Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation equipment technology, and in particular to a fermentation tank for preparing mulberry fermented wine. Background Technology
[0002] The preparation process of mulberry fermented wine includes preparing qualified raw materials → raw material pretreatment → fermentation → clarification → aging → bottling. In the fermentation process, wide-rimmed, smooth earthenware jars are currently used. White sugar is sprinkled in batches or layers at 10% of the raw material weight, and stirred until fully mixed. Special yeast is added at a ratio of 0.2‰ to 0.5‰ of the raw material weight, sprinkled evenly, stirred, and allowed to stand for 1 hour. The fermentation container is then sealed tightly with food-grade polyethylene film. The container should be placed indoors at 18℃ to 35℃, with adequate space between containers. For the first 7 days after sealing, the container is stirred once daily. Afterward, it is opened and stirred every 7 days, and resealed immediately after each stirring. The fermentation time should be at least 45 days, during which time it needs to be checked frequently. If white bacteria appear on the surface of the fermentation liquid, they should be removed promptly. Fermentation can be stopped when there are no fermentation phenomena on the surface of the fermentation liquid, or when it no longer tastes sweet.
[0003] The current fermentation process requires a lot of manpower, such as multiple aerobic stirring operations. Aerobic stirring requires opening the tank to allow air to enter and using a stirrer for stirring. This results in low efficiency in the preparation of mulberry fermented wine. Furthermore, the possibility of operational errors such as incomplete sealing during the multiple opening and sealing operations is also greater, which will affect the quality of mulberry fermented wine. Utility Model Content
[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a fermentation tank for preparing mulberry fermented wine, which aims to solve the problem of low preparation efficiency and reduced yield caused by the frequent opening and closing of the tank during the fermentation process of mulberry fermented wine.

[0025] The present invention will now be further described with reference to the accompanying drawings.
[0026] This utility model embodiment provides a fermentation tank for preparing mulberry fermented wine, such as... Figure 1As shown, the fermentation tank for preparing mulberry fermented wine includes a support 1, a tank body 2, a motor 3, a blower 4, a rotating shaft 5, stirring blades 6, an exhaust pipe 7, and a guide pipe 8. The support 1 is connected to the lower end 201 of the tank body 2. The upper end 202 of the tank body 2 is provided with a feeding assembly 9, and the lower end of the tank body 2 is provided with a discharging assembly 10. The motor 3 is located at the upper end 202 of the tank body 2. One end of the rotating shaft 5 is connected to the output shaft of the motor 3, and the other end of the rotating shaft 5 is sealed through the upper end 202 of the tank body 2 and located inside the tank body 2. The part of the rotating shaft 5 located inside the tank body 2 is connected to multiple stirring blades 6. The blower 4 is installed at the upper end 202 of the tank body 2. The blower 4 is connected to one end of the exhaust pipe 7, and the other end of the exhaust pipe 7 is sealed through the upper end 202 of the tank body 2 and located inside the tank body 2. The upper end 202 of the tank body 2 is provided with an exhaust port 11, and a guide pipe 8 is installed at the exhaust port 11.
[0027] In practice, the raw materials used to prepare mulberry fermented wine are processed and then fed into tank 2 through discharge assembly 10. Tank 2 is then sealed, meaning that both the exhaust pipe 7 and the guide pipe 8 are closed, preventing air from entering tank 2 through them. As an example, the raw materials for preparing mulberry fermented wine are liquid, and the raw materials carried by one tank 2 do not exceed two-thirds of the maximum volume of tank 2. For example, the raw materials for preparing mulberry fermented wine can be prepared as follows: Mulberries have their stems removed, rotten fruit discarded, washed and drained. The raw materials should be pulped or juiced. The mulberry juice should be pasteurized (62℃~65℃, 30 min; 72℃~76℃, 15 s or 80℃~85℃, 10 s~15 s) or subjected to high-temperature instantaneous sterilization (125℃±1℃, 5 s) to inactivate the main microorganisms.
[0028] Place the tank 2 containing the raw materials in a room with a temperature of 18℃~35℃. If multiple tanks 2 are placed in a room (i.e., multiple fermentation tanks for preparing mulberry fermented wine are used for fermentation), a certain distance should be maintained between each tank 2. The aerobic stirring times for multiple tanks 2 can be staggered to avoid mutual interference. From the date the raw materials are loaded into the tank 2, aerobic stirring should be performed once every seven days until the entire fermentation process is completed.
