An automatic metering device for powdery bulk material, in particular coffee powder, has a reservoir (1) with a wall (2) and a stationary base plate (3) for the bulk material. The base plate (3) has an opening (4) to a conveyor tube (5) which is disposed below said plate and in which a conveyor member (6) is disposed for conveying the bulk mate- rial to a delivery location. According to the invention, the wall (2) of the cylin- drical reservoir (1) is rotated during the metering process, and a sensor is pro- vided for determining the amount to be delivered by the conveyor member. The appliance of the invention enables bulk material, in particular coffee powder, to be metered simply and accurately with- out the risk of bridges forming inside the reservoir such that the bulk material poured in first is also dispensed first.
L'invention concerne un doseur automatique pour produit pulvérulent en vrac, notamment du café moulu, qui comprend un réservoir (1) comportant une paroi (2) et une plaque de base (3) fixe, pour le produit en vrac. La plaque de base (3) comporte une ouverture (4) donnant sur un tube convoyeur (5) placé dessous et dans lequel se trouve un élément convoyeur (6) qui achemine le produit en vrac jusqu'à un point de distribution. Selon l'invention, il est prévu de faire tourner la paroi (2) du réservoir (1) cylindrique pendant le processus de dosage et un détecteur sert à déterminer le volume de poudre que l'élément convoyeur doit distribuer. Selon l'invention, cet appareil permet de doser de manière précise et simple le produit en vrac, notamment du café moulu, sans risques de formation de ponts à l'intérieur du réservoir, le produit en vrac versé en premier ressortant également en premier.
