Description

Technical Field

[0001] This utility model relates to the field of dried bean curd processing technology, specifically to a dried bean curd drying equipment with hot air circulation. Background Technology

[0002] Tofu skin drying equipment is a specialized machine that uses heat pumps, steam, or air energy technology to precisely control temperature and humidity, quickly removing moisture from tofu skin. This extends the shelf life of tofu skin, reducing the moisture content from 30% to 10-13%, while retaining nutrients, improving taste and color, and preventing quality degradation caused by high-temperature oxidation. It is mainly used in the food processing industry and is suitable for small and medium-sized tofu skin workshops as well as large-scale production lines. However, current tofu skin drying equipment still has the following shortcomings:

[0003] For example, patent document CN212658019U discloses a drying device for dried bean curd production. This drying device divides a rectangular cylinder into multiple cavities using partitions. A mesh belt rotates via a belt shaft and runs within the cavities, with dried bean curd placed on the belt. While this design is reasonable—the partitions divide the rectangular cylinder into multiple cavities, allowing for the drying of multiple pieces of dried bean curd—it lacks a hot air circulation system, resulting in low drying efficiency and making the dried bean curd susceptible to contamination, leading to poor hygiene and safety. Utility Model Content

[0004] The purpose of this invention is to provide a dried bean curd drying device with hot air circulation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dried bean curd drying device with hot air circulation, comprising a drying chamber and a circulation component.

[0006] Furthermore, a movable frame is engaged with the inner outer end of the fixed frame, and an auxiliary handle is installed on the right surface of the movable frame.

[0007] Furthermore, a nano-sterilization layer is provided on the left end of the inner surface of the active frame, and an activated carbon adsorption layer is installed on the inner surface of the active frame.

[0008] Furthermore, a fine-mesh filter screen is provided on the right end of the inner surface of the movable frame, and the movable frame is an integral structure, with an exhaust fan provided inside the accommodating frame.

[0009] Furthermore, the front hinge of the drying oven is connected to a sealed door, and the surface of the sealed door is provided with a glass observation window, and the rear surface of the sealed door is provided with a sealing strip.

[0010] Furthermore, the surface of the support base is provided with a movable component for uniform drying, and the movable component includes a fixed cavity, a cooling fan, a stepper motor and a movable upright, with the fixed cavity disposed on the surface of the support base.

[0011] Furthermore, a cooling fan is installed on the lower side of the fixed cavity, and a stepper motor is installed inside the fixed cavity. The output end of the stepper motor is connected to a movable upright through a coupling.

[0012] Furthermore, the movable component also includes a support crossbar and a limiting ring, and the support crossbar is installed on the surface of the movable upright.

[0013] This utility model provides a dried bean curd stick drying device with hot air circulation, which has the following beneficial effects:

[0014] 1. This utility model incorporates a circulation component, which includes an electric heating element, a sealing partition, a drying fan, a movable frame, an auxiliary handle, a nano-sterilization layer, an activated carbon adsorption layer, a fine-mesh filter, and an exhaust fan. During use, the drying fan draws outside air into the drying chamber. During air intake, the fine-mesh filter intercepts and filters fine impurities such as dust, preventing them from entering the drying area and ensuring clean hot air. The activated carbon adsorption layer adsorbs odors and harmful substances from the air, improving the drying environment and enhancing the quality of the dried bean curd. The nano-sterilization layer utilizes nanotechnology to kill bacteria and microorganisms in the air. To ensure hygiene and safety during the drying process, purified air is heated by an electric heating element to create hot air for drying the dried bean curd sticks. Simultaneously, an exhaust fan removes moisture and waste gas from the equipment, maintaining a dry and well-ventilated drying environment and creating internal hot air circulation. An auxiliary handle allows the movable frame to be disassembled for cleaning or replacement of the nano-sterilization layer, activated carbon adsorption layer, and fine-pore filter. This enables the device to achieve efficient hot air circulation and provides multiple functions including sterilization, adsorption, and filtration, improving drying efficiency and bean curd stick quality while ensuring hygiene and safety throughout the production process.

The movable component also includes a supporting crossbar and a limiting ring. In use, the dried bean curd sticks are hung on the supporting crossbar, and the limiting rings provide spaced positioning. The stepper motor is then started, causing the movable upright to rotate. This, in turn, causes the supporting crossbar and limiting ring to rotate at a uniform speed, facilitating even drying of the dried bean curd. During the drying process, the cooling fan continuously dissipates heat from the fixed cavity, preventing the stepper motor from overheating and being damaged. This allows the device to achieve uniform drying of the dried bean curd, improving processing efficiency and quality. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3As shown, a dried bean curd drying device with hot air circulation includes a drying chamber 1 and a circulation component 5. A support base 2 is installed on the lower side of the drying chamber 1, and a fixed frame 3 is provided on the right side of the drying chamber 1. A receiving frame 4 is installed on the upper side of the drying chamber 1. The circulation component 5 is disposed on the surface of the fixed frame 3 and includes an electric heating tube 501, a sealing partition 502, a drying fan 503, a movable frame 504, an auxiliary handle 505, a nano-sterilization layer 506, an activated carbon adsorption layer 507, a fine-mesh filter 508, and an exhaust fan 509. The electric heating tube 501 is disposed on the inner end of the inner surface of the fixed frame 3, and the fixed frame... The inner surface of the fixed frame 3 is provided with a sealing partition 502. The sealing partition 502 and the fixed frame 3 are an integrated structure that is tightly connected. A drying fan 503 is installed on the surface of the sealing partition 502. A movable frame 504 is engaged with the outer end of the inner side of the fixed frame 3. An auxiliary handle 505 is installed on the right surface of the movable frame 504. A nano sterilization layer 506 is provided on the left end of the inner surface of the movable frame 504. An activated carbon adsorption layer 507 is installed on the inner surface of the movable frame 504. A fine-mesh filter screen 508 is provided on the right end of the inner surface of the movable frame 504. The movable frame 504 is an integrated structure. An exhaust fan 509 is provided inside the accommodating frame 4.

