[0036] like Figure 1 As shown, the filling production system provided by the embodiment of the present invention includes a liquid mixing device 100, a powder mixing device 200, a total conveying device 300 and a first filling device 400. The liquid mixing device 100 includes a liquid mixing tank 110 which is sealed and uses nitrogen for backup pressure protection. The powder mixing device 200 includes a vacuum mixer 210. The outlet of the liquid mixing tank 110 and the outlet of the vacuum mixer 210 are both connected to the inlet of the total conveying device 300, and the outlet of the total conveying device 300 is connected to the first filling device 400.

[0037] In the filling production system of the embodiment of the present invention, the liquid material is mixed and transported by the liquid mixing device 100, and the powder material is mixed and transported by the powder mixing device 200. The outlets of the liquid mixing device 100 and the powder mixing device 200 are both connected to the main conveying device 300. The mixed liquid and powder enter the main conveying device 300 for transportation, and are further mixed in the main conveying device 300. Finally, the main conveying device 300 transports them to the first filling device 400 for filling. Compared with the prior art, sensitive and special function high value-added liquid materials and powder materials are uniformly mixed in a mixing tank before ultra-high temperature treatment. The present invention uses the liquid mixing device 100 and the powder mixing device 200 to mix the liquid material and the powder material separately, and can independently perform suitable mixing processing for different types of materials. Liquids and powders are prepared in different forms according to their characteristics, so as to improve the mixing and emulsification effect and reduce the operating cost as much as possible, and avoid the functional effect of the material being changed due to the unified preparation method.

[0038] Active liquid raw materials that are sensitive to heat and oxygen, as well as special functional high-added liquid raw materials, are mixed in a liquid mixing tank 110. The liquid mixing tank 110 uses a sealed and nitrogen-protected tank body. The liquid mixing tank 110 is always in a closed state during production and processing. The material is fed according to the production batch, which effectively prevents external gas from entering the mixing tank, and can reduce the gas content in the liquid material, reduce the oxidation reaction caused by excessive oxygen content, and reduce the adverse effect on the quality of the material. Active powder raw materials that are sensitive to heat and oxygen, as well as special functional high-added powder raw materials are mixed in a vacuum mixer 210. The vacuum mixer 210 works under negative pressure conditions. The oxygen content of the mixed materials is low, which can meet the requirements of powder raw material chemical processing. It solves the problem that the current production process pays little attention to oxygen-sensitive substances, the processing methods are limited, and the oxidation reaction is obvious, especially for fatty acids. After processing, the functional effect decreases and the flavor changes seriously.

[0039] The present invention provides a flexible processing system for adding heat-, oxygen-sensitive and special-functional substances at a constant concentration and with ultra-low loss, so as to solve the problems in the prior art of thermal denaturation or inactivation caused by thermal processing and reducing the influence of oxygen on oxygen-sensitive substances through nitrogen protection, and at the same time provide a better technical choice for the addition of various functional nutritional additives.

[0040] In this embodiment, the powder feed hopper 230 is used to feed the vacuum mixer 210 , and the fed powder raw materials are sucked into the vacuum mixer 210 for mixing by utilizing the negative pressure principle.

[0041] In this embodiment, the liquid mixing device 100 also includes a first twin-screw pump 120 and a liquid feeding hopper 130, through which the liquid feeding hopper 130 feeds the liquid into the liquid mixing tank 110. After the liquid material is mixed in the liquid mixing tank 110, it enters the main conveying device 300 through the liquid conveying line driven by the first twin-screw pump 120.

[0042] According to an embodiment provided by the present invention, the total conveying device 300 includes a main conveying line 390 formed by sequentially connecting a first valve body 310, a centrifugal separation device 320, a deep impurity removal and filtration device 330, and an absolute sterilization device 340, the outlet of the liquid mixing device 100 and the outlet of the powder mixing device 200 are both connected to the inlet of the centrifugal separation device 320 through the first valve body 310, and the first outlet of the absolute sterilization device 340 is connected to the first filling device 400. In this embodiment, the liquid material uniformly mixed by the liquid mixing device 100 and the powder material uniformly mixed by the powder mixing device 200 enter the total conveying device 300 through the first valve body 310, and after being processed by the centrifugal separation device 320, the deep impurity removal and filtration device 330, and the absolute sterilization device 340 in sequence along the conveying direction of the main conveying line 390, the material is finally sent to the first filling device 400 for filling.

