Detailed Description of the Invention

[0020] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are for illustrative purposes in nature and not intended to limit the present invention.

[0021] To further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0022] Referring to Figures 1 to 3 , an embodiment of the present application provides an upper and lower double - bin fermented milk to - be - canned 100, which includes a bin 10 and a connecting barrel section 20. Among them, there are two bins 10, and the two bins 10 are respectively an upper bin 11 and a lower bin 12, and the upper bin 11 and the lower bin 12 are arranged vertically one above the other. An accommodating cavity 13 is provided inside each of the two bins 10, and the accommodating cavity 13 is used to accommodate fermented milk, and the accommodating cavity 13 of the upper bin 11 and the accommodating cavity 13 of the lower bin 12 are independent of each other.

[0023] The connecting barrel section 20 is columnar with openings at both ends and hollow inside. The top of the connecting barrel section 20 is connected to the bottom of the upper bin 11, and the bottom of the connecting barrel section 20 is connected to the top of the lower bin 12, so that the upper bin 11 and the lower bin 12 are arranged vertically one above the other.

[0024] For the upper and lower double - bin fermented milk to - be - canned 100 of the present application, it is a subsequent process for the base material to cool down after maturing in the fermenter and is used in the previous process of fermented milk filling. The working medium of the upper and lower double - bin fermented milk to - be - canned 100 is the fermented milk after cooling. By providing two bins 10 in the upper and lower double - bin fermented milk to - be - canned 100, the two bins 10 can respectively hold fermented milk, improving the flexibility of use of the upper and lower double - bin fermented milk to - be - canned 100. At the same time, the upper bin 11 and the lower bin 12 are arranged vertically one above the other, and the two bins 10 are formed by vertically stacking one above the other, which can effectively reduce the land occupation area, save resources, and make the equipment more centralized.

[0025] In this embodiment, the basic structures of the upper bin 11 and the lower bin 12 are the same. First, the basic structures of the two will be introduced. After the basic structures of the bin 10 (upper bin 11, lower bin 12) are introduced, the differences between the upper bin 11 and the lower bin 12 will be introduced respectively.

[0026] Both of the two silos 10 in this embodiment include a cylinder body 14, a top head 15 provided at the top of the cylinder body 14, and a bottom head 16 provided at the bottom of the cylinder body 14. Among them, the cylinder body 14 is cylindrical with openings at both ends and a hollow interior. Both the top head 15 and the bottom head 16 are conical, and both are conical with a large cone angle. The top head 15, the cylinder body 14, and the bottom head 16 are connected to form a receiving cavity 13 for receiving fermented milk inside the silo 10.

[0027] The working pressure of the fermented milk in the receiving cavity 13 of the silo 10 is generally 1 atm. Under working conditions, the temperature change range inside the silo 10 is 1 °C / 24 h, and the roughness of the inner wall of the silo 10 is not greater than 0.6 μm.

[0028] In this embodiment, the opening angle of the top head 15 of the silo 10 is generally 140° or 150°. In actual design, when the diameter of the cylinder body 14 is less than or equal to 2.5 m, the cone angle of the top head 15 is 150°; when the diameter of the cylinder body 14 is greater than 2.5 m, the cone angle of the top head 15 is 140°.

[0029] In this embodiment, the opening angle of the bottom head 16 of the silo 10 is generally 120°, 140°, or 150°. In actual design, the size of the opening angle of the bottom head 16 is related to the diameter of the cylinder body 14 and the viscosity of the medium inside the receiving cavity 13. When the medium with high viscosity is contained inside the receiving cavity 13, the cone angle of the bottom head 16 is 120°. When the working medium in the receiving cavity 13 is similar to clear water and the diameter of the cylinder body 14 is less than 2.0 m, the cone angle of the bottom head 16 can be set to 150°; when the working medium in the receiving cavity 13 is similar to clear water and the diameter of the cylinder body 14 is greater than or equal to 2.0 m, the cone angle of the bottom head 16 can be set to 140°.

[0030] The upper silo 11 and the lower silo 12 are connected through a connecting cylinder section 20. The connecting cylinder section 20 in this embodiment includes a first cylinder section 21 and a second cylinder section 22. The top of the first cylinder section 21 is connected to the outside of the bottom head 16 of the upper silo 11, and the bottom of the second cylinder section 22 is connected to the outside of the top head 15 of the lower silo 12. The bottom of the first cylinder section 21 is fixedly welded to the top of the second cylinder section 22 so that the upper silo 11 and the lower silo 12 are arranged vertically one above the other.

[0031] Inside the connecting cylinder section 20, there is a spacing between the bottom head 16 of the upper silo 11 and the top head 15 of the lower silo 12. In this embodiment, the upper and lower double - silo fermented milk to be canned 100 further includes a skirt support 30. The skirt support 30 is connected to the bottom of the lower silo 12 to stably support the upper silo 11 and the lower silo 12 on the ground.

