Kwa sababu barafu kavu inaweza kutumika kuweka chakula safi, barafu kavu imekuwa maarufu sana katika sekta ya chakula katika miaka ya hivi karibuni. Hata hivyo, kumekuwa na matukio ya barafu kavu kuumiza watu katika miaka ya hivi karibuni, ambayo imefanya wafanyabiashara wengi na watumiaji wasiwasi juu ya usalama wa barafu kavu.
The accident caused by dry ice
Mwananchi Bi Liu alinunua keki ya aiskrimu. Kulikuwa na icicles ndogo ndogo kwenye kifurushi. Bi. Liu aliiweka kwenye chupa ya maji yenye madini na kuiweka kwenye jokofu pamoja na keki. Baada ya muda kidogo, ghafla ilisikika kelele kubwa, na ikawa kwamba mlango wa jokofu lake ulikuwa umefunguliwa. Hapo ndipo alipogundua kwamba hizi icicles hazikuwa cubes za barafu za kawaida, lakini barafu kavu, kiasi kikubwa cha gesi iliyotolewa wakati wa mchakato wa usablimishaji wa barafu kavu. Barafu hii kavu ililipuka katika mazingira ya chupa ya plastiki isiyopitisha hewa.
Solve quality problems during dry ice production
How to solve the dry ice safety concerns? When producing dry ice for food, a high concentration of carbon dioxide must be used, which is a prerequisite for producing high-quality dry ice. However, there are harmful gases such as sulfur and benzene in carbon dioxide. Before making dry ice, purification is required to remove these impurities and achieve food-grade dry ice. Manufacturers must strictly control product quality and use high-quality raw materials and high-quality dry ice machines.
Increase market supervision
Baadhi ya makampuni feki ambayo hayajaidhinishwa na idara ya kiwanda pia yanazalisha barafu kavu, ubora wa barafu hizi kavu hauhakikishiwa, na kusababisha watumiaji kudanganywa na kuhatarisha afya za watumiaji. Kwa kuzingatia hali hii, idara husika zinahitaji kuongeza usimamizi na usimamizi wa soko la barafu kavu.
Enhance general knowledge of dry ice
Consumers and businesses who often use dry ice should learn more about some basic common sense. For example, dry ice must never be placed in a small airtight container, because the carbon dioxide generated when the dry ice sublimates cannot be discharged in time, and an explosion will occur. Also, dry ice should not be touched directly by hand. Because its temperature is extremely low, if you hold dry ice directly with your hands, it will cause damage to your skin instantly. You need to wear special gloves when you touch dry ice. A good way to store dry ice is to store the dry ice in a well-ventilated place, allowing the volatilized gas to be released naturally, or put it in a dry ice storage box.
