[Latest version] Understand in 5 minutes! "Types of rapid freezer" How to find the best rapid freezer

“I’m interested in rapid freezer, but I don’t know what types there are.”
“What criteria should I use when choosing rapid freezer?”

Do you have any of these problems?

There is not just one type of rapid freezer, but there are many different types of machines. In addition, there are various sizes, such as small rapid freezer that can be installed compactly to save space, and large rapid freezer that can be mass-produced.
Each machine has different features and prices, so selecting a machine is important when introducing one.

So, this time, we will explain the types of refrigerators.
We will also share four points that will be helpful when deciding on rapid freezer, so please take a look.

What is rapid freezer?

A brief explanation of rapid freezer is given below.

First of all, rapid freezing is a freezing method that allows food to pass through the temperature range of -5°C to -1°C (this is called the maximum ice crystal formation zone) within 30 minutes, where the water in the food easily freezes.

When food is frozen over time using conventional freezing methods, large ice crystals are formed as the water in the food turns into ice. These large ice crystals destroy cells. When this is thawed, drips flow out from the destroyed cells, and moisture, flavor components, and nutrients are lost. As a result, food quality deteriorates.

Therefore, by using rapid freezing technology, the ice crystals in cells are frozen in a small, dispersed state. This prevents food cells from being destroyed and allows food to be stored frozen without degrading its quality.

A machine that can perform this rapid freezing is called rapid freezer.

Types of rapid freezer

There are four types of rapid freezer: air blast freezers, liquid rapid freezer, liquid nitrogen freezers, and special method types.

air blast refrigerator

An air blast freezer is a device that freezes food using cold air, similar to a regular household freezer. The difference from regular freezers is that air blast freezers use cold air at approximately -30°C to -40°C.
Among them, we especially recommend rapid freezer called Artlock Freezer.

The reasons why we recommend Art Lock Freezer are as follows.

・Minimize damage to ingredients and freeze them to the highest quality
・You can freeze freshly cooked food as is
・The quality of any food ingredient is stable regardless of when or how it is frozen.
- Air is blown evenly over the entire surface, allowing for even freezing.
・No need to defrost the cooler

liquid quick freeze machine

A liquid rapid freezer is a type of rapid freezer that freezes food by immersing it in an antifreeze solution such as alcohol that has been chilled to -35°C.

Among the liquid rapid freezer, the one we recommend is Re-Joice Freezer.
Re-Joice Freezer is a machine that freezes food by immersing it directly into a bath of alcohol cooled to -35°C.

Here are some reasons why we recommend Re-Joice Freezer:

・Liquids have approximately 20 times higher thermal conductivity* than air, and freeze at an astonishingly fast rate.
・As the liquid hits the food evenly, uneven freezing does not occur.
・Can be custom-made to suit the customer's size and purpose
*Thermal conductivity is a value that indicates the ease with which heat is transferred through a substance.

liquid nitrogen cooler

A liquid nitrogen freezer can instantly freeze food by spraying liquid nitrogen gas at -196°C onto the food.
This is an effective freezing method when freezing large quantities of food.
However, using liquid nitrogen requires more running costs than air or liquid freezing, and care must be taken when handling it.

Special method type

There are other types of freezers that do not fit into the three types of rapid freezer listed above.
We will introduce it here under the name ``special method type.''
Special type refrigerators freeze food by applying forces such as magnetic flux, electromagnetic waves, and vibrations to the freezing environment. Using this mechanism, the ice crystals that form inside the cells of the food are suppressed from growing. As a result, food can be stored frozen while maintaining its quality without destroying the cells.

This time, we will introduce four types of rapid freezer, and if you choose the right one, you will be able to achieve great cost-effectiveness.

Now, I would like to tell you four points to consider when choosing rapid freezer.

How to choose rapid freezer- 4 points -

There are several points to consider when choosing rapid freezer. This time, I would like to introduce four particularly important points.
When considering rapid freezer, please refer to the points we will introduce below.

