[0059] The temperature of the second baking is preferably 110 - 130 °C, and the baking time is 34 - 46 min.

[0060] Referring to Figures 1 to 6 , the present invention further includes a slicing device and a blanking mechanism for the above-mentioned dry cake production process. Specifically, the slicing device includes a frame 10. Taking the length direction of the frame 10 as the left - right direction, a receiving channel 20 for docking with the discharge port 100 of the rotary cooling tower and a cutting channel 40 located below the receiving channel 20 are respectively arranged inside the frame 10. At the top of the right end of the frame 10, a guiding mechanism is provided which can move left - right and transfer the bread sent out from the discharge port 100 of the rotary cooling tower to the receiving channel 20. On one side of the receiving channel 20, a transfer mechanism 30 is also provided which can move up - down and transfer the cake received by the receiving channel 20 to the feed inlet of the cutting channel 40. And above the discharge port of the cutting channel 40, a slicing mechanism for slicing the cake is provided.

[0061] Referring to Figures 1 to 6 , the guiding mechanism includes a guiding track 101 arranged horizontally in the left - right direction. On one side of the guiding track 101, two movable guiding plates 102 are provided. On the side of the two guiding plates 102 facing the guiding track 101, guiding sliders 1021 that can move on the guiding track 101 are fixedly arranged. Driven by the guiding sliders 1021, the two guiding plates 102 can move left - right on the guiding track 101. On the side of the two guiding plates 102 facing each other, a vertically arranged guiding cylinder 103 is fixedly arranged. The output shaft of the guiding cylinder 103 is fixedly connected with a guiding push - plate 1031. The guiding push - plate 1031 is a long rectangular shape, and a number of first heat - dissipation holes 1032 arranged in a matrix are penetrated through the side surface of the guiding push - plate 1031.

[0062] Referring to Figures 1 to 6, when the rotary cooling tower starts to deliver bread, the two guide plates 102 drive the guide cylinder 103 and the guide push plate 1031 connected to the output shaft of the guide cylinder 103 to move to the top of the rotary cooling tower discharge port 100, and there is a gap between the two guide plates 102, then the output shaft of the guide cylinder 103 of the guide plate 102 located at the end of the rotary cooling tower discharge port 100 extends, driving the connected guide push plate 1031 to move downward to the top surface close to the rotary cooling tower discharge port 100, thereby playing the role of stopping the bread, and when a certain amount of bread is accumulated, the other guide plate 102 moves to the other side of the accumulated bread, and then the output shaft of the guide cylinder 103 on the guide plate 102 extends, driving the connected guide push plate 103 1 moves downward, at this time, the two guide push plates 1031 face each other and evenly contact the bread, achieving the effect of clamping the bread, then the two guide plates 102 move synchronously to above the receiving channel 20, thereby driving the bread clamped by the two guide push plates 1031 to move above the receiving channel 20, and then the two guide plates 102 move in opposite directions at the same time, thereby releasing the clamped bread and allowing the bread to fall into the receiving channel 20, and then repeating the above steps again. This can ensure the neatness of the bread and also save the step of manual material connection, reducing labor costs. At the same time, the first heat dissipation holes 1032 provided on the guide push plates 1031 can also prevent the bread from sticking to the bread when clamping it, avoiding damage to the surface of the bread when transferring the bread.

