[0063] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0064] Figure 1 A schematic diagram of the structure of a material device provided in an embodiment of the present application, Figure 2 This is a schematic diagram of the principle of the first process in the material device provided in the embodiment of the present application. Figure 3 This is a schematic diagram of the principle of the second process in the material device provided in the embodiment of the present application. Figure 4 This is a schematic diagram of the principle of the third process in the material device provided in an embodiment of the present application.

[0065] like Figures 1 to 4 As shown, the embodiment of the present application provides a material device 100, including:

[0066] Material tank 110, material tank 110 is used for transporting materials;

[0067] It should be noted that the material may include milk, yogurt or other liquid materials, and the material tank 110 is used to transport the material, so as to facilitate adding some bacteria into the material during the transportation process.

[0068] A strain adding tank 120, wherein the strain adding tank 120 has a containing cavity, and the containing cavity is used to store strain additives;

[0069] It should be noted that various bacterial additives are stored in the bacterial addition tank 120, and the bacterial additives may include mixed additives of bacterial strains and milk products. The bacterial strains may be selected from a bacterial group, such as: Lactobacillus, Bacteroides, Parabacteroides, Ehrlichia, Bifidobacterium, Butyricoccus, Oscillococcus, Bacillus and any combination thereof.

[0070] A sterile air tank 130 , wherein sterile air is stored in the sterile air tank 130 ;

[0071] In addition, the sterile air stored in the sterile air tank 130 facilitates the cleaning of the bacteria adding tank 120 later.

[0072] After being connected to the sterile air tank 130, the strain addition tank 120 is cleaned and sterilized using sterile air, thereby achieving efficient recovery of materials and cleaning and sterilization of product components.

[0073] In some embodiments, the sterile air in the sterile air tank 130 of the present invention may be sterile air and high-temperature steam.

[0074] A control unit, the control unit includes a first controller and a second controller, the first controller is used to control the connectivity between the material tank 110 and the culture addition tank 120 so that the culture additives can be added to the material, wherein the second controller controls the connectivity between the culture addition tank 120 and the sterile air tank 130 so that after the addition of the culture additives is completed, part of the culture additives remaining in the culture addition tank 120 can flow to the material tank 110 under the introduction of sterile air.

[0075] It should be noted that the first controller is used to control the connectivity between the material tank 110 and the culture addition tank 120. When it is not necessary to add culture additives, the material tank 110 and the culture addition tank 120 are in a disconnected state. When it is necessary to add culture additives, the material tank 110 and the culture addition tank 120 are in a connected state so that the culture additives can be added to the material.

[0076] When the addition of the bacterial strain additive is completed, it is necessary to introduce high-pressure sterile air into the bacterial strain adding tank 120. The bacterial strain adding tank 120 is purged by the injected high-pressure sterile air, so that the remaining bacterial strain additive can fully flow into the material tank 110 under the purge of sterile air, and merge with the material in the material tank 110 again. The fused material finally flows out of the material tank 110 to proceed to the next procedure.

[0077] Through the above-mentioned settings, that is, through the matching settings between the first controller, the second controller, the strain adding tank 120 and the sterile air tank 130, it is possible to add strain additives to the materials in the material tank 110 under the control of the first controller during normal material transportation, or not to add strain additives to the material tank 110. After the addition is completed, high-pressure sterile air can be introduced into the strain adding tank 120 under the control of the second controller. The strain adding tank 120 is cleaned and sterilized by the injected high-pressure sterile air, thereby achieving efficient material recovery and cleaning and sterilization of product components. The strain adding tank 120 is emptied, reducing the waiting time for re-addition and improving production efficiency. It is best to isolate different batches of materials in the middle of continuous addition to reduce the mixing of residual materials and avoid quality risks. In addition, the closed container and the pipeline are not in contact with the outside world, and positive pressure protection avoids strain contamination.

[0078] In some optional embodiments, a liquid level sensor 140 is provided in the culture addition tank 120, and the liquid level sensor 140 is used to detect the remaining amount of the culture additive remaining in the containing cavity. The second controller controls the connectivity between the culture addition tank 120 and the sterile air tank 130 according to the liquid level signal received from the liquid level sensor 140.

[0079] It should be noted that when it is necessary to add bacterial strain additives, the material tank 110 and the bacterial strain adding tank 120 are in a connected state so that the bacterial strain additives can be added to the material. The liquid level sensor 140 detects the remaining bacterial strain additive. When the detected value reaches the preset threshold, it means that the addition of the bacterial strain additive is completed. At this time, the second controller controls the connection state between the bacterial strain adding tank 120 and the sterile air tank 130, so that the two are in a connected state, and then high-pressure sterile air is introduced into the bacterial strain adding tank 120. Through the injected high-pressure sterile air, the bacterial strain adding tank 120 is cleaned and sterilized using sterile air, thereby realizing efficient recovery of materials and cleaning and sterilization of product components.

