Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an automated food fermentation equipment. Background Technology

[0002] Food fermentation is a process that utilizes the metabolic activities of beneficial microorganisms to transform sugars, proteins, and other substances in food raw materials into flavor compounds, nutrients, or functional components that people need. For example, yogurt fermentation involves lactic acid bacteria converting lactose in milk into lactic acid, causing the milk to coagulate and produce a unique flavor; brewing involves yeast converting glucose into alcohol and carbon dioxide. In large-scale food production, traditional manual fermentation methods suffer from low efficiency, unstable quality, and high labor intensity, making it difficult to meet market demands. Therefore, automated food fermentation equipment has emerged. Automated equipment achieves automatic control of the fermentation process through mechanical structures and physical principles, including a series of operations such as material conveying, fermentation environment adjustment, and fermentation time control, which can effectively improve production efficiency and product quality stability.

[0003] The existing automated food fermentation equipment has the following shortcomings:

[0004] Traditional fermentation equipment relies solely on fixed scrapers to remove impurities adhering to the inner walls of the fermentation tank during cleaning. Due to the lack of a rinsing process, it is difficult to thoroughly remove stubborn stains and residual fermentation products, resulting in poor cleaning effects. Long-term use may also lead to bacterial growth, affecting the quality of subsequent fermentation. At the same time, existing stirring methods are relatively simple, mostly only achieving horizontal stirring. The food fermentation raw materials cannot form a three-dimensional mixing motion within the tank, resulting in uneven stirring. Some raw materials cannot fully contact microorganisms, leading to low fermentation efficiency and affecting the stability of product quality. Utility Model Content

[0011] Preferably, the stirring assembly includes a drive motor, which is fixedly connected to the top center of the fermentation tank, and the output shaft of the drive motor extends into the interior of the fermentation tank and is fixedly connected to a rotating column.

[0013] Preferably, a rotating sleeve is fixedly connected to the bottom end of the rotating column, and a rotating shaft that runs through the middle of the rotating sleeve is rotatably connected to the middle of the rotating sleeve. Stirring blades are fixedly connected to both the left and right sides of the outer surface of the rotating shaft.

[0016] Preferably, the bottom of the drive gear is fixedly connected to a connecting shaft, and the bottom end of the connecting shaft extends into the interior of the rotating sleeve and is fixedly connected to a bevel gear.

[0017] Preferably, a second bevel gear is meshed with the outer surface of the first bevel gear, and the middle part of the second bevel gear is fixedly connected to the middle part of the outer surface of the bottom end of the rotating shaft.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. In this utility model, when the cleaning component is working, water enters the annular water supply pipe through the water inlet pipe, then flows into the water supply trough inside the rotating scraper through the connecting hole, and finally sprays out from the spray hole to achieve spray cleaning of the inner wall of the fermentation tank. At the same time, the rotating scraper rotates with the annular rotating frame, and in addition to scraping off the impurities on the inner wall, it is combined with water rinsing to greatly improve the cleaning effect. In addition, the conical baffle at the spray hole normally fits the spray hole under the action of the tension spring to prevent fermentation raw materials from entering and causing blockage. During cleaning, the water pressure pushes open the conical baffle to ensure that the water flow is smooth. Through the mutual cooperation of the various components of the cleaning component, the problems of poor effect and easy residue of impurities in traditional cleaning methods are effectively solved, reducing the risk of bacterial growth, ensuring a clean fermentation environment, and providing a foundation for high-quality fermentation.

