[0049] Furthermore, in step A, the eggs are poured into a cleaning and disinfection tank with a residual chlorine concentration of 200ppm. The eggs are submerged, and floating eggs are detected and isolated for treatment. The disinfection water is replaced every two hours to maintain the disinfection effect. This ensures that the eggs are clean and sterile, preventing them from affecting cake production.

[0050] Furthermore, in step B, first, weighed eggs, white sugar, trehalose, water, small ingredients, glycerin, cake oil, and codfish paste are poured into a clean mixing barrel 102 and stirred at 65 rpm; second, flour is poured into the mixture and simultaneously passed through a double-layer sieve 2 and stirred at 70 rpm until the batter is uniform; third, cake oil, sorbitol, and glycerin are poured into the mixture and stirred at 70 rpm; fourth, soybean oil and flavoring are poured into the mixture and stirred at 70 rpm until the slurry is uniform. Multi-stage stirring and stepwise addition of ingredients ensure a more uniform mixture.

[0051] Furthermore, in step C, the tunnel oven is divided into four baking zones: Zone 1, top heat 160°C ± 5°C, bottom heat 135°C ± 5°C; Zone 2, top heat 165°C ± 5°C, bottom heat 138°C ± 5°C; Zone 3, top heat 163°C ± 5°C, bottom heat 135°C ± 5°C; and Zone 4, top heat 166°C ± 5°C, bottom heat 133°C ± 5°C. Fine-tuning the baking temperature by zone ensures a more stable cake during baking.

[0052] Furthermore, the telescopic rod 2011 includes a support rod 2016 fixedly connected to the annular fixed disk 202 and a support block 2017 threadedly connected to the support rod 2016. A guide tapered strip 2018 is provided on the top of the support rod 2016. The threaded engagement of the support block 2017 and the support rod 2016 allows the support block 2017 to extend outward when the support block 2017 is rotated, thereby tightly abutting against the inner wall of the mixer 1 for fixation and facilitating disassembly. The guide tapered strip 2018 is also provided to prevent the powder from being placed on the support rod 2016 and forming a butt joint.

[0053] Furthermore, a connection block 2019 is threadedly connected to the connection point between the rotating connector 201 and the first connecting rod, and the connection block 2019 is fixedly connected to the first connecting rod 203. The rotating connector 201 can be replaced as needed to adapt to different connecting parts 101.

[0054] Furthermore, the mixer 1 includes a mixing barrel 102, a lifting base 103, a drive motor 104, and a stirring rod 105. The lifting base 103 is located below the mixing barrel 102, and the drive motor 104 is installed at the lifting end of the lifting base 103.

The lower end of the stirring rod 105 is provided with a transmission rod 108 that is rotatably placed in the guide tube 106. The transmission rod 108 is provided with a transmission thread 109. The transmission rod 108 is connected to the drive motor 104 in a transmission manner. A sealing ring is provided between the guide tube 106 and the transmission rod 108. The bottom of the mixing barrel 102 is tapered. Specifically, the transmission pipe 107 is connected to the feed pipe 1014 and the slurry delivery pipe 1015 respectively, and a transmission screw is installed in the transmission pipe 107. Electromagnetic valves are installed at the connection between the feed pipe 1014 and the slurry delivery pipe 1015 and the transmission pipe 107. When stirring, the transmission rod 108 is driven by the drive motor 104 to rotate in the opposite direction, thereby driving the stirring rod 105 to stir, and after the stirring is completed, when the slurry is delivered, the electromagnetic valves of the transmission pipe 107 and the slurry delivery pipe 1015 are opened, and the electromagnetic valve of the feed pipe 1014 is closed. The driving motor 104 is driven to rise by the lifting seat 103, and the stirring rod 105 is driven to rise by the transmission rod 108, thereby leaking out of the output port, so that the stirred slurry is input from the output port into the guide pipe 106 for transmission. At the same time, the transmission rod 108 can be driven by the drive motor 104 to rotate forward, and the transmission screw 109 is cooperated to feed the material downward. The slurry enters the transmission pipe 107 and cooperates with the transmission screw to move the material. The transmission is placed in the slurry delivery pipe 1015 for slurry delivery to realize automatic feeding, and the stirring rod 105 also rotates, so as to stir while transmitting to prevent precipitation due to long transmission time. When it is necessary to continue to transport liquid ingredients into the mixing barrel 102 during the stirring process, the electromagnetic valves of the transmission pipe 107 and the feed pipe 1014 are opened, and the electromagnetic valve of the slurry delivery pipe 1015 is closed. Then, the ingredients are transmitted through the transmission screw of the transmission pipe 107 and placed under the guide pipe 106. At the same time, the driving motor 104 drives the transmission rod 108 to rotate in the opposite direction, and cooperates with the transmission thread 109 to feed upward, so that the ingredient transmission is placed in the mixing barrel 102, and the slurry in the mixing barrel 102 will not flow out.

[0055] Furthermore, the stirring rod 105 includes a hollow tube 1010, an inner rod 1011, and a plurality of stirring blades 1012. The inner rod 1011 is placed in the hollow tube 1010 and fixedly connected to the inner wall of the hollow tube 1010. The inner rod 1011 and the transmission rod 108 are integrally formed. The plurality of stirring blades 1012 are equidistantly installed on the hollow tube 1010. A sealing sleeve 1013 is provided at the bottom of the hollow tube 1010. The sealing sleeve 1013 is interference-fitted with the guide tube 106. Specifically, the bottom of the stirring blade 1012 is fitted to the bottom of the mixing barrel 102. When feeding, the driving motor 104 is driven to rise by the lifting seat 103, and the inner rod 1011 is driven to push the hollow tube 1010 to rise through the transmission rod 108, so that the sealing sleeve 1013 is in the guide tube 106, so that the slurry flows into the guide tube 106, and at the same time the driving motor 104 is driven to rotate, thereby driving the inner rod 1011 through the transmission rod 108, and the inner rod 1011 drives the hollow tube 1010 to rotate, thereby driving multiple stirring blades 1012 to stir.

[0056] Furthermore, a guide rail 3 is provided above the mixer 1, on which a mobile vehicle 4 is movably mounted. A protective housing 5 is mounted on the mobile vehicle 4. A guide pipe 6 is rotatably mounted at the bottom of the protective housing 5. A rotating motor 7 is mounted within the protective housing 5 to drive the guide pipe 6. A telescopic hose 8 is mounted on one side of the protective housing 5 and is rotatably connected to and in communication with the guide pipe 6. When conveying powder, the motor 7 drives the guide pipe 6 to rotate, causing the powder to fall to different positions on the double-layer sifter 2, thereby preventing the powder from being conveyed to only one position, which may easily cause accumulation and affect the performance of the double-layer sifter 2.
