Description

Technical Field

[0001] This utility model relates to the field of dairy processing technology, specifically a defatting and separation device for dairy production. Background Technology

[0002] In dairy processing, defatting is one of the core processes. Its purpose is to separate the fat (milk fat) in whole milk from that in skim milk to obtain products with different fat contents (such as cream, butter, and skim milk).

[0003] Defatting separation is mainly based on centrifugation, which utilizes the difference in sedimentation velocity between fat globules (lower density) and skim milk (higher density) under centrifugal force. For centrifugation, disc centrifuges are commonly used, which generate strong centrifugal force (up to 10,000 times the force of gravity) through high-speed rotation (5,000–10,000 RPM).

[0004] After the milk enters the separator, it flows along the disc assembly. The fat globules, due to their lower density, move towards the central axis to form a layer of light cream.

[0005] Skim milk, due to its high density, flows along the outer edge of the disc and is discharged from the outer peripheral outlet.

[0006] Adjusting the flow rate and rotation speed can control the fat content (e.g., adjusting the fat content of light cream to 30-40% or the fat content of skim milk to <0.5%).

[0007] For existing disc centrifuges, when dairy products are input, they are directly transferred into the centrifuge chamber along the input channel. There is a problem in this process: the raw materials need to be pre-filtered to remove some impurities, such as grass clippings, hair, feed particles, mud and sand. The existing method is to pre-treat them through an external filtration device, which will affect the efficiency of defatting and separation.

[0008] In response, this technical solution designs a defatting and separation device for dairy product production. Utility Model Content

[0009] The purpose of this invention is to provide a defatting and separation device for dairy product production to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A defatting and separation device for dairy product production includes a main motor, a housing, a feed pipe, a rotating drum, and a disc assembly. The main motor, rotating drum, and disc assembly are all located inside the housing. The rotating drum serves as the core of high-speed rotation, and the disc assembly is installed on the rotating drum. The disc assembly is configured with multi-layered conical discs to increase the separation area and shorten the settling distance. The main motor is connected to the bottom of the rotating drum to drive it to rotate at high speed. A connecting cylinder is provided in the middle of the rotating drum, and the feed pipe is located inside the connecting cylinder to input the dairy products to be defatted and separated. The feed pipe and the connecting cylinder are connected in a sealed rotary manner. The feed pipe is stationary, while the connecting cylinder rotates around the feed pipe under the control of the rotating drum. The bottom of the feed pipe is connected to a discharge channel around the lower side of the rotating drum. The input dairy products are transferred to the disc assembly by the discharge channel, and then the high-speed rotation of the disc assembly centrifuges the dairy products to defatting, forming heavy phase defatted milk and light phase fat globules.

[0012] Located on the outer edge of the disc assembly, there is a heavy phase output channel that connects upwards. The top of the heavy phase output channel connects outwards to a heavy phase outlet for discharging skim milk. A light phase output channel is provided on one side of the upper surface of each disc in the disc assembly. The top of the light phase output channels are connected to a vertical rising channel. The top of the rising channel connects outwards to a light phase outlet for discharging fat globules. That is, the fat globules move along the upper side of the disc towards the center and are discharged from the light phase outlet.

[0013] Skim milk flows outwards along the space between the upper disc and the inner wall of the casing → and is discharged from the heavy phase outlet;

[0014] Meanwhile, a multi-stage filter assembly is installed inside the feed pipe for pre-filtering the dairy products to be transferred into the drum. The multi-stage filter assembly is detachably connected to the feed pipe, which facilitates quick installation and separation as needed (filtering required, filter cleaning, replacement, etc.).

[0015] Compared with the prior art, the beneficial effects of this utility model are: by integrating multi-stage filtration and centrifugal separation functions, the external pre-filtration step is eliminated, thereby improving production efficiency.

[0016] With its multi-stage filter mesh pore size gradient distribution, it can adapt to raw milk with different impurity contents, resulting in better filtration.

[0017] The filter components feature a plug-in design, allowing for quick assembly and disassembly without tools, making them easy to clean or replace. Attached Figure Description

[0026] Please see Figures 1-3A defatting and separation device for dairy product production includes a main motor 10, a housing 11, a feed pipe 12, a rotating drum 15, and a disc assembly 17. The main motor 10, rotating drum 15, and disc assembly 17 are all housed inside the housing 11. The rotating drum 15 serves as the core for high-speed rotation. The disc assembly 17 is mounted on the rotating drum 15 and consists of multi-layered conical discs to increase the separation area and shorten the settling distance. The main motor 10 is connected to the bottom of the rotating drum 15 to drive it to rotate at high speed. A connecting cylinder 22 is located in the center of the rotating drum 15, and the feed pipe... The feed pipe 12 is located inside the connecting cylinder 22 and is used to input the dairy products to be degreased and separated. The feed pipe 12 and the connecting cylinder 22 are sealed and rotated. The feed pipe 12 is stationary. Under the control of the drum 15, the connecting cylinder 22 rotates around the feed pipe 12. The bottom of the feed pipe 12 is connected to the discharge channel 16 on all sides facing the lower side of the drum 15. The input dairy products are transferred to the disc group 17 under the transmission of the discharge channel 16. Then, the high-speed rotation of the disc group 17 is used to degrease the dairy products, forming heavy phase defatted milk and light phase fat globules.