[0043] Active materials that are sensitive to heat and oxygen, as well as special functional high-added materials, all need to be obtained through complex separation or extraction processes. In this process, due to the high technical difficulties and prominent technical bottlenecks of the separation or extraction process, it is difficult to achieve 100% pure raw materials, so the above raw materials may be mixed with other impurities. Even if the liquid or powder raw materials are processed in different ways, it is impossible to achieve completely uniform particle size of the materials, which will cause the absolute sterilization device 340 to be blocked during the absolute sterilization process, thereby affecting the production and operation efficiency and increasing the cost of replacing the filter element in the absolute sterilization device 340. In order to effectively solve the above problems and increase the permeability of the material through the absolute sterilization device 340, the present invention adopts a combination of a centrifugal separation device 320 and a deep impurity removal filter device 330 for pre-sterilization, thereby effectively improving the membrane permeability of the material and achieving a better sterilization effect.

[0044] Centrifugal separation and deep impurity removal filtration have different principles and different processing targets. The processing effect of single centrifugal separation is limited, and the continuous operation time of single deep impurity removal filtration is limited. The present invention combines the centrifugal separation device 320 and the deep impurity removal filtration device 330 to process the materials on the main conveying line 390, effectively extending the operating time of the deep impurity removal filtration and the absolute sterilization filter element, and improving production efficiency.

[0045] In the production process of the prior art, more than two absolute sterilization devices 340 need to be configured according to the amount of material to be processed, and the filter shells include 5-inch, 10-inch, 20-inch and 30-inch specifications. Among them, the 5-inch filter shell has a small specification and low material loss, but the amount of processed materials is limited. Therefore, the production line of the prior art often uses filter elements of 20 inches and above, and the single shell material loss is large. In the present invention, the material pre-treated by the centrifugal separation device 320 and the deep impurity removal filter device 330 enters the absolute sterilization device 340. The filter element in the absolute sterilization device 340 adopts a biological grade absolute sterilization filter element, and the material treated by it can reach commercial sterility.

[0046] In this embodiment, the total conveying device 300 further includes a third online detector 360, a first flow meter 370, and a second twin-screw pump 380. The third online detector 360 detects the concentration of the material entering the main conveying line 390, the first flow meter 370 detects the flow rate of the material conveyed by the main conveying line 390, and the second twin-screw pump 380 provides driving force for the conveying of the material in the main conveying line 390. Along the main conveying line 390, the third online detector 360, the first flow meter 370, the centrifugal separation device 320, the deep impurity removal filter device 330, the second twin-screw pump 380, and the absolute sterilization device 340 are sequentially connected.

[0047] According to an embodiment provided by the present invention, the filling production system further includes a recovery device 500, the second outlet of the absolute sterilization device 340 is connected to the inlet of the recovery device 500, and the inlet of the liquid mixing tank 110 is connected to the outlet of the recovery device 500. In this embodiment, a second outlet is provided at the top of the absolute sterilization device 340, and the second outlet is connected to the inlet of the liquid mixing tank 110 through the recovery device 500, that is, the material in the absolute sterilization device 340 can be returned to the liquid mixing tank 110 again through the second outlet and the recovery device 500, so as to circulate the material.

[0048] At the beginning of production, the filter element in the absolute sterilization device 340 is first moistened with pure water, and the material is passed after the pure water completely fills the filter housing, that is, the material top water is applied. At this time, the entire main conveying line 390 is filled with pure water. In order to ensure the constant concentration of the material, the mixed liquid part of the material and the pure water needs to be directly discharged through the second outlet of the absolute sterilization device 340 in the previous production process, so the material loss will be caused during the material top water process. In addition, after the production is completed, the absolute sterilization device 340 is still filled with materials, but at present, since the material concentration cannot be guaranteed to be constant after the production is completed, the materials retained in the absolute sterilization device 340 are not recovered but directly discharged, which will also cause a large amount of material loss. Due to the particularity of the materials, they are all high value-added materials, and their extraction process is complicated, difficult to obtain, high cost, and small amount of materials. Therefore, the present invention is effective in recycling by setting a recovery device 500, and reducing material loss is of great significance for cost saving and large-scale production.

