NOVELTY - Device (10) comprises an apparatus (4) for introducing dry feed into a fermenter (2), a storage tank (16) for the dry feed, a filling level monitoring equipment, preferably a weighing device (20) for determining a dry feed template amount of the dry feed present in storage tank, at least one dry feed supply device and control device, where the storage tank controlled by at least one dry feed supply device is filled with dry feed from a dry feed reservoir. The control device is designed for an automatic refilling of the storage tank via at least one dry feed supply device.    USE - The storage tank of the device is useful for feeding a fermenter of a biogas plant with automatically and manually filled dry feed (claimed).    ADVANTAGE - The device ensures a flexible, simple and high-volume feeding of the fermenter, and allows wet fermentation of biogas plant.    DETAILED DESCRIPTION - Device (10) comprises an apparatus (4) for introducing dry feed into a fermenter (2), a storage tank (16) for the dry feed, a filling level monitoring equipment, preferably a weighing device (20) for determining a dry feed template amount of the dry feed present in storage tank, at least one dry feed supply device and control device, where the storage tank controlled by at least one dry feed supply device is filled with dry feed from a dry feed reservoir. The control device is designed for an automatic refilling of the storage tank via at least one dry feed supply device, when the dry feed template amount including a manually filled dry feed quantity drops below a preset or pre-adjustable threshold value. The storage tank comprises at least one filling input for at least one dry feed supply device, and an opening for filling manually. The control device is designed to detect a manual filling of the storage tank, the automatic refilling of the storage tank and/or to customize the manual filling of feed of the fermenter.
