Adding Food Waste
- Open the lid of the composter.
- Place your food waste into the inner barrel. Ensure not to overfill beyond the maximum fill line.
- Close the lid securely.
Selecting a Composting Mode
The composter offers three operational modes:
- Auto Mode: The composter automatically detects the weight of the food waste and adjusts the processing time (typically 4-6 hours).
- Manual Mode: Allows you to manually select a processing time between 1 and 6 hours.
- FMT (Ferment) Mode: After a regular composting cycle, you can use this 10-hour mode to further ferment the dried output into nutrient-rich plant fertilizer. This requires adding approximately 50% water (e.g., 400g water for 800g treated waste) to the treated waste before starting the FMT cycle.
