There are many methods for drying pasture, which are divided into natural drying and artificial drying. The natural drying cycle is long, the floor space is large, and the manpower input is large. The artificial drying method is mainly fast and efficient, and the nutrient loss is small. The pasture dryer is a mechanized operation of hot air and rapid drying, which reflects the characteristics of modern industry.
The dry nature of the pasture can be dried on the ground, dry under the straw and dried by fermentation, but the cycle is long, and the nutrition of the forage has a greater degree of damage. At the same time, the economic cost of pasture is increased at a time when industrialization is getting higher and higher.
There are two methods for manual drying of pasture, such as blast drying method and high temperature drying. The method of blast drying requires that the humidity is lower than 75% and the temperature is higher than 15 degrees, which is usually suitable for the hay harvest period, while the air humidity is higher, such as in the south, the air needs to be warmed, and the dry quality of the pasture is higher than that in the wild.
The high temperature drying of the pasture does not require humidity or temperature, but the hot air is heated by the hot air oven, and the tumble dryer is used as a carrier for rapid drying, and has a lower impact on the nutrient content and digestibility of the pasture.For example, the early harvested alfalfa uses a pasture dryer to produce hay, the crude protein content is 20%, and the cellulose is below 24%, the method of drying the forage grass makes the hay humin content about 90% to 95% compared with the grass, and the damage is small. The rate of forage drying is to directly reach about 15% of the grass with a water content of about 80% per unit weight in a few seconds.
Therefore, in contrast, more pasture operators choose grass dryers for fast and efficient production of hay feed. Zhengzhou Dingli is a professional manufacturer of forage dryers, providing free installation and technical guidance to ensure high quality production on time.
