Dry ice is solidified CO2, its melting point is -78.5 ℃, and the surrounding temperature will be reduced to about 20 ℃ when it is volatilized. Therefore, it is easy to sublimate in daily storage, which causes dry ice to become smaller and cause losses. Therefore, a special dry ice storage box must be used for dry ice storage and transportation, which can effectively reduce the loss caused by the volatilization of dry ice.
What should be noticed when transporting with dry ice?
- If possible, it is recommended to store dry ice in an environment below -80 ° C and to store it with other items as little as possible. When using closed items such as dry ice storage boxes, leave a gap in the storage box. This is because dry ice is extremely volatile. If it is a closed environment, a large amount of CO2 generated by volatilization will be accumulated in the closed environment, which will cause the internal air pressure to rise continuously and there is a danger of explosion.
- Ili kuhifadhi barafu kavu, tumia sanduku maalum la kuhifadhi. Sanduku nzuri la kuhifadhi linaweza kupunguza upotezaji wa barafu kavu hadi 6 ‰. Ikiwa hakuna sanduku maalum, unaweza pia kutumia masanduku ya povu ya kawaida kuhifadhi barafu kavu. Ikiwa sio lazima, jaribu kukata kipande kizima cha barafu kavu kwenye vipande vidogo au granules. Hii ni kwa sababu barafu kavu iliyokatwa katika vipande vidogo itashuka kwa urahisi zaidi kuliko kipande kizima cha barafu kavu.
- Barafu kavu huvukiza haraka, haswa kutokana na joto la juu. Kwa hiyo, huwezi kuweka barafu kavu mahali pa joto la juu, na jaribu kuweka bidhaa za barafu kavu katika mazingira ya baridi na ya hewa. Hii ni salama na huruhusu barafu kavu kubaki kwenye jokofu kwa muda mrefu na isiyeyuke kwa urahisi.
- Usually, when we transport seafood, we need to put dry ice around the seafood so that the seafood stays fresh for a long time. When choosing dry ice, it is best to use block-shaped dry ice cubes. The dry ice cubes will keep the seafood longer cooling effect during transportation.
