A method of producing calcium chloride granules of a specific size from a calcium chloride and water solution in a completely closed environment by controlling the rate of fall of a specific size of solution droplet through an up-current of hot, dry gas.
Claims3
A process of producing calcium chloride granules from a solution of calcium chloride and water comprising;
- a. introducing droplets of calcium chloride and water solution into an enclosed chamber, said chamber having an upper and lower portion, said droplets being introduced into said upper chamber;
- b. introducing a current of hot, dry gas into said chamber, said current of hot, dry gas flowing from said lower portion of said chamber to said upper portion of said chamber;
- c. adjusting the flow of said current of hot, dry gas so as to suspend said droplets in said current of hot, dry gas at a controlled rate of fall for sufficient time so as to remove said water from said droplets through evaporation, said calcium chloride within said droplets thereby forming said granules;
- and
- d. removing said granules from said chamber without opening said chamber.
