Abstract
A grinding apparatus intended for domestic use in making nut butter from nuts such as peanuts can be constructed so as to utilize a housing containing a motor. The motor shaft is used to support a lower assembly and to drive a lower grinding disk forming a part of this assembly. An upper assembly is movably mounted on the lower assembly in such a manner that the relative position of an upper grinding disk relative to the lower grinding disk can be adjusted or varied in order to obtain what may be referred to as a "smoothly ground" product or what may be referred to as a "chunky ground" product consisting of particles ground to various different sizes. An actuator is provided for moving the upper assembly so as to obtain either of these types of products. A hopper structure is used to convey nuts or other material to be ground through the upper assembly to a space between the two grinding disks. This hopper and the upper assembly are constructed so as to accomodate the relative movement of the upper assembly without the possibility of the material to be ground being conveyed by the hopper to other than the interior of the upper assembly.
