The freeze dryer offers two main modes:
- Normal Mode: Utilizes internal pre-made freeze-drying formulas for common items like fruits, vegetables, and meats. Simply select the corresponding recipe.
- Expert Mode: Allows users to add and customize freeze-drying formulas, providing precise control over temperature, ramp time, keep time, and vacuum settings.
For a demonstration of the software interface and recipe selection, watch the video below:

4.4 Monitoring Progress
The 7-inch touchscreen displays real-time information about the freeze-drying process, including temperature, vacuum level, and remaining time. You can monitor progress and make adjustments if necessary in Expert Mode.
4.5 Ending Freeze-Drying and Unloading Food
Once the freeze-drying cycle is complete, follow the instructions on the screen or refer to the 'Home Freeze Dryer Operation' video (Section 3.3) to safely turn off the machine and vacuum pump. Open the vacuum valve to release the air pressure in the chamber before unlocking and opening the door. Carefully remove the trays with the freeze-dried food.
