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.

Difference Between Refrigerated and Freezer Trucks

1. Refrigerated trucks

• Temperature range: Typically 0°C to 4°C (32°F to 50°F).
• Purpose: Refrigerated trucks are used to transport items that need to be kept at a lower temperature but do not need to be completely frozen. The refrigerated environment extends the shelf life of the goods and inhibits the growth of bacteria and micro-organisms. It is suitable for transporting vegetables, fruits, beverages, etc. These goods will affect their quality if frozen. Refrigerated trucks ensure that these products maintain their freshness.

2. Freezer Trucks

• Temperature range: Typically -18°C to -20°C (0°F to -4°F), up to -30°C to -40°C on some models.
• Uses: Freezer trucks are suitable for goods that need to be kept completely frozen at low temperatures, such as meat, ice cream, seafood and some medicines. Refrigerated trucks are suitable for long-distance transport, especially intercity transport.

3. Multi-temperature Zone Refrigerated Truck

• Temperature range: Multiple temperature intervals can be maintained simultaneously, typically between -20°C and 4°C.
• Purpose: Multi-zone refrigerated trucks have spaces divided into multiple zones, each of which can be adjusted to a different temperature to accommodate both refrigerated and frozen items. For example, some zones can maintain temperatures between 0°C and 4°C to transport fruits and vegetables, while other zones can maintain temperatures of -20°C to transport frozen foods such as ice cream. They have a wide temperature range and can carry a variety of goods in the same transport.

Here are a few important tips for caring for and maintaining your gel-coated fiberglass panels:

Clean Regularly

The gel-coat surface is relatively stain-resistant and can be cleaned with a mild liquid detergent. However, avoid using cleaning products that contain abrasive ingredients, strong alkalis, or high acids, as these can damage the coating and cause surface discoloration, loss of gloss, and aging. Soapy water or a fiberglass panel cleaner specifically designed for the recreational vehicle, box truck, and marine industries is your best choice.

Cleaning steps

• Use a soft cloth or sponge to wipe the surface without applying too much force.
• After cleaning, rinse with clean water to avoid residual detergent.

Things to note

• Avoid using hard-bristled or dirty brushes.
• If there are bird droppings, resin or tar on the surface, remove it as soon as possible to avoid permanent stains.

Treat Stubborn Stains

For stubborn stains that are difficult to remove, you can use a small amount of mineral oil and apply it to a cleaning cloth, gently wipe the stained area, and wait until it softens before cleaning. Finally, clean the surface with clean water.

Regular Waxing Protection

Regularly waxing the surface of gel-coated fiberglass panels can protect their luster and durability, just like coatings on box trucks, recreational vehicles, and boats. Waxing can form a protective film to prevent damage to the surface from UV rays, stains, scratches, and other factors. It is recommended to use an abrasive wax specifically designed for fiberglass panels found on box trucks, RVs, or boats.

Waxing steps

• Use a non-abrasive wax to avoid wearing away the coating.
• Use a soft cloth to spread the wax evenly over the surface.
• Make sure the wax layer is even and there is no residue on the surface.

Suggestion:

For fiberglass panel applications frequently exposed to outdoor environments, such as box trucks, recreational vehicles, boats, and modular buildings, wax every 3 to 6 months, and 3 months for dark-coated products.

Storage and Protection

• Keep the panel or related application products in a cool, dry place.
• Avoid moisture accumulation that can cause discoloration.
• Regularly inspect surfaces for stains or erosion.

Restoration and Repair

Such as repairing fiberglass PU foam sandwich panels for refrigerated truck bodies.

1. Clean the stains.
2. Mix the resin, curing agent and accelerator according to the amount.
3. Apply to the damaged area.
4. Lay the fiberglass panel.
5. Apply the resin again until it is level with the fiberglass panel.
6. After the glue is cooled and dried, sand it flat.
7. Mix the silica or talcum powder into a viscous state and mix it with the curing agent according to the proportion.
8. Apply to fiberglass panels with a scraper and scrape smooth.
9. After drying, sand the surface flat and spray paint.

Components of a Refrigerated Truck

• Refrigeration unit: This is the main part of the refrigerated truck. Simply put, it cools the cargo area.
• Insulated box or trailer: This is where the cargo goes, and it helps limit heat from getting in, as long as the right temperature is kept.
• Power source: Refrigeration units are available as either diesel-driven or fully electric-driven.

Factors Affecting the Service Life of Refrigerated Trucks

The service life of a refrigerated truck is affected by a variety of factors, including component quality, maintenance methods and usage habits. We’ll discuss these factors in more detail below.

Component quality

High-quality parts are the foundation of a reefer truck’s longevity. Choose a trusted and technologically advanced partner, such as CarbodyGroup’s customized refrigerated truck bodies, which feature premium insulation that significantly improves vehicle durability.

Maintenance Methods

Regular maintenance is an important factor in prolonging the service life of refrigerated trucks. It involves regular inspections, prompt repairs and preventive measures to ensure that each component is in optimal working condition. If maintenance is neglected, it will lead to breakdowns and high repair and modification costs, thus reducing the service life of the truck.

Usage Mode

Trucks that are often overloaded or traveling on uneven terrain experience more severe wear and tear, and frequent start-stop cycles can also add to the burden on the refrigeration unit and engine, which can accelerate their aging.

What Is the Average Service Life of a Refrigerated Truck?

A well-maintained refrigerated truck can last 8 to 15 years, assuming it runs 8 hours a day year-round. The total operating hours are between 20,000 and 40,000 hours. However, the factors mentioned previously will affect the life of a truck, and if the trucks are of good quality and well maintained, they can last longer than this period. Nonetheless, their maintenance will significantly affect their lifespan; for example, when a truck is 8 years old but poorly maintained, it will need to be replaced.

The Difference Between Refrigerated Trailers and Refrigerated Trucks

Refrigerated trucks are an integrated design suitable for short-distance urban delivery, with good maneuverability but smaller capacity; while refrigerated trailers require a tractor to tow, are suitable for long-distance transportation and bulk goods, and provide larger cargo space and greater flexibility.

Tips for Extending the Life of Your Refrigerated Trucks

To maximize the life cycle of refrigerated trailers and refrigerated trucks, it is necessary to perform regular, professional maintenance and repairs. By recognizing potential problems early and taking effective repair measures, breakdowns can be prevented and vehicle maintenance costs reduced.

Maintenance of Key Parts

The main components of refrigerated trucks are refrigeration units, heat preservation and sealing performance, etc. Regular overhaul and maintenance of these components can significantly extend the overall service life of refrigerated trucks.

1. Maintenance of Refrigeration Units

The refrigeration system of the refrigerated truck needs to be inspected and maintained on a regular basis. It is recommended to check the belt drive and overall function etc. every 2-3 hours. Typically, the oil filter needs to be changed every 30,000 hours of operation or every 2-3 years. In addition, a routine inspection is required every 800 hours of operation to identify potential problems in advance and prevent major breakdowns.

2. Daily Self-Check

• When loading, make sure there is enough space around the goods to allow for air circulation.
• Start the cooling system 1 hour before loading to ensure that the temperature inside the vehicle reaches the set standard.
• Clean the inside of your refrigerated truck daily to prevent mold growth and moisture damage.
• Regularly check the operation of the refrigeration system to ensure that there is no condensation.
• Monitor the temperature changes in the vehicle at all times to ensure that the temperature remains within a safe range.
• Regularly check the controls of your refrigeration equipment to prevent malfunctions.
