[0002] In the food processing industry, the internal circulation steaming equipment for scallion buns is a special device for steaming scallion buns. It achieves uniform distribution and efficient utilization of steam through internal circulation to ensure the steaming effect of scallion buns. At the same time, the internal circulation design reduces steam waste, improves energy utilization efficiency, and has a relatively high overall steaming efficiency.

[0003] Currently available internal circulation steaming equipment for scallion buns typically steams the semi-finished scallion buns by blowing steam from two steam vents on the left and right. However, due to the limited distance of the steam blowing, the steam may become unevenly concentrated or dispersed in the middle area during the actual steaming process. This uneven steam distribution affects the steaming effect of the scallion buns, resulting in uneven steaming of some products and reducing the efficiency of the equipment. Therefore, an internal circulation steaming equipment for scallion buns is proposed to address these issues. Utility Model Content

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] An internal circulation steaming device for scallion buns includes an insulated steamer 1, a water tank 2 at the bottom of the insulated steamer 1, a movable groove 7 deep inside the insulated steamer 1, a limiting chuck 10 fixedly connected to the inside of the movable groove 7, an auxiliary connecting shaft 21 passing through the central slot of the limiting chuck 10, a movable sleeve 9 fixedly connected to the auxiliary connecting shaft 21 in the gap between the upper and lower limiting chucks 10, a flow equalization plate 8 fixedly connected to the front end of the movable sleeve 9, a limiting back frame 11 fixedly connected to the rear of the top of the insulated steamer 1, a drive gear 12 fixedly connected to the outside of one end of the auxiliary connecting shaft 21 extending to the limiting back frame 11, a reciprocating rack 13 meshing with the front end of the drive gear 12, an electric push rod 15 fixedly installed on the right side inside the limiting back frame 11, and a door 19 rotatably connected to the front right side of the insulated steamer 1.

[0021] Support legs 6 are fixedly connected to the bottom left and right sides of water tank 2. Electric heaters 20 are fixedly installed at the lower front end of water tank 2. There are three electric heaters 20 in total, which facilitate the electric heating of the pure water inside water tank 2. Steam exhaust chambers 3, connected to the steam outlet of water tank 2, are fixedly installed on both the left and right sides of the interior of the insulated steam oven 1. The height of the steam exhaust chambers 3 is equal to the height of the internal working space of the insulated steam oven 1. Steam outlets 18 are located on opposite sides of the two steam exhaust chambers 3. Support strips 4, fixedly connected to the steam exhaust chambers 3, are located in the blank area between the upper and lower steam outlets 18. A steaming tray 5 is located above the support strips 4. The steaming tray 5 and the uniform flow plate 8 are vertically opposite each other. The support strips 4 provide auxiliary support for the steaming tray 5. Function: A circulating air pump 16, which is connected to the inside of the insulated steam oven 1, is fixedly connected to the top center position. The circulating air pump 16 is provided with circulating bends 17, which are connected to the inside of the steam discharge compartment 3, on the lower left and lower right sides. This structure facilitates the equipment to send the hot steam carried upward back into the interior of the insulated steam oven 1. The movable end of the electric push rod 15 is fixedly connected to the right longitudinal plate of the reciprocating rack 13. The left and right sides of the inner rear end face of the limiting back frame 11 are fixedly connected with guide bars 14, which are slidably connected to the left and right longitudinal plates of the reciprocating rack 13. The reciprocating rack 13 has a "U" shaped structure. The auxiliary connecting shaft 21 is set inside the movable groove 7 and rotatably connected to the insulated steam oven 1. The oscillating uniform flow structure formed by this structure is conducive to the equipment to perform auxiliary uniform flow treatment of hot steam and improve the overall steaming effect of the equipment.

[0022] Workflow: The electrical energy required for the equipment to start and run in this utility model comes from an external power source. Specifically, before use, the terminals of the three electric heaters, the electric push rod 15, and the circulating air pump 16 need to be connected to the main control module of the equipment. This main control module is also electrically connected to an external DC power supply to form a complete circuit system. Simultaneously, an appropriate amount of pure water needs to be pre-filled into the water tank 2. During the steaming of scallion buns, when using this internal circulation scallion bun steaming equipment, because an appropriate amount of pure water is pre-filled into the water tank 2, the external controller simultaneously controls the flow of pure water. Three electric heaters 20, extending from the hot end into the water tank 2, preheat the water first. After preheating for a period of time, the door 19 is opened by flipping it outwards. Connected to the steam exhaust chamber 3, a steaming tray 5 containing multiple semi-finished scallion buns can be pushed from front to back into the insulated steamer 1. Multiple sets of support strips 4 provide stable support to the tray 5 after it is pushed into place. The door 19 is then closed, keeping the interior of the insulated steamer 1 relatively sealed. As the electric heaters 20 continue heating, the pure water inside the water tank 2 is heated into hot steam. After entering the steam exhaust chamber 3, the steam is released through multiple steam outlets 18 towards… The inner middle area of ​​the insulated steam oven 1 is brought together to facilitate the diffusion of hot steam, processing the semi-finished scallion buns in the steaming tray 5. At this time, with the auxiliary connection of the movable groove 7 and the limiting back frame 11, the electric push rod 15 is activated by the external controller. Under the auxiliary guidance of the left and right guide bars 14, it reciprocates along the inner side of the limiting back frame 11, pushing the reciprocating rack 13. The drive gear 12, which cooperates with the reciprocating rack 13, will, through the auxiliary coupling 21, drive the movable sleeve 9 and the flow equalizing plate 8 to achieve a reciprocating oscillation operation, oscillating and equalizing the hot steam diffused inside the insulated steam oven 1, making it more efficient. Hot steam can evenly carry the central area, enabling the equipment to efficiently steam the semi-finished scallion buns. At the same time, the external controller starts the circulating air pump 16, which draws the hot steam that is evenly diffused inside the insulated steaming box 1 upwards, and then recirculates it into the steam discharge chamber 3 through the circulating bend pipe 17, and then carries it out from the steam outlet 18. This works in conjunction with the equipment to achieve the purpose of internal circulation steaming of the semi-finished scallion buns. Finally, after the specified steaming time is reached and after a period of cooling, the box door 19 is turned outwards and opened. Then, by pulling out the steaming tray 5, the steamed scallion buns are taken out, and the entire steaming operation is completed.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
