  • Patent number: 10240504
    Abstract: An amount of electric power consumption by a battery is reduced, and deterioration of a coil is suppressed by efficiently heating an injector and melting urea crystals at an early stage. A control device for a reducing agent injection device fills the device with a reducing agent at a start-up of an internal combustion engine and executes control for injecting the reducing agent into an exhaust passage of the internal combustion engine by the injector. The control device includes an energization control section that executes energization control in which, after an exhaust temperature of the internal combustion engine becomes equal to or higher than a specified threshold value, a temperature of the injector is increased by energizing the coil of the injector for a specified time and melting of the crystals of the reducing agent precipitated in the injector is promoted.

  • Patent number: 10196430
    Abstract: To provide effective use from a yeast extract residue, an excess of which is produced as a byproduct of yeast extract, or reduction in amount of the yeast extract residue. Also to obtain various useful substances. A cell wall lytic enzyme having no protease is allowed to act on a yeast extract residue, after which a heat treatment is performed at 70 to 80° C. for 10 to 20 minutes, thereby enabling separation into a fraction of primarily cell walls and a fraction of primarily protein. A yeast protein having a protein content of 60% or more is obtained from the fraction of primarily protein and, by subjecting the yeast protein to enzymatic degradation, a seasoning having a high amount of total nitrogen is obtained.

  • Publication number: 20180271138
    Abstract: [Problem] To manufacture a foaming member using a low-cost method having little environmental impact, in which the air bubbles in an air-bubble-containing product are enhanced and stability is improved, without imparting viscosity, coloring, flavor, cloudiness, odor, etc. Also, to provide an effective use of yeast cell residue generated as a byproduct of a yeast extract. [Solution] A yeast cell residue remaining after a useful extract is removed from a yeast is suspended in water, and is heated after pH adjustment, and then a supernatant is obtained by centrifugal separation. This fraction contains, in relation to the solid content, 35 wt % or more of protein and 30 wt % or more of dietary fiber, and is usable in the foaming member.

  • Publication number: 20170258097
    Abstract: [Problem] To produce a frozen bread dough improver that has an effect of improving rising of frozen bread dough, is highly safe, and tasteless, using a method that is low-cost and low in environmental impact. Also, to effectively use yeast cell body residue produced as a byproduct of yeast extract. [Means for Solving the Problem] Yeast cell body residue remaining after extracting useful extract from yeast is suspended in water and heated, after which the suspension is subjected to centrifugal separation and a supernatant is obtained. This fraction contains, per solid content, at least 45 wt % RNA, at least 5 wt % dietary fiber, and at least 10 wt % protein, and mannan content in the dietary fiber is at least 60 wt %. This can be used to improve rising of frozen bread dough.

  • Publication number: 20170196235
    Abstract: [Problem] To produce, with a method that is low-cost and has a low environmental impact, a cloudiness-inhibiting agent that is highly safe and has no taste which has a cloudiness-inhibiting effect in a tea beverage. Also, to make effective use of yeast cell body residue produced as a byproduct of yeast extract. [Means for Solving the Problem] Yeast cell body residue remaining after removing useful extract from yeast is suspended in water and heated, after which the suspension is subjected to centrifugation to obtain a supernatant. This fraction has an amount of RNA content per solid content of the yeast extract of at least 50 wt %, dietary fiber content of at least 5 wt %, and protein content of at least 10 wt %. Mannan content is at least 60 wt % of the dietary fiber. This fraction can be used to inhibit cloudiness for a tea beverage.

  • Publication number: 20170042201
    Abstract: An antiflocculation/settling agent is manufactured with a method having a low cost and low environmental impact, the agent having a high level of safety and no taste, and having an inhibitory effect on flocculation/settling of a food or beverage. Also, to make effective use of yeast cell body residue produced as a byproduct of yeast extract. Yeast cell body residue remaining after removal of useful extract from yeast is suspended in water and heated, after which the suspension is subjected to centrifugal separation and supernatant is collected. This fraction contains at least 15 wt % RNA content per solid content, at least 10 wt % dietary fiber content, and at least 15 wt % protein content, and mannan makes up at least 50 wt % of the dietary fiber. This fraction can be used as an antiflocculation/settling agent in foods and beverages.

  • Patent number: 8522530
    Abstract: A reducing agent injection valve abnormality detection device for detecting clogging of a reducing agent injection valve in a reducing agent injection device has a pressure detection component that detects the pressure inside a supply path based on a sensor value of a pressure sensor, a pump control component that fixes the output of a pump in a state where the pressure inside the supply path has become a value in a predetermined range, a reducing agent injection valve control component that opens the valve for a predetermined amount of time in a state where the output of the pump has been fixed, and a clogging determination component that determines the extent of clogging of the reducing agent injection valve by comparing, with plural threshold values, the pressure, or a pressure drop quantity, inside the supply path when the valve has been opened for the predetermined amount of time.
