Description

The present patent relates to agricultural processes and products in general, more specifically to a manufacturing process and end product of vacuum packed silage which, according to the general characteristics thereof, possesses as a basic principle to provide, by means of a proprietary and specific industrialized process, the manufacturing of an end product fully based on vacuum packed silages, that is, vacuum packing green forage to feed animals in general, with the purpose of providing a fully mechanized and optimized manufacturing process, and a silage of high nutritional and hygienic quality and, mainly, high durability, and having as a basis a packed silage of great durability, versatility and nutritious capacity. With a specific process for a better adaptation and safety for the users, practical handling and functionality, accessible cost and due to its general characteristics and dimensions, is easily adaptable to the most varied types of green forage or similar items, users and places in general, regardless of the characteristics thereof.

The patent in question is characterized in that it aggregates components and processes in a differentiated concept to meet the several requirements the nature of its use demands, that is, the attainment of a vacuum packed silage with high durability, that is, an extended application interval. Such concept provides a manufacturing process and an end product having great efficiency, functionality, strength, durability, versatility, accuracy and nutritional capacity due to its excellent technical qualities, thereby providing advantages and improvements to the transportation and storage of silages in general, the general characteristics of which differ from the other shapes and models of silages known in the current state of the art.

The present patent consists in the utilization of a modern, efficient, safe and functional manufacturing process and end product of vacuum packed silage formed by an assembly of properly incorporated agricultural, mechanical and physico-chemical solutions comprising a complete differentiated end product of vacuum packed silage of high durability and excellent finish qualities which, due to its proper characteristics, is achieved by means of a proper and specific manufacturing process incorporating an assembly of successive and properly integrated operations formed by a harvesting and chopping phase of the green forage in the fields as a preparation thereof, a packing and weighting phase, a pressing phase to arrange the green forage, a bag vacuum phase to remove air from the bag and a storage phase to allow the green forage to ferment, so as to provide the formation of a unique, complete and safe assembly, whose shapes and internal and external arrangements provide the vacuum packing of several types of green forage, with the specific purpose of providing the application of silages irrespective of the storage and transportation conditions that may be found.

Cattle, be that dairy cattle or beef cattle, need high quality food throughout the year. Weather conditions in most regions, however, does not allow for green pastures during every month of the year. Result: in the rainy season, pastures abound; in the dry season, they are in shortage; in wintertime, they are completely destroyed by the snow and frost; in many regions, the cattle starve to death. And that in normal conditions, when no droughts, rainfalls or extended winters occur or even during the attack of plagues or diseases, which worsens the situation even more. Throughout the centuries, though, countries with advanced agriculture have learned how to overcome such problems, mainly due to the development of methods of preserving green material for cattle feed during pasture shortage months, being the ensilage process the most important one among those methods, an extremely simple, economical, and practical way—therefore, within the range of any cattle breeder—of storing forage for a long period of time, provided special conditions are kept, and preserving almost of all of the properties of its nutrients and comprising the entire silage production process, which includes forage plantation, and its subsequent harvesting, fragmentation, transport, silo loading, compacting, sealing and use of the ready product.

Silage is the product of the fermentation process of green forage in special conditions, for a certain period of time, provided it is completely protected from air, being this factor—absence of air—the most important requirement to achieve proper results in the production of silage and the durability thereof. Silage preserves the properties of forage for several months in the absence of oxygen, during which it is used as food for the cattle, mainly dairy cows. This way, silage is a way of making the cost of production cheaper, thus saving in rations and other types of cattle food. The practice of ensilage has been shown to be highly feasible, for besides providing plenty of food for the cattle throughout the year, irrespective of the weather conditions, the cattle farmer yields greater productivity in milk and beef when supplying animals with silage associated with other foods.

During the ensilage process, forage remains alive after harvesting, that is, its cells use oxygen and feed themselves from the reserves found in the plant tissues; the plants, along with the soil and the atmosphere, contain several microorganisms (bacteria, fungi, etc.) that can develop in favorable conditions, like moisture, proper temperature and the absence of air. After harvesting, chopping and loading forage in the silo, bacterial action starts and, as the silo must be loaded by eliminating as much oxygen as possible from the mass and fully excluding air and water seepage, the residual oxygen is consumed by the plant cells that help start the bacteria anaerobic (free of oxygen) reaction, that is, the fermentation of forage, a process which is concluded after a thirty-day cycle, upon reaching stability. At such specific conditions, the silage will keep for an indefinite period of time providing it does not enter in contact with air and water, thus keeping its properties, taste and smell favored by the cattle; otherwise, it must be quickly consumed.

Thus, the main inconvenient of the shapes and models of silages known in the current state of the art is the storage and transportation thereof, due mainly to the high degree of spoilage and extremely low durability; current processes allow silages to be marketed for a maximum period of twenty four hours in the presence of air; beyond that, they spoil.

In view of those inconveniences, the general concept of the manufacturing process and end product of vacuum packed silage is based on packing the forage in a bag immediately after its harvesting, so as to undergo the anaerobic fermentation process and, consequently, originate the silage end product, that is to say, the fermentation of vacuum packed green forage occurs directly inside the bag over a 20 to 30 day period. After that time, silage is ready to be directly consumed by the animals, and provided it is kept inside the bag, it can be stored for the same period of time as a conventional silage, that is, more than one year; as long as the bag is sealed, there is no oxygen contact and, therefore, no product spoilage. Thus, marketing of silage, currently restricted due to its sudden deterioration, is hugely facilitated, because packed silage can be transported and stored for longer periods and in several different quantities, being suitable for animal consumption for a long period of time, to be used in the proper time and amount required.
