Description

Technical Field

[0001] The present invention relates to the field of pastry proofing, and in particular to a drawer-type fully automatic pastry proofing production line and a production process thereof. Background Art

[0002] Dough proofing equipment is a crucial piece of equipment in the field of pastry processing technology, widely used in the production of various pastries, including but not limited to baozi, steamed buns, bread, and cakes. Its primary function is to provide a constant temperature and humidity environment, ensuring a stable and efficient dough fermentation process, thereby improving pastry quality and production efficiency. Whether in large-scale quick-freezing or baking operations, food processing companies, fast food restaurants, hotels, or bakeries, dough proofing equipment plays a vital role and has become an indispensable component of the pastry and baking industry.

[0003] There are two main types of pastry proofing equipment available. One is the proofing box, which is mostly used in low-volume settings like restaurants, cafeterias, fast food restaurants, and bakeries. It typically uses electric heating tubes to directly heat the water in a sink to achieve a relatively stable temperature and humidity environment, improving the quality and efficiency of the proofing process. The other is the proofing room, a larger device often used in large pastry or baked food factories. It typically uses a steam generator or other external steam source, connected via pipes to a steam heat exchanger in the proofing room, to create a relatively suitable temperature and humidity environment to aid in the fermentation of the pasta. The main structure of this system is often constructed from polyurethane cold storage panels with an all-stainless steel exterior, creating a cabinet that is both aesthetically pleasing and durable. The proofing room is equipped with temperature and humidity control, using a unique convection method to evenly distribute air of the appropriate temperature and humidity throughout the proofing room to ensure the proper proofing of the dough. An automatic control system is also included to prevent temperature and humidity from exceeding limits, ensuring stable proofing.

[0004] However, although the existing pastry proofing equipment has met the needs of pasta processing to a certain extent, it still has some obvious defects. First of all, the existing proofing box is small in size and low in output, and is only suitable for small stores or canteens. It is not suitable for industrial production, which affects production efficiency. In the production process of existing large-scale proofing rooms, materials usually need to be loaded and unloaded manually, and each feeding requires manual input of timing and other related processes. The manual participation is high, the labor consumption is large, and the degree of intelligence is low. It cannot be integrated into a fully automatic production line. It is easy to cause low product consistency due to worker operation problems, affecting product quality. It is not easy to use in a fully automated industrial production line, and is far behind the modern industrial production's demand for high automation, high intelligence and digitalization of equipment. Summary of the Invention

[0005] The purpose of the present invention is to solve the defects of the above-mentioned proofing rooms, provide a drawer-type fully automatic pastry proofing production line and its production process, and solve the technical problems of large-scale pastry or baked food production companies in the above-mentioned background technology that the existing proofing rooms are not suitable for industrialized fully automatic production, have high labor consumption, and are not highly intelligent and digitalized, which affect the automated production efficiency and product consistency of the proofing rooms and their supporting production lines.

After the air temperature in the containment chamber 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 in the containment chamber.

[0024] A drawer-type fully automatic pastry proofing production process, the proofing production process comprising the following steps:

[0025] Step 1: using the drawer-type fully automatic pastry proofing production line according to any one of claims 1 to 9 to perform pastry proofing;

[0032] Specifically, the bracket and 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 being pulled along the sliding channel in a drawer-like manner. The first sealing baffle and the second sealing baffle, as well as the first sealing member and the second sealing member can further improve the sealing and isolation effect of the slide entrance when the bracket is opened or closed, and reduce the external gas from passing through the slide entrance into the accommodating cavity to affect the proofing environment of the pastry.

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

[0057] Reference Figure 6 The inner wall of the accommodating chamber 3 is connected with a porous plate 32, and a heating chamber 33 is formed in the accommodating chamber 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 connected to the accommodating chamber 3, and the axial flow fan 35 is installed and connected with the through hole.

[0058] Specifically, the steam heat exchanger 34 is connected to a steam inlet, a steam outlet and finned heat exchange tubes. As the steam flows, the finned heat exchange tubes dissipate the heat of the steam into the air in the area, thereby heating the air in the area.

[0059] Steam can be directly discharged into the accommodating chamber 3 through the steam exhaust pipe 37 connected on both sides to increase the air humidity in the accommodating chamber 3; the steam heat exchanger 34 is connected to the external steam generator through a circulation pipe, so that the external steam passes through the steam heat exchanger 34 to heat the air temperature in the accommodating chamber 3, and the axial flow fan 35 drives the relatively low-temperature air in the accommodating chamber 3 to the fin-type heat exchange tube and drives the relatively high-temperature air to the inside of the porous plate 32, so that the heated air passes through the porous plate 32 and is dispersed into the accommodating chamber 3. After the air temperature in the accommodating chamber 3 drops, it passes through the axial flow fan 35 again and flows to the steam heat exchanger 34 for heating. This cycle is repeated to ensure the stability of the temperature in the accommodating chamber 3.

