An open top tank is provided in which slush ice may be rapidly formed by a method forcibly projecting the formed slush ice from the tank or by a method retaining the slush ice within the tank for removal therefrom by other means. In addition, the tank may be used to cool liquid therein such as proplylene glycol down to -20 DEG F.-30 DEG F. degrees such that food stuffs may be dipped into the chilled propylene glycol for quick freezing of the food. The tank is portable and needs only a supply of liquid CO2 under pressure and propylene glycol (or water if slush ice is to be formed).
