Senior Editor Sharon Spielman tells you what you can expect to find in this issue of Process Cooling & Equipment.
One of my favorite movies is Willy Wonka & the Chocolate Factory. If you've seen it, you know that the greedy, gluttonous children meet some nasty fates, depending on their particular sin, while touring a bizarre chocolate wonderland. One impatient and spoiled little girl named Veruca Salt could not have known that tempering -- gradual heating and cooling of the chocolate -- is how the finest chocolate is made (and well worth the wait) or she would not have been such a hasty little thing.
When a production line in a chocolate factory needs to be readjusted to the myriad jobs that will run on it, time is precious (unlike most of the characters in the movie!). The more downtime there is between runs, the more profits there are that are lost. In this issue, read how the Toronto-based Cadbury plant reduced its changeover time from nearly 24 hours down to just a few and saved some serious change, too, by installing automated valves from Hansen Technologies Corp., Burr Ridge, Ill.
