Abstract

A double-sealing type apparatus for collecting spray freeze ice ball particles and a collecting method for the double-sealing type apparatus are provided. The double-sealing type apparatus includes a collector, a collecting trolley, a vacuum pumping device, a heating device, a first sealing pad and a second sealing pad. The collector is arranged on the collecting trolley, and is provided with a collecting port. The collecting port corresponds to a discharging port at the bottom of a freezing tower. A water inlet is further provided at the collecting port, and the water inlet is in communication with a space formed by the aligning of the collecting port and the discharging port. Good sealing performance is achieved in a double-sealing manner including the sealing pads and the ice sealing, so as to smoothly transfer ice balls in the freezing tower.