[0049] It can be understood that the absolute sterilization device 340 has an inlet and a first outlet at the bottom and a second outlet at the top. During the process of pushing water through the material, the pure water filled in the filter housing and the material entering from the bottom inlet are gradually pushed out from bottom to top until the filter housing is completely filled with the material, and there is no pure water residue to affect the material concentration.

[0050] After high-intensity heat treatment, its function and sensory effects change significantly, seriously affecting consumers' nutritional needs and sensory experience.

[0051] According to an embodiment provided by the present invention, the recovery device 500 includes a second valve body 510 and a first online detector 520. The inlet of the first online detector 520 is connected to the second outlet of the absolute sterilization device 340 through the second valve body 510, and the outlet of the first online detector 520 is connected to the inlet of the liquid mixing tank 110. In this embodiment, the second valve body 510 and the first online detector 520 are sequentially arranged on the pipeline connecting the second outlet of the absolute sterilization device 340 and the inlet of the liquid mixing tank 110. The first online detector 520 is used to accurately determine whether the liquid flowing out of the absolute sterilization device 340 has materials. Ultraviolet detection can be used for the detection of protein materials to determine whether to start recovery. If recovery starts, the second valve body 510 is opened, otherwise the second valve body 510 is closed.

[0052] In the process of watering the material, the prior art usually uses human experience to judge whether there is only material but no pure water in the conveying pipeline of the recovery device 500. Therefore, material loss or material concentration fluctuation may occur during the watering process of the material. In order to effectively recover the material in the total conveying device 300 when the absolute sterilization device 340 is filled with materials and the production is terminated, direct discharge is changed to online recovery. Traditional processing mainly relies on manual judgment of concentration, which leads to fluctuations in product concentration. In order to ensure that the concentration of some products meets the indicated value, excessive addition is often used to ensure that the concentration meets the specified requirements, which also leads to increased production costs. Therefore, the present invention performs real-time detection through the first online detector 520 to ensure that the concentration of the additives in the material in the recovery device 500 is constant and reduce material loss in the recovery process.

[0053] According to an embodiment provided by the present invention, the total conveying device 300 further includes a third valve body 350, the outlet of the absolute sterilization device 340 is connected to the inlet of the first filling device 400 through the third valve body 350, and the third valve body 350 is connected to the second valve body 510 to form a secondary conveying line 3100. In this embodiment, the third valve body 350 is arranged on the pipeline connecting the absolute sterilization device 340 and the first filling device 400, and the third valve body 350 is also connected to the second valve body 510 to form the secondary conveying line 3100 of the total conveying device 300, and the material in the absolute sterilization device 340 is sent to the recovery device 500 through the secondary conveying line 3100 and returns to the liquid mixing tank 110 again.

[0054] In actual production, the distance between the absolute sterilization device 340 and the first filling device 400 is very long. Therefore, even if the material top-up work has been completed in the absolute sterilization device 340, the liquid in this section of the pipeline may contain pure water or the material concentration may not meet the standard, which will also affect the concentration of the material. Moreover, when the production is finished, the material in this section of the pipeline is often directly discharged to the ground at the third valve body 350, which will also cause material loss. The present invention designs a secondary conveying line 3100 at the third valve body 350 to send the material in the pipeline between the absolute sterilization device 340 and the first filling device 400 to the recovery device 500. When material recovery is required, the main conveying line 390 is connected to the recovery device 500 through the secondary conveying line 3100. When production is required, the main conveying line 390 is connected to the first filling device 400 to realize automatic switching between production and recovery.

[0055] During the material top water process, the third valve body 350 is first connected to the second valve body 510 through the auxiliary conveying line 3100, wherein the first online detector 520 is required to determine whether to start recycling as well as whether to start production. When there is low-concentration material, the recycling mode is started. When the material concentration is consistent with the target concentration, the third valve body 350 automatically switches to the production mode. Similarly, when the production is ended, the first online detector 520 determines to end recycling, and ends recycling when no material can be detected, thereby effectively improving the recycling efficiency.

