Description

Technical Field

[0001] This utility model relates to the field of steaming and cooking equipment, specifically a steaming and cooking equipment for the production and processing of zongzi (sticky rice dumplings). Background Technology

[0002] Steaming in the production and processing of zongzi refers to the process of placing the zongzi wrapped with fillings into a steamer or pot and heating them with hot steam or hot water to cook them. The purpose of steaming is to ensure that the rice grains inside the zongzi are thoroughly cooked, the fillings are well integrated, and the texture is soft and sticky to the ideal degree. Through steaming, zongzi can have a unique taste while ensuring that its nutrients are well preserved.

[0003] According to the utility model patent application CN218073418U, a steaming and cooking device for making zongzi (sticky rice dumplings) is disclosed. The device includes a steaming cylinder, a sealing cover, and a steaming mechanism. The sealing cover is connected to the top of the steaming cylinder, and the steaming mechanism is detachably connected to the upper end of the sealing cover. The steaming mechanism consists of a steaming cage, a rotating device, and a cooling mechanism. The steaming cage is detachably connected to the bottom end of the rotating device, and the cooling mechanism is connected to the top of the steaming cage.

[0004] While this equipment facilitates the rotation of the rice dumplings during steaming, ensuring even heating and improving texture, it also allows for rapid cooling after steaming, facilitating collection and increasing efficiency. However, different types of rice dumplings require different cooking temperatures. Therefore, steaming all types at the same temperature will inevitably affect the cooking of some dumplings and the overall quality. To address these issues, we provide a rice dumpling production and processing steaming equipment. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a steaming and cooking device for the production and processing of zongzi (sticky rice dumplings).

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steaming and cooking device for producing and processing zongzi (sticky rice dumplings), comprising a base frame, a steaming chamber fixedly connected to the outer surface of the base frame, a steaming mechanism provided on the outer side of the steaming chamber, the steaming mechanism comprising two movable plates, each of the two movable plates having a fixed plate fixedly connected to its adjacent side, the outer surface of each fixed plate being slidably connected to the inner wall of the steaming chamber, a dual-axis servo motor fixedly connected to the upper surface of the base frame, two screws fixedly connected to the output end of the dual-axis servo motor, a movable frame threadedly connected to the outer surface of each screw, the top end of each movable frame being slidably connected to the inner wall of the steaming chamber, the bottom surface of each movable plate being fixedly connected to the upper surface of the movable frame, a partition plate fixedly connected to the inner wall of the steaming chamber, a shelf fixedly connected to the adjacent side of the two fixed plates, two air inlet pipes fixedly connected to the left side of the steaming chamber, and a valve fixedly connected to the outer surface of each air inlet pipe.

[0007] Furthermore, two positioning blocks are fixedly connected to both sides of the base frame, and each positioning block has a positioning hole on its upper surface.

[0008] Furthermore, two reinforcing blocks are fixedly connected to both sides of the cooking chamber, and the bottom surface of each reinforcing block is fixedly connected to the upper surface of the base frame.

[0009] Furthermore, two temperature sensors are fixedly connected to the upper surface of the cooking chamber, and the bottom end of each temperature sensor penetrates through the cooking chamber and extends into the interior of the cooking chamber.

[0010] Furthermore, the upper surface of the cooking chamber is fixedly connected to two air outlet pipes, and a safety valve is fixedly connected to the top of each air outlet pipe.

[0011] Furthermore, each of the two screws has a support plate rotatably connected to its opposite end, and the bottom surface of each support plate is fixedly connected to the upper surface of the base frame.

[0012] Furthermore, sealing gaskets are fixedly connected to the sides of the two fixed plates that are close to each other, and the sides of the two sealing gaskets that are close to each other are in contact with the front and back of the cooking chamber, respectively.

[0013] Furthermore, a flange is fixedly connected to the left end of each of the intake pipes, and six bolts are threaded onto the inner wall of each flange.

