  • protsess, mille käigus aurustatakse külmutatud materjalist jää, ilma et vahepeal moodustuks vesi
  • a method of drying foodstuffs, blood plasma, pharmaceuticals, etc. while retaining their physical structure, the material being frozen and then warmed in a high vacuum so that the ice sublimes
  • a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase
Good to know
  • The process consists of three separate, unique, and interdependent processes; freezing, primary drying (sublimation), and secondary drying (desorption).
  • The material is frozen, placed under a high vacuum, and maintained at a low temperature (−40°C or below). The pressure generated by the vacuum causes the ice to turn from a solid to a gaseous form without passing through a liquid state. This allows the removal of water from the material without otherwise disturbing its composition. Freeze drying is used to preserve tissues (e.g. blood plasma) and foods and to concentrate solutions.
külmkuivatamine
Usage examples
  • Külmkuivatamine ehk sublimatsioonkuivatamine on NASA teadlaste täiustatud tehnoloogia, mille käigus aurustatakse külmutatud materjalist jää, ilma et vahepeal moodustuks vesi.

  • meetod objektide dehüdreerimiseks/vee eemaldamiseks, mille põhimõte on märja materjali külmutamine külmkuivatis.[1] Külmkuivatamine on kolmeastmeline protsess, mille käigus muudetakse vesi tahkeks (jääks), seejärel toimub vee sublimeerumine gaasiks ning kolmandas faasis eemaldatakse gaasiline vesi täielikult objektist ning seda nimetatakse desorbtsiooniks.[2] Külmkuivatamine on effektiivne konserveerimismeetod ilma materjali kahjustamata, sobib näiteks arheoloogiliste orgaaniliste esemete, sealhulgas puidu, naha ja tekstiili konserveerimisel[3] 1.

  • puhaste, kitsa granulomeetrilise koostisega (sh keraamiliste oksiidipulbrite) tootmisprotsess/-operatsioon, mille olulisemad etapid on metallisoola (peam. sulfaadid) vesilahuse valmistamine, kiire allajahutamine ning jää eemaldamine vaakumsublimatsiooni kasutades
  • a method for production uniform particles sizing of pure, homogenous powder by separation of solids from suspension, or salts from solution; the suspension is rapidly frozen and then ice or solid solvent is removed by sublimation
  • технология получения чистого гомогенного по составу порошка узкой фракции выделением твёрдых частиц из суспензии или солей из раствора, что минимизирует агломерацию порошка; суспензию быстро замораживают, после чего лёд или твёрдый растворитель удаляют путём вакуумной сублимации
