Description

Technical Field

[0001] The present invention belongs to the technical field of cake production, and particularly relates to a cake preparation process. Background Art

[0002] Cake is a relatively traditional pastry. It not only has a good flavor, but also has a soft texture and beautiful appearance, and is loved by consumers. The production of existing multi-layer cakes mainly relies on manual work. Especially, the cake stacking steps are all completed manually. Manual processing has defects such as high labor intensity and low production efficiency.

[0003] However, there are also many problems with existing cakes under an automated production line. For example, before the flour or white granulated sugar and other powdery materials are put into the mixer, they will be sieved to prevent caking and then put into the mixer. However, after sieving, they are piled up in the bucket and not put into the mixer in time. Due to gravity, the powdery materials at the bottom will still be compacted and caked. Therefore, when mixing, the bottom part still needs to be sieved again, resulting in a decrease in efficiency. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a cake preparation process that can sieve and mix at the same time to prevent the situation where the powdery materials at the bottom are caked and need to be sieved again.

Send the mold into the tunnel furnace for baking. E. Demold and cool. F. Inflate and package, and then pack into boxes. In step B, a double-layer sieve is installed inside the blender. The double-layer sieve includes a rotating connecting piece, an annular fixed disk, a first connecting rod, a rotating gear, a second connecting rod, a guiding track, a sliding support block, a first sieve plate, a sliding mounting piece, and a second sieve plate.

[0011] The mixer includes a mixing barrel, a lifting seat, a driving motor, and a mixing rod. The lifting seat is located below the mixing barrel. The driving motor is installed at the lifting end of the lifting seat. The mixing rod is rotatably placed inside the mixing barrel. A diversion pipe is provided at the bottom of the mixing barrel. An output port is provided at the bottom of the mixing barrel. The bottom of the mixing rod seals the output port. A transmission pipe is provided at the output port.

The transmission rod is in transmission connection with the driving motor. A sealing ring is provided between the diversion pipe and the transmission rod. The bottom of the mixing barrel is tapered.

[0012] The mixing rod includes a hollow pipe, an inner rod, and a plurality of mixing blades.

After stirring is completed, a lifting seat drives the driving motor to rise, and the transmission rod drives the stirring rod to rise so as to expose the output port, enabling the stirred slurry to be input into a diversion pipe through the output port for transmission. At the same time, the driving motor can drive the transmission rod to rotate, and cooperate with the transmission thread to feed downward to achieve automatic feeding.

[0018] 4. A cake preparation process of the present invention. When transmitting powder materials, a rotating motor drives a material guiding pipe to rotate, so that the powder materials fall to different positions of a double-layer sieve, preventing accumulation that is likely to occur when always transmitting to only one position and affecting the effect of the double-layer sieve.

[0021] In order to make the above features and advantages of the present invention more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.

