Description

Technical Field

[0001] This invention relates to the field of pastry production technology, specifically to an automated pastry production equipment. Background Technology

[0002] Pastries are foods made from powdered grains (mainly wheat flour, rice flour, etc.), but also include foods made primarily from grains, fruits, fish, shrimp, and root vegetables, using techniques such as wrapping and shaping, and incorporating fillings and seasonings, and then cooked. In the south, they are commonly called "dim sum," while in the north they are called "noodles."

[0003] However, existing technologies still have the following problems: First, existing automated pastry production equipment relies heavily on manual sorting and transfer of materials, which is not only time-consuming but also prone to efficiency issues due to human error. Furthermore, the precision of the processing components is insufficient, often resulting in material waste and low effective processing volume per unit time.

[0004] Secondly, existing automated pastry production equipment lacks an effective vibration screening structure, resulting in inconsistent specifications of pastry raw materials entering the processing stage, leading to poor consistency in subsequent processing. At the same time, if the cleaning components are not cleaned in a timely manner, residual impurities can easily cause cross-contamination, affecting the cleanliness of the pastry surface.

[0005] Furthermore, in existing automated pastry production equipment, the sieves and related components are mostly fixedly connected, making it difficult to replace them according to different pastry raw material specifications, and the angle of the guiding structure cannot be adjusted; the cleaning components are inconvenient to disassemble and assemble, making it difficult to maintain and replace them later, and it is difficult to adapt to diverse cleaning needs.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figure 1-8 As shown, this invention provides an automatic pastry production equipment, including a body 1. The lower surface of the body 1 is symmetrically equipped with universal casters 11. These casters 11 not only facilitate the overall movement of the equipment and adapt to different production scenarios, but also ensure the stability of the body 1 during operation through their locking function, preventing displacement due to vibration from affecting processing accuracy. A processing component 2 is fixedly mounted on the upper side of the body 1. A transmission pipe 3 is fixedly mounted on one side of the processing component 2, and a nozzle assembly 31 is fixedly mounted at the lower end of the transmission pipe 3. A transmission belt 4 is mounted on the upper surface of the body 1, and a screening frame 5 is fixedly mounted on the upper surface of the screening frame 5. Several sieve holes 51 are opened on the upper surface of the screening frame 5. A support 7 is mounted on one side of the body 1, and a cleaning scraper 72 is mounted on the inner side of the support 7. The transmission belt 4 is responsible for conveying the materials to be processed. The support column 42 is in contact with the tensioned portion 41 of the transmission belt 4 to ensure stability during transmission.

[0028] A support block 6 is fixedly mounted on the upper surface of the machine body 1, and a motor 61 is fixedly mounted on one side of the support block 6. The output end of the motor 61 passes through the support block 6 and is fixedly mounted with a cam 62. A connecting rod 63 is rotatably mounted on one side of the outer surface of the cam 62. Lifting plates 64 are symmetrically mounted on the upper side of the machine body 1. The end of the connecting rod 63 is rotatably connected to one of the lifting plates 64. The inner side of the lifting plate 64 is detachably connected to the screening frame 5. Vertical positioning frames 65 are symmetrically fixed on the upper surface of the machine body 1, and the outer side of the lifting plate 64 is engaged with the corresponding vertical positioning frame 65. Within the vertical positioning frame 65, mounting strips 67 are symmetrically fixed on both sides of the screening frame 5, and the mounting strips 67 are bolted to the corresponding lifting plates 64. Inclined guide plates 68 are symmetrically bolted to the lower sides of the screening frame 5, and movable bolt slots 69 are symmetrically provided on the inclined guide plates 68. Material is first conveyed to the screening frame 5. The motor 61 drives the cam 62 to rotate, which in turn drives the lifting plates 64 to reciprocate up and down within the vertical positioning frame 65 via the connecting rod 63, thus causing the screening frame 5 to vibrate synchronously. Material is screened through the screen holes 51, and material meeting the specifications falls. The inclined guide plates 68 (whose angle can be adjusted via the movable bolt slots 69) guide the screened material to the subsequent processing area. The vertical positioning frame 65 limits the movement of the lifting plates 64, ensuring that the lifting plates 64 do not deviate during reciprocating motion, thus guaranteeing the stability of the vibration of the screening frame 5 and improving the screening effect. The bolted connection between the mounting strip 67 and the lifting plate 64 makes the assembly and disassembly of the screening frame 5 more convenient, facilitating the replacement of screening frames 5 with different screen holes 51 according to the specifications of different powder materials. The design of the movable bolt groove 69 allows for more flexible adjustment of the angle of the inclined guide plate 68, which can adapt to the needs of different conveying paths and ensure that the screened materials are accurately guided to the processing area.

