When processing dense, free-flowing material like candy powder or granules, many manufacturers may be unaware of how a trickle valve can be a cost-effective replacement of a rotary valve that offers additional benefits. During the mixing and batching processes, some of the sugary powder may become airborne. This sweet particulate is captured by a dust collection system and emptied by a trickle valve where it can be reused or discarded. This type of valve consists of a simple rubber sleeve that requires no lubrication or power source, and has no controls or moving parts. In order to continuously dispense material properly, the trickle valve needs to have a vacuum present in the system. Unlike a rotary valve that has internal components that would be prone to excessive wear during candy production, a trickle valve reliably dispenses the dense material with very little maintenance or human interference required throughout its operational life. And best of all, you can purchase a trickle valve for a fraction of the cost of a rotary valve. To learn more about how a trickle valve works, view our free animated demo.
