Titolo: "Surgelatore istantaneo a neve in continuo per late ed altri liquidi" Title: "Continuous instant snow freezer for late and other liquids"
Descrizione Description
Premessa: Premise:
La macchina e'stata progettata con lo scopo di realizzare un processo tecnologico in continuo in grado di garantire la massima igienicita' ed al contempo di conservare intatte le proprieta'originarie del latte,cosa non consentita dalla tecnologia attua le. Infatti la nebulizzazione, generando goccioline finissime annulla quasi completamente il gradiente termico tra la parte acquosa e la parte solida in formazione , mentre il contatto diretto tra la corrente di aria prima compressa e poi espansa, per farla raggiungere una temperatura fino a -100?, genera istantaneamente dei soffici fiocchi di neve(non ghiaccio), che non alterano minimamente le struttura molecolare, preservando quindi tutte le proprieta'esistenti al momento del congelamento a condizione che non venga mai interrotta la catena del freddo (come naturalmente accade per tutti i prodotti surgelati). The machine has been designed with the aim of realizing a continuous technological process able to guarantee maximum hygiene and at the same time to keep intact the original properties of the milk, which is not allowed by the current technology. In fact, the nebulization, generating very fine droplets almost completely cancels the thermal gradient between the aqueous part and the solid part being formed, while the direct contact between the air stream first compressed and then expanded, to make it reach a temperature up to -100 ?, instantly generates soft snowflakes (not ice), which do not alter the molecular structure in any way, thus preserving all the properties existing at the time of freezing provided that the cold chain is never interrupted (as naturally happens for all products frozen foods).
I vantaggi che apporta tale innovativa tecnologia sono molteplici come ad esempio: The advantages that this innovative technology brings are many, such as:
1) Il surgelatore, essendo in continuo e istantaneo, pu? essere associato direttamente alla mungitura degli animali da latte (latte munto e surgelato). 1) The freezer, being continuous and instantaneous, can? be directly associated with the milking of dairy animals (milked and frozen milk).
2) Gli alimenti che soffrono le temperature ambienti durante le fasi di trasporto, stoccaggio e durante tutte le fasi dei programmi di produzione non saranno pi? condizionati dalla deperibilit? del prodotto. 2) Foods that suffer from ambient temperatures during the transport and storage phases and during all phases of the production programs will no longer be? conditioned by the perishability? of the product.
3) Eventuale utilizzo come tecnica ultrarapida di congelamento primario nel processo di liofilizzazione. 3) Possible use as an ultra-rapid primary freezing technique in the lyophilization process.
Descrizione del processo come riportato dalla Tavola A del disegno allegato: Description of the process as reported in Table A of the attached drawing:
1) L'aria ambiente viene compressa, attravero il compressore A fino a 7/8 bar, portandosi cosi'ad una temperatura fino a 430?, che ne garantisce una perfetta sterilizzazione. 1) The ambient air is compressed, through the compressor A, up to 7/8 bar, thus reaching a temperature of up to 430?, Which guarantees perfect sterilization.
2) L'aria viene fatta passare per il radiatore B che ne abbassa la temperatura a ca 50? e dopo aver attraversato il flussometro C (regolatore di portata), si porta al sottoraffreddatore D 2) Is the air passed through the radiator B which lowers the temperature to about 50? and after passing through the flow meter C (flow regulator), it goes to the sub-cooler D
che, scambiando calore con l'aria in uscita dal ciclone, la cui temperatura e'ca - 18?, ne abbassa ulteriormente la temperatura fino 20?. which, exchanging heat with the air leaving the cyclone, whose temperature is - 18?, further lowers the temperature up to 20 ?.
3) L'aria compressa e raffreddata passa attraverso gli ugelli U1 o U2 oll3 di espansione(ognuno ha una portata diversa) posti sulla testata del ciclone, con angolo di ingresso allo stesso ciclone calcolato in modo tale da assicurare la componente di forza verso il basso sui fiocchi generati, raggiungendo, per effetto della stessa espansione, una temperatura fino a -100?(diventando essa stessa fluido criogenico). 3) The compressed and cooled air passes through the expansion nozzles U1 or U2 oll3 (each has a different flow rate) placed on the cyclone head, with an inlet angle to the same cyclone calculated in such a way as to ensure the force component towards the low on the generated flakes, reaching, due to the same expansion, a temperature of up to -100? (becoming itself cryogenic fluid).
4) Il latte una volta aspirato tramite pompa esterna da una vasca di alimentazione E provvista di dispositivo di sicurezza per il troppo pieno, viene fatto passare attraverso gli ugelli nebulizzatori U4 o U5 o U6(corrispondentr alla portata degli ugelli di espansione, e, nebulizzato, si scontra nel ciclone F con la corrente di aria fredda, generando istantaneamente fiocchi di neve, che, per effetto della forza centrifuga e gravitazionale nonche'della particolare angolatura, come gi?' affermato, impressa agli ugelli stessi, cadono verso il basso, mentre l'aria fredda ritorna verso il compressore, come si vede chiaramente nella Tavola A del disegno allegato. 4) Once the milk has been sucked by an external pump from a feeding tank E equipped with an overflow safety device, it is passed through the spray nozzles U4 or U5 or U6 (corresponding to the flow rate of the expansion nozzles, and is sprayed , collides in cyclone F with the current of cold air, instantly generating snowflakes, which, due to the centrifugal and gravitational force as well as the particular angle, as already stated, impressed on the nozzles themselves, fall downwards, while the cold air returns to the compressor, as can be clearly seen in Table A of the attached drawing.
5) I fiocchi escono dalla bocca inferiore del ciclone e si depositano nel sacco di raccolta 5) The flakes come out of the lower mouth of the cyclone and are deposited in the collection bag
G, posizionato in basso, tenuto in posizione da un sistema meccanico di leveraggio. Una volta chiuso il sacco (in atmosfera modificata) sara'trasportato celermente in una cella adatta a prodotti surgelati. G, positioned at the bottom, held in position by a mechanical lever system. Once the bag is closed (in a modified atmosphere) it will be quickly transported to a cell suitable for frozen products.
6) La continuita'della produzione e' garantita dai flussi continui di aria e prodotto nebulizzato. 6) The continuity of the production is guaranteed by the continuous flows of air and nebulized product.
7)Tutta la macchina e' costruita in acciaio inox AISI 316, compreso gli ugelli ed inoltre e'racchiusa interamente in un mobile termicamente isolato(non riportato nella Tavola A del disegno allegato ma previsto), dotato di porte di accesso e finestra di ispezione, per assicurare le necessarie condizioni di adiabacita'del sistema. 7) The whole machine is built in AISI 316 stainless steel, including the nozzles and is also entirely enclosed in a thermally insulated cabinet (not shown in Table A of the attached drawing but provided), equipped with access doors and inspection window , to ensure the necessary adiabacity conditions of the system.
8) La macchina e' stata costruita in modo che la pulitura sia estremamente semplice come anche la sterilizzazione che e'assicurata da una innovativa lampada a plasma freddo, non riportata nella Tavola A del disegno allegato. 8) The machine has been built in such a way that cleaning is extremely simple as well as sterilization which is ensured by an innovative cold plasma lamp, not shown in Table A of the attached drawing.
