However, those skilled in the art will understand that many technical details are presented in the various embodiments of this application to facilitate a better understanding of the application. However, the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0035] like Figure 1 As shown, one embodiment of this application provides a ready-to-sell fermented food production system, such as... Figure 1 As shown, the production system specifically includes a cleaning unit S1, a fermentation broth preparation unit S2, a packaging unit S3, and a fermentation unit S4; wherein,

[0036] The cleaning unit S1 is used to clean fruit and vegetable raw materials, such as peppers, radishes, and cabbages.

[0037] The fermentation broth preparation unit S2 is used to prepare the fermentation broth and includes a mixing tank 2. The outlet of the mixing tank 2 is located at the bottom and is equipped with an infrared sensor 2-4 and a switching valve 2-3. Preferably, the mixing tank 2 is equipped with an electromagnetic stirrer 2-1 inside and an electromagnetic driver located on the top exterior of the mixing tank. The electromagnetic driver has an electromagnetic coil assembly and a stator core. The rotating shaft of the electromagnetic stirrer 2-1 is rotatably connected to the top wall of the mixing tank 2, and it has a cross-shaped neodymium iron boron permanent magnet inside. When the electromagnetic driver is energized, it can drive the electromagnetic stirrer 2-1 to rotate. When the fermentation broth raw materials are poured into the mixing tank 2, they are stirred to make them uniform and fully dissolved. The electromagnetic stirrer 2-1 is kept rotating to prevent the fermentation broth from settling in the mixing tank 2.

[0038] The packaging unit S3 includes a conveyor belt 3-1, a weight sensor 3-2, a sealing device 3-3, and a gripper 3-4; the discharge port of the cleaning unit S1 is located near and above the starting end of the conveyor belt 3-1. The sealing device 3-3 is mounted on a frame near the end of the conveyor belt 3-1, and is fixed relative to the frame of the conveyor belt 3-1. The mixing tank 2 is located above the middle of the conveyor belt 3-1.

[0039] The weight sensing device 3-2 and the gripper 3-4 are fixed on the conveyor belt 3-1 and rotate with the conveyor belt 3-1. The fermentation container is placed on the weight sensing device 3-2 and the gripper 3-4 holds the fermentation container in preparation for the injection of fruits, vegetables and fermentation liquid. The sealing device 3-3 is used to seal the fermentation container containing fruits, vegetables and fermentation liquid.

[0040] Fermentation unit S4 includes a fermentation chamber 4-1 and a sterilization device 4-2; the fermentation chamber 4-1 is used to store sealed fermentation containers at the fermentation temperature; the sterilization device 4-2 is used to kill microorganisms in the fruits, vegetables and fermentation liquid in the fermentation containers after the fermentation cycle is completed. Optionally, the conveyor belt 3-1 of packaging unit S3 extends to the entrance of fermentation chamber 4-1, or the two are connected by another conveyor belt to transport the sealed fermentation containers to fermentation chamber 4-1.

[0041] The ready-to-sell fermented food production system provided in this application can sterilize and clean fruits and vegetables. The cleaned raw materials are directly added to the fermentation container, mixed with the fermentation liquid prepared in the ingredient tank 2, and then packaged. After fermentation in the fermentation chamber 4-1, the product is sterilized after fermentation and is ready for sale. The operation process is simple and easy to control, which is conducive to industrial production.

[0042] In one embodiment of this application, for automated production, the system further includes a PLC control unit electrically connected to the infrared sensor 2-4 and the switching valve 2-3. The control unit controls the opening and closing of the switching valve 2-3 and its duration based on the detection results of the infrared sensor 2-4, so as to add a first preset weight of fermentation liquid into the fermentation container. The PLC control unit is also electrically connected to the weight sensor 3-2 and the material valve at the outlet of the cleaning unit S1, and controls the opening and closing of the material valve and its duration based on the detection results of the infrared sensor 2-4, so as to add a second preset weight of fruits and vegetables into the fermentation container.