[0060] In the dough proofing of this embodiment, the structural arrangement and drive control of the steam heat exchanger 34, the axial flow fan 35, the hot air circulation system and the humidification system belong to conventional technical means of those skilled in the art and will not be elaborated on here.

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

[0062] Specifically, in this embodiment, the manipulator 11 is an automated robotic manipulator 11 , and the driving and control of the manipulator 11 can be achieved through conventional technical means to achieve loading and unloading actions, which will not be specifically described here.

[0063] Specifically, in this embodiment, the brackets 9 are provided in several groups, and the number of the sliding channels 8 and the chute entrances 10 corresponds to the number of the brackets 9. Optionally, each bracket 9 can realize different process requirements (proofing time) of different types of products according to its number and provide alarm or instruction functions in the proofing system to ensure process stability and be compatible with the different process requirements of multiple products.

[0064] A drawer-type fully automatic pastry proofing production process, the proofing production process comprising the following steps:

[0065] Step 1: using the drawer-type fully automatic pastry proofing production line according to any one of claims 1 to 9 to perform pastry proofing;

[0066] Step 2: Adjust the temperature and humidity for proofing. Through the adjustment and control of the control cabinet 2, the hot air circulation system and the humidification system are used to provide heat and water vapor for the proofing room 1. The temperature and humidity probes and the air circulation system are used to achieve constant temperature and humidity in the proofing room 1, and to balance the temperature and humidity in each area of ​​the proofing room 1.

[0067] Step 3: feeding, the material tray loaded with pastries can be transported to the designated location through the incoming material conveyor belt 12, and the incoming material conveyor belt 12 is provided with a blocking and positioning mechanism for material separation;

[0068] In the step three, the first sealing member 20 and the second sealing member 21 for sealing the chute inlet 10 are provided in both the withdrawn and closed states of the bracket 9 to ensure that the proofing room 1 is isolated from the temperature and humidity of the outside world. Specifically, the bracket 9 and 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 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 member 20 and the second sealing member 21 can further improve the sealing and isolation effect of the chute inlet 10 when the bracket 9 is opened or closed, and reduce the external gas from passing through the chute inlet 10 into the accommodating chamber 3 to affect the proofing environment of the pastry.

[0069] Step 4: Loading, the manipulator 11 receives the control command of the control cabinet 2, uses the positioning pin 16 to draw out and open the corresponding numbered bracket 9 in a drawer-like manner, and controls the manipulator 11 through the control cabinet 2 to move the material tray on the incoming material conveyor belt 12 to the bracket 9, and slides the bracket 9 along the chute entrance 10 into the accommodating chamber 3 for proofing;

[0070] Step 5: Proofing, the control cabinet 2 records and controls the proofing time of the material tray on each bracket 9;

[0071] Step 6: Unloading. When the material of a bracket 9 is proofed, the robot 11 receives the control instruction of the control cabinet 2 to extract the corresponding bracket 9, and takes out the material tray and places 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 is embedded in the accommodating chamber 3 through the opening 4, and is detachably connected to the proofing room 1 through the connecting pieces 6 on both sides, so that the storage frame 5 can be quickly installed and disassembled, and the subsequent cleaning and maintenance of the storage frame 5 can be convenient. The installation sealing plate 7 connected by the storage frame 5 is sealed with the opening 4 end of the accommodating chamber 3, ensuring the closed nature of the proofing environment and preventing external interference. The design of the sliding channel 8 enables the bracket 9 to slide easily in the proofing room 1, which is convenient for placing and removing pastries. At the same time, the positioning pin 16 on the manipulator 11 is plugged into the plug hole 24 on the handle 23, so that it can drive the bracket 9 to slide open / close along the chute entrance 10, thereby improving the flexibility of operation and reducing the labor intensity of manual loading and unloading. The first sealing member 20 and the second sealing member 21 can ensure that the bracket 9 remains sealed with the chute entrance 10 after sliding open / close, preventing the temperature and humidity in the proofing room 1 from leaking, and reducing the entry of external gas into the accommodating chamber 3, thereby improving the stability of the proofing environment and the consistency of the product.

[0074] The hot air circulation system can maintain a stable temperature in the proofing room 1, providing a suitable proofing temperature for the pastries, and the humidification system can adjust the humidity in the proofing room 1 to ensure that the pastries will not be damaged due to improper humidity during the proofing process.
