In the apparatus disclosed in Japanese Patent No. 38886, a screw conveyor having a tip inserted into the processing tank is installed in order to take out the dried product from the processing tank.

[0005] JP-A-54-54878 and JP-A-Hei-4
Japanese Patent Application Laid-Open No. 238886/1990 discloses that since the treatment tank has a closed structure, hot air and hot air supplied into the treatment tank and gas (gas) generated by fermentation and drying of the raw material are discharged. Requires exhaust piping.
In each case, the processing tank is installed so that the axis is horizontal, and in order to be able to stir the raw material satisfactorily, the raw material to be charged into the processing tank must be below the rotation center. In addition to the disadvantage that the amount of raw material that can be put into the tank is reduced with respect to the volume of the processing tank, the efficiency of drying is poor because the hot air or hot air is ejected at the upper part of the processing tank. In addition, hot air is supplied to the treatment tank to promote fermentation and drying. This hot air generally uses exhaust gas after burning such as a petroleum burner, and the oxygen required for fermentation is very low. It was in an oxygen-deficient state and had a drawback that fermentation could not be carried out sufficiently.

[0006] Further, in the apparatus described in Japanese Patent Application Laid-Open No. 54-54878, the raw material is stirred by a spirally-provided stirring blade, and when the tank is rotated in one direction, the raw material moves to one side. Therefore, the helical direction of the stirring blade is made different on one side and the other side in the axial direction, and the tank is rotated forward and reverse to uniformly knead, so that the operation method is complicated. Japanese Patent Application Laid-Open No. Hei 4-238886 discloses a method in which hot air is caused to flow into an upper portion of a processing tank once, and then sucked by a hot-air circulating blower and ejected from a jet nozzle. Has an open exhaust duct, the amount of hot air flowing into the processing tank is directly exhausted from the exhaust duct, and the thermal efficiency is very poor. And what is described in JP-A-4-238886 is
Although stirring is performed by a ribbon-shaped stirring device, it takes a long time to dry because the stirring is not performed efficiently.
