Description

Technical Field

[0001] The utility model relates to the technical field of liquor processing, in particular to a liquor aroma fermentation device. Background Art

[0002] Fermentation is the key to aroma, while distillation is the key to aroma. The aroma of liquor is closely related to fermentation. Fermentation time, fermentation container, and fermentation method will all affect the formation of liquor aroma. For example, the unique flavor of high-quality Maotai-flavor liquor is inseparable from its unique yin-yang fermentation. Yin fermentation is closed fermentation, or anaerobic fermentation, which is also the only fermentation method for other types of liquor. Yang fermentation is high-temperature stacking fermentation, also known as open fermentation.

[0003] In the prior art, in the positive fermentation process of liquor, it is necessary to pile the materials in a cone shape on the ground, and through direct contact between the materials and the air, capture the effective bacteria in the air for fermentation, and in order to improve the fermentation efficiency, rice husks are sometimes added to the materials to increase their fluffiness, increase the contact area between the materials and the air, and accelerate the positive fermentation efficiency. After searching, the existing patent with publication number CN214881366U discloses an aerobic stacking fermentation oxygenation device for sauce-flavor liquor, which is placed in the pile through a truncated cone frame structure and pumps oxygen to increase the positive fermentation reaction rate. Furthermore, the patent with publication number CN218579915U discloses a stacking device for improving the aroma production effect of sauce-flavor liquor on the basis of the above patents, and a protective structure is set to prevent the material from entering the air supply pipe through the air supply hole to cause blockage.

[0004] However, both of the above methods require that the device be buried inside the material before the material is stacked, or the material be stacked directly on top of the device. The device has a complex frame structure, and the production of liquor requires several cycles of yin and yang fermentation, which results in the need to recover the stacked materials multiple times. The structural complexity of the device makes it inconvenient to recycle the materials. Therefore, the present application provides a liquor aroma fermentation device to meet the needs.

DETAILED DESCRIPTION

[0028] The following is a detailed description of a liquor aroma fermentation device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0029] like Figure 1 - Figure 6 As shown, the embodiment of the utility model provides a white wine aroma fermentation device, including a base 3, which is a cylindrical structure, preferably buried underground, and the bottom of the base 3 is a closed structure; a liner 7, rotatably connected to the inner wall of the base 3, and the two are preferably connected by a bearing; a lifting seat 6, including a cylinder 61 and a mounting seat 62 fixed to the bottom of the cylinder 61, the mounting seat 62 is threadedly connected to the liner 7, the cylinder 61 and the mounting seat 62 are both open-ended through grooves at both ends and are connected to each other, and the cylinder 61 is close to the top position A plurality of through holes 64 are provided, and the radial cross-section of the cylinder 61 is non-circular; the air pipe 4 is fixed on the side wall of the base 3 and communicated with the inside of the base 3 for pumping air into the base 3; the sealing plate 5 is sealed and connected with the top opening of the lifting seat 6; the bottom plate 1 is fixedly connected to the top of the base 3 and is slidably connected with the cylinder 61; a baffle 2 is provided at the peripheral position of the top of the bottom plate 1 for facilitating the stacking of materials. When in use, the top of the bottom plate 1 is flush with the ground height for facilitating the stacking of materials; the baffle plate 11 is an inverted trumpet-shaped structure (refer to Figure 6 ) and is fixedly connected to the inside of the cylinder 61 to collect the material that penetrates into the cylinder through the through hole 64. A channel connecting the upper and lower ends of the baffle plate 11 is provided in the middle position to ensure that the gas can flow.

[0030] A base 3 is arranged under the bottom plate 1 where materials are piled, and a lifting seat 6 which can be lifted linearly is arranged inside the base 3, and an external air pump is connected via 4. When materials are piled, the height of the lifting seat 6 is raised, and air is pumped from the inside of the pile to the outside through the through hole 64, thereby increasing the contact area between the pile and the external air, increasing the positive fermentation rate, and further increasing the production efficiency of liquor. At the same time, by arranging a liftable structure, when materials need to be recycled, the lifting mechanism sinks to ensure that the bottom plate 1 is flat as a whole, which is convenient for material recycling. Furthermore, a material baffle plate 11 is provided to collect materials that have penetrated into the cylinder 61, so as to prevent them from falling and accumulating directly to cause blockage, thereby affecting the normal operation of the device.

[0031] like Figure 5 As shown, the inner wall of the liner 7 is provided with a retaining ring 73, an internal thread 71 and an annular tooth 72 in sequence from top to bottom, and the retaining ring 73 protrudes from the internal thread 71 and the annular tooth 72, that is, the inner diameter of the retaining ring 73 is smaller than the inner diameters of the internal thread 71 and the annular tooth 72, and the inner diameter of the annular tooth 72 is slightly larger than the inner diameter of the internal thread 71, so that the mounting seat 62 is inserted from the bottom of the liner 7 and enters the internal thread 71 area.

