The process of puffing corn balls mainly includes the following steps:
1. Raw material preparation
Select fresh corn kernels and grind them into a slurry, mix starch, water and other ingredients in proportion to form a dough with moderate consistency.
2. Puffing treatment
Feed the dough into a twin-screw puffing machine and extrude it under high temperature and pressure (120-140 ℃) for 3-5 minutes to instantly expand the corn.
3. Dry cooling
The expanded particles need to be dried and rapidly cooled to fix their shape and remove excess moisture.
4. Molding and Packaging
After drying and cooling, use molds to make spherical or other shapes, and finally seal and store them in an automatic packaging machine.