[0064] Reference Figures 1 to 7, at one end of the material receiving channel 20 far away from the discharge port 100 of the rotary cooling tower, there is a baffle 21, which is used to prevent the cakes from falling. Above the material receiving channel 20, there is a first pusher assembly that can be translated back and forth and can push the cakes stacked on the material receiving channel 20 into the above-mentioned accommodation space 34. The first pusher assembly includes a first cylinder 11 arranged in the front-back direction on the frame 10. The output shaft of the first cylinder 11 is fixedly connected with a vertically arranged first telescopic push plate. The first telescopic push plate includes a vertically arranged second cylinder 12 and a first horizontal plate 121 fixedly connected to the output shaft of the second cylinder 12. The first horizontal plate 121 is a long rectangle, and a number of third heat dissipation holes 1211 arranged in a matrix are opened on the side surface of the first horizontal plate 121. The third heat dissipation holes 1211 can prevent the situation of adhesion when pushing the bread, and avoid damaging the surface of the bread. When there are multiple cakes stacked on the material receiving channel 20, the output shaft of the second cylinder 12 extends to drive the first horizontal plate 121 to move downward to be parallel to the cakes, and then the output shaft of the first cylinder 11 extends to drive the second cylinder 12 to move forward, so as to push the cakes stacked on the material receiving channel 20 into the accommodation space 34 of the transfer box 33. After that, the first cylinder 11 and the second cylinder 12 are reset successively.

[0065] Refer to Figure 1 To Fig. 7, a second pusher assembly for pushing the cakes in the accommodation space 34 out of the accommodation space 34 is also provided at the lower right of the transfer mechanism 30. The second pusher assembly includes a third cylinder 13 horizontally arranged at the bottom of the frame 10 in the left-right direction. The output shaft of the third cylinder 13 is fixedly connected with a first push plate 131 for entering or exiting the above-mentioned accommodation space 34. When the transfer box 33 containing cakes moves to the cutting channel 40, the output shaft of the third cylinder 13 extends to drive the first push plate 131 to move into the accommodation space 34, so as to push the cakes into the feed port of the cutting channel 40.

[0066] Refer to Figures 1 to 7, above the above-mentioned cutting channel 40, there is a third pushing component that can move back and forth and push the cake pushed out by the second pushing component into the cutting channel 40. The third pushing component includes a second guide rail 41 arranged above the cutting channel 40 in the front-back direction. A movable second guide rail slider 411 is provided on the second guide rail 41. On the side of the second guide rail slider 411 facing away from the second guide rail 41, there is a vertically arranged second telescopic push plate. The second telescopic push plate includes a vertically arranged fourth air cylinder 42 and a second horizontal plate 421 fixedly connected to the output shaft of the fourth air cylinder 42. The second horizontal plate 421 is also a long strip rectangle, and a number of fourth heat dissipation holes 4211 arranged in a matrix are provided through the side surface of the second horizontal plate 421. The fourth heat dissipation holes 4211 can prevent the situation of adhesion when pushing the bread, which may cause damage to the surface of the bread. When the second pushing component pushes the cake in the above-mentioned accommodation space 34 into the cutting channel 40, the second guide rail slider 411 drives the second telescopic push plate to move to one side of the cake. Then the fourth air cylinder 42 extends to make the second horizontal plate 421 move downward to the same height as the cake. Then the second guide rail slider 411 drives the second telescopic plate to move towards the feed inlet of the cutting channel 40, so that the cakes are arranged in a row at the feed inlet of the cutting channel 40. Then the third pushing component resets.

[0067] Refer to Figures 1 to 10 , on the right side of the feed inlet of the cutting channel 40, there is also a fourth pushing component for pushing the cakes placed at the feed inlet into the interior of the cutting channel 40. The fourth pushing component includes a fifth air cylinder 14 arranged horizontally below the receiving channel 20 in the left-right direction. The output shaft of the fifth air cylinder 14 faces the cutting channel 40, and the output shaft of the fifth air cylinder 14 is also fixedly connected with a second push plate 141. The second push plate 141 is long strip-shaped. When the cake slicing in the cutting channel 40 is completed, the fifth air cylinder 14 extends to drive the second push plate 141 to move, so as to push the cake at the feed inlet of the cutting channel 40 into the cutting channel 40 for slicing.

[0068] Refer to Figures 1 to 10, above the cutting channel 40, there is a material transfer assembly that can move up and down and push the cake placed in the cutting channel 40 to translate in the direction of the slicing mechanism.

