[0002] The bun skin is a key part of making buns, and its taste and appearance directly affect the overall quality of the buns. Traditional fermentation of flour is an important step in making bun skin, which affects the taste, nutritional value and digestion and absorption of the pastries. Old dough fermentation refers to a small piece of dough left over from the last pastry making, which serves as an starter for the next pastry making. Compared with the yeast powder fermentation method, old dough fermentation has a unique taste of pastries, while pastries fermented with yeast powder will lack some unique taste and flavor.

[0003] At present, when making steamed bun wrappers, it is usually necessary to ferment and proof the dough for making the steamed bun wrappers. Before the dough is fermented, it is necessary to add old dough to new dough and mix them with water. Then, the mixed dough is placed in a fermentation device for fermentation and proofing. After the fermentation and proofing are completed, a part of the dough needs to be taken out to make old dough and stored for next use, which makes the pre-production process of the steamed bun wrappers more complicated.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing dough fermentation equipment on the market, and even if it can be solved, it needs to be solved through external tools, so it is impossible to achieve the desired effect.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1.

[0024] 2. In the process of processing old dough, the present invention can provide power to the transmission unit through the movement of the slide, so that the transmission unit drives the crankshaft to rotate, so that the knocking unit hits the slide, and at the same time the crankshaft presses the partition, so that part of the flour in the funnel falls on the slide, which can not only prevent the part of the old dough that is not completely dried inside from sticking to the slide, but also prevent the scraped old dough from sticking to the bottom of the slide, so as to improve the scraping and cutting effect of the scraping and cutting mechanism on the old dough.

[0047] As a further limitation of the scraping and cutting mechanism 3 of the present invention, the knocking unit 33 includes a cavity 3301 opened on one side of the inner cavity of the fermentation box body 1, and the interior of the cavity 3301 is rotatably connected with a crankshaft 3302, and the crankshaft 3302 is transmission-connected to the transmission unit 34, and the outer wall of the crankshaft 3302 is rotatably sleeved with a connecting rod 3303, and the connecting rod 3303 is transmission-connected to the funnel unit 35, and the bottom of the connecting rod 3303 is rotatably sleeved with an impact block 3304, and the bottom of the impact block 3304 passes through the cavity 3301; the knocking unit 33 can impact the slide plate 32, so that the slide plate 32 vibrates under the impact, so as to avoid the scraped old dough sticking to the bottom of the slide plate 32.

[0048] The transmission unit 34 includes a fixed rod 3401 fixedly installed inside the processing box 31, a sleeve 3402 is rotatably sleeved on the outer wall of the fixed rod 3401, and a transmission gear 3403 and a third gear 3405 are fixedly installed on both sides of the outer wall of the sleeve 3402, a tooth 3404 is provided on the rear side of the top of the slide plate 32, and the tooth 3404 is meshed with the transmission gear 3403, and a second synchronous belt 3406 is meshed on the outer wall of the third gear 3405, and a fourth gear 3407 is fixedly installed on the rear side of the outer wall of the crankshaft 3302. 06 extends into the interior of the cavity 3301, and one side of the second synchronous belt 3406 is meshed with the outer wall of the fourth gear 3407; the transmission unit 34 can transfer the kinetic energy generated by the movement of the slide plate 32 to the knocking unit 33, so that the knocking unit 33 plays a role in vibrating the slide plate 32. In addition, a partition is arranged on the front side of the transmission unit 34, and the partition is located between the teeth 3404 and the scraper surface 3201 to prevent old dough or flour from contacting with the teeth 3404, the transmission gear 3403, the third gear 3405, and the second synchronous belt 3406.

[0049] The funnel unit 35 includes a funnel 3501 opened on one side of the top of the processing box 31. The funnel 3501 is connected to the cavity 3301 and the processing box 31 respectively.

A first torsion spring 3503 is provided on the lower side of the interior of the funnel 3501. One side of the first torsion spring 3503 is in conflict with the inner wall of the funnel 3501, and the other side of the first torsion spring 3503 is in conflict with the bottom of the other side of the partition 3502; when the crankshaft 3302 rotates, the connecting rod 3303 will press one side of the partition 3502 to separate the other side of the partition 3502 from the inner wall of the funnel 3501, so that part of the flour can pass through the funnel 3501 and fall onto the slide plate 32, thereby preventing the part of the old dough that is not completely dried from sticking to the slide plate 32.

[0050] The support unit 36 ​​includes grooves 3601 opened on both sides of the bottom of the processing box 31, and a spring 3602 is fixedly installed at the bottom of the groove 3601.

[0051] In the process of scraping and cutting the old dough, the movement of the slide plate 32 can provide power to the transmission unit 34, so that the transmission unit 34 drives the crankshaft 3302 to rotate, so that the knocking unit 33 hits the slide plate 32, and at the same time the crankshaft 3302 presses the partition 3502, so that part of the flour in the funnel 3501 falls on the slide plate 32, which can not only prevent the part of the old dough that is not completely dried inside from sticking to the slide plate 32, but also prevent the scraped old dough from sticking to the bottom of the slide plate 32, so as to improve the scraping and cutting effect of the scraping mechanism 3 on the old dough.

