Description

Technical Field

[0001] The present invention relates to the technical field of bread fermentation, and more specifically, to a low-temperature energy-saving fermentation device for bread processing. Background Art

[0002] A bread fermentation device is a piece of equipment specifically designed to control and simulate a low-temperature fermentation environment. It provides a stable temperature and humidity environment, which helps the dough to ferment continuously at a lower temperature. The device can precisely control the temperature inside the fermentation chamber as needed. Low-temperature fermentation can extend the fermentation time, promote the complex fermentation process and flavor development of the dough. The ultimate result of dough fermentation is to increase the softness of the bread and improve the taste.

[0003] The existing patent publication number is CN118355932A, which discloses a bread blank fermentation device and method, relating to the technical field of bread processing. The technical solution is as follows: It includes a box body, and also includes a bearing part inserted into the chamber of the box body; a discharge port provided on the front side of the box body; a receiving part corresponding to the bearing part, the receiving part is located inside the box body and is arranged below the bearing part, and the front end of the receiving part is communicated with the discharge port. The receiving part can receive the fermented dough and output it to the discharge port; the bearing part includes a detection component, and the detection component can give feedback on the volume change during the dough fermentation. When the fermentation reaches the required volume, the bearing part discharges the dough to the receiving part. The beneficial effect of this invention is: It facilitates the staff to take the fermented bread blank, and also makes the bread fermentation process more precise. It not only avoids the time-consuming and laborious process of the staff pulling the fixed plate back and forth to confirm the bread fermentation situation, but also enhances the fermentation quality of the bread embryo, and has strong practicability.

[0004] Although this invention can enhance the fermentation quality of the bread embryo, there are still the following problems during the fermentation process:

[0005] 1. The device ferments the dough on multiple-layer trays. However, due to the lack of air circulation between the layers and the dough at the bottom being in contact with the trays, it is easy for low-temperature moisture to be difficult to circulate between the multiple-layer trays, and it is difficult for the bottom of the trays to be heated, resulting in uneven heating and thus affecting the fermentation effect.

[0006] 2. Dough fermentation produces carbon dioxide which fills the dough. If not released, it will affect the firmness of the bread. However, the existing device requires manual deflation after fermentation, which is time-consuming and laborious. Summary of the Invention

[0052] As an implementation manner of the present invention, the water spraying device 5 includes a water tank 51, the water tank 51 is installed outside the fermentation box 1, a stamping machine 52 is installed on the fermentation box 1, the stamping machine 52 is connected to the water tank 51, a water sprayer 53 is installed on the fermentation box 1 and the second star-shaped frame 22 through the fermentation box 1, and a heating rod 6 is installed on the water sprayer 53.

[0053] As an implementation manner of the present invention, a stop block 428 is rotatably connected on the first rack 418 and located in the "6" - shaped sliding groove 419. Example 1:

[0054] As Figure 1-5 shown, in this embodiment, the fermentation box 3 is rotated in the fermentation box 1 through the first star-shaped frame 21 and the second star-shaped frame 22, which can make the low-temperature moisture in the fermentation box 1 mix more evenly and improve the fermentation efficiency.

[0055] Start the stamping machine 52 to pressurize the water in the water tank 51 and spray it out through the water sprayer 53, so that the water is sprayed on the fermentation box 3 in the form of water mist, thereby evenly increasing the humidity of the dough. At the same time, the air in the fermentation box 1 is heated by the heating rod 6 to keep the temperature between 15 - 25 °C;

[0056] Start motor two 210 and motor three 215 simultaneously. Since the number of teeth of gear three 29 and gear six 214 is not completely and intermittently evenly distributed, gear three 29 drives star frame one 21 to rotate intermittently through gear two 28, and gear six 214 drives star frame two 22 to rotate intermittently through the multi-stage transmission between gear five 213, gear four 212, and gear ring two 211. Since the rotational speeds of motor two 210 and motor three 215 are the same, star frame one 21 and star frame two 22 are driven to rotate at the same speed intermittently at the same time.

[0057] It should be noted that the head of pawl one 216 is located between the teeth of gear two 28, the head of pawl two 217 is located between the teeth of gear five 213, and pawl one 216 and pawl two 217 are rotationally connected to the fermentation box 1 through torsion springs, so that pawl one 216 and pawl two 217 can only rotate in a single direction. Therefore, when gear two 28 and gear five 213 rotate in one direction, they push pawl one 216 and pawl two 217, and when rotating in the opposite direction, they are blocked by pawl one 216 and pawl two 217, thereby preventing gear three 29 from meshing with gear two 28 and gear six 214 from meshing with gear five 213, and preventing gear two 28 and gear five 213 from reversing due to the gravity of fermentation box 3.

