ABSTRACT OF THE DISCLOSURE A device for the wet treating of seed material includes a rotation-symmetrical treating chamber assembled of a conically shaped, downwardly sloping upper wall and of a frustoconical downwardly sloping bottom wall defining a central discharge opening. A circumferential annular gap connects the upper surface of the upper wall with the inner surface of the lower wall. A spraying device for a treating liquid is arranged in the treating chamber. Seed material is fed from a storage container through a gravity pipe arranged concentrically above the upper wall of the treating chamber. A dosing pipe surrounding a lower part of the gravity pipe is provided near its lower end with an internal expan- sion having an annular bottom surface and a discharge opening, the diameter of which at most slightly exceeds the inner diameter of the gravity pipe. The dosing pipe is guided for limited coaxial displacement relative to the gravity pipe. A deflecting surface is disposed concentrically below the discharge opening of the dosing pipe, which is supported via resilient energy storing means perman- ently urging said dosing pipe into a rest position, in which the annular clearance between the deflecting surface and the lower end of the dosing pipe has a predetermined breadth. The energy storing means and the dimensions of the expansion are mutually adjusted such that during operation the weight of the seed material collected on the annular bottom surface of the expansion automatically regulates the breadth of the annular clearance to provide a uniform flow rate of the seed material.
