ABSTRACT:
After a milking, the milking apparatus is cleaned in stages. First, the remaining milk is rinsed out with water. Second, the apparatus is washed through with detergent. The first stage rinse is very thorough, so that the second stage wash leaves the detergent solution still quite clean. The solution is stored in a separate tank between washes, and used again the next wash. Only a small make-up quantity of detergent need be added. Substantial savings in detergent discharges are achieved. The acid flush solution and the sanitizer flush solution also may be similarly stored for re-use. The detergent solution may be heated prior to re-use by heat from the milk.
