Abrégé

The invention relates to a method performed by a control unit (100) for controlling a process of drying free-flowing particulate material (20) in a continuous dryer (10) which comprises an inlet (14) and an outlet (16). The method comprises receiving at least a first humidity value (Min) from a first humidity sensor (15) indicative of the moisture content of at least one layer of free-flowing particulate material entered into the dryer (10) via the inlet (14); receiving at least a second humidity value (Mout) from a second humidity sensor (17) indicative of the moisture content of the at least one layer of free-flowing particulate material when exiting out of the dryer (10) via the outlet (16); and controlling the speed of the free-flowing particulate material exiting out of the dryer (10) via the outlet (16) based on the received at least first and second humidity values (Min, Mout) and an internal set point for an average outgoing moisture content (A) regulated around an ideal average moisture level (B) set by a user of the control unit (100). The invention also relates to a control unit controlling such a process and a continuous dryer comprising such a control unit.

Abrégé

The present invention relates to a sampling device for the sampling and analysis of free flowing particulate material in a moving flow of said material, comprising a sample diversion device to divert part of the free flowing particulate material from the moving flow of free flowing particulate material to a measuring container having a volume X, as well as a measuring device arranged to record one or more chosen sample parameters of the free flowing particulate material. The sampling device further comprises a sample discharging device with a discharge channel and a calibration channel, wherein said sample discharging device is slidably arranged to cooperate with an outlet opening of the measuring container. The invention further relates to a method of using said sampling device as well as the calibration of the same.
