A supply device 1 for granular material, in particular fish food, consists of a store tank 2 and a discharge device equipped with a helical conveying wire 5 which can be rotated and which extends transversely from the store tank 2. In order to achieve a simple, low-maintenance construction in combination with reliable, optimally proportioned discharge which is not susceptible to failure, the conveying wire 5 is connected at one end to the rotational mechanism, while the other, free end protrudes in the direction of conveyance into a discharge tube 4 which is known per se and which is connected with a discharge hopper 3 of the store tank 2, the internal diameter of the discharge tube 4 and the external diameter of the turns of the wire differing by at least the average length of the units of the granular material. <IMAGE> |
