SplitStream Keeps Cereal Flowing

The Problem

A producer of breakfast cereals approached Aerodyne about augmenting the dust collection system in one of their production facilities. This producer’s dust collection system pulled dust from sugar coating, conveyors, and ovens used for cooking cereal. Although they were using a wet scrubber to remove dust, recovering dust was difficult because of the wet scrubbers. Baghouses were not a viable alternative due to the temperature of the dust coming from the oven. They also faced rising operational costs from the water and power usage required for the large amounts of dust the system produced, plus the cost of wastewater disposal.

The Solution and Measurable Results

The producer sought Aerodyne’s S15000 SplitStream collector to ease the strain on their system, which is a great choice for easy removal and reuse of dust. In the SplitStream, dust is never trapped in a solid or liquid medium, something that baghouses and wet scrubbers rely on. The cyclone is also able to use a recycled airflow design for its secondary inflow, increasing efficiency and enabling collection from multiple sources without extensive ventilation modifications. By forcing the secondary stream into the collector, dust from that stream merges with the primary stream and avoids being abrasive or creating buildup that might result from sugars in the airflow.

They ultimately installed the SplitStream in front of their wet scrubber, lowering the volumes of liquid waste to be dealt with, and reducing strain throughout the system. At this time, the producer has 5 SplitStream collectors operating across the country at their various facilities.
