초록 ▼

An accurate blending system for blending a feed liquid and first and second adjusting liquids includes a first feed means adapted to communicate with a supply of feed liquid, a second feed means adapted to communicate with a supply of the first adjusting liquid and a third feed means adapted to communicate with a supply of the second adjusting liquid. The first, second and third feed means may be pumps, valves or combinations thereof. A mixing device is in communication with the first, second and third feed means. First and second sensors are in communication with the mixing device. A controller communicates with the first and second sensors so that first and second characteristics of the solution in the mixing device can be detected. The controller also communicates with the first and second feed means so that delivery of first and second adjusting liquid to the mixing device can be controlled based upon the detected first and second characteristics of the solution in the mixing device.

The accurate blending system of claim 1 wherein the controller also communicates with the first feed means. 17. A method for blending a feed liquid and first and second adjusting liquid comprising the steps of: a) providing a recirculation loop mixing device;b) feeding a feed liquid to the recirculation loop mixing device;c) sensing a first characteristic of a solution in the recirculation loop mixing device;d) feeding a first adjusting liquid to the recirculation loop mixing device based on the sensed first characteristic of the solution in the recirculation loop mixing device;e) mixing the first adjusting liquid and feed liquid in the recirculation loop mixing device;f) sensing a second characteristic of the solution in the recirculation loop mixing device;g) feeding a second adjusting liquid to the recirculation loop mixing device based on the sensed second characteristic of the solution in the recirculation loop mixing device;h) mixing the first and second adjusting liquids and feed liquid in the recirculation loop mixing device to provide a mixed solution in the recirculation loop mixing device; andi) simultaneously detecting the first and second characteristics of the mixed solution so that delivery of the first and second adjusting liquids may occur simultaneously based on the detected first and second characteristics of the mixed solution. 18. The method for blending of claim 17 wherein steps e) and h) include pumping the solution in the mixing loop to perform the recirculation. 19. The method for blending of claim 17 wherein step b) includes pumping the feed liquid to the mixing device. 20. The method for blending of claim 17 wherein step d) includes pumping the first adjusting liquid to the mixing device. 21. The method for blending of claim 17 wherein step g) includes pumping the second adjusting liquid to the use device. 22. The method of blending of claim 17 wherein step c) includes sensing the conductivity of the solution. 23. The method of blending of claim 22 wherein step f) includes sensing the pH of the solution. 24. The method of blending of claim 23 wherein the feed liquid includes water. 25. The method of blending of claim 22 wherein step f) includes sensing the alcohol concentration of the solution. 26. The method of blending of claim 25 wherein the feed liquid includes water.
