In trucking, a “reefer” is a refrigerated trailer that gets attached to a semi-truck in order to transport perishables and other temperature-sensitive goods. It was originally the ice cream industry that gave birth to the reefer around 1925.
Similarly, What is refrigerated transport?
Refrigerated transport is a method of transporting shipments with specially designed temperature-controlled trucks. The transporting trucks has a built-in refrigeration system which cools the shipments at a regulated temperature all through the process of shipping.
Additionally, What does reefer mean in shipping? “Reefer” is the term used to describe a refrigerated LTL truck. These shipments carry refrigerated or temperature-controlled freight. This protects the goods from deteriorating, perishing, or damaging during transport.
What is a reefer cooler?
Reefer containers are, simply put, large fridges carried by containerships to move temperature-sensitive goods. That can be things as ice cream, meat, or vegetables. Reefer containers are – literally – cool because they keep the cargo at the required temperature. That’s usually between -30°C and +30°C.
What is a reefer box truck?
A reefer trailer or refrigerated trailer is a trailer that can be temperature controlled using a kind of portable HVAC system. Reefers often haul several LTL shipments in one load to more than one location. Anything perishable or that requires a certain stable temperature can be hauled in a reefer.
How does refrigerated transport work?
Air is brought into the condenser through a fan. The evaporator is normally located inside the trailer. … The cool compressed liquid flows through the valve, which controls the amount of refrigerant that is discharged into the evaporator. The refrigerant expands in the evaporator and quickly turns back into gas.
How is refrigerated food transported?
There are four modes of transport: road, water, rail, and air. Transportation methods range from 12-m containers for long-distance water, road, or rail movement of bulk ambient, chilled, or frozen products to small, uninsulated vans supplying food to local retail outlets or even directly to the consumer.
Why is refrigerated transportation important?
The most obvious benefit of refrigerated transportation is that it keeps products from deteriorating and losing their value during the transportation process. This is not only true for food, such as produce, meat and dairy, but also for other sensitive items such as medical products and pharmaceuticals.
What kind of ship is a reefer?
A reefer ship is a refrigerated cargo ship typically used to transport perishable cargo, which require temperature-controlled handling, such as fruits, meat, vegetables, dairy products, and similar items.
What is a reefer ship used for?
Reefer ships are used for transporting perishable cargo—such as meat, fish, dairy, and vegetables—overseas. These ships are specially designed to provide temperature-controlled transportation, allowing safe and efficient shipping.
How does a reefer ship work?
A reefer ship is a special form of cargo ship. As the name suggests, it is used to transport goods that must remain refrigerated during the entire transport or where the cold chain must not be interrupted. These are usually meat or fish, but fruit such as pineapples or bananas etc.
How long will a reefer unit run on a tank of fuel?
Reefer Trailers typically can run for two days without a refuel if opened only once or twice a day. Three days if you go a weekend without opening the trailer if fueled on Friday. If you have staff leaving the door open regularly expect to need fuel daily.
How does a reefer work?
The Compressor – in a reefer unit, the compressor is driven by a small engine. The compressor draws gaseous refrigerant in and compresses it. The pressure inside the compressor liquefies the gas, and the now-liquid refrigerant gives off heat to the body of the compressor, and ultimately to the air.
How cold is a reefer?
The average reefer maintains temperatures within a range of about -13 degrees to 77 degrees Fahrenheit. However, there are highly specialized refrigeration units that go as low as -85 degrees Fahrenheit. These reefers are typically used for the transport of items in the medical and chemical industries.
How big is a reefer truck?
REEFER TRUCK AND TRAILER DIMENSIONS
Typically reefer trailers come in standard lengths between 28 and 53 feet, and do not exceed 13.5 feet in height. The load on a reefer truck should never exceed 44,000 pounds.
What is a reefer engine?
Transport Refrigeration Units (TRUs) are refrigeration systems powered by diesel internal combustion engines designed to refrigerate or heat perishable products that are transported in various containers, including semi-trailers, truck vans, shipping containers, and rail cars.
How are reefer trucks powered?
In a reefer trailer, its compressor is driven by a small diesel engine. The compressor draws gaseous refrigerant in and compresses it. This pressure is then able to liquefy into gas. The liquefied gas then gives off heat to the body of the compressor and the air.
How are refrigerated trucks insulated?
The use of polyurethane foam insulation sandwiched between Aluminum and glass boards is the most common practice within the truck industry.
How cold can a refrigerated truck get?
Refrigerated trailers maintain temperatures between 55 degrees Fahrenheit to -20 degrees Fahrenheit, allowing them to carry a wide variety of cargo. Refrigerated transport has been used to haul medications, flowers, artwork, honey bees, penguins, perfume, electronics and more to the people who need them.
Which things are transported through refrigerated ships?
Reefers (short for refrigerated containers) are large temperature-controlled containers used to transport perishable cargo such as fresh fruits and vegetables, seafood, meat, dairy, flowers, pharmaceuticals, photographic film, and several chilled and frozen goods that might spoil if not maintained at the right …
What is cold transportation?
Cold transport: Specialist vehicles which transport goods in a temperature- and humidity-controlled environment.
How do you transport food without spoiling it?
Keeping food cold by refrigeration or freezing during transport retards spoilage but requires continual energy expenditure to run the compressors in refrigerated transport vehicles.
Why refrigeration is necessary for transportation of goods by sea?
Refrigerated containers (Reefer) are designed to keep a stable temperature inside. Their purpose is to transport goods which need specific conditions for their own good preservation. … Humidity: Humidity levels are very important for preserving ideal conditions during the transport duration.
What are refrigerated trucks used for?
Companies use refrigerated trucks to transport foods and drinks, pharmaceuticals, floral arrangements, and any other product that needs to stay a certain temperature when being moved.
