A feed-in container for fluidizing and conveying products in dust form, such as, for example, coal dust, using conveying gases under pressures up to 7 MPa, in which the fluidizing floor is fastened by a central tubular supporting construction. A stable and low-outlay construction takes up the weight and pressure loading of the fluidizing floor. An emptying line is arranged in the supporting construction, making a separate opening through the fluidizing floor obsolete and thus providing a low-outlay passage through the fluidizing floor. The supporting construction is also designed such that it serves as a shaft guide for an agitator.
