Innovation for Dry Ice Cleaning System

Efficiency 30% UP – It’s a MIRACLE!!


Present shape of dry ice pellet is manufactured by circle. However, Kkalkkeumi makes matrix as injection module for producing square shape and the square pellet shows efficiency 30% higher. As the result of testing, on using present circle pellet, it costs $1.00 per 1 kg. But, in case of producing square shape, it costs $0.7 per 1 kg and is possible to get 30% cost reduction.


Through changing the pellet shape and preparing production system, the cleaning power by dry ice is improved and it has cost reduction effect. By this way, if signing a franchise agreement, competitive advantage is suggested to franchise members.