[0014] Compared with existing technologies, this steaming and cooking equipment for producing and processing zongzi (sticky rice dumplings) has the following advantages:

[0015] This invention utilizes a dual-axis servo motor to drive a screw, which in turn moves the movable frame, thereby moving the movable plate and the fixed plate. The racks on both sides allow for flexible movement of the rice dumplings, enabling different types of rice dumplings to be transported to the steaming chamber for cooking. This addresses the different temperature requirements of various types of rice dumplings, preventing some from being affected by uniform placement. The partitions further divide the steaming space, facilitating more precise control over the steaming environment for different types of rice dumplings. The combination of the air inlet pipe and valves allows for easy adjustment of the gas entering the steaming chamber. For example, the input of steam and other gases can be controlled according to the temperature requirements of different types of rice dumplings, thus better meeting the steaming requirements of different rice dumplings, improving the quality of rice dumplings, ensuring that each rice dumpling completes the steaming process under suitable conditions, and greatly enhancing the stability of product quality.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] This embodiment provides a steaming and cooking device for the production and processing of zongzi (sticky rice dumplings). This device is used to separate the zongzi for steaming and cooking according to their difficulty of steaming and cooking.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A steaming and cooking device for producing and processing zongzi (sticky rice dumplings) includes a base frame 1. A steaming chamber 2 is fixedly connected to the outer surface of the base frame 1. A steaming mechanism 3 is provided on the outer side of the steaming chamber 2. The steaming mechanism 3 includes two movable plates 301. Two positioning blocks 310 are fixedly connected to both sides of the base frame 1. Each positioning block 310 has a positioning hole 311 on its upper surface. This structural design helps to accurately position the device through the positioning hole 311, such as screws and positioning pins, when installing the device or connecting it with other components. This ensures the stability of the device during operation and prevents the device from shifting due to vibration or other reasons during the steaming and cooking of zongzi, thereby affecting the steaming effect and the service life of the device.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Two moving plates 301 are fixedly connected to fixed plates 302 on their sides that are close to each other. Two reinforcing blocks 313 are fixedly connected to both sides of the cooking chamber 2. The bottom surface of each reinforcing block 313 is fixedly connected to the upper surface of the base frame 1. The presence of the reinforcing blocks 313 can enhance the connection strength between the cooking chamber 2 and the base frame 1. When the cooking equipment is running, especially when the cooking chamber 2 is full of steam and may have a certain pressure, the reinforcing blocks 313 can prevent the cooking chamber 2 from shaking or tilting relative to the base frame 1.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Each fixed plate 302 has its outer surface slidably connected to the inner wall of the steaming chamber 2. A dual-axis servo motor 305 is fixedly connected to the upper surface of the base frame 1. Two screws 306 are fixedly connected to the output end of the dual-axis servo motor 305. Two temperature sensors 314 are fixedly connected to the upper surface of the steaming chamber 2. The bottom end of each temperature sensor 314 penetrates through the steaming chamber 2 and extends into the interior of the steaming chamber 2. The temperature sensor 314 can monitor the temperature inside the steaming chamber 2 in real time. During the steaming process of zongzi production and processing, different zongzi raw materials and processing technology may require specific steaming temperatures. The temperature sensor 314 can promptly provide temperature information so that the operator can adjust the steaming conditions according to the actual situation. At the same time, a sealing ring is provided at the penetration connection between the temperature sensor 314 and the steaming chamber 2 to increase the sealing effect of the gap between the two.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4Each screw 306 has a threaded connection to a movable frame 307 on its outer surface. The top of each movable frame 307 is slidably connected to the inner wall of the cooking chamber 2. The upper surface of the cooking chamber 2 is fixedly connected to two steam outlet pipes 315. The top of each steam outlet pipe 315 is fixedly connected to a safety valve 316. During the cooking process, a large amount of steam will be generated in the cooking chamber 2. The steam outlet pipes 315 provide a channel for the steam to be discharged, preventing the pressure inside the cooking chamber 2 from being too high. The safety valve 316 is opened by high-pressure steam to release pressure. There is a valve disc inside the safety valve 316, which is pressed on the valve seat by the action of a spring. When the pressure inside the chamber is lower than the set pressure, the spring force is greater than the steam pressure, and the valve is closed. When the internal pressure exceeds the set pressure, the steam pressure overcomes the spring force or the counterweight force and opens the valve disc, thereby releasing pressure and preventing the pressure inside the chamber from continuing to rise, ensuring safety.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom surface of each movable plate 301 is fixedly connected to the upper surface of the movable frame 307. The inner wall of the cooking chamber 2 is fixedly connected to a partition plate 309. The ends of the two screws 306 that are far apart from each other are rotatably connected to a support plate 312. The bottom surface of each support plate 312 is fixedly connected to the upper surface of the base frame 1. The support plate 312 provides support for the screws 306. When the dual-axis servo motor 305 drives the screws 306 to rotate, the screws 306 will bear a certain axial force and radial force. The support plate 312 can share these forces and prevent the screws 306 from bending or being damaged due to uneven force. The dual-axis servo motor 305 is a servo motor with two independent control axes, which can simultaneously control two different rotation directions or positions.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Each of the two fixed plates 302 has a shelf 308 fixedly connected to one side that is close to each other, and a sealing gasket 317 fixedly connected to one side that is close to each other. The two sealing gaskets 317 are in contact with the front and back of the steaming box 2 respectively. The sealing gasket 317 can effectively prevent steam leakage in the steaming box 2. When steaming zongzi, the steaming box 2 needs to maintain a certain steam pressure and temperature. If there is steam leakage, it will not only affect the steaming effect of zongzi, but also cause energy waste.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4Two air inlet pipes 303 are fixedly connected to the left side of the cooking chamber 2. Each air inlet pipe 303 has a valve 304 fixedly connected to its outer surface. Each air inlet pipe 303 has a flange 318 fixedly connected to its left end. Each flange 318 has six bolts 319 threadedly connected to its inner wall. The structure of the flange 318 and bolts 319 facilitates the connection of the air inlet pipe 303 to an external air source or other pipes. Through the cooperation of the flange 318 and bolts 319, the air inlet pipe 303 can be firmly connected, preventing the connection between the air inlet pipe 303 and the external equipment from loosening due to steam pressure or other reasons during the cooking process. This ensures that steam can stably enter the cooking chamber 2 through the air inlet pipe 303.

