What is IQF freezing?

IQF (Individually Quick Frozen) is a method of preserving food that involves placing the product into a special container and then immersing it in liquid nitrogen. This process allows the food to remain fresh for much longer than if it were frozen using traditional methods.

The process of IQF freezing was developed in Japan over 30 years ago, but has only recently become popular in North America. There are many benefits to this type of preservation, including:

  • You can freeze large quantities of food at once
  •  Food remains fresh for much longer
  •  No need to thaw before eating
  •  Can be stored for months without losing quality

What are IQFs?

IQF stands for Individually Quick Frozen. This method of preserving food involves placing food into small containers that are then frozen. Once they have been frozen, they can be stored indefinitely without any loss of quality.

Why do we need IQFs?

The reason we use this method is because it allows us to preserve our food at its peak freshness. When we freeze foods in bulk, we lose some of their nutritional value due to exposure to air.

With IQFs, we are able to keep them completely sealed from the outside environment. They also allow us to store our food for much longer than if we were to just put it in a freezer.

How long does it take to freeze IQFs?

It takes anywhere between 2-4 hours to freeze IQFs depending on how many you have. If you want to make sure your IQFs don’t get too cold, you should place them in a container that has holes in it. These holes let out warm air but prevent cold air from entering.

How do people know if my product was IQF frozen?

There are several ways to determine whether or not your product was IQF frozen. One way is to look at the date code on the outside of the package. Another way is to check the inside of the package.

If the date code is still visible, then the product was not IQF frozen. However, if the date code is no longer visible, then the product may have been IQF frozen.

Benefits of IQF Freezing

There are many benefits to using the IQF method.One of the biggest advantages is that it can be used indoors without any type of ventilation. Another benefit is that the IQF method does not use much electricity. In fact, it only uses about 1/10th of the energy needed to run a standard HID lighting system.

Disadvantages of IQF Freezing

One disadvantage of the IQF method is that it takes longer to freeze than traditional methods. However, the time spent freezing is well worth it if you want to get the best results possible. If you’re looking for a fast-freeze method, look no further than the Suntory Method.


Machines are also used to process raw ingredients into finished products. There is a wide range of machines that can be used to accomplish this task.
