A US baking ingredient processor producing milk of lime faced significant challenges with its existing 700-gallon (2,600-liter) mixing tank. Operators manually added calcium hydroxide powder into the open tank and relied on a top-entry agitator to form the suspension.
This process required workers to carry heavy 100 lb (45 kg) bags up a ladder and pour the fine powder from height — creating both ergonomic strain and airborne dust exposure risks. The company identified this method as unsuitable from a health and safety perspective and sought an improved solution that would protect operators while increasing production efficiency.