[0030] Working Principle: In use, the operator first connects the dual-axis servo motor 305 and temperature sensor 314 to the power supply to ensure stable power. Then, the operator turns on the dual-axis servo motor 305, causing it to rotate at both ends. The dual-axis servo motor 305 provides power output, driving the two screws 306 to rotate. When the screws 306 rotate, the threadedly connected movable frame 307 moves accordingly, causing the movable plate 301 and fixed plate 302 to move, which in turn moves the shelf 308. After the two shelves 308 have moved out, the operator sorts the easily cooked and difficult-to-cook rice dumplings and places them into the shelves 308 on both sides. Finally, the dual-axis servo motor 305 is used again to reset the shelves 308. In the steaming chamber 2, steam is supplied through an external steam pipe connected to the air inlet pipe 303 via a flange 318. Steam is then delivered and the temperature sensor 314 is activated. The temperature sensor 314, fixedly connected to the upper surface of the steaming chamber 2, can sense the internal temperature of the steaming chamber 2 to better control the steaming process. At the same time, the temperature sensed by the temperature sensor 314, combined with the cooking time of the zongzi, is used to control the opening and closing of the air inlet pipe 303 via the control valve 304, thereby facilitating the control of the amount of steam delivered. This avoids the situation where the steaming of some zongzi is affected due to different requirements for steaming temperature when placed uniformly. The partition plate 309 further divides the steaming space, which helps to more accurately control the steaming environment of different types of zongzi.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
