What are steps 1-6 for direct and pellet extrusion

DIRECT: 1) raw ingredient 2) mix with water and heat 3) glass -> rubber then gelatinisation and melting 4) exit extruder and water nucleation 5) rapid expansion and boil off water 6) dry product PELLET: 1) raw ingredient 2) extrusion heating and gelatinisation 3) drying pellet becoming glassy 4) heating and expansion 5) pellet leaves fryer and cools down 6) solid glass brittle structure
