Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a fermentation device for multi-flavored fresh milk yogurt. Background Technology

[0002] Yogurt is a dairy product made through fermentation. Its production process mainly includes the following steps: First, fresh milk is pasteurized to kill harmful microorganisms while retaining nutrients; then, specific probiotics are inoculated in a sterile environment, and fermentation occurs at a suitable temperature, converting lactose in the milk into lactic acid; after curdling, the fermentation process is stopped by cooling, and finally, it is aseptically filled and packaged. This fermentation process not only gives yogurt its unique sweet and sour taste but also produces a group of active probiotics beneficial to the human body.

[0003] Extensive searching revealed CN207054679U, which discloses a yogurt fermentation device including a tank, a top cover, a stirring shaft, and a geared motor. The top cover is sealed to the tank and has a manhole and a feed inlet. The stirring shaft is located inside the tank, with its upper end passing through the top cover and fixedly connected to the output shaft of the geared motor. The geared motor is also fixedly connected to the top cover. A discharge outlet is located at the lower end of the tank. This device effectively cleans the inside of the tank while conserving water resources.

[0004] When fermenting yogurt, it is necessary to stir the yogurt regularly to improve the fermentation efficiency. Existing stirring structures usually adopt a single-shaft stirring blade layout. The shear force generated when it rotates is mainly concentrated in the middle and bottom areas of the tank, resulting in obvious laminar flow inside the fermentation liquid, which leads to relatively low fermentation efficiency. To address this issue, a fresh milk multi-flavored yogurt fermentation device is proposed. Utility Model Content

This solves the problem that when existing yogurt fermentation devices rotate, the shear force is concentrated in the middle and bottom areas of the tank, causing obvious laminar flow inside the fermentation liquid and resulting in low fermentation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fresh milk multi-flavored yogurt fermentation device, comprising a barrel, wherein a conical bottom groove is provided at the bottom of the barrel, and a first reserved groove and a second reserved groove are respectively provided on both sides of the outer wall of the barrel.

[0011] In the design, the exhaust pipe is rotatably connected to the support frame, allowing for flexible adjustment of the exhaust pipe's angle and direction, facilitating the removal of the cover. A quick-connect coupling at one end of the exhaust pipe enables rapid connection and disconnection with the exhaust end on the top of the cover. A manual pressure relief valve at the other end of the exhaust pipe allows for manual control of pressure relief based on the pressure inside the tank, ensuring safe operation of the device. A pressure gauge installed on the exhaust pipe between the manual pressure relief valve and the quick-connect coupling enables real-time monitoring of pressure changes inside the tank, providing operators with accurate pressure data.

[0012] Preferably, the exhaust assembly includes an exhaust pipe, which is rotatably connected to the support frame via a rotary joint. One end of the exhaust pipe is provided with a quick-connect fitting, and the other end of the exhaust pipe is equipped with a manual pressure relief valve. A pressure gauge is provided on the exhaust pipe between the manual pressure relief valve and the quick-connect fitting.

[0013] In the design, the exhaust pipe is rotatably connected to the support frame via a rotary joint, allowing for flexible adjustment of the exhaust pipe's angle and direction, facilitating exhaust operation. A quick-connect fitting at one end of the exhaust pipe enables rapid connection and disconnection with the exhaust end on the top of the cover. A manual pressure relief valve at the other end of the exhaust pipe allows for manual control of exhaust pressure relief based on the pressure inside the tank, ensuring safe operation of the device.

[0014] Preferably, the top of the cover is provided with an exhaust end, and the exhaust end and the quick-connect connector of the exhaust assembly form a detachable snap-fit ​​structure. The upper surface of the cover is fixedly provided with lifting hooks in a ring array.

[0015] In the design, by setting an exhaust end on the top of the cover and forming a detachable snap-fit ​​structure with the quick-connect joint of the exhaust component, the exhaust component can be easily connected and disassembled, which facilitates the maintenance and cleaning of the fermentation device. By fixing lifting hooks in a ring array on the upper surface of the cover, the cover can be easily lifted by lifting equipment, reducing the burden of manual operation.

[0016] Preferably, the bottom end of the conical trough is provided with a discharge port and connected to a discharge pipe, a manual discharge valve is fixedly installed on the discharge pipe, and a support frame is fixedly provided on the outer side of the outer wall of the conical trough.

[0017] In the design, by opening a discharge port at the bottom of the conical trough and connecting it with a discharge pipe, the function of smoothly discharging the fermented yogurt from the fermentation device is realized; by fixing a manual discharge valve on the discharge pipe, the purpose of manually controlling the discharge speed and flow rate as needed is realized; by fixing a support frame on the outer side of the conical trough, a stable support is provided for the fermentation device, ensuring that the device remains stable during operation.

[0020] Preferably, the stirring filter plate is made of stainless steel, and the surface of the stirring filter plate has a number of filter holes evenly distributed.

[0021] In the design, the use of stainless steel to make the stirring filter plate ensures that the stirring filter plate has good corrosion resistance and strength, and extends its service life. By evenly distributing several filter holes on the surface of the stirring filter plate, the fermentation broth can pass through the filter holes better during the stirring process, which further enhances the stirring and mixing effect and improves the fermentation efficiency.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention achieves a three-dimensional mixing effect by setting up a stirring filter plate with an elliptical cross-section structure and one side in contact with the inner wall of the barrel, and a mixing assembly with a drive motor installed on the outer wall of the barrel and driving the stirring filter plate to rotate through the transmission end.

