Drying: First, pre-cool the cold trap to -35℃, open the door of the drying chamber, put in the frozen lychees, close the door, and start the vacuum unit for evacuation. When the vacuum degree reaches 60Pa, the heating starts. Stable working vacuum, and ensure that the maximum temperature of the item does not exceed 50 ℃.
