<p>APPARATUS FOR AUTOMATICALLY MIXING AND CIRCULATING CLEANING SOLUTIONS THROUGH DAIRY EQUIPMENT Apparatus is disclosed for automatically mixing and circulating cleaning solutions through dairy equipment, such as in-place milk line equipment, bulk storage tanks, or the like. The apparatus comprises individual pumps for supplying ingredients, such as a detergent, an acid and a sanitizer, in a predetermined sequence to a mixing receptacle for mixing with a solvent such as water to form different types of cleaning solutions which are then circulated by a main pump through the equipment in a predetermined sequence. Control means, including a timer, are provided to fill the mixing receptacle with water and to operate the individual pumps and the main pump in a predetermined sequence to provide desired cycles of operation, such as first rinse (with water), wash (with detergent), second rinse (with acid), OFF, sanitize(with sanitizer), and OFF; The control means further includes electrical probe means for sensing the pH value of the cleaning solution to determine the amount of an ingredient being added by an individual pump during an appropriate cycle and for stopping that individual pump when the pH value reaches a predetermined Level thereby indicating that a predetermined amount of the ingredient has been added.</p> |
