Apparatus for producing fermented soybean meal

An apparatus for producing fermented soybean meal, the apparatus comprising:

• a solid-liquid separating part, which mixes raw material soybean meal and an extraction solvent and extracts soybean meal, and separately produces a remaining soybean meal and a soybean meal extract;
• a lactic acid bacteria culturing part, which produces lactic acid bacteria by putting inoculum into the soybean meal extract, and supplies the lactic acid bacteria to the solid-liquid separating part;
• a solid substrate fermentation part, which is selectively supplied with and mixes at least two of the remaining soybean meal supplied from the solid-liquid separating part, the raw material soybean meal supplied through a bypass, and lactic acid bacteria supplied from the lactic acid bacteria culturing part to produce a mixed material, and solid-substrate ferments the mixed material to produce primary solid substrate fermented soybean meal;
• and
• a drier, which dries the primary solid substrate fermented soybean meal supplied from the solid substrate fermentation part to produce secondary solid substrate fermented soybean meal,
• wherein the solid substrate fermentation part includes:
• a fermentation chamber, which is provided with an inlet, through which the mixed material is introduced, and an outlet, through which the fermented primary solid substrate fermented soybean meal is discharged, and ferments the mixed material to the primary solid substrate fermented soybean meal;
• a transfer conveyor, which is installed inside the fermentation chamber and transfers the mixed material and the primary solid substrate fermented soybean meal to an outlet side from the inlet;
• and
• a brush, which is provided at a lower side of the transfer conveyor in a width direction and brushes the primary solid substrate fermented soybean meal attached to the return side of the transfer conveyor,
• wherein the drier comprises:
• a fluidized bed drier, which dries the primary solid substrate fermented soybean meal of the solid substrate fermentation part at a first temperature;
• and
• a double mixing drier, which dries the primary solid substrate fermented soybean meal of the solid substrate fermentation part at a second temperature higher than the first temperature.