[0058] Star frame one 21 drives fixed block one 23 to rotate around the center of star frame one 21. At the same time, since fixed block one 23 is rotationally connected to star frame one 21, and the fixed block one 23 on star frame one 21 and star frame two 22 is connected by a rotating shaft 24, and under the action of the gravity of the dough in fermentation box 3, when star frame one 21 and star frame two 22 rotate, the fermentation box 3 on fixed block one 23 always remains balanced and rotates around the center of star frame one 21, so that the dough in fermentation box 3 circulates to contact the low-temperature moisture in fermentation box 1, and the rotating fermentation box 3 increases the air circulation in fermentation box 1, improving the fermentation effect of the dough in fermentation box 3. Embodiment Two:

[0059] As Figure 1-16 shown, through the system set in fermentation box 1, after fermenting for a certain time, the dough in fermentation box 3 is regularly extruded to release gas and flipped by flipping mechanism 4, so that the bottom of the dough can also fully contact the low-temperature moisture, increasing the fermentation effect and improving the fermentation taste of the bread.

[0060] As Figures 6-7As shown, start the first motor 416 and drive the two turntables 411 to rotate synchronously through the belt 415. Since a first convex column 412 is fixedly connected to the outer ring of the turntable 411, and a second convex column 414 is fixedly connected to the sliding rod 49, and the first convex column 412 and the second convex column 414 are connected by a second connecting block 413, and the first convex column 412, the second convex column 414 and the second connecting block 413 are rotatably connected. Therefore, when the first convex column 412 rotates on the turntable 411, it drives the second connecting block 413 to move with it. Also, since the sliding rod 49 and the second convex column 414 can only move in the vertical direction, when the first convex column 412 rotates from top to bottom, it can drive the sliding rod 49 to move downward through the second connecting block 413, and when rotating from bottom to top, it can drive the sliding rod 49 to move upward, so that the sliding rod 49 slides up and down on the top of the fermentation box 1, and the sliding of the sliding rod 49 drives the first connecting block 41 to move up and down on the top of the fermentation box 1.

[0061] As Figure 1-4 shown, during the process of the first connecting block 41 moving up and down twice, when it first descends, the second rack 421 moves to the right, and the fermentation box 3 on the rotating block 43 is fixed to the fermentation box 3 on the first star-shaped frame 21; after the first connecting block 41 rises for the first time, the tooth shaft 42 rotates 180°, and drives the two mutually fixed fermentation boxes 3 to rotate 180° through the rotating block 43, realizing flipping, and flipping the dough in the fermentation box 3 on the first star-shaped frame 21 into the fermentation box 3 on the rotating block 43; after the second descent, the second rack 421 moves to the left and does not engage with the tooth shaft 42, and still makes the second rack 421 move to the left after the second rise, facilitating the extrusion and deflation of the dough in the fermentation box 3; the specific process is realized in the following way:

[0062] The process of the first connecting block 41 descending for the first time is as follows:

[0063] As Figures 7-10 shown, the first connecting block 41 moves downward, so that the third convex column 417 on the first connecting block 41 also moves downward, and slides downward through the inclined groove in the "6" - shaped sliding groove 419, and then pushes the first rack 418 to slide to one side. The first rack 418 drives the second rack 421 to slide in the opposite direction through the first gear 420. At the same time, the tooth shaft 42 on the first connecting block 41 moves to below the second rack 421 following the first connecting block 41. At the same time, as Figures 11-13As shown, the first cylinder 44 and the second cylinder 45 on the rotating block 43 enter into the circular hole plate 31 and the circular hole column 25. When the second cylinder 45 enters into the circular hole column 25, the slider 48 on the second cylinder 45 slides along the inclined chute 26 inside the circular hole column 25, causing the first cylinder 44 and the second cylinder 45 to rotate 45°. At the same time, since the bottom of the clamping block 46 is arc-shaped, when the first connecting block 41 drives the first cylinder 44 into the circular hole plate 31, the clamping block 46 moves towards the direction of the second spring 47 under the pressure of the edge of the circular hole plate 31. When it reaches the bottom of the circular hole plate 31, it slides out through the elastic force of the second spring 47 and gets stuck at the bottom of the circular hole plate 31, fixing the fermentation box 3. At this time, the clamping block 46 is between the two arc-shaped blocks 27. Because a spare fermentation box 3 was originally installed on one side of the rotating block 43 in this way, when the fermentation box 3 on the other side of the rotating block 43 is connected to the first star-shaped frame 21, the spare fermentation box 3 is fixed together with the fermentation box 3 on the first star-shaped frame 21. In this way, after the rotating block 43 reverses, the fermentation boxes 3 on both sides of the rotating block 43 will swap positions, making the fermentation box 3 on the first star-shaped frame 21 become the spare fermentation box 3.

