专利说明:

The object of the present invention is a modular and easily transportable method and plant intended for the dosing, mixing and packaging of powdery, granular and other products of similar characteristics and comprising a supporting structure that incorporates a plurality of modules that interact with each other. to obtain a mixed and packaged product ready for commercialization, and which comprises as main feature the incorporation of cooling and drying means of the mixed product.
The present invention falls within the technical sector of industrial plants for the manufacture of mixing and packaging of powdery products such as those used in the agri-food industry, without being therefore limiting in its application to other products of similar characteristics in other industrial manufacturing sectors. . State of the art
Traditionally, in the plants and machines for mixing powdered products different processing phases are described through which the product passes to be mixed vertically, that is, from one phase to another the product runs by gravity, from the top of the plant towards the bottom, as described, for example, in the Spanish patent with application number P0381423 which describes a machine for the treatment or mixing of powdered, granulated or pasty products.
To solve this problem, the European patent EP2465780 describes a mobile dosing, mixing and packaging plant that can be a mobile plant capable of dosing, mixing and packaging powdered, granular or similar products, can be transported in an approved shipping container of 40 feet and where all its structure, including all the necessary machinery, necessary elements and tools is distributed horizontally. In addition, this document describes a mobile plant whose operational control is carried out remotely, ensuring total control of the product and its traceability, providing


real-time connection with a control center arranged for this purpose in a place other than the mobile plant itself.
However, the plant described in EP2465780 lacks means of cooling and drying the mixed product, so its functionality is limited. This is essentially due to the fact that this patent is only possible for mixing powders, and it is desirable to carry out other processes. Description of the invention
It is an object of the present invention a method and a mobile modular plant that, based on the concept described in the patent EP2465780 improves its functionality and modularity in such a way that the possible uses thereof and, therefore, its versatility are increased, up to Become a multifunctional plant. Thus, the present invention describes a multifunctional plant that mixes all kinds of products and not just powdered products, such as EP2465780. In the same way, the present invention allows the granulation of the mixed products.
Thus, on a mobile modular mixing and packaging plant for powdery products
or granular comprising a bearing structure of suitable dimensions for introduction into a standard maritime container and housing inside a manual receiving and weighing module, a material loading module, a mixing module and a packaging module in the that the automatic dosing modules are incorporated prior to the introduction of the formula and that it also incorporates an automatic formula loading module with an automatic bag opening system to automate the loading of raw material to the plant.
In addition, the mobile plant also incorporates a module for injection of liquids in powdered mixture, maintaining its final state in powder. The module is automated, so that it is possible to automatically dose the liquids in the mixture, up to ten liquids according to the previous requirement of the end user, with the ability to inject liquid up to 50% on the powder so that the powder form be maintained after injection with the conditions and parameters required by the final formulation, such as temperature,


stirring and pre-mixing of liquids.
Finally, the plant incorporates a packaging module depending on the type of packaging required by the end user, including, but not limited to, a bagging module of large bags, a bagging module of European type bag or any other type of packaging (such as for example sachets). In addition, the packaging module can incorporate an automatic palletizing module for that customer who needs to automate the end of line.
In all the modules described, a series of basic conditions are met to ensure compatibility with the plant as a whole, since all modules must be transportable in a 20 or 40-foot shipping container, depending on the type of module , with all the necessary machinery, auxiliary and useful elements included.
On the other hand, the modules must be pluggable and use (plug and play), that is, the modules must have the ability to be connected to the CPU that manages the whole plant for immediate use, which includes that the modules must be compatible both electrically and pneumatically.
In addition to the modules described, the multifunctional plant achieves precisely its greatest advantages by incorporating means for cooling and / or drying the mixture in the mixing module, more specifically, the mechanical part of the mixer has been modified to, taking advantage of its movements, incorporate a flow of a fluid (preferably air) from the fixed mechanical part until it is removed through the evolution of the lower part or lower lateral area of the container, all of this in an automated way. In the present invention it is an essential point to obtain a recirculation of the air in the container and, especially, in the evolution of the lower part thereof.
More specifically, the advantages of the solution described in the present invention are the following:
a) If inside the equipment, in a mixing position, for example, by rotating + 180º its position (therefore reversing its position with respect to the horizontal defined by the floor of the plant), and a fluid flow is incorporated (for example dry air) the mixture will be drying


solids that we process. This converts the mixing container, in addition to a fluidized bed dryer by means of air flow drying and, as indicated, by the recirculation of the air in the evolve of the lower part of the container.
b) If liquids are injected into the mixing container and in a horizontal position (that is to say in an angular position of 90º or 270º with respect to the horizontal defined by the floor of the plant) and, in addition, with a specific grille type agitator As a mixing tool for this new application, we give air impulses, creating a suction current at the bottom of the container, the operations called grajeado or granulate can be performed.
c) If a mixture of solids with low melting greases is in process within the equipment, where it is necessary to perform their mixing with temperature and humidity controlled conditions (this operation being very delicate due to temperature) can be performed a cold fluid stream passing through the equipment, and remove it from the bottom of the container. The equipment becomes a low temperature mixer cooler, even a cooling equipment for delicate solids such as grease. In this case, it should be taken into account that not only the temperature is important, but also the humidity conditions of the air that is introduced into the container must be taken into account. The air, before its injection, passes through a conditioner.
d) The equipment can realize, through an opening of the bottom, in fixed or variable position, connecting the exit of the container to a vacuum equipment, a vacuum dryer, or mixing under vacuum to avoid possible mixtures existing oxygen that invalidate the mixture. The equipment becomes a dryer under vacuum or a mixer under vacuum.
In summary, mixing equipment with the addition of automatic aspiration in the container and the fixed part of the installation has gone from being a mixer to a fluidized bed dryer;
or (b) a grader or granulator; or (c) a cooler; or (d) a dryer under vacuum. With this innovation our mixer becomes a multifunctional equipment.
