■What is Tōmin?

“Tōmin” is a liquid freezing machine manufactured and sold by Technican. It freezes ingredients using a -30°C antifreeze solution. Liquid has approximately 20 times the thermal conductivity of gas, enabling freezing at an overwhelmingly fast speed. This prevents cell and tissue damage, preserving freshness and quality during freezing.
