  • Patent number: 8561320
    Abstract: A method for determining status of a drying cycle comprises receiving, at a first time, a first signal from a bladder pressure sensor configured to be responsive to changes in a weight of a container of the dryer, the container retaining materials to be dried. At a second time, the controller receives a second signal from the bladder pressure sensor. A change in the bladder pressure signals is calculated based on difference between the second signal and the first signal, and the change in the bladder pressure signals is interpreted as a change in the weight of the container. Based on the change in the weight of the container and the length of time, a rate of change in the weight of the container is calculated.
