Abstract: A dispenser comprises a ground grain container positioned in a matching seat recess in a housing and at least one blade rotated by a motor in the housing and capable of transferring, on rotation, a measure of ground grains through a flow aperture in the container to an outlet in the housing seat recess. The container is removably fitted into the seat recess of the housing through the use of two rotary, mutual coupling elements located at the bottom of the container and at the base of the seat recess of the housing respectively, and connected to the blade and to the motor respectively. The container also comprises elements for closing the flow aperture when the motor is stopped and for opening it when the motor is started. The dispenser is particularly useful in automatic coffee machines.
