Experimental studies for freezing of liquid droplet fallen on a horizontal plate located in a cold room have been performed. The ice formed in this method is so called an ice stalagmite. Effect of height of the fallen droplet on the ice formation pattern has been examined using water droplet. As for the application of the present ice formation method to freeze concentration, 2, 5 and 10wt% ethylene glycol aqueous solutions have been frozen to examine the effect of concentration of the droplet on freeze concentration characteristics. It is found that the present freeze concentration method using ice stalagmite takes advantage for low concentration liquids.
