  • Chemical delivery and on-site blending system for producing multiple products
    Patent number: 5833364
    Abstract: A chemical delivery and on-site blending system for producing multiple products is provided. Generally, chemical subcomponents are fed to a chemical blending system for making a multitude of products at the facility where the products are to be used. Also, a water line is connected to the system for blending with the subcomponents and for rinsing the system equipment. A microprocessor controls a series of inlet valves, a feed pump, and a mixer for formulating the products in a mixing tank. A flow meter monitored by the microprocessor measures the amounts of ingredients entering the tank. Once formulated, a product is discharged from the tank by a discharge pump also controlled by the microprocessor. Included with the system is a timed rinse cycle which rinses the tank after the product has been discharged.
