15 March 2021 1 6K Report

I'm using corn grits with added 5% moisture, hydration for 1h before extrusion process.

The final parameters

Screw speed : 160

Feed rate: 50 r/m

Temperature profile: 40-80-120-165-175-175

Water pump rate: none

Max Pressure: 165pa

What modification needed to increase the pressure, and thus getting a more desirable extruded product ?

Faslu Rahman C.K.

I think an increase in moisture of premix can help to alter pressure-temperature parameters.
