Description

Technical Field

[0001] This utility model relates to the field of pastry proofing room technology, and more specifically, to a constant temperature heating device for proofing rooms. Background Technology

[0002] The proofing of pastry dough is also known as final proofing or final fermentation. After the pastry dough is shaped, it is sent to the proofing room to proof. The proofing temperature is controlled at about 35℃-40℃, the time is generally 30-60 minutes, the relative humidity is 80-90%, and the volume after proofing should increase to twice that before proofing.

[0003] Currently, most commercially available constant temperature heating devices for proofing rooms are fixedly installed inside the proofing room or proofing cavity. However, fixed heating devices can easily lead to excessively high temperatures near the heat source, while insufficient heating occurs in corners or at the bottom, resulting in uneven temperature differences and affecting the uniform proofing of the dough.

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a constant temperature heating device for a proofing room, which has the advantage of improving the proofing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature heating device for a proofing chamber, comprising a proofing chamber top wall, a positioning frame bolted to the middle part of the bottom of the proofing chamber top wall, a drive motor fixedly installed in the middle part of the positioning frame, a flange fixedly installed at the end of the output end of the drive motor, an assembly cylinder bolted to the bottom of the flange, an adjusting motor fixedly installed at the top of the assembly cylinder, the output end of the adjusting motor being a threaded shaft, an L-shaped extension arm threadedly connected to the surface of the threaded shaft, a plurality of fans fixedly installed inside the L-shaped extension arm, and through holes provided on the upper and lower sides of the working surface of the L-shaped extension arm, with heating rods fixedly installed inside the through holes.

[0006] As a preferred technical solution of this utility model, a connecting ear is fixedly installed on the top of the L-shaped extension arm, and a threaded hole is opened on one side of the connecting ear, and the threaded hole meshes with the threaded shaft.

[0008] As a preferred embodiment of this utility model, a connecting frame is bolted to the middle part of the bottom of the assembly cylinder, and a water tank is fixedly installed at the bottom of the connecting frame.

[0009] As a preferred embodiment of this utility model, a drain pipe is fixedly installed on one side of the water tank, and an atomizing nozzle is fixedly installed at the end of the drain pipe.

[0010] As a preferred technical solution of this utility model, a limiting frame is fixedly installed on one side of the bottom of the assembly cylinder and at the vertical bottom of the drive motor. A sleeve is fixedly installed in the middle part of the bottom of the limiting frame, and the sleeve is fitted onto the surface of the drain pipe.

[0011] As a preferred embodiment of this utility model, a connecting plate is fixedly installed on one side of the top of the assembly cylinder, and the connecting plate is adapted to the flange.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the structural design of a drive motor, assembly cylinder, adjustment motor, threaded shaft, and L-shaped extension arm, and through the cooperation between the structures, achieves the function of dynamic adjustment. Thus, the rotational motion can drive the fan and heating rod to rotate around the dough to be proofed, ensuring that the heat generated by the heating rod can be evenly radiated to all sides of the dough, and the hot airflow driven by the fan can also continuously wash the surface of the dough, reducing the temperature blind spots in the proofing chamber, thereby ensuring proofing efficiency and avoiding the problem of local overheating or undercooling caused by traditional fixed-position heating.

[0014] 2. The present invention, by setting the connecting ear and the threaded hole, facilitates the connection between the L-shaped extension arm and the threaded shaft, and at the same time facilitates the subsequent adjustment of the distance between the L-shaped extension arm and the assembly cylinder by rotating the threaded shaft. In addition, it can make the device suitable for different production needs, thereby ensuring the flexibility of the device. Attached Figure Description

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a constant temperature heating device for a proofing chamber, including a proofing chamber top wall 1. A positioning frame 2 is bolted to the middle part of the bottom of the proofing chamber top wall 1. A drive motor 3 is fixedly installed in the middle part of the positioning frame 2. A flange 4 is fixedly installed at the end of the output end of the drive motor 3. An assembly cylinder 5 is bolted to the bottom of the flange 4. An adjusting motor 6 is fixedly installed at the top of the assembly cylinder 5. The output end of the adjusting motor 6 is set as a threaded shaft 7. An L-shaped extension arm 8 is threadedly connected to the surface of the threaded shaft 7. Several fans 9 are fixedly installed inside the L-shaped extension arm 8. Through holes 10 are opened on the upper and lower sides of the working surface of the L-shaped extension arm 8. Heating rods 11 are fixedly installed inside the through holes 10.

