PROBLEM TO BE SOLVED: To provide a liquid spawn feeding valve device in which a residual amount of liquid spawn is reduced.SOLUTION: A liquid spawn feeding valve device 10 comprises an opening/closing valve 20 (opening/closing means) that opens and closes a valve hole 21A communicating a first room 24 and a second room 11. To the first room 24, liquid spawn feeding means 13 is connected, and to the second room 11, sterile air pressure-feeding means 12 (gas pressure-feeding means) and inoculation nozzle 90A are connected. The opening/closing valve 20 feeds liquid spawn 91 at the timing of liquid spawn inoculation via the first room 24 and the valve hole 21A and the second room 11 to the inoculation nozzle 90A by opening the valve hole 21A, and at the timing of liquid spawn discharge shuts the feeding of the liquid spawn 91 by closing the valve hole 21A. The sterile air pressure-feeding means 12 circulates sterile air 92 (gas) toward the inoculation nozzle 90A via the second room 11 at the timing of liquid spawn discharge, and discharges the liquid spawn 91A remaining at the second room 11 and the inoculation nozzle 90A from the inoculation nozzle 90A.
