Features
Designed to demonstrate operation Tray Dryer.
Real Time Data Acquisition System with graphical representation.
Comprehensive Instrumentation Panel with all necessary measuring instruments & Safety Devices.

Tesca Tray Dryer Unit is designed to demonstrate process of drying using Tray Dryer. The unit resembles the most commonly used industrial method of drying solids in bulk where hot air stream is passed over fixed trays of wet material. Students will able to vary the operating conditions and collect data to demonstrate both the theoretical and practical aspects of industrial drying practice.

A fan draws air in to the duct where it gets heated as it passes over the Heaters. This hot air then flows over the trays which hold the material to be dried. Measuring instruments record Air Temperature & humidity at different points, Air Flow etc.

Lab VIEW software provides real time data on computer
screen along with graphs & tabular results. Detailed Operation & Maintenance Manual is provided along with the trainer.
