The heating pipe 307 in the heating box 305 heats the air and blows the hot air to the aquatic products on the conveying roller 202 through the exhaust nozzle 304. At the same time, the electric heating plate 302 on the heating box 301 is heated to heat the temperature inside the entire heating box 301 to dry the aquatic products. At the same time, the moisture is discharged from the wind collecting hood 308 on the top of the heating box 301 along with the hot air, so as to avoid the moisture liquefying and condensing on the box wall of the heating box 301 and causing it to drip and fall on the aquatic products again, thereby improving the drying efficiency. The hot air passes through the wind collecting hood 308 and the return air The pipe 309 re-enters the heating box 305. In the process of moving from the left side to the right side of the conveying rack 201, the aquatic product is dried by the heating box 301 and blown dry by the exhaust nozzle 304 to evaporate the moisture it carries, and then the dried aquatic product is transported out through the output conveyor belt 5. In the drying process, water dripping from the aquatic product passes through the gap between the conveying rollers 202 and falls into the water collecting tank 403 below, and then passes through the water pipe 404 to the water collecting tank 405, and is then sent to the sewage treatment equipment through a water pump for treatment. When a batch of aquatic products is processed and the equipment is stopped, clean water is sprayed on the conveying roller 202 through the water nozzle 401 to rinse off the blood stains attached to the conveying roller 202, and the sewage falls into the water collecting tank 403, and then enters the water collecting tank 405 for delivery, so as to keep the equipment clean.
