Description

Technical Field

[0001] This invention relates to the field of dough proofing, specifically to a drawer-type fully automatic dough proofing production line and its production process. Background Technology

[0002] Dough proofing equipment is an important piece of equipment in the field of dough processing technology, widely used in the production of various dough products, including but not limited to steamed buns, bread, and pastries. Its main function is to provide a constant temperature and humidity environment to ensure a stable and efficient fermentation process for the dough, thereby improving the quality and production efficiency of the dough products. Whether in large-scale frozen food or baking enterprises, food processing companies, fast food restaurants, hotels, or bakeries, dough proofing equipment plays a crucial role and has become an indispensable piece of equipment in the dough and baking industry.

[0003] There are two main types of existing dough proofing equipment: proofing boxes and proofing rooms. Proofing boxes are commonly used in restaurants, canteens, fast food outlets, and bakeries where production volume is relatively low. They typically use electric heating elements to directly heat the water in the tank to achieve a relatively stable temperature and humidity environment, improving the quality and efficiency of proofing. Proofing rooms are larger pieces of equipment, primarily used in large-scale dough or baking factories. They usually employ steam generators or other external steam sources, connected via pipes to a steam heat exchanger within the proofing room, to create a suitable temperature and humidity environment to aid in dough fermentation. Their main structure often uses a full stainless steel shell made of polyurethane cold-storage panels, which is both aesthetically pleasing and durable. The proofing system includes temperature and humidity control, using a unique convection method to evenly distribute air of suitable temperature and humidity throughout the proofing room, ensuring optimal dough proofing. An automatic control system is also included to prevent temperature and humidity from exceeding limits, ensuring stable proofing results.

[0004] However, although existing dough proofing equipment meets the needs of pasta processing to some extent, it still has some obvious shortcomings. First, existing proofing boxes are small in size and have low output, making them suitable only for small stores or canteens, not for industrial production, thus affecting production efficiency. In addition, existing large proofing rooms usually require manual loading and unloading of materials during the production process. Each feeding requires manual input of timing and other related processes, resulting in high human involvement, high labor consumption, and low level of intelligence. They cannot be integrated into fully automated production lines, and are prone to low product consistency due to worker operation problems, affecting product quality. They are not easy to use in fully automated industrial production lines and lag far behind the requirements of modern industrial production for high automation, high intelligence, and digitalization of equipment. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned proofing rooms and provide a drawer-type fully automatic pastry proofing production line and its production process. This invention addresses the technical problems of existing proofing rooms being unsuitable for industrial-scale fully automated production, having high labor consumption, and low levels of intelligence and digitalization, which affect the automated production efficiency and product consistency of proofing rooms and their supporting production lines for large-scale pastry or baked goods manufacturers.

[0006] The objective of this invention is achieved through the following means:

[0007] This drawer-type fully automatic pastry proofing production line includes a proofing room and a control cabinet. The proofing room contains a cavity equipped with a hot air circulation system for temperature control and a humidification system for humidity control. One side of the proofing room has an opening communicating with the cavity. A storage frame is detachably connected to the proofing room through the opening. One end of the storage frame passes through the opening and is fitted into the cavity, and is detachably connected to the proofing room via a connector. The other end of the storage frame is connected to a mounting plate for matching the opening and sealing the cavity. A pull-out bracket is connected to the storage frame via a sliding channel. The mounting plate has a groove inlet that matches the sliding channel. One end of the bracket... The slide can slide open or close along the sliding channel through the chute inlet. The bracket is connected to a sealing element that has a matching opening / closing action and seals the chute inlet. Outside the proofing chamber, there is a robotic arm for feeding, an inlet conveyor belt for transferring dough, and an outlet conveyor belt. One end of the inlet and outlet conveyor belts extends toward the robotic arm. The bottom of the robotic arm is connected to a movable rail via a movable base plate. The conveying end of the movable rail extends toward the chute inlet, allowing the robotic arm to move toward the chute inlet along the movable rail. The end of the robotic arm away from the movable base plate is connected to a clamping mechanism for holding the feeding material. The clamping mechanism is connected to a positioning pin for driving the bracket to slide open / close along the chute inlet.

[0008] Furthermore, as described above, the connecting members are disposed on both sides of the storage frame, and the bottom of the storage frame is connected to several rollable support rollers. The storage frame can be conveniently rolled into the receiving cavity and embedded in the receiving cavity through the support rollers.

