Résumé

Experimental studies for ice formation phenomena of water droplet fallen on a horizontal plate in a cold room have been performed. The ice formed in this method is so called ice stalagmite. Ethylene glycol aqueous solution of 2wt% is also tested for utilizing this ice formation phenomenon for freeze concentration. It is found that the shape of formed ice is affected by cold room temperature as well as by water-droplet heat. The ice shape is classified into four groups, column, spiral, cone and cave-in. A transparent ice, where solute is highly excluded, is obtained under the condition that the cone-shaped ice is formed. The 2wt% ethylene glycol aqueous solution is successfully concentrated to 17-30wt% in the present experimental range, which implies the possibility of utilization of the present method for freeze concentration.
