The invention relates to a coffee grinder having a grinding mechanism and having a housing, which acts as a holder for at least one bearing bracket, by means of which the at least one grinder element is mounted rotatably relative to the housing, and which has a filling opening for coffee beans to be ground. The coffee grinder is distinguished by the fact that the housing is manufactured from titanium or a titanium alloy.

A grinding device for grinding food products, comprises a housing compartment, grinding means and a hopper removably associated with the housing compartment, wherein the hopper comprises a container having at least one selectively openable and closable lower aperture.

A multifunctional coffee bean grinder contains a motor. The motor has a driving shaft with a first coupling portion and a second coupling portion which simultaneously output power and are respectively connected to a first grinding unit and a second grinding unit. The first grinding unit includes a first fixed tooth member and a first movable tooth member, the first movable tooth member is connected with the first coupling portion so as to be driven by the motor to rotate for grinding coffee beans into flake-shaped powder particles. The second grinding unit includes a second fixed tooth member and a second movable tooth member, the second fixed tooth member is fixed to the body, and the second movable tooth member has a center connected with the second coupling portion so as to be driven by the motor to rotate for grinding coffee beans into three-dimensional granular powder.
