Title:
WOOD CHIP FERMENTATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/011980
Kind Code:
A1
Abstract:
The present invention comprises: chip fermenters 11 that are filled with wood chips serving as a heat source and that cause the wood chips to ferment; temperature sensors 11a that are provided inside the chip fermenters 11 and measure the temperatures inside the chip fermenters; heat energy extracting pipes 12 that are disposed inside the chip fermenters and extract fermentation heat from inside the chip fermenters; a pump unit 13 that supplies a medium to or removes a medium from the heat energy extracting pipes 12; stirring blades 14a that stir wood chips 10a filled into the chip fermenters 11; and discharge conveyors 15 that are disposed below the chip fermenters 11 and discharge fermented material. The stirring blades 14a are disposed between the heat energy extracting pipes 12 and rotating surfaces thereof are parallel to the heat energy extracting pipes 12. The bottom surfaces of the chip fermenters 11 are formed in an arc shape so as to follow the rotating outer peripheral surfaces of the stirring blades 14a. A plurality of the temperature sensors 11a are installed in a vertical direction inside each chip fermenter. Control of opening/closing valves of the heat energy extracting pipes 12 is performed on the basis of temperature information from the temperature sensors 11a.