[0022] The specific operation is as follows: When in use, start the drying fan 503 to draw outside air into the drying chamber 1. During the air intake process, the fine impurities such as dust from the outside are intercepted and filtered by the fine-mesh filter 508 to prevent them from entering the drying area and ensure the cleanliness of the hot air. The activated carbon adsorption layer 507 adsorbs odors and harmful substances in the air, improves the drying environment, and enhances the quality of the dried bean curd. The nano-sterilization layer 506 can use nanotechnology to kill bacteria and microorganisms in the air, ensuring the hygiene and safety of the drying process. The purified air is heated by the electric heating tube 501 to form hot air for drying the dried bean curd. At the same time, the exhaust fan 509 discharges moisture and exhaust gas from the equipment to maintain the dryness and ventilation of the drying environment and form an internal hot air circulation. The movable frame 504 can be disassembled with the help of the auxiliary handle 505 to facilitate the cleaning or replacement of the nano-sterilization layer 506, the activated carbon adsorption layer 507, and the fine-mesh filter 508.

[0023] Please refer to Figure 1 and Figure 3The drying oven 1 has a front hinge connected to a sealing door 6, and the surface of the sealing door 6 is provided with a glass observation window 7. The rear surface of the sealing door 6 is provided with a sealing strip 8. The surface of the support base 2 is provided with a movable component 9 for uniform drying. The movable component 9 includes a fixed cavity 901, a cooling fan 902, a stepper motor 903, and a movable upright 904. The fixed cavity 901 is provided on the surface of the support base 2. The cooling fan 902 is installed on the lower side of the fixed cavity 901. The stepper motor 903 is installed inside the fixed cavity 901. The output end of the stepper motor 903 is connected to the movable upright 904 through a coupling. The movable component 9 also includes a support crossbar 905 and a limiting ring 906. The support crossbar 905 is installed on the surface of the movable upright 904. The limiting ring 906 is provided on the surface of the support crossbar 905. The limiting ring 906 and the support crossbar 905 are a tightly connected integrated structure.

[0024] The specific operation is as follows: When using, hang the dried bean curd sticks on the support crossbar 905, and use the limiting ring 906 to limit the spacing of the dried bean curd sticks. Start the stepper motor 903, so that the stepper motor 903 drives the movable upright 904 to rotate. The movable upright 904 drives the support crossbar 905 and the limiting ring 906 to rotate at a uniform speed, so as to facilitate uniform drying. During the drying process, the cooling fan 902 continuously dissipates heat from the inside of the fixed cavity 901 to prevent the stepper motor 903 from being damaged due to overheating.

[0025] In summary, as Figures 1 to 3As shown, this hot air circulating dried bean curd drying equipment operates as follows: First, the bean curd is hung on the support crossbar 905, and the bean curd is spaced out by the limiting ring 906. Then, the stepper motor 903 is started, causing the movable upright 904 to rotate. The movable upright 904, in turn, causes the support crossbar 905 and the limiting ring 906 to rotate at a uniform speed, facilitating even drying. During the drying process, the cooling fan 902 continuously dissipates heat from the fixed cavity 901 to prevent the stepper motor 903 from overheating and being damaged. Finally, the drying fan 503 is started, drawing outside air into the drying chamber 1. During the air intake process, fine impurities such as dust are filtered through the dense filter screen 508. To prevent odors from entering the drying area and ensure clean hot air, the activated carbon adsorption layer 507 adsorbs odors and harmful substances in the air, improving the drying environment and enhancing the quality of the dried bean curd. The nano-sterilization layer 506 uses nanotechnology to kill bacteria and microorganisms in the air, ensuring a hygienic and safe drying process. The purified air is heated by the electric heating tube 501 to form hot air for drying the dried bean curd. At the same time, the exhaust fan 509 discharges moisture and exhaust gas from the equipment, maintaining a dry and ventilated drying environment and forming an internal hot air circulation. The movable frame 504 can be disassembled with the help of the auxiliary handle 505 to facilitate cleaning or replacement of the nano-sterilization layer 506, the activated carbon adsorption layer 507, and the fine-mesh filter 508.
