Above carry is all about the prior beverage cooling device, except United States Patent (USP) the 2nd, 812, beyond No. 643, all make water as cooling body, water even frozen water do not have the function of very fast cooling, that is to say water can not be within three minutes the cooled beverage container, or the article (as being the food of on-beverage) that are placed in one of snap frozen as required.Most of design is for beverage being remained on suitable especially storage temperature, and between 4 ℃ to 10 ℃, and after the time through a segment length, beverage still keeps suitable temperature, and can take at any time always.

These existing cooling devices because water cooked cooling liquid, make its application be confined to the non-purposes of freezing, thereby are very restricted, that is, temperature need be equal to or higher than 0 ℃ or near 0 ℃, 0 ℃ of temperature of build-uping ice for water-setting.Even the water that is used in 0 ℃ must stir frozen water when making cooling liquid, freezes preventing.The ice that capacity is arranged if condense, whole freezing and cooling procedure all can stop, and correspondingly, most of refrigeration system all uses some reponse system device, when ice condenses, just closes freezing unit, so that recover the freeze cycle operation after allowing ice dissolve again.

Condense when 0 ℃ of F though salt-salt solution can be used to anti-sealing, salt-saline solution can stay smell, and stays residue on the article that are cooled, and simultaneously each used in freezing unit metal parts is had serious chemical corrosivity.

The existing apparatus neither one of relevant beverage cooling can provide the device of snap frozen on-beverage article in addition.

It is nonvolatile chemically inert cooling fluid under 25 ℃ of standard temperature and pressure (STP) that various unit neither one described here uses, and the metal parts to freezing unit does not have corrosivity again.
