What is 3D Freezer?

3D Freezer®︎
[Rapid Refrigeration Rapid Freezing System]

Technology for rapid refrigeration yet maintaining the quality of the food

KOGA’s 3D Freezer®︎ rapidly freezes food by gently and uniformly enveloping it with cold air that maintains humidity so that almost none of the moisture in the food is lost, using our unique non-throughflow heat exchange method (ACVCS).

Structure and Principle of Operation of 3D Freezer®︎

Principle of operation of 3D Freezer®︎

Conventional air-blast type freezers simply refrigerated food by blowing cold, dry air onto the food at high speed. This resulted in food surfaces losing moisture. Koga Sangyo’s 3D Freezer®︎ uses a non-throughflow heat exchange method (ACVCS) that does not return wind to the fin coils so it is possible to maintain the moisture content of foods while

High-humidity cold air [3D cold air makes high-quality refrigeration possible

In slow freezing, the passing speed of the ice-crystal formation temperature range (0 to -5˚C) at which water turns into ice is slow, so the ice crystals become greatly distorted. This causes damage to the cells of the food, and is a cause of drips when the food is thawed. The Koga Sango 3D Freezer®︎ uniformly and rapidly refrigerates food to envelop it with high-humidity cold air [3D cold air], so the ice crystals are small and do not become distorted. Moreover, because the ice crystals are small, thawing is quicker.

Benefits of 3D Freezer®︎

Makes the impossible possible, and supports foods that were difficult to freeze before

Rapidly freezes yet maintains the food which was impossible to freeze until now, and its quality.

  • Fresh Fish
  • フFruit

Production and sales adjustment, expansion of commercial area

With fresh fish, the haul and the prices can fluctuate. With meat, the amount of the parts that can be sold fluctuates. Osechi ryori and the like have concentrated sales periods. This technology makes it possible to adjust the timing to produce, to sell, and to ship foods in a wide range of fields, while maintaining high-quality frozen storage. Moreover, this reduces food loss with frozen storage.

  • Osechi ryori
  • Christmas cake

Improves food safety

You can load high-temperature foods that have just been cooked or fried so it is possible rapidly to refrigerate these foods without pre-cooling or the risk of their being exposed to airborne or falling bacteria.

  • The beauty of the food is also preserved by rapid refrigeration.
  • The batter or other food coating is not blown away by the cold air.

Reduces loss caused by freezing

There is little loss after freezing when using the KOGA 3D Freezer®︎ because food moisture isn’t lost thanks to the high-humidity cold air. There is no need to increase the amount of raw materials to freeze food.

Reduces loss caused by freezing

Implements highly efficient operation while saving energy

The structure allows for little frost formation, so the number of times you need to defrost is lower, and that improves the efficiency of long-term operations compared to the conventional refrigeration systems. Reduces running costs approximately 30%. Note: Can change depending on the food refrigerated and frozen.

Ductless structure with excellent washability and hygiene

  • Ductless structure with excellent washability and hygiene
  • This uses a non-throughflow heat exchange method (ACVCS) so there is no cold-air recirculating duct inside the refrigerator. The entire system can easily be cleaned. There are no dead corners when cleaning, so there are no hotbeds for bacteria. This ensures high safety without the need to implement bacteria controls.
