Abstract: The grains-removing device comprises grains-removing members moved between a raised neutral position and a lowered grains-removing position, and a position sensor (01), by which the position of the grains-removing member is detected in one position. The spent grains are conveyed out of the lauter tun by rotationally driving the grains-removing member that is arranged in the grains-removing position. The position sensor cooperates with a transmission unit. The sensor data of the position sensor are wirelessly transferred to a stationarily mounted receiver unit from the transmission unit. The grains-removing device comprises grains-removing members moved between a raised neutral position and a lowered grains-removing position, and a position sensor (01), by which the position of the grains-removing member is detected in one position. The spent grains are conveyed out of the lauter tun by rotationally driving the grains-removing member that is arranged in the grains-removing position. The position sensor cooperates with a transmission unit. The sensor data of the position sensor are wirelessly transferred to a stationarily mounted receiver unit from the transmission unit for the description of the position of the grains-removing member and are then transmitted to a controller from the receiver unit. An electromechanical generator unit is provided for supplying the transmission unit with electrical energy. Mechanical drive movements are converted into electrical power supply with the generator unit. Position movements of the grains-removing device are transferable as the drive movements directly or indirectly to the generator unit by a transmission device. The generator unit comprises a piezoelement for converting the drive movements into electrical power supply. The position sensor and the grains-removing device are fastened at a rotatably drivable chopping system of a lauter tun. The transmission device comprises a drive cam (05), which is displaced during the displacement of the grains-removing device and engages with a tappet (06), which transfers the position movements of the drive cam to the piezoelement. The receiver unit is arranged outside of the lauter tun, is formed in a type of a rod antenna, a throw-out antenna or an adhesive antenna, and is arranged at a sight glass of the lauter tun, at a manhole cover of the lauter tun or at a cover glass of a lighting device of the lauter tun. The arrangement of the grains-removing member in the neutral position and/or the arrangement of the grains-removing member in the grains-removing position are detected with the position sensor. The position sensor is provided at each of the grains-removing members, so that the position of each grains-removing member is individually detected. An indicator is controlled with the sensor data of the position sensor, so that the determined positions of the grains-removing member are signalized at the indicator. A fault indicator is controlled with the sensor data of the position sensor, so that a false position of the grains-removing member is signalized at the fault indicator. The sensor data of the position sensor are transferred to the controller of the lauter tun, where the controller scans the position of the grains-removing member and controls or regulates the processes in the lauter tun.
