Quick freezing is the decisive factor to ensure the quality of products. The faster the freezing speed is, the better the product quality is; on the contrary, the longer the freezing time, the worse the product quality. The suppliers of quick-frozen corn will use fluidized-bed quick freezing tunnel for quick freezing treatment. Corn kernels are laid flat on the conveyor belt, there are many typhoons under the conveyor belt. At the speed of 6 ~ 8 m / s, the cold air is blown down to up to make the corn grain in suspension, the temperature in the center of corn kernel can reach - 18C. The corn kernels should adhere to each other have no frost on the surface. If the evaporation temperature of the machine is - 34 ~ - 40C, the cold air temperature is - 26 ~ - 30C, the thickness of corn kernels is 80 ~ 38mm, freezing for 8-15 minutes can meet the requirements.
