[0028] Combine the following Figure 1-Figure 3 The utility model describes a chocolate milk production line.

[0029] like Figure 1 As shown, the chocolate milk production line includes a raw milk processing system, a chocolate dissolving system, a mixing tank 50 and a tank to be filled 70. The mixing tank 50 has a first feed port, a second feed port and a discharge port. The raw milk processing system is connected to the first feed port. A filter 47 is provided on the connecting pipeline between the chocolate dissolving system and the second feed port. The discharge port is connected to the feed port of the tank to be filled 70. Figure 2 and Figure 3 As shown, the can 70 to be filled includes a can body 71, a stirring shaft 72 and a stirring paddle 73, wherein the stirring shaft 72 is installed in the can body 71, and the stirring paddle 73 is installed at the end of the stirring shaft 72. The stirring shaft 72 is inclined relative to the horizontal plane, and the vertical plane where the stirring shaft 72 is located is eccentrically arranged relative to the central axis of the can body 71. The filter 47 has multiple filter screens arranged in sequence along the flow direction of the fluid, and the mesh number of the filter screen is not less than 60 meshes.

[0030] The transport vehicle 10 transports the raw milk to the production plant, and the raw milk processing system is used to separate, filter and / or store the raw milk. In one embodiment, the raw milk processing system and the chocolate dissolving system are independent of each other, and the chocolate dissolving system is used to melt chocolate and cocoa powder into chocolate syrup, and then mix it evenly with the milk discharged from the raw milk processing system in the mixing tank 50. In another embodiment, part of the milk discharged from the raw milk processing system enters the chocolate dissolving system, and the chocolate dissolving system mixes this part of the milk with chocolate and cocoa powder into chocolate syrup, and then mixes it with other milk discharged from the raw milk processing system in the mixing tank 50.

[0031] The mixing tank 50 mixes milk, chocolate and cocoa powder. Specifically, the mixing tank 50 includes a barrel and a stirring wheel, and the stirring wheel is rotatably installed in the barrel. The barrel is provided with a first feed port, a second feed port and a discharge port, and the first feed port is connected to the discharge port of the raw milk processing system so as to transport milk into the mixing tank 50. The second feed port is connected to the discharge port of the chocolate dissolving system so as to transport chocolate slurry into the mixing tank 50. The stirring wheel rotates to fully mix the chocolate slurry with the milk, and then before filling, the chocolate milk is mixed with the aid of the waiting tank 70, and then filled and produced, so as to fully ensure the consistency of the filled product. Among them, the stirring wheel can be installed in the barrel in an inclined state, or can be arranged in the barrel in a vertical direction.

[0032] To be filled in can 70, in Figure 2 In the perspective shown, the central axis of the stirring shaft 72 forms an acute angle with the horizontal plane, so that the stirring shaft 72 is tilted in the tank body 71. Figure 3 In the perspective shown, the stirring shaft 72 extends vertically, and there is a gap between the vertical plane where the stirring shaft 72 is located and the central axis of the tank body 71, so that the stirring shaft 72 is eccentrically arranged. Therefore, when the stirring paddle 73 rotates to stir the fluid in the tank body 71, the flow dead zone in the tank body 71 can be effectively reduced, and the flow dead zone is controlled to be less than 0.5%, which effectively improves the uniformity of the mixing of the chocolate milk.

[0033] Specifically, the stirring paddle 73 rotates intermittently, and during stirring, the speed of the stirring paddle 73 is between 100 r / min and 500 r / min. For example, the stirring paddle 73 stirs for 2 min at an interval of 10 min. For another example, the stirring paddle 73 stirs for 4 min at an interval of 20 min. Of course, the stirring paddle 73 can also stir for any time between 10 min and 20 min, and for any time between 2 min and 4 min.

[0034] In order to prevent large chocolate particles from entering the mixing tank 50 and affecting the taste of the chocolate milk and the stratification effect after standing, the filter 47 is equipped with a plurality of filter screens arranged along the flow direction of the fluid in cooperation with the stirring shaft 72, and the mesh number of the filter screen is not less than 60 meshes.

[0035] For example, the filter 47 has two filter screens, wherein the mesh number of each filter screen is 140 or 100, etc. It is understandable that the mesh numbers of the two filter screens can be the same or different, as long as the mesh number of each filter screen is not less than 60.

[0036] like Figure 1 As shown, the chocolate milk production line further includes a filling system 80, which is connected to the tank 70 to be filled so as to fill the evenly stirred chocolate milk into the bottle.

[0037] In the chocolate milk production line provided by the embodiment of the utility model, the chocolate fluid first passes through the filter screen provided in the filter 47 to filter out large particles before entering the can 70 to be filled, and at the same time, the stirring shaft 72 is inclined and eccentrically arranged, which effectively reduces the stirring dead zone in the tank 71 and improves the uniformity of mixing. Therefore, before the chocolate milk mixed in the mixing tank 50 is filled, the chocolate milk is fully mixed by means of the filtration of the filter 47 and the stirring in the can 70 to be filled, ensuring that the layered height of the finished product after filling is consistent after standing, thereby ensuring the consistency of the product appearance and taste.

[0038] The normal angle between the central axis of the stirring shaft 72 and the horizontal plane is 15° to 45°.

[0039] The normal direction of the horizontal plane refers to the vertical direction, that is, the central axis of the tank body 71. Figure 2 As shown, the angle formed between the central axis of the stirring shaft 7220 and the normal of the horizontal plane is α, which is 15°, 20°, 45° or any angle between 15° and 45°. Compared with the traditional stirring shaft 72 vertically arranged in the tank body 71, the flow field generated by the rotation of the inclined stirring shaft 72 can effectively improve the mixing effect of the fluid inside the tank body 71.

