A segmented heating pipe is arranged inside the heating cavity, and a water passing grille is slidably connected to the side of the heating cavity close to the cooking cavity. Three groups of temperature sensors are arranged on both ends of the inner wall of the cooking cavity from top to bottom. Multiple groups of heating pipes are arranged at the bottom end inside the cooking cavity, and multiple groups of bearing plates are arranged above the heating pipes at the bottom end inside the cooking cavity. The disadvantage of this utility model is that this equipment performs batch loading and unloading manually, which not only wastes time but also easily causes harm during the cooking process. Summary of the Invention

[0004] The present invention aims to overcome the deficiency in the prior art that manual batch processing is required for cooking, and provides a preparation process of prunes that can automatically feed and discharge during the cooking and sterilization process.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A preparation process of prunes specifically includes the following steps: Step 1: A cooking tank, a steam assembly, an arrangement tray, a conveying assembly, a spraying tank and a spraying assembly. A cooking cavity is provided on the cooking tank. An inlet hole is installed on one side of the cooking cavity, and an outlet hole is provided on the bottom surface of the cooking cavity. The arrangement tray is placed inside the cooking cavity. One end of the arrangement tray corresponds to the inlet hole, and a falling hole is provided on the arrangement tray corresponding to the outlet hole. The steam assembly is installed at the upper end of the cooking tank. One end of the conveying assembly corresponds to the outlet hole, and the other end of the conveying assembly penetrates through the spraying tank. The spraying assembly is installed inside the spraying tank; Step 2: Push the processed canned food into the steaming chamber of the steaming tank through the feeding hole, and the canned food is arranged neatly on the arranging tray in sequence. Step 3: During the movement of the canned food on the arranging tray, sterilize the canned food in the steaming chamber through the steam assembly installed at the top of the steaming tank. Step 4: After the canned food is sterilized when it moves to the falling hole, output the canned food through the discharging hole, and then convey the canned food to the spraying tank through the conveying assembly. Step 5: The canned food entering the spraying tank is subjected to step-by-step temperature reduction treatment through the spraying assembly.

[0006] When the processed canned food needs to be sterilized, the canned food enters the steaming tank through the feeding hole of the steaming tank. The canned food is received by the arranging tray when it enters the steaming tank. The canned food is arranged on the arranging tray according to the front-back order. Then, the steam assembly installed at the top of the steaming tank releases steam into the steaming chamber of the steaming tank to sterilize the canned food in the steaming chamber. Under the continuous feeding push at the feeding hole, when the front-end canned food entering the steaming chamber meets the qualified steaming time, it enters the discharging hole from the falling hole on the arranging tray and thus exits the steaming chamber. The canned food is received by the conveying assembly, and the conveying assembly drives the canned food through the spraying tank. Then, the spraying assembly in the spraying tank performs step-by-step temperature reduction treatment on the canned food to reduce the temperature of the canned food for subsequent packaging. The sterilization treatment of the canned food is completed, achieving the purpose of automatic feeding and discharging during the steaming and sterilization process.

[0007] Preferably, the falling hole is located at the center of the arranging tray. A guiding plate is installed on the arranging tray.

[0025] As Figure 7As shown, the conveying assembly 4 includes a transfer conveyor belt 41 and a guiding pipe 42. One end of the transfer conveyor belt 41 corresponds to the discharge hole 13, and the other end of the transfer conveyor belt 41 penetrates through the spraying tank 5. The guiding pipe 42 is disposed at one end of the transfer conveyor belt 41 corresponding to the discharge hole 13. Support frames 43 are provided on both sides of the transfer conveyor belt 41. One end of the support frame 43 corresponds to the transfer conveyor belt 41, and the other end of the support frame 43 is connected to the guiding pipe 42. One end of the guiding pipe 42 contacts the bottom surface of the cooking tank 1 and corresponds to the discharge hole 13, and the other end of the guiding pipe 42 contacts the transfer conveyor belt 41. The included angle between the guiding pipe 42 and the transfer conveyor belt 41 is an acute angle, and the cross-sectional shape of the guiding pipe 42 is semi-circular.

