There are many ways to dry the pasture. The natural drying method, the artificial drying method (grass dryer) and the physicochemical drying method are often seen. Today we are talking about the manual drying method using the pasture dryer. What is the specific?
Several methods of artificial drying:
1. Drying of the air: using a fan, a blower to carry out the method of not heating and drying the haystack or grasshopper. The room temperature blast drying is suitable for the day and night relative humidity of the forage harvesting period below 75% and the temperature is higher than use at 15 °C. The air used for blowing in particularly humid places can be heated appropriately to increase the speed of drying.
2. High temperature rapid drying: the dryer will quickly evaporate the moisture of the grass, the grass with high water content in the dryer after a few minutes or a few seconds, the water will drop to 5% -10%. The preparation of hay has little effect on the nutritional value and digestibility of pasture. But the need for higher inputs, the cost of hay has increased dramatically.
Therefore, the method of drying the forage must be decided according to the situation.