[0080] like Figure 1 As shown, in some optional embodiments, the liquid level sensor 140 is disposed at the bottom end of the accommodating cavity.

[0081] In some examples, the liquid level sensor 140 and the culture addition tank 120 may be connected in a detachable connection manner or a fixed connection manner.

[0082] For example, bolts, buckles or hanging connections are used. Specifically, the embodiments of the present application are not too restrictive here.

[0083] like Figures 1 to 4As shown, in some optional embodiments, the material tank 110 is provided with a material inlet 111 and a material outlet 112 that are interconnected, the accommodating chamber has a gas inlet 121, a communication port 122 and a strain outlet 123, the strain outlet 123 is connected to the material outlet 112, and the gas inlet 121 and the communication port 122 are respectively connected to the strain outlet 123.

[0084] The first controller is used to control the communication state between the material inlet 111 and the communication port 122 , and the second controller is used to control the communication state between the gas inlet 121 and the sterile air tank 130 .

[0085] like Figure 1 As shown, it should be noted that when there is no need to add bacteria, the material enters the material tank 110 through the material inlet 111 and then flows out from the material outlet 112.

[0086] like Figure 2 As shown, when it is necessary to add bacterial additives, the material inlet 111 and the communication port 122 are in a connected state so that the bacterial additives can be added to the material.

[0087] like Figure 3 As shown, when the addition of the bacterial strain additive is completed, the gas inlet 121 is connected to the sterile air tank 130, and high-pressure sterile air is injected into the sterile air tank 130 to purge the bacterial strain addition tank 120, so that the remaining part of the bacterial strain additive can fully flow into the material tank 110 under the purge of sterile air and merge with the material in the material tank 110 again.

[0088] like Figures 1 to 4 As shown, in some optional embodiments, a valve unit 150 is further included, and the valve unit 150 includes a first valve 151 and a second valve 152;

[0089] The first valve 151 is arranged between the material inlet 111 and the connecting port 122 , and the first controller is used to control the working state of the first valve 151 . The second valve 152 is arranged between the gas inlet 121 and the sterile air tank 130 , and the second controller is used to control the working state of the second valve 152 .

[0090] It should be noted that the opening and closing state of the first valve 151 is controlled by the first controller, thereby controlling the communication state between the material inlet 111 and the communication port 122 .

[0091] Correspondingly, the second controller controls the opening and closing state of the second valve 152 , thereby controlling the communication state between the gas inlet 121 and the sterile air tank 130 .

[0092] like Figures 1 to 4As shown, in some optional embodiments, the valve unit 150 includes a third valve 153, the first valve 151 has a first passage and a second passage, the first passage is located between the first valve 151 and the third valve 153, and the second passage is located between the first valve 151 and the communication port 122;

[0093] The control unit further includes a third controller, which is used to control the third valve 153 to open, so that the material inlet 111 and the material outlet 112 are connected through the first passage.

[0094] It should be noted that the first valve 151 can be a T-type valve, and can have a first passage and a second passage. When the first passage is in an open state, it means that the first valve 151 and the third valve 153 are connected, and then the material enters the material tank 110 from the material inlet 111, passes through the third valve 153, and finally flows out through the material outlet 112. The above is a material transportation trajectory without the need to add bacterial additives.

[0095] When the second passage is in an open state, it means that the first valve 151 and the connecting port 122 are connected, and then the material enters the material tank 110 from the material inlet 111. At this time, the third controller is used to control the third valve 153 to be in a closed state, which means that the first passage is in a closed state, and the material enters the culture addition tank 120 through the second passage, and finally flows out through the material outlet 112. The above is the material transportation trajectory that requires the addition of culture additives.

[0096] like Figures 1 to 4 As shown, in some optional embodiments, a processor, a first air pressure sensor 160, a second air pressure sensor 170 and a third air pressure sensor 180 are further included, and the first air pressure sensor 160, the second air pressure sensor 170, the third air pressure sensor 180, the second controller and the third controller are all connected to the processor;

[0097] The first air pressure sensor 160 is disposed at the air outlet of the sterile air tank 130 and is used to detect the first air pressure of the air outlet of the sterile air tank 130. The second air pressure sensor 170 is disposed at the gas inlet 121 and is used to detect the second air pressure of the gas inlet 121. The third air pressure sensor 180 is disposed at the material outlet 112 and is used to detect the third air pressure of the material outlet 112.

[0098] When the processor monitors that the second air pressure and the third air pressure are both lower than the first air pressure, the second controller controls the second valve 152 to open, and the third controller controls the third valve 153 to open.

[0099] It should be noted that such a configuration prevents the sterile air in the sterile air tank 130 from flowing back.

