TITOLO TITLE
LIQUIDO REFRIGERANTE COOLANT
DESCRIZIONE DESCRIPTION
Il presente brevetto à ̈ attinente al settore della refrigerazione ed in particolare concerne un nuovo liquido per la refrigerazione di vari prodotti, specificatamente nel settore alimentare, medico eccetera. This patent relates to the refrigeration sector and in particular concerns a new liquid for the refrigeration of various products, specifically in the food, medical and so on sector.
E' noto il liquido refrigerante prediluito composto da glicole propilenico, inodore e incolore, chiaro e viscoso utilizzato quale liquido di raffreddamento in sistemi a raffreddamento liquido, quali motori, guarnizioni e altri componenti non metallici dei motori. Il punto di congelamento del glicole propilenico si abbassa quando viene miscelato con acqua a causa della rottura dei legami di idrogeno. Tale liquido à ̈ tossico. Sono noti contenitori parallelepipedi in materiale plastico, per il raffreddamento, contenenti un liquido miscelato con glicole propilenico che trovano largo impiego per il raffreddamento dell'ambiente interno di contenitori termoisolanti, impiegati soprattutto in luoghi privi di allacciamenti elettrici. Tali contenitori parallelepipedi, prima del loro impiego, vengono raffreddati e, in caso di rottura, devono essere gettati via. Sono noti i sacchetti in polivinile contenenti un fluido che, una volta raffreddato, mantiene a lungo la bassa temperatura per raffreddare le parti del corpo lese o per diminuire o mantenere bassa la temperatura dei cibi. Trattasi di strumenti che possono essere utilizzati più volte. Una volta che detto sacchetto si deteriora o si frattura, detto sacchetto deve essere gettato via. The prediluted coolant composed of odorless and colorless, clear and viscous propylene glycol used as a coolant in liquid cooling systems, such as engines, gaskets and other non-metallic components of engines, is known. The freezing point of propylene glycol lowers when it is mixed with water due to the breakdown of hydrogen bonds. This liquid is toxic. Parallelepiped containers made of plastic material for cooling are known, containing a liquid mixed with propylene glycol which are widely used for cooling the internal environment of heat-insulating containers, used above all in places without electrical connections. These parallelepiped containers, before their use, are cooled and, in case of breakage, they must be thrown away. Polyvinyl bags are known containing a fluid which, once cooled, maintains a low temperature for a long time to cool the injured parts of the body or to decrease or keep the food temperature low. These are tools that can be used several times. Once said pouch deteriorates or fractures, said pouch must be thrown away.
Sono noti refrigeranti chimici caratterizzati da sacchetti monouso formati da due reattivi separati fra loro e il cui effetto refrigerante viene attivato rompendo l'apposito separatore interno. Le sostanze interne reagiscono tra loro e determinano un rapido abbassamento della temperatura. Tale sistema contiene un liquido tossico in caso di contatto con il corpo umano. La capacità refrigerante di detto sistema ha una durata temporale limitata. Chemical refrigerants are known characterized by disposable bags formed by two reagents separated from each other and whose refrigerating effect is activated by breaking the appropriate internal separator. The internal substances react with each other and cause a rapid drop in temperature. Such a system contains a liquid that is toxic in case of contact with the human body. The cooling capacity of this system has a limited time duration.
Tali soluzioni note presentano alcuni problemi applicativi, quali il fatto che il ghiaccio, che ha una temperatura di pochi gradi sotto lo zero, si scioglie dopo un breve intervallo di tempo e deve essere sostituito. These known solutions present some application problems, such as the fact that the ice, which has a temperature of a few degrees below zero, melts after a short interval of time and must be replaced.
I fluidi citati sono nocivi al contatto diretto con cibi e con il corpo umano e devono comunque essere impiegati utilizzando sacchetti o appositi contenitori per evitare il contatto diretto con l'utente. The fluids mentioned are harmful in direct contact with food and the human body and must in any case be used using bags or special containers to avoid direct contact with the user.
Tali soluzioni hanno una durata temporale limitata e, trascorso un certo intervallo di tempo, debbono essere sostituite in quanto perdono la propria capacità refrigerante. These solutions have a limited time duration and, after a certain time interval, they must be replaced as they lose their cooling capacity.
Per ovviare a tutti i suddetti inconvenienti si à ̈ studiato e realizzato una nuova miscela refrigerante priva di componenti tossiche e, pertanto, atta ad essere impiegata per il raffreddamento di cibi e bevande nonché per essere applicata al campo medico e in molti altri settori a rischio salute. To overcome all the aforementioned drawbacks, a new refrigerant mixture without toxic components has been studied and created and, therefore, suitable for use for cooling food and drinks as well as for application in the medical field and in many other sectors. health risk.
Il nuovo liquido non à ̈ tossico e non produce effetti collaterali se ingerito. Inoltre, può essere impiegato direttamente al contatto con cibi e con la pelle, non causa ustioni e non danneggia il tessuto cutaneo. The new liquid is non-toxic and produces no side effects if ingested. Furthermore, it can be used directly in contact with food and skin, it does not cause burns and does not damage the skin tissue.
Il nuovo liquido può essere inserito in vasi o contenitori per raffreddare cibi, bevande e terminato l'impiego può essere recuperato, versandolo nuovamente nel contenitore originario per successivi utilizzi, anche domestici. The new liquid can be placed in jars or containers to cool food and drinks and, once it has been used, it can be recovered, pouring it back into the original container for subsequent uses, including domestic ones.
Il nuovo liquido, collocato in freezer, si raffredda per essere poi estratto alla temperatura del freezer che generalmente si avvicina a -20°C. The new liquid, placed in the freezer, cools down to be then extracted at the freezer temperature which generally approaches -20 ° C.
