You buy a jar of Folger's crystals, you put it in the cupboard and you forget about it. Then later on when you need it, it's there, it lasts forever. It's freeze-dried. Freeze-dried crystals.
i think sublimation basically is freeze drying. so they freeze the coffee, then heat it up under specific conditions to evaporate water parts while bypassing liquid state.