[0029] The aerobic stirring process is as follows: First, turn on the blower 4, the exhaust pipe 7 and the guide pipe 8. The blower 4 pre-ventilates the tank 2 for a certain period of time, so that the air comes into contact with the liquid in the tank 2. Then, turn on the motor 3. The motor 3 drives the rotating shaft 5 to rotate, and then the stirring blades 6 stir the liquid. After the stirring time is set, turn off the motor 3, the blower 4, the exhaust pipe 7 and the guide pipe 8.
[0030] Therefore, during the entire aerobic stirring process, there is basically no need for human intervention. At the same time, tank 2 does not need to be opened. Only the opening and closing of the air duct 7 and the air guide 8 need to be adjusted. This improves the fermentation efficiency and avoids the impact of operational errors such as not completely sealing the tank on the quality of the mulberry fermented wine, thereby increasing the yield of good products.
[0031] In some embodiments, such as Figure 3 As shown, the exhaust pipe 7 is equipped with a first valve 12 and a first check valve 13. The first valve 12 is used to open and close the exhaust pipe 7, and the first check valve 13 is used to ensure that the gas flow direction in the exhaust pipe 7 is always from outside the tank to inside the tank.
[0032] In some embodiments, such as Figure 2 As shown, a second valve 14 and a second check valve 15 are installed on the air duct 8. The second valve 14 is used to open and close the air duct 8, and the second check valve 15 is used to ensure that the gas flow direction of the air duct 8 is always from inside the tank to outside the tank.
[0033] In some embodiments, such as Figure 4 As shown, the fermentation tank for preparing mulberry fermented wine also includes a controller 16, which is signal connected to the motor 3, the fan 4, the first valve 12, and the second valve 13.
[0034] In this embodiment, a controller 16 is added. This controller 16 can be used to automatically control the motor 3, fan 4, first valve 12, and second valve 13 to start the motor 3, fan 4, first valve 12, and second valve 13 within a set time to complete one cycle of aerobic stirring. For example, during one cycle of aerobic stirring, the controller 16 controls the fan 4, first valve 12, and second valve 13 to start first, and then the motor 3 to start. After the set time is reached, the motor 3, fan 4, first valve 12, and second valve 13 are turned off. The aerobic stirring process throughout the entire fermentation cycle can be implemented automatically without human intervention, greatly improving fermentation efficiency.
[0035] In some embodiments, such as Figure 1 As shown, the bracket 1 includes multiple support legs 101, all of which are connected to the lower end of the tank body 1.
[0036] In some embodiments, such as Figure 1 As shown, the feeding assembly 9 includes a feeding channel 901 and a sealing cover 902. The feeding channel 901 is located at the upper end 202 of the tank body 2, and the sealing cover 902 is movably located in the feeding channel 901 for closing or opening the feeding channel 901.
[0037] In this embodiment, the feeding channel 901 can be in the form of a pipe, which is assembled on the tank 2 through an opening in the tank 2. The feeding channel 901 can be completely closed by the sealing cover 902, so that the feeding component 9 is only opened when feeding and is closed at other times.
[0038] In some embodiments, such as Figure 1 As shown, the discharge assembly 10 includes a discharge port 1001 and a discharge flange 1002. The discharge port 1001 is located at the lower end 201 of the tank body 2, and the discharge flange 1002 is located at the discharge port 1001 for connecting the discharge pipe.
[0039] In this embodiment, the closure of the discharge component 10 can be controlled by a valve installed on the discharge pipe. Generally, the discharge component 10 is only opened after fermentation is completed. The liquid inside the tank 2 is introduced to the next process through the discharge pipe. The next process is clarification. For example, the liquid can be introduced to a clarification tank or reactor through the discharge pipe. The original wine (i.e., the liquid coming out through the discharge component 10) is clarified and impurities are separated by filtering after clarification using a combination of natural clarification and clarification agent (soap clay is expanded with 10 times the amount of pure water for 24 hours, and soap clay is added at a ratio of 1‰ to 5‰ of wine liquid).
[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
