The invention relates to a cold storage apparatus, comprising a barrel body, a barrel cover and a connecting ring arranged on the barrel body, wherein the connecting ring is composed of a handle witha button hole, a button head and a connecting rod with the button head and the button hole; and refrigerant is placed in the barrel body. The apparatus can be repeatedly used without consumption of fresh water; beverage bottles and beverage can be placed in an ice barrel without direct contact to the refrigerant; and the refrigerant are stored in the sealed apparatus. Due to no direct contact to air and difficulty to melt, the currently selected refrigerant freezes at the temperature from minus 10 to 18 DEG, has high cold capacity which doubles the cold capacity of ice cakes, long refrigerating time and good refrigerating effect, thereby being capable of replacing original ice cakes. In addition, the cold storage apparatus can be used with a household ice-cream machine in a matching manner, so as to ensure that the prepared ice cream has low temperature, fast preparation time, more sufficient crystallization and better mouthfeel. The apparatus has wide application range and flexible use, each apparatus is provided with the handle, and the apparatus can be moved by grasping the handle without the need of directly taking by hands, therefore, hands can not be frozen off, and the utilization is safe and reliable.
