Effect of Extruder on the Weight of Corn

Effect of Pulverizing Machine Modulation Speed, Steam Pressure Temperature, Spiral, Mold Hole, Hot and Cold Discharge, etc. on Bulk Density

1. If the modulation speed is too fast, the residence time in the modulator is too short, the modulation is not enough, and the bulk density is easy to cause the bulk density to exceed the standard; if the modulation speed is too slow, the material stays in the modulator for too long, and the modulation is too long. Excessive puffing, puffed corn appears white, losing nutritional value.

2. If the steam pressure temperature is too high, the corn flour is over-expanded, the expanded corn appears white, and the nutritional value is lost; if the vapor pressure temperature is too low, the corn flour is not puffed enough, resulting in excessive powder and moisture content.

3. If the spiral pitch and the pore diameter of the die hole are too large, in the expansion, the pressure is insufficient to cause insufficient expansion, and the raw powder and moisture content are too high; if the spiral pitch and the pore diameter of the die are too small, the pressure is too high during the expansion, resulting in excessive expansion. Puffed corn appears white and loses its nutritional value.

4. If the puffed corn is cold-discharged, the moisture content will be lower; if the puffed corn is hot-discharged, it will easily lead to excessive moisture content.
