Abstract

A system for mixing dairy animal teat dip from water and additives. The system includes a mixing manifold into which the water and additives are fed and mixed in a controlled manner. Mixed teat dip is automatically quality tested and monitored to provide data for controlling quantities of water and additives being fed to the manifold.

Claims

1. A method for mixing a dairy animal teat dip from water and a at least one additive in a mixing manifold, the method comprising the steps of:

regulating water flow from a local water source into the mixing manifold;

pumping a first additive into the mixing manifold;

metering the first additive to determine a quantity of the first dip additive pumped into the mixing manifold;

pumping a second additive into the mixing manifold;

to metering the second additive to determine a quantity of the second additive being pumped into the mixing manifold;

quality testing a substantially mixed teat dip flowing from the mixing manifold; and

collecting data corresponding to the quality testing of the mixed teat dip flowing from the mixing manifold, and storing the data in a controller.

2. The method of claim 1, and further comprising the step of:

adjusting the pumping of the first additive with the controller based on the quality testing data.

3. The method of claim 1, and further comprising the steps of:

monitoring ambient conditions at a dairy to generate ambient condition data; and

controlling the pumping of the first additive based at least in part on the ambient condition data.

4. The method of claim 1, and further comprising the steps of:

transmitting first additive quantity data to the controller;

transmitting second additive quantity data to the controller;

comparing in the controller, the first additive quantity data and the second additive quantity data to determine whether the additive quantity data meet predetermined specifications; and

controlling the pumping of the first additive and the pumping of the second additive if the additive quantity data do not meet the predetermined specifications.

5. A method of mixing dairy animal teat dip in a mixing manifold, the method comprising the steps of:

connecting the mixing manifold to a source of water that is near a point of use for teat dip;

obtaining a teat dip additive to be mixed with water;

at least partially filling a teat dip additive tank with a teat dip additive;

activating a water inlet valve with a controller to feed water to the mixing manifold;

metering the water with a water meter to determine a quantity of water being fed to the mixing manifold;

generating a water quantity signal corresponding to the quantity of water flowing to the mixing manifold;

transmitting the water quantity signal to the controller;

determining from the water quantity signal a corresponding quantity of additive to be mixed with water in the mixing manifold;

activating with the controller an additive pump to pump additive from the additive tank to the mixing manifold;

metering with an additive meter a quantity of additive being pumped to the mixing manifold;

generating an additive quantity data signal;

transmitting the additive quantity data signal to the controller for comparison to a predetermined additive quantity specification;

adjusting the additive pump to pump additive in a quantity that results in the additive quantity data signal substantially matching the additive quantity specification;

monitoring a mixed teat dip flowing from the mixing manifold and generating a corresponding teat dip quality signal;

transmitting the teat dip quality signal to the controller for comparison to a teat dip quality specification; and

adjusting the water valve or the additive pump if the teat dip quality signal does not meet the teat dip quality specification.

6. A system for mixing a substantially homogenous dairy animal teat dip from water and a teat dip additive, the system comprising:

a mixing manifold having a first inlet, a water inlet, and an outlet;

an additive conduit in fluid communication with the first inlet;

a first pump in fluid communication with the first additive conduit and the first inlet;

a first meter in fluid communication with the first additive conduit and the first inlet;

a water conduit in fluid communication with the water inlet;

a water valve in fluid communication with the water conduit and the water inlet;

a water meter in fluid communication with the water conduit and the water inlet;

a controller in communication with the first pump, the first meter, the water meter, and the water valve and to receive data from the first meter to operate the first pump and receive data from the water meter to operate the water valve to supply a predetermined quantity of the first additive and water to the mixing manifold; and

a quality sensor in communication with the mixing manifold outlet and the controller, wherein the quality sensor generates and transmits mixed teat dip quality data to the controller.

7. The system of claim 6, and further comprising:

a second additive conduit in fluid communication with a second inlet to the mixing manifold;

a second pump in fluid communication with the second additive conduit and the second inlet; and

a second meter in fluid communication with the second additive conduit and the second inlet; and

wherein the controller is in communication with the second pump and the second meter to operate the second pump.

8. The system of claim 6, wherein the controller adjusts operation of the pump and the water valve in response to quality data received from the quality sensor.

9. A system to produce teat dip at a distant location to a primary manufacturing location, the system comprising:

a local water supply connection;

at least one additive tank;

a mixing manifold that allows the substantially complete mixing of a teat dip to produce a ready to use teat dip; and

a quality sensor that measures at least one property of the substantially mixed, ready to use, teat dip after the teat dip exits the mixing manifold.

10. The system of claim 9, wherein the quality sensor determines a conductivity of the resulting ready to use teat dip.

11. The system of claim 10, wherein a conductivity reading that is out of a predetermined specification causes an alarm signal to be generated.