[0100] It should be noted that the processor is used to control the first air pressure sensor 160, the second air pressure sensor 170, the third air pressure sensor 180, the first controller, the second controller and the third controller. The first air pressure sensor 160, the second air pressure sensor 170, the third air pressure sensor 180, the first controller, the second controller and the third controller transmit their control signals to the processor, and can receive and execute commands sent by the processor.

[0101] The processor is the control center of the material device 100. It uses various interfaces and lines to connect various parts of the entire material device 100, and executes various functions of the material device 100 and processes data by running or executing software programs and / or modules stored in the memory and calling data stored in the memory, thereby monitoring the material device 100 as a whole.

[0102] In some embodiments, the processor may include one or more processing units; preferably, the processor may integrate an application processor and a modem processor, and optionally, the application processor mainly processes an operating system, a user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the modem processor may not be integrated into the processor.

[0103] Figure 5 The schematic diagram of the fourth process in the material device provided in the embodiment of the present application is as follows: Figures 1 to 5 As shown, in some optional embodiments, the material tank 110 also includes an exhaust port 113. When part of the bacterial strain additives retained in the bacterial strain addition tank 120 flows out, the exhaust port 113 is configured to be connected to the bacterial strain outlet 123 to allow the sterile air entering the containing chamber to be discharged.

[0104] It should be noted that the exhaust port 113 is provided so that after the high-pressure sterile air is introduced, in order to restore the previous state, the internal high-pressure gas needs to be discharged to facilitate the subsequent process.

[0105] like Figures 1 to 5 As shown, in some optional embodiments, the valve unit 150 also includes a fourth valve 154 , which has a third passage and a fourth passage. The third passage is located between the culture outlet 123 and the material outlet 112 , and the fourth passage is located between the culture outlet 123 and the exhaust port 113 .

[0106] It should be noted that the fourth valve 154 can be a T-type valve. When it is necessary to add bacterial strain additives, the material tank 110 and the bacterial strain addition tank 120 are in a connected state. At this time, the material enters the material tank 110 through the material inlet 111, and the material enters the bacterial strain addition tank 120 through the second passage, and then mixes with the bacterial strain additive in the bacterial strain addition tank 120. The mixed material passes through the third passage and finally flows out through the material outlet 112.

[0107] After the high-pressure sterile air is introduced, in order to restore the previous state, the fourth passage of the fourth valve 154 is in an open state, which means that the culture outlet 123 and the material outlet 112 are in a connected state, so that the high-pressure sterile air in the culture addition tank 120 flows through the culture outlet 123 to the fourth passage, and then is discharged through the exhaust port 113.

[0108] In some optional embodiments, the valve unit 150 further includes a fifth valve 155 and a sixth valve 156. The fifth valve 155 is disposed at the exhaust port 113, and the sixth valve 156 is disposed at the openings of the material tank 110 and the strain addition tank 120, and is connected to an external water source.

[0109] It should be noted that the fifth valve 155 is used to control the opening state of the exhaust port 113 .

[0110] In some embodiments, the fifth valve 155 may be a one-way valve.

[0111] It should be noted that the setting of the sixth valve 156 facilitates the connection of the openings of the material tank 110 and the bacterial strain adding tank 120 with the external water source, so as to facilitate the cleaning of the material tank 110 and the bacterial strain adding tank 120 after the work is completed.

[0112] In some embodiments, the sixth valve 156 may be a one-way valve.

[0113] The material device provided in the embodiment of the present application includes: a material tank, which is used for transporting materials; a strain adding tank, which has a containing cavity, and the containing cavity is used to store strain additives; a sterile air tank, in which sterile air is stored; a control unit, which includes a first controller and a second controller, and the first controller is used to control the connectivity between the material tank and the strain adding tank so that the strain additive is added to the material, wherein the second controller controls the connectivity between the strain adding tank and the sterile air tank so that after the strain additive is added, part of the strain additive remaining in the strain adding tank flows to the material tank under the introduction of sterile air.

[0114] Through the matching settings among the first controller, the second controller, the strain adding tank and the sterile air tank, it is possible to add strain additives to the materials in the material tank under the control of the first controller during normal material transportation, or not to add strain additives to the material tank. When the addition is completed, high-pressure sterile air can be introduced into the strain adding tank under the control of the second controller. The strain adding tank is cleaned and sterilized by the injected high-pressure sterile air, thereby achieving efficient material recovery and cleaning and sterilization of product components. The strain adding tank is emptied, reducing the waiting time for adding again and improving production efficiency. It is best to isolate different batches of materials in the middle of continuous addition to reduce the mixing of residual materials and avoid quality risks. In addition, the closed container and the pipeline are not in contact with the outside world, and the positive pressure protection avoids the contamination of the strain.
