[0002] Dry ice is solid carbon dioxide. Dry ice has the functions of refrigeration, sterilization, cleaning or creating atmosphere. Dry ice is used in most industries in life. In the dry ice manufacturing industry, liquid carbon dioxide is usually introduced into the extrusion chamber inside the extrusion box. Part of the liquid carbon dioxide evaporates and absorbs heat, and the other part forms snowflake-shaped dry ice on the cavity wall due to the continuous decrease in the temperature in the cavity, and then is compressed to form block dry ice.

[0003] According to the application number 202320780658.3, a dry ice pellet making machine is disclosed, which comprises: a machine body, the upper surface of the machine body is fixedly connected to a fan, the outer surface of the fan is fixedly connected to a first air duct, one end of the first air duct is fixedly connected to a hydraulic oil tank, the upper surface of the machine body is fixedly connected to a mold barrel, and the upper end of the mold barrel is movably connected to a hydraulic cylinder.

[0004] The above scheme utilizes the suction force of the fan to absorb a large amount of cold gas generated by the sublimation of dry ice during the dry ice manufacturing process, so that the operator at the front end of the equipment has a clear view and is convenient for operation. However, the above scheme still has shortcomings in actual use. When a fan is used to collect the cold air generated by the sublimation of dry ice, the vaporization process of the dry ice is aggravated to a certain extent. The fan will generate airflow when running. This airflow will accelerate the air flow on the surface of the dry ice, thereby increasing the contact area and contact frequency between the dry ice and the surrounding air, resulting in most of the dry ice being vaporized.