1.Quality

The first thing to consider is how much quality you want to provide.
The performance of rapid freezer ranges from perfect to perfect, and it greatly affects the quality of food when thawed. In order to maintain the same quality after thawing as before thawing, it is essential to choose a high-quality rapid freezer.
Also, rapid freezer you should choose will depend on the ingredients.
You need to be clear about the level of quality you want to provide, such as wanting people to enjoy the taste of the ingredients and the taste of freshly made products, and wanting to produce in large quantities even if the quality deteriorates a little.

2.Cost effectiveness of rapid freezer

Some people who are considering rapid freezer have the impression that "rapid freezer = expensive." It's certainly not a cheap purchase. However, if used correctly, it can have great benefits. This also makes it easier to achieve cost efficiency.

Specifically, rapid freezer have the following advantages:

・Maintains high quality ingredients
・Able to provide seasonal items for a long period of time
・By freezing food in advance, you can reduce preparation work before opening and improve efficiency.
・Reduction of waste loss and transportation costs

Of course, there are many benefits to using rapid freezer, but you need to be careful when installing rapid freezer.
It is also true that the cheaper the price, the lower the quality of the food when thawed.

Due to budget constraints, some people buy cheap rapid freezer or second-hand products, but if used properly, rapid freezer can last more than 10 years. Therefore, when installing rapid freezer, it is very important to keep in mind the long-term use of rapid freezer.

Some people look at the price of rapid freezer and think they are expensive.

Therefore, this time we will introduce an example of how rapid freezer can be cost-effective.

Let's say you have installed rapid freezer that costs about 3.5 million yen each. Even if the number of operating days per month is 20 and it is used for 5 years, it can be introduced for about 3,000 yen per day.
*Most companies have been using rapid freezer for over 10 years.

rapid freezer can be installed for about 3,000 yen per day, but if you can get a cost-effectiveness of 3,000 yen per day, you will be able to get your money's worth.

In order to actually achieve cost effectiveness of 3,000 yen...
① Before introduction: All unsold products were discarded.
After introduction: Effective use of 1,000 yen worth of waste through rapid freezing
② Before introduction: Part-time workers were preparing from early hours before the store opened every day.
After introduction: By using rapid freezing to prepare food in advance, the preparation time for part-time jobs was shortened and labor costs were reduced by 2,000 yen/day.

⇒This is all you need to pay for rapid freezer!

When choosing rapid freezer, keep in mind that you will be using rapid freezer for a long time, and choose a machine with cost-effectiveness in mind!

3. Convenience of rapid freezer

If rapid freezer is used infrequently, you will not be able to recover the cost even if you install a highly cost-effective rapid freezer.
Also, the more time it takes to freeze food, the less efficient it will be. There is a big difference in production between operating the machine only a few times a day and running it dozens of times a day.
In order to improve work efficiency on-site, a very important point of view is whether it is easy to use on-site. Therefore, it is necessary to choose a machine from the perspective of those who use rapid freezer on-site (factories, stores, etc.) and are involved in the work.

4.Aftercare

If you don't have support in the unlikely event that rapid freezer you installed breaks down, sales will be affected during the period when it is not operational, and repairs will be costly.

Another important point when choosing rapid freezer is to purchase from a company that has a good support system, such as teaching you important points when using it and providing assistance in the event of a breakdown.

Conclusion

What did you think?
There were four types of rapid freezer: air blast freezers, liquid rapid freezer, liquid nitrogen freezers, and special method types.

Additionally, the features and prices vary greatly depending on the machine.

When purchasing rapid freezer,

・What level of quality do you want? (Quality)
・Is the performance cost-effective (cost-effectiveness)?
・Is it rapid freezer that is easier to use on site (convenience)?
・Response in case of failure (after-sales support)

It is important to select rapid freezer with the above four points in mind and with long-term use in mind.
By doing so, you can obtain higher cost-effectiveness than the price of the machine.
When installing, please choose the most suitable rapid freezer for you.
