dc.description.abstract | Hay is a bulky part of the meal that is most often used in the winter period of the
year in all types of ruminants, while the role of hay in the meal of high-milk cows is invaluable.
The most common way to produce hay is to dry the cut grass on the surface of the land in the field,
using the energy of the sun. In the process of hay production, there is a reduction of nutrients in
relation to the green mass, where the achieved yield and quality of hay largely depends on the
technological operations that are performed during storage. In the baling process, the dried mass
is exposed to the mechanical treatment of the working elements of the press, as a result of which
the leaf mass decreases. Loss of leaf mass, which contains a large amount of nutrients, can greatly
affect the achieved yield and quality of the obtained hay. One of the possibilities to reduce losses is
the application of "DewPoint" technology, which involves the use of water vapor in the baling
process. The steam produced by the device is injected into the mass-hay after lifting by the pickup
device and further until the mass enters the pressing chamber. Mass treatment is achieved by
injecting steam through a series of nozzles located inside the press. Water vapor is an extremely
efficient medium for the controlled hydration of hay during the baling process, where
approximately 450 l of water vapor can be produced from 1 l of water. By applying this
technology, water consumption is 5-7 l per 1 t of hay, producing 2250-3150 l of water vapor. This
amount of steam enables efficient treatment of individual plants (tree, leaf) in a mass of 1t to the
desired humidity level. | sr |
