Method and system for administering micro-ingredient feed additives to animal feed rations
View Patent ↗A system and method are provided for administering micro-ingredient feed additives or supplements to feed rations. The amount of each particular micro-ingredient to be delivered to a feed ration may be determined by a bulk density measurement. Alternatively, bulk density measurement may be used in combination with existing weight measurement and volumetric metering methods for multiple micro-ingredients. Delivery by bulk density requires determination of a bulk density value along with use of a dispensing device that dispenses a calculated amount of the micro-ingredient ration. The dispensing calculation may be achieved by analysis of delivery time, pulse count, or some other quantitative measure such as magnitude. Use of bulk density as a measurement technique eliminates the requirement for use of scales in the micro-ingredient delivery system.
1. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of:
determining a bulk density for at least one micro-ingredient;
assigning a base value to the bulk density;
dispensing the micro-ingredient from a dispensing device; recording the length of time in which the dispensing device operated to dispense the micro-ingredient;
calculating an amount of the micro-ingredient delivered taking into account the bulk density value and the length of time;
determining a compensation factor without weighing the micro-ingredient, said compensation factor being derived from consideration of at least one factor of a plurality of factors including temperature, viscosity, and loose/hard packed packaging and storage conditions;
adjusting the base value of the bulk density by the compensation factor; and
calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value and the length of time.
2. A method, as claimed in claim 1 , wherein:
said dispensing step is achieved by use of at least one of an auger and a pump.
3. A method, as claimed in claim 1 , further comprising the step of:
validating the bulk density value by comparing the calculated amount of the micro-ingredient dispensed to a weight of the micro-ingredient dispensed.
4. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of:
determining a bulk density for at least one micro-ingredient;
assigning a base value to the bulk density;
dispensing the micro-ingredient from a dispensing device;
recording dispensing of the micro-ingredient, said recording being a count of units;
calculating a revised amount of the micro-ingredient delivered taking into account the bulk density value and the recorded units; and
determining a compensation factor without weighing the micro-ingredient, said compensation factor being derived from a calculation of at least one factor of a plurality of factors including temperature, viscosity, and loose/hard packed packaging and storage conditions;
adjusting the base value of the bulk density by the compensation factor; and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value and the recorded units.
5. A method, as claimed in claim 4 , wherein:
said recorded units comprise pulse counts.
6. A method, as claimed in claim 4 , wherein:
said dispensing step is achieved by use of at least one of an auger and a pump.
7. A method, as claimed in claim 4 , wherein said recording step is achieved by use of at least one of a flow meter and a sensor.
8. A method, as claimed in claim 7 , wherein said sensor includes at least one of a capacitive sensor, an inductive sensor, and a laser sensor.
9. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of:
determining a bulk density for at least one micro-ingredient; assigning a base value to the bulk density;
dispensing the micro-ingredient from a dispensing device; recording dispensing of the micro-ingredient, said recording being a count of units;
calculating an amount of the micro-ingredient delivered taking into account the bulk density value and the recorded units; and
validating the adjusted bulk density value by comparing the calculated amount of the micro-ingredient dispensed to a volume of the micro-ingredient dispensed.
10. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of:
determining a bulk density for at least one micro-ingredient; assigning a base value to the bulk density;
dispensing the micro-ingredient from a dispensing device; sensing the micro-ingredient as it is dispensed;
calculating an amount of the micro-ingredient delivered taking into account the base value of the bulk density and a signal generated in response to the sensing step; and
determining a compensation factor without weighing the micro-ingredient, said compensation factor being derived from consideration of at least one factor of a plurality of factors including temperature, viscosity, and loose/hard packed packaging and storage conditions; adjusting the base value of the bulk density by the compensation factor; and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value.
11. A method, as claimed in claim 10 , wherein:
said sensing step incorporates a laser sensor to provide said signal, said signal being used to correlate a volume of the micro-ingredient to an amount of the micro-ingredient delivered.
12. A method of measuring micro-ingredients delivered to a feed ration, said method comprising:
determining a bulk density of at least one micro-ingredient; assigning a base value to the bulk density;
dispensing the micro-ingredient from a dispensing device; determining an amount of the micro-ingredient delivered taking into account the base bulk density value;
determining a compensation factor, said compensation factor being derived from a consideration of a boundary layer comprising at least two different micro-ingredients and without weighing the micro-ingredients;
adjusting the base bulk density value by the compensation factor;
and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value.
13. A method of measuring micro-ingredients delivered to a feed ration, said method comprising:
determining a bulk density of at least one micro-ingredient; assigning a base value to the bulk density;
dispensing the micro-ingredient from a dispensing device;
determining an amount of the micro-ingredient delivered taking into account of the bulk density value;
determining a compensation factor, said compensation being derived from a consideration of proportional amounts of at least two different liquid micro-ingredients and without weighing the micro-ingredients;
adjusting a base value of the bulk density by the compensation factor; and
calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value.
