The equipment can realize the concentration of birch sap efficiently through the cooperation of multistage pump and concentration element, has the characteristics of high degree of automation, stable operation. Feed pump 14, booster pump 15, circulating pump 20 and membrane concentration element 25 are communicated in series in proper order. This connection mode ensures that the liquid pressure is gradually increased, makes the separation effect of membrane concentration element 25 optimal, reduces the pressure loss of liquid in the pipeline simultaneously. The concentrated liquid outlet of membrane concentration element 25 is communicated with the liquid inlet of circulating tank 1 through the pipeline. The connection realizes the circulation of concentrated liquid, helps concentrated liquid to reach higher concentration, reduces raw material waste simultaneously.

[0028] The filtrate outlet of membrane concentration element 25 is communicated with the liquid inlet of cleaning tank 6 through the pipeline. The guidance of filtrate into cleaning tank 6 not only is convenient for collection, but also provides a reflux path for the subsequent cleaning process, improves the cleaning efficiency of the system. The liquid outlet of circulating tank 1 is communicated with the liquid inlet of feed pump 14 through raw liquid valve 4. Raw liquid valve 4 is used to adjust the flow entering feed pump 14, guarantees the liquid inlet stability of pump, thereby improves the overall concentration efficiency. The liquid outlet of cleaning tank 6 is communicated with the liquid inlet of feed pump 14 through cleaning valve 9. This connection mode is convenient for the delivery of cleaning liquid in cleaning tank 6, effectively realizes online cleaning operation, saves maintenance time. Heat exchanger 27 is arranged on the liquid inlet pipeline of membrane concentration element 25 and is used to adjust the inlet temperature. The accurate control of temperature can optimize the filtration performance of membrane, reduces the risk of fouling on the surface of membrane, improves the system operation stability.

[0029] The temperature table 12, temperature sensor 13, pre-membrane pressure gauge 22, pressure sensor 21, post-membrane pressure gauge sensor 23, post-membrane pressure gauge 24, concentrated liquid flow meter 16, and filtrate flow meter 29 are also included. The arrangement of these measuring devices enables real-time monitoring of system operating parameters, providing a guarantee for the safe and efficient operation of the system. The temperature table 12, temperature sensor 13, pre-membrane pressure gauge 22, and pressure sensor 21 are arranged on the pipeline on the liquid inlet side of the membrane concentration element 25. These monitoring points ensure that the inlet liquid temperature and pressure remain within the optimal operating range of the membrane concentration element 25, thereby improving the concentration effect. The post-membrane pressure gauge 24, post-membrane pressure gauge sensor 23, and concentrated liquid flow meter 16 are arranged on the pipeline on the concentrated liquid outlet side of the membrane concentration element 25. These devices monitor the pressure and flow data of the concentrated liquid outlet, allowing for timely detection and resolution of potential problems during the concentration process. The filtrate flow meter 29 is arranged on the pipeline on the filtrate outlet side of the membrane concentration element 25. This flow meter accurately measures the filtrate flow, providing reliable data support for the collection and reflux adjustment of the filtrate.

[0030] The control input ends of the feed pump 14, booster pump 15, and circulation pump 20 are electrically connected to the control output end of the control cabinet. The control cabinet centrally manages the operating status of all pumps, optimizes system operation logic, and achieves efficient concentration operations. The pipeline between the liquid outlet of the circulation tank 1 and the liquid inlet of the feed pump 14 is provided with a raw liquid valve 4. The raw liquid valve 4 controls the output flow of the liquid in the circulation tank 1, ensuring the stability and continuity of the concentration operation. The pipeline between the concentrated liquid outlet of the membrane concentration element 25 and the liquid inlet of the circulation tank 1 is provided with an adjusting valve 17 and a concentrated liquid reflux valve 5. The configuration of these valves allows for flexible adjustment of the concentrated liquid reflux, further improving the efficiency and quality of the concentration process. The pipeline between the concentrated liquid outlet of the membrane concentration element 25 and the liquid inlet of the circulation pump 20 is provided with an internal circulation valve 19. The internal circulation valve 19 allows the concentrated liquid to flow internally, thereby reducing the concentration time and improving equipment utilization. The liquid inlet of the cleaning tank 6 is connected to the concentrated liquid outlet of the membrane concentration element 25 through a cleaning concentrated liquid reflux valve 10. This design ensures that the cleaning liquid flows through the concentrated liquid pipeline during cleaning operations, providing thorough cleaning and extending the service life of the equipment. The filtrate outlet of the membrane concentration element 25 is connected to the cleaning tank 6 through a cleaning filtrate reflux valve 31.

