Substantiation of the Parameters of a Slit Sprayer for Applying Biological Products when Harvesting Bulky Feeds with High Humidity

The main method of harvesting hay is its pressing, in which a mandatory requirement is to ensure constant conditioned humidity of the material. Compliance with such material parameters in the field is very difficult. Therefore, in order to achieve maximum efficiency when harvesting bulky, it is necessary to use various bioconservants and their uniform distribution over the surface of the selected roll. One of the conditions for the operation of the distribution system is the use of high pressure to crush a drop of a solution of a biological product, which negatively affects the effectiveness of the preservative. In the course of the work, the performance of the sprayer was studied depending on the pressure in the pneumatic system of the spraying device and the diameter of the feeding tube.
