Todays, the world food industry has undergone a great transformation. If in the past every city had the ability to produce and consume the products it needed, in today’s world this is not possible. It is natural for the food industry to become industrialized in a world where everything is moving towards industrialization. In the direction of industrialization, food transportation is one of the constant challenges of factories. Cooling units and refrigerated vehicles should be used in this regard. In this article, we address the challenges we facing toward perishable goods transportation and importance of the refrigerated transport. So join us.
Why use refrigerated vehicles?
Most food products produced in factories and farms are sensitive to overheating. Some of these products spoil at high temperatures and some lose their original quality. For example, if you store dairy or protein products at a high temperature, they will soon smell moldy. Or fruits and vegetables lose their original quality if you keep them in the sun or in a warm room.
Historically, there were several ways to protect food. From salt away meat products to storing vegetables and fruits in the basement and cooler spaces of the house. Today, however, science has come to the aid of human beings and has helped to solve this problem to a great extent. Refrigerators and freezers are doing well. There is no house or store that does not have at least one refrigerator.
This is, of course, only part of the story. The main problem in the industrial world is the transfer of products and foodstuffs from factories and agricultural lands and then their distribution. This is where refrigerated vehicles come into play. Today, a variety of refrigeration units are used to transport food. From large refrigerated trucks to small refrigerated vans. They all have one thing in common. and that is getting help from a refrigeration unit on the vehicle, whose job is provide transport container cooling.
How is food transported?
Now that we know the importance of using refrigerated vehicles, we can continue the discussion. In the following, we want to discuss how to transport food and its stages. In general, food products can be classified into several different categories. The first category is agricultural products. Some of these products enter the market immediately after harvest. But most of them are stored in the cold storage under certain environmental conditions, then they are marketed over time.
The second category are manufactured and processed products. These products are produced and processed in various factories, then marketed.
The above two things have one thing in common. That fix refrigerators should be used for long-term storage of food products. This is where the next issue comes in, how to transport food. When it is important to store food in certain temperature conditions, then it will be important to observe these temperature conditions during distribution.
There is another category according to the temperature and storage conditions of food. Some foods should be stored at sub-zero temperatures. For example, frozen meats and ice cream fall into this category. On the opposite side of these products are bunches that must be stored at temperatures above zero degrees Celsius. For this reason, two cooling units with different settings are used for food distribution.
Sub-Zero Cooling Units
Sub-zero refrigerated vehicles must be used to move the first batch of food products, i.e. frozen materials. In these units, the container temperature is always adjusted according to the type of product and usually below zero degrees Celsius. Sub-zero vehicles are also used to transport food over long distances.
Above Zero Cooling Units (A/C Units)
The second category of cooling units is the above- zero type. These vehicles are very suitable for transporting food in cities. In addition, they have better performance than sub-zero units for storing temperature sensitive materials.
Food distribution stages
Step 1: Loading at origin
Loading products is the first step in the food transportation system. First, a good refrigerator vehicle should be considered at this stage. Then check the condition of this vehicle for food transportation. Its cooling system is checked, the necessary standards are observed and then the products are loaded inside the vehicle.
Second stage: food transportation
This step requires more sensitivity than the other two steps. The driver of the refrigerated vehicle must comply with the prescribed protocols during transportation. He must constantly check the temperature and storage conditions of the products, and in case of problems, take certain measures. In case of any negligence at this stage, food products may have problems and lose their consumption.
Step 3: Food distribution
Food distribution is the last step in this system. At this stage, a series of standards and protocols must be observed. The distribution phase should be supervised by the driver of the refrigerated vehicle. Among the important points of this stage are preventing environmental pollutants from entering the container, maintaining the temperature and environmental conditions suitable for products and proper delivery.
Today, food transportation is done with the help of refrigerated vehicles. These vehicles are classified into two categories: sub-zero and above zero. They use sub-zero vehicles to transport frozen food. Above zero vehicles are also used to transport products such as fruits, vegetables, dairy products, etc. In general, the food distribution stages can be divided into three stages. The first step involves loading products from the factory door or refrigerator. The second stage will be the stage of transporting products, and the third stage is related to the distribution of products in stores and distribution centers; In all these three steps, a series of essential points must be observed and decisions must be made according to predetermined protocols.