[0026] The spraying assembly 6 includes a heater 61 and a spraying pipe 62. The heater 61 is installed on the spraying tank 5, and the spraying pipe 62 is disposed inside the spraying tank 5. The shape of the spraying pipe 62 is spiral. One end of the spraying pipe 62 passes through the spraying tank 5 and communicates with the heater 61. The transfer conveyor belt 41 passes through the spraying pipe 62. A number of uniformly distributed spray heads 63 are installed on the spraying pipe 62, and all the spray heads 63 are located above the transfer conveyor belt 41.

[0027] An outflow hole 51 is provided at the bottom of the spraying tank 5 and communicates with the spraying pipe 62. A centralized tank 52 is provided at the lower end of the spraying pipe 62 and corresponds to the outflow hole 51. A water pump 53 is installed inside the centralized tank 52. A connecting pipe 54 is provided on the water pump 53. One end of the connecting pipe 54 communicates with the water pump 53, and the other end of the connecting pipe 54 communicates with the heater 61.

[0028] A sealing assembly 8 is installed inside the cooking cavity 11. The sealing assembly 8 includes a sealing plate 81 and a pneumatic cylinder 82. The sealing plate 81 corresponds to the feeding hole 12 and fits against the inner wall of the cooking cavity 11. A sliding block 83 is installed on one side of the sealing plate 81. A sliding groove 14 is provided on the inner wall of the cooking cavity 11. The sealing plate 81 is slidably connected to the cooking tank 1 through the cooperation of the sliding block 83 and the sliding groove 14. The pneumatic cylinder 82 is installed on the inner wall of the cooking cavity 11, and the pneumatic end of the pneumatic cylinder 82 is connected to the sealing plate 81.

[0029] An extension rod 15 is installed on the inner wall of the cooking cavity 11. A pneumatic cylinder 16 is installed on the extension rod 15, and a blocking block 17 is installed on the pneumatic cylinder 16. The blocking block 17 corresponds to the falling hole 31.

[0030] When the canned food needs to be sterilized by steaming, the canned food is conveyed by the feeding conveyor belt 33. The canned food enters the steaming chamber 11 from the feeding hole 12 and enters the interval between the guiding plates 32 on the arranging tray 3. Driven by the canned food that subsequently enters the steaming chamber 11, the canned food moves along the spiral line of the guiding plate 32 and is arranged on the arranging tray 3. During the movement of the canned food, the steam generator 23 on the closing cover 21 works to release steam into the steaming chamber 11, increasing the temperature in the steaming chamber 11, thereby performing steam sterilization treatment on the canned food. After the canned food in the arranging tray 3 is arranged, the pneumatic cylinder 82 pushes the sealing plate 81 to move along the sliding groove 14, thereby closing the feeding hole 12. Moreover, since the pneumatic cylinder 16 drives the blocking block 17 to close the falling hole 31, the airtightness of the steaming pot 1 is improved, and a better steaming and sterilization process is achieved.

[0031] During the steaming process, the internal state can be observed through the observation plate 26 on the closing cover 21. After the treatment is completed, the fixing of the fixing plate 75 can also be released by rotating the fastening nut 76 on the screw rod 73. Then, rotate the fixing plate 75 away from the opening and closing plate 7, and then rotate the opening and closing plate 7 through the pull ring 77 to open the opening hole 27 and then operate on the steaming chamber 11.

[0032] After the canned food in the steaming pot 1 is processed, the sealing plate 81 and the blocking block 17 retract, opening the feeding hole 13 and the falling hole 31. Then, driven by the subsequently entering canned food, the canned food that enters first comes into contact with the fitting plate 34 one by one, and then discharges through the falling hole 31 and the discharging hole 13 until the newly entered canned food fills the arranging tray 3. The canned food released from the discharging hole 13 enters the guiding pipe 42 and falls onto the transfer conveyor belt 41 under the guidance of the guiding pipe 42. Then, the transfer conveyor belt 41 drives the canned food to pass through the spray pipe 62. When the canned food passes through the spray pipe 62 in the spray tank 5, the spray heads 63 on the spray pipe 62 spray the canned food. Since the hot water generated by the heater 61 gradually cools down as it moves in the spray pipe 62, the canned food is subjected to step-by-step cooling and spraying treatment.

[0033] The water flowing out during the spraying process and the water flowing out from the end of the spray pipe 62 both flow from the outflow hole 51 to the centralized tank 52. Then, the water body is pumped by the water pump 53 installed in the centralized tank 52 and injected into the water inlet pipe of the heater 61 through the connecting pipe 54, thereby realizing the recycling of the water body.
