Description

Technical Field

[0001] The present application relates to the technical field of winemaking equipment, and in particular to a sun-drying winemaking equipment. Background Art

[0002] Newly produced wine has a spicy taste and is not mellow. It can only be regarded as a semi-finished product. Generally, it needs to be stored for a certain period of time to allow it to mature naturally. This can reduce the irritation and spiciness of the new wine, making the wine soft and palatable, mellow and fragrant, and the taste is more harmonious. This phenomenon is called aging in the winemaking industry. The aging method is to put the wine in a slightly breathable and leaky container such as pottery, porcelain, or wine sea. The secret of changing the quality of the wine lies in the spontaneous reaction of the wine as the storage period continues to extend, and the aging time needs to be determined according to various conditions such as the type of wine and the temperature. Nowadays, when aging the soy-flavor liquor, it is necessary to carry out two modes in sequence: sun aging and light-proof brewing aging. After searching, the patent document with the authorization announcement number CN208250274U announces a soy-flavor liquor sun aging tank, the tank cover of which is made of transparent material, and a sunshade is designed on the top of the tank cover; a cage is designed in the middle of the aging tank; a pipe is designed above and below the cage to connect with the wine pump outside the tank, the pipe below the cage is a suction pipe, and the pipe above the cage is a lift pipe; an air duct and an air distributor are designed at the bottom of the aging tank, the aging tank is first treated with sunlight, which is conducive to the generation of flavor components, and then aged in the dark to ensure the full reaction and exchange of various components between the aged meat and the wine; the whole process is kept warm to ensure microcirculation, reaction temperature and effective leaching of the aged meat components; the micro-oxidation requirement of the wine is conducive to the production of flavor components and the aging of the wine.

[0003] In actual use, it was found that the above-mentioned related solutions still have at least the following shortcomings: the sunshade needs to be manually disassembled and assembled, which increases the workload, and the operation is not convenient enough; and during the period when the wine and the multiple pieces of aged meat are placed in the aging tank for light aging, since the multiple pieces of aged meat are piled up in the stainless steel cage, the wine will have less contact with the parts where the multiple pieces of aged meat are piled up and fit together, which will cause the wine to be unable to fully and comprehensively contact with the multiple pieces of aged meat, affecting the aging quality of the wine.

[0031] In this embodiment, in order to accurately position the transparent tank cover 2 on the top of the aging tank 1 , a positioning ring 14 is fixedly installed on the bottom of the transparent tank cover 2 , and the top of the aging tank 1 extends into the positioning ring 14 .

[0032] In the present embodiment, in order to improve the sealing effect when the transparent tank cover 2 is installed on the top of the aging tank 1, a sealing ring 15 is fixedly installed on the inner ring wall of the positioning ring 14, and the outer ring of the sealing ring 15 is in sliding and sealing contact with the outer wall of the aging tank 1. It should be supplemented that by utilizing the sliding and sealing contact between the sealing ring 15 and the aging tank 1, and utilizing the deadweight of the transparent tank cover 2 and the weight of the rotating motor 12, the hanger 13 and the aged meat hooked on the hanger 13 arranged on the transparent tank cover 2, it is possible to ensure that the transparent tank cover 2 is stably installed on the top of the aging tank 1, and the transparent tank cover 2 will not shift autonomously during the aging of the wine.

[0033] In this embodiment, in order to facilitate the lifting or removal of the transparent tank cover 2 , two lifting rings 16 are fixedly installed on the top of the transparent tank cover 2 , and the two lifting rings 16 are symmetrically distributed on both sides of the rotating motor 12 .

[0034] In the present embodiment, during the aging of the wine, in order to facilitate sampling of the wine inside the aging tank 1, a plurality of sampling tubes 17 are fixedly connected on the front outer wall of the aging tank 1, and sampling valves 18 are fixedly installed on the plurality of sampling tubes 17, and the plurality of sampling tubes 17 are arranged vertically. It should be noted that the number of the sampling tubes 17 is not less than two, so that the wine at different depths inside the aging tank 1 can be sampled.

