Just launched at Pack Expo International in Chicago is Fristam Pumps' next generation colloid mixer, featuring real-time gap adjustments, and hands-off clean-in-place (CIP). This new colloid mill features on-the-fly gap changes with an external gap adjustment lever, which can widen or shorten the gap to produce more or less shear without moving the inlet or outlet ports, or pausing the operation.
The new mixer's variable gap allows the user to dial in the particle size they need for shelf-stable emulsions, resulting in more consistent particle sizes with a tight distribution. Some applications for this mixer include mayonnaise, dressings, dips, oil and fat emulsions, condiments, dairy solids, and more.
"We have a blender, but blenders only go so far," says Jim McCoy, sales manager, Americas, Fristam Pumps. "We were getting a lot of requests saying, 'Hey, I need you to move down the particle size range.' So this is the result of that, and we can meet their exact, precise requirements for particle size. Plus, this mixer fits in with our whole portfolio of products."
The Fristam FCM also features CIP without disassembly, designed for hands-off use that allows you to adjust the gap to the maximum setting and CIP through the mill without removing any parts. The mixer has a max shear rate of 143,000 1/s, can handle sub-micron particle size, has a max inlet pressure of 250 psi, a max product flow rate of 50 GPM, a max CIP flow rate of 100 GPM, is bi-directional, and has a 50 HP motor size.
