Structure of Dry Ice Blasting Machine

A dry ice blasting machine is an eco-friendly industrial cleaning machine that utilizes dry ice pellets as the cleaning medium, accelerating and spraying them via high-pressure compressed air to clean surfaces. Dry ice pellets are solid carbon dioxid produced by a dry ice maker machine, characterized by high density and an extremely low temperature of -78℃, which provides powerful cooling and freezing effects. Under normal temperature and pressure, dry ice sublimates directly from a solid to a gas without passing through the liquid phase, leaving behind no liquid residue or moisture.

The structure of a dry ice cleaning machine primarily consists of a dry ice feed system, a blasting system, and a control system:

1. Feed system: Comprises a cryogenic insulated hopper (to prevent premature sublimation of the dry ice) and a feeding mechanism (such as a rotary rotor), responsible for delivering dry ice pellets evenly and steadily to the blasting system.
2. Blasting system: Includes a dry ice spray gun, a nozzle, and connecting hoses; compressed air mixes with the dry ice pellets at the nozzle and accelerates them for discharge, with the nozzle shape influencing the blasting speedand cleaning coverage.
3. Control system: Features a PLC or touchscreen to adjust parameters such as blasting pressure, dry ice flow rate, and blasting distance, while also incorporating safety functions like fault alarms and automatic purging.

Compared to traditional cleaning equipment (such as chemical cleaner, high-pressure water washer, and sandblaster), dry ice blasting machine (like the Sichuan Aosituo industrial dry ice blaster machine) offers advantages such as high efficiency, zero pollution, and energy conservation, making dry ice cleaner an ideal choice for modern, eco-friendly cleaning. Dry ice cleaning machines are widely used for cleaning and decontamination tasks across various industrial sectors, including mold manufacturing, automotive production, electronics and semiconductors, aerospace, food and pharmaceuticals, and the electric power and chemical industries.