[0009] The storage frame is detachably connected to the proofing chamber via connectors, allowing the entire storage frame to be disassembled from the proofing chamber. It is also easily moved by the provided support rollers, which facilitates subsequent cleaning and maintenance.

[0010] At the same time, multiple storage frames are set up, and the entire storage frame can be easily disassembled and replaced, so that the entire pastry tray can be loaded and unloaded.

[0011] Further as described above, the sealing element includes a first sealing baffle and a second sealing baffle. The first sealing baffle is installed at one end of the bracket that slides into the sliding channel, and the second sealing baffle is installed at the end of the bracket near the mounting plate and exposed outside the groove inlet.

[0012] By setting a first sealing baffle and a second sealing baffle, the bracket can seal and isolate the sliding channel from the outside air when it is pulled out and opened or slid closed, thereby preventing the outside air from entering the receiving cavity through the slide inlet and reducing the impact of the outside gas on the surface fermentation environment inside the receiving cavity.

[0013] Furthermore, as described above, the first sealing baffle and the second sealing baffle are distributed opposite to each other at both ends of the bracket, and the inner surfaces of the first sealing baffle and the second sealing baffle are respectively connected to the first sealing element and the second sealing element, so that the bracket is sealed and matched with the slide inlet in the open or closed state.

[0014] The first and second seals further enhance the sealing and isolation effect of the bracket when it is pulled out and opened or slid closed, reducing the impact of external gas entering the cavity on the proofing of the pastries.

[0015] Furthermore, as described above, the inner surfaces of the first and second sealing baffles are each connected to a spring clip, and the outer surface of the second sealing baffle is connected to a handle for pulling out. The handle has a insertion hole for mating and inserting a positioning pin.

[0016] The spring clip allows the bracket to be snapped open and closed, and the insertion hole allows it to be paired with a positioning pin, enabling the bracket to slide open / close along the sliding channel via the handle.

[0017] Furthermore, as described above, the movable base plate is mounted on the movable ground rail via a sliding member, and a drive motor for driving the movable base plate to slide along the movable ground rail is connected to the movable base plate. The output shaft of the drive motor is connected to a rotating gear, and a rack is provided on the movable ground rail to mesh with the moving gear, so that the rotating gear can move along the rack under the rotation of the rotating gear.

[0018] The rotation of the drive motor allows the moving base plate to move along the extension direction of the moving track, thereby driving the robotic arm on the moving base plate to move and adjust.

[0019] Furthermore, as described above, the clamping mechanism includes a connecting plate and a plurality of grippers disposed on the connecting plate. The connecting plate is connected to the end of the robot arm via a connecting seat. The grippers include two intersecting clamping plates and a clamping rod disposed at the end of the clamping plates. The connecting plate is provided with a clamping cylinder for driving the intersecting clamping plates to perform opening and closing clamping actions.

[0020] One end of the connecting plate is connected to the positioning pin via a connecting rod. The telescopic end of the clamping cylinder is connected to the two clamping plates via a connecting rod structure. This allows the extension and retraction of the clamping cylinder to drive the two clamping plates to open and close via the connecting rod structure, thus facilitating the control of the clamping plates to drive the clamping rod for clamping and feeding.

[0021] Optionally, the number of grippers can be adjusted according to the needs of clamping and feeding, improving the applicability and flexibility of clamping and feeding.

[0022] Furthermore, as described above, the inner wall of the receiving cavity is connected to a perforated plate, and a heating chamber is formed inside the receiving cavity. The heating chamber is equipped with a steam exhaust pipe for humidification, a steam heat exchanger for heating air, and an axial flow fan. A through hole communicating with the receiving cavity is provided on the side of the heating chamber. The axial flow fan is connected to the through hole. The end of the through hole near the receiving cavity is the air inlet, and the end of the through hole near the steam heat exchanger is the air outlet. A temperature and humidity sensor for monitoring temperature and humidity is connected to the air inlet of the axial flow fan inside the receiving cavity.

[0023] Steam can be directly discharged into the air through the steam exhaust pipe to increase the humidity of the air inside the containment cavity; the steam heat exchanger is used to heat the air temperature inside the containment cavity. The axial flow fan drives the relatively low temperature air in the containment cavity to the heating chamber and drives the relatively high temperature air to the inside of the perforated plate, so that the heated air passes through the perforated plate and is dispersed into the containment cavity. After the air temperature in the containment cavity drops, it passes through the axial flow fan again and flows to the steam heat exchanger for heating. This cycle is repeated to ensure the stability of the temperature inside the containment cavity.

