Development of household carbon dioxide generator from dry ice （J)

Abstract

Carbon dioxide is consumed as much as 1 million tons a year, but if carbon dioxide gas (carbon dioxide) that could not be used freely at home can be easily used, soda water (various juices, cocktails, beer) can be injected into drinking water. You can make wine, alcohol, etc.). Normally, weakly alkaline drinking water can be processed by gas injection to process the drinking water to an acidic maximum pH of about 3, which can contribute to securing healthy foods on the table. On the other hand, carbon dioxide gas spray has a large cooling effect, and spray on the skin in summer has a facial effect such as tightening the skin, so it is used for spraying lotion. Furthermore, it is also effective for cooling the inside of a helmet for harsh work under the scorching sun. These effects are applications that can be put into practical use by carbon dioxide gas that is safely and easily generated from inexpensive dry ice, and commercialization development is expected by applying the results of this research.
