Extremely Low Temperatures and Your Blast Freezer

By | June 25, 2021

Simply put, a blast freezer, also known as shock freezers, are a type of refrigerator that is extremely cold. They can be used for various purposes, such as storing food or raw produce for a period of time. The concept of this kind of freezer storage is to quickly bring down the temperature of stored food or fresh produce, rapidly freezing them without any refrigeration cycles. This ensures that the stored food will stay fresh and tasty for a longer period of time.

To use a blast freezer, it is important to understand how they work. In this regard, you must know how they work, what causes them to work, and how they are classified according to the different models available in the market. Essentially, these appliances work on the basis of three factors: the freezer temperature, the air speed of heating, and the air speed of chilling. Understanding each of these factors can help you decide whether the model you are purchasing is the best one for you. On the other hand, it may also help you decide whether you need or want to purchase a model that is capable of combining both freezing and chilling functions. If you are wondering whether the appliance you are considering can meet your requirements, then continue reading further.

In order to understand how the blast freezer works, you must first understand what coils are for. Corners of the appliance are generally made of aluminum, which has the property of insulating heat. Thus, the stored food or raw materials inside these coils are kept from developing freezer burns or scalding. An additional feature of the corners is that some models have evaporator coils that are in the same unit as the coils. These coils are designed to lower the chill temperature of the stored food, while simultaneously maintaining the appropriate freezer temperatures.

Evaporator coils have also been found out to have benefits when it comes to extending the shelf life of various types of food. However, the good question now is whether or not the presence of the evaporator coils affects the effectiveness of the blast freezer. The answer to this question is: yes.

A freezer without a blower is called a dry freezer. It has no venting system and only a very small opening for the cooling of the water inside. This type of refrigerator is ideal for storing food that is not subjected to extreme conditions (freezing or heating). These models are often extremely small and can be placed in a cabinet. However, the freezer without a blower is generally referred to as a wet freezer because the water inside it is exposed to either freezing or heating conditions.

The air-flow design in a blower freezer is responsible for the efficient operation of the unit. This design ensures that hot air from the freezer is delivered directly to the defrost compartment. On the other hand, the absence of the blower prevents the hot air from going into the defrost compartment. The result is that some of the food may still be left in the original compartment when the freezer starts defrosting.

This means that the quantity of food being defrosted will depend on the rate of drying. If you want your defrosted foods to be extremely low in moisture, you will probably need to dehumidify the area around the blast room. This is usually done by installing a high quality blower. Humidity is extremely important because it controls the rate of evaporation. If the environment around the room contains extremely low temperatures, then the amount of water remaining in the space will also be very low.

An extremely low temperature environment causes damage to more than just the food in the freezer. The formation of crystals is also extremely important. Crystals can cause the structure of the appliance to warp or bend. While the cost of energy to run a normal freezer may be higher than a blast freezer, the cost of damage to the appliance would be considerably higher.
