The present invention is directed to a rotary press (1) for compressing a pressing food material (M), like food powder, into food tablets (T), comprising a feeding system (2) comprising a feeder (20) for continuously supplying the pressing food material (M) and a feeding pipe (21) for providing the pressing food material (M) received from the feeder (20), a press system (3) comprising a rotary die plate (30) being drivable about a rotational axis (R) and comprising a plurality of die cavities (31) for successively receiving an amount of pressing food material (M) provided by the feeding pipe (21) and to produce food tablets (T) inside the die cavities (31) by means of punches (32) upon a rotational movement of the die cavities (31) of the rotary die plate (30) with respect to the feeding system (2), a sensor arrangement (4) for detecting the fill level (L) of the pressing food material (M) in the feeding pipe (21), and a control unit (5) configured to control a feeding speed of the feeder (20) for continuously supplying the pressing food material (M) based on the detected fill level (L) to keep the fill level (L) at a defined fill level set point (LSP). The present invention is further directed to a method for pressing a food tablet (T), like a bouillon cube, by compression of a pressing food material (M), like a food powder, with a rotary press (1).
