Freeze Dryer

The Focus Shot of Cirno from the world shrouded in scarlet mist (a Touhou LW original). She attacks by freezing and drying the moisture in the air. In winter, temperatures are low, and the air is dry. A food processing method uses this weather called kanzarashi, which maintains the texture and taste but also preserves the food longer. Apparently, a similar processing method has been used for space food.
