Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dairy product production, in particular to a raw milk production line. Background Art
[0002] During the raw milk production process, only factories with fat standardization can solve the problem of fat floating. For factories with fat-free standardization, the fat content of raw milk from different batches and different origins is different, and the resulting dairy products have a certain degree of fat floating phenomenon. Utility Model Content
[0003] In view of this, the utility model provides a raw milk production line to solve the problem of fat floating in the currently prepared dairy products.
[0004] The utility model provides a raw milk production line, comprising a feeding device, a particle size detection device, a homogenizer and a controller; the feeding device is used to provide raw milk; the particle size detection device is arranged downstream of the feeding device and is used to detect the particle size of the raw milk; the homogenizer is arranged downstream of the particle size detection device and is used to homogenize the raw milk, and the working parameters of the homogenizer during homogenization are determined according to the particle size of the raw milk.
[0005] On the basis of the existing production line, the utility model adds a particle size detection device between the feeding device and the homogenizer. The particle size detection device can detect the particle size of the raw milk in the production line. Therefore, the working parameters of the homogenizer during the homogenization process, such as the homogenization pressure, can be adjusted according to the particle size of the raw milk, so that the particle size of the finished product can be controlled, thereby solving the problem of fat floating.
[0006] In an optional embodiment, the raw milk production line further includes a preheating device, which is disposed between the feeding device and the particle size detection device and is used to heat the raw milk.
[0007] This allows the raw milk to be preheated so that it reaches the sterilization temperature.
[0008] In an optional embodiment, the raw milk production line further includes a variable diameter channel, a first end of the variable diameter channel is connected to the feeding device or the preheating device, and a second end is connected to the particle size detection device, wherein the caliber of the first end is larger than the caliber of the second end.
[0009] This is because, in order to ensure the accuracy of the detection results in the particle size detection device, the pipe diameter of the particle size detection device needs to be within a certain range (for example, about 25 mm). Under normal circumstances, the pipe diameter of the raw milk production line is relatively thick (for example, about 63 mm), so a variable diameter channel is set upstream of the particle size detection device.
[0010] In an optional embodiment, the particle size detection device includes a detection channel and a detection probe; the detection channel is connected to the second end of the variable diameter channel at one end and is connected to the homogenizer at the other end; the detection probe is arranged in the detection channel and is used to detect the particle size of the raw milk.
[0011] This enables online detection of raw milk particle size.
[0012] In an optional embodiment, the detection probe is made of sapphire.
[0013] This is because the raw milk production line is a high-temperature, high-acid and high-alkali environment. In order to ensure the service life of the particle size detection device, the detection probe is made of sapphire.
[0014] In an optional embodiment, the particle size detection device further includes a stainless steel shell, which is arranged on the periphery of the detection channel.
[0015] This can extend the service life of the particle size detection device.
[0016] In an optional embodiment, the raw milk production line further includes a detection device, which is disposed between the feeding device and the preheating device and is used to detect the fat content, protein content and total solid content in the raw milk.
[0017] In this way, the fat content of the raw milk can be accurately detected, so that the controller can determine the working parameters of the homogenizer when homogenizing the raw milk according to the particle size and fat content of the raw milk.
[0018] In an optional embodiment, the raw milk production line further includes a sterilization device, which is arranged downstream of the homogenizer and is used to sterilize the raw milk.
[0019] This allows the raw milk to be sterilized.
[0020] In an optional embodiment, the raw milk production line further includes a heat exchange device, which is disposed downstream of the sterilization device and is used to perform heat exchange treatment on the raw milk.
[0021] This can lower the temperature of the sterilized product so that the product temperature meets the storage requirements.
[0022] In an optional embodiment, the raw milk production line further includes a storage device, which is disposed downstream of the heat exchange device and is used to store the raw milk.
