Top Green Tech succeeded in developing with Japan a rapid liquid freezer that stores food at -70degree.

(examples of its usage): tuna, chub mackerel, halibut, garlic, and blueberry freezing, etc.
We are equipped with facilities to design and manufacture rapid and general freezers.

For rapid freezing, the degree in which the freezer freezes is not important. It depends on how fast it freezes which determines the quality of frozen food after thawing. The only method to freeze food at low cost, and also the quickest (within 30 minutes), is the ultra low temperature liquid freezing method.
