Description

Technical Field

[0001] The invention relates to the technical field of wine brewing equipment, in particular to an oxygen dissolver device. Background Art

[0002] Maotai-flavor liquor is well-known both at home and abroad for its complex brewing process and rich aroma components. The high temperature environment in the brewing process of Maotai-flavor liquor is significantly different from that of other flavor liquors. High-temperature stacking is one of the unique production processes of Maotai-flavor liquor. This process can capture microorganisms in the surrounding environment and is called "secondary koji making" in the industry. The number of yeasts in the high-temperature Daqu used in Maotai-flavor liquor is very small, and the large-scale reproduction and enrichment of yeasts is achieved during the stacking process. If stacking is not carried out and the wine is directly fermented in the cellar, no wine will be produced or the quality of the wine produced will be poor. At the same time, during the stacking fermentation process, a large amount of aroma and precursor substances are produced under the joint action of microorganisms and enzymes, which plays an important role in improving the quality of Maotai-flavor liquor.

[0003] The production cycle of Maotai liquor is one year, and the first and second rounds of production are usually in winter when the temperature is low. During the pile fermentation, the oxygen content in the center of the pile is low, and the microorganisms reproduce and metabolize slowly, which can easily cause the saccharification pile to heat up slowly or even cause a cold heart phenomenon. At the same time, the saccharification pile does not heat up for a long time, the mash produces a lot of acid, the fermentation is not thorough, and the aroma of the pile is poor, which in turn affects the output and quality of the liquor.

[0037] Combine the following Figures 1 to 4 The oxygen dissolving device of the present invention is described, and the oxygen dissolving device can be applied to the first round and second round stacking fermentation process of the sauce-flavor workshop. Figures 1 to 3 As shown, the oxygen dissolver device 100 includes a main body 1 and a movable cover plate 2 .

[0038] like Figure 2 and Figure 3 As shown, the main body 1 is arranged in a cylindrical shape, and the peripheral side wall of the main body 1 is provided with air holes through it, and the top of the main body 1 is provided with an opening 11. The main body 1 is usually arranged in a frustum shape that is small at the top and large at the bottom, for example, the main body 1 is arranged in a truncated cone shape. In addition, the peripheral side wall of the main body 1 is provided with a plurality of air holes along the vertical direction and the circumference of the main body 1, for example, the peripheral side wall of the main body 1 is evenly provided with a plurality of air holes along the vertical direction and the circumference of the main body 1.

[0039] like Figure 2 and Figure 3 As shown, the movable cover plate 2 is openably disposed at the opening 11 of the main body 1, and is used to open and close the opening 11 through the movable cover plate 2. The movable cover plate 2 is usually adapted to the shape of the opening 11 of the main body 1, for example, the opening 11 is a circular opening, and the movable cover plate 2 is a circular cover plate.

[0040] Specifically, if Figure 1 As shown, before the saccharification pile begins to accumulate, the oxygen dissolving device 100 is placed at the center of the saccharification pile, and the fermentation materials are accumulated manually or by machine. During the accumulation process, the top of the oxygen dissolving device 100 is ensured to be higher than the highest point of the fermentation pile 200, so that the materials inside the accumulated materials are completely in contact with the air through the oxygen dissolving device 100. During the fermentation process, the movable cover 2 of the oxygen dissolving device 100 is opened and closed according to the real-time temperature and related data, so as to further improve the fermentation quality of the saccharification pile.

[0041] The oxygen dissolving device 100 provided by the present invention can be applied to the first and second rounds of pile fermentation processes in a sauce-flavor workshop. By extending the contact time between the pile core and the air, the fermentation temperature of the pile core is increased, the types and quantities of microorganisms are increased, and the saccharification pile fermentation quality is improved.

[0042] The opening 11 is opened and closed by the movable cover 2, specifically, as Figure 2 and Figure 3As shown, in this embodiment, the movable cover 2 is detachably connected to the main body 1 through the connecting member 3; when the movable cover 2 is connected to the main body 1 through the connecting member 3 and the movable cover 2 is in the first position, the peripheral side of the movable cover 2 abuts against the edge of the opening 11, and the opening 11 is in a closed state; when the movable cover 2 is connected to the main body 1 through the connecting member 3 and the movable cover 2 is in the second position, one end of the movable cover 2 abuts against the edge of the opening 11, the movable cover 2 is inclined relative to the opening 11, and the opening 11 is in an open state. The movable cover 2 can be flipped relative to the main body 1, and the opening degree of the opening 11 can be adjusted by flipping the movable cover 2. When the movable cover 2 is separated from the main body 1, the opening 11 is completely open to the outside.

[0043] Further, if Figure 2 and Figure 3 As shown, in this embodiment, the connecting member 3 includes a hanging rod 31 and a hanging ring 32, the hanging rod 31 is horizontally arranged in the top of the main body 1, the hanging ring 32 is vertically arranged on the hanging rod 31, and the top of the hanging ring 32 extends upward from the main body 1; the movable cover plate 2 is provided with a waist-shaped hole 21 through it; when the movable cover plate 2 is connected to the main body 1 through the connecting member 3, the top of the hanging ring 32 passes through the movable cover plate 2 from the waist-shaped hole 21.

The air holes are formed by the mesh plate.

[0046] Specifically, Figure 3 and Figure 4As shown, in this embodiment, the bracket 12 includes an upper annular connecting plate 121, a lower annular connecting plate 122 and a reinforcing rod 123; the upper annular connecting plate 121 and the lower annular connecting plate 122 are spaced apart from each other, the upper annular connecting plate 121 is connected to the top inner side of the peripheral plate 13, and the lower annular connecting plate 122 is connected to the bottom inner side of the peripheral plate 13; the reinforcing rod 123 is arranged in the up-down direction, the reinforcing rod 123 is connected to the inner side of the peripheral plate 13, and a plurality of reinforcing rods 123 are arranged at intervals along the circumference of the peripheral plate 13. In this way, not only is the structure of the bracket 12 relatively simple, but the overall strength of the main body 1 is also relatively good.

[0047] Further, if Figure 3 and Figure 4 As shown, in this embodiment, the bracket 12 further includes a middle annular connecting plate 124, which is located between the upper annular connecting plate 121 and the lower annular connecting plate 122, and the middle annular connecting plate 124 is connected to the inner side of the outer plate 13. The overall strength of the main body 1 can be further improved by providing the middle annular connecting plate 124.

[0048] like Figure 3 and Figure 4 As shown, in this embodiment, each reinforcing rod 123 is sequentially connected to the upper annular connecting plate 121, the middle annular connecting plate 124 and the lower annular connecting plate 122, and the upper annular connecting plate 121, the middle annular connecting plate 124 and the lower annular connecting plate 122 are all provided with notches corresponding to the reinforcing rod 123.