The output shaft of the sixth cylinder 441 faces the cutting channel 40, and the output shaft of the sixth cylinder 441 is fixedly connected with a material transfer plate 442 arranged in the front-back direction. There is a space for accommodating the cake between the two above-mentioned material transfer plates 442. During the cake slicing process, a row of cakes abuts against the material transfer plate 442 on the left side, and a row of cakes abuts between the two above-mentioned material transfer plates 442. When the slicing of the cake abutting against the side closer to the slicing mechanism is completed, the sixth cylinder 441 retracts, driving the material transfer plate 442 to move upward. At the same time, the material transfer frame 44 moves to the right. Then the sixth cylinder 441 extends to drive the material transfer plate 442 to move downward. At this time, the cake between the two above-mentioned material transfer plates 442 abuts against the material transfer plate 442 on the left side, and a row of cakes abuts again between the two above-mentioned material transfer plates 442. At the same time, the material transfer frame 44 will move in the direction of the slicing mechanism, so as to slice the cake.

[0069] Referring to Figures 1 to 12 , the above-mentioned slicing mechanism is arranged above the discharge port of the cutting channel 40 in a manner that can move up and down. When the cake passes through the slicing mechanism, it will fall in slices onto the feeding channel 50 arranged outside the discharge port of the cutting channel 40. In this embodiment, the slicing mechanism is an ultrasonic cutter 45. A first motor (not shown in the figure) is fixedly arranged on the frame 10 above the ultrasonic cutter 45. The output end of the first motor is connected with a crank-rocker mechanism (not shown in the figure). The output end of the crank-rocker mechanism is fixedly connected with the ultrasonic cutter 45. When the first motor is started, the ultrasonic cutter 45 is driven by the crank-rocker mechanism to perform reciprocating up and down motion, so as to slice the cake. Since both the ultrasonic cutter 45 and the crank-rocker mechanism are existing conventional technologies, no more details will be described here, and only a brief drawing is shown in the figure.

[0070] Referring to Figures 1 to 12, the feeding channel 50 is located below the discharge port of the cutting channel 40, and there is a spacing between the feeding channel 50 and the cutting channel 40. A retractable material receiving mechanism is also provided at the discharge port of the cutting channel 40. The material receiving mechanism is located above the spacing between the feeding channel 50 and the cutting channel 40. In this embodiment, the material receiving mechanism includes a seventh cylinder (not shown in the figure) provided at the bottom of the discharge port of the cutting channel 40. The output shaft of the seventh cylinder is fixedly connected with a material receiving plate 46. An inclined feeding hopper 47 is also provided at the bottom of the discharge port of the cutting channel 40. The feeding hopper 47 is located below the above-mentioned spacing. A collection box 48 for storing the heads and tails of the cakes is also provided below the feeding hopper 47. When the cake in the cutting channel 40 is cut to the tail, the ultrasonic cutter 45 temporarily stops moving. Then, the sixth cylinder 441 retracts to drive the material moving plate 442 to rise, and at the same time, the material moving frame 44 moves to the right. Then, the sixth cylinder 441 extends to drive the moving plate 442 to descend. The material moving frame 44 drives the ultrasonic cutter 45 to move in the reverse direction. At the same time, the seventh cylinder extends to drive the material receiving plate 46 to move onto the feeding channel 50. At this time, the spacing between the feeding channel 50 and the cutting channel 40 is not blocked. As the material moving frame 44 slowly moves towards the ultrasonic cutter 45, a new cake then moves below the ultrasonic cutter 45. At this time, the tail of the upper row of cakes is pushed into the spacing and enters the collection box 48 through the feeding hopper 47. Then, the ultrasonic cutter 45 starts again to slice the cake. The head of the cake will also fall into the spacing and enter the collection box 48 through the feeding hopper 47. Then, the seventh cylinder retracts to drive the material receiving plate 46 to move above the spacing, and the ultrasonic cutter 45 starts slicing and processing. This move is to ensure that the size of the sliced cakes is uniform and consistent.