[0022] As Figures 1 - 10 shown, this embodiment provides a cake preparation process, including the following steps: A. Wash, disinfect and shell the eggs, and pour them into the blender 1. B. Add ingredients, start the blender 1 to stir, and add flour during the stirring process, and the flour is sieved first and then enters the blender 1. C. After stirring, extract the slurry and pour it into the mold for shaping. D. Send the mold into the tunnel furnace for baking. E. Demold and cool. F. Inflate and package, and then pack into boxes. In step B, a double-layer sieve 2 is installed in the mixer 1. The double-layer sieve 2 includes a rotating connecting member 201, an annular fixed disk 202, a first connecting rod 203, a rotating gear 204, a second connecting rod 205, a guiding track 206, a sliding support block 207, a first sieve plate 208, a sliding mounting member 209, and a second sieve plate 2010. The stirring rod 105 of the mixer 1 is provided with a connecting portion 101 connected to the rotating connecting member 201. The two symmetric sides of the annular fixed disk 202 are respectively installed with telescopic rods 2011, and the ends of the telescopic rods 2011 respectively abut against the inner wall of the mixer 1. The first connecting rod 203 is installed on the rotating connecting member 201. The rotating gear 204 is installed on the first connecting rod and meshes with the inner ring teeth of the annular fixed disk 202. The second connecting rod 205 is installed on the rotating gear 204. The sliding support block 207 is rotatably installed on the second connecting rod 205 and is slidably connected to the guiding track 206. The guiding track 206 is fixedly installed on the annular fixed disk 202. The first sieve plate 208 is installed on the sliding support block 207. The sliding mounting member 209 is provided with a guiding groove 2012. A pushing block 2013 that cooperates with the guiding groove 2012 is provided at the connection between the second connecting rod 205 and the rotating gear 204. A guiding hole 2014 is provided below the guiding track 206. Guide rods 2015 that cooperate with the guiding hole 2014 are provided at the two symmetric ends of the sliding mounting member 209. The second sieve plate 2010 is installed on the sliding mounting member 209 and is located below the first sieve plate 208. Specifically, two hanging rings are provided on the annular fixed disk 202, and it is convenient to lift the double-layer sieve 2 through the hanging rings. By installing the double-layer sieve 2 in the mixer 1, the powder can be directly filtered into the mixer 1 for stirring after sieving, realizing sieving and stirring simultaneously, preventing the powder at the bottom from caking and requiring re-sieving. That is, the rotating connecting member 201 is connected to the stirring rod 105 of the mixer 1 for transmission. Thus, when the stirring rod 105 rotates, the rotating connecting member 201 rotates accordingly. Without connecting other driving motors, the rotating connecting member 201 will drive the first connecting rod 203 to swing. Thus, the rotating gear 204 cooperates with the annular fixed disk 202 to drive the second connecting rod 205 to rotate. At the same time, the second connecting rod 205 drives the sliding support block 207 to reciprocate along the guiding track 206, thereby pushing the first sieve plate 208 to reciprocate for sieving. At the same time, the pushing block 2013 cooperates with the guiding groove 2012 as the first connecting rod 203 swings to push the sliding mounting member 209 to reciprocate. Thus, the sliding mounting member 209 moves stably through the cooperation of the guiding hole 2014 and the guide rods 2015, and drives the second sieve plate 2010 to reciprocate for sieving, realizing double sieving.

[0023] Further, in step A, pour the eggs into the cleaning and disinfection pool with a residual chlorine concentration of 200 ppm, submerge the eggs, detect and isolate the floating eggs, and replace the disinfection water every two hours to maintain the disinfection effect. This makes the eggs clean and sterile, preventing them from affecting the production of the cake.

[0024] Further, in step B, first pour the weighed eggs, granulated sugar, trehalose, water, minor ingredients, glycerin, cake oil, and surimi into the clean mixing barrel 102 and stir at a speed of 65 rpm; second, pour in the flour while passing it through the double-layer sieve 2 and stir at a speed of 70 rpm until the batter is uniform; third, pour in the cake oil, sorbitol, and glycerin and stir at a speed of 70 rpm; fourth, pour in the soybean oil and essence and stir at a speed of 70 rpm until the slurry is uniform. Through multi-stage stirring and adding ingredients in batches, the mixing becomes more uniform.

[0025] Further, in step C, the tunnel oven is divided into four baking zones. In zone one, the upper heating is 160°C ± 5°C and the lower heating is 135°C ± 5°C; in zone two, the upper heating is 165°C ± 5°C and the lower heating is 138°C ± 5°C; in zone three, the upper heating is 163°C ± 5°C and the lower heating is 135°C ± 5°C; in zone four, the upper heating is 166°C ± 5°C and the lower heating is 133°C ± 5°C. Carry out zoning fine-tuning baking to make the cake more stable during baking.

[0026] Further, the telescopic rod 2011 includes a support rod 2016 fixedly connected to the annular fixed disk 202 and a top block 2017 threadedly connected to the support rod 2016. A diversion conical strip 2018 is provided at the top of the support rod 2016. Through the threaded cooperation between the top block 2017 and the support rod 2016, when the top block 2017 is rotated, the top block 2017 can extend outwards, so as to tightly abut against the inner wall of the mixer 1 for fixation, and it is also convenient for disassembly. And the diversion conical strip 2018 is provided to prevent the powder from forming a butt joint on the support rod 2016.

[0027] Further, a connecting block 2019 is threadedly connected to the connection part between the rotating connector 201 and the first connecting rod, and the connecting 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.

