What is a Deep Freezer?

We all know what a deep freezer is and what it is for. It is that part of the refrigerator that is essentially for storing specific foods like dairy products, meat, etc., at a certain temperature.

A deep freezer has minimal fluctuations in temperature. As a result, you can store certain foods at a stable temperature. 

There is a temperature range that one should maintain inside the deep freezer. The level should not increase beyond -17 °C or 0 °F.

What Is The Difference Between Fridge Freezers & Deep Freezers?

Many people often mistake deep freezers for fridge freezers. However, both are entirely different. Although they have the same functionality, i.e., freezing the food, there is a huge difference between both the units. Let us learn about the significant characteristics that distinguish both the devices.


The primary thing we need to talk about when differentiating a fridge freezer from a deep freezer is freezing. What is freezing? It is a process that involves a gradual decrease in temperature. As a result, the device may take about 24 hours to freeze a food item. If the item contains water, it will get converted to larger crystals of ice. This is a prominent technique that most individuals use to keep their food frozen.

The main drawback of the freezing process is that it may cause the food to get dry and eventually damages it. The large crystals of ice may perforate the walls of the food items. As a result, the aroma and water content may escape the food.

Deep Freezing

Unlike freezing, deep freezing is a process that involves a rapid decrease in temperature. This technique allows the food to freeze completely at extremely low temperatures. The time taken for this process is from a few minutes to less than an hour. 

This is how the deep-freezing technique works. When you expose the food to extremely low temperatures, i.e., -30 to -50oC, it allows the product’s temperature to reach a level as low as -18 degrees C. Consequently, the water content in the food crystallizes completely. This further limits the proliferation of microorganisms and the killing of cells. When you freeze the products by this technique, it will help them to retain their freshness and flavour.

Frequently Asked Questions

1. How cold should a freezer be?

Many are not aware of the ideal temperature that a freezer should have. The temperature range that a freezer should have is dependent on the model and the specifications provided by the manufacturer. On average, it should be zero degrees Fahrenheit or lower. This is because it helps to maintain and preserve the frozen foods and prevents them from decay and spoilage. It is essential to check the freezer with a dedicated thermometer at least weekly once. It ensures whether the unit is properly or not.  

2. Can a freezer be too full?

It is advisable not to overcrowd the freezer. When you dump the freezer with items, they may prevent the cool air from circulating across the device. As a result, the interior of the freezer may not be as cool as it needs to be. It blocks the vents, obstructs the airflow inside, and further causes the food to defrost in spots. This eventually puts pressure on the condenser, making it also overwork. Ultimately, it contributes to the increased power consumption and electricity bills. 

3. Can freezer food go bad?

Food kept in the freezer never gets bad. However, you need to maintain the right temperature inside. When you are storing food for a long period, it is susceptible to freezer burn. Maintaining a consistent temperature inside the freezer is crucial. Any fluctuations in the temperature may cause harmful bacteria to grow, spoiling the food. Other temperature issues that may cause the frozen food to get spoiled are the inadequate quantity of food items leaving the door open for a long time. This lets the food defrost and spoils it. This defrost problem may frequently occur when the door seal of the freezer or any other part of the unit fails. Whenever there is a power outage, a fully overloaded freezer or an unopened freezer can help in maintaining the right temperature inside for up to 48 hours.

4. What is the difference between a freezer and a deep freezer?

A freezer is located in the upper portion of a fridge and is small in size with a capacity of 150 liters. On the other hand, deep freezers are large boxes that come in various sizes and open horizontally. They have a capacity of up to 500 liters.

5. What is a deep freezer used for?

A deep freezer is used to store meat and other food in larger quantities. Additionally, it is used to store medicines and blood samples as it can maintain a specific temperature range.

6. What is the temperature of a deep freezer?

A deep freezer maintains a consistent temperature of -30 °C to -50 °C. At that temperature level, the temperature of the stored food items reduces to -18 °C within an hour.

7. How long can meat be frozen in a deep freezer?

A deep freezer allows you to keep the meat frozen for up to 12 months based upon the specific meat variety.

8. Is a chest freezer the same as a deep freezer?

The chest freezer is a type of deep freezer that is very large and has a box or chest-like appearance. It is covered with hinged lids that are opened in the upwards direction. They are very cheap and can be used to store large quantities of meat and food.
