Description

Technical Field

[0001] This utility model relates to the field of baking equipment technology, and in particular to a dehumidification device for a baking room. Background Technology

[0002] Dehumidification of the drying oven is a crucial step in the drying process. It aims to promptly remove the humid air generated by the evaporation of moisture from the heated materials, maintaining a suitable temperature and humidity environment. This prevents moisture accumulation, which can lead to uneven drying, reduced efficiency, and decreased product quality. Dehumidification control directly affects the grade and shelf life of the final product. Effective dehumidification can not only significantly improve the drying rate and shorten the drying cycle, but also ensure the reasonable outward movement of internal moisture gradients in the materials through precise control of the humidity gradient, achieving uniform drying.

[0003] One commonly used dehumidification device is the dehumidification louver, which typically consists of multiple parallel blades installed on the side wall or top of the drying chamber. The blades can be manually adjusted or driven by an electric actuator to change the opening angle, thereby controlling the dehumidification airflow and ventilation area, and achieving phased adjustment of the dehumidification process. However, existing dehumidification louvers are mostly directly embedded in the drying chamber wall without effective air guiding and rectifying structures, making it difficult to efficiently and smoothly expel hot and humid air, thus limiting dehumidification efficiency. Especially when processing materials with high moisture content such as mushrooms, fruits, and vegetables, insufficient dehumidification capacity in the early or middle stages of high-temperature and high-humidity baking can easily cause condensation, browning, or mold growth on the material surface, seriously affecting the product's color, flavor, and appearance. Furthermore, traditional louvers have poor sealing when closed, easily leading to heat leakage, increased energy consumption, and dust accumulation on the blade surface, making cleaning and maintenance inconvenient. After long-term use, the adjustment flexibility decreases, affecting control accuracy. Therefore, there is an urgent need for a dehumidification device with efficient air guiding and good sealing performance. Utility Model Content

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1

[0029] As attached Figure 1-7 As shown, a dehumidification device for a baking oven includes a frame 1 and an electric cylinder 2; it also includes a bracket 3 fixed to the outside of the frame 1; the cylinder body 21 of the electric cylinder 2 is fixed to the bracket 3, and the push rod 22 of the electric cylinder 2 is perpendicular to the surface of the frame 1 and points to the center of the frame 1; a sealing plate 4 is fixed to the end of the push rod 22, and a stepped groove 5 is provided on the inner side of the frame 1. When the sealing plate 4 is closed, it is embedded in the stepped groove 5; a guide plate 6 extending out of the frame 1 is fixed to the outside of the sealing plate 4. The guide plate 6 is used to block the circulating airflow in the baking oven and to guide the circulating airflow out of the frame 1; a guide rod 7 is provided on the outside of the sealing plate 4, and the guide rod 7 is guided through the bracket 3.

[0030] As a preferred technical solution in this embodiment, a sealing gasket 8 is provided at the overlap between the sealing plate 4 and the stepped groove 5. The sealing gasket 8 significantly enhances the airtightness between the sealing plate 4 and the stepped groove 5 in the closed state, effectively preventing heat from leaking out of the vent, improving heat preservation performance, and reducing energy consumption. Especially in the later stage of drying and heat preservation and shaping, it helps to maintain a stable temperature field in the drying room, improve energy utilization efficiency and product quality consistency.

[0031] As a preferred technical solution in this embodiment, the outer edge of the frame 1 is provided with an outer edge portion 9. The outer edge portion 9 facilitates the overall installation and fixation of the dehumidification device to the opening of the drying room wall, improving the installation strength and sealing reliability. At the same time, it can cover the installation gaps, prevent cold air from seeping in or hot air from escaping, enhance the overall heat preservation and sealing effect, and improve the integration of the equipment and the neatness of its appearance.

[0032] As a preferred embodiment, the bracket 3 includes a U-shaped outer frame 31 and a connecting plate 32 fixed near the opening of the outer frame 31. The guide rod 7 passes through the connecting plate 32 and is guided and engaged with it. This bracket 3 structure has high rigidity and stability, effectively supporting the electric cylinder 2 and ensuring the accuracy of the movement direction of its push rod 22. The guiding engagement between the connecting plate 32 and the guide rod 7 further constrains the movement trajectory of the sealing plate 4, ensuring smooth and stable opening and closing, reducing wear, extending service life, and facilitating on-site assembly and maintenance.

[0033] As a preferred technical solution in this embodiment, the sealing plate 4 is made of insulation board. The sealing plate 4 made of insulation board has excellent heat insulation performance when closed, which significantly reduces heat conduction loss in the dehumidification port area, improves the overall heat preservation effect of the drying room, reduces energy waste, and at the same time reduces the weight of the equipment, which is conducive to reducing the drive load and achieving the dual goals of energy saving and efficient operation.

[0034] Example 2

[0035] As attached Figure 8-9 As shown, a dehumidification device for a drying oven is provided, wherein the guide plate 6 and the sealing plate 4 are set at an obtuse angle. This is essentially the same as in Embodiment 1. This angle design allows the guide plate 6 to more efficiently guide the circulating airflow within the drying oven when dehumidification is activated, causing it to smoothly turn and concentrate for discharge from the frame 1, forming an "air guide channel" effect. This improves the airflow discharge speed and dehumidification capacity, while simultaneously preventing direct airflow from causing localized disturbances, thus helping to maintain the uniformity of the drying environment.

[0036] The workflow is as follows:

[0037] The push rod 22 is driven by the electric cylinder 2. The push rod 22 is perpendicular to the surface of the frame 1 and points towards its center. The sealing plate 4, which is fixed to its end, moves in a straight line under the guidance of the guide rod 7, realizing the automatic opening and closing of the dehumidification port. When dehumidification is required, the electric cylinder 2 pushes the sealing plate 4 to open, and the guide plate 6 fixed to the outside of the sealing plate 4 moves accordingly, effectively intercepting the circulating airflow in the drying chamber, changing the direction of the circulating airflow, guiding the hot and humid air to be discharged in a specific direction, and improving the dehumidification efficiency. The guiding mechanism composed of the guide rod 7 and the bracket 3 ensures that the sealing plate 4 runs smoothly and is accurately positioned, preventing jamming or poor sealing caused by uneven load, and enhancing the system stability and automation level.

[0038] When the sealing plate 4 is closed, it is embedded in the stepped groove 5 inside the frame 1. The sealing gasket 8 at the joint between the sealing plate 4 and the stepped groove 5 enhances airtightness, effectively preventing heat from escaping through the vent, improving insulation performance and reducing energy consumption. Especially in the later stage of drying and heat preservation, it helps maintain the stability of the temperature field inside the drying room, improving energy efficiency and product quality consistency.

[0039] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