[0064] At the same time, as Figure 7 , Figure 15 shown, since one end of the telescopic rod 427 is rotatably connected to the first connecting block 41, and the telescopic rod 427 is rotatably connected to the bottom of the fourth fixing block 422 on the side close to the first connecting block 41, when the first connecting block 41 descends, it drives the telescopic rod 427 to rotate, and by the lever principle, the other end of the telescopic rod 427 lifts the third rack 423 upwards. Since the toothed belt 425 meshes with the third rack 423 and the fourth rack 426, the upward movement of the third rack 423 drives the toothed belt 425 to rotate, and then drives the fourth rack 426 to move downwards. Since the distance between the first connecting block 41 and the fourth fixing block 422 of the telescopic rod 427 is shorter than the distance between the fourth fixing block 422 and the third rack 423, after the first connecting block 41 descends a certain distance, the fourth rack 426 moves downwards a large distance and enters the square hole 34, pushing the anti-sticking plate 33 inside the fermentation box 3 downwards, thereby squeezing carbon dioxide out of the dough in the fermentation box 3 on the first fixing block 23 through the anti-sticking plate 33 in the spare fermentation box 3, improving the fermentation effect.

[0065] The process of the first connecting block 41 rising for the first time is as follows:

[0066] As Figures 11-13 shown, the first connecting block 41 moves upwards, causing the slider 48 to rotate the first cylinder 44 and the second cylinder 45 by 45° again through the inclined chute 26. At this time, the clamping block 46 is still between the two arc-shaped blocks 27, so the circular hole plate 31 on the fermentation box 3 is still fixed by the clamping block 46 and moves upwards with the first connecting block 41. The clamping block 46 drives the two fermentation boxes 3 to move upwards. At the same time, as Figures 7-10As shown, the third convex post 417 is blocked by the stopper 428 and slides upward along the rightmost chute of the "6"-shaped chute 419. When the third convex post 417 moves to the connection of the rightmost inclined chute and the straight chute of the "6"-shaped chute 419, the third convex post 417 pushes the first rack 418 to continue moving to one side, and makes the second rack 421 continue to move in the opposite direction, and just can mesh with the gear shaft 42. The third convex post 417 on the first connecting block 41 continues to move upward along the straight chute of the "6"-shaped chute 419, keeping the second rack 421 in its current state. At the same time, the gear shaft 42 on the first connecting block 41 meshes with the teeth of the second rack 421 and rotates 180°, so as to drive the two mutually fixed fermentation boxes 3 to rotate 180° through the rotating block 43, realizing the flipping, and flipping the dough in the fermentation box 3 on the first star-shaped bracket 21 to the fermentation box 3 reserved on the rotating block 43. When the third convex post 417 slides along the upper right inclined chute, the third convex post 417 pushes the first rack 418 to make the second rack 421 move a certain distance to the left, so that the second rack 421 is disengaged from the gear shaft 42.

[0067] The process of the second descent is as follows:

[0068] As Figures 7-10 shown, the first connecting block 41 descends again, and the third convex post 417 moves downward along the straight chute in the middle of the "6"-shaped chute 419 until the lowest end of the straight chute, and drives the second rack 421 to move to the left and disengage from the gear shaft 42. At the same time, as Figures 11-13 shown, the slider 48 slides along the inclined chute 26, causing the first cylinder 44 and the second cylinder 45 to rotate 45°. During the rotation, the latch 46 in the first cylinder 44 is blocked by the arc-shaped block 27 and slides into the first cylinder 44, thus releasing the fixation of the latch 46 on the round hole plate 31, and further releasing the fixation of the reserved fermentation box 3.

[0069] The process of the second ascent is as follows:

[0070] As Figures 7-10 shown, the first connecting block 41 ascends again, and the third convex post 417 is blocked by the stopper 428 and returns to the initial state along the leftmost inclined chute of the "6"-shaped chute 419, and brings the fermentation box 3 on the first star-shaped bracket 21 after rotating 180° to the top of the fermentation chamber 1, restoring to the initial state.

[0071] It should be noted that the stopper 428 is rotationally connected to the first rack 418 through a torsion spring, so the stopper 428 will return to its original state every time it rotates; the time for the first connecting block 41 to move up and down twice is the same as the time for the first star-shaped bracket 21 and the second star-shaped bracket 22 to make intermittent movements and pauses.
