Say kompleton vacuum freeze-pamaga et tugyopen na duaran manunan yugtan: pre-freezing tan sublimation drying. Say proseso na sublimation et mangekal ed saray kristal na yelo ed loob na saray materyales, bangta say pre-freezing et mandetermina ed inkaapag-apag tan kabaleg na saray kristal na yelo antis ya mamagaan. Anggano say freeze dryer et mankikimey ya maong ed sublimation phase, saray problema ed kalidad ya sengegan na agsuston pre-freezing et mansiansia ed saray asumpal lan produkto.
No say temperatura antis na yelo et mas atagey nen say material eutectic point odino say thermal holding time et kulang, say libren danum ed loob na raw materials et ag sigpot ya magmaliw ya solidon yelo. Diad silong na atagey a kondisyon na vacuum, say ag-onyelo ya likidon danum et natunaw tan onalis, ya pansengegan na iyabeba na materyal, inkaawet na tapew tan inkagba. Saray prutas ya atagey so asukar da a singa say strawberry tan mangga et mainomay ya na-supercooling. Say tapew to et singa nanyelo, bangta say loob to et wala ni ray likidon kabiangan, ya mairap ya naromog diad simplin panag-obserba.
Say kapeles na panyelo so mangitarok met na mapatnag iran pandumaan ed saray katangian na produkto. Say ultra-maples ya panyelo et mamawala na dakel ya angkekelag ya kristal na yelo. Kayari na sublimation, saray pore channels ed loob na saray materyales et mainget, kanian matantan so rehydration na saray asumpal lan produkto. Say medyo matantan ya panyelo et nayarin manporma na angkakabaleg iran kristal na yelo. Kayari na ice sublimate, mas malapar iran pores so mansiansia, ya epektibon mamaaligwas ed kapasidad na rehydration. Balet, say alablabas ya matantan ya panagyelo et maneral na saray cell wall na saray raw materials, pansengegan na ipaway na duga tan pakaandi na saray aktibon ingredients.
Saray nanduruman hilaw a materyales kaiba lay karne, saray bulong na pisipising, saray berry tan saray lamot na tanaman et walaan na nanduruman eutectic points tan tissue characteristics. Anggapoy unibersal ya pre-freezing parameter ya matukoy ed amin ya materyales. Saray propesyonal a pabrika et kaukolan dan gawaen iray melag a proseso na panagsukimat unong ed saray kategorya na produkto ra antis na dakel a produkto, usisaen iray malet a temperatura tan saray parametro na panag-hold, tan pabiskegen iray matatken lan pre-freezing curves diad control system.
Say in-optimize ya pre-freezing technology et epektibon mamawas ed saray kaslakan ya depekto kaiba lay pan-browning, fragmentation, collapse tan makapuy ya rehydration. Saya so mamaaligwas ed ani na asumpal a produkto, mamapabiskeg ed batch-to-batch consistency, mamabiskeg ed kompetisyon na produkto ed saray merkado ed biek-taew, tan mamawala na babaleg a tubo parad saray freeze-dried food processing enterprises.