[0023] This allows the sterilized product to be stored. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0029] Fat buoyancy is related to the particle size of raw milk. Milk is a biochemical fluid with colloidal properties. Milk fat is dispersed in the form of milk fat globules within the emulsion, forming an oil-in-water emulsion system. The milk fat content is generally 3-5%. Milk fat globules typically range in diameter from 0.1 to 22 nm, with those around 3 nm being the most common. Each milliliter of milk contains approximately 2 to 4 billion milk fat globules. During storage, these globules undergo irregular Brownian motion. When two or more milk fat globules collide due to thermal motion, they penetrate each other at their hydration membranes. Once these membranes are broken, the globules fuse, resulting in a globule merger. The larger the resulting globule (i.e., the larger its particle size), the lower its specific gravity, and the faster it floats. Therefore, milk rich in large milk fat globules makes it easier to separate cream. When the diameter of a milk fat globule approaches 1 nm, it rarely floats.
[0030] Based on this, according to an embodiment of the present utility model, a raw milk production line is provided, including a feeding device, a particle size detection device, and a homogenizer; the feeding device is used to provide raw milk; the particle size detection device is arranged downstream of the feeding device, and is used to detect the particle size of the raw milk; the homogenizer is arranged downstream of the particle size detection device, and is used to homogenize the raw milk, wherein the working parameters of the homogenizer during homogenization are determined according to the particle size of the raw milk.
[0031] Based on the existing production line, this utility model adds a particle size detection device between the feeding device and the homogenizer. The particle size detection device can detect the particle size of the raw milk in the production line. Therefore, the working parameters of the homogenizer during the homogenization process, such as the homogenization pressure, can be adjusted according to the particle size of the raw milk, so that the particle size of the finished product can be controlled, thereby solving the problem of fat floating. Table 1 Relationship between raw milk fat, particle size and homogenization pressure
[0032]
[0033]
[0034] For example, Table 1 shows the relationship between raw milk fat, particle size and homogenization pressure. As can be seen from Table 1, different fat content and different homogenization pressure will result in different product particle sizes. The lower the raw milk fat content and the same homogenization pressure, the lower the product particle size will be, and the less likely the fat will float. Specifically, (1) When the fat content is 3.4-3.6, when the homogenization pressure is 200 bar, the finished product particle size is in the range of 0.45-0.5; when the homogenization pressure is 220 bar, the finished product particle size is in the range of 0.2-0.3; (2) When the fat content is 3.6-3.8, when the homogenization pressure is 200 bar, the finished product particle size is in the range of 1.2-1.5; when the homogenization pressure is 220 bar, the finished product particle size is in the range of 0.6-0.9. (3) Fat belongs to 3.9-4.1. When the homogenization pressure is 200 bar, the particle size of the finished product is in the range of 1.5-1.8; when the homogenization pressure is 220 bar, the particle size of the finished product is in the range of 1.3-1.4; (4) Fat belongs to 4.2-4.4. When the homogenization pressure is 200 bar, the particle size of the finished product is in the range of 2.5-2.6; when the homogenization pressure is 220 bar, the particle size of the finished product is in the range of 2.1-2.4.
[0035] Based on this, the working parameters of the homogenizer during homogenization can be obtained by the following method: obtain the current fat content of the raw milk, obtain the current particle size of the raw milk, and obtain the corresponding relationship between the preset fat content, particle size and homogenization pressure; use the current fat content and current particle size to search the corresponding relationship between the fat content, particle size and homogenization pressure to obtain the current homogenization pressure of the homogenizer.
[0036] For example, the data in Table 1 can be input into a controller. The controller receives the measured particle size and fat content and adjusts the homogenization pressure based on these data. The controller is housed in a stainless steel box (30x30x18cm, 7kg) and allows calibration and operation of the particle size analyzer via a touch panel. The controller can be mounted on a panel, platform, or even on the homogenizer.
[0037] The controller can be configured to communicate with 1 or 2 NiSoMates, one of which can be installed at the homogenizer inlet to provide early warning to the operator / customer’s central control PLC to make necessary adjustments and achieve the correct product quality.
