So how does Dry ice block work ?

At room temperature and pressure, dry ice directly sublimates into gas-CO2 without liquefication, absorbing a lot of heat and rapidly cooling the surrounding environment. Therefore, putting dry ice next to the object to be preserved can play a role in keeping cold and fresh. This is one of the most widely used fresh-keeping methods in the world. 

The amount of heat needed to sublimate 1KG dry ice into the same temperature of carbon dioxide gas-CO2 can reduce 137KG water temperature by 1℃.

In addition, dry ice can isolate oxygen-O2 by increasing the partial pressure of CO2 in the packaging, inhibit the breeding of bacteria, slow down their metabolism, and ensure that fruits, vegetables and seafood products are fresh and not spoiled.

Applications of dry ice blocks

Smoke Effect 

Dry ice is widely used in stage, theater, film and television, wedding, celebration, evening parties etc. to produce special effects.

Long and short distance transportation of electronic low temperature materials, precision components, etc.

Cryogenic refrigeration transport of plasma, vaccines and other medical materials that need special low temperature environment. During COVID-19 period , dry ice is widely used in international logistics .

Special Use — Air fertilizer 

The raw material of plant photosynthesis is inseparable from CO2, and the long-term supply of CO2 through volatilization of dry ice block can improve the efficiency of plant photosynthesis and increase production.

Practice shows that using this method can prolong the growth cycle of vegetables, increase the sugar content of crops by about 20%, reduce pesticide use by 60-70% . How usefull ! (PS: These datas come from https://www.sohu.com/a/475479226_120064990 , for reference only)
