The drying device for dried flower processing according to claim 8, wherein: the grid of the final-stage flow distribution chamber (453) is communicated with the inner cavity of the drying box (1), and the end parts, far away from the exhaust pipe (203) and the air inlet pipe (204), of the two flow distribution pipes (6) correspond to the grid positions of the primary flow distribution chambers (451) of the exhaust flow distribution box (4) and the air inlet flow distribution box (5) respectively.
10. The drying process for the drying device for dried flower processing according to claim 9, wherein: the method comprises the following steps:
s1, paving special gauze or paper towels inside the drying drawer (3), flatly paving the cleaned and drained flowers in the drying drawer (3), and closing the drying box (1);
s2, installing a filter element (208) in the filter box (202), closing the box cover (205), and switching a three-way valve (209) to ensure that the exhaust pipe (203) is communicated with one of the filter chambers (206);
s3, starting a power supply of the drying device, starting the heat tracing device (11) and the low-speed motor (10), heating the air inlet pipe (204) and the air inside the air inlet pipe by the heat tracing device (11), and driving the worm wheel blade (9) to rotate at a low speed by the low-speed motor (10) to drive the heated air to flow;
s4, the heated air enters an air inlet flow distribution box (5) through an air inlet pipe (204) and a flow distribution pipe (6), and the heated air uniformly enters the drying box (1) after being sequentially distributed step by step through grids of a primary flow distribution chamber (451), a plurality of intermediate flow distribution chambers (452) and a final flow distribution chamber (453);
s5, heating air flows from bottom to top in the drying box (1), the evaporation of water on the surface of flowers and in the flowers is accelerated and the air drying is accelerated by air circulation and temperature increase, and the water content in the flowers is gradually increased while the air circulates from bottom to top;
s6, enabling air containing moisture to enter an exhaust diversion box (4) from a drying box (1), enabling the air to sequentially pass through a final diversion chamber (453), a plurality of intermediate diversion chambers (452) and a grid of a primary diversion chamber (451) to be converged step by step, ensuring that air at each part in the orthographic projection area of a drying drawer (3) uniformly circulates, enabling the air to reach a filter cavity (206) through a diversion pipe (6) and an exhaust pipe (203), filtering the moisture-containing air through a filter element (208), and enabling the filtered air accompanied with waste heat to enter an air inlet pipe (204) again to realize circulation;
s7, with the progress of a drying process, the drying degrees of flowers in drying drawers (3) with different heights are different, the flowers in the drying drawer (3) at the bottom are dried firstly to be made into dried flowers and taken out firstly, the flowers in the drying drawer (3) at the upper part are dried later, the drying drawer (3) is moved downwards step by step, the drying drawer (3) for taking out the dried flowers is arranged at the position of a slide rail (102) at the neutral position at the top, the cleaned and drained flowers are tiled, special gauze or paper towels are replaced regularly, and the steps are repeated;
s8, along with the going on of stoving technology, filter core (208) water content on the inside not co-altitude card strip (207) of filter chamber (206) is different, the water content of bottom filter core (208) is the most, take out the change, top filter core (208) water content is less than below filter core (208), downwards move filter core (208) step by step, install dry filter core (208) on top card strip (207), can control and switch three-way valve (209), do not influence the incessant to carrying moisture air when guaranteeing to change filter core (208), high-efficient filtration, regularly open the comdenstion water in outlet pipe (203) is discharged to drain valve (210), so reciprocal.
