Description

Technical Field

[0001] This utility model relates to the technical field of rice wine production equipment, specifically a rice wine fermentation mash cooling device. Background Technology

[0002] During the saccharification and fermentation process, the fermenting mash needs to be kept at 30-32°C initially. After fermentation for a period of time, it is then appropriately cooled to reach the optimal fermentation temperature. Traditionally, the cooling method for fermenting mash involves using a chiller to cool the water, which is then injected into the inner wall of the coil installed inside the fermentation tank or into the jacket space outside the fermentation tank to lower the temperature of the fermenting mash.

[0003] However, this cooling method generally only cools the fermenting mash from the side wall of the fermentation tank towards the center, resulting in uneven cooling of the entire fermenting mash. Especially when the fermenting mash has a high concentration in the early stage, i.e., when it is in a solid-liquid mixed state, if the fermenting mash in the middle cannot be cooled in time, the temperature of the fermentation tank will be too high or the stirring time will be too long, causing the mash temperature to remain at a high temperature (above 35°C) for a long time. The yeast will age prematurely due to the heat, and the saccharification in the mash will intensify, resulting in excessive sugar accumulation. Once the acidifying bacteria take advantage of this environment, it will easily become sour, making the mash taste sweet and sour. The yeast will become smaller, increasing the number of yeasts and the number of miscellaneous and heterotrophic yeasts. Therefore, a cooling device for rice wine fermentation mash is proposed to solve the defects of traditional cooling devices. Utility Model Content

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0017] Please see Figure 1-6 This utility model provides an embodiment of a rice wine fermentation mash cooling device, comprising a tank body 1, wherein a cooling component 3 is provided on the tank body 1; the cooling component 3 includes a tank cover 30; a rotating component 35 is provided on one side of the tank cover 30, and a circulation pipe 31 is provided on the other side of the tank cover 30; the rotating component 35 includes a rotating seat 38 and a pressure cap 39 covering the rotating seat 38, wherein after the pressure cap 39 is placed on the rotating seat 38, the rotating seat 38 rotates outside the pressure cap 39; therefore, when the rotating seat 38 rotates, the cooling input pipe installed on the pressure cap 39 will not rotate with the rotating seat 38.

[0018] A first connecting pipe 312 is fixedly connected to the center of the rotating seat 38, and one end of the first connecting pipe 312 is connected to the circulation pipe 31, specifically through a nut 32. The other end of the first connecting pipe 312 passes through the pressure cap 39 and protrudes above it, making it easy for the user to hold the first connecting pipe 312 at the top of the pressure cap 39 and rotate the rotating seat 38 on the can lid 30. The portion of the first connecting pipe 312 above the pressure cap 39 also facilitates connection to the drive unit 36. Specifically, the driven wheel 319 is fixed to the first connecting pipe 312 and connected to the output wheel of the reduction motor 318 via a belt, allowing the rotating seat 38 to rotate automatically, reducing manual intervention. In addition, the pressure plate 317 is used to press on the pressure cover 39 to prevent the pressure cover 39 from rotating and to prevent the coolant inside the rotating seat 38 from flowing out. The inner wall of the driven wheel 319 and the outer wall of the second connecting pipe 312 are both provided with keyways. The driven wheel 319 drives the first connecting pipe 312 to rotate by inserting a key into the keyway.

[0019] Furthermore, the rotating seat 38 is also provided with a second connecting pipe 311. One end of the first connecting pipe 311 is connected to the circulation pipe 31 through a nut 32, and the other end is connected to the interior of the rotating seat 38. At this time, after the coolant enters the rotating seat 38, it is introduced into the circulation pipe 31 through the second connecting pipe 311 and then flows out through the first connecting pipe 312. Thus, the coolant can circulate to improve the cooling effect of the equipment.

[0020] In summary, the first connecting pipe 312 causes the rotating seat 38 to rotate on the tank cover 30, thus allowing the circulation pipe 31 to rotate inside the tank 1 to agitate the liquid inside. Simultaneously, coolant enters through the second connecting pipe 311 and flows out through the first connecting pipe 312, thereby cooling the liquid inside the tank 1. In particular, utilizing the structural advantages of the circulation pipe 31—that it can reach different positions in the liquid both vertically and horizontally—it can simultaneously cool the liquid at various locations when it rotates. Therefore, this device not only agitates the liquid but also solves the problem of existing equipment being unable to cool the center of the liquid inside the tank.

[0021] Furthermore, since the end of the first connecting pipe 312 furthest from the circulation pipe 31 is connected to the rotary joint via an adapter 37, the rotation of the rotary joint can prevent the coolant return pipe from rotating with the first connecting pipe 312, thus avoiding the problem of external pipelines becoming tangled or broken due to tangling during cooling and stirring. Additionally, the pressure cap 39 is also equipped with a connector 316, through which coolant is introduced into the rotating seat 38, thus facilitating the installation of the coolant delivery pipe onto the connector 316. The adapter 37 and connector 316 have identical structures, both being threadedly connected to corresponding connection points via threads on their outer walls.

[0022] To ensure that the cap 39 can be reliably pressed onto the rotating seat 38, the can cover 30 is also provided with a bracket 33; and a screw 34 is provided on the bracket 33, and the screw 34 causes the pressure plate 317 to move downward along the inner wall of the bracket 33. Therefore, the tightening of the screw 34 causes the pressure plate 317 to press onto the cap 39, ensuring the seal of the cap 39 on the rotating seat 38. At the same time, the position of the pressure plate 317 is fixed, thus ensuring the reliable operation of the geared motor 318.

[0023] Based on the above scheme, since the outer wall of the rotating seat 38 is also provided with a pressure ring 315, and the first rotating sealing ring 313 is pressed on the tank cover 30 by the pressure ring 315, the first rotating sealing ring 313 is used to complete the seal between the tank cover 30 and the pressure ring 315, so as to prevent dust or impurities from entering the interior of the tank 1, thereby facilitating the direct alcohol fermentation inside the tank 1 after the saccharification of the rice wine.

[0024] Similarly, the inner wall of the rotating seat 38 is also provided with a support platform 310, and a second rotating sealing ring 314 is provided on the support platform 310. The sealing between the pressure cap 39 and the support platform 310 is completed by the second rotating sealing ring 314, so that the rotating seat 38 and the pressure cap 39 also have reliable sealing. After saccharification, alcohol fermentation is carried out directly inside the tank 1.

[0025] The first rotary sealing ring 313 and the second rotary sealing ring 314 are preferably rubber skeleton oil seals, and a waterproof bearing is installed at the connection between the first connecting pipe 312 and the gland 39 to reduce liquid leakage.

[0026] To facilitate the assembly and disassembly of the circulation pipe 31, nuts 32 are provided at both ends of the circulation pipe 31. One end of the circulation pipe 31 is connected to the first connecting pipe 312 via the nut 32, and the other end of the circulation pipe 31 is also connected to the second connecting pipe 312 via the nut 32. This makes the installation and replacement of the circulation pipe 31 simple and convenient. In particular, it facilitates the connection between the rotating seat 38 and the circulation pipe 31 from both sides of the can cover 30.

[0027] In addition, since the bottom of the tank 1 is also provided with a movable frame 4, and the outer wall surface of the tank 1 is also provided with a handrail 2, the tank 1 can be moved by pushing it with the handrail 2; wherein, the bottom surface of the movable frame 4 is provided with casters.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