[0028] Furthermore, the blender 1 includes a mixing barrel 102, a lifting seat 103, a driving motor 104, and a mixing rod 105. The lifting seat 103 is located below the mixing barrel 102. The driving motor 104 is installed at the lifting end of the lifting seat 103. The mixing rod 105 is rotatably placed inside the mixing barrel 102. A diversion pipe 106 is provided at the bottom of the mixing barrel 102. An output port is provided at the bottom of the mixing barrel 102. The bottom of the mixing rod 105 seals the output port. A transmission pipe 107 is provided at the output port. A transmission rod 108 rotatably placed inside the diversion pipe 106 is provided at the lower end of the mixing rod 105. A transmission thread 109 is provided on the transmission rod 108. The transmission rod 108 is in transmission connection with the driving motor 104. A sealing ring is provided between the diversion pipe 106 and the transmission rod 108. The bottom of the mixing barrel 102 is conically arranged. Specifically, the transmission pipe 107 is respectively connected to a feed pipe 1014 and a slurry delivery pipe 1015. A transmission screw is installed inside the transmission pipe 107. Electromagnetic valves are installed at the connections between the feed pipe 1014 and the slurry delivery pipe 1015 and the transmission pipe 107. During mixing, the driving motor 104 drives the transmission rod 108 to rotate in the reverse direction to drive the mixing rod 105 to mix. And after mixing is completed, when slurry is delivered, at this time, the electromagnetic valve of the transmission pipe 107 and the slurry delivery pipe 1015 is opened, and the electromagnetic valve of the feed pipe 1014 is closed. The lifting seat 103 drives the driving motor 104 to rise, and the transmission rod 108 drives the mixing rod 105 to rise to expose the output port, so that the mixed slurry is input into the diversion pipe 106 from the output port for transmission. At the same time, the driving motor 104 can drive the transmission rod 108 to rotate in the forward direction, cooperating with the transmission thread 109 to feed downward. The slurry enters the transmission pipe 107 and cooperates with the transmission screw to transmit the material into the slurry delivery pipe 1015 for slurry delivery, realizing automatic feeding. And the mixing rod 105 also rotates, so as to mix while transmitting to prevent precipitation from forming due to too long transmission time. And when liquid ingredients need to be continuously fed into the mixing barrel 102 during the mixing process, at this time, 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 to the lower part of the diversion pipe 106 through the transmission pipe 107 and the transmission screw. And at the same time, the driving motor 104 drives the transmission rod 108 to rotate in the reverse direction, cooperating with the transmission thread 109 to feed upward, so that the ingredients are transmitted into the mixing barrel 102, and the slurry in the mixing barrel 102 will not flow out.

[0029] 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 inside the hollow tube 1010 and fixedly connected to the inner wall of the hollow tube 1010. The inner rod 1011 is integrally formed with the transmission rod 108. 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, and the sealing sleeve 1013 is in interference fit with the diversion tube 106. Specifically, the bottom of the stirring blade 1012 is in contact with the bottom of the stirring barrel 102. When feeding, the lifting seat 103 drives the driving motor 104 to rise, and the inner rod 1011 drives the hollow tube 1010 to rise through the transmission rod 108, so that the sealing sleeve 1013 moves away from the diversion tube 106, and thus the slurry flows into the diversion tube 106. At the same time, the driving motor 104 drives the rotation, and thus the inner rod 1011 is driven by the transmission rod 108. The inner rod 1011 drives the hollow tube 1010 to rotate, thereby driving the plurality of stirring blades 1012 to stir.

[0030] Furthermore, a guide rail 3 is provided above the mixer 1. A moving cart 4 is movably arranged on the guide rail 3. A protective box body 5 is installed on the moving cart 4. A material guide tube 6 is rotatably installed at the bottom of the protective box body 5. A rotating motor 7 for driving the material guide tube 6 to rotate is installed inside the protective box body 5. A telescopic hose 8 is installed on one side of the protective box body 5. The telescopic hose 8 is rotatably connected to the material guide tube 6 and is communicated therewith. When transmitting the powder material, the rotating motor 7 drives the material guide tube 6 to rotate, so that the powder material falls to different positions of the double-layer sieve 2, preventing the accumulation caused by always transmitting to only one position and affecting the effect of the double-layer sieve 2.
