Floor Model Manifold Freeze Dryers are very important during the freeze-drying process because the morphology and size of the ice crystals formed during freezing and the degree of vitrification not only affect the subsequent drying rate, but also the quality of the freeze-dried drug. Therefore, the formulation, freezing rate, freezing method, and annealing should be considered during the Freeze Model Manifold Freeze Dryers freezing process....
The application of food vacuum freeze dryer on fresh red dates, the smaller the ice crystal formed by the internal water, the smaller the damage to the fresh jujube structure....
