[0036] The specific preparation process of bird's nest stewing and sterilization process includes the following steps:

[0037] Step 1: The raw materials are tested for microorganisms, heavy metals, pesticide residues, and nutrients, and then sorted to remove impurities and feathers to ensure the purity of the bird's nest;

[0038] Step 2: Feed the semi-finished bird's nest through a special feeding department. After the feeding is completed, the semi-finished bird's nest will be filled with sugar water through the filling department;

[0039] Step 3: After the filling is completed, the machine automatically seals and sends it to the high-temperature stewing furnace for stewing. The sterilizer 1 is used for high-temperature sterilization to eliminate possible bacteria and viruses to ensure the safety and hygiene of the bird's nest. At the same time, the temperature control processing is used to better precipitate nutrients such as protein, active amino acids and bird's nest acid in the bird's nest, making it more nutritious (releasing more than 95% bird's nest acid) and retaining its natural nutrients.

[0040] Step 4: After sterilization, the bird's nest is first dried with air shower and then placed at room temperature for 15 days. It is then inspected by a high-intensity light. The first step is to check for foreign matter and product appearance, and the second step is to check for foreign matter and product morphology standards to ensure higher product quality.

[0041] Step 5: Package and label the products that have passed the inspection and store them in a suitable environment.

[0042] The first partition 21, the second partition 22 and the third partition 23 are moved by adjusting the structure, and the bird's nest after filling is placed on the food tray 20 and separated by the first partition 21, the second partition 22 and the third partition 23. Then the tray wheel 18 at the bottom of the tray frame 19 is placed on the guide rail 17, and the tray frame 19 is moved so that the bird's nest after filling enters the sterilizer 1. The parameter data of the PLC is input through the controller to control the sterilizer 1 for sterilization. At the beginning of the temperature rise, water is injected through the process water inlet 12 so that a proper amount of water is retained at the bottom of the sterilizer 1. This part of water is passed through the circulation pump 1 0, the product is sprayed and heated from top to bottom using the second delivery pipe 15 and the spray pipe 16, and the imported high-efficiency heat exchanger 3 is used. The bird's nest can be quickly heated from 20 degrees to 121 degrees within 10 to 15 minutes. During the heating process, the circulating water is indirectly heated through the heat exchanger. The circulating water in the sterilizer 1 is always in a sterile state when heated or cooled. The circulating water is usually used to pressurize the kettle. The steam generated by the circulating water after heating is injected into the sterilizer 1 through the first connecting pipe 2 to increase the pressure. The heat exchange steam passes through another circuit of the heat exchanger and adjusts the temperature according to the temperature setting value. Then, the circulating water is evenly sprinkled on the surface of the entire product from top to bottom through the distribution plate on the top of the sterilizer. The circulating water that has washed the product is collected at the bottom of the container and flows out after passing through the filter 13 and the collection pipe. During the heating and sterilization period, the valve is automatically controlled by the program to introduce the heat exchange steam into the primary circuit of the heat exchanger 3. Condensed water is automatically discharged from the steam trap. During the cooling phase, cooling water is injected into the primary circuit of the heat exchanger 3. The cooling water is regulated by an automatic valve located at the inlet of the heat exchanger 3 and is controlled by the program. Since the cooling water does not come into contact with the inside of the container, it is not contaminated and can be reused. During the whole process, the pressure inside the autoclave 1 is controlled by the program through two automatic valves that feed and discharge the autoclave 1. When the sterilization is finished, an alarm signal will be issued to prompt that the door can be opened and the materials can be unloaded, and then the next batch of products can be prepared for sterilization.

[0043] like Figure 1 to Figure 2 As shown, support seats are provided at both ends of the bottom of the sterilizing kettle 1, the second connecting pipe 9 is located in the middle of the support seat, and one end thereof extends to one side of the sterilizing kettle 1, and the first partition 21, the second partition 22 and the third partition 23 are all made of high temperature resistant PE material.

[0044] The support seat facilitates the support and fixation of the sterilizing kettle 1, so that the sterilizing kettle 1 remains stable during operation. The second connecting pipe 9 facilitates the connection of the circulating pump 10, so that the circulating water inside the sterilizing kettle 1 can be circulated. High-temperature resistant PE partitions are used to isolate each layer of food. Since the PE partitions have a large punching rate, smooth steam circulation can be ensured.

