Description

Technical Field

[0001] This utility model belongs to the technical field of dairy production equipment, and in particular relates to a dairy membrane concentration device. Background Technology

[0002] Dairy membrane concentration technology utilizes the selective permeation properties of ultrafiltration membranes to separate large molecules (such as proteins and fats) from small molecules (such as water and lactose) in dairy products under pressure. This technology is widely used in whey protein concentration, cheese production, and dairy product standardization, offering advantages such as low operating temperature, high nutrient retention, and low energy consumption. However, the susceptibility of ultrafiltration membranes to fouling during concentration has become a key bottleneck restricting its efficiency and cost in industrial applications.

[0003] Existing technologies that rely on the natural flow of cleaning fluid to wash the membrane surface suffer from insufficient pressure, making it difficult to penetrate the contaminants adsorbed inside the membrane pores. They can only wash away loosely attached contaminants (such as free protein particles) on the membrane surface, failing to penetrate the adsorbed gel layer or biofilm inside the pores. This leads to accelerated membrane performance degradation and a shortened lifespan. To address these issues, it is essential to design a dairy product membrane concentration device. Utility Model Content

[0004] This invention provides a dairy product membrane concentration device to solve the above-mentioned problems in the prior art.

[0005] This utility model is implemented as follows: a dairy product membrane concentration device includes a container, a sealing cap is provided at the upper end of the container, the sealing cap is connected to the container by screws, a first pipe is connected and fixedly installed at the upper end of the sealing cap, a second pipe is connected and fixedly installed at the bottom of the container, and the first pipe and the second pipe are connected to a dairy product circulation pipe.

[0006] The container has a first annular ring fixedly installed inside, and an ultrafiltration membrane is fixedly connected inside the first annular ring. The container also has a second annular ring, which is rotatably installed at the bottom of the first annular ring. Multiple plates arranged in a circular array are fixedly installed on the second annular ring. The container also has a circular plate that can slide up and down, and multiple openings are made on the circular plate. The lower end of the plate is inserted into the opening and seals the opening. The container has a driving mechanism for moving and rotating the circular plate up and down. The container also has a liquid injection mechanism for injecting water into the container cavity above the circular plate.

[0007] As a preferred embodiment, flanges are fixedly installed at the ends of both the first and second pipes.

[0008] As a preferred embodiment, the lower end of the container is configured as a funnel shape, and the upper end of the sealing cap is configured as an inverted funnel shape.

[0009] As a preferred embodiment, the liquid injection mechanism includes a branch pipe, which is connected to and fixedly installed on the upper part of the outer side of the container. A valve is installed on the branch pipe, and a suction pump is fixedly installed at the end of the branch pipe.

[0012] As a preferred embodiment, the container is equipped with an observation window.

[0013] Compared with related technologies, the dairy product membrane concentration device provided by this utility model has the following beneficial effects:

[0014] The device uses an electric telescopic rod to push the circular plate upward, compressing the space above the plate inside the container. Under mechanical pressure, the cleaning fluid is forced to flow backward through the ultrafiltration membrane (i.e., from the permeate side of the membrane to the feed side). This pressurized backwashing can more effectively remove large molecules (such as proteins and fats) adsorbed inside the membrane pores and on the membrane surface, significantly improving cleaning efficiency compared to conventional gravity washing.

[0015] When the device is not in use, the circular plate is moved upward by an electric telescopic rod, and the lower end of the plate is inserted into the opening. Then, a servo motor drives the circular plate to rotate, which can drive multiple plates to rotate. During the rotation, one end of each plate can scrape off the emulsion adhering to the inner wall of the container. Attached Figure Description

[0023] A preferred embodiment of the dairy membrane concentration apparatus provided by this utility model is, for example... Figures 1 to 4 As shown:

