Prensip friz-siye nan seche rad friz

Freeze-drying principle of vacuum freeze dryer: The freeze-drying process is also the sublimation process of liquid water. Water has three aggregation states, namely the liquid state, solid-state, and vapor state. Based on the three-phase equilibrium theory of water, it can be known that the temperature of the triple point of water (the coexistence of vapor, liquid, and solid) is 0.0098℃, and the pressure of the triple point is 609.3Pa. Vacuum freeze-drying is carried out below the triple point. Freeze-drying is to use the principle that when the pressure is lower than the triple point pressure, the ice crystals absorb heat and directly convert it into Vapè vapè dlo a friz materyèl fre nan tanperati ki ba nan machin nan vakyòm friz-siye. Anba eta a vakyòm segondè, lè l sèvi avèk karakteristik sa yo sublime nan dlo, dlo a nan materyèl la ka dirèkteman sublime nan vapè dlo nan eta a glas san yo pa fonn glas, pou ke materyèl la ka friz-seche.

During vacuum freeze-drying, the temperature of the heating plate, the temperature of the material, the temperature of the condenser, and the vacuum℃of the drying chamber all change with time, and any one or several links may become the "bottleneck" of the drying process. In order to ensure the feasibility of the freeze-drying process and process qualified freeze-dried products, during the freeze-drying process, the temperature Nan pwodwi a ak plak la, tanperati a nan kondansateur a, ak degre nan vakyòm yo trase nan yon koub, ki te rele yon koub friz-siye . Lè diferan friz-siye koub yo te itilize pou pwodwi a menm, bon jan kalite a nan pwodwi a se tou diferan; Pwodwi diferan, diferan vakyòm friz-seche ak karakteristik sa yo nan materyèl la nan frizè, ak kondisyon opere diferan tou aplike diferan friz-siye koub . Menm si se yon pwodwi ki kalifye jwenn, done yo ta dwe analize bay yon baz pou plis optimize . chwazi yon pwofil ki apwopriye {a se yon pwofil la ki gen rapò ak {}}}}}}}.
