METHOD FOR ACCURATELY MEASURING REAL-TIME DEW-POINT VALUE AND TOTAL MOISTURE CONTENT OF A MATERIAL

摘要

A system and method for accurately measuring the real-time valid dew-point value of a material and determining the total moisture content of the material within the valid dew-point value by using an algorithm during the material drying process. The algorithm estimates the valid dew-point value of the material and the total moisture content of the material by analyzing the sensor data received on a server. The algorithm determines a valid dew-point value by estimating an inflection point for the material, and the total moisture content of the material is determined within the valid dew-point value.

1. A method for accurately measuring the real-time valid dew-point value of a material within which the total moisture content of said material is determined, wherein said method comprises:
acquiring data from temperature and dew-point sensors positioned at dryer outlets; receiving the sensed data at a server after transmitting the acquired data by using programmable logic controller (PLC), relay, or wireless sensor networks; estimating initial moisture content of said material before the drying process begins; estimating moisture content of said material at any instant during the drying process; measuring a valid dew-point by determining an inflection point for said material; and determining the total moisture content of said material after determining said inflection point.