[0043] In an alternative solution to this application, the infrared sensing device 2-4 and the weight sensing device 3-2 can be omitted. Instead, a conventional timing synchronization method can be used. During the periodic pause of the conveyor belt 3-1, the outlet of the cleaning unit S1 and the outlet of the mixing tank 2 can be opened to inject the fruits, vegetables and fermentation liquid into different fermentation containers. Only the size of the outlet of the cleaning unit S1 and the outlet of the mixing tank 2 needs to be set to ensure the output volume. Alternatively, the outlet of the cleaning unit S1 and the outlet of the mixing tank 2 can be set closer together to simultaneously inject the fruits, vegetables and fermentation liquid into the fermentation containers.

[0044] In one embodiment of this application, the cleaning unit S1 includes an electrolytic water generator 1-1 and a fruit and vegetable cleaning device 1-2.

[0045] The water electrolysis generator 1-1 is used to electrolyze pure water and sodium chloride solution into chlorine-containing weakly acidic electrolyzed water, which is then used for soaking and sterilizing fruits and vegetables. The effective chlorine content of the electrolyzed water can be adjusted by changing the ratio of pure water to sodium chloride solution in the water electrolysis generator 1-1 to meet different sterilization requirements. The water electrolysis generator 1-1 includes an electrolysis tank and a soaking tank. The electrolysis tank is equipped with an anode plate, a cathode plate, and an ion exchange membrane. The ion exchange membrane divides the electrolysis tank into an anode area and a cathode area. Acidic electrolyzed water (containing HClO) is generated in the anode area, which is connected to the soaking tank. A suspension crossbar is fixedly connected to the soaking tank. The suspension crossbar is rotatably connected to a soaking basket for holding fruits and vegetables via two connecting rods. One end of each connecting rod is rotatably connected to the side of the soaking basket, and the other end is rotatably connected to the suspension crossbar. Optionally, the water electrolysis generator 1-1 can be a commercially available hypochlorous acid generator, such as the SW-G20 hypochlorous acid generator from Zhejiang Shuixiong Technology Co., Ltd.

[0046] The fruit and vegetable cleaning equipment 1-2 includes a cleaning chamber, a cylindrical screen rotatably connected to and located within the cleaning chamber, and a motor. The cleaning chamber is a cylindrical shape with both ends closed. An inlet is located on the upper side of the outer circumference of one end, and an outlet is located on the lower side of the outer circumference of the other end. The cleaning chamber is placed horizontally and inclined towards the inlet end to store a certain amount of water. A closable drain outlet is located on the lower side of the inlet end of the cleaning chamber. The soaking frame of the electrolytic water generator 1-1 can rotate around a suspension crossbar and flip itself to pour the fruits and vegetables inside into the inlet of the cleaning chamber of the fruit and vegetable cleaning equipment 1-2. There is a gap between the inner wall of the cleaning chamber and the outer circumference of the cylindrical screen. A spiral blade is fixedly connected inside the cylindrical screen, and the overall extension direction of the spiral blade is consistent with the axis of the cylindrical screen. One end of the spiral blade extends out of the screen and is located below the feed inlet of the cleaning chamber; the rotating shaft of the spiral blade at this end passes through the cleaning chamber and is rotatably connected to the cleaning chamber, while the other end passes through the cleaning chamber (near the discharge port) and is connected to the motor. The motor drives the spiral blade to rotate, and the rotation drives the fruits and vegetables entering the cleaning chamber from the feed inlet to rotate into the screen for cleaning. The fruits and vegetables then rotate out at the other end of the spiral blade and the screen and enter the discharge port of the cleaning chamber. Preferably, a hopper for temporarily storing fruits and vegetables is provided between the end of the screen and the discharge port to meet the intermittent feeding needs of different fermentation containers at the discharge port.

