 due to resistance from the grains.
