Description

Technical Field

[0001] The present invention relates to the technical field of pastry processing, in particular to a forming device for puff pastry and a production process. Background Art

[0002] Puff pastry is widely popular for its unique taste and rich layers; however, the traditional production process of puff pastry usually relies on manual operation, which is not only inefficient but also difficult to maintain consistency in product quality; with the continuous growth of market demand, the demand for automated puff pastry forming equipment that can produce efficiently and stably is becoming increasingly urgent.

[0003] After searching, the Chinese patent with publication number CN115299474A discloses a new pastry forming device. However, when the solution is actually used, it still has the following shortcomings:

[0004] Although most of the existing pastry forming equipment can operate at different speeds according to actual needs, the pastries need to be kneaded during the forming process. When the production speed increases, the residence time of the pastry dough in the kneading area is forced to be shortened. Since the kneading speed cannot be accelerated synchronously, the pastry dough cannot be fully kneaded, resulting in poor forming effect. The pastry dough that has not been fully kneaded is prone to irregular shape, loose internal structure and other problems during subsequent stamping and forming, which seriously affects product quality. On the contrary, when the production speed decreases, although the kneading time is relatively sufficient in theory, the mismatch between the slow conveying speed and the fixed kneading speed will cause the pastry dough to accumulate in the kneading area, increasing the risk of adhesion and even damaging the equipment.

[0005] Therefore, a kind of puff pastry forming equipment and production process are proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that although the existing pastry forming equipment in the prior art can work at variable speed, the kneading speed cannot be adjusted synchronously when the production speed changes; when the production speed is increased, the pastry dough is not kneaded sufficiently and the forming is poor; when the speed is reduced, the pastry dough is easily piled up and adhered; this seriously affects the product quality and the operation of the equipment.

[0018] A process for preparing shortcrust pastry using a forming device comprises the following steps:

[0019] S1. Equipment preparation and material delivery: The mixed pastry dough is conveyed to the entrance of the forming equipment body through a conveyor belt, ready for subsequent processing steps;

[0020] S2, kneading and shaping: Start the motor and drive the speed change component, so that the active roller and the driven roller drive the kneading belt to transmit in the opposite direction. After the pastry dough enters between the two kneading belts, it is subjected to the reverse force of the kneading belts and is kneaded evenly into the specified shape. During the kneading process, the adjustment component automatically adjusts the tension of the kneading belt according to the kneading speed to ensure the consistency of the kneading effect.

[0021] S3, stamping and forming: The kneaded pastry dough is conveyed by the forming equipment body into the stamping area, and the stamping device stamps and forms the kneaded pastry dough according to the pre-set mold shape to form a puff pastry blank with a specified shape;

[0022] S4, collection and storage: The puff pastry blanks after punching are conveyed to a collection area via a conveyor belt and stored.

[0023] Technical effects and advantages of the present invention:

[0024] In the present invention, the two kneading belts are driven by the active roller and the driven roller to transmit in reverse, and a closed kneading area is formed in conjunction with the fence. When the pastry dough is sent into the area by the conveyor belt, it is quickly shaped in the process of rolling and extrusion by the friction of the two kneading belts running in reverse, forming a blank with a smooth surface and uniform density. The structure is driven to rotate by the speed change drive mechanism through the active roller, and the friction force on the inner side of the kneading belt drives the driven roller to rotate in the reverse direction. According to the requirements of the subsequent stamping mold, the kneading belt transmission speed can be changed by adjusting the first screw, so that the size of the blank can be accurately matched with the stamping process, and the molding waste caused by uneven kneading can be effectively reduced.

[0025] In the present invention, the kneading belt is driven to rotate by the motor through the first conical wheel, the second conical wheel and the first driving belt. The position of the driving belt can be adjusted by rotating the first screw through the driving plate to achieve the matching of the rotation speed with the conveying speed; at the same time, the worm, worm wheel and forward and reverse screws are linked to the driving column to adjust the position of the auxiliary roller, and the tension of the kneading belt is adaptively adjusted to avoid slipping at high speed or excessive wear at low speed.

[0026] In the present invention, the first rotating shaft drives the second screw to rotate through a double-row pulley and a second driving belt, and the extrusion column periodically squeezes the inclined block, so that the edible oil in the storage box is sprayed to the kneading belt through the atomizing nozzle; at the same time, the scraping strip is close to the surface of the kneading belt to remove residual pastry dough, reduce adhesion and reduce friction loss, thereby ensuring product hygiene and equipment service life.

