Description

Technical Field

[0001] The utility model relates to the field of milk sterilization equipment, in particular to a sterilization device capable of efficiently retaining active substances in milk. Background Art

[0002] Cow's milk contains a variety of biologically active substances, such as bioactive enzymes, immunoglobulins, lactoferrin and bioactive peptides, which are beneficial to enhance human immunity and promote bone and brain development.

[0003] During the production and transportation of milk, it inevitably comes into contact with the surrounding air and equipment, making it susceptible to bacterial contamination. Moreover, milk is rich in nutrients and is more suitable for the rapid reproduction of microorganisms. Therefore, it needs to be sterilized to prevent the milk from spoiling and thus extend its shelf life.

[0004] Ultra-high temperature instantaneous sterilization is a relatively common method for sterilizing milk. As the milk flows downward, the upward movement of high-temperature steam allows the steam to directly contact the milk, heating it at ultra-high temperatures for several seconds, and then quickly cooling it to room temperature, killing bacteria in microorganisms such as Escherichia coli, Salmonella and Staphylococcus aureus by heat killing.

[0005] As the milk flows downward, the surface milk comes into contact with the steam and reaches a higher temperature first, while the milk inside heats up slowly. In order to ensure the sterilization effect, it is usually necessary to increase the steam temperature or extend the heating time. In addition, the cooling rate is slow, resulting in the surface milk temperature being too high or the heating time being too long, making it difficult to retain more active substances. Improvements are needed. Utility Model Content

[0006] The purpose of the utility model is to provide a sterilization device which can efficiently retain the active substances in milk, thereby ensuring the sterilization effect of milk and retaining more active substances.

The steam injection pipe has injection holes spaced apart in the height direction. A first flow distribution plate and a second flow distribution plate are spaced apart in the upper and lower parts of the rapid cooling box, forming a cold water chamber between the first flow distribution plate and the second flow distribution plate. Several cooling guide pipes are provided between the first flow distribution plate and the second flow distribution plate. A water inlet pipe joint connected to the cold water chamber is provided on one side of the rapid cooling box, and a water outlet pipe joint connected to the cold water chamber is provided on the other side of the rapid cooling box.

[0009] Among them, the milk dripping assembly includes a milk dispersion box, a filter screen and a cloth flow cover. The filter screen is arranged in the milk dispersion box. The top of the milk dispersion box is provided with an inlet connected to the milk inlet pipe joint. The cloth flow cover is arranged at the bottom of the milk dispersion box for sealing.

[0018] like Figure 1 The sterilization device shown in the figure for efficiently retaining the active substances in milk includes: a high-temperature sterilization box 1, a rapid cooling box 2, a milk junction box 3, a milk dripping assembly 5 and a steam injection pipe 4. The high-temperature sterilization box 1 is arranged on the top of the rapid cooling box 2, and the milk junction box 3 is arranged at the bottom of the rapid cooling box 2. A first cover plate 7 is provided on the top of the high-temperature sterilization box 1 and is fixed by bolts. The structure is firm and easy to disassemble and assemble.

[0019] A milk introduction pipe joint 8 is provided on the first cover plate 7 , and the milk dripping assembly 5 is placed in a high-temperature sterilizer and connected to the milk introduction pipe joint 8 . The milk introduction pipe joint 8 is externally connected to a milk pumping pipe to deliver milk into the milk dripping assembly 5 .

[0020] like Figure 2 As shown, the milk dripping assembly 5 includes a milk dispersion box 51 , a filter 53 and a cloth flow cover 52 . The top of the milk dispersion box 51 is provided with an inlet 54 connected to the milk introduction pipe joint 8 for introducing milk into the milk dispersion box 51 .

[0021] The filter 53 is placed in the milk dispersion box 51 to filter and disperse the milk. The cloth flow cover 52 is placed at the bottom of the milk dispersion box 51 to seal it. In this embodiment, the cloth flow cover 52 and the milk dispersion box 51 are connected by threads, making it easy to assemble and disassemble. The cloth flow cover 52 is provided with milk drip holes 55 at intervals. The milk drip holes 55 allow the milk to drip downward in a dispersed manner, increasing the contact surface between each drop of milk and the rising steam, rapidly heating it, and completing ultra-high temperature instantaneous sterilization. This helps shorten the heating time and maximize the preservation of the milk's active substances.

[0022] like Figure 1 As shown, the steam injection pipe 4 is vertically arranged in the high-temperature sterilizer 1 and symmetrically distributed on both sides below the milk dripping assembly 5.

The edges of the first flow distribution plate 11 and the second flow distribution plate 12 are welded and fixed to the inner wall of the rapid cooling box 2 to prevent leakage.

[0025] Several cooling guide tubes 10 are arranged between the first distribution plate 11 and the second distribution plate 12. In this embodiment, the first distribution plate 11 and the second distribution plate 12 are provided with distribution holes connected to the cooling guide tubes 10, so that the milk after ultra-high temperature instantaneous sterilization can flow downward into the milk junction box 3 through the cooling guide tubes 10.

[0026] A water inlet pipe joint 15 connected to the cold water chamber is provided on one side of the rapid cooling box 2, and a water outlet pipe joint 16 connected to the cold water chamber is provided on the other side of the rapid cooling box 2. The water inlet pipe joint 15 and the water outlet pipe joint 16 are externally connected to a cooling water circulation machine to circulate cooling water into the cold water chamber to cool the cooling guide pipe 10, thereby accelerating the cooling of the milk in the cooling guide pipe 10. Moreover, the number of cooling guide pipes 10 is large, the milk flow rate distributed to each cooling guide pipe 10 is small, and the cooling speed is fast, which is conducive to retaining the original flavor and active substances of the milk.

[0027] like Figure 1 As shown, a second cover plate 13 is provided at the bottom of the milk junction box 3, and a milk outlet pipe joint 14 is provided at the bottom of the second cover plate 13.
