  • On-line moisture control method for powdered or granular materials and a system to execute the method
    Patent number: 5274931
    Abstract: An on-line moisture control method for powdered or granular materials and a related system to practice the method. A fixed amount of materials are sampled by a material sampling means, transported into a heat treatment chamber having an airtight heating part, heated in the heat treatment chamber while an inert gas is supplied therein, and the weight measured by a weight measuring unit. The moisture generated by heating the materials is sent to a moisture measuring unit together with the inert gas. An operation unit receives the weight value measured by the weight measuring unit and the titrated value measured by the moisture measuring unit, and calculates the moisture content of the materials and displays the value.
    Type: Grant
    Filed: May 26, 1992
    Date of Patent: January 4, 1994
    Assignee: Kabushiki, Kaisha, Matsui, Seisakusho
    Inventors: Hiroshi Ogiri, Kazue Murata, Sadaaki Tanaka
  • On-line drying control method for powdered or granular materials and a system to execute the method
    Patent number: 5165180
    Abstract: An on-line drying control method for powdered or granular materials and a related system to execute the method. A fixed amount of materials stored and dried in a drying means such as a hopper dryer is sampled, transported into a moisture measuring/operating station wherein the sampled materials are heated in a heat treatment chamber and the moisture content is calculated by an operation unit. The moisture content is sent to a temperature controller to control the temperature of the drying means so that the obtained moisture content corresponds to a predetermined moisture content while comparing both moisture contents.