[0022] The top of the L-shaped extension arm 8 is fixedly equipped with a connecting ear 12, and a threaded hole 13 is provided on one side of the connecting ear 12. The threaded hole 13 meshes with the threaded shaft 7.

[0023] The connection between the connecting lug 12 and the threaded hole 13 facilitates the increase of the connection between the L-shaped extension arm 8 and the threaded shaft 7. At the same time, it is convenient to adjust the distance between the L-shaped extension arm 8 and the assembly cylinder 5 by rotating the threaded shaft 7. In addition, the device can be adapted to different production needs, thereby ensuring the flexibility of the device.

[0024] Among them, T-shaped storage holes 14 are provided on both sides of the assembly cylinder 5 near the L-shaped extension arm 8, and T-shaped limiting rods 15 are fixedly installed on both sides of the L-shaped extension arm 8 near the assembly cylinder 5.

[0025] The T-shaped storage hole 14 provides space for the T-shaped limiting rod 15 to move, ensuring that the T-shaped limiting rod 15 and the storage tube have an overlapping function. The T-shaped limiting rod 15 can cooperate with the T-shaped storage hole 14 to limit the L-shaped extension arm 8, thereby ensuring the stability of the L-shaped extension arm 8 during movement.

[0026] The bottom of the assembly cylinder 5 is connected to a connecting frame 16 by bolts, and a water tank 17 is fixedly installed at the bottom of the connecting frame 16.

[0027] The connecting bracket 16 facilitates quick assembly and disassembly of the water tank 17 by the user, and the water tank 17 facilitates temporary storage of water to ensure a water supply for the humidification function.

[0028] A drain pipe 18 is fixedly installed on one side of the water tank 17, and an atomizing nozzle 19 is fixedly installed at the end of the drain pipe 18.

[0029] The drainage pipe 18 and the atomizing nozzle 19 work together to concentrate the water inside the water tank 17 into the aging chamber, thereby ensuring that the humidity in the aging chamber is suitable for the aging environment.

[0030] Among them, a limit frame 20 is fixedly installed on one side of the bottom of the assembly cylinder 5 and at the vertical bottom of the drive motor 3. A sleeve 21 is fixedly installed in the middle part of the bottom of the limit frame 20, and the sleeve 21 is fitted onto the surface of the drain pipe 18.

[0031] The limiting bracket 20 and the sleeve 21 work together to fix and support the drain pipe 18, thereby ensuring the stability of the atomizing nozzle 19 during operation.

[0032] A connecting plate 22 is fixedly installed on one side of the top of the assembly cylinder 5, and the connecting plate 22 is adapted to the flange 4.

[0033] The connecting plate 22 facilitates the use of flange 4 to provide space for bolt insertion, ensuring that the output of the subsequent drive motor 3 drives the assembly cylinder 5 to rotate.

[0034] The working principle and usage process of this utility model are as follows: When using this device, the motor 6 is adjusted to drive the threaded shaft 7 to rotate. The threaded shaft 7, in conjunction with the connecting ear 12, drives the L-shaped extension arm 8 to move. During this process, the T-shaped limiting rod 15, in conjunction with the T-shaped storage hole 14, constrains the L-shaped extension arm 8. The dough to be proofed is placed inside the proofing chamber and positioned at the bottom of the drive motor 3. The output end of the drive motor 3, in conjunction with the flange 4, drives the assembly cylinder 5 to rotate. The assembly cylinder 5, in conjunction with the T-shaped limiting rod 15 and the threaded shaft 7, drives the L-shaped extension arm 8 to rotate. The L-shaped extension arm 8 drives the fan 9 and heating rod 11 to rotate around the dough. The operation of the fan 9 accelerates the airflow in the proofing chamber, while the heating rod 11 heats the air. The hot air is evenly distributed in the proofing chamber under the action of the fan 9, raising and maintaining the indoor temperature. When it is necessary to increase humidity, the water in the water tank 17 is transported to the atomizing nozzle 19 through the drain pipe 18. The atomizing nozzle 19 atomizes the water and sprays it out. The mist water vapor is evenly distributed in the proofing chamber under the airflow generated by the fan 9, thus regulating the humidity.