[0024] A dairy product membrane concentration device includes a container 1, with a sealing cap 2 at the upper end of the container 1. The sealing cap 2 is connected to the container 1 by screws. A first pipe 3 is connected to and fixedly installed at the upper end of the sealing cap 2, and a second pipe 4 is connected to and fixedly installed at the bottom of the container 1. The first pipe 3 and the second pipe 4 are connected to a dairy product circulation pipe. A first annular ring 5 is fixedly installed inside the container 1, and an ultrafiltration membrane 6 is fixedly connected inside the first annular ring 5. A second annular ring 10 is provided inside the container 1 and is rotatably installed at the bottom of the first annular ring 5. Multiple plates 11 arranged in a circumferential array are fixedly installed on the second annular ring 10. A circular plate 12 that can slide up and down is provided inside the container 1. Multiple through holes 13 are opened on the circular plate 12. The lower ends of the plates 11 are inserted into the through holes 13 and the through holes 13 are sealed. A driving mechanism is provided inside the container 1 to drive the circular plate 12 to move up and down and rotate. A liquid injection mechanism is installed on the container 1 to inject water into the inner cavity of the container 1 above the circular plate 12. Flanges are fixedly installed at both ends of the first pipe 3 and the second pipe 4. The lower end of the container 1 is funnel-shaped, and the upper end of the sealing cap 2 is inverted funnel-shaped.

[0025] The injection mechanism includes a branch pipe 7, which is connected to and fixedly installed on the upper outer side of the container 1. A valve 8 is installed on the branch pipe 7, and a suction pump 9 is fixedly installed at the end of the branch pipe 7. The discharge pipe of the suction pump 9 is connected to the branch pipe 7, and the inlet pipe of the suction pump 9 is connected to the external cleaning fluid. A guide section 14 is fixedly installed on the top of the circular plate 12, and the guide section 14 is conical. The drive mechanism includes a support plate 15, which is located inside the container 1 and fixedly connected to the container 1. An electric telescopic rod 16 is fixedly installed on the support plate 15, and a servo motor 17 is fixedly installed at the output end of the electric telescopic rod 16. The output shaft of the servo motor 17 is fixedly connected to the center of the bottom of the circular plate 12. An observation window is installed on the container 1. During the upward movement of the circular plate 12, the lower end of the plate 11 is inserted into the through-hole 13 and seals the through-hole 13.

[0026] In this embodiment, dairy raw materials enter the inner cavity of container 1 through the top first pipe 3 and flow downwards under the action of gravity or external pressure, passing through the ultrafiltration membrane 6 fixed on the first annular ring 5. The ultrafiltration membrane 6 retains large molecules (such as proteins and fats) to achieve concentration; while small molecules (such as water and lactose) and part of the permeate pass through the membrane into the lower part of container 1.

[0027] The electric telescopic rod 16 drives the servo motor 17 and the circular plate 12 to move upwards, inserting the lower end of the plate 11 into the perforation 13 and sealing the perforation 13. Then, the suction pump 9 injects the cleaning solution into the injection container 1, positioned above the circular plate 12. This fills the space between the circular plate 12 and the ultrafiltration membrane 6 with cleaning solution. As the circular plate 12 continues to move upwards, the cleaning solution is pressurized and passes through the ultrafiltration membrane 6 in reverse.

[0028] When the circular plate 12 is pushed upward by the electric telescopic rod 16, the space above the circular plate 12 in the container 1 is compressed, and the cleaning fluid is forced to flow backward through the ultrafiltration membrane 6 under mechanical pressure (i.e., from the permeate side of the membrane to the feed side). This pressurized backwashing can more effectively remove large molecules (such as proteins and fats) adsorbed in the membrane pores and on the membrane surface, and the cleaning efficiency is significantly improved compared to conventional gravity washing.

[0029] When the device is idle, the electric telescopic rod 16 drives the circular plate 12 to move upward, and the lower end of the plate 11 is inserted into the through hole 13. Then, the servo motor 17 drives the circular plate 12 to rotate, and the circular plate 12 can drive multiple plates 11 to rotate. During the rotation, one end of the plate 11 can scrape off the emulsion adhering to the inner wall of the container 1.