[0029] A rotating plate 71 is rotatably installed inside the bracket 7, and the upper surface of the rotating plate 71 is detachably connected to the cleaning scraper 72. Several spring posts 73 are fixedly connected between the rotating plate 71 and the bracket 7. An insert plate 74 is fixedly installed on the lower surface of the cleaning scraper 72 and is inserted into the upper side of the rotating plate 71. Side connecting plates 75 are symmetrically fixed on both sides of the rotating plate 71, and the side connecting plates 75 are fixedly connected to the cleaning scraper 72 by bolts. The processing component 2 transports the processing medium (such as paint, cleaning agent, etc.) to the nozzle component 31 through the transmission pipe 3 to precisely process the screened material. The rotating plate 71 inside the bracket 7 remains stable under the elastic force of the spring column 73. The cleaning scraper 72 contacts the transmission belt 4 or the machined surface, cleaning residual materials or impurities as the equipment runs. The cooperation of the insert plate 74 and the side connecting plate 75 ensures the secure installation and convenient replacement of the cleaning scraper 72. The rotating connection between the rotating plate 71 and the bracket 7, combined with the elastic force of the spring column 73, ensures that the cleaning scraper 72 always fits tightly against the transmission belt 4 or the machined surface, improving the cleaning effect. The insert plate 74 is inserted into the upper side of the rotating plate 71, and together with the bolts fixing the side connecting plate 75 to the cleaning scraper 72, it provides double protection for the secure installation of the cleaning scraper 72, while also facilitating the disassembly and replacement of the cleaning scraper 72, reducing maintenance costs.

[0030] The upper surface of the machine body 1 is symmetrically fixed with side support plates 21, and several drive shafts 22 and transmission shafts 23 are rotatably arranged between the two side support plates 21. A tensioning section 41 is provided on the transmission belt 4, and a support column 42 is rotatably arranged between the two side support plates 21. The inner surface of the tensioning section 41 is in contact with the support column 42. The transmission belt 4 is responsible for conveying the material to be processed. The support column 42 is in contact with the tensioning section 41 of the transmission belt 4 to ensure stability during transmission. The side support plates 21 provide stable support for the drive shafts 22 and transmission shafts 23. The drive shafts 22 rotate under the drive of the power unit, and drive the transmission belt 4 through cooperation with the transmission shafts 23, ensuring the continuity of material conveying. The fixed connection between the transmission pipe 3 and the processing component 2 ensures the stability of the processing medium conveying path. The position design of the nozzle assembly 31 can accurately align with the screened material, reducing ineffective spraying of the processing medium and further improving processing efficiency.

[0031] The machine body 1 is equipped with a collection hopper 12, and a vent pipe 13 is fixedly installed on one side of the collection hopper 12. The end of the vent pipe 13 passes through the machine body 1 and extends to the outside of the machine body 1. Two support rods 81 are fixedly installed inside the machine body 1, and a protective component 8 is fixedly installed on the upper surface of the two support rods 81. Waste generated during screening and processing falls into the collection hopper 12 inside the machine body 1. The vent pipe 13 can be connected to a negative pressure device to accelerate waste collection and prevent accumulation. The protective component 8 supported by the support rods 81 protects key components inside the machine body 1 (such as motors and transmission structures), reducing material splashing or the impact of the external environment. The shape design of the collection hopper 12 is conducive to the centralized collection of waste. The connection between the vent pipe 13 and the negative pressure device can quickly suck away the waste, preventing waste from accumulating in the collection hopper 12, preventing bacterial growth, and ensuring a hygienic production environment. The support rod 81 provides stable support for the protective component 8. The protective component 8 can effectively prevent material splashing from damaging the key internal components of the machine body 1, and at the same time, it can isolate the internal components from the influence of external dust and other impurities, thus extending the service life of the equipment.

[0032] The core advantage of this invention lies in the synergistic linkage of its components, forming a closed-loop production chain of "screening-processing-transfer-cleaning-collection". When the equipment starts, the motor 61 first drives the screening frame 5 to vibrate, while the transmission belt 4 operates synchronously. The two are matched in speed through the PLC control system. The ratio of screening frequency to transmission belt speed can be adjusted through the touch panel. For highly viscous dough such as glutinous rice ball dough, the screening frequency can be reduced to 30 times / minute, while the transmission belt speed can be adjusted to 0.5m / s to prevent material from sticking to the screen holes. For loose flour dough, the frequency can be increased to 60 times / minute and 1.2m / s, greatly improving processing efficiency.

