Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stirring structure technology, specifically relating to a mixing device for fermenting aged vinegar. Background Technology
[0002] Currently, in the process of brewing aged vinegar, in order to ensure that the materials are fully fermented in the early or middle stages, it is often necessary to mix them. Most fermentation mixing devices currently use a circular rotation mixing method. However, this method can only meet the fermentation needs in the early stage. In the middle stage of fermentation, due to the precipitation of liquid and the reduction of the mass of solid materials, the liquid and solid materials will separate into layers. This phenomenon is more concentrated in solid fermentation. When this phenomenon occurs, on the one hand, it is easy to reduce the moisture content of the upper solid material, resulting in insufficient fermentation reaction of microorganisms. On the other hand, it is also easy to have insufficient mixing when rinsing vinegar or in the initial mixing. Utility Model Content
[0003] The purpose of this invention is to provide a vinegar fermentation mixing device to solve the problems mentioned in the background art.
[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0005] A fermentation and mixing device for aged vinegar includes a fermentation tank, wherein the fermentation tank is provided with a feed inlet and a discharge outlet at its upper and lower ends, and the fermentation tank is provided with a fermentation mechanism;
[0006] The fermentation mechanism includes a mixing assembly and a pipe assembly. The mixing assembly is located at the upper end of the fermentation tank, and the pipe assembly is located on the side of the fermentation tank and communicates with the inside of the fermentation tank.
[0007] The mixing assembly includes a hydraulic cylinder, an extension rod, and a mixing rake. The hydraulic cylinder is fixedly mounted on the upper end of the fermentation tank. The output shaft of the hydraulic cylinder slides and extends into the fermentation tank and is connected to the extension rod. The mixing rake is connected to the extension rod and matches the space inside the fermentation tank.
[0008] The mixing rake consists of several rake rings and rake rods. The diameters of the rake rings decrease from large to small and are concentrically distributed with the axis of the extension rod. The rake rods are evenly distributed with the axis of the extension rod as the center and connect the rake rings.
[0009] The rake rod and rake ring are plate-shaped structures.
[0010] The rake rod and rake ring are round rod structures.
[0011] The pipe assembly includes a water pump, a lower pipe, a return pipe, a bypass pipe, and a spray pipe. The water pump is fixedly installed on the side of the fermentation tank. The spray pipe and the lower pipe are respectively located on the upper and lower sides inside the fermentation tank. The return pipe is located on the side of the fermentation tank and is connected to the inlet and outlet of the water pump. The outlet and inlet of the return pipe are respectively connected to the spray pipe and the lower pipe. The bypass pipe is connected to the return pipe and is located on the inlet section side of the return pipe.
[0012] The bypass pipe is connected to the external oxygen supply mechanism and is equipped with a one-way air intake valve. Several outlets are evenly opened on the lower side of the lower pipe, and several nozzles facing the lower side of the fermentation tank are evenly provided on the water spray pipe.

[0019] Fermentation tank 1, feed inlet 11, discharge outlet 12, hydraulic cylinder 2, extension rod 21, rake ring 22, rake rod 23, water pump 3, lower pipe 31, return water pipe 32, bypass pipe 33, water spraying pipe 34, one-way air inlet valve 35, discharge outlet 36. Detailed Implementation
[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] like Figure 1-3 As shown, a fermentation mixing device for aged vinegar includes a fermentation tank 1, with an inlet 11 and a outlet 12 at the top and bottom of the fermentation tank 1, respectively, and a fermentation mechanism is provided in the fermentation tank 1.
[0022] The fermentation mechanism includes a mixing assembly and a pipe assembly. The mixing assembly is located at the upper end of the fermentation tank 1, and the pipe assembly is located on the side of the fermentation tank 1 and communicates with the inside of the fermentation tank 1.
[0023] The mixing assembly includes a hydraulic cylinder 2, an extension rod 21, and a mixing rake. The hydraulic cylinder 2 is fixedly installed at the upper end of the fermentation tank 1. The output shaft of the hydraulic cylinder 2 slides and extends into the fermentation tank 1 and is connected to the extension rod 21. The mixing rake is connected to the extension rod 21 and matches the space inside the fermentation tank 1.
[0024] During the fermentation process of aged vinegar, the material is fermented in fermentation tank 1. During fermentation, the material will form a preliminary stratification, that is, some solid material becomes lighter and floats to the top, while the liquid remains in the lower part of fermentation tank 1. To ensure that the upper solid material can ferment fully, the material needs to be stirred during fermentation. When stirring, hydraulic cylinder 2 is activated to make the output shaft of hydraulic cylinder 2 extend and retract cyclically. When the output shaft of hydraulic cylinder 2 extends and retracts, it will drive the extension rod 21 to move in fermentation tank 1, and then the material in fermentation tank 1 will be pushed and stirred up and down by the mixing rake. Some of the material in the upper part of fermentation tank 1 will be pushed into the liquid in the lower part of fermentation tank 1 to form immersion and mixing, so as to improve the fermentation effect.
