Abstract: A grain dryer for providing a controlled drying process through a housing. The housing has a path for grain to be dried such that the grain is dried as the grain moves along the path. The grain dryer also has a fan and heater assembly for supplying heated air to the path for drying grain in the path. The grain dryer can control the flow of grain along said path and has sensors disposed in predetermined positions so as to detect different fault conditions. The sensors generating corresponding fault signals in response to the detection of fault conditions. The grain dryer also has a controller operatively connected to the sensors, the controller is responsive to fault signals to initiate a predetermined shutdown procedure upon receipt of any one of the fault signals. A memory is operatively connected to the controller for electronically recording and identifying information concerning shutdown procedures initiated by the controller. The grain dryer controller controls the start-up of in a predetermined manner.

Abstract: A digital control system for a coffee bean grinder, particularly one with a dual hopper, which is conveniently programmable and automatically operable for selecting bean type and grinding with a high degree of accuracy bean quantities ranging from a few ounces (e.g., 3 ounces or less) for brewing a few cups of coffee, to large quantities (e.g., 2 pounds or more) for brewing several gallons of coffee. The invention may be confined entirely to a grinder, or may be incorporated in a brewing system consisting of a brewer and one or more grinder. The invention allows one grinder to accommodate one or more coffee grinders either of the same type or of different types (i.e., a brewer for making multi-cup quantities or urns for making gallon quantities).