DETAILED DESCRIPTION

[0038] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0039] Reference Figure 1 - Figure 9 As shown, the present invention provides a technical solution: a forming device for puff pastry, comprising a forming device body 1, a kneading mechanism installed on the forming device body 1, the kneading mechanism comprising a fence 602 fixedly mounted on the forming device body 1, two fences 602 are each provided with a kneading belt 604, the kneading belt 604 is internally provided with a driving assembly, the two driving assemblies control the two kneading belts 604 to drive in opposite directions, and knead and convey the pastry entering between the two kneading belts 604;

[0040] Two support plates 2 are fixedly mounted on the top of the molding equipment body 1, and a variable speed drive mechanism is fixedly connected to the top of the support plate 2. The variable speed drive mechanism controls the two drive components to drive the two kneading belts 604 in opposite directions.

[0041] An adjustment mechanism is provided inside the speed-changing drive mechanism. When the speed-changing drive mechanism controls the transmission speed of the rubbing belt 604 , the synchronous matching control adjustment component controls the tension of the rubbing belt 604 .

[0042] It should be noted that the manufactured pastry dough is conveyed by the conveyor belt connected to it. When the pastry dough is conveyed to the molding equipment body 1, it will first enter between the two kneading belts 604. Since the two kneading belts 604 are driven in reverse, the pastry dough will be directly kneaded into a specified shape after entering, which is convenient for subsequent stamping and molding. After kneading, the pastry dough will enter the stamping area of ​​the molding equipment body 1. According to the shape of the stamping mold, the molding equipment body 1 will be stamped into a specified discharge and finally collected and stored.

[0043] Reference Figure 7 As shown, the driving assembly includes an active roller 601, which is rotatably connected to the molding device body 1. A driven roller 605 is provided at the active roller 601, which is rotatably connected to the molding device body 1. The active roller 601, the auxiliary roller 603, and the driven roller 605 are all located inside the kneading belt 604 and in contact with the kneading belt 604.

[0044] Reference Figure 3 and Figure 4 As shown, the speed change drive mechanism includes a speed change assembly and a mounting box 301, the mounting box 301 is fixedly connected to the support plate 2, a first rotating shaft 312 is rotatably connected to the mounting box 301, a connecting frame 308 is fixedly mounted on the first rotating shaft 312, a driving ring 307 is fixedly mounted on the connecting frame 308, a circle of first latch teeth 311 is fixedly mounted inside the driving ring 307, and a circle of second latch teeth 313 is fixedly mounted on the outer surface of the driving ring 307.

[0045] The speed change assembly includes a motor 303, which is fixedly connected to the installation box 301. A second conical wheel 305 is fixedly installed on the power output shaft of the motor 303. A first conical wheel 304 is provided at the second conical wheel 305. The first conical wheel 304 is rotationally connected to the installation box 301. The first conical wheel 304 is fixedly connected to the first rotating shaft 312. The first conical wheel 304 and the second conical wheel 305 are connected by a first driving belt 306.

[0046] The speed change assembly also includes a first screw 302, which is rotatably connected to the installation box 301. A drive plate 309 is threadedly connected to the first screw 302, and the drive plate 309 is slidably connected to the installation box 301. A groove is provided on the drive plate 309, and the first drive belt 306 is located inside the groove.

[0047] When the forming device body 1 is working to convey the pastry dough, the motor 303 is started, and the motor 303 drives the second cone wheel 305 to rotate. The second cone wheel 305 rotates the first cone wheel 304 through the first driving belt 306. The rotation of the first cone wheel 304 will cause the first rotating shaft 312 to rotate. The rotation of the first rotating shaft 312 will cause the connecting frame 308 to rotate. The rotation of the connecting frame 308 will cause the driving ring 307 to rotate. In this way, the driving ring 307 can drive the two first gears 310 to start rotating through the first latch tooth 311 and the second latch tooth 313. The two first gears 310 rotate in opposite directions, thereby causing the two active rollers 601 to rotate in opposite directions, so that the transmission directions of the two kneading belts 604 will also be opposite. Because the transmission directions of the two kneading belts 604 are opposite, the pastry dough can be kneaded very well, and due to the power transmitted on the forming device body 1, the pastry dough can be conveyed and driven at the same time, which is convenient for kneading and stamping the pastry dough.

