Description

Technical Field

[0001] This utility model relates to the technical field of dough proofing boxes, specifically a continuous automatic dough proofing box. Background Technology

[0002] In the production of dried noodles and handmade noodles, the proofing of dough is a crucial step. Dough proofing, also known as malting or final fermentation, refers to the process of placing the shaped dough in a specific temperature and humidity environment for static fermentation. Therefore, as the main production equipment for dough proofing, the proofing box is indispensable. The proofing box (also known as a fermentation box) is a professional baking equipment that accelerates dough fermentation by precisely controlling the temperature and humidity environment. Its core principle is to use electric heating tubes to heat the water tank to generate steam, which, combined with a temperature control circuit, regulates the environment inside the box to form a constant temperature and humidity space, thereby simulating the optimal fermentation conditions for dough.

[0003] Existing technology, such as the patent with publication number CN221616124U, discloses a proofing box, including a proofing box body and multiple placement racks arranged sequentially from top to bottom inside the proofing box body; it also includes a spray pipe arranged above each placement rack, a spraying device connected to the air inlet end of the spray pipe, and a moving device for driving the spray pipe to move horizontally; the lower part of the spray pipe is provided with multiple spray holes; by setting the spray pipe and the spraying device connected to the spray pipe on each placement rack, when the spraying device is activated, the generated spray can enter the spray pipe and then be sprayed onto the dough on the placement rack along the multiple spray holes on the spray pipe.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] The aforementioned proofing box is equipped with a moving device that can drive the nozzle to move horizontally, allowing the nozzle to move back and forth inside the proofing box, thereby evenly spraying the spray into the dough and improving the uniformity of dough fermentation. However, during dough proofing, workers still need to stack the dough pieces one by one and then open and close the box door for proofing. In continuous production, the dough pieces can only be taken out one by one after one batch of proofing is completed before they can be put into the box for proofing again, which is inefficient. Therefore, a continuous automatic dough proofing box is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a continuous automatic dough proofing box, which consists of a proofing cavity and a proofing rack inside an outer casing. With the double-slot design of the proofing rack, the dough can be placed into the cavity for continuous proofing during the sliding process, while the proofing table on the other side can be used for the stacking and preparation of dough, maintaining the continuity of the proofing production process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous automatic proofing box for dough blanks, comprising a main frame, a steam trough at the bottom of the main frame, an outer casing, a temperature and humidity sensor fixed at the front end of the outer casing, a steam exhaust valve connected to the top of the outer casing, a proofing chamber inside the outer casing, diversion pipes arranged on both sides of the inner wall of the proofing chamber, a spray pipe connected to one side of the inner wall of the diversion pipe, a proofing rack engaged in the middle of the proofing chamber, a center sealing plate fixed at the middle end of the proofing rack, side sealing plates distributed on both sides of the center sealing plate, sealing frames embedded at the four perimeters of the center sealing plate and the side sealing plates, a handle fixed to the outer wall of the side sealing plate, proofing tables arranged inside the proofing rack, ventilation holes opened inside the proofing tables, and slide rails fixed on both sides of the bottom surface of the proofing rack.

[0008] Preferably, the temperature and humidity sensor and the exhaust valve are connected to the interior of the proofing chamber, and the proofing chamber is evenly distributed along the interior of the outer casing.

[0009] Preferably, the diverter tubes are symmetrically distributed along both sides of the waxing frame, and the nozzles are arranged at equal intervals and connected along the inner wall of the diverter tubes.

[0010] Preferably, the proofing rack is sealed and engaged with the openings at both ends of the outer casing by the sealing rubber frame around the center sealing plate and the side sealing plate, and the proofing rack forms a sliding structure with the outer casing by the slide rail.

[0011] Preferably, the proofing tables are arranged at equal intervals along both sides of the inside of the proofing rack, and the ventilation holes are opened at equal intervals along the inside of the proofing tables.

[0012] Preferably, the steam tank includes a steam chamber, with diversion pipes connected to both sides of the top surface of the steam chamber, an electric heating tube installed inside the steam chamber, a pressure relief valve connected to the front end of the steam chamber, a pressure gauge installed at the bottom of the pressure relief valve, a power supply module connected to one end of the electric heating tube, and a drain valve connected to one end of the steam chamber.

[0013] Preferably, the diversion pipe, pressure relief valve, and pressure gauge are connected to the interior of the steam chamber, and the diversion pipe is arranged at equal intervals along both sides of the top surface of the steam chamber.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses a proofing chamber inside the outer casing to proof the dough. At the same time, there are distribution pipes that are equidistant from both sides of the inner wall of the proofing chamber and communicate with the steam chamber, forming a uniform steam discharge inside the chamber, thereby maintaining the uniformity of the dough during the proofing process. In addition, the proofing rack adopts a double-slot design, which can be used in conjunction with the sliding process to place the dough in the chamber on one side of the proofing table for continuous proofing, while the dough on the other side of the proofing table can be stacked and prepared. There is no need to wait for the dough to be taken out before placing it, which streamlines the operation process, maintains the continuity of the proofing production process, and improves the overall processing efficiency.