[0047] The bottom of the washing chamber is equipped with multiple air holes for connecting to an external bubble generator, which can be a turbine fan or an air compressor. The bubble generator circulates air into the water in the washing chamber through the air holes to form bubbles, causing the fruits and vegetables to disperse and tumble together.

[0048] In one embodiment of this application, there are multiple weight sensing devices 3-2 and grippers 3-4, and they are connected one-to-one to the conveyor belt 3-1.

[0049] Optionally, the conveyor belt 3-1 is driven by a servo motor, and the PLC control unit is also electrically connected to the servo motor to control the conveyor belt 3-1 to pause periodically based on the detection result of whether there is a fermentation container below it by the infrared sensor 2-4, so as to inject the fermentation liquid into the fermentation container during the pause.

[0050] In one embodiment of this application, the fermentation unit S4 further includes a gripping device, which can be a robotic arm or a benchtop robotic arm, to grip the sealed fermentation container from the conveyor belt 3-1 and place it into the fermentation temperature environment of the fermentation chamber 4-1. Optionally, the sterilization device 4-2 includes a high-temperature sterilization component and a cooling component. The high-temperature sterilization component can use pasteurization to sterilize the fruits, vegetables, and fermentation liquid in the fermentation container. Optionally, the high-temperature sterilization component is a heating chamber equipped with a heater, which is connected to the fermentation chamber 4-1, and a transmission component is provided in the channel. The heater raises the temperature inside the heating chamber to 60°C to sterilize the contents placed inside the heating chamber.

[0051] Optionally, the fermentation chamber 4-1 is equipped with a temperature control component and a ventilation component. The temperature control component regulates the temperature inside the fermentation chamber 4-1 to meet the requirements of different fruits and vegetables and the fermentation cycle. Multiple ventilation components can be installed inside the fermentation chamber 4-1 to ensure a uniform temperature in different areas, preventing the fermentation container or parts of the fermentation chamber 4-1 from exceeding the fermentation temperature due to heat release during fermentation. The temperature control component includes a thermometer, an air heater, and a fan. The thermometer and air heater are located inside the fermentation chamber 4-1. The fan is mounted on the wall of the fermentation chamber 4-1 to blow cool outside air into the fermentation chamber 4-1 to lower its temperature.

[0052] In one embodiment of this application, the production system further includes a fermentation container feeding device located below the conveyor belt 3-1, for supplying empty fermentation containers to the gripper 3-4. Alternatively, the gripper 3-4 can be manually fed. Optionally, the gripper 3-4 includes a connecting plate for fixed connection to the outer surface of the conveyor belt 3-1. The surface of the connecting plate is provided with two connecting rods perpendicular to the conveyor belt 3-1. The top of the connecting rods is provided with an arc-shaped clamping portion for clamping a portion of the outer periphery of each fermentation container from one side. Both the connecting rods and the clamping portions are elastic.

[0053] In one embodiment of this application, the sealing device includes a multi-degree-of-freedom robotic arm and a pneumatic gripper, both electrically connected to a PLC control unit. The multi-degree-of-freedom robotic arm and the pneumatic gripper are connected; the pneumatic gripper grips the cap used to seal the fermentation container, and the multi-degree-of-freedom robotic arm adjusts the position of the pneumatic gripper. A servo motor and torque sensor within the multi-degree-of-freedom robotic arm cause the pneumatic gripper to rotate the cap, thereby sealing the fermentation container. Preferably, the sealing device 3-3 is also equipped with a photoelectric sensor to accurately locate the position of the fermentation container on the conveyor belt 3-1. The fermentation container can be a tank.

[0054] It should be noted that the specific computer programs involved in the timing and operation steps of the PLC control unit controlling the switching valves of the batching tank 2, the material valves of the cleaning unit S1, the infrared sensing device 2-4, the weight sensing device 3-2, the sealing device 3-3, etc., in this application are all conventional adjustments to the prior art and are not within the scope of protection of this application.

[0055] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this application and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this application should be included within the protection scope of this application.
