A cavity for storing seeds is formed between plates II;

exhaust pipe, which is arranged on the upper end of the drying box; and

The condenser is connected to the nozzles at the upper ends of the other exhaust pipes, and is used to condense the water vapor discharged from the exhaust pipe into water.

The above-mentioned condenser includes a heat exchange box sealed all around, heat exchange tubes arranged in the heat exchange box, a water tank and an evaporation pool with a closed upper end opening around it, and the water tank is connected to the inlet of the heat exchange tube through a pump I through a water inlet pipe. , the outlet of the heat exchange tube is connected to the evaporation pool through the return pipe, the exhaust pipe is connected to the heat exchange box, the bottom of the heat exchange box is connected to the evaporation pool through the drain pipe, and the evaporation pool is passed through the water supply pipe Pump II is connected to the water tank.

In order to improve the circulation efficiency of the hot air, it also includes rotating the fan blade installed in the drying box, and the fan blade is driven to rotate by the fan blade motor.

In order to speed up the drying efficiency, sponges are fixed on the outer surfaces of the sieve plate I and the sieve plate II respectively.

The beneficial effects of the utility model are: after the seeds are loaded into the cavity, the hatch door is closed, the electric heater heats up, the temperature in the entire drying box rises, the motor rotates to rotate the screen plate I and the screen plate II, and the seeds are dried during the drying process. The volatilized water is discharged through the sieve plate I and the sieve plate II to become water vapor, and the high-temperature water vapor enters the condenser through the exhaust pipe to condense into water, thereby improving the efficiency of seed drying, improving the uniformity and degree of dryness.

detailed description

Below in conjunction with accompanying drawing 1, accompanying drawing 2 the utility model is described further.

A seed dryer, comprising: a drying box 1, the surroundings of which are airtight, an opening 2 is provided at the front end, and a hatch is provided at the opening 2;

The electric heater 3 is arranged in the drying box 1; the screen plate I 17 and the screen plate II 18 are interlocked, and the two ends of the screen plate I 17 and the screen plate II 18 are respectively rotated and installed in the drying box 1 through the rotating shaft 16 Inside, one of the rotating shafts is connected to the motor 20, and a cavity 19 for storing seeds is formed between the screen plate I 17 and the screen plate II 18; the exhaust pipe 5 is arranged at the upper end of the drying box 1; and the condenser , the other exhaust pipes 5 upper ends are connected to each other, and are used to condense the water vapor discharged from the exhaust pipe 5 into water. After the seeds are loaded into the cavity 19, the hatch is closed, the electric heater 3 heats, the temperature in the whole drying box 1 rises, the motor 20 rotates to rotate the screen plate I 17 and the screen plate II 18, and the volatilized during the seed drying process The water is discharged through the screen plate I 17 and the screen plate II 18 to become water vapor, and the high-temperature water vapor enters the condenser through the exhaust pipe 5 to condense into water, thereby improving the efficiency of seed drying and improving the uniformity of seed drying and dryness.

The condenser can have the following structure, which includes a heat exchange box 6 sealed all around, a heat exchange tube 7 arranged in the heat exchange box 6, a water tank 12 and an evaporation pool 13 with a closed upper end opening around it, and the water tank 12 passes through the water inlet pipe 8 The pump I 9 is connected to the inlet of the heat exchange pipe 7, the outlet of the heat exchange pipe 7 is connected to the evaporation pool 13 through the return pipe 10, the exhaust pipe 5 is connected to the heat exchange box 6, and the bottom of the heat exchange box 6 is passed through the drain pipe 11 Connected to the evaporation pool 13, the evaporation pool 13 is connected to the water tank 12 through the pump II 15 through the water supply pipe 14.
