[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0025] Please refer to Figures 1 to 3 , an efficient seed drying device, comprising an air inlet chamber 1 and a first circulation mechanism 2 and a second circulation mechanism 3 symmetrically arranged on the X-direction side and the X-direction reverse side of the air inlet chamber 1;

[0026] The Y-direction side of the air inlet chamber 1 is provided with an air inlet 11 for connecting to a hot air blower;

[0027] The first circulation mechanism 2 includes a seed placement chamber 21, which is surrounded by a housing and a first mesh plate 22 and a second mesh plate 23. The first mesh plate 22 is perpendicular to the X direction, the second mesh plate 23 is perpendicular to the X direction, and the second mesh plate 23 is located on the X direction side of the first mesh plate 22. The seed placement chamber 21 is separated from the air inlet chamber 1 by the first mesh plate 22, and the distance between the second mesh plate 23 and the first mesh plate 22 is 5-20 cm.

[0028] The first circulation mechanism 2 further includes a condensation chamber 24, which is located on the X-direction side of the seed placement chamber 21, and the condensation chamber 24 is separated from the seed placement chamber 21 by a second mesh plate 23; a condensation pipe 241 is provided in the condensation chamber 24;

[0029] The first circulation mechanism 2 further includes a reflux chamber 25, the reflux chamber 25 is located on the X-direction side of the condensation chamber 24, the Y-direction side and the Y-direction reverse side of the upper part of the reflux chamber 25 are respectively connected to the upper part of the air inlet chamber 1 through a reflux pipe 26, and a one-way valve 261 is provided in the reflux pipe 26;

[0030] The upper portion of the seed placement chamber 21 is provided with a feed port 211 ; the lower portion of the seed placement chamber 21 is provided with a discharge port 212 , and a discharge valve 213 is provided at the discharge port 212 .

[0031] The drying method comprises the following steps:

[0032] The discharge valve 213 is controlled to be closed, and the seeds to be dried are put into the feed port 211 until the seed placement chamber 21 is filled, and the hot air blower is controlled to blow hot air into the air inlet 11. The hot air gathers in the air inlet chamber 1. Under the action of air pressure, the hot air passes through the first mesh plate 22 and flows through the gaps between the seeds. Most of the hot air passes through the second mesh plate 23 and enters the condensation chamber 24. By contacting with the condensation tube 241, the moisture in the hot air is condensed and attached to the surface of the condensation tube 241. After condensation and drying, the hot air flows back to the air inlet chamber 1 through the reflux chamber 25 and the reflux pipe 26, and a small part of the hot air is directly discharged to the outside from the feed port 211; after the preset time, the hot air blower is turned off, the discharge valve 213 is opened, and the seeds are discharged from the discharge port 212 under the action of gravity.

[0033] In the above embodiment, the structure of the air inlet chamber 1 is designed, and the first circulation mechanism 2 and the second circulation mechanism 3 which are symmetrical to each other are respectively arranged on both sides of the air inlet chamber 1. In the first circulation mechanism 2, a vertical flat seed placement chamber 21 is surrounded by the first mesh plate 22 and the second mesh plate 23. When seeds are stored in the seed placement chamber 21, the lateral thickness of the seeds is small, so that the airflow in the air inlet chamber 1 can fully pass through the gaps between the seeds in the seed placement chamber 21, so that the seeds can be evenly contacted with the hot air, thereby being evenly dried. After the hot air passes through the seed placement chamber 21, it carries moisture. When most of the hot air passes through the condensation chamber 24, the moisture in the hot air condenses, so that the hot air is dried and refluxed to the air inlet chamber 1 through the reflux chamber 25 and the reflux duct 26, and is recycled again, thereby reducing the direct discharge of humid hot air to the outside, improving the utilization rate of hot air, and taking into account both drying uniformity and feeding and discharging efficiency.

[0035] As a preferred embodiment, the feed port 211 is in the shape of a long slot, and the feed port 211 is located between the two return pipes 26. The long slot-shaped feed port 211 further improves the seed feeding efficiency and also facilitates the discharge of part of the hot air from the feed port 211.
