1. Use a tube-bundle dryer to dry rapeseeds, which have higher moisture content. In order to ensure drying efficiency and drying effect, the temperature of the hot air should be controlled at about 100-200 degrees. If drying forage seeds, the temperature of the hot air should be controlled at 40-60 degrees.
2. For grain seeds, it is best to control the temperature of the hot air at about 40-60 degrees. The germination rate of grain seeds dried at this temperature is very high. If you want to dry wheat, the temperature of the hot air cannot be lower than 40 degrees or higher than 100 degrees. If the temperature exceeds or falls below this range, the drying effect and efficiency will be affected. The material is corn, and the temperature should be controlled between 80-140 degrees depending on the moisture content.