[0040] Optional, such as Figure 3 As shown, there is a first distance H between the vertical plane where the stirring shaft 72 is located and the central axis of the tank body 71 . The first distance H is 15% to 25% of the diameter R of the tank body 71 .

[0041] The stirring shaft 72 is not arranged on the central symmetric plane of the tank body 71, but is arranged to one side of the tank body 71. Through the fluid stirring simulation test, it can be known that the eccentrically arranged stirring shaft 72 combined with the inclined setting can effectively reduce the flow dead zone area in the tank body 71, reduce the amount of unstirred fluid, and improve the stirring effect. For example, the first spacing is 15% of the diameter of the tank body 71. For another example, the first spacing H is 20% or 25% of the diameter R of the tank body 71. Of course, the first spacing H can also be the product of the diameter R of the tank body 71 and any value between 15% and 25%.

[0042] Specifically, Figure 1As shown, the raw milk processing system includes a raw milk separation device 20 and a temporary storage tank 30, wherein the feed port of the temporary storage tank 30 is connected to the raw milk separation device 20, and the discharge port of the temporary storage tank 30 is connected to the first feed port. The raw milk separation device 20 is used to separate the milk collected from the pasture to obtain milk with higher purity. The temporary storage tank 30 is used to store and preserve the raw milk processed by the raw milk separation device 20.

[0043] In one embodiment, the raw milk separation device 20 includes a centrifugal milk purifier, and the discharge port of the centrifugal milk purifier is connected to the first feed port. The centrifugal milk purifier filters and separates the raw milk, filters out the cow hair and tiny impurities therein, and obtains cow milk with high purity. In this embodiment, the raw milk processing system is only provided with a centrifugal milk purifier, and no degreasing operation is required. In another embodiment, the raw milk separation device 20 includes a centrifugal milk purifier and a fat separator, and the discharge port of the centrifugal milk purifier is connected to the feed port of the fat separator, and the discharge port of the fat separator is connected to the first feed port. In this embodiment, after the cow milk is impurities removed by the centrifugal milk purifier, it is degreased after passing through the fat separator to reduce the fat content in the chocolate milk.

[0044] Optional, such as Figure 1 As shown, the raw milk processing system has a first discharge port and a second discharge port, and the chocolate dissolving system includes a first heat exchanger 41, a chocolate shear tank 42 and a second heat exchanger 43. The first discharge port is connected to the first feed port, the second discharge port is connected to the feed port of the chocolate shear tank 42 through the first heat exchanger 41, and the discharge port of the chocolate shear tank 42 is connected to the second feed port through the second heat exchanger 43. For example, the first discharge port and the second discharge port are arranged on the temporary storage tank 30. For another example, the raw milk processing system only includes the raw milk separation device 20, and the temporary storage tank 30 is not arranged. In this case, the first discharge port and the second discharge port are both arranged on the raw milk separation device 20. In this embodiment, the milk separated by the raw milk separation device 20 does not need to be temporarily stored, but a part of it flows directly to the mixing tank 50, and the other part flows to the first heat exchanger 41.

[0045] Part of the milk discharged from the raw milk processing system flows to the mixing tank 50, and the other part enters the chocolate shear tank 42 after being heated by the first heat exchanger 41. The heated milk is mixed with chocolate blocks, chocolate particles or cocoa powder in the chocolate shear tank 42, and then enters the mixing tank 50 after being cooled by the second heat exchanger 43.

[0046] Optionally, the first heat exchanger 41 and the second heat exchanger 43 are both plate heat exchangers. Of course, the first heat exchanger 41 and the second heat exchanger 43 can also be other forms of heat exchange structures. The first heat exchanger 41 is used to heat the milk to melt the chocolate. The second heat exchanger 43 is used to cool the chocolate slurry to mix with the milk in the mixing tank 50.

[0047] like Figure 1 As shown, a first filter 44 and a first flow meter 45 are provided on the connecting pipeline between the first heat exchanger 41 and the chocolate shearing tank 42 ; and / or a filter 47 and a second flow meter 48 are provided on the connecting pipeline between the second heat exchanger 43 and the mixing tank 50 .

[0048] The first filter 44 is used to filter impurities in the milk, and the first flow meter 45 is used to monitor the amount of milk entering the chocolate shearing tank 42. The filter 47 can filter out the chocolate particles that are not fully melted in the chocolate slurry. The second flow meter 48 is used to monitor the flow of the chocolate slurry entering the mixing tank 50. When the filter 47 is blocked, the flow monitored by the second flow meter 48 will change. The user can monitor the abnormality of the filter 47 through the second flow meter 48 so as to deal with the blockage problem in time.

[0049] like Figure 1 As shown, a first valve body 46 is provided on the connecting pipeline between the first heat exchanger 41 and the chocolate shearing tank 42; a second valve body 49 is provided on the connecting pipeline between the second heat exchanger 43 and the mixing tank 50. By controlling the on and off of the first valve body 46 and the second valve body 49, the start and stop of the entire production line can be controlled, which facilitates the maintenance of various equipment in the production line.

[0050] In order to extend the shelf life and storage period of chocolate milk, a sterilization system 60 is provided between the mixing tank 50 and the tank to be filled 70 for sterilization before filling. Optionally, the sterilization system 60 uses a high temperature sterilizer, a pasteurizer or other sterilization equipment.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
