Multiple-effect hot air seed drying device

Abstract

A multiple-effect hot air seed drying device comprises a machine body. A rack is arranged at the lower end of the machine body. Foot wheels are arranged at the bottom end of the rack. A drying box is arranged at the upper end of the rack. A dehumidification device is arranged at the left side of the top end of the drying box. A first hot air device is arranged in the middle of the top end of the drying box. A second hot air device is arranged at the middle end of the left side of the drying box. A controller is arranged at the upper end of the right side of the drying box. A third hot air device is arranged at the middle end of the right side of the drying box. A temperature sensor is arranged at the upper end of the left side in the drying box. A humidity sensor is arranged at the upper end of the right side in the drying box. Each of the left side and the right side of the bottom end in the drying box is provided with a circulating fan. A rotary screen is arranged at the middle end in the drying box. According to the multi-effect hot air seed drying device, the multi-effect hot air design is adopted, multi-side hot air drying is achieved, the seed drying efficiency is improved greatly, and the seed drying uniformity is improved greatly.

Description

technical field [0001] The invention relates to a seed drying device, in particular to a multi-effect hot air seed drying device. Background technique [0002] Generally, newly harvested seeds have a water content of 25%-45%. The seeds at this time are not suitable for storage, and the following hazards are likely to occur during storage: First, the respiration of high-moisture seeds is relatively strong, which will release a lot of heat, which is easy to cause the seeds to rot. Mildew; second, some seeds will produce alcohol due to hypoxic respiration, which will poison the seeds and reduce seed activity; third, when high-moisture seeds encounter low temperatures, they are prone to freezing, reducing seed activity, and even causing seed death; Fourth, high-moisture seeds tend to germinate when the temperature reaches a certain level, making the seeds unusable; fifth, high-moisture seeds are also prone to breeding insects and endangering seed safety. Therefore, before th...

Problems solved by technology

[0003] In the prior art, the commonly used seed drying method is a combination of ventilated drying and natural drying, which has the advantages of simplicity, energy saving, economical safety, Its disadvantage is that it is easy to be restricted by weather and site conditions, the labor intensity is relatively high, it requires more manpower, and the cost is high

Secondly, for the drying of large batches of seeds, drying or drying equipment is mostly used at present, while traditional drying equipment has more or less shortcomings in drying seeds, such as long drying cycle, uneven drying color, Energy consumption is high, drying quality cannot be guaranteed, and seed germination rate is affected, etc.
