Description

Technical Field

[0001] This utility model relates to the field of milk conveying devices, and in particular to an online milk heating and conveying device. Background Technology

[0002] In dairy processing, the online heating of milk is crucial, especially for fermented products such as yogurt and cheese. Before bottling, milk must be heated to a specific temperature to eliminate unwanted bacteria, thus ensuring a stable and controllable fermentation process. Figure 1 The demonstrated online milk heating device delivers milk via pipeline to the heating unit, where it is heated before being output. However, manufacturers also produce products that do not require heating before entering the filling machine, such as chilled milk. These products require filling at low temperatures to preserve their unique nutrients and flavor. In this case, the milk does not need to pass through a heating unit; instead, it is delivered directly to the filling machine via pipeline.

[0003] To save on equipment costs, some manufacturers have added bypass valves to their online milk heating systems, such as... Figure 1 As shown. When conveying milk that does not require heating, the heating device 4 is turned off and the bypass valve 6 is opened; conversely, the bypass valve 6 is closed and the heating device 4 is started. To ensure the safe conveying of milk products, the entire online heating and conveying device must be thoroughly cleaned after each stage of production. However, because some manufacturers produce heated milk more frequently than unheated milk, the bypass valve may remain closed for extended periods. Furthermore, the sizes of the bypass valve 6 and the closing valve of the heating device 4 are inconsistent, which can easily lead to the omission of bypass valve lines during cleaning, resulting in quality problems in subsequent batches and increased processing costs.

[0004] Therefore, there is an urgent need to introduce an improved online milk heating and conveying device. This device not only has the function of flexibly switching between milk heating and direct conveying, but also ensures that the entire system achieves a comprehensive and thorough effect during the cleaning process, thereby effectively avoiding any cleaning omissions and improving production efficiency and product quality.

[0018] As a preferred embodiment of this invention, the outer walls of the second and fourth conveying pipes are covered with a layer of heat-insulating material. The heat-insulating material layer effectively reduces heat conduction and maintains a stable temperature of the milk inside the pipes.

[0019] In a preferred embodiment of this invention, flow valves are connected to the third and fourth conveying pipes, and a temperature meter is installed on the fourth conveying pipe. This allows for precise control of the milk temperature. These devices can be connected to a control system to automatically adjust the heating amount.

In use, when conveying milk that does not require heating, the two ends of the bypass pipe are connected to the first and second conveying pipes respectively. When conveying milk that requires heating, the bypass pipe is disassembled and cleaned. The two ends of the heating device are then connected to the first and second conveying pipes respectively. During cleaning, cleaning agent can be directly applied to the heating section of the system, ensuring that the bypass pipe is not missed during cleaning.

[0037] Example 1

[0038] To save on equipment costs, some manufacturers have added bypass valves to their online milk heating systems, such as... Figure 1 As shown. When conveying milk that does not require heating, the heating device 4 is turned off and the bypass valve 6 is opened; conversely, the bypass valve 6 is closed and the heating device 4 is started. To ensure the safe conveying of milk products, the entire online heating and conveying device must be thoroughly cleaned after each stage of production. However, because some manufacturers produce heated milk more frequently than unheated milk, the bypass valve may remain closed for extended periods. Furthermore, the sizes of the bypass valve 6 and the closing valve of the heating device 4 are inconsistent, which can easily lead to the omission of bypass valve lines during cleaning, resulting in quality problems in subsequent batches and increased processing costs.

[0042] In some embodiments, the first conveying pipe 1 and the second conveying pipe 2 are both arranged vertically at intervals; the outlet of the first conveying pipe 1 is located at the bottom end, and the inlet of the second conveying pipe 2 is located at the bottom end.

[0043] In some embodiments, the bypass pipe 3 is a U-shaped pipe.

[0045] In some embodiments, the bypass pipe 3 is a component made of stainless steel 316. This material has excellent corrosion resistance, can resist acidic substances and other corrosive components in milk, and has a very smooth inner surface, reducing the possibility of milk accumulation and bacterial growth in the pipe, making it easy to clean, thereby ensuring the hygiene and safety of the milk.

[0047] In some embodiments, the outer walls of the second conveying pipe 2 and the fourth conveying pipe 42 are covered with a layer of insulating material. The insulating material layer can effectively reduce heat conduction and maintain a stable temperature of the milk inside the pipes.

[0048] In some embodiments, flow valves 421 are connected to the third delivery pipe 41 and the fourth delivery pipe 42, and a temperature meter 422 is provided on the fourth delivery pipe 42.
