This application describes a compact grinder that allows scooping particulate material to be ground (such as coffee beans), grinding the material to a controlled and consistent size, while concurrently emitting the stream of grinds directly into a receptacle, such as a coffee filter or the receptacle for an automatic coffee maker. The scoop portion of the grinder is sized to fit into the standard bags used for whole bean packaging, eliminating the need for a separate storage vessel or the need to pour the beans from their bag into the grinder. It has calibrated markings within the scoop, eliminating the need for a separate measuring device.