[0024] A proofing process for pastries, comprising the following steps:

[0025] Step 1: Proof the dough using a drawer-type fully automatic dough proofing production line;

[0026] Step 2: Adjust the temperature and humidity of the proofing room. Through the control cabinet, a hot air circulation system and a humidification system provide heat and water vapor to the proofing room. The temperature and humidity of the proofing room are kept constant through temperature control probes, humidity probes and air circulation system, and the temperature and humidity of each area of ​​the proofing room are balanced.

[0027] Step 3: Feeding. The material pallet loaded with pastries can be transported to the designated position by the material conveyor belt. The material conveyor belt is equipped with a blocking and positioning mechanism for material distribution.

[0028] Step 4: Loading. The robotic arm receives control instructions from the control cabinet and uses positioning pins to pull out the corresponding numbered bracket in a drawer-like manner. The control cabinet controls the robotic arm to move the material pallet on the incoming material conveyor belt onto the bracket, and slides the bracket along the chute inlet into the receiving cavity for proofing.

[0029] Step 5: Proofing. The proofing time of the material trays on each rack is recorded and controlled by the control cabinet.

[0030] Step Six: Unloading. Once the material in a tray has been proofed, the robot receives a control command from the control cabinet to remove the corresponding tray and place the material tray onto the discharge conveyor belt for unloading.

[0031] Furthermore, in step three, both the extended and closed states of the bracket are equipped with a first seal and a second seal to seal the inlet of the slide, so as to ensure that the proofing room is isolated from the outside temperature and humidity.

[0032] Specifically, the bracket, the first sealing baffle, and the second sealing baffle are arranged in a drawer mechanism, so that the bracket can be opened or closed by pulling it out along the sliding channel in a drawer-like manner. The first sealing baffle and the second sealing baffle, as well as the first sealing element and the second sealing element, can further improve the sealing and isolation effect on the slide entrance when the bracket is opened or closed, and reduce the external gas from passing through the slide entrance into the receiving cavity and affecting the proofing environment of the pastry.

[0033] The beneficial effects of this invention are:

[0034] One end of the storage frame passes through the opening and is embedded in the receiving cavity. It is detachably connected to the proofing room via a connector, which allows for quick and easy installation and removal of the storage frame. It also facilitates subsequent cleaning and maintenance of the storage frame. The installation sealing plate connected to the storage frame seals the opening end of the receiving cavity, ensuring the airtightness of the proofing environment and preventing external interference. The sliding channel design allows the bracket to slide easily in the proofing room, facilitating the placement and removal of pastries. At the same time, the positioning pin on the robotic arm can drive the bracket to slide open / close along the chute inlet, improving operational flexibility, reducing the labor intensity of manual loading and unloading, and ensuring that the bracket remains sealed with the chute inlet after sliding open / close, preventing the leakage of temperature and humidity in the proofing room and reducing the entry of external gas into the receiving cavity, thereby improving the stability of the proofing environment and product consistency.

[0035] The hot air circulation system maintains a stable temperature in the proofing room, providing a suitable proofing temperature for the pastries. The humidification system regulates the humidity in the proofing room, ensuring that the pastries are not damaged due to improper humidity during the proofing process. Meanwhile, the incoming and outgoing conveyor belts continuously transport material pallets to designated positions. Combined with the gripping mechanism of the robotic arm, the loading and unloading of pastry material pallets on the incoming and outgoing conveyor belts are automated, improving production efficiency and enabling continuous operation of the production line. The gripping mechanism firmly holds the material pallets, preventing slippage or damage during the loading process, and automating the placement and removal of materials, further enhancing the automation level of the production line.