[0071] Refer to Figures 1 to 13, at one end of the feeding channel 50 far from the discharge port of the cutting channel 40, there is a tray conveying channel 60 arranged in the front-rear direction. The tray conveying channel 60 is perpendicular to the feeding channel 50, and there are also a plurality of trays 61 moving along the conveying direction of the tray conveying channel 60 flowing on the tray conveying channel 60. The tray 61 is used to hold the sliced cakes. On the side of the tray conveying channel 60 far from the feeding channel 50, there is also a discharge channel 70 arranged in the left-right direction. The discharge channel 70 and the feeding channel 50 are arranged in a straight line. On the above-mentioned frame 10, there is also a blanking mechanism that can be translated left and right and can suck up the sliced cakes conveyed on the feeding channel 50 and transfer them to the tray 61. The blanking mechanism includes a fourth guide rail (not shown in the figure) arranged above the feeding channel 50 and the tray conveying channel 60. The fourth guide rail is arranged on the front and rear sides of the frame 10 in the left-right direction, and there is also a movable plate 51 on the fourth guide rail. At both ends of the side of the movable plate 51 facing the fourth guide rail, there are also fixed fourth guide rail sliders (not shown in the figure) that can move on the fourth guide rail. The movable plate 51 can be moved left and right on the fourth guide rail by the drive of the fourth guide rail slider. On the side of the movable plate 51 facing the feeding channel 50 and the sheet conveying channel 60, there is an air storage tank 53. On the side of the movable plate 51 facing away from the air storage tank 53, there are also an eighth cylinder (not shown in the figure) and an air connection port 52 for connecting to an external air source. In this embodiment, the external air source is a vacuum pump (not shown in the figure). The output shaft of the eighth cylinder passes through the movable plate 51 and is connected to the air storage tank 53. On the side of the air storage tank 53 facing away from the movable plate 51, there are also a plurality of suction cups 531 arranged in a matrix for sucking cakes. The above-mentioned air connection port 52 passes through the movable plate 51 and is communicated with the air storage tank 53 to provide suction force for the suction cups 531.

[0072] Refer to Figures 1 to 13 , at one end of the feeding channel 50 close to the tray conveying channel 60, there is also a pushing mechanism that can be telescoped left and right and can push the tray 61 loaded with cakes from the tray conveying channel 60 into the discharge channel 70. The pushing mechanism includes a ninth cylinder (not shown in the figure) arranged at the bottom of the feeding channel 50. The output shaft of the ninth cylinder is connected to a push block (not shown in the figure) for abutting against the tray 61. When the output shaft of the ninth cylinder extends towards the tray conveying channel 60, the push block moves accordingly and pushes the tray 61 loaded with cakes towards the discharge channel 70. When the tray 61 enters the discharge channel 70, the output shaft of the ninth cylinder retracts, and the push block also resets accordingly.

[0073] Refer to Figures 1 to 13When slicing the sliced cake, first the fourth guide rail slider drives the movable plate 51 to move on the fourth guide rail, so that the air storage box 53 is located above the feeding channel 50, and then the output shaft of the eighth cylinder extends, driving the air storage box 53 to move downward, and then the vacuum pump is turned on to make the suction cup 531 suck up the sliced cake, and then the output shaft of the eighth cylinder retracts, and the fourth guide rail slider drives the movable plate 51 to move above the tray 61 of the tray conveying channel 60, and then the output shaft of the eighth cylinder extends, the vacuum pump is turned off, and the cake adsorbed on the suction cup 531 falls into the tray 61, then the ninth cylinder extends, and the push block moves accordingly, and then the tray 61 is pushed into the discharge channel 70, and the worker puts the tray 61 with the cake on the rack for secondary baking, and the cake slicing process is completed.

[0074] The present invention provides a production process for dry cakes. By adopting a secondary baking method, the dry cakes obtained by the production process not only retain the sweetness of cakes but also have the crisp taste of biscuits. The present invention also provides a slicing device and a material placing mechanism for the production process. The slicing device can slice the cakes evenly without generating cake crumbs, and the material placing mechanism can automatically place the sliced cakes into a material tray, thereby greatly improving the cake slicing efficiency.

[0075] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
