Higher hourly output → easier to cause uneven feeding, insufficient curing, loose pellet structure; Lower stable output → better starch gelatinization, tighter pellet texture, higher finished quality.
1. Pellet Hardness & Compactness
- Low output: Raw materials stay longer in pellet mill die hole, fully extruded, high hardness, not easy to break
- High output: Fast discharging, short extrusion time, loose internal structure, easy crack and powder return
2. Curing Degree & Digestibility
- Slow speed/low capacity: Steam fully penetrates materials, starch fully gelatinized, high digestibility for pigs
- Over high output: Short conditioning time, poor curing effect, feed nutrition not easy to absorb
3. Pellet Uniformity
- Matched rated output: Same particle size, smooth surface, consistent length
- Exceed designed hourly output: Uneven length, irregular diameter, mixed big & small pellets
4. Water Resistance & Storage Performance
- Standard stable output: Tight pellets, good water resistance, long shelf life
- Overload high output: Porous pellets, easy to absorb moisture, easy mildew in storage
5. Powder Rate
- Reasonable hourly yield: Low powder rate, high finished product rate
- Blindly increase output: More broken pellets, high powder content, waste raw materials
6. Service Life of Spare Parts
- Normal output: Ring die, roller wear slowly, stable pellet quality long-term
- Long-term high load output: Fast die wear, pellet quality drops rapidly in short time
Practical Production Rule
- Best quality state: Operate at 70%–85% of rated hourly output
- Max economic output: Not exceed 90% rated capacity
- Strictly forbid long-term full-load & overload operation, otherwise quality drops sharply
Simple English Version for Foreign Customers
- Lower reasonable output ensures better pellet hardness, smooth surface and low broken rate.
- Proper slow feeding improves steam conditioning effect, raise feed digestibility for swine.
- Excessive hourly output leads to soft pellets, uneven size, high powder rate and short storage time.
- Running machine under rated capacity can keep stable feed pellet quality and prolong machine service life.
- The most ideal working condition is 75%-85% standard hourly production capacity.
