Reducing the ripple effect

Every decorated product
has its challenges. Consider cereal, granola, nutrition and sports bars. Many
popular styles feature chocolate coatings on their bottoms and up their sides.
Topping and bottom systems do these jobs, and the chief problems they
must address are tailing and rippling.
“When a bar enters the coating bath, it can act like a snowplow,” said Neil
Anderson, director of business development, Axis Automation. That action
produces undesirable ripples in the coating.
Tailing occurs when excess coating is pulled along after the bar leaves
the coating bath. “Tailing wastes ingredients,” he noted. “And when tails
harden, they create problems at the wrapper during packaging.”