[0016] 2. This automatic proofing box for dough can heat water to form steam through the electric heating tube inside the steam chamber, providing the temperature and humidity for the proofing space. It can be used in conjunction with the circuit control in the power supply module, using a relay self-holding circuit, i.e., the output signal of the temperature controller, to drive the intermediate relay KM to form a self-locking circuit, maintaining heating until the set upper temperature limit is reached, thereby regulating the heating temperature of the electric heating tube, thereby controlling the amount of steam generated inside, achieving the purpose of temperature and humidity control, and ensuring the stability of the proofing process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment of an automatic proofing box for continuous dough includes a main frame 1, with a steam trough 2 at the bottom of the main frame 1. The main frame 1 includes an outer casing 101, with a temperature and humidity sensor 102 fixed to the front end of the outer casing 101. A steam exhaust valve 103 is connected to the top of the outer casing 101. A proofing chamber 104 is provided inside the outer casing 101. Diverter pipes 105 are arranged on both sides of the inner wall of the proofing chamber 104, and a spray pipe 106 is connected to one inner wall of the diverter pipe 105. The middle part is fitted with a proofing rack 107, the middle end of the proofing rack 107 is fixed with a central sealing plate 108, the two sides of the central sealing plate 108 are distributed with side sealing plates 109, the four perimeters of the central sealing plate 108 and the side sealing plates 109 are embedded with sealing frames 110, the outer wall of the side sealing plates 109 is fixed with handles 111, the inside of the proofing rack 107 is arranged with proofing tables 112, the inside of the proofing tables 112 is provided with ventilation holes 113, and the bottom surface of the proofing rack 107 is fixed with slide rails 114 on both sides.

[0025] like Figure 1-4As shown, the automatic dough proofing box of this utility model is similar in structure to existing dough proofing boxes, such as the proofing box disclosed in CN221616124U. The main improvement of this utility model is that it consists of a proofing cavity 104 and a proofing rack 107 formed inside the outer casing 101. With the double-slot design of the proofing rack 107, the dough can be placed into the cavity for continuous proofing during the sliding process. Meanwhile, the proofing table 112 on the other side can be used for the stacking and preparation of dough, maintaining the continuity of the proofing production process. Continuation; In this utility model, the electric heating element 202 and the power supply module 205 are both existing technologies. When using this automatic dough proofing box, the dough pieces that need to be proofed can be placed one by one on the proofing table 112. After the dough pieces are placed on the proofing table 112, the handle 111 can be held to slide the entire proofing rack 107 along the slide rail 114 into the proofing chamber 104 of the outer box 101. Then, in conjunction with the distribution pipe 105 connected to the steam tank 2, hot steam is evenly discharged from the distributed nozzles 106 inside. A suitable temperature and humidity environment is created for proofing. The user can then continue stacking dough pieces on the exposed proofing table 112. Once the dough pieces inside have proofed, they can be directly pulled out by sliding, while the newly stacked dough pieces slide into the proofing chamber 104 for further proofing. The proofed dough pieces are collected and new dough pieces are stacked again, forming a continuous proofing process. This device uses the proofing chamber 104 inside the outer casing 101 to proof the dough pieces, while simultaneously... Both sides are equidistantly arranged with diversion pipes 105 communicating with the steam chamber 201, forming a uniform steam discharge inside the chamber, thereby maintaining the uniformity of the dough during the proofing process. The proofing rack 107 adopts a double-slot design, which can be used in conjunction with the sliding process to place the dough in the proofing table 112 on one side into the chamber for continuous proofing, while the proofing table 112 on the other side can be used for the stacking and preparation of dough. There is no need to wait for the dough to be taken out before placing it, which streamlines the operation process, maintains the continuity of the proofing production process, and improves the overall processing efficiency.

[0026] like Figure 2-4As shown, the steam tank 2 includes a steam chamber 201. Diverter pipes 105 connect to both sides of the top surface of the steam chamber 201. An electric heating element 202 is installed inside the steam chamber 201. A pressure relief valve 203 is connected to the front end of the steam chamber 201. A pressure gauge 204 is installed at the bottom of the pressure relief valve 203. One end of the electric heating element 202 is connected to a power supply module 205. One end of the steam chamber 201 is connected to a drain valve 206. Before using this proofing device, water needs to be added to the steam chamber 201 through the valve pipe at the top of the drain valve 206. Then, water can be added by opening the electric heating element 202. The water is heated to produce steam, which is discharged into the proofing chamber through the top shunt 105. The device heats the water to form steam through the electric heating tube 202 inside the steam chamber 201, providing the temperature and humidity for the proofing space. It can be coordinated with the circuit in the power supply module 205 to control the heating temperature of the electric heating tube 202 by using a relay self-holding circuit, i.e., the output signal of the temperature controller, to drive the intermediate relay KM to form a self-locking circuit, maintaining heating until the set upper temperature limit is reached. This controls the amount of steam generated inside, thereby achieving the purpose of temperature and humidity control and ensuring the stability of the proofing process.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
