Description

Technical Field

[0001] This utility model relates to the field of sandwich rice cake processing technology, specifically to a crack-resistant sandwich rice cake processing device. Background Technology

[0002] Rice cakes are made from sticky glutinous rice or rice flour. They are a traditional Chinese food and a seasonal food for the Lunar New Year. As the name suggests, filled rice cakes are rice cakes with fillings. The production of filled rice cakes requires the use of processing equipment.

[0003] For example, Chinese patent application CNCN202222830868.7 describes an extrusion device for processing rice cakes. This device includes a housing with two first electric push rods symmetrically fixed to its inner wall. Through this structure, a lead screw is installed inside the device, with a first motor at one end and a stirring rod fixedly connected to the other. Moving the stirring rod to the lower end of the rice cake facilitates stirring, making it easier to extrude through the forming discharge pipes. Three different forming discharge pipes are evenly arranged inside the housing. By extruding the rice cake, it is forced out through these pipes and dried by a hot air blower on the upper inner side of a protective plate, thus increasing the efficiency of the rice cake extrusion process.

[0004] However, in actual use, when the above-mentioned device is used to produce sandwich rice cakes, the sandwich rice cakes are extruded from the forming tube and then dried by the hot air blower. The internal temperature of the sandwich rice cakes cannot be raised, and the drying is uneven. This causes the temperature difference between the inside and outside of the sandwich rice cakes, which can easily lead to cracking on the surface, thereby reducing the production quality of the sandwich rice cakes and resulting in poor performance. Utility Model Content

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-8 As shown, this utility model provides a crack-resistant sandwich rice cake processing device, including a fixed frame 1 and a fixed frame 2 fixedly disposed on one front end of the fixed frame 1. A placement platform 5 is fixedly disposed on the bottom end of one side of the fixed frame 1. A drainage groove 13 is opened on the rear side of the bottom of the fixed frame 2 to facilitate the drainage of humidifying water overflowing from the fixed frame 1. A lead curtain 10 is fixedly disposed on the top front end of the fixed frame 2. An inclined plate 11 is fixedly disposed between the two side walls of the front end of the fixed frame 2. Several evenly distributed U-shaped support columns 15 are fixedly disposed at the bottom of the fixed frame 1 and the fixed frame 2 to facilitate the support of this utility model.

[0030] like Figure 1-3 As shown in Figure 5, the top of the fixed frame 2 is provided with a drying component 9, which is used to quickly dry the surface of the sandwich rice cake, lock in the moisture inside the sandwich rice cake, and prevent cracking. The drying component 9 includes a blower 91, which is fixedly installed on the top of the fixed frame 2. Two L-shaped connecting pipes 92 are fixedly installed at the air outlet of the blower 91. A horizontal pipe 93 is fixedly installed at the bottom end of each of the two L-shaped connecting pipes 92, and the two horizontal pipes 93 are respectively located on both sides of the fixed frame 2. Several evenly distributed ventilation pipes 94 are fixedly installed on the side of the horizontal pipes 93 near the fixed frame 2. A first small conveyor 3 and a second small conveyor 4 are fixedly installed inside the fixed frame 1 and the fixed frame 2, respectively. The ventilation pipes 94 pass through one side of the fixed frame 2 and are located on the top of the second small conveyor 4.

[0031] like Figure 1-4 As shown, a humidifying component 8 is fixedly installed on the top side of one side of the fixing frame 1 for humidifying the sandwich rice cake. The humidifying component 8 includes a top plate 81, which is fixedly installed on the top side of one side of the fixing frame 1 by four connecting columns 12. A water tank 82 is fixedly installed on the top of the top plate 81 by four supporting rods 83, and the top plate 81 is located on the top of the placement platform 5. A connecting pipe 84 is fixedly installed at the bottom of the water tank 82, and an electric valve 85 is fixedly installed on the connecting pipe 84. The bottom end of the connecting pipe 84 passes through the top plate 81 and is fixedly installed with a water collection frame 86. Several evenly distributed high-pressure nozzles 87 are fixedly installed at the bottom of the water collection frame 86, and the high-pressure nozzles 87 are interconnected with the interior of the water collection frame 86 to facilitate humidifying the surface of the sandwich rice cake and prevent cracking.

[0032] like Figure 1-3As shown in Figures 6 and 8, a pushing assembly 7 is fixedly provided at the rear end of one side of the fixed frame 1 for pushing the sandwich rice cake to move. The pushing assembly 7 includes a U-shaped support frame 71, which is fixedly provided on the rear wall of one side of the fixed frame 1. An electric push rod 73 is fixedly provided on the front side of the U-shaped support frame 71. An L-shaped push plate 72 is fixedly provided on the piston rod of the electric push rod 73, and the L-shaped push plate 72 is provided on the rear side of the top of the placement platform 5. A guide plate 6 is fixedly provided on the front side of the placement platform 5, and the guide plate 6 is provided on the top of the second small conveyor 4 to facilitate the L-shaped push plate 72 to push the sandwich rice cake to move. A photoelectric switch is embedded in the inner wall of one side of the fixed frame 1. The photoelectric switch is composed of a photoelectric sensor and a photoelectric receiver, and the photoelectric switch is provided on the top of the placement platform 5. A control panel 14 is fixedly provided on the front side of the fixed frame 1 for controlling the operation of the first small conveyor 3, the second small conveyor 4, the electric valve 85, the blower 91, the electric push rod 73, and the photoelectric switch.

[0033] By setting up the humidification component 8 and operating the control panel 14 to control the operation of the first small conveyor 3, the second small conveyor 4, and the electric valve 85, the sandwich rice cakes are placed sequentially on top of the first small conveyor 3. After being transported by the first small conveyor 3, they fall onto the top of the placement platform 5. The electric valve 85 is opened, allowing the humidifying water in the water tank 82 to enter the water collection frame 86 through the connecting pipe 84. Finally, the water is sprayed onto the sandwich rice cakes through several high-pressure nozzles 87, making the sandwich rice cakes moist and allowing the moisture to penetrate into the interior of the sandwich rice cakes, thereby preventing the sandwich rice cakes from cracking after processing. At the same time, the sandwich rice cakes (sandwiches) on the top of the placement platform 5 are detected by the photoelectric switch. When the rice cake enters the optical path between the photoelectric receiver and the photoelectric transmitter, it will block the light beam, causing the photoelectric receiver to be unable to receive the light signal. This indicates that the rice cake has been detected, meaning it has reached the top of the placement platform 5. Conversely, when the light beam is received by the photoelectric transmitter again, it indicates that the rice cake has not been detected. The through-beam photoelectric switch sends a signal to the control panel 14, causing the control panel 14 to control the electric push rod 73 to drive the U-shaped support frame 71 to push the humidified rice cake from the guide plate 6 to the top of the second small conveyor 4. When the through-beam photoelectric switch does not detect the rice cake, the control panel 14 controls the L-shaped push plate 72 to reset.

[0034] The control panel 14 controls the blower 91 to work. The blower 91 sends air into the horizontal pipe 93 through two L-shaped connecting pipes 92, and then blows the air into the fixed frame 2 through several ventilation pipes 94. The humidified rice cake falls onto the surface of the second small conveyor 4, which then transports it again. The air blown out through the ventilation pipes 94 can quickly dry the surface of the rice cake and lock in the moisture inside the rice cake, making it convenient for subsequent packaging or storage. This doubly prevents the rice cake from cracking, ensures the quality of the processed rice cake, and improves the processing effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
