Solution Overview
Problem
Current airflow drying systems for refined cotton lack accurate moisture control, leading to inconsistent moisture content and revenue impacts due to either too low or too high moisture levels, which are not acceptable to customers.
Innovation Solution
A water drying control system incorporating a pressing machine, heat exchanger, infrared ray moisture transducers, and a control box with motorized valves and fans to monitor and adjust moisture levels by supplementing hot air and controlling the flow of refined cotton through the system, ensuring consistent moisture within the 6-8% range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If airflow drying mode is used without monitoring equipment, then the drying process is simple to operate, but the moisture content cannot be accurately controlled
Solution Approach 1:
The patent introduces infrared moisture transducers that continuously monitor moisture content in the drying process and feed this information back to the control system. This enables real-time adjustment of heating and airflow parameters to maintain precise moisture control throughout the drying process.
Solution Approach 2:
The patent replaces manual monitoring and adjustment methods with automated infrared sensing and electronic control systems. The infrared transducers optically detect moisture content without mechanical contact, and the control system automatically adjusts drying parameters based on sensor feedback.
2Manufacturing precision
If moisture content is reduced too low, then drying effectiveness is improved, but enterprise revenue decreases and customer acceptance is reduced
Solution Approach 1:
The control system uses real-time moisture monitoring to prevent over-drying by adjusting drying parameters when the optimal moisture range is approached, ensuring products meet customer specifications while maximizing drying efficiency and minimizing waste.
Solution Approach 2:
The system dynamically adjusts drying parameters such as temperature, airflow rate, and drying time based on real-time moisture content measurements, optimizing the drying process to achieve the precise moisture range required for customer acceptance and revenue maximization.
3Productivity
If moisture content is increased too high, then production speed is improved, but the refined cotton becomes unacceptable to customers
Solution Approach 1:
The infrared moisture transducers provide continuous feedback on moisture content, allowing the control system to accelerate drying when moisture is high and slow down or stop when the optimal range is reached, ensuring customer acceptance while maintaining high overall productivity.
Solution Approach 2:
The drying system operates dynamically by continuously adjusting drying intensity and duration based on real-time moisture measurements, rather than using fixed predetermined cycles, allowing optimization of both drying speed and final moisture quality.