[0045] like Figures 4 to 6 As shown, the adjustment structure includes a fixed plate 24, a movable groove is opened on one side of the fixed plate 24, first sliders 25 are fixedly installed on both sides of the first partition plate 21, second sliders 26 are fixedly installed on both sides of the second partition plate 22, and third sliders 27 are fixedly installed on both sides of the third partition plate 23. The first slider 25, the second slider 26 and the third slider 27 are all movably connected with the movable groove, sliding grooves are opened on both sides of the fixed plate 24, slots are opened near both sides of the sliding grooves of the first slider 25 and the second slider 26, and limiting structures 28 are arranged on both sides of the first slider 25.

[0046] The limiting structure 28 is moved to both sides so that the limiting structure 28 no longer limits the first slider 25. The first slider 25 is moved to drive the first partition 21 to move upward, so that the first slider 25 pushes the second slider 26, the third slider 27, the third partition 23 and the second partition 22 to move upward, thereby separating the first partition 21 from the tray frame 19. The limiting structure 28 is then moved to limit the first slider 25, thereby facilitating the placement of the food tray 20 on the tray frame 19. The first slider 25 is then moved to drive the first partition 21 to move to the top of the food tray 20. The second slider 26 is then limited by the limiting structure 28 to separate the first partition 21 from the second partition 22. The next food tray 20 is then placed on the first partition 21. The limiting structure 28 is then moved so that the second slider 26 drives the second partition 22 to move to the top of the food tray 20. Another food tray 20 is placed through the second partition 22. The third slider 27 is moved so that the third partition 23 covers it.

[0047] like Figures 7 and 8 As shown, the limiting structure 28 includes an insertion rod 281, one side of which is plugged into the slot, a connecting block 282 is fixedly installed on one side of the insertion rod 281, a compression spring 283 is fixedly installed on one side of the connecting block 282, and a limiting block 284 is fixedly installed on one end of the compression spring 283. The limiting blocks 284 are located on both sides of the fixed plate 24 and are slidably connected to the slide groove.

[0048] By pulling the limiting block 284 to both sides, the compression spring 283 is stretched, and the compression spring 283 drives the insertion rod 281 to the outer side of the slot, and the insertion rod 281 no longer limits the first slider 25 or the second slider 26, thereby facilitating the movement of the first partition 21 and the second partition 22, and facilitating the placement of the food tray 20. After the movement is completed, the limiting block 284 is pushed to move along the slide groove, driving the compression spring 283 and the insertion rod 281 to move to the first slider 25 or the second slider 26 position, and the limiting block 284 is released. Under the elastic action of the compression spring 283, the insertion rod 281 is inserted into the slots on both sides of the first slider 25 or the second slider 26 to limit the first slider 25 and the second slider 26, thereby facilitating the limitation of the food tray 20 and maintaining stability.

[0049] like Figures 7 to 9 As shown, the bottom of the fixed plate 24 is fixedly installed on the top of the tray frame 19, and the fixed plate 24 is located at both ends of the first partition plate 21, the second partition plate 22 and the third partition plate 23. A groove is opened at the top of the fixed plate 24 and located on one side of the movable groove, and a movable opening is opened on one side of the groove. Two circular grooves are opened at the bottom of the groove and located inside the fixed plate 24, and an electric push rod 30 is fixedly installed inside the two circular grooves. A connecting plate 31 is fixedly installed at the bottom of the electric push rod 30, and a connecting spring is fixedly installed on the top of the third slider 27 and located between the two limiting rods 29, and one end of the connecting spring is fixedly installed on the inner wall of the top of the connecting plate 31.

[0050] By starting the electric push rod 30, the connecting plate 31 is pushed out of the groove, so that the connecting spring is stretched, so as to lengthen the length of the internal movable groove of the fixed plate 24, so that when the first slider 25, the second slider 26 and the third slider 27 move, the first partition 21, the second partition 22 and the third partition 23 can move upward, and the distance between the first partition 21 and the second partition 22, and the second partition 22 and the third partition 23 can be adjusted, so that when the food plate 20 is placed on the first partition 21 and the second partition 22, the distance will not be too small, thereby affecting the placement of the food plate 20.

