[0036] Reference Figure 4 As shown, the top surface of the pull rod 281 is horizontally fixed with a sliding block 28, which is made of POM (polyoxymethylene) engineering plastic to provide good self-lubricating performance and reduce sliding friction, thereby improving the service life; one end of the sliding block 28 is horizontally fixed with a screw hole seat 282, which is internally provided with a threaded hole of M6 specification and is threadedly matched and connected with the screw rod 25 to realize the sliding adjusting function.

[0037] Reference Figure 4 As shown, the top of the adjusting cylinder 21 is vertically and symmetrically fixed with a sliding strip 24, which is made of 6061 aluminum alloy and has high strength and corrosion resistance; one side of the sliding strip 24 is vertically rotatably connected with a screw rod 25, which has a diameter of Φ8 mm and a pitch of 1.5 mm to ensure high accuracy during the adjusting process and adapt to different flow adjusting requirements.

[0039] Reference Figure 4As shown, the end face of the plurality of lifting columns 261 is vertically fixed with a threaded stud 262, which is made of SUS304 stainless steel material and is treated with nitriding to improve the thread strength and wear resistance; the other end face of the plurality of lifting columns 261 is vertically provided with a screw groove 263, the depth of which is set to 6mm, which is threadedly matched with the threaded stud 262 to ensure the connection stability and avoid loosening phenomenon caused by fluid impact or long-term use; the adjacent threaded studs 262 and screw grooves 263 of the plurality of lifting columns 261 are threadedly assembled to ensure the close combination of the overall structure and prevent displacement of the lifting part 26 during use; the top threaded stud 262 of the plurality of lifting columns 261 is threadedly assembled on the bottom surface of the threaded hole plate 27 to ensure the stability of the overall structure and ensure that the through hole can be accurately aligned with the milk inlet pipe 22 and the milk outlet pipe 23, thereby realizing precise flow control.

[0040] Reference Figure 4 As shown, the outer wall of the plurality of lifting columns 261 is fixedly provided with a sealing gasket 264 made of high-temperature-resistant silicone material, which can maintain good sealing performance in a working environment of up to 150°C; the thickness of the sealing gasket 264 is set to 2mm to ensure close contact with the inner wall of the adjusting cylinder 21 and prevent fluid leakage, while providing good shock resistance to reduce vibration and noise that may occur during operation.

[0041] Example 2: Colostrum pasteurization machine flow regulation experiment based on adjustable flow

[0042] In this embodiment, the precise control of colostrum flow is realized by the lifting structure of the adjusting part to adapt to different sterilization methods and improve the uniformity of sterilization. The equipment materials used in this embodiment include an adjusting cylinder made of SUS304 food-grade stainless steel, the height of which is set to 300mm, the inner diameter is Φ50mm, and the outer wall thickness is 3mm to ensure the structural stability and stability of fluid flow.

[0043] The lifting part includes a plurality of lifting columns, each of which has a height of 30mm and is made of food-grade high-strength POM (polyoxymethylene) material to reduce the frictional resistance during fluid flow. The through hole diameters of each lifting column are set to Φ18mm, Φ15mm, Φ12mm and Φ10mm respectively to ensure precise matching of different colostrum flow requirements. During the experiment, by adjusting the screw rod to rotate 1 turn, the sliding block moves down 2mm along the sliding bar, so that the through hole of the lifting column gradually matches the milk inlet pipe and the milk outlet pipe, thereby realizing flow regulation.

[0044] In the experiment, the colostrum was divided into three groups, the first group used Φ18mm through hole, the colostrum flow was 2.5L / min; the second group used Φ12mm through hole, the colostrum flow was reduced to 1.5L / min; the third group used Φ10mm through hole, the flow was further reduced to 1.0L / min. The experimental results showed that with the decrease of the inner diameter of the through hole, the residence time of the colostrum in the body of the pasteurizer increased, which made the sterilization more thorough, the sterilization efficiency increased by 15%, ensured the uniformity of sterilization, and reduced the loss rate of active ingredients.

[0045] Comparative case: the traditional colostrum pasteurizer adopts fixed flow mode, and in the experiment, the same colostrum is used for pasteurization, and the flow cannot be accurately controlled, which leads to that in high-temperature short-time sterilization, part of the colostrum cannot reach enough sterilization time due to too fast flow speed, and the sterilization effect decreases by about 20%; while in low-temperature long-time sterilization, part of the colostrum is over-heated due to too slow flow speed, leading to an increase of 12% in the loss rate of nutritional ingredients. Through comparison, it is shown that the adjustable flow mechanism in the embodiment effectively improves the sterilization quality and the retention rate of nutrients.

[0046] Embodiment 3: Precise sliding adjustment experiment based on screw adjustment mechanism

[0047] In this embodiment, the sliding block is precisely controlled by the screw adjustment mechanism to ensure that the lifting piece can realize stable flow adjustment. The experimental device includes sliding block, sliding bar, screw rod, screw hole seat and other components, among which the sliding block is made of POM material with a thickness of 5mm and excellent wear resistance; the sliding bar is made of 6061 aluminum alloy with a length of 200mm to ensure the stability of sliding adjustment; the screw rod is made of Φ8mm 304 stainless steel screw rod with a pitch of 1.5mm, and the sliding block moves down 1.5mm per rotation, realizing precise height control.

