FILTRO DE ABSORCION DE ETILENO DESCRIPCIONETHYLENE ABSORPTION FILTER DESCRIPTION
Campo de la inventionField of the invention
La presente invention se refiere a la composition de un filtro de absorcion de etileno y microorganismos que se encuentran en la atmosfera donde se conserva fruta, verdura y flores, asl como a su proceso de fabrication y sus posibles usos solo o acoplado a maquinas que permiten el paso del aire.The present invention relates to the composition of an absorption filter of ethylene and microorganisms that are found in the atmosphere where fruit, vegetables and flowers are preserved, as well as its manufacturing process and its possible uses alone or coupled to machines that allow the passage of air
Antecedentes de la invencionBackground of the invention
Es bien conocido en el estado de la tecnica que los productos vegetales, por ejemplo, frutas, hortalizas o flores, se transportan de manera refrigerada en camiones, bodegas, barcos, etc.... La atmosfera en la que se encuentran estos productos hace que se produzca etileno en cantidades importantes, asl como otros productos gaseosos, humedad o incluso microorganismos que no son deseables para el propio producto.It is well known in the state of the art that plant products, for example, fruits, vegetables or flowers, are transported refrigerated in trucks, warehouses, boats, etc ... The atmosphere in which these products are located makes that ethylene is produced in significant quantities, as well as other gaseous products, moisture or even microorganisms that are not desirable for the product itself.
El etileno es el principal agente inductor de la maduracion de frutas y hortalizas y puede causar la maduracion prematura de algunos productos o arruinar otros. En el caso de flores se acelera el marchitamiento de las mismas. Una concentration elevada de este gas produce un envejecimiento prematuro del producto, que se ablanda y pierde su calidad. Nunca se deben transportar o almacenar frutas y verduras que produzcan etileno con productos que son sensibles al mismo.Ethylene is the main inducing agent of fruit and vegetable ripening and can cause premature ripening of some products or ruin others. In the case of flowers the wilting of them is accelerated. A high concentration of this gas causes premature aging of the product, which softens and loses its quality. Fruits and vegetables that produce ethylene with products that are sensitive to it should never be transported or stored.
Hasta la fecha se han desarrollado filtros que intentan evitar este problema. En particular, el documento ES2401218B1 describe un filtro de absorcion de etileno para espacios refrigerados formado por un granulado interior, un cuerpo tubular orificado y una funda de malla. El sustrato poroso que se utiliza en la formation del granulado puede estar formado de los siguientes materiales: tierra de diatomeas, zeolitas, tamiz molecular, celita, perlita, aluminas, mica, aluminato de magnesio, aluminosilicato, silicato de magnesio, carbon activado, arcillas absorbentes, kaolin, silica gel y sus mezclas; con una impregnation que suele incorporar un permanganato.To date, filters have been developed that try to avoid this problem. In particular, document ES2401218B1 describes an ethylene absorption filter for refrigerated spaces formed by an inner granulate, an orified tubular body and a mesh sheath. The porous substrate that is used in the formation of the granulate can be formed from the following materials: diatomaceous earth, zeolites, molecular sieve, celite, perlite, aluminas, mica, magnesium aluminate, aluminosilicate, magnesium silicate, activated carbon, clays absorbents, kaolin, silica gel and mixtures thereof; with an impregnation that usually incorporates a permanganate.

Los presentes inventores han desarrollado un filtro de etileno con una composition que incorpora sllice pirogenica en lugar de silica gel habitual. La sllice pirogenica consiste en gotas microscopicas de sllice amorfa que se fusionan en partlculas secundarias tridimensionales ramificadas, y posteriormente se aglomeran en partlculas terciarias. El polvo resultante tiene una densidad baja y un area superficial elevada. Con la incorporation de este componente en la formulation del filtro tambien se consigue que no sea necesaria la coccion para la elaboration del filtro como se describe en la fabrication de filtros del estado de la tecnica.The present inventors have developed an ethylene filter with a composition that incorporates pyrogenic silica instead of the usual silica gel. Pyrogenic silica consists of microscopic drops of amorphous silica that merge into branched three-dimensional secondary particles, and subsequently agglomerate into tertiary particles. The resulting powder has a low density and a high surface area. With the incorporation of this component in the formulation of the filter it is also achieved that cooking is not necessary for the preparation of the filter as described in the manufacture of filters of the state of the art.

Una vez se consigue una mezcla homogenea se anaden 312 g de carbon activo con un mdice de yodo de 1000 mg/g y una densidad aparente de 520-540 kg/m3. A continuacion, despues de volver a tener una mezcla homogenea se anaden 312 g de sflice pirogenica y se vuelve a mezclar. Finalmente a la mezcla homogenea obtenida se anaden 1,25 kg de agua y se mezcla bien hasta obtener el producto final. Dicho producto final presenta una granulometria caracteristica con un grano de 0,595-1,51 mm de diametro (frente al grano de como mmimo 3-5 mm de diametro de los productos actuales). Cabe indicar que todo el proceso se realiza a temperatura ambiente evitando en todo momento la aparicion de grumos en las mezclas.In order to make the filter of the invention, 10 kg of sepiolite are mixed with 0.625 kg of potassium permanganate. Once a homogeneous mixture is achieved, 312 g of active carbon with an iodine content of 1000 mg / g and an apparent density of 520-540 kg / m3 are added. Then, after having a homogenous mixture again, 312 g of pyrogenic silica are added and mixed again. Finally, 1.25 kg of water are added to the homogeneous mixture obtained and mixed well until the final product is obtained. Said final product has a characteristic granulometry with a grain of 0.595-1.51 mm in diameter (compared to the grain of at least 3-5 mm in diameter of current products). It should be noted that the whole process is carried out at room temperature avoiding at all times the appearance of lumps in the mixtures.
