E.T. Oakes also keeps CIP considerations in mind when designing its mixers. “In the case of a batch mixer, we’ll supply spray balls inside the mixing tank, under the cover to aid in cleaning those tanks in place,” said Bob Peck, vice-president of engineering, E.T. Oakes Corp. Water pressure and high flowrates from a CIP system will cause the ball to rotate and spray the cleaning solution over a 360° cleaning area in a variety of patterns. The company also offers CIP pumps on their machines that go into CIP mode without wheeling in separate pumps.
