Overview

This experimental setup system is used to determine the drying curve and drying rate curve of wet materials under constant drying conditions (i.e., constant hot air temperature, humidity, and flow rate, and constant contact between materials and airflow), and obtain the critical moisture content X0 of the material from the experimental curve. Within the range of the weighing sensor, wet felt, pulp board, wet sand, or other porous materials can be selected as measurement samples, and drying curve experiments can be conducted under different air volume or hot air temperature conditions, which can further be used for teaching or scientific research on the influencing factors of tunnel drying.
