Abstract:
Method for continuous liquid stream digital blending comprising the following steps;providing two or more bulk supply sources of liquid products to be blended, providing a liquid flow meter downstream of each bulk supply source, providing a mixing chamber downstream of the liquid flow meters, providing a dose stream delivery assembly downstream of each liquid bulk supply for delivering small flow doses of liquid product from the associated bulk supply source through the flow meter to the mixing chamber, and providing a final blend container downstream of the mixing chamber;using the dose stream delivery assemblies to simultaneously deliver small doses of liquid product from each of the two or more bulk supply sources through each respective flow meter and into the mixing chamber, the start of flow and the end of flow of each dose or each dose stream delivery assembly being synchronized with the start and end of flow of all other dose stream assemblies;using the liquid flow meters to determine the quantity of each dose of liquid being delivered; andrepeating the foregoing steps a number of times to create a desired net flow rate of ratio blended liquid products from the mixing chamber into the final blend container.
