Description
Procedimiento de obtención de un fertilizante en forma de gel. Procedure for obtaining a gel-shaped fertilizer.
La presente invención se refiere a un procedimiento de obtención de un fertilizante en forma de gel, previsto preferente y fundamentalmente para utilizarse en atomizadores, es decir en máquinas arrastradas por un tractor o autopropulsadas, con un tanque de caldo o producto de muy diversos volúmenes, y en donde los atomizadores, como es sabido, realizan una pulverización de la disolución diluida del fertilizante sobre las hojas de los árboles. The present invention relates to a method of obtaining a fertilizer in the form of a gel, preferably provided and fundamentally for use in atomizers, that is to say in machines dragged by a tractor or self-propelled, with a broth tank or product of very different volumes, and where the atomizers, as is known, spray the diluted fertilizer solution on the leaves of the trees.
El objeto de la invención es conseguir un producto o fertilizante de apariencia líquida pero con una concentración de fertilizante muy superior a la que químicamente es admisible en una disolución. The object of the invention is to obtain a product or fertilizer of liquid appearance but with a fertilizer concentration much higher than that which is chemically admissible in a solution.
Como es sabido, en el mundo de los fertilizantes existen muchas clases de estos productos, en lo que se refiere a composiciones de los mismos, mientras que en lo que se refiere al aspecto o forma de presentación, se distinguen dos tipos muy concretos que corresponden a: As is known, in the world of fertilizers there are many kinds of these products, in terms of their compositions, while in terms of appearance or form of presentation, there are two very specific types that correspond to:
- --
- abonos/fertilizantes sólidos, que se presentan en forma de sal soluble en agua y que pueden presentarse de muchas formas, como puede ser sal molida, polvo, granulado, perlado, etc. solid fertilizers / fertilizers, which are in the form of a water-soluble salt and can be presented in many forms, such as ground salt, powder, granules, pearls, etc.
- --
- abonos/fertilizantes líquidos, que son disoluciones mas o menos concentradas de las sales que contienen los elementos nutritivos. liquid fertilizers / fertilizers, which are more or less concentrated solutions of the salts that contain the nutritional elements.
Conseguir un fertilizante de apariencia líquida con una concentración de fertilizante muy superior a la que químicamente es admisible en una disolución, teóricamente puede llevarse a cabo mediante una disolución sobresaturada de fertilizante, conteniendo sal suspendida sin poderse disolver, ya que la disolución ya se encuentra saturada. Achieving a liquid-looking fertilizer with a fertilizer concentration much higher than that which is chemically admissible in a solution, theoretically can be carried out by means of a supersaturated fertilizer solution, containing suspended salt without being able to dissolve, since the solution is already saturated .
No obstante, dado que la sal no se encuentra disuelta, ésta se va al fondo del recipiente, quedando un sobrenadante líquido y una masa cristalina en el resto del recipiente. Además, si se tiene en cuenta que la fase sólida depositada en el fondo corre el riesgo de recristalizarse con cambios de temperatura (bajada de temperatura), se puede formar un bloque imposible de liberar por mucha agitaci�n que se pretenda dar al recipiente en cuestión. However, since the salt is not dissolved, it goes to the bottom of the container, leaving a liquid supernatant and a crystalline mass in the rest of the container. In addition, if it is taken into account that the solid phase deposited in the bottom runs the risk of recrystallizing with changes in temperature (temperature drop), an impossible block can be formed due to the high agitation that is intended to be given to the container in question.
Por consiguiente, aunque teóricamente podría conseguirse un fertilizante con apariencia líquida con una concentración muy superior a la que químicamente es admisible en una disolución, sin embargo en la práctica resulta inviable por lo anteriormente expuesto. Therefore, although theoretically a fertilizer with a liquid appearance could be achieved with a concentration much higher than that which is chemically admissible in a solution, however in practice it is unfeasible because of the above.
