Description
Technical Field
The utility model relates to the technical field of seed drying treatment, in particular to a novel energy-saving plant seed drying system.
Background
In general, plant seeds are dried by adopting a hot air drying method, and the method uses a forced air drying box, so that the equipment is simple, the operation is easy, the drying speed is high, but potential damage is easily caused by simply heating the seeds, and the water content of the seeds is difficult to reduce to the use requirement in wet seasons. In addition, the water content of the germplasm resources or seeds of crops, woods, medicinal plants, ornamental plants and the like newly collected from the field is different, and if the crops, such as beans, are dried by adopting a drying oven at 38-40 ℃, the surfaces of the seeds are often broken and damaged. Therefore, the drying technique cannot meet the requirements of germplasm libraries.
After the hot air drying method is based on the above, improvements are made, namely, a dehumidifying device and a refrigerating device are added. The drying system is formed by connecting three parts of a rotary dehumidifier, a set of refrigeration equipment and a drying box. The rotary dehumidifier is responsible for reducing the humidity in the box body and is generally set below 7% RH. The drying box is an air-blast drying box, a fan is arranged at the bottom of the box, the temperature range can be controlled to be 0-40 ℃, and the air inlet temperature of the box body is controlled to be 17+/-2 ℃ by a refrigerating system. Because each box body can independently control the temperature in the box body, the temperature of the seed drying box is constant at 35 ℃ or 38 ℃ after the seed drying box is opened, and the humidity in the box body is controlled below 12%, so that the seeds are dried and dehydrated.
However, the following technical problems still exist in the improved technical scheme: 1. when the ambient temperature and humidity are lower than the set temperature and humidity, the drying system is not started, so that the temperature and humidity in the box body are inconsistent with the set temperature. 2. When the temperature and humidity reach the set temperature and humidity, a shutdown phenomenon can occur, so that the working efficiency is reduced. 3. The temperature difference is large, and after the temperature and the humidity are set, the temperature can fluctuate within +/-2 ℃, so that the temperature difference in the box body is 5 ℃. 4. When the indoor and outdoor temperature difference is large, the refrigerating unit is frequently started and the output refrigerating capacity is overlarge, so that the power consumption is increased. 5. Because the refrigeration and dehumidification systems are required to be carried out simultaneously, the temperature and the humidity can be independently controlled to start and stop, one index of the two indexes does not meet the requirement, the whole system can continuously work, the other index is continuously reduced, and the seed drying effect is influenced. 6. The long-term operation of the dehumidifier heater leads to an increase in power consumption.
