Description
Technical Field
[0001] The utility model relates to the technical field of dried tofu processing, and more specifically, to a rapid air-drying device for processing dried mushroom tofu. Background Art
[0002] Dried tofu with shiitake mushrooms is a packaged food made of shiitake mushrooms and dried tofu as the main ingredients. During the production process of dried tofu with shiitake mushrooms, the mushrooms need to be air-dried. Therefore, it is inevitable that the dried tofu needs to be placed in a tray or other equipment. Natural wind or a blower is used to continuously pass through the dried tofu and remove moisture from its surface, thereby achieving the purpose of air drying.
[0003] However, the side of the dried tofu placed on the tray that contacts the tray is difficult to contact with the airflow, and the moisture on its surface is difficult to dry quickly. Most of the moisture needs to penetrate into the upper surface of the dried tofu to be carried away by the airflow, which greatly reduces the drying rate of the dried tofu. Therefore, it needs to be improved. Utility Model Content

[0026] The placement rack 3 includes two left and right mesh clamps 31, the lower ends of the two mesh clamps 31 are movably hinged, the upper ends of the two mesh clamps 31 are clamped to each other, and a gap is left between the two mesh clamps 31. A clamping slot 32 is provided in the front and back of the two mesh clamps 31, and a rotating clamping shaft 33 is slidably clamped inside the clamping slot 32, and the rotating clamping shaft 33 is fixedly connected to the transmission shaft 4; due to the setting of the rotating clamping shaft 33, the reciprocating transmission mechanism can drive the multiple mesh clamps 31 and the dried tofu inside them to swing back and forth continuously with the cooperation of the transmission shaft 4, so that the left and right sides of the mesh clamps 31 can alternately contact the airflow in the valve cavity 12 below them, so that the left and right sides of the dried tofu are alternately in contact with the drying airflow, greatly improving the drying rate of the dried tofu.
[0027] The gap between the two mesh clamps 31 is smaller than the thickness of the dried tofu, and the rotating clamping shaft 33 slides up and down along the inside of the clamping slot 32. The transmission shaft 4 drives the mesh clamps 31 to swing left and right as a whole through the rotating clamping shaft 33.
[0028] Among them, the driving mechanism includes a driving motor 8 installed on the back of the air drying box 1, the front end of the output shaft of the driving motor 8 is fixedly connected to the transmission component 9, a first linkage frame 6 is arranged above the transmission component 9, and several swing arms 5 are arranged in front of the first linkage frame 6.
[0029] Among them, several swing arms 5 correspond to the placement racks 3 one by one, the upper end of the swing arm 5 is fixedly connected to the transmission shaft 4 on the back of the placement rack 3, and a linkage slide groove 7 is opened on the back of the swing arm 5. A linkage slider 15 is movably installed in the linkage slide groove 7, and the rear end of the linkage slider 15 passes through the linkage slide groove 7 and is fixedly connected to the first linkage rack 6.
[0030] Among them, the transmission assembly 9 includes a crank pulley 91 fixedly connected to the output shaft of the driving motor 8, and a second linkage frame 92 is provided on the front of the crank pulley 91. The top of the second linkage frame 92 is fixedly connected to the first linkage frame 6. The second linkage frame 92 and the first linkage frame 6 are slidably connected to the drying box 1 as a whole. A limiting groove is provided inside the second linkage frame 92, and a crank wheel 93 is slidably installed in the limiting groove. The rear end of the crank wheel 93 passes through the limiting groove and is fixedly connected to the crank pulley 91. The crank wheel 93 is located at the edge of the crank pulley 91; due to the setting of the crank wheel 93, when the crank pulley 91 rotates, the second linkage frame 92 and the first linkage frame 6 can be driven to slide continuously left and right through the crank wheel 93, and then the linkage slider 15 and the swing arm 5 are used to drive the several transmission shafts 4 to rotate left and right, so that the placement rack 3 swings left and right.