[0033] The screen holes 51 of the screening frame 5 adopt a stepped aperture design, with an 8mm aperture at the inlet and a gradually decreasing aperture to 5mm at the outlet. The tilt angle, adjusted to match the vibration direction, can be controlled via bolts on the lifting plate 64, ranging from 3° to 8°, allowing for natural grading of materials during screening. Large pieces of material that do not meet specifications slide along the edge of the screening frame into the side recovery trough, preventing secondary contamination. The bolts connecting the mounting strip 67 and the lifting plate 64 use anti-loosening nuts, ensuring fixation even under high-frequency vibration. Disassembly and assembly can be completed with just a special wrench, and replacing the screening frame with different aperture specifications takes no more than 5 minutes.

[0034] The movable bolt slot 69 of the inclined guide plate 68 is 15cm long and 1.2cm wide, allowing for ±30° angle adjustment by loosening the bolts. When processing dumpling wrapper raw materials, the guide plate is adjusted to a 15° angle to allow the material to fall smoothly onto the conveyor belt; when processing steamed bun dough, it is adjusted to 25°, utilizing gravity to accelerate the material's entry into the processing area. The guide plate surface is covered with a food-grade silicone coating with a friction coefficient ≤0.15, effectively preventing dough from sticking together.

[0035] The processing component 2 is equipped with a twin-screw extrusion structure. Through the drive shaft 22 between the side support plates 21 and the transmission shaft 23, continuous kneading and shaping of the dough is achieved. The spiral ridges on the surface of the drive shaft 22 have a spacing of 2cm, allowing the rotation speed to be adjusted from 50-200rpm depending on the dough hardness. Soft dough uses a lower speed to avoid over-kneading and gluten breakage, while hard dough uses a higher speed to enhance extensibility. The inner wall of the transmission pipe 3 has a smoothness of Ra0.8μm, and the detachable nozzle assembly 31 offers a choice of diameters from 3 to 10mm, enabling precise extrusion of strips, dots, or sheets of dough with an error controlled within ±0.2mm, solving the problem of uneven extrusion in traditional equipment.

[0036] The transmission belt 4 is made of food-grade polyurethane material, 2mm thick, with a 0.5mm deep diamond-shaped texture on the surface. This ensures friction to prevent material slippage while avoiding the accumulation of residual flour. The contact pressure between the tensioned part 41 and the support column 42 is controlled within a range of 5-15N by a spring adjustment device. After the transmission belt has run for 100 hours, it can be retightened by rotating the adjusting nut at the end of the support column, extending its service life to over 5000 hours. An infrared beam sensor is installed on the inner side of the side support plate 21. When the material accumulation thickness on the transmission belt exceeds 3cm, the equipment automatically reduces the vibration frequency of the screening frame and increases the transmission speed to achieve dynamic balance.

[0037] The cleaning scraper 72 is made of food-grade PP material, with a 30° acute angle at the bottom edge. The contact pressure between the scraper and the drive belt surface is adjusted from 2 to 8 N via the spring post 73. The clearance between the insert plate 74 and the rotating plate 71 is ≤0.1 mm, ensuring that the scraper does not shift during high-speed movement. When cleaning the scraper is required, it can be pulled out by loosening the bolts on the side connecting plate 75, and reinserted after cleaning. The entire process requires no tools and meets the rapid cleaning requirements of food production. The spring post 73 has an elasticity coefficient of 1.2 N / mm, which can buffer the slight vibration of the drive belt, ensuring cleaning effectiveness while preventing scratches on the drive belt surface.

[0038] All parts of this equipment that come into direct contact with food are made of materials that comply with GB4806.9-2016 standards: the screening frame 5 is made of 304 stainless steel and is electrolytically polished with a surface roughness ≤Ra0.4μm, which is resistant to corrosion from acidic substances in dough and prevents bacterial growth; the polyurethane material of the transmission belt 4 is FDA certified and can withstand 121℃ high-temperature steam sterilization. It can be directly rinsed with 80℃ hot water for daily cleaning without deformation or the release of harmful substances.

[0039] The twin screw of processing component 2 undergoes a food-grade nitriding process, achieving a hardness of HV800 or higher. This ensures wear resistance during dough kneading while preventing metal fragments from contaminating the material. The detachable nozzle of nozzle component 31 features a built-in silicone sealing ring that meets GB4806.11-2016 requirements, providing durable sealing performance and preventing leakage of the processing medium.