[0056] According to an embodiment provided by the present invention, the recovery device 500 further includes a main recovery conveying line 570 formed by the fourth valve body 530, the membrane filtration device 540, the second online detector 550 and the fifth valve body 560 being connected in sequence, and an auxiliary recovery conveying line 580 formed by the fifth valve body 560 and the fourth valve body 530 being connected in sequence, the outlet of the first online detector 520 is connected to the inlet of the membrane filtration device 540 through the fifth valve body 560, and the outlet of the second online detector 550 is connected to the inlet of the liquid mixing tank 110 through the fifth valve body 560. In this embodiment, the membrane filtration device 540 and the second online detector 550 are connected in sequence to form the main recovery conveying line 570, the fourth valve body 530 and the fifth valve body 560 are designed at both ends of the main recovery conveying line 570, and the fourth valve body 530 and the fifth valve body 560 are independently connected through the auxiliary recovery conveying line 580, that is, the main recovery conveying line 570 and the auxiliary recovery conveying line 580 form a parallel pipeline. After the material passes the first online inspection, it can be divided into two paths at the fourth valve body 530. One path passes through the auxiliary recovery conveying line 580 and reaches the fifth valve body 560 to enter the liquid mixing tank 110. The other path passes through the main recovery conveying line 570 and enters the liquid mixing tank 110 through the fifth valve body 560.

[0057] Since the concentration of the recovered materials fluctuates, in order to ensure uniform concentration, a membrane filtration device 540 is configured on the main recovery conveying line 570 to concentrate the low-concentration materials to ensure the constant concentration of the final materials and avoid material concentration fluctuations caused in the actual production process. The type of membrane filtration is selected according to the molecular weight or particle size of the materials, such as ultrafiltration for protein materials, and reverse osmosis membrane concentration for flavors and fragrances. Reverse osmosis can also be selected, but reverse osmosis will reduce the concentration efficiency of protein materials.

[0058] The first online detector 520 at the front end of the membrane filter device 540 automatically determines whether membrane concentration is required. If concentration is not required, the recovered material directly enters the liquid mixing tank 110 through the fourth valve body 530, the auxiliary recovery conveying line 580 and the fifth valve body 560. If the material does not reach the target concentration, it needs to be concentrated through the membrane filter device 540. The material concentrated by the membrane filter device 540 needs to be further determined by the second online detector 550 at the rear end of the membrane filter device 540 whether it reaches the target concentration. If it reaches, it enters the liquid mixing tank 110 through the fifth valve body 560; if it does not reach, it passes through the fifth valve body 560, passes through the auxiliary recovery conveying line 580 again, returns to the fourth valve body 530, and enters the membrane filter device 540 again to continue concentration.

[0059] According to an embodiment provided by the present invention, the filling production system also includes a basic mixing device 600 and a second filling device 700. The basic mixing device 600 includes a basic mixing conveying line formed by a batching tank 610, a centrifugal pump 620, a sterilization device 630 and a static mixer 640 connected in sequence, and a branch pipeline 650. The outlet of the static mixer 640 is connected to the inlet of the second filling device 700, the pipeline connecting the sterilization device 630 and the static mixer 640 is connected to the outlet of the branch pipeline 650, and the inlet of the branch pipeline 650 is connected to the third valve body 350. In this embodiment, on the basis of the liquid mixing device 100, the powder mixing device 200, the recovery device 500, the main conveying device 300 and the first filling device 400, a basic mixing device 600, a second filling device 700 and a branch line 650 are further added. After the basic mixing device 600 mixes and batches the materials in the batching pipe through the batching tank 610, the materials are sent to the sterilization device 630 through the centrifugal pump 620 to kill the pathogenic bacteria, pathogenic bacteria and spores. After the product meets the commercial sterility requirements, the materials are sent to the second filling device 700. The branch line 650 connects the third valve body 350 with the front end of the static mixer 640. The materials mixed and sterilized in the main conveying device 300 are sent to the static mixing device through the branch line 650 together with the materials that have passed through the sterilization device 630 for mixing, and then the second filling device 700 fills and aseptically fills to the specified package type for delivery.

