Thus, MC is precisely and accurately sensed using two temperature sensors and software. In addition, the theoretically-based model provides a control algorithm that maintains the target MC with at least 30% less variation than that achieved using traditional MC sensing and control systems such as the non-theoretical Exhaust Temperature Control System that has no method for re-calculating the setpoint. Hundreds of successful Delta T applications have consistently validated Delta T technology.
Four additional SoftSensors have been derived from this technology and may be sensed and controlled using the same process variable (∆T) and control algorithm:
Product surface temperature
5% to 10% reduction in energy consumption
0.5% to 1% more water sold with product
Significant Production Increases
Eliminates over and under-dried product
3—6 months payback
Delta T MC control has been applied to a variety of products such as food, petfood, corn gluten, dried distillers grains (DDGS), biomass, textiles, non-wovens, carpet, lumber, coaters, chemicals, etc., while being dried using rotary, flash, spray, belt, fluidized-bed, tenter, tumble, impingement, and batch dryers. Adaptation of the Delta T to dryer and product is accomplished in 1 to 2 days.
