Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, in an embodiment of the present invention, a polypropylene particle hot air dryer includes: the air heater comprises a box body 1, a motor 2, an air heater 3, an air pipe 31 and a first rack 22, wherein the motor 2 is arranged on the bottom surface inside the box body 1, the output end of the motor 2 is coaxially connected with a first gear 21, and the first gear 21 is meshed with the first rack 22; the first rack 22 is vertically placed, and the first rack 22 is engaged with the second gear 51 of each row. The air heater 3 is arranged on two sides of the motor 2, the air pipe 31 is arranged above the air heater 3, and the air pipe 31 is connected with an air outlet of the air heater 3 through threads. The thermometer 9 and the hygrometer 91 are arranged at the top of the interior of the box body 1, the thermometer 9 and the hygrometer 91 are used for detecting the temperature and the humidity in the box body 1, and an operator can adjust the air inlet amount of the hot air blower 3 according to the data. The cross-sectional diameter of the upper half of the box body 1 is larger than that of the lower half. The box body 1 is large at the top and small at the bottom, the characteristic that hot air flows upwards is fully utilized, polypropylene particles can be placed on the top as much as possible by the structure, and the drying efficiency is improved. The top of tuber pipe 31 is provided with a plurality of air exit 32 that the interval equals, and the air exit 32 that the interval equals is favorable to the thermally equivalent of polypropylene granule.
