    Abstract: To provide a drying method for processing material and a horizontal rotary dryer allowing easy performance of mass processing of the processing material and enabling size reduction by improving drying performance of the dryer. In a drying method for processing material in which a horizontal rotary dryer provided with: a rotating shell having a feed port for processing material on one end side thereof and a discharge port for processing material on the other end side thereof, and capable of freely rotating around an axial center; and a group of heating tubes through which a heating medium passes, provided within the rotating shell, and configured in a manner that the processing material is lifted up in a rotational direction by the group of heating tubes in accordance with the rotation of the rotating shell, is used, and the processing material is dried, through indirect heating, by using the group of heating tubes in a process of feeding the processing material to the one end side of the rotating shell and discharging the processing material from the other end side of the rotating shell, the rotating shell is rotated to make a critical speed ratio α defined by the following expression 1 and expression 2 become 30 to less than 100% to dry the processing material, Vc=2.21D1/2  Expression 1 α=V/Vc·100  Expression 2 wherein Vc indicates a critical speed (m/s), D indicates an inside diameter (m) of the rotating shell, α indicates the critical speed ratio (%), and V indicates a rotation speed (m/s).

    Abstract: A biomass treatment device and a biomass treatment method, in which contamination is prevented and a final product can be highly concentrated. The biomass treatment device includes a pretreatment device for pretreating a biomass, a slurrying device for slurrying the pretreated biomass, and a saccharification device for saccharifying the slurried biomass with a saccharifying enzyme. A return line for returning a part of an internal fluid in the saccharification device to the slurrying device is provided, and the pretreated biomass from the pretreatment device and the internal fluid returned through the return line are mixed in the slurrying device so as to generate biomass slurry.

    Abstract: To provide a drying method for terephthalic acid and a horizontal rotary dryer allowing easy performance of mass processing of the terephthalic acid and enabling size reduction by improving drying performance of the dryer. In a method of drying terephthalic acid by using a horizontal rotary dryer, a rotating shell is rotated to make a critical speed ratio α defined by expression 1 and expression 2 become 17 to less than 80% to dry the processing material, Vc=2.21D1/2   Expression 1 α=V/V c·100   Expression 2 wherein Vc indicates a critical speed (m/s) of the rotating shell, D indicates an inside diameter (m) of the rotating shell, α indicates the critical speed ratio (%) of the rotating shell, and V indicates a rotation speed (m/s) of the rotating shell.

    Abstract: Pressurized fluidized furnace equipment includes a fluidized bed furnace (1) that pressurizes combustion air (B) and combusts a material to be treated (A) while fluidizing the same; an air preheater (3) that exchanges heat between a combustion exhaust gas (C) discharged from the fluidized bed furnace (1) and the combustion air (B); a dust collector (4) that removes dust from the combustion exhaust gas (C); and first and second superchargers (5, 6) to which the combustion exhaust gas (C), having undergone the heat exchange in the air preheater (3) and the dust removal in the dust collector (4), is supplied to generate compressed air (D, E). The first compressed air (D) generated in the first supercharger (5) is supplied as the combustion air (B) to the fluidized bed furnace (1) by way of the air preheater (3), and the second compressed air (E) generated in the second supercharger (6) is made to have a higher pressure than that of the first compressed air (D). Accordingly, it is possible to prevent the equipment from having more superchargers than is necessary for normal use although a plurality of first and second superchargers are provided, and to efficiently use the surplus combustion exhaust gas.
