Auto Density Control

Auto Density Control integrates three existing process components to provide automatic control of wet bulk density. It automatically measures product density and adjusts the process to maintain the desired density specifications.

  • Programmed to collect and analyze a sample as often as 45 seconds
  • Automatically adjusts the process to reach a new density setting in as little as 2 minutes
  • Decouple personnel from the product for greater food safety
  • Provide validation data for the process via the data display and recording capabilities of the system

Basic Components

Auto Density Control consists of three basic components:

  1. Source Technology’s sampling and bulk density measuring device (BDS)
  2. Wenger’s Automated Process Management (APM) system
  3. Wenger’s Back Pressure Valve (BPV) mounted on the end of the extruder to control specific mechanical energy input

Auto Density Control can be installed as part of a new system or retrofitted into a system that already has at least one of the basic components.