[0051] like Figures 6 to 9 As shown, a limiting plate 32 is provided at the movable opening, the connecting plate 31 is located inside the groove, and one side of the connecting plate 31 is slidably connected to the inner wall of the groove, the fixed plate 24 is located on one side of the connecting plate 31, the fixed plate 24 is movably connected to the connecting plate 31, two limiting grooves are provided on the top of the connecting plate 31, and a limiting rod 29 is fixedly installed on the top of the third slider 27, and the limiting rod 29 is plugged into the limiting groove.

[0052] When the third slider 27 moves to the bottom end of the connecting plate 31, the limiting rod 29 is plugged into the limiting groove to fix the third partition plate 23. When the electric push rod 30 pushes the connecting plate 31 to move upward, one side of the connecting plate 31 moves upward along the limiting plate 32, so as to facilitate the connecting plate 31 to move out of the groove. After the length of the movable groove is lengthened, the limiting plate 32 is at the movable mouth, so that the first slider 25, the second slider 26 and the third slider 27 can still move upward along the movable groove and the limiting plate 32, thereby facilitating adjustment.

[0053] like Figure 2 , Figure 3 , Fig.10 , Fig.11As shown, the mounting plate 14 is in a semi-arc shape, one end of the second delivery pipe 15 is located outside the mounting groove, the second delivery pipe 15 is rotatably connected to the mounting groove, a second fixed groove is provided on the side of the mounting plate 14 close to the kettle door, a motor 33 is fixedly installed inside the second fixed groove, a rotating rod 34 is transmission-connected to the output end of the motor 33, a first gear 35 is fixedly installed at one end of the rotating rod 34, a second gear 36 is meshed with one side of the first gear 35, the middle part of the second gear 36 is fixedly installed with one end of the second delivery pipe 15, the first gear 35 and the second gear 36 are both located on one side of the mounting plate 14, and are rotatably connected to one side of the mounting plate 14.

[0054] By starting the motor 33, the rotating rod 34 and the first gear 35 are driven to rotate, so that the first gear 35 drives the second gear 36 and the second conveying pipe 15 to rotate. By controlling the motor 33 to drive the rotation of the rotating rod 34, it is convenient to control the rotation of the first gear 35 and the second gear 36, so that the second conveying pipe 15 can drive the spray pipe 16 to deflect, so as to increase the spraying angle and range of the spray pipe 16, and facilitate the effect of heating sterilization.

[0055] like Figure 10 to Figure 11 As shown, the spray pipe 16 includes a fixed pipe 37, a connecting ring 38 is provided at the bottom of the fixed pipe 37, a plurality of rotating plates 39 are hinged on one side of the connecting ring 38, a moving rod 40 is hinged on the outer side of the rotating plate 39, a moving ring 41 is fixedly installed on the top of the moving rod 40, an electric telescopic rod 42 is fixedly installed on the top of the moving ring 41, the rotating plates 39 are arc-shaped on the side close to each other, the moving rod 40 is located on the outer side of the connecting ring 38, the inner wall of the moving ring 41 is slidably connected to the outer side of the fixed pipe 37, and a fixed ring 43 is fixedly installed on the top of the electric telescopic rod 42.

[0056] The electric telescopic rod 42 is fixed by the fixing ring 43, and the electric telescopic rod 42 is started to push the moving ring 41 along the fixing ring 43 to drive the moving rod 40 to move toward the food plate 20. The moving rod 40 drives the rotating plate 39 to deflect, so that multiple rotating plates 39 are deflected to the outside of the fixed tube 37, thereby increasing the spraying range and area of ​​the fixed tube 37, thereby facilitating the improvement of the spray heating effect and the sterilization effect.

