IQ 01.5 – Convection Drainer

The objective of the IQ 01.5 equipment is to analyze the drying by convection of the element to be studied, modifying the environment in which it is and reflect the data of the changes produced.


This process is widely used in the food industry, and can be viewed and studied very easily. By means of the control knobs, the air velocity and the heating power can be varied, so that we can study the phenomenon of drying in different operating regimes.

The transparent register allows to visualize the solid to be dried during the process, while a precision electronic balance indicates the produced mass variation.

The temperature, humidity and air velocity sensors indicate the parameters of the process, which allows the student to perform different practices.

The complete practical manual, shows the practices to be developed by the students, along with the data log tables, on which the student will work with the data obtained in the practice. The practical notebook is delivered with a version of the teacher, which shows the data of the practices already resolved.
