Dry ice cleaning is an environmentally friendly cleaning technology that uses dry ice (solid carbon dioxide) as a cleaning medium. The dry ice cleaning machine, also known as dry ice blasting machine accelerates the dry ice particles to hit the surface of the object through high-pressure airflow, and achieves efficient and non-destructive cleaning effects through the triple physical effects of low-temperature embrittlement, impact peeling and sublimation purge.

The principle of liquid nitrogen generator equipment is mainly based on air separation and cryogenic liquefaction technology, which uses physical methods to separate nitrogen from other gases in the air and cool it to liquid state.

Whether it is an industrial dry ice machine or a small dry ice maker, the core principle of dry ice making machine is that high-pressure carbon dioxide is cooled by rapid decompression to make part of the liquid carbon dioxide form solid dry ice. The following are the detailed steps and principles:

Dry ice cleaning technology, also known as dry ice blasting, is an industrial cleaning method that uses solid carbon dioxide (dry ice) pellets as the cleaning medium. Dry ice cleaning machine uses the thermal shock effect, mechanical impact force and expansion of carbon dioxide gas to remove dirt, grease, coatings, etc. by spraying dry ice pellets (particles) at high speed to the surface to be cleaned. Dry ice blasting machine is used in many industries due to its unique cleaning method and multiple advantages. The following are the advantages of dry ice cleaner:

There are three methods of liquid nitrogen quick freezing: liquid nitrogen immersion freezing, liquid nitrogen cold air circulation freezing and liquid nitrogen spray freezing.

The water electrolysis ozone generator uses a new PEM membrane with a low -voltage DC -drive solid -state electrode to remove ionic water. The water is separated from the hydroxide molecule in the form of proton exchange on the special anode solution interface. The solution interface is directly discharged. Oxygen molecules obtain energy on the anode interface due to the electronic stimulus generated by high -density current, and aggregate into ozone molecules.

How to make and produce dry ice? The production of dry ice is achieved by reducing the pressure of liquid CO2, causing 60% liquid CO2 evaporates and absorbs a large amount of heat to become gas, resulting in the rest 40% liquid CO2 reduces temperature to become snow-like solid, known as dry ice.

Ozone (O3) is a natural oxidant and bactericide, it is produced by ozone machines and there are two main types machine: electrolysis and corona discharge ozone generators.

A few days ago, one customer told me that his full automatic dry ice pelletizer produced less dry ice than its capacity. The machine is of high quality but less capacity. We believe that most customers have similar experience and we would like to simply explain as below.

With simple and professional words, we introduce dry ice properties, dry ice production and dry ice application in this short article.

Ozone (O3) is a relatively unstable gas that consists of three oxygen atoms. It will quickly degrade to pure oxygen and a free oxygen atom. This atom is extremely reactive, so ozone is a natural oxidant and bactericide, its sterilizing power in water is 300-600 times than chlorine.
