Refrigerated transportation is more special compared to dry van transportation. Perishable goods not only need to be refrigerated but also have different temperature requirements, We usually use refrigerated trailers for transportation of ice cream, chocolates, flowers, perishable goods, food products, cosmetics, and medicines.
Refrigerated multi-temperature trailers exist for a very large role, and the information that needs to be understood is below.
What is a multi-temperature trailer?
Multi-temperature trailers can realize multiple temperature zones in the interior, it can divide the interior of the compartment into 2-4 zones with different temperatures, and each of them has different temperatures, which can be ambient, refrigerated, frozen, insulated, etc. The temperature control of the refrigerated trailer is also installed to control the temperature of the refrigerated trailer. And installing the refrigerated trailer temperature control, as well as adjusting the refrigeration system, different temperatures can be realized.
Using multi-temperature refrigerated trucks, you can add more profit, compared to single-temperature refrigerated trucks, he can get more profit, load more goods, and more different kinds of goods.
Of course the competition of various temperature zones, you also need to take into account that some temperature zones can bring you more profit.
Temperature range of refrigerated trailers
The need for temperature in refrigerated trailers depends on the type of goods to be transported, if it is some fresh vegetables, his requirement for temperature is 0-3 ℃, if transporting fruits such as watermelon, apples, etc., the need for temperature is 7-10 ℃, if you need to transport these two products at the same time, you need to at least 2 temperature zones, and use the temperature system will be adjusted to the temperature for this zone.
Vegetables:
Carrots, carrots, white radishes, onions, mushrooms, domains. Need 0-2°C
Cucumbers, melons, watermelons, pumpkins, winter squash, tomatoes. Need 10 degrees Celsius
Meat:
Frozen beef, frozen eggs. Need -11 to -9.4°C
Fresh meat, pork. Needs a temperature of 0 to 1°C
Flowers:
Refrigerated transportation of flowers. 4°C to 18°C
Refrigerated transportation: below 0°C
Refrigerated transportation of medicines:
15 to +25°C (insulated)
-15 to -25°C
-60 to -80℃ (deep freezing)
Below -150℃ (ultra-low temperature freezing)
| Category | Products | Temperature Requirement |
| Vegetables | Carrots, white radishes, onions, mushrooms, leeks | 0-2°C |
| Cucumbers, melons, watermelons, pumpkins, winter squash, tomatoes | 10°C | |
| Meat | Frozen beef, frozen eggs | -11 to -9.4°C |
| Fresh meat, pork | 0 to 1°C | |
| Flowers | Refrigerated transportation of flowers | 4°C to 18°C |
| Refrigerated Transport | General refrigerated transportation | Below 0°C |
| Medicines | Insulated refrigerated transport | 15 to +25°C |
| Frozen medicines | -15 to -25°C | |
| Deep freezing medicines | -60 to -80°C | |
| Ultra-low temperature freezing | Below -150°C |
How to partition the multi-temperature trailer?
The temperature of a multi-temperature reefer trailer is generally front to back. The closer to the refrigeration equipment, the more excellent refrigeration effect will be obtained, usually close to the front part of the freezing zone, which can achieve the best refrigeration effect
Multi-temperature refrigerated trucks are divided into 4 zones
1 zone
Because it is close to the front of the vehicle, it has the best refrigeration effect.
It can be used for transportation of goods that require especially low temperature, such as pharmaceuticals.
2 zone
As the second compartment, it can be used as a freezer zone for the transportation of frozen meat and other products.
3 zone
Can be used as a refrigerated zone for the transportation of fresh meat, vegetables, etc. at temperatures between -1 and 7°C.
4 zone
Generally, the fourth zone is not set up for refrigeration, but because the refrigerated truck body is well insulated, it can have a very good thermal insulation effect.
Can also transport dry goods transportation. Used to transport products that do not require high temperatures.
The central partition partition (2 zones)
Generally speaking, the central partition is not divided into two zones, as mentioned earlier in the article, only needs to be divided into two zones. The reason for doing so is to take into account the refrigerated refrigeration system, which can save costs and increase the efficiency of refrigeration.
Benefits:
Cargo can be easily removed from the rear or side doors.
Of course, in addition to differentiating the multiple temperatures, there is also a need for uninterrupted temperature control to prevent accidents, which can cause irreparable damage if they occur.
Multi-temperature refrigeration system components
A good refrigeration system can realize more efficient transportation. We need to consider a variety of factors when selecting a refrigeration machine.
Condensing grid, controller, integrated telematics, composite door, compressor, stabilized current generator, evaporator.
