Patent ID: 7325967

Claim:
A system for measuring, dispensing and pneumatically delivering micro-ingredients to a feed ration comprising: a weigh hopper; a storage bin including an auger mounted thereto, said auger for metering a desired amount of a micro-ingredient into said weigh hopper; a scale mounted to said weigh hopper for determining the weight of the micro-ingredient metered into said weigh hopper from said auger, said auger being activated to meter the desired amount of the micro-ingredient based upon weight indicated by said scale; a transport line for delivering the micro-ingredient to the feed ration and to receive the micro-ingredient metered from said auger; an eductor mounted in line with said transport line; means for supplying pressurized air through said eductor and through said transport line, wherein said eductor facilitates movement of the micro-ingredient through said means for introducing and through said eductor into said transport line; and a discharge device having an upstream end attached to a discharge end of said transport line, said discharge device further including a housing body an inner tube placed within said housing body, said inner tube communicating with said discharge end for receiving micro-ingredients moving through said transport line, wherein a cylindrical shaped gap defines an open space between an outer surface of said inner tube and an inner surface of said housing body, said inner tube and said body each having a downstream end terminating substantially coterminous with one another, and wherein a flow of liquid is provided through said housing body and then through said cylindrical shaped gap whereby as said micro-ingredients exit said discharge device, said liquid concentrically surrounds said micro-ingredients.
