Method to Produce Durable Pellets at Lower Energy Consumption Using High Moisture Corn Stover and a Corn Starch Binder in a Flat Die Pellet Mill

DOI: 10.3791/54092-v
What you'll learn
  • ✓ Operate a flat die pellet mill for biomass feedstock processing
  • ✓ Evaluate effects of starch binder and moisture on pellet durability
  • ✓ Measure specific energy consumption and pellet quality metrics
  • ✓ Apply high-moisture feedstock preparation techniques for pelleting
Protocol

Biopharma Insights In this study, a protocol was developed to produce good quality pellets using a flat die pellet mill at reduced specific energy consumption testing high-moisture corn stover and a starch based binder. The results indicated that adding a corn starch binder improved the pellet durability, reduced percent fines and decreased specific energy consumption.

Difficulty
intermediate
Total time
~4–6 hours per batch (including feedstock prep, pelleting run, and quality testing)

Steps

1
Prepare flat die pellet mill for operation

Set up and calibrate the flat die pellet mill to specifications. Ensure all components are clean and functioning before feedstock introduction.

2
Prepare high-moisture corn stover feedstock

Process and condition corn stover to target moisture content and particle size. Apply starch binder as specified and mix thoroughly for uniform distribution.

3
Execute high-moisture pelleting process

Feed prepared stover mixture into the pellet mill and operate at controlled parameters. Monitor output and collect pellets for subsequent analysis.

4
Measure pellet durability and energy consumption

Test pellet mechanical durability, percent fines content, and calculate specific energy consumption from mill energy data and pellet mass produced.

5
Analyze effects of binder and moisture on pellets

Compare pellet quality metrics across treatment groups varying in starch binder addition and feedstock moisture content. Document durability improvements and energy reductions.
