What is the difference between a quick freeze machine and rapid freezer, and a flash freeze machine and a flash freezer? Is it the same meaning?

A machine that quickly freezes food is called a quick freeze machine.

However, there are things that have the same meaning as a quick freeze machine but are called differently.

These are the similar names to the quick freeze machine: ` rapid freezer'', ``flash freeze machine'', and `` flash freezer''.

"Among the frequently asked questions from customers, do machines with different names have different specifications and uses?"

This question has been asked a lot, so I will explain it in this article.

What is the difference between a quick freeze machine, rapid freezer, flash freeze machine, and instant freezer?

There are many different names for rapidly freezing food, and there are many different names for freezers.

The machines we will compare this time are "rapid freezer", "quick freezing machine", "flash freezing machine", and "flash freezing machine".

In conclusion, you can think that machines with different names mean almost the same thing.

However, there are some differences, so I would like to introduce them to you.

We will take a deeper dive into each machine below.

What is a rapid freezer?

First, let me introduce you to the quick freeze machine.

Quick freezing machine and express freezing machine have almost exactly the same meaning.

A quick freeze machine is a machine that rapid freezing foods, etc., but its most distinctive feature is the freezing method that allows the food to pass through the ice crystal formation temperature range, which is the temperature range where moisture changes from water to ice, in a short period of time. Basically, a high-speed fan is used to cool the surface of the food to a low temperature.

Rapid freezers are especially used for ingredients such as seafood and meat.

Advantages of quick freezing machine

The advantages of quick freezing machines are as follows.

• Maintain freshness and quality
• Reduce risk of food poisoning
• Reduced cooking time

As the name suggests, a quick freeze machine is a machine that can quickly freeze food, so it can maintain freshness and quality.

In addition, by rapidly freezing food, it is possible to suppress the growth of bacteria and​ ​reduce the risk of food poisoning, which the food industry must be especially careful about.

Also, since it can be frozen quickly, cooking time can be drastically reduced.

Disadvantages of quick freezing machines

Below are the disadvantages of quick freezing machines.

• Installation costs are high
• Requires repairs and regular maintenance
• It is necessary to secure an installation location.

First, rapid freezer are expensive to install. Prices vary depending on the capacity and manufacturer of the refrigerator/freezer, but the average cost of a quick-freezer ranges from 50,000 yen to 200,000 yen. As you introduce and use the machine, there are cases where the machine itself breaks down, and when it breaks down, repair costs are incurred and the company's running costs increase. Also, if it breaks down, you will be unable to use it for at least a few days. If it becomes unusable, it could cause an opportunity loss for the company.

To prevent sudden breakdowns and lost opportunities, rapid freezer must be maintained regularly. By performing regular maintenance, you can use your deep freezer with peace of mind over the long term.

Also, a deep freezer is not a small machine.

When introducing a machine into a kitchen or factory, be sure to check the size of the machine and secure the actual installation location before installing it.

What is a flash freezer?

Next, we will introduce the flash freezing machine.

The names flash freezer and flash freezer have almost the same meaning.

A flash freezer is a freezing machine that cools food rapidly and completely prevents food deterioration due to freezing.

Advantages of flash freezing machine

The advantages of introducing a flash freezer are summarized below.

• Allows for more rapid cooling
• Can preserve nutrients without destroying them
• High energy saving effect

Flash freezers can freeze food faster than deep freezers. Conventional freezers take longer to cool down than current freezers, which results in the loss of vitamins and nutrients in food during freezing. Therefore, by using a flash freezer, it is now possible to preserve food for a long period of time while preserving its nutrients. It is also characterized by its high energy-saving effect as it can shorten the cooling time.

Disadvantages of flash freezing machine

• Installation costs are high
• There is a cap on capacity
• Only suitable foods

Flash freezers are similar to deep freezers and require installation costs. Running costs such as maintenance costs and repair costs will also be considered.

Flash freezers have a limited capacity. The more food you freeze at once, the longer it will take to freeze. Due to the long freezing time, the nutrients in the food cannot be preserved, creating issues with quality. Also, flash freezers are not suitable for all foods. For example, be careful with foods that contain water or are large in size, as they may take longer to freeze and the quality may deteriorate after freezing.

About the difference between a freezing machine and a freezing machine

There are two types of machines for freezing food: machines called freezers and machines called refrigerators.

Therefore, the question remains about the difference between a freezing machine and a freezing machine.

