Phase diagramFreeze-dryingAqueous solutions of glycine and tetrahydrofuran (THF) were frozen under variable conditions and subsequently annealed. The phases that resulted from this process were studied by X-ray diffraction, DSC and cryotemperature SEM. Under conditions achieved in common laboratory freeze...
The pre-freeze rate and vacuum sublimation drying process have no significant effect on entrapment efficiency.According to the pseudo-ternary phase diagram,we determined the prescription of microemulsion:the value of Km:6:1;medium chain triglyceride(MCT)/soybean oil:1:3;ratio of oil/drug:1:3000;...
FIG. 2 provides a non-limiting schematic diagram of a continuous freeze-drying process for liquid solutions, which performs controlled nucleation through vacuum-induced surface freezing; FIG. 3 provides a non-limiting schematic diagram of a continuous freeze-drying process for particle-based material ...
Geometry of the container used in the freeze-drying process. To make the simulation more interesting, a heater is placed under the vial so that it covers only half of the bottom of the container, producing uneven heating. In the beginning of the simulation (shown below), there is ice on ...
FIG. 4 is a flow diagram illustrating a method for energy recovery in a freeze-drying system in accordance with embodiments of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION The freeze-drying process includes at least a freezing stage, a primary drying (e.g., sublimation) stage,...
LG1.0 features is easy to clean, control and maintenance. It is operated via a PLC +HMI control system. All parameters are monitored and stored during freeze drying to provide full documentation of the process. This makes it possible to reuse the test with the same freeze drying characteristics...
Here, we prepared ultralight 3D-γ-MnOOH by simple hydrothermal treatment and freeze-drying process. Hydrothermal route is a relatively facile procedure under mild environments. Moreover, hydrothermal products have high crystallinity and controllable crystal size. It is easy to adjust the shape of the...
1.1真空冷冻干燥技术真空冷冻干燥技术(vacuum freeze-drying,简称冻干)是先将物料冻结到其共晶 点[1]温度以下,使物料中的水分变成固态的冰,然后在适当的真空度下,使冰直接升 华为水蒸气,通过真空系统中的水汽凝结器(捕水器)将水蒸气冷凝,从而在低温 低压下获得高品质干燥制品的技术[2]。真空冷冻干燥技术是真空...