[0020] 2. In this utility model, when the stirring assembly is running, the drive motor drives the rotating column to rotate, and the rotating column drives the rotating shaft to rotate horizontally through the rotating sleeve, so that the stirring blades can achieve horizontal stirring. At the same time, during the rotation of the rotating column, the transmission wheel meshes with the transmission gear ring fixed at the top of the inner surface of the fermentation tank, driving the drive gear to rotate. The drive gear, through the transmission of the connecting shaft, bevel gear one and bevel gear two, causes the rotating shaft to rotate vertically, thereby allowing the stirring blades to stir vertically. The combination of horizontal and vertical stirring motions makes the food fermentation raw materials form a three-dimensional mixing motion in the tank, which greatly improves the stirring uniformity, allows the raw materials to fully contact the microorganisms, accelerates the fermentation process, and improves the fermentation efficiency and product quality stability.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes a fermenter 1, with a feed inlet 2 on the top left side and a discharge outlet 3 in the middle of the bottom of the fermenter 1. A cleaning assembly 4 is fixedly connected to the top right side of the fermenter 1, and a stirring assembly 5 is fixedly connected to the top middle of the fermenter 1. The cleaning assembly 4 includes an annular water supply pipe 41, which is fixedly connected to the top of the inner surface of the fermenter 1. An annular rotating frame 43 is rotatably connected to the bottom of the annular water supply pipe 41. Four connecting plates 44 are fixedly connected in an annular array on the inner surface of the annular rotating frame 43. The end of the connecting plate 44 away from the annular rotating frame 43 is fixedly connected to the outer surface of the rotating column 52. The bottom left and right sides of the annular rotating frame 43 are... A rotating scraper 45 is fixedly connected. The inner left and right sides of the annular rotating frame 43 are provided with through holes 431. The top of the through holes 431 extends into the interior of the annular water supply pipe 41. A water supply trough 451 is provided inside the rotating scraper 45. The bottom of the through holes 431 extends into the top of the water supply trough 451. Several spray holes 452 extending from front to back are provided on the inner surface of the water supply trough 451. A water inlet pipe 42 is fixedly connected to the top right side of the annular water supply pipe 41. The top of the water inlet pipe 42 extends into the top right side of the fermentation tank 1. Conical baffles 453 are movably engaged on the inner surface of the spray holes 452 on both the front and back sides. A tension spring 454 is fixedly connected to the opposite surfaces of the two conical baffles 453.

[0030] The effect achieved by the entire embodiment 1 is as follows: when it is necessary to clean the fermentation tank 1, the water source is connected to the water inlet pipe 42, and the water enters the annular water supply pipe 41 under pressure. Since the annular rotating frame 43 is rotatably connected to the annular water supply pipe 41, and the connecting plate 44 connects the annular rotating frame 43 to the rotating column 52, when the stirring assembly 5 is working, the rotating column 52 drives the annular rotating frame 43 to rotate. At this time, the water flows into the water supply trough 451 of the rotating scraper 45 through the connecting hole 431 in the annular rotating frame 43. During the rotation of the rotating scraper 45, the water is sprayed out from the spray hole 452 of the water supply trough 451 to spray and rinse the inner wall of the fermentation tank 1. Meanwhile, the rotating scraper 45 continuously scrapes the inner wall of the fermentation tank 1, scraping off the attached impurities. Combined with the water flow, the impurities are washed away, greatly improving the cleaning effect. When not cleaning, the tension spring 454 pulls the conical baffle 453 to fit against the water spray hole 452, preventing fermentation raw materials from entering the water spray hole 452 and causing blockage. During cleaning, the pressure generated by the water flow overcomes the tension of the tension spring 454, pushing open the conical baffle 453, allowing the water to spray out smoothly, ensuring that the cleaning work is carried out normally, effectively protecting the cleanliness of the inside of the fermentation tank 1, and providing a good environment for subsequent fermentation operations.

