BACKGROUND ART
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Mill technology is very traditional. Typically, such machines comprise a cast iron housing with a pair of circular, pink granite grinding stones, spaced a preselected, small distance apart. One of the stones, commonly referred to as the "running stone," is turned by a shaft, while the other stone, the "bed" stone, remains stationary. Grain is fed into the mill from a hopper to a rotating auger, and then into the space defined by the distance between the opposing faces of the stones. After the grain is milled to flour, the flour is removed from the interior of the mill for collection and further processing.
[0004] One problem faced in the art is the durability of the moving components of the mill. In particular, the shaft can be seized by the cast iron ball bearing assemblies through which the shaft is journaled when frictional heat welds the bearings to the shaft. Also, vibration from the motor that turns the shaft along with misalignment of the running stone causes the turning shaft to deviate from its normal, horizontal position, resulting in interference, frictional heat buildup, and excessive wear. In addition, heat from friction can damage the grain, as will be explained below.
[0005] If the machine is run continuously, heat builds in the housing and heats the grain. When the grain becomes overheated, it begins to break down chemically. For example, when wheat embryo, or the wheat kernel, experiences a temperature of approximately 130° F. or greater, it loses its protein content. Furthermore, products made from overheated wheat flour are less flavorful. To limit heat buildup as well as prevent damage to moving parts, the running stone is rotated at a slower speed and for shorter periods of time to allow dissipation of the heat. However, neither of these solutions is acceptable, since both adversely affect the productivity of the grinding operation.
[0006] Therefore, there is a need in the art for a grinding machine that seeks to overcome short-comings highlighted above and utilize techniques, which are robust, portable, efficient, cost-effective system.
