The invention provides a gas-liquid direct contact fluidized ice preparation system. The gas-liquid direct contact fluidized ice preparation system comprises a circulating refrigeration system and a fluidized ice preparation system body, wherein the circulating refrigeration system comprises a refrigeration compressor, a condenser and evaporators; the refrigeration compressor is connected with thecondenser; an outlet pipeline of the condenser is divided into two outlets, one is connected with the high-temperature evaporator, and the other is connected with the low-temperature evaporator; outlets of the high-temperature evaporator and the low-temperature evaporator are connected with the refrigeration compressor through confluence pipelines; the fluidized ice preparation system comprises an air duct, a fan, a nozzle and an ice storage bucket, one end of the air duct is connected with the top of the ice storage bucket, and the other end of the air duct communicates with an inner space at the upper portion of the ice storage bucket above a liquid level; and an ice water filter is arranged at the bottom of the ice storage bucket, the ice water filter is connected with a circulating pump, and the circulating pump is connected with the nozzle. By means of the gas-liquid direct contact fluidized ice preparation system, low-temperature ice-making cooling gas is obtained by the circulating refrigeration system; and the low-temperature ice-making cooling gas surrounds droplets or water mist, and rapidly cools to a freezing point to produce fine ice crystals, that is, the preparationof fluidized ice is completed.