[0035] In this embodiment, Figure 1 and Figure 2 As shown, the two shading plates 3 are both located above the transparent tank cover 2. At this time, the two shading plates 3 are used to block sunlight from shining on the transparent tank cover 2, that is, the wine is in a state of being brewed and aged in a dark environment. Figure 5 As shown, the two shading plates 3 are respectively located below the two sides of the transparent tank cover 2. At this time, the two shading plates 3 will not block the sunlight from shining on the transparent tank cover 2, that is, the state when the wine is used for sun aging.

[0036] In the present embodiment, it should be noted that the aging tank 1 is also equipped with accessories such as a wine pump, a suction pipe, a lift pipe, an air duct, an air distributor, and a temperature probe (not shown in this article). The assembly connection relationship and the principle of use thereof have been publicly described in the patent document of a soy-flavored liquor sun-drying aging tank disclosed in the authorization announcement number CN208250274U, and therefore will not be further elaborated in this article.

[0037] Through the above-mentioned structure, the light aging equipment provided by the present application is convenient for automatically adjusting the position of the shading plate 3 when in use, which can effectively replace the existing method of manually disassembling and assembling the shading plate 3, reducing the amount of manual labor, and can hang multiple pieces of aged meat evenly in the internal space of the aging tank 1, and can control the multiple pieces of aged meat on the hanging rack 13 to rotate, so that the wine in the aging tank 1 can be more fully and comprehensively in contact with the multiple pieces of aged meat, thereby improving the aging quality of the wine. During specific operation, by controlling the left-side drive motor 11 to rotate forward and controlling the right-side drive motor 11 to reverse (from the main view), the left-side drive motor 11 drives the left-side rotating shaft 8, the shaft sleeve 9, the connecting rod 10 and the shading plate 3 to rotate reversely. The driving motor 11 on the right side drives the rotating shaft 8, the shaft sleeve 9, the connecting rod 10 and the shading plate 3 on the right side to rotate clockwise, so that the two shading plates 3 can be gradually adjusted to the appropriate positions on both sides of the aging tank 1. At this time, the two shading plates 3 will not block the transparent tank cover 2. Then, the transparent tank cover 2 and the hanging rack 13 can be hung out of the aging tank 1 by using the lifting equipment, and then the cut pieces of aged meat are respectively inserted and hung on the corresponding hooks 133, so that multiple pieces of aged meat are evenly displayed and arranged, and then a suitable amount of wine is poured into the aging tank 1, and then the transparent tank cover 2 is adjusted back to the top of the aging tank 1 by using the lifting double equipment. At this time, the multiple pieces of aged meat hung on the hanging rack 13 are immersed in the wine and can be aged.

[0038] When the wine needs to be aged under sunlight, the two shading plates 3 are gradually adjusted to appropriate positions on both sides of the aging tank 1 according to the above operation steps. The two shading plates 3 will not block the transparent tank cover 2, and sunlight can be irradiated into the wine through the transparent tank cover 2, that is, the wine is aged under sunlight. During the aging under sunlight, the rotating motor 12 is regularly turned on to run for a period of time, and the rotating motor 12 drives the rack 13 and the multiple pieces of aged meat hung thereon to rotate, so that the wine in the aging tank 1 can be more fully and comprehensively in contact with the multiple pieces of aged meat, thereby improving the quality of the wine under sunlight aging.

[0039] When it is necessary to brew and age the wine in a dark place, by controlling the left drive motor 11 to reverse and the right drive motor 11 to rotate forward (from the main viewing angle), the left drive motor 11 drives the left rotating shaft 8, shaft sleeve 9, connecting rod 10 and shading plate 3 to rotate clockwise, and the right drive motor 11 drives the right rotating shaft 8, shaft sleeve 9, connecting rod 10 and shading plate 3 to rotate counterclockwise, so that the two shading plates 3 can be gradually adjusted to above the transparent tank cover 2 until the two shading plates 3 collide with each other, and the two drive motors 11 are stopped. At this time, the two shading plates 3 can completely block the transparent tank cover 2, and sunlight will not shine on the transparent tank cover 2, so that the wine can be brewed and aged in a dark place. During the dark-proof brewing and aging period, the rotating motor 12 can also be regularly turned on to run for a period of time, so that the wine in the aging tank 1 can be more fully and comprehensively in contact with multiple pieces of aged meat, thereby improving the quality of the wine in the dark-proof brewing and aging.
