Abstract

Cargill Industrial Starch (CIS) focuses on adding value to various starch fractionations through new market development. The purpose of this project is to identify the effect of different starch fractions on torrefied wood briquettes when blended at nominal 1% to 3% inclusion rates into torrefied red oak using the performance metrics of Kansas State Tumbling can durability and 24-hour moisture uptake. It was originally envisioned that conventional ring and die pelletizing could create testable 6.35 mm (¼ inch) pellets. However, after repeated failures and a multitude of die plugging issues, the decision was made to trial rotary briquetting as an alternative densification technique using a Komarek B220B briquetter. Previous batching trials conducted by the NRRI with the Komarek B220B using torrefied red oak as feedstock have yielded viable briquettes across a variety of binder types. Recent upgrades to the densification circuit have been made and include new grinding, larger batching and conveyance devices that enhance the safety and operational aspects of the system while allowing a variety of individual and unique densification equipment to be set in place and operated consistent with client needs across a variety of industries.
