Spray Dryer Closed-Loop Control

The BatcHHouse Density Meter is installed below a spray
dryer to provide an in-line, real-time dynamic bulk density
output signal.

The output signal is used as feedback to the spray dryer
controls which then is used to control bulk density, achieve
desired particle size, or enhance material flowability.

Dryer Control

Density feed forward to optimize drying time and
reduce cost.

Extruder Feedback

Density feedback to extruder/feed system to
control quality of product.

Blend Dissimilar Density Materials
to a Controlled Target Density

In-line BatcHHouse Density Meters measure dynamic bulk
density of two streams of bulk solid materials.

The operator enters the target density and line setpoint into the
controller. Each belt feeder receives a setpoint to ensure the
packaging line receives material at the proper dynamic bulk
density and line setpoint.