[0032] The feed bin 10 of this embodiment is provided with a feed port 171 for feeding fermented milk. The feed port 171 is provided on the top seal 15 and is arranged near the connection between the cylinder 14 and the top seal 15.

[0033] In this embodiment, the silo 10 also includes a feed pipe 172. This feed pipe 172 comprises a straight section 1721 and a curved section 1722 connected to the straight section 1721. The straight section 1721 is fixedly mounted in the feed port 171, while the curved section 1722 is disposed within the receiving chamber 13 of the silo 10. One end of the curved section 1722 is bent and connected to the bottom end of the straight section 1721, while the other end is positioned near the inner wall of the cylinder 14, maintaining a certain feed spacing with the inner wall. In this embodiment, this feed spacing is 0.25 times the diameter of the feed pipe 172.

[0034] When the fermented milk enters the silo 10 through the feed pipe 172 , the fermented milk can flow down along the inner wall of the cylinder 14 via the guidance of the curved pipe section 1722 , thereby preventing the fermented milk from directly entering the accommodating cavity 13 and generating foam on the liquid surface inside the silo 10 .

[0035] In this embodiment, the straight pipe section 1721 is vertically arranged in the feed port 171, and the angle between the curved pipe section 1722 and the straight pipe section 1721 is set to be no less than 120°, such as 150°.

[0036] When fermented milk enters silo 10 through feed pipe 172, it can be guided by curved pipe section 1722 and rotated tangentially downward along the inner wall of cylinder 14. The angle between curved pipe section 1722 and the normal to the pipe can be set at 60° to prevent the fermented milk from flowing directly into accommodating chamber 13, thereby preventing foam from splashing on the liquid surface inside silo 10. Straight pipe section 1721 is vertically inserted into feed port 171. The angle between curved pipe section 1722 and straight pipe section 1721 can be set to be greater than or equal to 120°, so that the feeding direction is aligned with the rotation direction of agitator 191 and faces away from the manhole.

[0037] The above arrangement is to form an anti-foaming inlet to prevent the imported milk from falling directly onto the liquid surface in the tank and generating foam. At the same time, the feeding direction is the same as the rotation direction of the agitator 191 and is opposite to the manhole, so that the milk enters the tank and rotates downward along the inner wall tangentially.

[0038] In this embodiment, the feed pipe 172 of the lower silo 12 also includes an extension pipe section 1723. This extension pipe section 1723 connects to the other end of the straight pipe section 1721, away from the curved pipe section 1722. This extension pipe section 1723 is arranged horizontally and connects to the straight pipe section 1721 via an elbow. The extension pipe section 1723 is inserted into the connecting barrel section 20, so that the inlet of the lower silo 12 is arranged outside the connecting barrel section 20.

[0039] The silo 10 of this embodiment is also provided with a breather port 173, which is arranged on the top head 15 and communicates with the accommodating cavity 13. By providing the breather port 173, it can be avoided that a vacuum is formed inside the accommodating cavity 13 due to sudden temperature changes during the discharging process and cleaning of the silo 10, preventing the silo 10 from being damaged due to the vacuum state and ensuring the structural stability of the silo 10.

[0040] In this embodiment, the silo 10 further includes a breather pipe 174. One end of the breather pipe 174 is bent and connected to the breather port 173, and the other end extends vertically downward to the bottom of the upper and lower double-chamber fermented milk storage tank 100 and is used to communicate with the aseptic workshop. In the aseptic workshop, a funnel 1741 is provided at the end of the breather pipe 174, and the funnel 1741 is used to collect water vapor.

[0041] By connecting the end of the breather pipe 174 to the aseptic workshop, it can effectively prevent the air in the outdoor environment from polluting the fermented milk in the silo 10 and ensure the storage quality of the fermented milk. The breather pipes 174 of the upper silo 11 and the lower silo 12 in this embodiment are independent of each other, and heat preservation plates are provided on the outer peripheral side walls of the breather pipes 174 of the upper silo 11 and the lower silo 12 to effectively enhance the heat preservation effect.

[0042] In this embodiment, a pipe body cleaning port 1742 is provided at the top end of the breather pipe 174, and a pipe body cleaning pipe 1743 is provided at the pipe body cleaning port 1742. The end of the pipe body cleaning pipe 1743 extends into the interior of the breather pipe 174, and a washing ball is provided at the end of the pipe body cleaning pipe 1743 for cleaning the interior of the breather pipe 174 to avoid the situation of bacterial contamination caused by the residue of fermented milk.