[0060] In this embodiment, in order to adapt to actual production needs, the material in the total conveying device 300 of the present application is mixed with the output material of the basic mixing device 600 in the conventional mixing process, and then filled and shipped out. Through different processing methods, the material and liquid mixing that meet commercial sterility requirements can be achieved, the production line pressure is shared, the product quality is improved, and it can adapt to the production line construction.

[0061] In one embodiment, the basic mixing device 600 further includes a second flow meter 660 . The second flow meter 660 is designed at the rear end of the sterilization system to detect the material flow of the entire basic mixing device 600 .

[0062] According to an embodiment provided by the present invention, the filling production system further includes a control device 800, which is connected to the second valve body 510, the third valve body 350, the fourth valve body 530 and the fifth valve body 560 respectively. In this embodiment, the second valve body 510, the third valve body 350, the fourth valve body 530 and the fifth valve body 560 can all adopt three-way reversing valves, and the control device 800 controls the opening and closing and reversing operations of each valve body through the results of detection by the first online detector 520 and the second online detector 550. The use of the online detection and online control system of the present invention can reduce the temporary storage tanks for materials, and at the same time, the physical and chemical data control is more accurate.

[0063] In this embodiment, the control device 800 includes a PLC control system 810 and an online control module 820 . The PLC control system 810 is connected to communicate with each valve body through the online control module 820 corresponding to each valve body.

[0064] According to an embodiment provided by the present invention, the powder mixing device 200 further includes a smoothing pump 220, and the outlet of the vacuum mixer 210 is connected to the inlet of the main conveying device 300 through the smoothing pump 220. In this embodiment, since the active powder raw materials sensitive to heat and oxygen, and the special functional high-added powder raw materials are small in quantity and high in cost, the mixing process in the vacuum mixer 210 is as gentle as possible to reduce the irreversible mechanical damage to the raw materials caused by strong shearing, but the powdering material is difficult, and there may be a risk of raw materials agglomerating due to low shearing, so a smoothing pump 220 is separately configured on the discharge pipeline to enhance the emulsification effect of the material and meet the subsequent processing requirements.

[0065] In this embodiment, the powder mixing device 200 also includes a sixth valve body 250 and a third twin-screw pump 240. The outlet of the vacuum mixer 210, the sixth valve body 250, the third twin-screw pump 240, the smooth pump 220 and the first valve body 310 are connected in sequence. At the same time, the sixth valve body 250 is also connected to the top feed port of the vacuum mixer 210. That is, the powder material sent out from the vacuum mixer 210 can be transported by two routes, one is to pass through the sixth valve body 250 and be sent out through the third twin-screw pump 240, and the other is to pass through the sixth valve body 250 and then return to the vacuum mixer 210 for recycling.

[0066] Due to the sensitivity of the above materials, twin-screw pumps are used for material transportation in the process to further reduce the loss caused by mechanical shearing.

[0067] According to an embodiment provided by the present invention, the first filling device 400 includes an aseptic bag filling machine. In this embodiment, due to the small amount of material and high cost, it is hoped to reduce material loss, and the direct backfill to the product needs to be as close to the filling machine as possible. However, due to the actual production plant equipment layout and cleanliness level differences, the absolute sterilization device 340 is often far away from the filling machine and the pipeline is long. Therefore, the material is filled into the aseptic bag through the aseptic bag filling machine, which is convenient for subsequent use and more flexible in process. Using an aseptic bag filling machine for pre-aseptic bag filling can avoid the limitations caused by the production line equipment layout and flexibly meet the needs of different production processes.

[0068] In this embodiment, the aseptic bag filling machine is highly flexible and can flexibly meet the filling needs of materials with various viscosities. It has rich packaging specifications and can fill 5L, 10L, 20L and larger 500L and 1000L.

[0069] When in use, the valve body is not limited to be a stop valve, an electric valve, a solenoid valve or other types of valves that can be turned on and off.