[0024] When the drive motor rotates the stirring filter plate, the elliptical stirring plate produces varying stirring effects at different positions within the tank. During rotation, in addition to generating a conventional radial stirring force on the fermentation broth, it also creates a complex flow field along the circumference of the tank due to its contact with the inner wall. This flow field drives the fermentation broth to flow in the axial, radial, and circumferential directions, thus breaking the laminar flow phenomenon caused by existing single-shaft stirring blade layouts. This ensures that the fermentation broth is thoroughly stirred throughout the entire tank, avoiding the problem of shear force concentration in the middle and bottom areas of the tank. It allows various components in the fermentation broth, such as fresh milk and probiotics, to mix and contact more evenly, thereby improving fermentation efficiency and ensuring the quality of yogurt fermentation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] When the drive motor 31 rotates the stirring filter plate 32, the elliptical stirring filter plate 32 produces different stirring effects at different positions within the tank 1. During rotation, in addition to generating a conventional radial stirring force on the fermentation liquid within the tank 1, it also forms a complex flow field in the circumferential direction of the tank 1 due to its contact with the inner wall of the tank 1.

[0044] In the design, by setting an exhaust end 22 on the top of the cover 2 and forming a detachable snap-fit ​​structure with the quick-connect joint 51 of the exhaust component 5, the function of convenient connection and disassembly of the exhaust component 5 is realized, which facilitates the maintenance and cleaning of the fermentation device; by fixing the lifting hooks 21 in a ring array on the upper surface of the cover 2, the function of convenient use of lifting equipment to lift the cover 2 is realized, which reduces the burden of manual operation.

[0045] Example 3

[0046] To ensure the smooth discharge of fermented yogurt, facilitate observation of the fermentation process, and improve stirring efficiency, etc. Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the bottom end of the conical bottom groove 11 is provided with a discharge port and connected to a discharge pipe 112. A manual discharge valve 113 is fixedly installed on the discharge pipe 112, and a base frame 111 for support is fixedly provided on the outer side of the outer wall of the conical bottom groove 11.

[0047] In the design, by opening a discharge port at the bottom of the conical bottom trough 11 and connecting it with a discharge pipe 112, the function of smoothly discharging the fermented yogurt from the fermentation device is realized; by fixing a manual discharge valve 113 on the discharge pipe 112, the purpose of manually controlling the discharge speed and flow rate as needed is realized; by fixing a support frame 111 on the outer side of the outer wall of the conical bottom trough 11, a stable support is provided for the fermentation device, ensuring that the device remains stable during operation.

[0048] Furthermore, an observation window 4 is installed and fixed in the first reserved slot 13. The observation window 4 is made of double-layer tempered glass with a laminated structure.

[0049] The design incorporates a fixed observation window 4 at the first reserved slot 13, enabling operators to observe the state of the fermentation liquid and the stirring process inside the tank 1 at any time, thus facilitating timely monitoring of the fermentation process. The observation window 4 is constructed using a double-layer tempered glass laminated structure, ensuring good strength and transparency while also possessing certain explosion-proof properties to guarantee the safety of operators.

[0050] Furthermore, the stirred filter plate 32 is made of stainless steel, and several filter holes are evenly distributed on the surface of the stirred filter plate 32.

[0051] In the design, the stirring filter plate 32 is made of stainless steel, which ensures that the stirring filter plate 32 has good corrosion resistance and strength and extends its service life. By uniformly distributing a number of filter holes on the surface of the stirring filter plate 32, the fermentation liquid can pass through the filter holes better during the stirring process, which further enhances the stirring and mixing effect and improves the fermentation efficiency.

[0052] When using this invention, open the lid 2 and rinse the inside of the bucket 1 and the conical bottom groove 11 with clean water to remove impurities and dust. Use a suitable disinfectant to disinfect the parts that come into contact with the yogurt, such as the bucket 1, the stirring filter plate 32, and the lid 2, to ensure that the inside of the device is sterile. After disinfection, rinse with sterile water and let it air dry.

[0053] Fresh, pasteurized milk and specific probiotics are added to the container 1 through the open lid 2. The lid 2 is then closed, and the vent end 22 at the top of the lid 2 is detachably engaged with the quick-connect fitting 51 of the venting assembly 5, ensuring a tight connection to prevent air leakage. The manual pressure relief valve 53 is checked to ensure it is closed, and the pressure gauge 54 is at zero. The drive motor 31 of the mixing assembly 3 is started, causing the drive end of the motor 31 to rotate the stirring filter plate 32 inside the container 1. Because the stirring filter plate 32 has an elliptical cross-section and one side contacts the inner wall of the container 1, it can thoroughly stir the fermentation liquid during rotation, promoting uniform mixing of the raw materials and improving fermentation efficiency. The stirring process can be observed through the observation window 4.

[0054] Adjust the fermentation temperature and time parameters according to the requirements of yogurt fermentation. During fermentation, gas will be produced by the fermentation reaction, causing the pressure inside container 1 to rise. The pressure can be released by observing the value of pressure gauge 54 and opening manual pressure relief valve 53 in a timely manner to maintain the pressure inside container 1.

[0055] Once fermentation reaches the predetermined time and curdling occurs, turn off the drive motor 31 to stop the rotation of the stirring filter plate 32. Slowly open the manual discharge valve 113 on the discharge pipe 112, allowing the fermented yogurt to flow out through the discharge pipe 112 from the discharge port at the bottom of the conical trough 11, and be collected into a suitable container for subsequent cooling, aseptic filling, and sealing operations. During the discharge process, the remaining amount of yogurt in the container 1 can be observed through the observation window 4 to ensure complete discharge.