[0038] It should be noted that the above only gives one method for determining the working parameters of the homogenizer during homogenization processing, but the determination of the working parameters of the homogenizer during homogenization processing is not limited to the above method. Other methods can also be used. For example, after obtaining the particle size of the raw milk according to the detection results of the particle size detection device, the staff adjusts the working parameters of the homogenizer during homogenization processing according to the particle size of the raw milk.
[0039] In an optional embodiment, the raw milk production line further includes a preheating device, which is disposed between the feeding device and the particle size detection device, and heats the raw milk. Thus, the raw milk can be preheated to reach a sterilization temperature.
[0040] In an optional embodiment, the raw milk production line further includes a variable diameter channel, wherein a first end of the variable diameter channel is connected to the feeding device or the preheating device, and a second end of the variable diameter channel is connected to the particle size detection device, wherein the caliber of the first end is larger than the caliber of the second end. In other words, the variable diameter channel serves as a transition pipe connecting the thick tube and the thin tube.
[0041] This is because, in order to ensure the accuracy of the detection results in the particle size detection device, the pipe diameter of the particle size detection device needs to be within a certain range (for example, about 25 mm). Under normal circumstances, the pipe diameter of the raw milk production line is relatively thick (for example, about 63 mm), so a variable diameter channel is set upstream of the particle size detection device.
[0042] In an optional embodiment, the particle size detection device includes a detection channel and a detection probe; one end of the detection channel is connected to the second end of the variable diameter channel, and the other end is connected to the homogenizer; the detection probe is arranged in the detection channel and is used to detect the particle size of the raw milk.
[0043] This enables online detection of raw milk particle size.
[0044] In an optional embodiment, the detection probe is made of sapphire.
[0045] This is because the raw milk production line is a high-temperature, high-acid and high-alkali environment. In order to ensure the service life of the particle size detection device, the detection probe is made of sapphire.
[0046] In an optional embodiment, the particle size detection device further comprises a stainless steel housing, which is disposed on the periphery of the detection channel, thereby extending the service life of the particle size detection device.
[0047] In an optional embodiment, the raw milk production line further includes a sterilization device, which is disposed downstream of the homogenizer and is used to sterilize the raw milk. Specifically, the sterilization device can be pasteurized.
[0048] This allows the raw milk to be sterilized.
[0049] In an optional embodiment, the raw milk production line further includes a heat exchange device, which is disposed downstream of the sterilization device and is used to perform heat exchange treatment on the raw milk.
[0050] In an optional embodiment, the raw milk production line further includes a storage device, which is disposed downstream of the heat exchange device and is used to store the raw milk.
[0051] For example, Figure 1 This is a schematic diagram of an example of a raw milk production line of the present invention. Figure 2 This is a structural diagram of an example of the raw milk production line of the utility model. Figure 1 and Figure 2 As shown, the raw milk production line includes a feeding device 4, a detection device 7, a preheating device 2, a particle size detection device 5, a homogenizer 3, a sterilization device 1, a heat exchange device 6 and a storage device 8 which are connected in sequence.
[0052] Among them, the feeding device 4 is used to provide raw milk; the detection device 7 is used to detect the fat content, protein content and total solid content in the raw milk; the preheating device 2 is used to preheat the raw milk to reach the sterilization temperature; the particle size detection device 5 is used to detect the particle size of the raw milk; the homogenizer 3 is used to homogenize the raw milk; the sterilization device 1 is used to sterilize the raw milk; the heat exchange device 6 is used to perform heat exchange treatment on the raw milk; and the storage device 8 is used to store the finished product obtained after sterilization.
[0053] In the raw milk production line, the raw milk passes through the feeding device 4, the detection device 7, the preheating device 2, the particle size detection device 5, the homogenizer 3, the sterilization device 1, and the heat exchange device 6 in sequence, and finally enters the storage device 8.
