Background

Solid state fermentation is a fermentation mode of microorganisms on a solid substrate without or basically without free water, wherein gas, liquid and solid phases coexist in the solid substrate, namely, the porous solid substrate contains water and water insoluble substances.

Yellow water is liquid discharged during solid state fermentation, and is a byproduct which is generated by the metabolism of microorganisms, such as organic acid, soluble starch, amino acid, tannin, reducing sugar, flavor precursor and the like which are not utilized by microorganisms in fermented grains in the solid state fermentation process, and is gradually settled and deposited at the bottom of a fermentation tank.

The yellow water contains rich organic acids, alcohols, aldehydes and the like, and especially the organic acids contain the most carboxylic acids such as lactic acid, acetic acid, caproic acid, butyric acid and the like, so that the acid content in the yellow water is 5-10 times of the acid content in common white spirit, and the acidity of the yellow water can reach about 7 degrees; in addition, the yellow water also contains alcohol, sugar, starch, humus, a large number of brewing microorganisms which are domesticated for a long time, precursors which can generate aroma, and the like, so that a proper amount of yellow water is maintained in the fermentation process, and the aroma of the wine can be improved.

The solid state fermentation device 100 in this embodiment mainly includes a tub body 10 and a grate 20 disposed inside the tub body 10.

The inner side of the barrel body 10 is provided with a sealing space 11 (i.e. a fermentation tank) for accommodating the fermented grains P for solid state fermentation reaction. In one embodiment, the sealed space 11 inside the barrel body 10 is tapered from top to bottom to form a collecting space 12 at the bottom, and yellow water S generated during fermentation of the fermented grains P is collected in the collecting space 12 at the bottom of the sealed space 11 through the collecting space 12. In a preferred embodiment, the sealed space 11 inside the tub body 10 tapers from top to bottom to have a U shape, which is not limited in the present utility model. In one embodiment, the tub body 10 includes a tub body 10A and an upper cover 10B disposed on the tub body 10A, and the grate plate 20 is taken out by opening the upper cover 10B to be placed into the fermented grain material P. In a preferred embodiment, a sealing mechanism 10C is disposed between the lower side edge of the upper cover 10B and the upper opening periphery of the tub 10A, thereby improving the airtight effect of the sealed space 11; in an embodiment, the sealing mechanism 10C may be, for example, a sealing strip directly disposed at the lower edge of the upper cover 10B or on the periphery of the upper opening of the tub 10A; in one embodiment, the sealing mechanism 10C may be injection molded directly at the lower edge of the upper cover 10B or the upper opening periphery of the tub 10A, which is not limited in the present utility model; in one embodiment, the sealing mechanism 10C may be, for example, rubber, silicone, or other such elastic material, which is not limited in the present utility model.

The grate plate 20 has a plurality of meshes 21 thereon, and is disposed in the sealed space 11 and under the fermented grain material P to separate the fermented grain material P and yellow water S, and a plurality of stainless steel wires 22 are disposed in the space under the grate plate 20 to generate an interfacial fermentation effect. In one embodiment, the aperture L of the mesh 21 of the grate plate 20 can be, for example, but not limited to, between 1.5mm and 3.0mm (as shown in FIG. 3); in a preferred embodiment, the aperture L of the mesh 21 of the grate plate 20 can be, for example, 2.0mm (as shown in FIG. 3), which is not limited in the present utility model. In one embodiment, the grate 20 is movable, thereby moving up and down in the sealed space 11, further disassembling or assembling, and is used for carrying the fermented grain material P and adjusting the height of the fermented grain material P; the grate plate 20 is used for bearing the fermented grain material P in the sealed space 11 after the fermented grain material P is placed in the sealed space 11. In one embodiment, the grate 20 is made of stainless steel, so as to prevent the aroma and taste of the fermented grains P from being affected by the material of the grate 20.

In order to drain the yellow water S collected at the bottom side, in one embodiment, the tub body 10 includes a yellow water drain pipe 13 connected to the bottom side of the sealed space 11, and an on-off switch 14 disposed on the yellow water drain pipe 13; yellow water S inside the tub body 10 is discharged through the yellow water discharge pipe 13 by turning on the on/off switch 14. In one embodiment, the opening 131 of the yellow water discharging tube 13 in the sealed space 11 is aligned with the low-lying position of the collecting space 12 (e.g. the very center position of the bottom side of the collecting space 12 or other relatively low position).

In one embodiment, the yellow water discharging tube 13 may be an L-shaped bent tube, so as to effectively guide the yellow water S flowing out from the opening 131 to a destination (such as a collecting container or other devices), thereby achieving the effect of recycling the yellow water S. In the fermentation process, a proper amount of yellow water S is maintained for adding the flavor of the finished wine, and the taste of the yellow water S can also be used for judging the fermentation condition of the fermented grains, in one embodiment, the on-off switch 14 can be a check valve or a flow control valve so as to control the discharge amount of the yellow water S and grasp the fermentation condition. Wherein the check valve can be spring type or stop type, and the stop type check valve is preferably used in the utility model. In one embodiment, to achieve the observation of the discharge amount of yellow water S during fermentation, a flowmeter 15 is further provided on the yellow water discharge pipe 13.

In general, the height of the yellow water S immersed in the water is higher than the opening 131 of the yellow water discharge pipe 13 in the sealed space 11, so that the tub body 10 includes an air inlet non-return valve 16 communicated with the sealed space 11 for air inlet, so that the air pressure of the sealed space 11 is balanced when the on-off switch 14 is opened, and the fermented yellow water S is discharged from the yellow water discharge pipe 13. The discharged yellow water S can be returned to the wine for fermentation or mixed with the tail wine in a distillation device in the distillation process and placed in a bottom pot for solid distillation. In one embodiment, the material P is submerged in the intake check valve 16 and is connected to the intake port 161 of the sealed space 11. In yet another embodiment, the non-return valve 16 is positioned at a height above the surface of the yellow water S so that the gas enters the sealed space 11.
