Natural Drying The ground drying method will dry the harvested pasture either in situ or in a relatively dry place. The harvested pasture is usually dried for 4 hours to 6 hours. After the moisture is reduced to about 40%, the grass is used to dry the grass and the moisture is reduced to about 35%. Then the grass is integrated into the haystack with a grass collector. And keep the straw loosely ventilated until the grass is completely dry. Straw Drying Method In a relatively humid area or in a season where there is a lot of rain, hay can be prepared on a specially made grass stand. Hay racks include wooden stands, tripods, curtain sheds, wire racks, and activity racks. Drying on the shelf can greatly improve the drying speed of pasture and ensure the quality of hay. When drying on the shelf, the grass should be placed on the grass rack from top to bottom, the thickness should be less than 70 cm, and it should be kept fluffy and with a certain degree of inclination in order to facilitate the lighting and drainage. Fermentation Drying The fermentation drying method is to dry the harvested pastures first, so that when the moisture content is reduced to about 50%, the haystacks will be compacted layer by layer to a height of 3m to 5m, and the surface of the earthworms can be soiled or soiled. The film is covered so that the temperature of the grasshopper reaches 60° C.-70° C. in two or three days, and then the grass is dried in a sunny day and the grass is dried. When encountering continuous rainy days, it can be allowed to ferment for a longer period of time under the premise that the temperature does not rise excessively, and the dried hay has a greater loss of nutrients. Artificial Drying Drying method uses a fan, blower, and blower to unheat dry the haystack or haystack. Normal-temperature blast drying is suitable for use in pasture harvest days where the relative humidity is less than 75% and the temperature is higher than 15°C. The air used for blowing in a particularly humid place can be properly heated to increase the drying speed. The high-temperature rapid drying method uses a dryer to quickly evaporate the water of pasture. After a few minutes or seconds after the high-moisture pasture has passed through the dryer, the water content drops to 5%-10%. Modulation of hay by this method has little effect on the nutritional value and digestibility of herbage, but it requires higher input and the cost increases significantly. The physical drying method of fracturing grass stem drying method The length of the drying time of the grass depends mainly on the time it takes for the stem to dry. The drying speed of the leaves is much faster than the stem and the time required is short. In order to keep the dry time of pasture stems and leaves consistent and reduce the loss of the leaves during drying, the stem stalk crusher is often used to crush the stalks and eliminate the hindrance to moisture evaporation from the stratum corneum and vascular bundles. The evaporation rate of moisture in the stalk maximizes the drying speed of the stem and the drying speed of the blade. Fracturing stalks to dry pastures takes about 1/2 to 1/3 less time than fracturing stalks.