[0043] A silo cleaning port 175 is also provided on the top head 15 of the silo 10 of this embodiment, and the silo cleaning port 175 is arranged at the top end of the top head 15. The silo 10 is also provided with a silo cleaning pipe 176, and the silo cleaning pipe 176 passes through the silo cleaning port 175. A washing ball is provided at the end of the silo cleaning pipe 176 extending into the accommodating cavity 13 of the silo 10. By providing the silo cleaning pipe 176, the accommodating cavity 13 of the silo 10 can be cleaned to avoid the situation of cross-contamination caused by the residue of different types of fermented milk stored in the silo 10.

[0044] A high-level switch interface 177 is also provided on the top head 15 of the silo 10, and a high-level sensor is provided at the high-level switch interface 177. The high-level sensor is used to measure the high-level value in the accommodating cavity 13 of the silo 10. Correspondingly, a low-level switch interface 178 is provided on the bottom head 16 of the silo 10, and the low-level switch interface 178 is arranged close to the bottom end of the bottom head 16. A low-level sensor is provided at the low-level switch interface 178 for measuring the low-level value in the accommodating cavity 13 of the silo 10.

[0045] The bottom head 16 of the silo 10 in this embodiment is provided with a discharge port 179, and the discharge port 179 is arranged at the bottom end of the bottom head 16. The silo 10 further includes a discharge pipe 180, and the discharge pipe 180 is communicated with the discharge port 179. The discharge pipe 180 includes a transition section 181 communicated with the discharge port 179 and an extension section 182 communicated with the transition section 181.

[0046] Among them, the transition section 181 is a bent pipe, and the extension section 182 is arranged to incline downward relative to the horizontal plane. In this embodiment, the included angle between the extension section 182 and the horizontal plane is 1°, so that the fermented milk in the accommodating cavity 13 of the silo 10 can flow out smoothly, facilitating the efficient transportation and unloading of the fermented milk.

[0047] For the upper feeding silo 11 of the fermented milk to be filled into the upper and lower double-chamber can 100, the discharge pipe 180 of the upper feeding silo 11 penetrates through the connecting barrel section 20 and extends out of the connecting barrel section 20. For the lower feeding silo 12 of the fermented milk to be filled into the upper and lower double-chamber can 100, the discharge pipe 180 of the lower feeding silo 12 penetrates through the skirt support 30 and extends out of the skirt support 30.

[0049] A stirrer interface 1832 is further arranged on the cylinder small chamber 183, and a stirrer 191 is arranged at the stirrer interface 1832. The stirrer 191 extends into the accommodating cavity 13. The stirrer 191 is a blade stirrer and is used for stirring the fermented milk in the accommodating cavity 13.

[0050] A stirrer cleaning port 1833 is provided near the stirrer interface 1832, and a stirrer cleaning pipe 192 is provided at the stirrer cleaning port 1833. The stirrer cleaning pipe 192 extends into the accommodation cavity 13, and the extending direction of the stirrer cleaning pipe 192 is the same as that of the stirrer 191. A washing ball 193 is provided at the end of the stirrer cleaning pipe 192, and the washing ball 193 is used to clean the stirrer 191 to prevent the situation of bacterial growth and contamination caused by the residue of fermented milk.

[0051] The upper and lower double-chamber fermented milk to-be-filled can 100 of this embodiment further includes an outer wrapper 40 and a connecting ring 50. Among them, the outer wrapper 40 includes a cylindrical outer wrapper 41 and a conical outer wrapper 42.

[0052] The cylindrical outer wrapper 41 is in the shape of a column with both ends open. The cylindrical outer wrapper 41 is arranged around the outer circumferences of the cylinder 14 of the feeding bin 11, the connecting cylinder section 20, and the cylinder 14 of the discharging bin 12. The bottom of the cylindrical outer wrapper 41 is fixed to the skirt support 30. By providing the cylindrical outer wrapper 41, the feeding bin 11, the connecting cylinder section 20, and the discharging bin 12 can present an integrated structure in appearance, making the appearance of the upper and lower double-chamber fermented milk to-be-filled can 100 more beautiful. At the same time, a sandwich layer is formed between the cylindrical outer wrapper 41 and the outer walls of the cylinder 14 of the bin 10 and the connecting cylinder section 20, and a heat-insulating material 60 is provided in the sandwich layer, which can insulate the interior of the bin 10 to realize the outdoor installation of the upper and lower double-chamber fermented milk to-be-filled can 100. The heat-insulating material 60 can be polyurethane with a thickness of 100 mm.

[0053] In this embodiment, the conical outer wrapper 42 is in a conical shape. There are multiple conical outer wrappers 42. The conical outer wrapper 42 is provided on the outside of the top head 15 and the bottom head 16 of the feeding bin 11, and the conical outer wrapper 42 is also provided on the outside of the top head 15 and the bottom head 16 of the discharging bin 12.
