摘要：
A vacuum freeze-drying apparatus capable of rapid drying is provided. A cold trap for drying, which is arranged inside a drying chamber, is set to a low temperature of −70 degrees Celsius or below, and heat is supplied to frozen particles on a conveyor belt to a degree such that the frozen particles do not melt. The amount of the liquid component evaporating from the frozen particles increases, and the amount of the liquid component entering the frozen particles decreases so that the time for drying the frozen particles is shortened.
