Abstract
Technologies for controlling food dehydration in a low-oxygen environment include a control device and an enclosed drying chamber. The control device receives sensor data from environmental sensors disposed within the drying chamber. A concentration of oxygen within the drying chamber is determined based on the received sensor data. The control device controls a valve to selectively feed an amount of a combustible gas to a burner assembly disposed within the drying chamber. The burner assembly is ignited by the control device and a flame is produced. The flame depletes the concentration of oxygen within the drying chamber to an initial oxygen concentration level. The control device controls another valve to feed an amount of non-reactive gas into the drying chamber to flush the drying chamber and further deplete the concentration of oxygen within the drying chamber to a lower oxygen concentration level. Other embodiments are described and claimed.