La invención se refiere a un procedimiento de obtención de un fertilizante que puede comercializarse en forma de gel, para lo que al fertilizante se le incorpora un agente espesante o viscosizante para incrementar la resistencia de cualquier partícula a atravesar el fluido, con lo que la fase líquida tomar� un aspecto de gel y las partículas contenidas en él no pueden caer al fondo dado que la resistencia que presenta el gel a deformarse es superior al peso de las partículas y por lo tanto éstas quedan suspendidas y no caen al fondo. The invention relates to a process for obtaining a fertilizer that can be marketed in the form of a gel, for which the fertilizer is incorporated with a thickening or viscosifying agent to increase the resistance of any particle to pass through the fluid, whereby the phase liquid will take on a gel appearance and the particles contained in it cannot fall to the bottom since the resistance of the gel to deform is greater than the weight of the particles and therefore they are suspended and do not fall to the bottom.
El gel, como es lógico, es bastante fluido y puede manejarse adecuadamente en cualquier tipo de recipiente, siendo su aspecto similar a un gel de baño, pero apreciándose al tacto las partículas sólidas disolver, de manera tal que éstas se disuelven cuando el producto se mezcla con agua clara, y el gel se dispersa, con lo que las partículas fertilizantes quedan libres y son disueltas rápidamente por el agua. The gel, of course, is quite fluid and can be handled properly in any type of container, its appearance being similar to a bath gel, but the solid particles dissolve to the touch, so that they dissolve when the product dissolves. mix with clear water, and the gel disperses, so that the fertilizer particles are free and quickly dissolved by water.
De esta manera se puede conseguir fertilizante en forma líquida pero viscosa, manejable en envases de líquidos con concentraciones similares a los sólidos. In this way, fertilizer can be obtained in a liquid but viscous form, manageable in liquid containers with concentrations similar to solids.
Mas concretamente, para la obtención de fertilizante en forma de gel, se llevan a cabo las siguientes fases operativas: More specifically, to obtain a gel-shaped fertilizer, the following operational phases are carried out:
- --
- Introducci�n en un tanque con agitaci�n continua, de una cantidad de agua apropiada para la elaboración de un gel. -Aplicación sobre el mismo tanque de la cantidad de sal o sales necesarias que se deseen para conseguir el fertilizante definitivo, manteniéndose la agitaci�n continua. Introduction in a tank with continuous agitation of an amount of water appropriate for the preparation of a gel. -Application on the same tank of the amount of salt or necessary salts that are desired to achieve the final fertilizer, maintaining continuous agitation.
- --
- A continuación se añade sobre el mismo bidón y manteniendo la agitaci�n continua, una cantidad de espesante que permita la texturizaci�n del volumen del fertilizante que se pretende obtener, produci�ndose una rápida dispersi�n y posterior inicio de la texturizaci�n del producto. Subsequently, a continuous amount of thickener is added on the same drum and maintaining continuous agitation, which allows the texturing of the volume of the fertilizer to be obtained, producing a rapid dispersion and subsequent start of the texturing. of the product.
- --
- Mantenimiento de la agitaci�n durante, al menos, dos o tres horas seguidas, de manera que al término de dicho intervalo de tiempo se detiene la agitaci�n. Maintaining the agitation for at least two or three hours in a row, so that at the end of said time interval the agitation stops.
- --
- Aplicaci�n de agitaciones durante quince minutos por cada hora, durante un tiempo de varios días, obteniéndose al final un producto fertilizante en forma de gel y apto para su comercialización. Stirring application for fifteen minutes per hour, for a period of several days, obtaining in the end a fertilizer product in the form of a gel and suitable for commercialization.
El espesante estar� preferente y fundamentalmente materializado a base de goma xantana mezclada y diluida en alcohol isopropil�co en el que se diluye fácilmente, de manera que el alcohol se dispersa perfectamente en cualquier disolución que se est� agitando, aunque sea con suavidad, incorporándose la goma xantana a la disolución casi de forma inmediata sin formar grumos. The thickener will be preferably and essentially materialized based on xanthan gum mixed and diluted in isopropyl alcohol in which it is easily diluted, so that the alcohol disperses perfectly in any solution that is being stirred, even if gently, Xanthan gum being incorporated into the solution almost immediately without lumping.