[0025] In the early stages of fermentation, the materials and microorganisms can be effectively mixed by pushing and turning the mixture with a mixing rake, which further meets the needs of aged vinegar brewing.
[0026] The pipe assembly is used to pump out the liquid in fermenter 1, drawing it out from the lower side of fermenter 1 and discharging it from the upper side of fermenter 1, so as to further improve the uniformity of the material in fermenter 1.
[0027] The mixing rake consists of several rake rings 22 and rake rods 23. The diameters of the rake rings 22 decrease from large to small and are concentrically distributed with the axis of the extension rod 21. The rake rods 23 are evenly distributed with the axis of the extension rod 21 as the center and connect the rake rings 22.
[0028] The distribution of the rake ring 22 and the rake rod 23 makes the entire mixing rake form a spider web, which can provide a better mixing effect when the mixing rake is turning over.
[0029] The rake handle 23 and the rake ring 22 are plate-shaped structures.
[0030] The planar plate-like structure provides a larger contact and contact area for mixing materials, which can improve the mixing effect.
[0031] The rake rod 23 and the rake ring 22 are round rod structures.
[0032] The smooth structure of the round rod can reduce the amount of material adhering to it while providing material pushing and mixing, and reduce the amount of material leaving the fermentation tank 1 when the mixing rake resets, while also making it easier to clean.
[0033] The pipe assembly includes a water pump 3, a downpipe 31, a return pipe 32, a bypass pipe 33, and a sprinkling pipe 34. The water pump 3 is fixedly installed on the side of the fermentation tank 1. The sprinkling pipe 34 and the downpipe 31 are respectively installed on the upper and lower sides of the fermentation tank 1. The return pipe 32 is located on the side of the fermentation tank 1 and is connected to the inlet and outlet of the water pump 3. The outlet and inlet of the return pipe 32 are respectively connected to the sprinkling pipe 34 and the downpipe 31. The bypass pipe 33 is connected to the return pipe 32 and is located on the inlet section side of the return pipe 32.
[0034] The bypass pipe 33 is connected to the external oxygen supply mechanism and is equipped with a one-way air inlet valve 35. The lower pipe 31 has several outlets 36 evenly distributed on its lower side, and the water spray pipe 34 is evenly equipped with several nozzles facing the lower side of the fermenter 1.
[0035] During the fermentation process, the water pump 3 is used to provide the power to pump the liquid, and the return water pipe 32 is used to connect the inlet and outlet of the water pump 3, thereby connecting the lower pipe 31, the water pump 3 and the water spraying pipe 34 into one unit. The lower pipe 31 is connected to the inlet end of the water pump 3 through the return water pipe 32, while the water spraying pipe 34 is connected to the outlet end of the water pump 3 through the return water pipe 32.
[0036] During the mixing process or when not mixing, the water pump 3 starts to generate liquid suction force. Since more liquid exists in the lower part of the fermentation tank 1 during the fermentation process, the water pump 3 will draw out this part of the liquid and discharge it through the pipeline from the water spray pipe 34, so that the liquid in the lower part is discharged from the upper part of the fermentation tank 1. This can keep the fermented material in the upper part of the fermentation tank 1 moist in real time, ensuring the fermentation effect. Moreover, this spraying method is more suitable for use in fermentation tanks 1 with larger storage capacity, which can reduce the problems of long torque, high resistance and displacement of fermented material in conventional rotary stirring structures.
[0037] At other times, when the water pump 3 is not running for liquid replacement spraying, an external air supply mechanism, such as an air compressor, can input filtered air through the bypass pipe 33. The one-way air inlet valve 35 is set to only allow air to enter the bypass pipe 33 from the outside, thus preventing liquid from entering the bypass pipe 33 when the water pump 3 starts. Furthermore, an electric or manual valve can be added to the liquid inlet of the water pump 3 to close the pipeline from the return water pipe 32 to the spray pipe 34, so that air can only be discharged through the return water pipe 32 and the lower pipe 31. At this time, the air is transported from bottom to top in the fermentation tank 1 and finally discharged through the feed inlet 11. Of course, it can also be discharged through the pressure valve set in the fermentation tank 1. This method can further assist stirring on the one hand, and meet the oxygen requirements of fermentation on the other hand, so that oxygen can be injected into the fermentation material more evenly.
[0038] It is worth noting that, regarding the filtration issue at the outlet 36, since the injected oxygen has a certain pressure force, the potential clogging problem caused by fermentation material at the outlet 36 will not exist. However, considering that some material may enter the water pump 3 and the spray pipe 34 through the return water pipe 32, causing the nozzles on the water pump 3 and the spray pipe 34 to become clogged or aged, a corresponding filtration structure such as a filter screen can still be installed at the outlet 36 of the lower pipe 31. However, this application does not impose any technical limitations and is merely an option that can be chosen by those skilled in the art.
[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
