Abstract:
An ice slurry delivery system comprising:an ice slurry circulation loop to circulate ice slurry therethrough generally at a first rate;discharge means located along said circulation loop intermediate said inlet and outlet actuable to re-direct some of the ice slurry in said circulation loop to an end use at a second rate less than said first rate;an ice generating unit to generate fine particles of ice in an aqueous solution to create an aqueous ice slurry, said ice generating unit having an outlet connected to said circulation loop to deliver ice slurry thereto and having an inlet connected to the circulation loop to receive ice slurry from said circulation loop;a make-up inlet to deliver aqueous solution to said circulation loop when said discharge means is actuated to deliver ice slurry to said end use; anda flowmeter associated with said make-up inlet to detect delivery of aqueous solution to said circulation loop, said ice generating unit shutting off in response to a signal generated by said flowmeter when delivery of aqueous solution into said circulation loop via said make-up inlet is stopped.
