This is a dryer in which moisture removal takes place by means of forced draft action created by hot air. The set-up consists of an insulated double wall chamber. Inside the chamber a tray is attached directly to a electronic weighing balance, which is fitted on the bottom, outside the chamber. Material for drying is placed in the tray and regular loss of weight is monitored. Air from a blower passes through a heating chamber and is used as drying agent. Arrangement is done to vary the airflow rate. The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Labview. This software is compatible to interfacing unit designed by Engineers. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.

    An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.
    The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Pain