[0048] Reference Figure 5 As shown, the adjustment component includes a forward and reverse screw 501, which is located inside the installation box 301 and is rotatably connected to the installation box 301. A driving column 506 is threadedly connected to the forward and reverse screw 501, and the driving column 506 is slidingly connected to the installation box 301. A worm gear 502 is fixedly mounted on the forward and reverse screw 501, and a worm 503 is engaged with the worm gear 502. The worm gear 503 is rotatably connected to the installation box 301. A first bevel gear 504 is fixedly mounted on the worm 503, and a second bevel gear 505 is engaged with the first bevel gear 504. The second bevel gear 505 is fixedly connected to the first screw 302.

[0049] Since the conveying speed of the pastry dough is not constant, in order to complete the work period faster, the operating speed of the forming equipment body 1 is often increased. The uniform speed of the forming equipment body 1 is increased, which will make the conveying of the pastry dough faster and the time it stays between the two kneading belts 604 will be shorter, which will not be conducive to kneading the pastry dough. Therefore, at this time, we can rotate the first screw 302 to control the driving plate 309 to move. The movement of the driving plate 309 will cause the first driving belt 306 to move, and the movement of the first driving belt 306 will cause Its distribution position on the first cone wheel 304 and the second cone wheel 305 is changed, thereby accelerating the driving speed of the first rotating shaft 312. In this way, the first rotating shaft 312 will also make the rotation speed of the two active rollers 601 faster, and the kneading belts 604 running synchronously therewith will also be faster. In this way, the two kneading belts 604 can knead the pastry dough faster, thereby matching the conveying speed of the pastry dough of the forming equipment body 1, and can knead the pastry dough more fully, ensuring that the pastry dough will not fail in the subsequent stamping and forming process due to insufficient kneading.

[0050] When the first screw 302 is rotated to adjust the kneading speed of the kneading belt 604, the first screw 302 will also drive the worm 503 to rotate through the first bevel gear 504 and the second bevel gear 505. The rotation of the worm 503 will rotate the worm wheel 502, and the rotation of the worm wheel 502 will rotate the forward and reverse screws 501, so that the two driving columns 506 can move closer to or away from each other. In this way, the two driving columns 506 will drive the two auxiliary rollers 603 to move closer to or away from each other. When the transmission speed of the kneading belt 604 is fast, it is necessary to ensure that If the contact force between the kneading belt 604 and the active roller 601 is insufficient, the power of the active roller 601 will not be transmitted to the kneading belt 604 well, and the kneading belt 604 cannot be driven to transmit quickly. At this time, the auxiliary roller 603 will move to tighten the kneading belt 604 a little, and the same is true for slowing down the transmission speed of the kneading belt 604, which can reduce its tension and avoid excessive tension and damage to the kneading belt 604. In this way, the tension of the kneading belt 604 can be matched with the actual working speed required by the molding equipment body 1, ensuring that the kneaded dough can meet the standard.

[0051] Reference Figure 6 and Figure 8 and Figure 9 As shown, a cleaning mechanism is fixedly installed on the support plate 2, and the cleaning mechanism includes a storage box 401, which is fixedly connected to the support plate 2, and a second screw 405 is rotatably connected to the storage box 401, and a single-row pulley 404 is fixedly connected to the second screw 405. A double-row pulley 403 is fixedly installed on the first rotating shaft 312, and the double-row pulley 403 and the single-row pulley 404 are connected by a second driving belt 402.

[0052] The cleaning mechanism also includes a connecting tube 407, which is slidingly connected to the storage box 401, and a connecting box 408 is fixedly connected to the connecting tube 407. A second spring 410 is sleeved on the connecting tube 407, and the second spring 410 is fixedly connected to the storage box 401. A scraper 409 is fixedly installed on the connecting box 408, and the scraper 409 is in contact with the rubbing belt 604.

[0053] The cleaning mechanism also includes a tilting block 411, which is located inside the storage box 401 and is slidingly connected to the storage box 401. The tilting block 411 is connected to the storage box 401 through a first spring 406. The storage box 401 is slidingly connected to an extrusion column 412. The extrusion column 412 is threadedly connected to the second screw 405. A plurality of atomizing nozzles 413 are fixedly installed on the connecting box 408.

