A system for preventing the escape of moisture from a beverage preparing device, such as a coffee brew basket, into apparatus for delivering a dry particulate food product, such as a coffee grinder, to the device during the beverage preparing process. The system includes a support plate containing a rectangular opening. A brew basket can be removably suspended from the plate under the opening. An elongated rod, rotatable about its longitudinal axis, is connected across the plate so as to extend across an edge of the opening. A flap is fixedly attached to the rod for tilting as the rod rotates between a closed position in which the opening is sealed against moisture penetration and a downwardly extending position such that the food product can be delivered through the opening to the basket. A spring biases the rod to an angular position of rotation such that the flap is normally closed to seal the opening. A solenoid mounted on the plate is linked to a lever arm on the rod which, when activated, rotates the rod in opposition to the spring to tilt the flap to the open position. A guide hood directs ground coffee ejected from the grinder through the opening into the basket when the solenoid is activated and the flap is open. Upon deactivation of the solenoid, the spring returns the flap to the closed position.