[0057] Working principle: When in use, by pulling the limiting block 284, the compression spring 283 is stretched, so that the insertion rod 281 moves out of the slots on both sides of the first slider 25, pushing the first partition 21 to move upward, so that the first slider 25 pushes the second slider 26 and the third slider 27 to move upward along the inner wall of the movable groove, so that the first partition 21 pushes the second partition 22 and the third partition 23 to move upward, and the distance between the first partition 21 and the tray frame 19 is adjusted, and then the limiting block 284 is moved along the slide groove to the position of the first slider 25, and by loosening the limiting block 284, under the action of the compression spring 283, the insertion rod 281 is inserted into the slots on both sides of the first slider 25 to limit the position of the first slider 25, and then the food tray 20 containing the bird's nest is placed between the tray frame 19 and the first partition 21, and then the second slider 26 is moved to drive the second partition 22 to move, so that the third slider 27 drives the third partition 23 to move upward along the movable groove, when the first partition 21 and the second partition After the distance between the plates 22 is adjusted, by moving the limiting block 284, the insertion rod 281 is moved out of the slots on both sides of the first slider 25 under the action of the compression spring 283, and the limiting block 284 is moved to the second slider 26. The insertion rod 281 is pushed into the slot of the second slider 26 by the elastic action of the compression spring 283 to limit the second slider 26, and then the food tray 20 is placed between the first partition 21 and the second partition 22, and then the electric push rod 30 is started to push the connecting plate 31 out of the groove, and the third slider 27 is pushed to drive the third partition 23 to move upward, so that the limiting rod 29 on the third slider 27 is inserted into the limiting groove at the bottom of the connecting plate 31. At the same time, the connecting spring is compressed, so that the distance between the third partition 23 and the second partition 22 is adjusted, and the food tray 20 is placed between the third partition 23 and the second partition 22, and the third slider 27 is moved to move the third partition 23 to the top of the food tray 20, and finally the food tray 20 is placed on the third partition 23.

[0058] Then place the tray wheel 18 at the bottom of the tray frame 19 on the guide rail 17, move the tray frame 19 so that the bird's nest after filling enters the sterilizer 1, and input the parameter data of the PLC through the controller to control the sterilizer 1 for sterilization. At the beginning of the temperature rise, water is injected through the process water inlet so that a proper amount of water is retained at the bottom of the sterilizer 1. This part of water passes through the circulating pump 10, and the second conveying pipe 15 and the spray pipe 16 are used to spray and heat the product from top to bottom. By using the imported high-efficiency heat exchanger 3, the bird's nest can be quickly heated from 20 degrees to 121 degrees within 10 to 15 minutes. During the heating process, the circulating water is indirectly heated through the heat exchanger 3. The circulating water in the sterilizer 1 is always in a sterile state when heated or cooled. The circulating water is usually used to pressurize the inside of the kettle, and the steam generated by the circulating water after heating is injected into the sterilizer 1 through the first connecting pipe 2 to increase the pressure. The heat exchange steam passes through another circuit of the heat exchanger 3, and the temperature is adjusted according to the temperature setting value. Then, the circulating water is evenly sprinkled on the entire surface of the product from top to bottom through the distribution plate on the top part of the sterilizer. The circulating water that has washed the product is collected at the bottom of the container and flows out after passing through the filter 13 and the collection pipe. During the heating and sterilization period, the valve automatically controlled by the program guides the heat exchange steam into the primary circuit of the heat exchanger 3. Condensed water is automatically discharged from the steam trap. During the cooling stage, cooling water is injected into the primary circuit of the heat exchanger 3. The automatic valve at the inlet of the heat exchanger is regulated by the program. Since the cooling water does not come into contact with the inside of the container, it is not contaminated and can be reused. During the whole process, the pressure inside the sterilizer 1 is controlled by the program through two automatic valves to feed and discharge the sterilizer 1. When the sterilization is completed, an alarm signal will be issued to remind you that at this time, the door can be opened and the materials can be unloaded, and then the next batch of products can be prepared for sterilization.

[0059] When it is necessary to spray through the first conveying pipe 8 and the spray pipe 16, the electric telescopic rod 42 is started to push the moving ring 41 along the fixed ring 43 to drive the moving rod 40 to move toward the food tray 20, and the moving rod 40 drives the rotating plate 39 to deflect, so that multiple rotating plates 39 are deflected to the outside of the fixed pipe 37, and the motor 33 is started to drive the rotating rod 34 and the first gear 35 to rotate, so that the first gear 35 drives the second gear 36 and the second conveying pipe 15 to rotate, and the rotation of the rotating rod 34 driven by the motor 33 is controlled, so as to facilitate the control of the rotation of the first gear 35 and the second gear 36, so that the second conveying pipe 15 can drive the spray pipe 16 to deflect, so as to facilitate the expansion of the spraying range and area of ​​the first conveying pipe 8 and the spray pipe 16, thereby facilitating the improvement of the spray heating effect and the improvement of the sterilization effect.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
