Developed by PCRA and Central Food Technological Research Institute, Mysore
and patent filed.
The invention relates to an integrated hot air roasting machine for roasting/ toasting of cereals, pulses, spices, oil seeds and ready to-eat snac foods using flue gas, with the roasting, resting and cooling operations being performed in a single machine. The product processed by using this device has uniform roasting, uniform color, moisture and other sensorial properties. All the variables such as residence time, temperature of the hot air, resting time and cooling time of the roasted material are done sequentially by use of a programmable logical controller (PLC). The device is energy efficient as the hot air is recirculated. The roasted material will be discharged through the out let chute of the hot air roasting machine to the resting chamber, where the material is held inside this chamber for the moisture to stabilize.
