ABSTRACT:
An apparatus for the preparation of ground material used to make a beverage includes an electrostatic precipitator to prevent the separation of chaff fines from a main stream of the ground material. The apparatus includes a grinder and a chute leading from an exit opening in the grinder to a receptacle for receiving the ground material. The electrostatic dissipator is positioned near the exit opening for minimizing the electrostatic charge on chaff fines created by the grinder, thereby preventing the separation of chaff fines from the main stream of ground material.
