Method and apparatus for administering micro-ingredient feed additives to animal feed rations
First Claim
1. 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;
means intermediate said weigh hopper and said transport line for introducing the micro-ingredient in the transport line;
an eductor mounted in line with said transport line; and
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.

Abstract
A method and apparatus are provided for administering micro-ingredient feed additives to animal feed rations. The apparatus may be referred to as a system which includes a number of discrete components which cooperate together to ultimately deliver micro-ingredients to a desired location, such as a feed mixer containing a feed ration. Structure is provided for storing, measuring, dispensing, and pneumatically conveying the micro-ingredients. Measuring of the micro-ingredients may be achieved by loss in weight, gain in weight, or volumetric metering methods. Pneumatic transport may be achieved either by a single transport line, or a plurality of transport lines. The system is operated by a control unit which controls components of the system to achieve delivery of specified amounts and types of micro-ingredients to the feed ration.

10. A method of measuring, dispensing, and pneumatically delivering micro-ingredients to a feed ration, said method comprising the steps of:
-
providing a bin for storing a quantity of a micro-ingredient;
metering the micro-ingredient from the bin to a weigh hopper;
weighing the micro-ingredient in the weight hopper;
providing a transport line and an eductor placed in line with transport line;
pressurizing the transport line and eductor by a source of pressurized air;
operating the eductor to draw the micro-ingredient from the weigh hopper and into the transport line; and
pneumatically transferring the micro-ingredient to the feed ration without the addition of liquid to the micro-ingredient while the micro-ingredient is in the transport line, bin and hopper. - View Dependent Claims (11, 12, 13, 14)

15. A method of measuring, dispensing, and pneumatically delivering micro-ingredients to a feed ration, said method comprising the steps of:
-
providing a storage bin for storing a quantity of a micro-ingredient;
metering the micro-ingredient from the bin to a means for temporarily storing the metered micro-ingredient;
recording the loss of weight in the bin after the micro-ingredient has been metered to the means for storing, the recorded loss of weight corresponding to the amount of the micro-ingredient metered to the means for storing;
providing a transport line and an eductor mounted in line with the transport line;
pressurizing the transport line and eductor by a source of pressurized air;
operating the eductor to draw the micro-ingredient from the means for storing into the transport line; and
pneumatically transferring the micro-ingredient to the feed ration, said transferring step being achieved without the addition of liquid in the transport line, bin, and hopper. - View Dependent Claims (16, 17, 18)

19. A method of measuring, dispensing, and pneumatically delivering micro-ingredients to a feed ration, said method comprising the steps of:
-
providing a storage bin for storing a quantity of a micro-ingredient;
metering the micro-ingredient from the bin to a means for temporarily storing the metered micro-ingredient, said metering step resulting in delivery of a predetermined and desired quantity of the micro-ingredient to the means for storing;
providing a transport line and an eductor mounted in line with the transport line;
pressurizing the transport line and eductor by a source of pressurized air;
operating the eductor to draw the micro-ingredient from the means for storing into the transport line; and
pneumatically transferring the micro-ingredient to the feed ration, without addition of liquid to the micro-ingredient while the micro-ingredient is in the bin, hopper and transport line. - View Dependent Claims (20, 21, 22)