[0027] A heavy phase output channel 18 is connected upwards from the outer edge of the disc assembly 17. The top of the heavy phase output channel 18 is connected outwards to a heavy phase outlet 14 for outputting skim milk. A light phase output channel 19 is provided on one side of the upper surface of the discs of the disc assembly 17. The top of the light phase output channels 19 are connected to a vertical rising channel 20. The top of the rising channel 20 is connected outwards to a light phase outlet 13 for discharging fat globules. That is, the fat globules move along the upper side of the disc towards the center and are discharged from the light phase outlet 13.

[0028] Skim milk flows outward between the upper disc and the inner wall of the housing 11 → and is discharged from the heavy phase outlet 14;

[0029] Meanwhile, a multi-stage filter assembly is plugged into the feed pipe 12 to pre-filter the dairy products to be transferred to the drum 15. The multi-stage filter assembly is detachably connected to the feed pipe 12, which facilitates quick installation and separation as needed (whether filtration is required, cleaning or replacement of the filter screen, etc.).

[0030] The multi-stage filtration assembly includes longitudinally parallel filter screens 26 fixed by mounting columns 29. The pore sizes of the filter screens 26 decrease sequentially from top to bottom. A V-shaped inlet 30 is connected to the top of the mounting column 29. An extension ring plate 31 is installed on the top edge of the V-shaped inlet 30. The extension ring plate 31 is supported on the outside of the top of the feed pipe 12. The mounting column 29, together with the filter screens 26, extends into the feed pipe 12. The dairy products to be fed diffuse into the feed pipe 12 along the V-shaped inlet 30, and then pass through the filter screens 26 sequentially for initial filtration treatment, realizing the integrated operation mode of this defatting separation device and filtration.

[0031] In this embodiment of the invention, a plurality of locking pins 32 are installed at equal intervals in a ring at the bottom of the extension ring plate 31, and a locking hole 33 is opened at the top of the feed pipe 12 corresponding to the extension ring plate 31. The locking pins 32 are inserted into the locking hole 33 to position the extension ring plate 31.

[0032] It should be noted that the connection and operation between the main motor 10, housing 11, drum 15, disc assembly 17, light phase outlet 13, and heavy phase outlet 14 for the degreasing and separation of dairy products are based on existing conventional technology. This technical content is only a brief introduction to it; for detailed information, please refer to existing technology.

[0033] In one embodiment of the present invention, the tops of the heavy phase output channel 18 and the rising channel 20 are respectively connected to the heavy phase outlet 14 and the light phase outlet 13 via connecting ring caps 23. Due to the rotation of the disc group 17, the light phase outlet 13 and the heavy phase outlet 14 are stationary. At this time, the connecting ring caps 23 are used to perform a rotational connection function. That is, a T-shaped slip ring 24 is installed on one side of the bottom of the connecting ring cap 23. A T-shaped groove 25 is opened on the outer side of the top of the housing 11 corresponding to the T-shaped slip ring 24. The T-shaped slip ring 24 is rotated and connected in a limited manner along the inside of the T-shaped groove 25. The vertical cross-section of the T-shaped slip ring 24 and the T-shaped groove 25 is set as a T-shaped structure for longitudinal limiting.

[0034] Heavy phase outlet 14 and light phase outlet 13 are respectively connected to a point on the top of the connecting ring cap 23.

[0035] In a preferred embodiment of the present invention, a longitudinal limiting ring is installed on the outer wall of the feed pipe 12, and a rotating ring groove is opened in the inner wall of the connecting cylinder 22 corresponding to the longitudinal fiber ring. The longitudinal limiting ring rotates along the rotating ring groove to ensure that the feed pipe 12 is stationary relative to the connecting cylinder 22, and that the connecting cylinder 22 rotates normally.

[0036] The connection between the filter screen 26 and the mounting post 29 can be achieved in various ways, such as one-time welding positioning or detachable connection.

[0037] Detachable connections, such as those using bolts and curved clamps.

[0038] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control.

[0039] Feeding and filtration: Dairy products enter the feed pipe 12 through the V-shaped feed inlet 30 and pass through the multi-stage filter screen 26 layer by layer to remove physical impurities.

[0040] Centrifugal separation: The filtered dairy products are evenly distributed to the disc assembly 17 through the feeding channel 16. Under the high-speed rotation (5000–10000 RPM) of the drum 15, the fat globules (light phase) move towards the center and are discharged through the light phase outlet 13, while the skim milk (heavy phase) is discharged along the outer edge of the disc through the heavy phase outlet 14.

[0041] Dynamic sealing: The feed pipe 12 and the rotating connecting cylinder 22 achieve static and dynamic sealing through the longitudinal limiting ring and the rotating ring groove; the light / heavy phase outlet and the rotating component maintain a sealed rotating connection through the cooperation of the T-shaped slip ring 24 and the T-shaped slip groove 25.

[0042] Maintenance operation: When the filter screen needs to be cleaned or replaced, pull the extension ring plate upward to disengage the locking pin 32 from the locking hole 33, and the multi-stage filter assembly can be removed.

[0043] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0044] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