[0032] like Figure 4 As shown, an external thread 621 is provided on the outer wall of the mounting seat 62, and the external thread 621 is threadedly connected with the internal thread 71. A support rod 66 is provided on the inner side of the mounting seat 62. Preferably, two support rods 66 are provided and distributed in a cross shape to improve the structural support of the lifting seat 6 in the mounting seat 61 area and improve its structural strength.

[0033] like Figure 4 As shown, the vertical projection of the cylinder 61 is completely within the area of ​​the mounting seat 62, and a positioning block 63 is provided at the turning point between the outer wall of the cylinder 61 and the mounting seat 62. There are a plurality of positioning blocks 63, and the top of each positioning block 63 is on the same horizontal plane, and the positioning block 63 is set to be in close contact with the bottom of the retaining ring 73 when the cylinder 61 rises to a certain height.

[0034] In actual operation, as the lifting seat 6 continues to rise, it stops rising when the positioning block 63 contacts the bottom of the retaining ring 73. At this time, the top of the lifting seat 6 protrudes from the top of the bottom plate 1, and the through hole 64 is located above the top plane of the bottom plate 1.

[0035] like Figure 3 As shown, it also includes a motor 9, which is fixedly connected to the lower side of the inner wall of the base 3, and a gear 10 is fixedly connected to the output end of the motor 9, and the gear 10 is meshed with the annular gear 72.

[0036] By setting up the motor 9 to drive the gear 10, and then cooperating with the meshing connection with the annular tooth 72, the lining 7 is driven to rotate as a whole inside the base 3. At this time, due to the relative stillness of the bottom plate 1 and the non-circular radial cross-section of the cylinder 61, under the limiting action of the slide groove opened on the bottom plate 1, the lifting seat 6 as a whole does not rotate synchronously with the lining 7. At this time, through the cooperation of the internal thread 71 and the external thread 621, the lifting seat 6 makes a linear motion in the up and down directions as the lining 7 rotates.

[0037] like Figure 3 and Figure 4 As shown, a mounting groove 65 is provided on the top of the cylinder 61, and the sealing plate 5 is fixedly connected to the mounting groove 65 by bolts, and a sealing gasket is provided at the connection.

[0038] By providing an opening at the top of the cylinder 61 and sealingly connecting the sealing plate 5, the sealing plate 5 is sealed at the top of the cylinder 61 during normal operation. When performing regular cleaning work, the sealing plate 5 is opened and the cylinder 61 is penetrated into its interior from above to take out the materials collected on the baffle plate 11.

[0039] like Figure 4 As shown, a plurality of through holes 64 are equidistantly distributed on the side wall of the cylinder 61 and are all at the same height.

[0040] By providing a plurality of through holes 64 in a dispersed distribution, the radiation area of ​​the gas pump is increased, and the fermentation efficiency is further improved.

[0041] like Figure 3 As shown, a sealing ring 8 is provided at the sliding connection position between the cylinder 61 and the bottom plate 1 .

[0042] The sealing ring 8 is provided to seal the sliding fit between the cylinder 61 and the bottom plate 1 to prevent the material from penetrating into the gap between the lifting seat 6 and the liner 7 from the connection between the two, thereby affecting the threaded connection between the internal thread 71 and the external thread 621, and the meshing connection between the gear 10 and the annular gear 72.

[0043] The technical solution provided by the utility model is that in actual operation, the base 3 is deeply buried in the ground to ensure that the bottom plate 1 is flush with the ground height, which is convenient for material stacking and transfer. When in use, the material that has undergone a round of fermentation is stacked in a cone shape on the bottom plate 1, and the external air pump connected to the air pipe 4 is started to pump air into the base 3. At this time, the internal air pressure of 3 is greater than the external natural air pressure, and the motor 9 is started to drive the gear 10 to rotate, and then cooperate with the annular gear 72 to make the liner 7 rotate as a whole inside the base 3. At this time, due to the non-circular radial cross-section of the cylinder 61, under the limiting effect of the slide groove opened on the bottom plate 1, the lifting seat 6 as a whole does not rotate synchronously with the liner 7. At this time, through the cooperation of the internal thread 71 and the external thread 621, the lifting seat 6 rises linearly with the rotation of the liner 7. Until the positioning block 63 contacts the bottom of the retaining ring 73, the motor 9 stops running. At this time, the top of the cylinder 61 protrudes from the bottom plate and penetrates into the interior of the accumulated material, and the through hole 64 is connected to the top space of the bottom plate 1 (i.e., the internal area of ​​the material). Due to the high-pressure environment inside the base 3, the air flow flows from the inside of the material to the outside, and due to the positive pressure environment, the material infiltrating into the base 3 through the through hole 64 is reduced. After the positive fermentation is completed, the motor 9 reverses, drives the lifting seat 6 to reset and then turns off the air pump. At this time, the top of the lifting seat 6 is flush with the bottom plate 3, which is convenient for recovering the accumulated material. Since a small amount of material inevitably infiltrates into the cylinder 61 through the through hole 64 when the lifting seat 6 is reset, the material is blocked and collected by the material blocking plate 11, and can be taken out by opening the sealing plate 5 at the top of the cylinder 61.

[0044] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