[0040] In terms of energy consumption, the equipment adopts a variable frequency drive system: motor 61 is a YE3 series high-efficiency energy-saving motor with a rated power of 1.5kW, which saves 15% to 20% of electricity compared with traditional motors; the drive shaft 22 of the transmission belt 4 is equipped with a magnetic powder clutch, which can automatically adjust the output torque according to the material load, and the energy consumption is reduced to 30% of the rated value when unloaded. The overall standby power of the equipment is ≤50W, which meets the Class II energy efficiency standard of GB18613-2020 "Energy Efficiency Limits and Energy Efficiency Grades of Small and Medium-sized Three-phase Asynchronous Motors".

[0041] In terms of operational safety, the edges of the machine body 1 are all rounded with a radius of ≥5mm to prevent operators from bumping into them; a protective mesh with a hole diameter of ≤10mm is installed on the outside of the screening frame 5 to prevent material from splashing during vibration; the emergency stop button adopts a red mushroom head design and is installed on both sides of the machine body. After being pressed, it cuts off all power supply within 0.5 seconds to ensure safety in emergency situations.

[0042] These design details not only meet the hygiene and safety requirements of food production, but also reduce operating costs through energy-saving technologies, further enhancing the practical value of the equipment.

[0043] The collection hopper 12 inside the main body 1 adopts a funnel-shaped design with a 60° tilt at the bottom to ensure that waste materials slide off naturally. The ventilation pipe 13 can be connected to a negative pressure fan with an airflow of 150m³ / h. 3 The system operates at / h, activated during the processing of starch-based pastries. It uses negative pressure to draw drifting dust into a collection bag, ensuring an environmental dust concentration ≤5mg / m³. 3 It complies with the GBZ2.1-2019 hygiene standard. The protective component 8 is made of transparent acrylic sheet with a thickness of 5mm. It can both observe the internal operating status and prevent material splashing. Its connection with the support rod 81 adopts quick-release buckle, which facilitates the maintenance of internal components.

[0044] The equipment is equipped with a 7-inch touchscreen and has 10 built-in preset programs for making steamed buns, dumplings, noodles, etc. Operators can recall parameters with one click or store 20 custom recipes. The system has a self-diagnostic function; when the motor is overloaded, the drive belt is misaligned, or the screen holes are blocked, it will immediately stop and display fault codes such as E01 (motor overheating) and E02 (loose scraper), while simultaneously sounding an alarm. The swivel casters 11 are equipped with brakes, and the friction between the wheel rim and the ground is ≥300N when braking, ensuring stable operation of the equipment under vibration conditions.

[0045] The equipment can be flexibly adjusted to suit the characteristics of different regions' pastries: when making southern glutinous rice pastries, an atomizing humidifier can be added and connected via a pre-reserved interface in the transmission pipeline to maintain the dough humidity at 45%–50%; when making northern hard noodles, the low-temperature cooling system of the processing components, with its built-in semiconductor refrigeration chip, can be activated to control the dough temperature at 18–22℃ to prevent the gluten from softening. Working principle: The transmission belt 4 is responsible for conveying the material to be processed. The support column 42 is in contact with the tensioned part 41 of the transmission belt 4 to ensure stability during the transmission process. The material is first conveyed to the screening frame 5. The motor 61 drives the cam 62 to rotate, which drives the lifting plate 64 to move up and down in the vertical positioning frame 65 through the connecting rod 63, thereby causing the screening frame 5 to vibrate synchronously. The material is screened through the screen holes 51. The material that meets the specifications falls down, and the inclined guide plate 68 (the angle of which can be adjusted by the movable bolt slot 69) guides the screened material to the subsequent processing area. Processing component 2 delivers processing media (such as paint, cleaning agent, etc.) to nozzle component 31 via transmission pipe 3 for precise processing of the screened material. The rotating plate 71 inside the bracket 7 remains stable under the elastic force of spring column 73. The cleaning scraper 72 contacts the transmission belt 4 or the processing surface, cleaning residual materials or impurities as the equipment runs. The cooperation of the insert plate 74 and the side connecting plate 75 ensures the secure installation and convenient replacement of the cleaning scraper 72. Waste generated during screening and processing falls into the collection hopper 12 inside the machine body 1. The vent pipe 13 can be connected to a negative pressure device to accelerate waste collection and prevent accumulation. The protective component 8 supported by the support rod 81 protects key internal components (such as motors and transmission structures) of the machine body 1, reducing material splashing or the impact of the external environment. This equipment is compatible with powdered raw materials such as flour and rice flour, and can also process fillings such as fruits, fish and shrimp. It also caters to the needs of techniques such as wrapping and pinching, meeting the diverse production needs of pasta and noodles from both the north and south, and helping to improve the standardization and efficiency of production.

[0046] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