[0048] During the experiment, the sliding block was adjusted to adjust the through hole of the lifting column from Φ18mm to Φ10mm, and the flow change and sterilization effect were recorded after each adjustment. The experimental results showed that after each adjustment, the colostrum flow could be reduced according to the set proportion, and in the high-temperature short-time sterilization (75℃, 15s) and low-temperature long-time sterilization (63℃, 30min) modes, the sterilization uniformity was improved to 98%, and the retention rate of nutritional ingredients was increased by 10%.

[0049] Comparative case: the traditional adjustment mode adopts a manual plug-in structure, which cannot accurately control the height of the sliding block, resulting in a flow deviation of up to 20% after each adjustment. For example, when the flow needs to be adjusted to 1.5L / min, the flow floating range of the traditional device is 1.2L / min-1.8L / min, while the flow deviation of the screw adjustment mechanism in this embodiment is controlled within ±0.1L / min, which significantly improves the adjustment accuracy and the stability of the device.

[0050] Example 4: Colostrum flow stability optimization experiment based on sealing structure

[0051] In this embodiment, the stability of colostrum flow is improved by fixing the sealing pad 264 on the outer wall of the pull column, and the problem of fluid leakage that may occur during the sterilization process is reduced. The sealing pad 264 is made of high-temperature resistant silicone material, with a thickness of 2mm, installed on the outer wall of the pull column, ensuring that it can still maintain good sealing performance in a high-temperature and high-humidity environment.

[0052] The experimental device was operated in a 63℃ environment for 120 minutes, and the stability of the colostrum flow was monitored by a flow sensor. The experimental results show that the use of the sealing pad effectively prevents fluid leakage, and the colostrum flow remains within a floating range of ±0.05L / min for 120 minutes. Compared with the case without installing the sealing pad, the flow fluctuation is reduced by 50%, improving the consistency of the sterilization process.

[0053] Comparative case: The traditional device does not use a sealing pad, resulting in fluid leakage during the adjustment process. The experimental results show that under the same operating conditions, the device without a sealing pad has a cumulative flow loss of 150mL within 120 minutes, accounting for 3% of the total processing capacity, while the device of this embodiment has a flow loss of only 30mL, accounting for less than 0.6%. This proves the effectiveness and necessity of the sealing structure.

[0054] Example 5: Durability test of food-grade stainless steel material

[0055] This embodiment uses SUS304 food-grade stainless steel for key components such as the adjustment cylinder, colostrum inlet pipe, and colostrum outlet pipe, and conducts corrosion resistance and cleanliness tests. The experimental conditions simulate the long-term use environment of the pasteurization equipment, with the adjustment piece immersed in a solution containing 2% lactic acid, with a temperature setting of 45℃, and continuous immersion for 48 hours to evaluate its corrosion resistance.

[0056] The experimental results show that the SUS304 stainless steel material does not have oxidation spots and corrosion marks under the experimental conditions, with a 70% reduction in corrosion rate compared to ordinary 201 stainless steel, and the adhesion rate of surface residues is reduced to 0.02g / cm 2 , with a 40% increase in cleaning efficiency.

[0057] Comparative case: The traditional device uses ordinary 201 stainless steel, and in the same immersion experiment, after 48 hours, there are slight corrosion spots on the surface, and there are still obvious residues after cleaning, which can easily accumulate pollutants during long-term use. The SUS304 stainless steel material of this embodiment effectively solves this problem, improving the durability and food safety of the device.

[0058] The working principle of the utility model is as follows: when using, according to the colostrum sterilization flow demand, the threaded rotation screw hole cover 29 is split from the inner thread 211 at the top of the adjusting cylinder 21, the sliding block 28 is pushed out on the slide bar 24 by rotating the screw rod 25, the screw hole plate 27 is pulled out from the adjusting cylinder 21, a plurality of pull columns 261 with different hole diameters in the adjusting part 2 are sequentially arranged below the screw hole plate 27 according to the order of the hole diameter of the through hole of the plurality of pull columns 261 sequentially reducing from top to bottom, then the adjacent threaded column 262 of the plurality of pull columns 261 is assembled together with the screw groove 263, at the same time, the threaded column 262 at the top of the plurality of pull columns 261 is assembled on the bottom surface of the screw hole plate 27, after the pre-installation is completed, the plurality of pull columns 261 are inserted into the adjusting cylinder 21, the threaded installation of the screw hole cover 29 is good, and the sliding block 28 is slidingly inserted on the slide bar 24, the colostrum inlet pipe 22 and the colostrum outlet pipe 23 on both sides of the adjusting cylinder 21 are respectively communicated with the colostrum outlet pipe and the milk inlet 11 of the pasteurizer body 1, according to the colostrum sterilization flow demand, the threaded driving screw hole seat 282 at one end of the sliding block 28 is driven by rotating the screw rod 25, the sliding block 28 is vertically moved down on the slide bar, the through hole of different sizes on different pull columns 261 is adjusted to be on the same horizontal line with the colostrum inlet pipe 22 and the colostrum outlet pipe 23, the colostrum flows into the pasteurizer body 1, the colostrum flow into the pasteurizer body 1 is controlled by the different hole diameters of the plurality of pull columns 261, the demand of controlling the colostrum flow is met, different sterilization modes are applicable, and the uniform colostrum sterilization effect is ensured.

[0059] The above only is the preferred implementation manner of the utility model, it should be pointed out that, for ordinary technical personnel in the prior art, on the premise of not departing from the principle of the utility model, still can make a number of improvements and refinements, these improvements and refinements also should be regarded as the protection range of the utility model.
