Open Type Freezer

Zen International Patents and Trademark

At supermarkets and convenience stores, we see ice displayed in a flat Freezer without glass doors in Japan. (See the photo below.)

ICE CREAM Section at a supermarket

Customers can easily select products when they are displayed in this open type freezer.
Even though the freezer has no glass doors, there is no need to worry about whether ice creams will melt.
The open type freezer is based on the principle that cold air is heavy and sinks downward. Cold air is blowing out constantly from the side of the upper part of freezer and it flows to ice creams to keep the temperature low. For this reason, ice creams does not melt.  Needless to say, technologies related to open type freezer have been patented.