Il nuovo liquido può essere arricchito da coloranti di vari colori, ottenendo vari effetti cromatici e facilitando il suo riconoscimento. The new liquid can be enriched with dyes of various colors, obtaining various chromatic effects and facilitating its recognition.
Il nuovo liquido solidifica ad una temperatura inferiore a –20°C preferibilmente da – 25°C in giù. The new liquid solidifies at a temperature below â € “20 ° C preferably from â €“ 25 ° C down.
Il nuovo liquido à ̈ preferibilmente composto per il 75% in acqua, il 15% sale e il 10% in glicerina vegetale. The new liquid is preferably composed of 75% in water, 15% salt and 10% in vegetable glycerin.
Questa composizione consente al nuovo liquido refrigerante di solidificare a temperatura inferiore a – 20°C e di poter essere convenientemente utilizzato in forma liquida fino alla predetta temperatura. This composition allows the new coolant to solidify at a temperature below â € “20 ° C and to be conveniently used in liquid form up to the aforementioned temperature.
Modificando la predetta composizione e impiegando, per esempio, 700 grammi di acqua, 200 grammi di sale e 100 grammi di glicerina vegetale, il nuovo liquido solidifica a temperatura di circa –13°C, ovvero di –11°C se a quest'ultima composizione di aggiungono altri 100 grammi di glicerina vegetale. By modifying the aforementioned composition and using, for example, 700 grams of water, 200 grams of salt and 100 grams of vegetable glycerin, the new liquid solidifies at a temperature of about - 13 ° C, or - 11 ° C if to this last composition they add another 100 grams of vegetable glycerin.
Il nuovo liquido può essere inserito all'interno di un recipiente nel quale viene posta una bottiglia di vino o di una bibita. Il nuovo liquido, che à ̈ stato portato alla temperatura preferita ed à ̈ allo stato liquido e ad una temperatura di –15/-20°C, avvolge e viene a contatto con tutta la superficie della bottiglia, mentre nel noto sistema dei cubetti di ghiaccio, solo la parte sciolta cioà ̈ l'acqua, à ̈ a diretto contatto con la superficie della bottiglia, mentre la parte solida ghiacciata può toccarla solo marginalmente con ovvia minore efficacia refrigerante. The new liquid can be placed inside a container in which a bottle of wine or soft drink is placed. The new liquid, which has been brought to the preferred temperature and is in the liquid state and at a temperature of â € “15 / -20 ° C, wraps and comes into contact with the entire surface of the bottle, while in the well-known system of ice cubes, only the melted part, that is the water, is in direct contact with the surface of the bottle, while the frozen solid part can touch it only marginally with obvious less cooling effectiveness.
Il nuovo liquido inoltre può essere inserito all'interno di contenitori non rigidi per il raffreddamento di cibi e per il mantenimento degli stessi a una bassa temperatura. The new liquid can also be placed inside non-rigid containers for cooling food and for keeping it at a low temperature.
Altro importante vantaggio consiste nel fatto che, l'efficacia del raffreddamento nel tempo à ̈ molto maggiore rispetto ai sistemi noti, in quanto il nuovo liquido, partendo da una temperatura molto più bassa della nota miscela acqua-ghiaccio, avrà un delta di temperatura, costituito tra la differenza fra la temperatura del liquido e la temperatura ambiente, molto maggiore e pertanto la sua efficacia nel tempo sarà molto maggiore rispetto alla miscela acqua/ghiaccio. Another important advantage consists in the fact that the cooling effectiveness over time is much greater than the known systems, since the new liquid, starting from a much lower temperature than the known water-ice mixture, will have a temperature delta, constituted between the difference between the temperature of the liquid and the ambient temperature, much greater and therefore its effectiveness over time will be much greater than the water / ice mixture.
Il nuovo liquido può essere convenientemente impiegato per raffreddare il contenuto di bottiglie o lattine contenenti prodotti alimentari. The new liquid can be conveniently used to cool the contents of bottles or cans containing food products.
Anche nel trasposto di prodotti o parti che devono essere mantenute a temperatura molto bassa, il nuovo liquido avrà efficacia maggiore dei noti sistemi acqua/ghiaccio, in quanto, partendo da una temperatura più bassa, dura maggiormente nel tempo. Tale maggior efficacia potrà essere particolarmente sfruttata nell'ambito del trasporto di medicinali e organi umani. Even when transporting products or parts that must be kept at a very low temperature, the new liquid will be more effective than the known water / ice systems, since, starting from a lower temperature, it lasts longer over time. This greater effectiveness could be particularly exploited in the transport of medicines and human organs.
Il prodotto inoltre potrà essere venduto e conservato in semplici bottiglie di vetro o plastica nelle varie dimensioni ed utilizzato varie volte. Potrà essere reintegrato, in caso di perdite, mantenendo sempre la sua funzione di liquido raffreddante. The product can also be sold and stored in simple glass or plastic bottles in various sizes and used several times. It can be replenished in the event of leaks, always maintaining its function as a cooling liquid.
Queste sono le modalità schematiche sufficienti alla persona esperta per realizzare il nuovo liquido, di conseguenza, in concreta applicazione potranno esservi delle varianti senza pregiudizio alla sostanza del concetto innovativo. These are the schematic modalities sufficient for the expert person to realize the new liquid, consequently, in concrete application there may be variations without prejudice to the substance of the innovative concept.
Pertanto con riferimento alla descrizione che precede si esprimono le seguenti rivendicazioni. Therefore, with reference to the preceding description, the following claims are expressed.
