Exploring the secrets of refrigerated compartments

As an important transportation equipment in cold chain logistics transportation, refrigerated trucks are the key to ensuring the safety of perishable and fresh food during transportation. Our common transportation products are different and have different names. For example, those that pull fruits and vegetables are called "fresh trucks", those that pull pork and seafood are called "frozen trucks," and those that pull milk are called "fresh milk trucks." But at first glance, it's really hard to distinguish. Next, let's look at the differences in the refrigerated compartment.

　　●Refrigerated truck or insulated truck is only one refrigerator away

　　 Refrigerator truck is mainly composed of automobile (trailer) chassis, heat preservation (heat insulation) compartment, refrigeration device and accessories. If there is no refrigeration device, it is an insulated car. Of course, the insulated car can keep "cold" or "hot". Its existence is the same as the small box behind the delivery car, mainly to maintain the temperature of the goods Certain, not in a short period of time, rapidly decline or rise. Therefore, compared with refrigerated trucks, this kind of insulated truck is mainly used for short-distance transportation, and the model is also smaller, which can adapt to urban freight distribution and shuttle between narrow streets.

　　●Fang Fangzheng is not simple The secret in the "box" of the refrigerated truck

After the 　　 insulation truck is equipped with a refrigeration device, it becomes a refrigerated truck. At present, there are roughly two types of compartment structures of domestic refrigerated trucks; plate assembly structure and integral foamed structure. The article "Teach you to buy a high-quality refrigerated truck from the source" is recommended. Although the body structure of different refrigerated trucks is However, the ultimate goal of z* is to make the car body have good airtightness and heat insulation effect, and to ensure that the goods are in a stable and suitable temperature environment.

　　The refrigerated trucks that transport fruits and vegetables and the ones that pull frozen meat and seafood are just a big box from the outside, there is no difference, but when you open the door of the cargo compartment, you will find "there is no hole in the sky".

　　 According to the needs of different users, ventilation devices, refrigeration devices, shelves, suspension devices, article fixing devices, etc. can be installed in the compartment.

　　 Such as: meat hook truck, this kind of refrigerated truck specializing in the transportation of slaughtered raw meat, can be equipped with meat hooks, pipe cargo troughs, struts, waist, aluminum alloy guide rails, ventilation troughs and other optional components.

　　 The sharp hook is very sharp, and the pork is hung neatly on it. After the aluminum alloy guide rail is assembled, the staff will carry it more easily.

　　 Fresh melons and fruits are distributed together, multi-cabin and multi-temperature models become a trend

　　 Different goods transported by refrigerated trucks have different internal temperature settings. Generally speaking, the temperature of refrigerated trucks for transporting vegetables and fruits is controlled at about 2°C. For refrigerated trucks for transporting frozen meat and seafood, the compartment temperature is below -18°C. The low z* temperature of some refrigerated trucks can even reach -30°C.

　　In urban distribution, especially when distributing goods for small supermarkets and fast food restaurants, there are many types of goods and different refrigeration temperatures. In this case, models with multiple cabins, multiple temperature zones and multiple doors come in handy.

　　 This kind of car body side door is a refrigerated car with two doors. It is more common. The whole car is divided into two independent spaces at the front and rear. Different temperatures can be set to place different goods. Both cabin doors are equipped with plastic curtains to prevent the temperature in the cabin from falling during loading and unloading and the loss of air-conditioning.

　　 In addition to refrigerated trucks with double doors and double cabins, there are also refrigerated trucks with multiple temperature and multiple cabins. Entering the carriage, the narrow place on the right is the area with low temperature z*, which can transport frozen meat, etc. For items with lower temperature, the space in the left door has a slightly higher temperature than the left, and can be loaded with cheese , Cheese and other goods. When the partition on the left side is dropped, the remaining space at the rear can be used for loading items at room temperature to meet the needs of one vehicle for multiple uses. And these two areas can be extended to the rear of the vehicle as needed to meet the needs of various refrigerated products.

A refrigerated truck converted from a light commercial vehicle has a simple and beautiful appearance. The compact model can meet the distribution needs of urban small supermarkets. The rear space is divided into upper and lower floors. The cargo does not affect each other and avoids the danger of being crushed. .