A machine that freezes food by rapidly lowering its temperature in a short period of time is generally called a "rapid freezer." However, the common name rapid freezer does not seem to be scientifically correct. The correct term is "deep freeze machine."​

Why is the correct name called refrigeration machine and not refrigeration machine?

A refrigerator is basically a heat source equipment that lowers the temperature in order to cool a space. Therefore, we do not refer to equipment that freezes the food itself. On the other hand, a freezer refers to equipment for freezing food, including a refrigerator (heat source equipment).

To summarize the above, the cooling equipment inside the freezer is called a freezer, so they are not the same machine.

About the difference between quick freezing machines (rapid freezer) and flash freezing machines (flash freezing machines)

From here, we will introduce the differences between quick freezers (rapid freezer) and flash freezers (flash freezers).

Many people think that "flash freezing machine" and "quick freezing machine" mean exactly the same thing.

"Flash freezer" and "quick freeze machine" are both machines that can freeze food quickly, so many people mistakenly think that they are exactly the same thing, but they are not the same and have some differences.

• different cooling speeds
• Different cooling methods
• Different freezing conditions

different cooling speeds

Quick freezers usually take several hours to cool food down to below -30°C, whereas flash freezers can freeze food more rapidly to below -40°C in about a few minutes to about tens of minutes..

Therefore, when comparing the cooling speeds, it seems that the flash freezer is slightly off to the right.

Different cooling methods

Quick freezers can freeze food in a short time by using refrigerant to freeze the food, whereas flash freezers use air to cool food more rapidly compared to quick freezers. or liquid.

Depending on the food to be cooled, you need to carefully consider whether a deep freeze or flash freezer is more suitable.

Different freezing conditions

Foods frozen in a deep freezer will form crystals, similar to traditional freezing methods. On the other hand, food frozen in a flash freezer freezes the water quickly, so no crystals form and the food can be frozen while preserving its cell structure.

Other than that, there is also a difference in the purpose of use. Quick freezers are often used for purposes such as long-term food preservation, but flash freezers can quickly cool food before cooking while preserving its freshness.

The above three points are the main differences between flash freezers and quick freezers. Both machines can quickly freeze food, but there are slight differences in cooling speed and cooling method.

How to make a quick freeze machine freeze more quickly

As introduced in "About the functional differences between quick freeze machines and flash freeze machines," there is also a difference in cooling speed between quick freeze machines and flash freeze machines, and flash freeze machines can freeze faster. can.

You can also freeze food more quickly with a deep freeze machine by following the three steps below.

• Expand the surface area of food
• Increase the temperature difference between room temperature and frozen temperature
• increase heat transfer coefficient

Expand the surface area of food

The trick to making a deep freeze machine freeze more quickly is to increase the surface area of the food being frozen. There is rapid freezer called a "brine freezer" that can freeze liquid by soaking it in food.

The more surface area the liquid can soak, the faster it will freeze.

Increase the temperature difference between room temperature and frozen temperature

By increasing the temperature difference between room temperature and freezing, food can be frozen more quickly.

rapid freezer has an ultra-low temperature liquefied gas freezing function. By using this function, you can create a large temperature difference between the room temperature and the inside of the refrigerator.

In addition, by using liquid nitrogen or liquefied carbon dioxide from a liquefied gas refrigerator, it is possible to create a temperature difference and achieve more rapid freezing.

increase heat transfer coefficient

The heat transfer coefficient is a value that represents the ease with which thermal energy can be transferred between two types of materials, such as a wall and air, or a wall and water. By increasing the heat transfer coefficient, the heat of the food moves faster and can be frozen in a shorter time.

To increase heat transfer, food is rapidly frozen by blowing air onto the food or by exposing the food to metal that has good heat transfer properties.

Conclusion

In this article, we introduced the differences between quick freeze machines, rapid freezer, flash freeze machines, and flash freezers.

I first introduced the conclusion, but although there may be some differences, each refrigerator has almost the same meaning.

We introduced "the difference between a freezing machine and a freezing machine" and "the difference between a quick freeze machine and a flash freeze machine".

The difference between a freezer and a freezer is in what the words refer to.

A refrigerator is a piece of equipment inside a freezer, and the entire machine used to cool food is called a freezer.

The main difference between deep freezers and flash freezers is the time it takes for food to freeze.A flash freezer cools food faster than a flash freezer.

We showed you how to freeze food quickly using a deep freeze machine. The methods introduced are ``increasing the surface area of food,'' ``increasing the temperature difference between room temperature and frozen,'' and ``increasing the heat transfer coefficient.''
