Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features. Thus, the definition of "a first", "a second" feature may explicitly or implicitly include one or more of such feature, and in the description of the present utility model, the meaning of "a number", "a number" is two or more, unless otherwise specifically defined.

The utility model provides a loading hopper with stoving function, includes hopper 1 and (mixing) shaft 3 of tube-shape, is provided with a plurality of stirring leaf 31 on the (mixing) shaft 3, be provided with blow pipe 2 on the hopper 1, be provided with a plurality of gas pockets 21 on the blow pipe 2, gas pockets 21 are inside towards hopper 1, blow pipe 2 is connected with the air heater.

In this embodiment, a dehumidifier may be further connected before the preferred air heater to ensure that the air entering the air heater is dry air, and of course, if the air is low humidity air in the processing site, the air may be directly extracted without the dehumidifier.

Wherein the stirring shaft 3 is connected with a stirring motor which may be arranged above the hopper 1 for driving rotation of the stirring shaft 3, wherein the connection and arrangement of the stirring motor and the stirring shaft 3 may be as disclosed in prior art CN 205467195U.

When the device works, air is heated by the hot air blower and is sent into the air blowing pipe 2, the dried hot air is sprayed out through the air holes 21 and is blown to raw materials in the hopper 1, the raw materials are dried and heated, and the hot air containing water vapor moves upwards to the outside of the hopper 1 to carry the water vapor out; simultaneously, the stirring shaft 3 and the stirring blades 31 continuously stir the raw materials in the hopper 1 under the drive of the stirring motor, so that the raw materials are heated and dried more uniformly.

In this embodiment, the air blowing pipes 2 are preferably arranged along the circumference of the hopper 1, the air holes 21 are uniformly distributed along the circumference, and as shown in fig. 1, the dried hot air is sprayed to the inside of the hopper 1 along the circumferential direction of the hopper 1, so that the raw materials in the hopper are uniformly dried.
