This document explains the recommended plant configuration for the implementation of the DRYCOM Moisture Control system using the Integrated Speed Control Module in the DRYCOM Moisture Meter.
Speed Control is an ideal and cost effective control solution for certain applications. If speed control is not appropriate a full energy control system must be used (using a separate DRYCOM Moisture Controller).
1. Speed Control can only be used in applications such as stand-alone dryers where adjustments in dryer speed or feed-in speed (or both) immediately change the dryer throughput
2. If the dryer is part of a continuous process (eg a wool scour) Dryer Speed Control will not usually be possible.
Streat Instruments will advise on the preferred control configuration after discussions with the client as to their requirements and process configuration.
As above for speed control to work, the kg/hr through the dryer must be controlled by the Speed Control output.
To do this either:
Wherever possible we recommend controlling the speed of both the feed hopper and dryer speed.
