Definitions

• the subject of the present patent application for industrial invention is a process of elimination, by evaporation, of the residual vegetation water from the pressing of the olives, obtained by using, in a desiccation installation, spent and soaked olive marc of said waters.
• olive oil olive oil
• olive marc made up of all the peelings (skin, pulp and pressed pits) as well as vegetation water which contains about 15% organic substances and 2% mineral substances.
• the water was evaporated after having sprinkled it on the virgin olive marc, that is to say what remains after the first pressing of the olives; Indeed, the marc soaked, was introduced into a hot air cyclone, inside which was determined the evaporation of water and therefore the deposition of substances contained therein on the marc which successively left this same installation.
• olive marc was obtained which was particularly rich in gummy, resinous and similar components; components that are originally suspended in vegetation water. This olive marc was then sent to the factory to obtain olive marc oil.
• the oil mill is therefore forced, in this hypothesis, to sell virgin olive marc to the factory, a factory from which it will have to buy spent pomace to supply its own desiccation installations.
• the oil mill would not even have the advantage of separating the combustible component of its virgin olive marc from the non-combustible component on its own, as long as, if it is fair to say that in such a way he could produce the fuel necessary for his desiccation plants on his own, it must also be said that he could not sell to the factory the private marc of the kernel component since this component would be unsuitable to support the process of degreasing by means of the gasoline which is carried out in the said marc factories and which, effectively, cannot be carried out without the presence, inside the virgin olive marc, of this component of the pits which functions, practically, as an essential drainage element.
• the process of eliminating vegetation water according to the invention has been studied and developed.
• the process of evaporation of the discharge water from the oil mills should be carried out directly at the marc factory, using, as a vehicle to introduce vegetable water in the hot air cyclone, spent olive oil and no longer virgin.
• the marc factories would thus offer the oil mills the possibility of having the vegetable water removed with the virgin olive marc, which constitutes a very important advantage for the negotiation of the purchase of the marc olives from the marc factory which is able to offer this ancillary service compared to those who cannot provide it; in other words, it can surely be said that the marc factory which is also able to offer the service of removing the vegetation water could hope to obtain a sort of monopoly on the purchase of marc the oil mills , especially in those not still equipped to dispose of landfill on their own and who do not wish to provide an autonomous installation.
• a further advantage of the process according to the invention also derives, as regards the functional, from the introduction of what must be considered the most important and characterizing innovation over the entire operational sequence which leads to the evaporation of the waters. vegetation.
• this innovation consists in using exhausted marc inside the hot air evaporation cyclone, available in large quantities at the marc factory, instead of virgin marc.
• the spent marc having elapsed at the end of the degreasing process of the virgin marc necessary to obtain the marc oil, no longer has gummy components, resins or the like; this means that, in spite of the repeated passages in the hot air cyclone and the successive deposits of subsequent quantities of gums and resins which are carried out on the marc during the continuous phases of evaporation of the water which it conducts in the installation, the exhausted marc never risks producing, during repeated and violent reheating, the highly smelly exhalations characteristic of virgin marc.
• new spent marc will be obtained which may be partially saved for future landfill disposal processes and may be partially used during a successive phase of work.
• This subsequent operational phase consists in centrifuging the various components of the spent marc to obtain, as already explained, animal fodder and fuel for the desiccation installation in question, for the management of which, therefore, the factory marc will never have a problem given the abundance of marc available to use for this purpose.
• the vegetation water could be treated with products to prevent fermentation, such as for example Na2CO3 or NaHCO3 before being introduced into the hot air cyclone with the spent marc.
