Air curtains keep things flowing at WI dairy farm

摘要

Energy-saving mechanical systems are popping up everywhere - even cows are feeling the benefits. After decades of energy-saving applications for industrial openings and more recently for commercial building entrances such as hospitals, hotels and schools, air curtains now have been proven successful at preventing milking parlor equipment freeze-ups on dairy farms. Milk productivity setbacks were frequent challenges from November through March during subfreezing days for Griesen's Family Dairy located 60 miles northwest of Madison, WI, in Prairie du Sac, WI. The medium-sized, 680-cow farm suffered product losses and production delays from automatic milking equipment freeze-ups nearest the parlor entrances, and potential injury issues from slippery floors and poor indoor air comfort for employees.