[0052] The specific implementation of this embodiment is as follows: when the reciprocating unit 23 makes the slide plate 32 reciprocate laterally, the teeth 3404 on the slide plate 32 can drive the transmission gear 3403 to rotate, so that the transmission gear 3403 drives the sleeve 3402 to rotate on the fixed rod 3401, and the sleeve 3402 drives the third gear 3405 to rotate, and the third gear 3405 rotates the fourth gear 3407 through the second synchronous belt 3406, so that the fourth gear 3407 drives the crankshaft 3302 to rotate, so that the crankshaft 3302 drives the impact block 3304 to reciprocate longitudinally through the connecting rod 3303, so that the impact block 3304 plays the role of impacting the slide plate 32, and the slide plate 32 moves downward after being impacted, and the position of the slide plate 32 is supported by the spring 3602 and the push rod 3603, and the spring 3603 is used to support the slide plate 32. 02 has elasticity so that the slide plate 32 vibrates longitudinally. At the same time, when the crankshaft 3302 drives the connecting rod 3303 to rotate, the connecting rod 3303 can press one side of the partition plate 3502 to separate the other side of the partition plate 3502 from the inner wall of the funnel 3501, so that part of the new flour falls onto the slide plate 32. When the connecting rod 3303 passes over the position of the partition plate 3502, the first torsion spring 3503 drives the partition plate 3502 to reset and close the funnel 3501 to prevent the flour from continuing to fall. By sprinkling new flour on the slide plate 32 and vibrating the slide plate 32, the part of the old dough that is not completely dried can be prevented from sticking to the slide plate 32. In addition, through the setting of the transmission gear 3403, the crankshaft 3302 can be prevented from rotating in the opposite direction, thereby preventing the crankshaft 3302 and the partition plate 3502 from getting stuck.

[0057] The mixing unit 24 is used to mix the old dough, new flour and water into dough. When the bottom support 8 moves downward, after losing the top pressure of the support column 2403, the stirring rod 2402 tilts downward, and the dough hanging on the stirring rod 2402 can slide to the bottom support 8, so that the dough can be completely fermented and proofed on the bottom support 8, thereby eliminating the mixing work in the pre-making process of the bun skin.

[0058] The specific implementation of this embodiment is as follows: when the old dough and the new flour enter the mixing tank 6, the scraper 2401 can make the old dough and the new flour fall evenly on the bottom support 8, and play the role of flattening the old dough and the new flour. At the same time, the stirring rod 2402 stirs and fully mixes the old dough and the new flour. When the main shaft 22 rotates, the top ring 2404 rotates on the top of the support column 2403, which can prevent the support column 2403 from affecting the rotation of the main shaft 22. After adding water, the old dough and the new flour are mixed into dough. After the dough is mixed, the electric push rod 7 moves the bottom support 8 downward.

The dough on the tray 8 is then removed, and the old dough bin 4 on the hanging ring 12 is placed, part of the dough is placed in the old dough bin 4, and the plugs 51 are respectively set on the two ends of the old dough bin 4, and the plugs 53 are inserted into the inside of the slots 46. The plugs 53 press the baffle 41, so that the baffle 41 no longer closes the old dough bin 4, so that the two ends of the old dough bin 4 are ventilated, and dust and other impurities are prevented from entering the old dough bin 4 through the filter screen 52. In addition, a desiccant such as activated carbon can be added between the filter screens 52 on both sides of the plug 51 to absorb moisture, and then the old dough bin 4, that is, the plug 51, is simultaneously inserted into the inside of the fixing frame 5, and the fixing frame 5 is passed through the fixing frame 5. The positions of the old dough bin 4 and the plug 51 are stabilized, so that the dough can be ventilated and dried inside the old dough bin 4 to form old dough for next use. When the old dough is used, the old dough bin 4 is taken out from the fixing frame 5, and the plugs 51 at both ends are removed. After losing the support of the insert plate 53, the second torsion spring 42 drives the baffle plate 41 to reset to prevent the old dough from falling when the old dough bin 4 is picked up. Then, the old dough bin 4 is inserted from the top of the processing box 31, and the pressure column 43 is inserted into the old dough bin 4 and pressed downward, so that the pressure column 43 plays a role in pressing and holding the old dough, so as to press the old dough onto the slide plate 32 for processing.

[0060] S1: Take out the old flour bin 4 from the fixing frame 5, remove the plugs 51 at both ends, then insert the old flour bin 4 into the top of the processing box 31, and put the pressing column 43 into the top of the old flour bin 4, so that the pressing column 43 presses the old flour in the old flour bin 4 downward, and add some new flour into the funnel unit 35;

[0061] S2: The motor 21 and the electric push rod 7 are started by an external power supply and an external control device. The electric push rod 7 makes the bottom bracket 8 clamped on the bottom of the mixing tank 6. The scraping mechanism 3 is used to process the old flour through the transmission mechanism 2, so that the scraped old flour is introduced into the mixing tank 6. At the same time, the new flour is put into the mixing tank 6 inside the fermentation box body 1 through the upper hopper 11. The old flour and the new flour are fully mixed in the mixing unit 24, and then water is added to mix them.

[0062] S3: After the mixing unit 24 mixes the old dough and the new dough into dough, the external control device is used to start the electric push rod 7 to drive the bottom support 8 to move downward, and at the same time the stirring rod 2402 is drooped downward to prevent the dough from hanging on the stirring rod 2402, so that the dough is fermented and proofed in the fermentation box body 1;

[0063] S4: After the dough is fermented and proofed, the box door 10 is opened, and the box door 10 brings out the bottom support 8 through the linkage unit 9, then the old dough bin 4 on the hanging ring 12 is removed, and a portion of the dough is taken out and added to the old dough bin 4, and then the plugs 51 are respectively inserted on both sides of the old dough bin 4, and the old dough bin 4 and the plugs 51 are placed in the fixed frame 5 at the same time, so that the dough is ventilated and dried in the old dough bin 4 to make old dough for next use.
