The utility model has the positive effects that the air volume of the draught fan is larger than that of the air blower, so that the cooling scraper conveyor works under the micro negative pressure, the inner surface of the shell is kept dry and free from dewing, and dust is prevented from overflowing; because the adopted air blower and the induced draft fan are low and medium pressure fans, the air supply and dust removal pipelines are short, the consumed power ratio is small, and the conveying power of the cooling scraper conveyor is small, the power consumption of the whole system is reduced by more than two thirds than that of a pneumatic conveying cooling mode, and the operation cost is greatly reduced; the motors of the air blower and the induced draft fan are controlled by frequency conversion, and are reasonably adjusted according to the environmental temperature change in four seasons, so that the cooling effect is optimal, and the electric energy consumption is further reduced; the method can be popularized to the feed and biological oil processing industry, replaces a meal cooler, and realizes conveying and cooling of finished meal before packaging.