[0054] When the first rotating shaft 312 starts to rotate, the kneading belt 604 also starts to run. During the working process, when the kneading belt 604 kneads the pastry dough, the impurities attached to the kneading belt 604 will be integrated into the pastry dough, which will not only make the pastry dough unhygienic, but the scraper 409 can be directly squeezed onto the kneading belt 604 under the action of the connecting tube 407 to clean the residual pastry dough on the kneading belt 604, thereby ensuring the hygienic and safe quality of the pastry dough. In the process of rotation of the first rotating shaft 312, the second screw 405 will be rotated through the double-row pulley 403, the second drive belt 402, and the single-row pulley 404. The rotation of the second screw 405 will cause the extrusion column 412 to move up and down The squeezing column 412 moves up and down to squeeze the inclined block 411, so that the inclined block 411 squeezes the cooking oil inside the storage box 401, and the cooking oil enters the connecting box 408 through the connecting tube 407 and is sprayed out, which can act on the kneading belt 604 and lubricate the kneading belt 604. The two connecting boxes 408 are set in different orientations. The kneading belt 604 is sprayed only after the scraper 409 has cleaned the kneading belt 604. This ensures that a layer of cooking oil is always attached to the kneading belt 604, which not only reduces friction and protects the kneading belt 604, but also replenishes oil during the kneading process, reduces the adhesion between the pastry dough and the kneading belt 604, and fully ensures that the pastry dough can be used normally after kneading.

[0055] A process for preparing shortcrust pastry using a forming device comprises the following steps:

[0056] S1, equipment preparation and material delivery: the mixed cake dough is conveyed to the entrance of the forming equipment body 1 through a conveyor belt, and is ready for subsequent processing steps;

[0057] S2, kneading and shaping: Start the motor 303 to drive the speed change assembly, so that the active roller 601 and the driven roller 605 drive the kneading belt 604 to perform reverse transmission. After the pastry dough enters between the two kneading belts 604, it is subjected to the reverse force of the kneading belts 604 and is kneaded evenly into a specified shape. During the kneading process, the adjustment assembly automatically adjusts the tension of the kneading belt 604 according to the kneading speed to ensure the consistency of the kneading effect;

[0058] S3, stamping and forming: The kneaded pastry dough enters the stamping area under the conveying action of the forming device body 1, and the stamping device stamps and forms the kneaded pastry dough according to the pre-set mold shape to form a puff pastry blank with a specified shape;

[0059] S4, collection and storage: The puff pastry blanks after punching are conveyed to a collection area via a conveyor belt and stored.

[0060] Working principle: The pastry dough is transported to the forming equipment body 1 through the conveyor belt, and first enters the kneading area composed of two fences 602 and two kneading belts 604; the two kneading belts 604 are driven in reverse under the action of the driving component to knead the pastry dough, so that it enters the stamping area to complete stamping after being formed, and is finally collected and stored.

[0061] After the motor 303 is started, it drives the second cone wheel 305 to rotate, and drives the first cone wheel 304 to rotate through the first driving belt 306, thereby rotating the first rotating shaft 312.

[0062] The first rotating shaft 312 drives the connecting frame 308 and the driving ring 307 to rotate. The first latching teeth 311 and the second latching teeth 313 of the driving ring 307 respectively engage with the first gear 310, causing the two active rollers 601 to rotate in opposite directions, driving the rubbing belt 604 to transmit in opposite directions.

[0063] By rotating the first screw 302, the driving plate 309 moves in the groove, changing the distribution position of the first driving belt 306 on the first cone wheel 304 and the second cone wheel 305, and adjusting the rotation speed of the first rotating shaft 312 to match the conveying speed of the cake dough.

[0064] When the first screw 302 rotates, the worm 503 is driven to rotate via the second bevel gear 505 and the first bevel gear 504 . The worm 503 engages with the worm wheel 502 to rotate the forward and reverse screws 501 , driving the two driving posts 506 to move closer or farther away synchronously.

[0065] The driving column 506 drives the auxiliary roller 603 to move. When the rotation speed of the rubbing belt 604 increases, the auxiliary roller 603 tightens the rubbing belt 604 to enhance power transmission; when the rotation speed decreases, the tension is reduced to prevent the rubbing belt 604 from being damaged.

[0066] When the first rotating shaft 312 rotates, the second screw 405 is driven to rotate through the double-row pulley 403 , the second driving belt 402 and the single-row pulley 404 , and the squeezing column 412 moves up and down along the second screw 405 , periodically squeezing the tilting block 411 .

[0067] The tilting block 411 squeezes the cooking oil in the storage box 401, causing it to spray out from the atomizing nozzle 413 through the connecting tube 407 to lubricate the kneading belt 604; at the same time, the scraper 409 on the connecting box 408 is close to the kneading belt 604, removing residual cake dough, reducing adhesion and protecting the kneading belt 604.

[0068] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