[0031] Among them, an air inlet hole 10 is provided at the bottom of the air drying box 1, and a dispersion chamber 11 located at the top of the air inlet hole 10 is provided inside the air drying box 1. The interior of the air drying box 1 is also provided with a number of constant pressure valves located between the air drying chamber 2 and the dispersion chamber 11 and evenly distributed. The constant pressure valves correspond one-to-one to the placement rack 3 and are located directly below the placement rack 3. The upper and lower ends of the constant pressure valves are respectively connected to the air drying chamber 2 and the dispersion chamber 11. After the air flow is injected through the air inlet hole 10, the air drying air flow can be brought into contact with the dried tofu from bottom to top, thereby achieving the air drying effect. At the same time, since the air flow is discharged from the top of the air drying chamber 2, dust in the air can be prevented from falling onto the mesh clamping plate 31 and the dried tofu inside it.
[0032] Among them, the constant pressure valve includes several valve chambers 12 opened inside the air-drying box 1 and located between the air-drying chamber 2 and the dispersion chamber 11.

The interior of the valve chamber 12 is also provided with a positioning spring 14 located at the top of the valve block 13. The upper and lower ends of the positioning spring 14 are respectively connected to the inner cavity of the valve chamber 12 and the top of the valve block 13; due to the setting of the constant pressure valve, with the cooperation of the positioning spring 14, several valve blocks 13 are simultaneously blocked by several valve chambers 12. Therefore, when a certain air pressure is reached in the dispersion chamber 11, several valve blocks 13 are simultaneously separated from their corresponding valve chambers 12 and the corresponding positioning springs 14 are compressed, so that the dispersion chamber 11 can enter the air-drying chamber 2 through several valve chambers 12 at the same time, so that several placement racks 3 and the dried tofu inside them are simultaneously exposed to the air-drying airflow, achieving a uniform air-drying effect.
[0033] The working principle and use process of this utility model:
[0034] Spread the dried tofu evenly between the two mesh clamps 31, snap the two mesh clamps 31 together to clamp the dried tofu, and then use the clamping slots 32 to clamp the mesh clamps 31 onto the rotating clamping shaft 33. In this way, all the mesh clamps 31 are placed in the air-drying chamber 2.
[0035] Then the driving motor 8 is started to drive the transmission assembly 9 to rotate. Due to the rotation of the transmission assembly 9, the second linkage frame 92 can be driven to move back and forth continuously horizontally through the crank wheel 93 under the restriction of the air drying box 1, thereby driving the first linkage frame 6 to move back and forth horizontally. Under the cooperation of the swing arm 5 and its internal linkage slide 7, the first linkage frame 6 can simultaneously drive the plurality of swing arms 5 to move through the linkage sliders 15. Since the upper end of the swing arm 5 is restricted by the transmission shaft 4, the first linkage frame 6 drives the lower ends of the plurality of swing arms 5 to swing left and right at the same time through the linkage sliders 15, thereby driving the plurality of transmission shafts 4 to rotate back and forth continuously. Furthermore, under the cooperation of the card slot 32, the transmission shaft 4 drives the mesh clamping plate 31 as a whole to swing left and right continuously through the rotating card shaft 33, so that the left and right sides of the mesh clamping plate 31 as a whole alternately contact the airflow in the valve chamber 12 below it.
[0036] When the drying airflow entering from the air inlet 10 enters the dispersion chamber 11 and reaches a certain air pressure, it pushes the valve block 13 and compresses the positioning spring 14 with the cooperation of the valve chamber 12, so that the valve block 13 can be separated from the valve chamber 12, so that the upper and lower ends of the valve chamber 12 are connected to the drying chamber 2 and the dispersion chamber 11 respectively. At this time, the airflow in the dispersion chamber 11 can enter the interior of the drying chamber 2 through several valve chambers 12 at the same time, so that several mesh plywood 31 and the dried tofu inside them can receive the drying airflow at the same time.
