  • Patent number: 7363114
    Abstract: There is disclosed a system and method of formulating a batch comprising at least two chemicals. An embodiment is disclosed wherein a feedforward algorithm can be used to control the target blend. Subsequently a feedback closed loop control loop algorithm is provided for a multivariant blend. Use of this approach allows for a continuously autoreplenished and controlled blend. Also disclosed is the ability to control via feedforward and feedback algorithms a fast responding control mode that allows for the elimination of a container. This approach will allow for “one pass” blending with control. The controller implements an automated fault detection and correction system, thereby identifying necessary maintenance prior to failure. If failure does occur the signature recognition allows rapid analysis and correction thus maximizing tool availability.

  • Patent number: 7357563
    Abstract: Continuous stream ratio blending of two or more liquids. Each stream flow is time synchronized to all others and turned on and off to dose precise ratios into a constant pressure streams combining chamber. Combined on-off flows constitute a net flow rate exceeding some maximum continuous flow demand for the blended liquids. Dosed streams are pumped from the streams combining chamber at a rate matching their inflow, then through a mixing element into a finished blend tank. Use of a constant pressure streams combining chamber feeding a mix pump allows decoupling of individual streams ratio dosing flows and pressures one from another and from the combined stream. Blended liquid is available on demand as a continuous stream from the level controlled finished blend tank. The level sensor automatically starts and stops blended flow into the tank. Streams flow can be stopped upon completion of any dose cycle.

    Abstract: There is disclosed a system and method of formulating a batch comprising at least two ingredients. The ingredients are admitted to a container to partially fill it. The quantities of the ingredient in the container are determined, and a ratio of a target quantity to the determined current quantity for at least one ingredient is calculated. The next quantity of that ingredient to be admitted to the admixture is calculated by multiplying the target quantity by the calculated ratio to determine a corrected quantity. The corrected quantity of the ingredient is admitted to the admixture, and a quantity of another ingredient is admitted to the admixture to adjust the proportion of ingredients to the target formulation. These steps may be repeated until the batch is completed.

  • Patent number: 5727877
    Abstract: A main line for delivering a medical solution is connected at one end to a source of liquid. A secondary line is connected at two locations to the main line, bypassing a portion of the main line. A reservoir containing a particulate product is located in the secondary line. During a priming step, liquid is pumped to the reservoir in order to pressurize the reservoir and fill the reservoir to sufficiently immerse the particulate product. This priming step prevents the formation of agglomerates and preferential paths through particulate product. After the reservoir is primed, a fraction of liquid flowing through the main line is diverted into the reservoir and then routed back to the main line to introduce a solution of liquid and particulate product into the main line.

  • Patent number: 5537914
    Abstract: An apparatus is provided for improving quality and increasing syrup yield within a beverage blending system. The apparatus and the associated method are adaptable to existing proportioning and blending systems or the appropriate control and measurement equipment may be installed alone to provide a highly accurate control of the blend. This control is a function of the mass flow of at least one of the components input to the proportioner. From this mass flow determination an adjusted volumetric flow value for the component(s) is determined. The ratio of the volumetric flow of the water to the syrup is used to determine a signal to control the proportional blending. Adjustment of the blend ratio is made by comparing the calculated ratio to the set beverage values. Control of the carbonation of the system is also incorporated as well as a device to fully saturate the CO.sub.2 into the liquid flow.
