Description

Technical Field

[0001] This utility model relates to the field of milk production technology, and in particular to a concentration membrane device for milk production and purification. Background Technology

[0002] In the milk concentration industry, membrane concentration equipment is widely used due to its high efficiency and energy saving. However, existing membrane concentration equipment has significant drawbacks: on the one hand, traditional concentration membranes are easily adsorbed and adhered to the membrane surface by substances such as proteins, fats, and lactose when processing milk, forming a stubborn fouling layer that greatly reduces the concentration efficiency and lifespan of the membrane; on the other hand, existing cleaning methods mostly rely on manual chemical rinsing, which is not only time-consuming and costly, but also leaves chemical residues that may affect the quality of subsequent milk products. Furthermore, frequent use of chemicals can cause irreversible damage to the membrane material. In addition, traditional equipment lacks effective structural design, making it difficult to achieve rapid concentration and unable to remove contaminants in a timely manner during operation, thus failing to meet the high-efficiency, environmentally friendly, and safe production requirements of the dairy industry. Therefore, there is an urgent need for a new type of milk concentration membrane equipment that can quickly achieve concentration, avoiding prolonged concentration time and the resulting material and membrane contamination problems. This new milk concentration membrane equipment should also solve the problems of membrane fouling and cleaning. Utility Model Content

It also includes at least one set of concentration membrane modules. Preferably, three sets of concentration membrane modules are provided: a primary concentration membrane module 6, a secondary concentration membrane module 601, and a tertiary concentration membrane module 602.

That is, the input end of the primary concentration membrane module 6 is connected to the output end of the material tank 1, and the input end of the secondary concentration membrane module 601 is connected to the output end of the primary concentration membrane module 6. The input end of the third-stage concentration membrane 602 is connected to the output end of the second-stage concentration membrane module 601 to achieve multi-stage concentration. The feed end of the concentration membrane module is connected to the output end of the feeder. A concentration pipe 703 is fixedly installed at the concentrate outlet of the concentration membrane module. The top of the material tank 1 is connected to the concentration pipe 703 through the first connecting pipe 102, and a second valve 104 and a seventh valve 704 are fixedly installed on the first connecting pipe 102 and the concentration pipe 703, respectively. The bottom of the cleaning liquid tank 2 is connected to the drain pipe 201, which stores cleaning liquid. The drain pipe 201 is connected to the input end of the feeder through the third valve 203. Furthermore, the top of the cleaning liquid tank 2 is connected to the concentrate pipe 703 via a second connecting pipe 202 equipped with a fourth valve 204. During concentration: the material in the material tank 1 is fed into the primary concentration membrane module 6 through the feeding device. After one concentration, the concentrate enters the secondary concentration membrane module 601 for further concentration, achieving a second concentration. The concentrate then enters the tertiary concentration membrane module 602 for further concentration and is finally discharged from the concentrate pipe 703 for subsequent use. Alternatively, it can enter the material tank 1 through the first connecting pipe 102 and then be circulated and concentrated according to the above operation to further improve the concentration quality. During cleaning: after concentration is completed, the cleaning liquid is discharged through the feeding device and the drain pipe 201. The cleaning solution in the cleaning solution tank 2 is pumped to the primary concentration membrane module 6, the secondary concentration membrane module 601, and the tertiary concentration membrane module 602. At this time, the second valve 104, the fourth valve 204, and the permeate outlet of the concentration membrane module are all closed, and the seventh valve 704 is open. At this time, the cleaning solution can clean the inner wall of the pipeline and the concentration membrane in the concentration membrane module. After multiple rinsings, clean water is poured into the cleaning solution tank 2. Finally, the inner wall of the pipeline and the surface of the concentration membrane are cleaned with clean water according to the above cleaning method to clean off the residual cleaning solution. Then, the permeate outlet of the concentration membrane module is opened and cleaned with clean water.

[0026] In use, by connecting the output end of the cleaning fluid tank 2 to the feeding device, and then connecting the feed end of the concentration membrane module to the feeding device, it is convenient to clean the inner wall of the pipeline and the surface of the concentration membrane after concentration, reducing manual operation and helping to improve the effect of use.

[0027] Reference Figure 1 The feed end of the primary concentration membrane module 6 is connected to the output end of the feeder via the primary circulation pump 5. The concentrate outlets of the primary concentration membrane module 6, the secondary concentration membrane module 601, and the tertiary concentration membrane module 602 are respectively fixedly connected to a primary outlet pipe 7, a secondary outlet pipe 701, and a tertiary outlet pipe 702. The tertiary outlet pipe 702 is connected to the concentrate pipe 703, facilitating the delivery of the tertiary concentrated beef into the concentrate pipe 703 for subsequent use. Furthermore, the feed end of the secondary concentration membrane module 601 is connected to the primary outlet pipe 7 via the secondary circulation pump 501, and the feed end of the tertiary concentration membrane module is connected to... The three-stage circulation pump 502 is connected to the two-stage outlet pipe 701.

The temperature is maintained at 30-50℃. During use, the pressure of the liquid during concentration can be guaranteed by the first-stage circulation pump 502, the second-stage circulation pump 501, and the third-stage circulation pump 702, which facilitates concentration.

[0028] Reference Figure 1 and Figure 2 Here, the feeding components include a feeding pump 3. One end of the feeding pump 3 is connected to the input end of the primary circulation pump 5 through a filter element 4. The filter element 4 is a bag filter, preferably made of food-grade materials such as polypropylene (PP) or nylon, with the model number FD-2D-2S. A feed pipe 101 with a first valve 103 is fixedly installed at the bottom of the material tank 1, and an inlet pipe 301 with a fifth valve 303 is fixedly installed at the other end of the feeding pump 3. The feed pipe 101 and the inlet pipe 301 are connected, and the drain pipe 201 is connected to the inlet pipe 301.
