Conventional fermentation apparatus for microbial fermentation mainly relates to the use of a liquid medium, and in the case of fermentation to a solid or semi-solid medium requires a large amount of oxygen supply, this requires a large space, this For this reason, outdoor fermentation was usually common.

However, in the case of such outdoor fermentation, it is not possible to prevent the invasion of not only certain microorganisms subject to fermentation but also other microorganisms present in the atmosphere, and thus there is a risk of contamination.

Generally known solid or semi-solid medium fermentation targets were mainly for fermentation of industrial wastes such as various food wastes and herbal extracts, fermentation for the manufacture of fertilizers, fermentation for livestock meals such as poultry meal, pig meal, milk powder, etc. As described above, contamination by the microorganisms in the air during the outdoor fermentation process is not a serious problem, but when used for the purpose of food production through fermentation, etc. may cause a fatal problem.

And a means for heating the fermenter and a stirring means for mixing the introduced organic material and the microorganism carrier, wherein the stirring means has a ribbon screw and a paddle wing on a horizontal axis of rotation. However, this device is a device for decomposing treatment of manure and waste, and has a horizontal structure in which the ribbon screw and the paddle blades rotate in the same direction, so that oxygen supply and mixing of the medium are not smooth. Have

Further, Japanese Laid-Open Patent Publication No. H5-43369 describes a mixture stirring device composed of a swing structure in which the vertical actuating structure portion of the spiral wing structure is free to move in the vertical direction, but this describes the spiral blade structure in the lateral direction.