Detailed Implementation

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0049] In this embodiment, refer to Figures 1-11 The specific implementation of the drawer-type fully automatic pastry proofing production line includes a proofing room 1 and a control cabinet 2. The proofing room 1 has a receiving cavity 3, which is equipped with a hot air circulation system for constant temperature and a humidification system for constant humidity. One side of the proofing room 1 has an opening 4 communicating with the receiving cavity 3. A storage frame 5 is detachably connected to the proofing room 1 through the opening 4. One end of the storage frame 5 passes through the opening 4 and is embedded in the receiving cavity 3, and is detachably connected to the proofing room 1 via a connector 6. The other end of the storage frame 5 is connected to a mounting plate 7 for matching the opening 4 and sealing the receiving cavity 3. A pull-out sliding bracket 9 is connected to the storage frame 5 through a sliding channel 8. The mounting plate 7 has a sliding groove inlet 10 that matches the sliding channel 8, and one end of the bracket 9 passes through the sliding groove inlet. The 10 can be slidably opened or closed along the sliding channel 8, and the bracket 9 is connected to a sealing element that has a pairing opening / closing action and seals the chute inlet 10. The periphery of the proofing chamber 1 is provided with a robot arm 11 for feeding, a material conveyor belt 12 for conveying pastries, and a material discharge conveyor belt 13. One end of the material conveyor belt 12 and the material discharge conveyor belt 13 extends toward the robot arm 11. The bottom of the robot arm 11 is connected to a movable ground rail 15 through a movable base plate 14. The conveying end of the movable ground rail 15 extends toward the chute inlet 10, so that the robot arm 11 can move along the movable ground rail 15 toward the chute inlet 10. The end of the robot arm 11 away from the movable base plate 14 is connected to a clamping mechanism for clamping the feeding. The clamping mechanism is connected to a positioning pin 16 for driving the bracket 9 to slide open / close along the chute inlet 10.

[0050] Reference Figure 7 and Figure 8 The connecting parts 6 are disposed on both sides of the storage frame 5. Several rollable support rollers 17 are connected to the bottom of the storage frame 5, allowing it to easily roll into and be fitted into the receiving cavity 3 via the support rollers 17. The storage frame 5 is detachably connected to the proofing room 1 via the connecting parts 6, allowing it to be completely disassembled from the proofing room 1. The support rollers 17 also allow for easy movement of the storage frame 5, facilitating subsequent cleaning and maintenance. Furthermore, the arrangement of multiple storage frames 5 allows for easy replacement and assembly, enabling the overall loading and unloading of the pastry tray 9.

[0051] Reference Figure 10 and Figure 11 The sealing element includes a first sealing baffle 18 and a second sealing baffle 19. The first sealing baffle 18 is installed at one end of the bracket 9 that slides into the sliding channel 8, and the second sealing baffle 19 is installed at one end of the bracket 9 near the mounting sealing plate 7 and is exposed outside the slide groove inlet 10. By setting the first sealing baffle 18 and the second sealing baffle 19, the bracket 9 can seal and isolate the sliding channel 8 from the external air when it is pulled out and opened or slid closed, thereby preventing external air from passing through the slide groove inlet 10 into the receiving cavity 3 and reducing the impact of external gas on the ignition environment inside the receiving cavity 3.

[0052] Reference Figures 7-11 The first sealing baffle 18 and the second sealing baffle 19 are distributed opposite each other at both ends of the bracket 9, and the inner surfaces of the first sealing baffle 18 and the second sealing baffle 19 are respectively connected to the first sealing element 20 and the second sealing element 21, so that the bracket 9 is sealed and matched with the slide inlet 10 in the open or closed state. The first sealing element 20 and the second sealing element 21 further enhance the sealing and isolation effect of the bracket 9 when it is pulled out and opened or slid closed, reducing the impact of external gas entering the receiving cavity 3 on the evaporation of the surface. The inner surfaces of the first sealing baffle 18 and the second sealing baffle 19 are each connected to a spring buckle 22, and the outer surface of the second sealing baffle 19 is connected to a handle 23 for pulling out. The handle 23 has a plug hole 24 for mating and inserting the positioning pin 16.

[0053] Specifically, both the first sealing element 20 and the second sealing element 21 are made of silicone foam sealing gaskets. The design of the silicone foam sealing gaskets effectively improves the sealing and heat preservation performance of the fermentation environment inside the accommodating cavity 3. The spring buckle 22 allows the bracket 9 to be snapped on and off, and it can be paired with the positioning pin 16 through the insertion hole 24, so that the bracket 9 can be slid open / closed along the sliding channel 8 by the handle 23.

[0054] Reference Figures 1-4 The movable base plate 14 is mounted on the movable ground rail 15 via a sliding member 25. A drive motor 26 is connected to the movable base plate 14 to drive it to slide along the movable ground rail 15. The output shaft of the drive motor 26 is connected to a rotating gear 27. A rack 28 is provided on the movable ground rail 15 to mesh with the rotating gear, allowing the rotating gear 27 to move along the rack 28. The rotation of the drive motor 26 allows the movable base plate 14 to move along the extension direction of the movable ground rail 15, thereby enabling the robotic arm 11 on the movable base plate 14 to move and adjust.

