In this embodiment, specifically, the U-shaped circulation pipe 71 is bolted to the middle position in front of the right side of the drying box 1 and is communicated with the inside of the drying box 1.

In this embodiment, specifically, the left side of the L-shaped hanging rod 85 is hung inside the hanging groove 86; the rotation groove 84 and the hanging groove 86 are correspondingly arranged.

In this embodiment, specifically, the connecting seat 81 is installed at the middle position of the right side of the front surface of the first shutter door 11 through a hexagon socket bolt 83; the hanging seat 82 is arranged at the middle position of the left side of the front surface of the second shielding door 12 through a hexagonal socket bolt 83; the hexagonal socket bolts 83 are respectively in threaded connection with the middle position of the right side of the front surface of the first shielding door 11; the hexagonal socket bolt 83 is further screwed to the middle position on the left side of the front surface of the second shutter door 12.

Principle of operation

In the invention, when the agricultural product drying work is carried out, the drying box 1 is pushed to move, the drying box 1 is moved to a proper position and fixed, then an external power supply is connected by using an external lead, then the first shielding door 11 and the second shielding door 12 are respectively opened, the agricultural products are respectively placed at the upper end of the placing disc 9, then the external power supply is opened, the heating component 54 and the power fan component 57 start to work, air around the heating component 54 is blown downwards by the power fan component 57 to carry out heat-seal drying work on the agricultural products, hot air is blown into the inside of the heat dissipation box 61 by the power fan component 57 in the process of heat-seal drying of the agricultural products, then the hot air enters the inside of the drying box 1 through the air outlet 62 to carry out the heat-seal drying work on the agricultural products, moisture in hot air is absorbed by the conical adsorption block 66 in the process of conveying the hot air, and the dehumidification work is, carry out dry in-process at agricultural product and make steam carry out cycle work in the inside of stoving case 1 through U type circulating pipe 71, it is even that the convenience makes agricultural product be heated at steam endless in-process, prevent that the agricultural product is heated inhomogeneous and influences the machining efficiency of agricultural product at work, close first shutter door 11 and second shutter door 12 at the in-process that carries out hot air drying to agricultural product, then rotate L type articulate lever 85, make L type articulate lever 85's left side articulate and hide door 11 and second shutter door 12 and carry out fixed work at the inside of articulate groove 86, prevent to run out the machining speed that influences agricultural product at the hot-blast of work, observe the processing progress of piece 14 observation agricultural product through first observation piece 13 and second simultaneously at work, the convenience increases the observation function at work, and then accomplish work.
