Freeze‐drying is a widely used drying technique in pharmaceutics, biologics, and food industries. It is a preferred drying technique when dealing with temperature‐sensitive chemicals/substances, as it can produce dry powders or cakes for easy storage and transport. From the perspective of pharmaceutical applications, the freeze‐dried products should also have a reasonable shelf life and be readily reconstituted with the anticipated drug activity [14].
