Customized Reefer Truck Boxes: Keep Meat Fresh All the Way

Meat products are common ingredients in our daily lives, and almost all delicacies are inseparable from meat. As people’s requirements for health and nutritional value become higher and higher, the transportation process of meat products must meet strict food safety standards.

For frozen meat, its storage temperature should be controlled between -18℃ and -22℃. Meat food can be prevented from oxidizing below -18℃, while the freezing time can be extended exponentially in the low temperature environment below -23℃. Meat reefer truck can slow down the decomposition of enzymes in meat, delay the oxidation process, and inhibit the growth and reproduction of microorganisms, thus maximizing the freshness of meat food.

Low temperature can inhibit the growth and reproduction of microorganisms (bacteria) and enzyme activity. The main microorganisms on fresh meat include: psychrophilic bacteria, mesophilic bacteria, thermophilic bacteria, salmonella, staphylococci, etc. Here is a reference table of suitable temperature ranges for microorganisms:

• The minimum growth temperature of psychrophilic bacteria is 0℃-5℃, the suitable growth temperature is 12℃~18℃, and the maximum temperature is: 20℃;
• The minimum growth temperature of mesophilic bacteria is 10℃, the suitable growth temperature is 30℃~40℃, and the maximum temperature is: 45℃;
• The minimum growth temperature of thermophilic bacteria is 40℃, the suitable growth temperature is 55℃~65℃, and the maximum temperature is: >80℃;

Relative to frozen meat, cold meat in the taste and nutritional value is undoubtedly better. But for the refrigerated truck box insulation requirements are higher, the requirement to use the cold chain logistics system to ensure that the meat in the processing, storage, transportation, sales until the cooking of the whole process is always in the 0 ℃ -4 ℃ ice temperature environment, if the middle of which is not good control, it will mean that the cold chain is interrupted.

How Should Cold Meat Be Transported?

White meat in the transportation, it is necessary to use refrigerated trucks for distribution, generally in the refrigerated compartments on top of the addition of meat hook groove and meat hooks called meat hooks refrigerated trucks, is specialized in the transportation of cold meat of a refrigerated truck, which can ensure that fresh meat in the process of transportation does not deteriorate, the white meat hanging transportation and can ensure that the white meat ventilation and heat dissipation, is not extruded, and the appearance of the non-damaged.

White meat should not be transported in open vehicles, and any substandard vehicles found to be transporting it will be penalized by the relevant authorities.

Cold meat needs to undergo a qualified inspection before being able to transport, and must have a quarantine certificate, refrigeration inspection, health license, meat inspection certificate. If one of them does not meet the standard, then it will also be dealt with by the relevant departments on the spot, light destruction, serious will be detained.

What Kind of Meat Hook Reefer Truck Is Better?

1. Reefer trucks for transporting cold meat must have overall sturdiness, impermeability, airtightness, heat insulation, and low temperature.
2. The surface of the meat hook reefer truck body as well as the corners of the back must be smooth design, and it should be corrosion-resistant, easy to clean, antibacterial, waterproof, heat insulation and other functions.
3. Meat hook refrigerated trucks require real-time monitoring and timely adjustment of the temperature of the transported cargo as well as the condition of the cargo.
4. Meat hook refrigerated truck configuration of the refrigeration unit, the lowest refrigeration temperature in the box can reach -18 ℃, and need to maintain a constant temperature and good ventilation.
5. The top of the cargo compartment of the meat hook refrigerated truck is equipped with 2 to 5 aluminum alloy meat hook rails, the rails are divided into longitudinal groove and docking rails, in addition to the addition of a fixed stopper to prevent the white strips from swinging and reduce the friction of collision.
6. Generally after the transportation of cold meat food need to be thoroughly cleaned and disinfected cargo compartments, and the disinfectant solution has a certain degree of corrosiveness.

How to Customize a Quality Meat Hook Reefer Box?

Carbodygroup is a leading provider of Meat Hook reefer truck solutions, specializing in customized reefer truck bodies for transporting chilled meat, with interior body wall panels made of a continuous fiberglass layer + PU insulated core + embedded reinforced composite, which is ultra-lightweight, corrosion-resistant, anti-microbial, impact-resistant and easy to clean.

If the bottom of the box stacked goods can be assembled with aluminum alloy ventilation slots, the floor adopts a multi-layer structure: the upper layer is made of thickened aluminum groove flooring or non-slip stainless steel, FRP (fiberglass-reinforced plastic) as the inner skin material, the core material is polyurethane foam, and the internal increase of one layer or two layers of plywood, to enhance its compressive strength and load-bearing capacity, to ensure the Safety, stability and ventilation when transporting heavy goods.

What Are the Considerations for Loading a Meat Hook Reefer Truck?

Meat hook refrigerated truck transported beef and lamb, pork, chicken and other white meat need to be in the cold storage after 24 hours of frozen processing, more large pieces of meat time is longer, measuring the meat center temperature to reach the surface temperature consistent with the best, usually -18 ℃, some requirements -23 ℃.

Meat in the process of loading out of the warehouse, turnover loading and unloading platform temperature can not be placed at room temperature, usually maintain a temperature of 10 to 15 degrees to ensure that the meat is not due to excessive temperature changes and surface condensation.

Before loading, the vehicle refrigeration unit must be turned on to pre-cool the box for a minimum of 30 minutes. Strictly speaking, the refrigeration unit should be allowed to defrost once. Slaughtered meat on the temperature requirements of 0 degrees below, the goods are cold contraction, to exclude a certain amount of water, so must use the refrigeration unit with defrost function.

Meat loading is completed, close the door of the refrigerator box, hit the cold half an hour so that the temperature is lowered and then send the car is better.

Why Does the Temperature Inside the Box Rise When Defrosting?

In order to transport the chilled meat to the destination faster, the slaughtering plant usually does not have pre-cooling or shorter pre-cooling, and directly loads the truck for transportation. Without thorough pre-cooling of the cold meat will produce a large amount of water vapor, affecting the cooling unit cooling caused by repeated frost, if necessary, to take the ventilation cooling.

In addition a variety of cold meat by cold compression produces moisture, refrigeration unit so that the internal temperature of the box down to the freezing point, the air outlet temperature is lower and finally frost, serious blockage of the air outlet, affecting refrigeration. Therefore, in order to ensure the transportation temperature of the goods, meat hook refrigerated trucks must use the refrigeration unit with defrost function, through the electric heating wire heating, or with heating defrost function, the air outlet of the frost melting, defrosting process, refrigeration unit evaporator stops working, defrosting time according to the length of different brands of refrigeration unit varies, commonly used refrigeration unit defrosting time is about 10 to 15 minutes (adjustable), therefore. In the whole defrosting process, the chiller will stop working, and the internal temperature of the box will be warmed up.

What Is the Difference Between a Reefer Truck and a Cold Storage?

Reefer is a refrigerated special transportation vehicle equipped with refrigeration unit of refrigeration device and polyurethane heat insulation compartment. Cold storage is actually a kind of low-temperature joint cold air equipment, refrigeration equipment, refrigeration principle is basically equivalent to refrigerated trucks, but the refrigeration area is large, the refrigeration speed is fast, the refrigeration effect is better.
