Differences between rapid freezer and traditional shock freezers

First of all, let's clarify the definition of "rapid freezer".

Broadly defined rapid freezer and rapid freezing are freezers that freeze food with cold air at temperatures as low as -30°C to -40°C in order to quickly pass through the maximum ice crystal formation temperature range of -1°C to -5°C. It generally refers to products called shock freezers/blast chillers. In some cases, ultra-low temperature refrigerated stockers in this temperature range are also called as such.

rapid freezer and rapid freezing in a narrow sense are devices that not only freeze in this temperature range, but also incorporate unique principles to achieve higher quality and ultra-fast freezing. Examples of unique principles include ``freezing by soaking in alcohol'' and ``freezing by blowing moist cold air in three dimensions.''
At our company, we call these "Special flash freezer ™" to distinguish them from shock freezers/blast chillers, which are rapid freezer in a broader sense.

The following are the main manufacturers of shock freezers/blast chillers, which are low-temperature commercial freezers.

• Hoshizaki
• Fukushima Galilei
• panasonic
• Irinox
• Koma Japan

What types of rapid freezer are there?

So, what types of "Special flash freezer ™", which is rapid freezer in a narrow sense, are available? The latest Special flash freezer ™ are mainly divided into two types.

Liquid freezing machine (liquid freezing type rapid freezer)

Instead of placing food in the low-temperature cold air inside the freezer, this type of rapid freezer freezes food by soaking it in liquid at -30°C to -40°C.
Can I freeze it by soaking it in liquid? You may have thought that, but liquids have higher thermal conductivity than gases and have the effect of removing heat many times faster, and rapid freezer that takes advantage of this effect is a liquid freezer. This is a very logical way of cooling.
Since we use a liquid with a negative temperature, we mainly use alcohol instead of water. The main body of the machine is not like a regular freezer, where you open the door and put food in it, but instead it has a tub-like liquid filled with liquid, and food is submerged in it and frozen.

Air blast freezing machine (air freezing type rapid freezer)

Air freezing type rapid freezer use the same low-temperature cold air inside the freezer as shock freezers, but they combine this with a unique principle to achieve even higher quality freezing.
Its unique principles include: ``irradiating electromagnetic waves to food,'' ``creating a magnetic field space inside the freezer,'' ``creating airflow inside the freezer and applying three-dimensional wind,'' and ``increasing thermal conductivity with high-humidity air.'' And so on.
This is a patented part of each manufacturer of rapid freezer, and exists as a unique product of that manufacturer.
Therefore, there will be differences in freezing speed and food quality depending on the manufacturer's rapid freezer.

Introducing 4 manufacturers of rapid freezer freezing liquid refrigerators

The principle of liquid freezing type rapid freezer is not patentable, and since they are relatively easy to manufacture, there are a relatively large number of rapid freezer manufacturers that sell them. Each company has a different design, size, price, and cost of the main unit, and some rapid freezer manufacturers have patented the liquid stirring function.

We will introduce some manufacturers of rapid freezer.

Saraya Co., Ltd.

Headquartered in Osaka, we are a major manufacturer of daily necessities that manufactures cleaning products, disinfectants, and other sanitary products with a 60-year history.
Since we originally handled alcohol, we also began planning and developing a liquid refrigerator that uses alcohol as a brine solution.
The product name of the liquid refrigerator is "Rapid Freezer".
We have models with a freezing capacity of 5kg, 10kg, and 20kg per hour.

Okui Electric Co., Ltd.

In this way, similar liquid refrigerators are available from several manufacturers. The amount of machines in circulation is relatively large, and in addition to new products, used products are also frequently available.

Introducing two manufacturers of air blast freezers (air freezing) rapid freezer

Next, regarding the manufacturer of air blast freezers among rapid freezer, this is rapid freezer manufacturer that combines low-temperature cold air freezers with their own "special principles" to achieve high-quality freezing. .

We will introduce some manufacturers with a rich track record.

Santetsu Giken Co., Ltd.

It was originally established as a 100% subsidiary of Mayatec Co., Ltd., a Kobe-based ship equipment company. Our strength lies in products that utilize electrostatic induction energy, and we have the unique "Depak System" technology.
This is an abbreviation for ``Dynamic Effect Powerful Antioxidation Keeping,'' and refers to a method of applying electrical energy to food using a high-voltage electrostatic induction generator developed independently.
The product name is ``Depak Air Rapid Freezer'' using this name.
In addition to low-temperature cold air of about -50℃, it gives electrical energy to ingredients and foods, activating water molecules and preventing the destruction of food cells.

We offer a wide range of lineups, from machines that can freeze 10 kg per hour to medium-sized and continuous large-sized machines.

rapid freezer and manufacturer do you recommend?

We have introduced several manufacturers of rapid freezer, but when deciding which manufacturer's product to choose, there are important points to consider, such as the quality of freezing, the price of the freezer itself, and the operability of the freezer itself.

Among them, the following two manufacturers are recommended by our company for liquid freezing type and air freezing type.

The recommended liquid freezing type is Yoneda Koki's Rejoice Freezer.

All liquid freezers from different manufacturers use the same principle of freezing food by immersing it in alcohol (ethanol), and all of their features are comparable.
So how do they differentiate themselves?These include the design and materials of the machine itself, the method of stirring the alcohol, and the functionality of the basket it is submerged in, and these differences in price also result.
Re-Joice Freezer are focused on functionality and price rather than appearance, and there are many inexpensive models, making them relatively easy to introduce compared to other liquid freezers.
We also manufacture other food-related equipment entirely in-house, so we can flexibly respond to even the most detailed requests from our customers.
This is the perfect product for customers who are not concerned with brand or appearance and simply want the effect of liquid freezing.

The recommended air freezing type is Daybreak's Artlock Freezer.
