[0028] In order to make those skilled in the art better understand the technical solution of the utility model, the utility model will be described in detail below in combination with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.
[0029] As Figures 1-5As shown, a continuous drying device for processing dried beancurd sheets, comprising a drying channel 1, both ends of the drying channel 1 are provided with openings, heating elements are arranged on the inner top surface and the inner bottom surface of the drying channel 1, and ventilation elements are arranged on the side wall of the drying channel 1. In use, the heating elements on the inner top surface and the inner bottom surface of the drying channel 1 are heated, and at the same time, the ventilation elements on the side wall are ventilated to realize the hot air circulation of the inner wall of the drying channel 1. The drying disc 4 is provided with a hollow structure, and the drying disc 4 is rotatably connected to the inside of the drying channel 1. A conveyor belt 5 for conveying dried beancurd sheets is arranged above the drying disc 4. One end of the conveyor belt 5 is provided with a conveying plate 6 that is inclined downward from the conveyor belt 5 to the drying disc 4. The conveying plate 6 is used to lay dried beancurd sheets on the drying disc 4. A scraper 7 is arranged on the conveying plate 6, and the bottom of the scraper 7 is attached to the drying disc 4. The scraper 7 is used to scrape dried beancurd sheets from the drying disc 4. A driving element is used to drive the drying disc 4 to rotate slowly. In use, the dried beancurd sheets that need to be dried are transferred along the conveying plate 6 to the drying disc 4 through the conveyor belt 5 in the previous processing step, and are evenly laid on the drying disc 4. Then the driving element drives the drying disc 4 to rotate, and the dried beancurd sheets enter from the inlet of the drying channel 1. Then the heating elements on the inner top surface and the inner bottom surface of the drying channel 1 heat the two sides of the dried beancurd sheets evenly, causing the water on the surface of the dried beancurd sheets to evaporate. At the same time, the ventilation elements ventilate from the side wall of the drying channel 1 to accelerate the hot air circulation inside the drying channel 1. Finally, the drying disc 4 comes out of the outlet of the drying channel 1 from the other end, is scraped off by the scraper 7, and is collected. Through the slow rotation of the drying disc 4, the dried beancurd sheets in different parts are heated evenly, and the efficiency of drying the dried beancurd sheets is improved.
[0030] Further, the heating elements are a plurality of heating pipes 2, which are evenly arranged on the inner top surface and the inner bottom surface of the drying channel 1. The heating pipes 2 can be stainless steel heating pipes, carbon fiber heating pipes 2, etc. The former is cheap, easy to use and pollution-free, and the latter has high electric heating conversion efficiency, uniform heating and long service life. By evenly arranging the heating pipes 2 in the drying channel 1, the dried beancurd sheets laid on the drying disc 4 can be evenly heated, improving the drying efficiency of the dried beancurd sheets.
[0031] Furthermore, the ventilation component includes multiple ventilation fans 3, and the multiple ventilation fans 3 can be detachably connected to the side walls at both ends and the middle side wall of the drying channel 1, wherein the ventilation fans 3 can be fixed to the side walls of the drying channel 1 by screws, clamping, etc. In addition, the ventilation fans 3 are arranged on the side walls at both ends and the middle side wall of the drying channel 1, which is equivalent to dividing the drying channel 1 into three parts when in use. When the bean curd sheets enter from the entrance of the drying channel 1, due to the entrance of the drying channel 1 and the setting of the ventilation fans 3, the initial temperature is relatively low, which avoids the rapid crusting of the surface of the bean curd sheets and affects the internal moisture dissipation. Then, as the bean curd sheets enter the Hongang channel, the temperature becomes higher, which can accelerate the evaporation of moisture. Then, when the bean curd sheets are about to come out, the temperature at the outlet of the drying channel 1 becomes lower, and the final moisture balance is performed, thereby ensuring the drying efficiency.
[0032] Furthermore, the driving part includes a rotating rod 801 and a motor 802. A base 9 is provided at the bottom of the drying channel 1. The motor 802 is arranged in the base 9. The output end of the motor 802 is connected to the rotating rod 801. One end of the rotating rod 801 extends to the interior of the drying channel 1 and passes through the drying tray 4. The rotating rod 801 is rotatably connected to the drying channel 1. The motor 802 is a reduction motor 802, which can provide a uniform and relatively slow rotation speed. When in use, the motor 802 drives the rotating rod 801 to rotate slowly, and then the rotating rod 801 drives the drying tray 4 to rotate slowly. At the same time, the rotating rod 801 passes through the drying tray 4, dividing the drying tray 4 into an annular drying area, avoiding the bean curd sheets just placed on the drying tray 4 from contacting the bean curd sheets that are in the drying process, and avoiding moisture transfer between them.
[0033] Furthermore, connecting rods 10 are provided on both sides of the lower end of the conveying plate 6, and a movable plate 11 is hinged between the two connecting rods 10. When the drying tray 4 rotates and the bean curd sheets contact the movable plate 11, the movable plate 11 can gently flatten the bean curd sheets, allowing the bean curd sheets to be spread on the drying tray 4 in a better posture.
[0034] Furthermore, it also includes a collecting component, which includes an inclined plate 1201 and a collecting box 1202 connected to the bottom of the inclined plate 1201. The top of the inclined plate 1201 is located below the drying tray 4. The dried bean curd sheets touch the scraper 7 and are then scraped off by the scraper 7. The scraped bean curd sheets fall along the inclined plate 1201 into the collecting box 1202 and are collected.
[0035] The working principle and use process of the utility model: when using the device, first, the conveyor belt 5 conveys the dried beancurd sticks needing drying after the previous step to the drying disc 4 through the conveying plate 6, and then evenly lays on the drying disc 4, the motor 802 drives the rotating rod 801 to rotate, the rotating rod 801 drives the drying disc 4 to rotate, then the beancurd sticks pass through the movable plate 11, are laid flat by the movable plate 11, and enter through the inlet of the drying channel 1, then the heating pipe 2 heats the beancurd sticks, evaporates the moisture on the surface of the beancurd sticks, simultaneously, the ventilating fan 3 accelerates the hot air circulation in the drying channel 1, when the rotating disc rotates a circle, the beancurd sticks at the beginning come out from the outlet of the drying channel 1, the dried beancurd sticks contact the scraper 7, are scraped off by the scraper 7, and drop into the collecting box 1202 along the inclined plate 1201 and are collected.