De acuerdo con las fases del procedimiento referidas, en un plazo de 24 horas, el 80-90% de la goma xantana se ha hidratado con el agua de la disolución, resultando una textura prácticamente definitiva, de manera que en pocos días y según la temperatura ambiente, el producto es apto para envasarse y comercializarse. In accordance with the referred phases of the procedure, within a period of 24 hours, 80-90% of the xanthan gum has been hydrated with the water of the solution, resulting in a virtually definitive texture, so that in a few days and according to the room temperature, the product is suitable for packaging and marketing.
El fertilizante obtenido, como ya se ha expuesto, se utilizar� preferentemente en atomizadores que pulverizan la disolución diluida del fertilizante sobre las hojas de los árboles, de manera que al ser un formato gelificado del producto, el agua del mismo aumenta un poco su viscosidad, resultando casi imperceptible a simple vista, pero lo suficiente para que se adhiera mejor a las hojas y evitar el goteo. Es decir mediante el fertilizante obtenido se rentabiliza la aplicación, dado que los árboles tienen a su disposición mas cantidad de producto para ser absorbido por vía foliar. The fertilizer obtained, as already explained, will preferably be used in atomizers that spray the diluted solution of the fertilizer on the leaves of the trees, so that being a gelled format of the product, its water slightly increases its viscosity , being almost imperceptible to the naked eye, but enough to adhere better to the leaves and prevent dripping. That is to say, through the fertilizer obtained, the application is profitable, since the trees have at their disposal more quantity of product to be absorbed by foliar route.
Por último decir que el fertilizante se colorear� de verde o azul brillante, como es convencional, dando un aspecto de gran calidad. Finally, say that the fertilizer will be colored green or bright blue, as is conventional, giving a high quality appearance.
EJEMPLO DE REALIZACIÓN PRÁCTICA EXAMPLE OF PRACTICAL REALIZATION
A modo meramente ejemplario, para obtener una muestra de fertilizante en forma de gel, se ha llevado a cabo el proceso descrito anteriormente, mediante la participación de los siguientes componentes en % en peso: By way of example, to obtain a sample of fertilizer in the form of a gel, the process described above has been carried out, through the participation of the following components in% by weight:
- --
- Agua: 21,96% Water: 21.96%
- --
- Urea: 73,20% Urea: 73.20%
- --
- Acido fosforoso: 4,39% Phosphorous acid: 4.39%
- --
- Goma xantana: 0,22% Xanthan gum: 0.22%
- --
- Alcohol isoprol�tico: 0,22%. Isoprolytic alcohol: 0.22%.
- --
- Colorante azul 0,01%. 0.01% blue dye.
A partir de estos componentes, y partiendo de un agitador cilíndrico, se aplica sobre el mismo la cantidad total de agua que va a formar parte del fertilizante. From these components, and starting from a cylindrical agitator, the total amount of water that will be part of the fertilizer is applied on it.
Sin dejar de agitar en ningún momento, se aplica lentamente la urea y el ácido fosforoso, con lo que se forma una disolución sobresaturada y una suspensión con la urea que no se ha conseguido disolver. While stirring at no time, the urea and phosphorous acid are slowly applied, thereby forming a supersaturated solution and a suspension with the urea that has not been dissolved.
En recipiente aparte, se mezcla la goma xantana, en forma de polvo, y el alcohol al intermedio anterior. In a separate container, the xanthan gum is mixed, in powder form, and the alcohol in the previous intermediate.
Esto produce un incremento inmediato de la viscosidad de la mezcla, formándose un gel, de manera que las partículas que no se hayan disuelto no se van al fondo, sino que se quedan en suspensión en el seno del gel. This produces an immediate increase in the viscosity of the mixture, forming a gel, so that particles that have not dissolved do not go to the bottom, but remain in suspension within the gel.
La mezcla se agita durante al menos dos o tres horas, para finalmente aplicarle el colorante en orden a hacer el producto mas atractivo a la vista. The mixture is stirred for at least two or three hours, to finally apply the dye in order to make the product more attractive to the eye.
El producto obtenido se deja reposar durante un periodo comprendido entre 24 y 48 horas, tras el que est� listo para ser envasado y comercializado. The product obtained is allowed to stand for a period between 24 and 48 hours, after which it is ready to be packaged and sold.
