Understanding the Two-Stage Dry Ice Briquetting Process: Why Pellets Come First
Commercial dry ice production favors a two-stage briquetting process because direct liquid CO2 pressing often causes trapped gas, fragile corners, and slow cycles. First, liquid CO2 becomes uniform pellets, then hydraulic pressing forms dense blocks. This improves density, extends shelf life, speeds production, and lets plants sell both pellets and blocks from the same supply.
