Artiklen \"Almindelige t\u00f8rremetoder til frugt og gr\u00f8nt i industriel produktion og deres fordele og ulemper<\/a>\" n\u00e6vner brugen af Varmer\u00f8r af kulfiber<\/a> til opvarmning og t\u00f8rring med infrar\u00f8d str\u00e5ling. Denne metode har flere fordele s\u00e5som kortere t\u00f8rretider, lavere energiforbrug pr. enhed og forbedret kvalitet af de t\u00f8rrede produkter. I dag vil vi dele mere detaljerede forskningsresultater om t\u00f8rring af frugt og gr\u00f8nt med infrar\u00f8d str\u00e5ling.<\/p>\n\n\n\n Lad os f\u00f8rst n\u00e6vne nogle af de internationale forskningsresultater om infrar\u00f8d eller fjern-infrar\u00f8d t\u00f8rring. Nowaks unders\u00f8gelse af t\u00f8rring af \u00e6bleskiver viste, at infrar\u00f8d t\u00f8rring under de samme t\u00f8rrebetingelser reducerede t\u00f8rretiden med 50% sammenlignet med varmluftt\u00f8rring. Sandu rapporterede, at ved en varmlufttemperatur p\u00e5 250 grader Celsius er varmefluxen ved konvektiv t\u00f8rring 0,9-2,0 kW\/m2, mens varmefluxen ved str\u00e5lingsopvarmning er 4,5-12 kW\/m2. Theriens forskning viste ogs\u00e5, at varmefluxen ved infrar\u00f8d t\u00f8rring er 6-10 gange h\u00f8jere end ved varmluftt\u00f8rring, hvilket bekr\u00e6fter, at infrar\u00f8d str\u00e5lingsopvarmning er betydeligt mere effektiv.<\/p>\n\n\n\n Desuden har mange forskere fundet ud af, at infrar\u00f8d t\u00f8rring eller en kombination af infrar\u00f8d og andre t\u00f8rringsteknologier i h\u00f8j grad kan reducere t\u00f8rretiden og energiforbruget for andre landbrugsprodukter. Afzals forskning viste, at kombinationen af fjerninfrar\u00f8d t\u00f8rring og konvektiv t\u00f8rring reducerede t\u00f8rretiden for byg med 60% og reducerede elforbruget med 40%-70%. Paakkonen fandt ud af, at det tog 24 timer at t\u00f8rre rosmarin fra et fugtindhold p\u00e5 60%-70% til 8% med varmluftt\u00f8rring, men kun 3 timer med infrar\u00f8d t\u00f8rring.<\/p>\n\n\n\n Ud over at forbedre energiudnyttelsen og t\u00f8rreeffektiviteten har unders\u00f8gelser ogs\u00e5 vist, at kombinationen af infrar\u00f8d eller fjern-infrar\u00f8d t\u00f8rring med varmluftt\u00f8rring eller konvektionst\u00f8rring kan forbedre kvaliteten af landbrugsprodukter, s\u00e5som h\u00f8jere n\u00e6ringsstofretention, bedre farveudseende og rehydreringsegenskaber. Sakis forskning i t\u00f8rring af guler\u00f8dder og gr\u00e6skar viste, at infrar\u00f8d t\u00f8rring havde lavere tab af C-vitamin, \u03b2-caroten og smagsstoffer. Paakkonens unders\u00f8gelse af rosmarin viste, at tilbageholdelsen af E-vitamin i produkter, der blev t\u00f8rret med infrar\u00f8d varme, var dobbelt s\u00e5 stor som i produkter, der blev t\u00f8rret med varm luft. Gabels sammenlignende unders\u00f8gelse af t\u00f8rring af l\u00f8gskiver med infrar\u00f8d og varm luft viste, at infrar\u00f8dt t\u00f8rrede l\u00f8gskiver bevarede bedre farve- og smagsstoffer.<\/p>\n\n\n\n Infrar\u00f8d eller fjern-infrar\u00f8d t\u00f8rring er dog ikke uden ulemper. Str\u00e5lingen har en meget lavere gennemtr\u00e6ngningsevne sammenlignet med mikrob\u00f8lger, og gennemtr\u00e6ngningsevnen afh\u00e6nger af det infrar\u00f8de lys' b\u00f8lgel\u00e6ngde; kortere b\u00f8lgel\u00e6ngder har st\u00f8rre gennemtr\u00e6ngningsevne og omvendt. Absorptionsb\u00e5ndene i de bagte materialer ligger dog for det meste i det mellemlange til lange b\u00f8lgel\u00e6ngdeomr\u00e5de, hvilket er en selvmodsigelse. For yderligere at forbedre den samlede t\u00f8rreeffektivitet skal infrar\u00f8d t\u00f8rring derfor kombineres med andre t\u00f8rringsteknologier. Derudover har nogle forskere brugt intermitterende infrar\u00f8de t\u00f8rremetoder til at afb\u00f8de problemet med svag gennemtr\u00e6ngning i infrar\u00f8d t\u00f8rring, hvilket markerer et gennembrud og fremskridt inden for t\u00f8rring af tykkere materialer.<\/p>\n\n\n\n Ved industriel anvendelse af infrar\u00f8d t\u00f8rring er det n\u00f8dvendigt f\u00f8rst at kontrollere den passende afstand mellem det materiale, der skal t\u00f8rres, og produktet. Hvis afstanden er for lille, kan det f\u00f8re til uj\u00e6vn t\u00f8rring og lokal forkulning i senere faser; hvis afstanden er for stor, reduceres absorptionen af den infrar\u00f8de str\u00e5lingsenergi. Desuden skal den samlede t\u00f8rringshastighed og det endelige slutpunkt for t\u00f8rringen valideres under bagningen. Disse parametre kr\u00e6ver kontinuerlig akkumulering af virksomheder for at perfektionere de infrar\u00f8de t\u00f8rreparametre for forskellige produkter. Derfor er det afg\u00f8rende at v\u00e6lge de rigtige kulfibervarmer\u00f8r, passende t\u00f8rreparametre og forbehandlingsteknikker til landbrugsprodukter for at opn\u00e5 produkter af h\u00f8j kvalitet. Disse faktorer skal styres af teorien om infrar\u00f8d t\u00f8rring og raffineres yderligere gennem praktisk anvendelse og forbedring.<\/p>\n\n\n\n Udforsk banebrydende t\u00f8rreteknologier med Global Quartz Tube, som er f\u00f8rende inden for innovative infrar\u00f8de t\u00f8rrel\u00f8sninger.
