This depends primarily on how often and how much organic waste is disposed of. The moisture in the organic waste has a significant impact on the drying time. If you frequently put large amounts of wet organic waste into soilkind, this can lead to a longer drying time.
In addition, you should regularly clean the lint sponge. A clogged lint sponge can affect the airflow in the composter and slow down drying. So clean the sponge regularly to ensure that air circulation is optimal.
If the drying chamber is filled too full or if large quantities (more than 2 liters) of waste are put into the device at once, the fresh air inlet in the drying chamber may become blocked. In this case, drying will take longer than usual.
Also make sure that the activated carbon cartridge is filled and assembled correctly.
Make sure the sealing screen is firmly in place and free of activated carbon pellets, otherwise these could impair ventilation.