[0055] Reference Figure 4 and Figure 5 The clamping mechanism includes a connecting plate 29 and three grippers 30 disposed on the connecting plate 29. The connecting plate 29 is connected to the end of the robot arm 11 via a connecting seat 31. Each gripper 30 includes two intersecting clamping plates 301 and a clamping rod 302 disposed at the end of each clamping plate 301. The connecting plate 29 is provided with a clamping cylinder 303 for driving the intersecting clamping plates 301 to perform opening and closing clamping actions. One end of the connecting plate 29 is connected to a positioning pin 16 via a connecting rod. The telescopic end of the clamping cylinder 303 is connected to the two clamping plates 301 via a connecting rod structure, so that the telescopic movement of the clamping cylinder 303 can drive the two clamping plates 301 to perform opening and closing actions via the connecting rod structure, thereby facilitating the control of the clamping plates 301 to drive the clamping rod 302 to clamp and feed materials.

[0056] Optionally, the number of grippers 30 can be adjusted according to the needs of clamping and feeding, thereby improving the applicability and flexibility of clamping and feeding.

[0057] Reference Figure 6 The inner wall of the receiving cavity 3 is connected to a perforated plate 32, and a heating chamber 33 is formed inside the receiving cavity 3. The heating chamber 33 is provided with a steam exhaust pipe 37 for humidification, a steam heat exchanger 34 for heating air, and an axial flow fan 35. The side of the heating chamber 33 is provided with a through hole communicating with the receiving cavity 3. The axial flow fan 35 is connected to the through hole. The end of the through hole near the receiving cavity 3 is the air inlet end, and the end of the through hole near the steam heat exchanger 34 is the air outlet end. A temperature and humidity sensor 36 for monitoring temperature and humidity is connected to the air inlet end of the receiving cavity 3 near the air inlet end of the axial flow fan 35.

[0058] Specifically, the steam heat exchanger 34 is connected to a steam inlet, a steam outlet, and finned heat exchange tubes. Through the steam flow, the finned heat exchange tubes dissipate the heat of the steam into the air in the area to heat the air in that area.

[0059] Steam can be directly discharged into the containment cavity 3 through the steam exhaust pipes 37 on both sides to increase the air humidity inside the containment cavity 3; the steam heat exchanger 34 is connected to the external steam generator through the circulation pipe, so that the external steam passes through the steam heat exchanger 34 to heat the air temperature inside the containment cavity 3; the axial flow fan 35 drives the relatively low temperature air in the containment cavity 3 to the finned heat exchange tube and drives the relatively high temperature air to the inside of the perforated plate 32, so that the heated air passes through the perforated plate 32 and is dispersed into the containment cavity 3; after the air temperature in the containment cavity 3 drops, it passes through the axial flow fan 35 again and flows to the steam heat exchanger 34 for heating, and so on to ensure the stability of the temperature inside the containment cavity 3.

[0060] In this embodiment, the structure and drive control of the steam heat exchanger 34, axial flow fan 35, hot air circulation system and humidification system during the proofing process are conventional technical means for those skilled in the art, and will not be described in detail here.

[0061] Specifically, the incoming conveyor belt 12 and the outgoing conveyor belt 13 are respectively connected to the incoming drive motor and the outgoing drive motor, so that they can drive the material pallets on the conveyor belt to be transported along the conveying direction. The specific transmission structure and operating principle of the incoming conveyor belt and the outgoing conveyor belt in this embodiment are conventional technical means and will not be described in detail here.

[0062] In this embodiment, the robotic arm 11 is an automated robot robotic arm 11. The driving and control of the robotic arm 11 can be achieved through conventional technical means to realize the loading and unloading actions, which will not be described in detail here.

[0063] Specifically, in this embodiment, several sets of brackets 9 are provided, and the number of sliding channels 8 and chute inlets 10 corresponds to the number of brackets 9. Optionally, each bracket 9 can realize different process requirements (proofing time) for different types of products according to its number, and perform alarm or command functions in the proofing system to ensure process stability and compatibility with the needs of different processes for multiple products.