[0031] Example 2: Figure 4 and Figure 5 As shown, this utility model provides a technical solution: the stirring assembly 5 includes a drive motor 51, which is fixedly connected to the top center of the fermentation tank 1. The output shaft of the drive motor 51 passes through the interior of the fermentation tank 1 and is fixedly connected to a rotating column 52. A rotating sleeve 53 is fixedly connected to the bottom end of the rotating column 52. A rotating shaft 54, which passes through the left and right sides, is rotatably connected to the middle of the rotating sleeve 53. Stirring blades 55 are fixedly connected to both sides of the outer surface of the rotating shaft 54. A movable groove is opened at the top of the outer surface of the rotating column 52, and a drive motor 55 is rotatably connected inside the movable groove. The outer surface of the drive gear 521 is meshed with a transmission wheel 522, and the outer surface of the transmission wheel 522 is meshed with a transmission gear ring 523. The transmission gear ring 523 is fixedly connected to the top of the inner surface of the fermentation tank 1. The bottom of the drive gear 521 is fixedly connected with a connecting shaft 524. The bottom end of the connecting shaft 524 passes through the interior of the rotating sleeve 53 and is fixedly connected with a bevel gear 531. The outer surface of the bevel gear 531 is meshed with a bevel gear 532, and the middle part of the bevel gear 532 is fixedly connected to the middle part of the outer surface of the bottom end of the rotating shaft 54.

[0032] The overall effect of Embodiment 2 is as follows: The drive motor 51 is started, which drives the rotating column 52 to rotate. The rotating column 52 drives the rotating shaft 54 ​​to rotate horizontally through the rotating sleeve 53. At this time, the stirring blade 55 fixed on the rotating shaft 54 ​​performs horizontal stirring motion, initially mixing the raw materials in the fermentation tank 1. Simultaneously, when the rotating column 52 rotates, the transmission wheel 522 rotates under the action of the transmission gear ring 523. Since the transmission wheel 522 meshes with the drive gear 521, it drives the drive gear 521 to rotate. The drive gear 521 drives the first bevel gear 531 to rotate through the connecting shaft 524. The first bevel gear 531 meshes with the second bevel gear 532, causing the rotating shaft 54 ​​to rotate vertically on the basis of horizontal rotation. The stirring blade 55 also performs vertical stirring motion. The combination of horizontal and vertical stirring motions allows the food fermentation raw materials to form a three-dimensional mixing motion in the fermentation tank 1. The raw materials can be fully mixed in all directions, greatly improving the mixing uniformity, ensuring that the raw materials and microorganisms are in full contact, effectively accelerating the fermentation process, and improving fermentation efficiency and product quality stability.

[0033] The working principle of the entire equipment is as follows: When carrying out food fermentation, the food fermentation raw materials are first transported into the fermentation tank 1 through the feed inlet 2. The drive motor 51 is started, and the stirring component 5 starts to work. The drive motor 51 drives the rotating column 52 to rotate. On the one hand, the rotating column 52 drives the rotating shaft 54 ​​and the stirring blade 55 to rotate horizontally through the rotating sleeve 53. On the other hand, during the rotation of the rotating column 52, the transmission wheel 522 meshes with the transmission gear ring 523 fixed at the top of the inner surface of the fermentation tank 1, which drives the drive gear 521 to rotate. The drive gear 521 is transmitted through the connecting shaft 524, bevel gear one 531 and bevel gear two 532, so that the rotating shaft 54 ​​rotates vertically. The stirring blade 55 stirs the raw materials in both horizontal and vertical directions, realizing three-dimensional mixing of the raw materials and promoting the fermentation reaction.

[0034] After fermentation is complete, the discharge port 3 is opened, and the fermented material is discharged from the discharge port 3 under gravity or through an auxiliary conveying device. When it is necessary to clean the fermentation tank 1, the water source is connected to the water inlet pipe 42, and the water enters the annular water supply pipe 41. Since the annular rotating frame 43 is connected to the rotating column 52 through the connecting plate 44, the rotating column 52 will drive the annular rotating frame 43 to rotate when it rotates. At this time, the water flows into the water supply trough 451 of the rotating scraper 45 through the connecting hole 431 and is sprayed out from the spray hole 452 to spray and wash the inner wall of the fermentation tank 1. At the same time, the rotating scraper 45 scrapes the inner wall to remove impurities. With the cooperation of the tension spring 454 and the conical baffle 453, it is ensured that the spray hole 452 is not blocked and can spray water normally, thereby completing the efficient cleaning of the fermentation tank 1 and preparing for the next fermentation operation.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
