[0002] At present, fish products are deeply processed, rinsed, de-impurified and disinfected before being put into a dryer for drying. Drying is generally carried out in a drying box, and a convection thermal drying method is generally adopted, that is, a heat source is used to heat the air in the drying room, and the hot air is convected with the help of wind power to heat the wet fish and take away the moisture in the wet fish. Wet fish drying requires heat, and heat is used for heat exchange. Only after absorbing heat can the wet fish vaporize its own moisture and discharge it to achieve the purpose of drying. In the existing production and drying of fish products, the use of dryers requires manpower to continuously add a fixed amount of wet fish to the drying room at fixed drying times. In actual processing, the cost is high and the drying time is long, and it is not conducive to the needs of large-scale continuous drying.

[0004] However, when the above patent is in use, when the fish products are conveyed on the conveyor belt to the drying box for drying, the bottom of the fish products in contact with the conveyor belt will stick to the conveyor belt due to water loss. Then, when the fish products are taken out from the conveyor belt, part of the fish products will remain on the conveyor belt, resulting in incomplete fish products, reducing the quality of drying of the fish products. At the same time, the fish product debris adhering to the conveyor belt will also clog the through holes on the conveyor belt, affecting the subsequent drying effect of the fish products on the conveyor belt.

[0024] like Figure 1 As shown, in order to facilitate the addition or cleaning of the liquid storage tank 3, a lifting cylinder 301 is fixedly connected to the bottom of the drying box 1, and a lifting plate 302 is fixedly connected to the output end of the lifting cylinder 301. The liquid storage tank 3 is placed on the lifting plate 302, and the lifting plate 302 is driven downward by the lifting cylinder 301, and the lifting plate 302 drives the liquid storage tank 3 to move downward, so as to facilitate the removal of the liquid storage tank 3 from the position of the coating roller 5, and then adjust the edible oil or clean it.

[0025] like Figure 1 and Figure 3 As shown, a scraper 6 is connected to the inner wall of one side of the drying box 1, and one end of the scraper 6 cooperates with the smear roller 5 to leave a certain gap, so as to facilitate the scraping of the edible oil attached to the outer wall of the smear roller 5, and avoid excessive edible oil attached to the outer wall of the smear roller 5, and an adjusting rod 601 is threadedly connected to the outer wall of the drying box 1, and one end of the adjusting rod 601 located inside the drying box 1 is rotatably connected to the scraper 6, and a limiting plate 602 is fixedly connected inside the drying box 1, and the bottom of the scraper 6 is in contact with the limiting plate 602. By rotating the adjusting rod 601, the adjusting rod 601 drives the scraper 6 to contact the limiting plate 602 for limited movement, thereby adjusting the distance between the end of the scraper 6 and the smear roller 5, so as to facilitate the control of the amount of edible oil attached to the outer wall of the smear roller 5.

[0026] like Figure 1As shown, in order to ensure uniformity in drying both sides of the fish products, two groups of support frames 701 are fixedly connected to the inner wall of the drying box 1, and the two groups of support frames 701 are respectively located on the upper and lower sides of the belt surface of the conveyor belt 2, so that the fish products on the conveyor belt 2 are dried from the upper and lower sides of the conveyor belt 2, and there are two groups of heating racks 7, which are arranged on the two groups of support frames 701. By opening the box door 101 on one side of the drying box 1, and then sliding the heating rack 7 on the support frame 701 to take out, it is convenient to clean the water vapor and grease generated by drying the fish products on the heating rack 7, thereby reducing the residual fishy smell inside the drying box 1.

[0027] like Figure 1 and Figure 4 As shown, in order to facilitate the removal of moisture from fish products of different sizes, two sets of connecting plates are fixedly connected to one side of the drying box 1 in the above-mentioned embodiment, and a slide groove is provided on the side wall of the connecting plate. A slider 901 is slidably connected inside the slide groove. Both ends of the water-absorbing roller 9 are rotatably connected to the slider 901. A spring 902 is provided inside the slide groove to abut against the slider 901. When the conveyor belt 2 transports larger fish products, the water-absorbing roller 9 is driven to move upward by the slider 901 to facilitate the passage of the fish products. At the same time, the tension of the spring 902 pushes the water-absorbing roller 9 downward to keep the water-absorbing roller 9 against the water-absorbing roller 9.