[0031] The cleaning filtrate reflux valve 31 allows the cleaning liquid to flow through the filtrate pipeline, thoroughly cleaning all pathways in the system and preventing cross-contamination. The outlet of the cleaning tank 6 is connected to the blowdown pipeline and is equipped with a blowdown valve two 8. The blowdown valve two 8 provides an efficient discharge path for waste liquid during the cleaning process, simplifying operations and reducing human involvement. The filtrate outlet of the membrane concentration element 25 is connected to the filtrate pipeline through the filtrate production valve 30. The filtrate production valve 30 is used to accurately control the discharge or reflux of filtrate, ensuring efficient use of filtrate. A control valve two 32 is provided in the filtrate pipeline to adjust the discharge and reflux state of the filtrate. The adjustment function of the control valve two 32 enhances the flexibility of the system, which can adapt to different concentration requirements and process requirements. The main pipeline is connected to the main pipeline blowdown valve 26 through the blowdown pipeline. The main pipeline blowdown valve 26 realizes the centralized discharge of waste liquid in the system, which is convenient for maintenance and environmental protection, so as to realize the unified blowdown control in the system. The circulating tank 1 is equipped with a blowdown valve one 3 to discharge liquid. The circulating tank 1 is equipped with a liquid level transmitter one 2 to monitor the liquid level inside the circulating tank 1, and the cleaning tank 6 is equipped with a liquid level transmitter two 7 to monitor the liquid level inside the cleaning tank 6. The filtrate production valve 30 is used in conjunction with the control valve one 28 and the control valve two 32 to adjust the flow, discharge and reflux state of the filtrate.

[0032] Working principle: The birch sap membrane concentration system takes the circulating tank 1 as the core, and realizes the efficient concentration and automatic operation of birch sap through the cooperation of multiple components. When the system starts to work, the original liquid in the circulating tank 1 is first sent to the booster pump 15 by the feed pump 14, and then enters the membrane concentration element 25 after the pressure is raised. The membrane concentration element 25 utilizes the separation characteristics of its roll-shaped columnar multi-layer composite membrane to selectively separate the original liquid. During the separation process, the molecular weight cut-off of the filter membrane is 100-150 Dalton, which ensures the concentration of effective substances and the efficient separation of filtrate.

[0033] In the membrane concentration element 25, the birch sap is divided into two parts: concentrated liquid and filtrate. The concentrated liquid is transported to the circulating tank 1 through the concentrated liquid outlet for circulation treatment, so as to gradually increase the concentration and meet the concentration requirements. The filtrate flows out from the filtrate outlet and can be selected to be directly recycled or refluxed to the system after being measured by the filtrate flow meter 29, which is used for subsequent cleaning process. The concentrated liquid flow meter 16 on the concentrated liquid outlet side monitors the concentration effect in real time, while sensors such as the pre-membrane pressure gauge 22 and the post-membrane pressure gauge one 24 ensure that the system always operates within the optimal pressure range, thereby maintaining efficient separation.

[0034] During system operation, the heat exchanger 27 adjusts the temperature of the raw liquid to ensure that the liquid temperature is maintained within the optimal working range of the filter membrane, 5-45℃, which improves the filtering performance and avoids damage to the membrane element caused by high temperatures. In addition, the pressure sensor 21 and the temperature sensor 13 monitor the liquid parameters in real time, providing key data support for stable system operation. The control cabinet optimizes the operation logic of the system by centrally managing the feed pump 14, the booster pump 15, and the circulating pump 20, making the concentration process efficient and automated.

[0035] During the cleaning process, the cleaning tank 6 injects cleaning liquid into the membrane concentration element 25 through the circulating pump 20, and the cleaning liquid flows through the concentrated liquid outlet and the filtrate outlet to clean the membrane element and related pipelines. The backflow valves of the concentrated liquid outlet and the filtrate outlet guide the cleaning liquid back to the cleaning tank 6, ensuring the recycling of the cleaning liquid. Through the cooperation of the concentrated liquid cleaning valve 18 and the filtrate cleaning valve, residual substances inside the system can be completely removed.

[0036] The operation of the entire concentration system is precisely controlled and efficiently operated through the cooperation of various liquid level sensors, flow meters, and valves. The setting of the total pipeline blowdown valve 26 facilitates the centralized discharge of waste liquid, while the check valve 11 prevents fluid backflow, ensuring system safety. Finally, the white birch juice is concentrated to the target concentration, and the filtrate is fully recovered, thereby maximizing resource utilization and improving production efficiency.

[0037] Finally, it should be noted that the above-described preferred embodiments of the present application are not intended to limit the present application, and although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