[0064] A proofing process for pastries, comprising the following steps:

[0065] Step 1: Proof the dough using a drawer-type fully automatic dough proofing production line;

[0066] Step 2: Adjust the temperature and humidity of the proofing room. Through the adjustment and control of the control cabinet 2, the hot air circulation system and humidification system provide heat and water vapor to the proofing room 1. The temperature and humidity of the proofing room 1 are kept constant through the temperature control probe, humidity probe and air circulation system, and the temperature and humidity of each area of ​​the proofing room 1 are balanced.

[0067] Step 3: Feeding. The material pallet loaded with pasta can be transported to the designated position by the material conveyor belt 12. The material conveyor belt 12 is equipped with a blocking and positioning mechanism for distributing materials.

[0068] In step three, the bracket 9 is equipped with a first sealing element 20 and a second sealing element 21 for sealing the slide inlet 10 in both the extended and closed states, to ensure that the proofing room 1 is isolated from the outside temperature and humidity. Specifically, the bracket 9, the first sealing baffle 18, and the second sealing baffle 19 are arranged in a drawer mechanism, so that the bracket 9 can be opened or closed by pulling it out along the sliding channel 8 in a drawer-like manner. The first sealing baffle 18 and the second sealing baffle 19, as well as the first sealing element 20 and the second sealing element 21, can further improve the sealing and isolation effect on the slide inlet 10 when the bracket 9 is opened or closed, and reduce the amount of external gas entering the receiving cavity 3 through the slide inlet 10 and affecting the proofing environment of the pastries.

[0069] Step 4: Loading. The robot arm 11 receives control instructions from the control cabinet 2 and uses the positioning pin 16 to pull out the corresponding numbered bracket 9 in a drawer-like manner. The robot arm 11 is controlled by the control cabinet 2 to move the material pallet on the material conveyor belt 12 to the bracket 9 and slide the bracket 9 along the chute inlet 10 into the receiving cavity 3 for proofing.

[0070] Step 5: Proofing. The proofing time of the material trays on each rack 9 is recorded and controlled by the control cabinet 2.

[0071] Step 6: Unloading. After the material in a tray 9 has been fermented, the robot arm 11 receives the control command from the control cabinet 2 to pull out the corresponding tray 9 and remove the material tray and place it on the discharge conveyor belt 13 for unloading.

[0072] The difference between this embodiment and the prior art is that:

[0073] One end of the storage frame 5 passes through the opening 4 and is embedded in the receiving cavity 3. It is detachably connected to the proofing room 1 through the connectors 6 on both sides, so that the storage frame 5 can be quickly installed and disassembled. At the same time, it is convenient to clean and maintain the storage frame 5. The installation sealing plate 7 connected to the storage frame 5 seals the opening 4 of the receiving cavity 3, ensuring the airtightness of the proofing environment and preventing external interference. The design of the sliding channel 8 allows the bracket 9 to slide easily in the proofing room 1, which is convenient for the placement and removal of pastries. At the same time, the positioning pin 16 on the robotic arm 11 is inserted into the insertion hole 24 on the handle 23, which can drive the bracket 9 to slide open / close along the slide inlet 10, improving the flexibility of operation and reducing the labor intensity of manual loading and unloading. The first sealing element 20 and the second sealing element 21 ensure that the bracket 9 remains sealed with the slide inlet 10 after sliding open / close, preventing the temperature and humidity in the proofing room 1 from leaking out and reducing the entry of external gas into the receiving cavity 3, thereby improving the stability of the proofing environment and the consistency of the product.

[0074] The hot air circulation system maintains a stable temperature inside the proofing room 1, providing a suitable proofing temperature for the pastries. The humidification system regulates the humidity inside the proofing room 1, ensuring that the pastries are not damaged due to improper humidity during the proofing process. Meanwhile, the incoming conveyor belt 12 and the outgoing conveyor belt 13 continuously transport the material trays loaded with pastries to the designated positions. Combined with the gripping mechanism of the robotic arm 11, the material trays on the incoming conveyor belt 12 and the outgoing conveyor belt 13 are automatically loaded and unloaded, improving production efficiency and enabling continuous operation of the production line. The gripper 30 can firmly hold the material trays to prevent slippage or damage during the loading process, realizing automated placement and removal of materials and further improving the automation level of the production line.

[0075] In summary, the drawer-type fully automatic pastry proofing production line of the present invention can achieve fully automatic production, save labor, ensure process stability, and be compatible with the process requirements of different proofing times for various products.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
