[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0022] Example:

[0023] A stirring drying oven, such as Figure 1-Figure 2 As shown, it includes a box body 10, in which a plurality of stirring pools 20 are arranged, each stirring pool 20 is respectively provided with a stirring blade 30, and a low-speed stirring motor for driving the stirring blade 30 to rotate is arranged in the box body 10; a heating component 40 is arranged in the box body 10, and the heating component 40 can select an electric heating component 40 such as an electric heating wire or an electric heating plate; an air inlet 11 and an air outlet 12 are respectively arranged on the left and right sides of the box body 10, and the air outlet 12 is conical, and a heating fan 70 connected to the air inlet 11 is arranged outside the box body 10.

[0024] In another embodiment, if Figure 2 As shown, a dehumidification component is also included, which includes a dehumidification box 60 and a desiccant filled in the dehumidification box 60. The desiccant is replaceable. The inlet and outlet of the dehumidification box 60 are respectively connected to the air outlet 12 and the inlet of the heating fan 70 through the circulating air duct 50. The dehumidification component is arranged to dehumidify the hot air discharged from the air outlet 12 and recycle it, so that the gas entering the heating fan 70 for heating can be maintained at a higher initial temperature, making full use of the preheating of the discharged hot air to achieve the purpose of saving energy.

[0025] In another embodiment, if Figure 2 As shown, the inlet height of the heating fan 70 is higher than the outlet height of the dehumidification box 60, which is conducive to the condensation of the unabsorbed water vapor in the dehumidification box 60 in the inclined circulation air duct 50 and the reflux to the dehumidification box 60 for re-adsorption.

[0026] In another embodiment, if Figure 2 As shown, one end of the circulating air duct 50 connected to the inlet of the dehumidification box 60 has a rising pipe section, and the lowest end of the rising pipe section is connected to the drain pipe 51. After the hot air discharged from the air outlet 12 enters the circulating air duct 50, the temperature drops, and part of the water vapor will condense into liquid water in the circulating air duct 50. The provision of the rising pipe section can prevent this part of the liquid water from entering the dehumidification box 60 and can be discharged through the drain pipe 51. In this way, the dehumidification effect of the dehumidification box 60 on the circulating hot air can be improved.

[0027] In another embodiment, the stirring blades 30 in the plurality of stirring tanks 20 are independently driven by a group of low-speed stirring motors.

[0028] In another embodiment, if Figure 2 As shown, the low-speed stirring motor is located at the bottom of the stirring tank 20 and is embedded in the bottom wall of the box body 10, and the stirring blade 30 is keyed to the shaft of the low-speed stirring motor, which is convenient for disassembly, cleaning and maintenance.

[0029] In another embodiment, if Figure 2 As shown, a plurality of heating components 40 are provided, and the plurality of heating components 40 are evenly distributed on the inner wall of the box body 10 and are located above the pool opening of the stirring pool 20 .

[0030] In another embodiment, a box door is provided on one side wall of the box body 10, and a transparent observation window is provided on the box door to facilitate observation of the drying state of the material.

[0031] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
