    PROCEDURE FOR MANAGEMENT OF VEGETABLE REMAINS OF GREENHOUSE WITHOUT CHEMICAL AGENTS AND PLANT TO CARRY OUT
    D E S C R I P C I Ó N
    OBJECT OF THE INVENTION
    The invention, as stated in the present specification, refers to a procedure for the management of greenhouse plant residues without chemical agents and plant to carry it out, which represent a remarkable novelty.
    More specifically, the object of the invention focuses on a process for managing plant residues from the greenhouse, without the intervention of chemical agents, for its transformation into pelletized feed with structural and nutritional characteristics suitable for its intake by ruminants. In addition, a second aspect of the invention refers to the management plant for carrying out said procedure.
    FIELD OF APPLICATION OF THE INVENTION
    The field of application of the present invention falls within the sector of the industry dedicated to waste management and its use, focusing particularly on the field of agricultural plant remains.
    BACKGROUND OF THE INVENTION
    Greenhouse vegetable waste is a type of fignocellulosic biomass that can be suitable for use in different thermochemical processes of heat and electricity generation. However, these thermal processes develop at elevated temperature and involve irreversible chemical relationships and heat transfer phenomena.
    The formulas of commercial innovation in the fruit and vegetable sector, specifically the Almeria, have not allowed to reverse the real relations of exchange between agricultural inputs and the final product. Only the increase in productivity has been able to compensate for the increase in prices, in many cases hedonic prices, of the agricultural inputs of intensive agriculture under plastic.

    Technology has influenced two ways in increasing profitability. It has contributed to improve production conditions, and improve marketing conditions:
    • Advance of the collection date.
    • Adaptation of products to the demands and needs of consumers (size, quality, safety, taste ...)
    The process of incorporation of technology and application of novel agronomic techniques, which identifies the Almeria fruit and vegetable production model, is circumscribed more clearly to a process of technical adaptation than to a process of technological innovation. We are talking about an agronomic model based on a dynamic trial and error innovation, framed in a market horizon that has been incorporating parallel information on fallible technical incorporations and low travel, and applications that incorporated value.
    The technologies introduced and the applied techniques of agronomic management have been happening according to the model and its needs. Among the main technical applications, sanding, plastic covers (padding and greenhouses), drip irrigation systems, the use of hybrid seeds, improvements in the greenhouse structure, soilless crops and hydroponic crops, should be highlighted. farm climate control ...
    This small introduction leads us to the initiative after several years of studies and tests for the reuse and use of part of the amount of greenhouse plant waste.
    The large concentration of greenhouses in the Mediterranean area has allowed a great economic and social development as we indicated earlier. This has also led to the generation of a large amount of waste, organic and inorganic. Almería (Spain) has an area of greenhouses of approximately 26,000 ha, being the largest concentration of greenhouses in the world, with a production of almost 3 million tons. In addition to this commercial production, the production of organic waste in fresh weight annually reaches a value of 1.9 million tons.
    An effort has been made in recent years, both by private companies and
    5

    public bodies, to reduce, reuse or reuse different types of waste. The organic fraction is the one that is mostly present in the waste generated and therefore where the actions are mainly focused. Thus systems have been developed for the production of compost, biogas etc ...
    In the Spanish Mediterranean area there are about 38,000 ha of greenhouses, of which 27,000 ha are located in Almería, which generate a large volume of plant waste. The handling and treatment of such waste is complex due to heterogeneity, since they include the polyethylene threads used as tutors, high dispersion and generation of waste throughout the year. The reuse of greenhouse plant waste as a source of heat and feed material would not only eliminate the environmental problem, but also create jobs both direct and indirect.
    The treatment of greenhouse vegetable waste in the province of Almeria is a problem due to its quantity and heterogeneity. In addition, its withdrawal and treatment is an important expense for the farmer. The reuse of waste as a source of heat would eliminate the environmental problem and raise the nighttime temperature of the greenhouse in cold periods, which is usually below the optimum.
    The objective of the present invention is, therefore, to develop a method and technology to separate in the same production line the contaminating and aggressive elements of the greenhouse plant residues for any type of subsequent process such as raffia, metal clips etc. and make feed pellets suitable for ruminants.
    On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of no other procedure for the management of plant debris or plant to carry it out that presents technical characteristics is unknown, Structural and constitutive same or similar to those presented here that is recommended and as claimed.
    EXPLANATION OF THE INVENTION
    The procedure for the management of greenhouse plant residues without chemical agents and plant to carry it out that the invention proposes is thus configured as a remarkable novelty within its field of application, since, according to its

    implementation and in a restrictive manner, the aforementioned objectives are satisfactorily achieved, the characterizing details making it possible conveniently included in the final claims that accompany the present description.
    Specifically, what the invention proposes, as noted above, is a procedure and a plant for the management of plant debris from the greenhouse, without the intervention of chemical agents that allow its transformation into pelletized feed with adequate structural and nutritional characteristics for its intake by ruminants.
    The nutritional values made in by-products obtained comparable to the current food products included in the diet of this category of animals. Therefore, said process and said plant represent an advantageous way to reuse tons of raw material that now poses a problem for farmers, particularly in the Almeriense area of the Levant, making said material a product of great added value for the animal feed industry .
    To do this, and specifically, said procedure and the plant to carry it out include the following:
    For the procedure, the following stages are contemplated:
    - shredded material by blades;
    - sorting and manual separation of the non-vegetal parts mixed with the material, such as raffia and other elements, as well as the removal by magnets of any metallic waste that may contain once classified;
    - drying of the material in a rotary kiln;
    - milling of the material once dried;
    - screening in thromel to dose bulk material
    - transformation of the chopped and treated material into pellets, according to customer requests, by pelletizing machine.
    And, to carry out said procedure, the plant, which is configured as a line for crushing the greenhouse plant remains, essentially comprises the following
