After the wet blank of the product is made, the product is firstly stacked in a natural drying area, and natural wind is introduced to realize the first natural pre-drying, thereby playing the advantages of natural drying and energy saving and achieving a certain dehydration effect. When the pre-air-dried product blank reaches a certain drying state, the blank is hoisted by the hoisting and lifting device to the product conveying device of the manual drying hole below the blank, enters one end of the drying hole and travels, and then secondary manual drying with a heat source is carried out. The dried product comes out of the other end of the drying hole along with the conveying device and is taken away for transportation.

The natural drying area can also be provided with a conveying device for the products to move horizontally along the length direction of the drying hole, and the conveying device can be in a form of a drying vehicle and a track or a plate chain conveyor.

After the wet blank of the product is made, the product is stacked on a drying vehicle in a natural drying area, and slowly moves forward from the initial section of the natural drying area along the length direction of the drying hole, so that the first natural pre-drying is realized in the walking process. When the pre-air-dried product blank is conveyed to the end of a natural drying area by the drying vehicle, the lifting and lifting device lifts the product and the drying vehicle to a track of the artificial drying hole below the product and the drying vehicle, the product and the drying vehicle enter one end of the drying hole and travel, and further secondary artificial drying with a heat source is carried out. The dried product comes out from the other end of the drying hole and is taken away for transferring, or is hoisted along with the drying vehicle, the product is taken away for transferring on the upper layer, the empty drying vehicle returns to the initial product wet blank stacking position, and a new product wet blank is continuously stacked, so that circulation is realized.

The drying production line utilizes the energy-saving advantage of natural drying, takes away a large amount of moisture in the product through air circulation, reduces the moisture amount needing drying in the subsequent drying holes, saves energy consumption, can greatly reduce the length of the drying section of the drying holes, and does not occupy more fields and spaces. Meanwhile, the natural drying track above the drying hole and the track in the drying hole form a three-dimensional circulating system, so that the occupied area is reduced, a large number of no-load drying vehicles are saved, and high-yield and automatic continuous production is realized by using limited energy and facilities. Particularly, the sintering kiln sinking below the ground can be set to be that the natural drying area is positioned on the ground, the artificial drying hole and the sintering kiln are positioned on the same horizontal layer below the ground, and the dried product is directly transferred to the sintering kiln, so that the operation is more convenient, and the field is more fully utilized.

The natural drying area can be provided with a fan to take away more moisture by enhancing air circulation.

In addition, the hoisting and lifting device can be a cantilever crane, a traveling crane, a lifter and a robot; the method can be special or shared with other processes, such as brick holding machine.
