The mode that the axial direction of the stirring shaft 121 is perpendicular to the axial direction of the bin body 110 is convenient for arranging the spiral stirring blade 122 close to the discharge port 111, so that pills near the discharge port 111 can be fully stirred; at the same time, the tangential force generated by the helical mixing blade 122 during mixing is advantageous to assist the pellets in passing through the discharge port 111.
As an example, the stirring shaft 121 is disposed at the bottom of the inner cavity of the bin body 110.
The hot air drying mechanism 130 includes a hot air duct 131 and a heating member 133. The hot air duct 131 is connected to the bin body 110, and the heating member 133 is disposed at an air inlet end of the hot air duct 131 for heating air at the air inlet end of the hot air duct 131 so as to provide hot air into the hot air duct 131.

Under the mode of introducing hot air into the inner cavity of the bin body 110 through the vent 1211 on the stirring shaft 121, the vent 1211 has a large distribution range in the inner cavity of the bin body 110, so that the hot air is conveniently and uniformly introduced into the inner cavity of the bin body 110 in a large amount to achieve better drying.
It is understood that, in order to ensure that the vent 1211 can smoothly pass the hot air in the vent cavity to the outside into the inner cavity of the cartridge body 110, the vent 1211 can be provided with an anti-blocking structure in a manner known in the art.
As an example, the aperture of the vent 1211 is controlled to be smaller than the particle size of the pellet, so as to effectively prevent the pellet from blocking the vent 1211 and ensure that the vent 1211 can vent smoothly.
The problem of caking of pellets in the silo can be improved well by the stirring action of the stirring mechanism 120, considering that the moisture content of the pellets does not have a significant effect on the caking problem when the moisture content of the pellets is low.
Therefore, in order to more conveniently control the hot air drying mechanism 130 to start and stop drying the pellets in the inner cavity of the bin body 110 as required, optionally, the hot air duct 131 is provided with an electrically controlled intake valve 132, and the opening and closing of the hot air duct 131 can be effectively controlled by the electrically controlled intake valve 132, so that the hot air duct 131 has a ventilating state and an air-stopping state.
