Description

Technical Field

[0001] This utility model relates to the field of milk processing equipment technology, and in particular to a continuous milk delactose and desalting membrane separation device. Background Technology

[0002] Dairy products are an important part of daily diet. To meet the needs of different consumer groups, the milk processing industry needs to carry out various refined processes on raw milk. Among them, delactose removal and desalting are key processes in the production of functional milk, and membrane separation technology is the mainstream technical means to achieve these processes.

[0003] Existing milk delactose and desalting equipment has certain limitations in its implementation. Many devices use intermittent or batch processing methods, which require adding a certain batch of raw milk to the equipment, completing the entire processing flow, and then discharging the finished product before proceeding to the next batch. This process results in discontinuous production, low overall production efficiency, and requires a lot of manual intervention, making it difficult to meet the needs of modern large-scale industrial production.

[0004] Furthermore, in some technical solutions, steps such as lactose removal, desalting, and subsequent fine filtration often require the combination of multiple independent, single-function devices. For example, milk needs to pass through a lactose removal membrane device first, then be pumped into another desalting membrane device, and finally may need to enter an independent fine filtration system. This separate equipment layout not only occupies a large area and increases the complexity of pipeline connections, but also increases the overall equipment investment cost and subsequent maintenance cost.

[0005] Therefore, this invention proposes a continuous milk delactose and desalting membrane separation device to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing technology, the continuous milk delactose and desalting membrane separation equipment is mostly intermittent, resulting in low production efficiency, and the functions of delactose removal, desalting, and fine filtration need to be completed by multiple separate devices, resulting in high equipment investment costs. The present invention aims to provide a continuous milk delactose and desalting membrane separation equipment with an improved structure that can integrate multiple membrane separation functions and realize continuous operation.

[0007] This utility model provides a continuous milk delactose and desalting membrane separation device, including: a pretreatment multi-membrane separation mechanism, which includes a raw material tank, a first connecting pipe, a filter, a second connecting pipe, and a preheater.

These three membrane assemblies are highly integrated in structure. The primary lactose-removing membrane assembly, the secondary desalting membrane assembly, and the tertiary fine filtration membrane assembly are connected in series in the fluid path. One end of the feed pipe is fixedly connected to the preheater, and the other end is connected to the feed port of the primary lactose-removing membrane assembly, so that the preheated material can smoothly enter the membrane separation stage. The discharge port of the tertiary fine filtration membrane assembly is fixedly connected to a discharge pipe for discharging the final finely filtered material.

[0009] Preferably, the continuous milk lactose desalting membrane separation equipment further includes a product collection mechanism, which includes a buffer tank, a sterilizer, and a finished product tank. The end of the discharge pipe away from the three-stage fine filtration membrane assembly is fixedly connected to the buffer tank. The buffer tank is connected to the sterilizer through a third connecting pipe, and the sterilizer is connected to the finished product tank through a fourth connecting pipe, thus forming a complete finished product collection and post-processing flow path.

[0010] Preferably, a material pump is fixedly installed on the second connecting pipe, the third connecting pipe and the fourth connecting pipe, and the material pump provides power for the continuous flow of material in the entire equipment pipeline.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0034] As a preferred embodiment, to prevent the raw milk from settling in the raw material tank 101, please refer to... Figure 2 Inside the raw material tank 101, a stirrer 4 is rotatably connected. The drive shaft of the stirrer 4 passes through the top of the raw material tank 101 and is connected to an external drive motor.

[0035] As another preferred embodiment, to facilitate real-time monitoring of the milk level in the finished product tank 203 by operators, please refer to... Figure 1 and Figure 4 A level gauge 3 is fixedly installed on the outer wall of the finished product tank 203.

[0037] As another preferred embodiment, in order to promptly discharge the waste generated during the membrane separation process, please refer to... Figure 3 A waste discharge pipe 6 is also provided inside the separation box 106. The bottom waste outlets of the primary lactose desulping membrane assembly 108, the secondary desalination membrane assembly 109 and the tertiary fine filtration membrane assembly 1010 are all connected to or fixedly installed in the waste discharge pipe 6. One end of the waste discharge pipe 6 passes through the side wall of the separation box 106 and extends to the outside of the separation box 106.

[0038] As another preferred embodiment, for easier cleaning of impurities trapped in filter 102, please refer to... Figure 1 A waste discharge pipe 7 is fixedly installed on the filter 102, and the waste discharge pipe 7 is connected to the slag discharge port of the filter 102.

[0039] The working principle of this continuous milk lactose removal and desalting membrane separation device is as follows:

[0040] When milk needs to be processed, the raw milk is first injected into the raw material tank 101, and the agitator 4 installed in the raw material tank 101 is started to stir it to prevent the milk from settling. Then, the valve on the pipeline is opened and the feed pump 5 on the second connecting pipe 105 is started. Under the action of power, the raw milk enters the filter 102 through the first connecting pipe 104. The filter 102 intercepts impurities in the milk. If too many impurities accumulate in the filter 102, it can be cleaned through the discharge pipe 7. The filtered milk is transported to the preheater 103 through the second connecting pipe 105. The preheater 103 preheats the milk to a suitable temperature range for membrane separation. The preheated milk enters the membrane module in the separation box 106 through the feed pipe 1011. During this process, the pressure regulating valve 8 on the feed pipe 1011 adjusts the feed pressure to ensure the stability of the membrane separation process.

[0041] Subsequently, the milk flows sequentially through a primary lactose-removing membrane assembly 108, a secondary desalting membrane assembly 109, and a tertiary fine filtration membrane assembly 1010, which are connected in series on the mounting rack 107. In the primary lactose-removing membrane assembly 108, the lactose in the milk is separated. Then, it enters the secondary desalting membrane assembly 109 for desalting treatment, and finally enters the tertiary fine filtration membrane assembly 1010 to complete fine filtration. The waste generated during this membrane separation process is discharged to the outside of the separation tank 106 through the waste discharge pipe 6 connected at the bottom. After three stages of treatment, the finely filtered milk is discharged into the buffer tank 201 through the discharge pipe 1012 for temporary storage and buffering.

[0042] Finally, the feed pump 5 on the third connecting pipe 204 is started to transport the milk in the buffer tank 201 to the sterilizer 202 for pasteurization. After sterilization, the finished milk is transported to the finished product tank 203 for storage by the feed pump 5 on the fourth connecting pipe 205. At this time, the finished product collection status can be observed in real time through the level gauge 3 on the finished product tank 203. The whole process, through the cooperation of each connecting pipe and the feed pump 5, realizes continuous and automated operation from raw material pretreatment, multi-stage membrane separation to finished product collection, effectively improving production efficiency and ensuring product quality.
