The bread refrigerated truck is small and exquisite, easy to transport, and can quickly travel through the urban areas. However, there are some problems that need to be prepared. There are some special circumstances that must be handled correctly to ensure the quality of the transportation. I will briefly introduce some issues below. And disposal methods. First of all, I would like to say a few preparatory work before transport. Only sufficient preparation work will avoid some problems in the transportation process. When the goods are shipped, the other party to the goods should be placed on the double-sided pallets of the bread refrigerated truck and the bread should be refrigerated. Do not cover some plastic film on the pallets, otherwise it will hinder the circulation of the air-conditioner, and it can not block the floor of the goods line. This is the key to ensure the uniform temperature protection of the goods during the refrigerated truck transportation. Commonly used ventilation aluminum floor, or flat non-slip floor, this non-slip floor is generally transport companies or dairy transport companies in the use of refrigerated trucks, pay attention is not to dump cargo in the refrigerator car vents, to prevent obstruction Air-conditioning leads to a short-circuit of the air-conditioning. If the top of the goods is stacked, it is better to keep the distance from the top of the refrigerated truck to a distance of not less than 225mm. When loading the goods, avoid the height of the goods being stacked too high and ensure that the height of the air vents of the refrigerated truck is not higher than the level of the vents of the refrigerated truck. Being blocked or being too close to the cargo will affect the temperature in the refrigerated compartment, even Caused by the normal operation of refrigerated trucks refrigeration units, once the vents blocked, we can not guarantee the circulation of cold air will cause local temperature inside refrigerated trucks increased. The design of defrosting of refrigerating units of refrigerated trucks adopts air induction. When the goods are too close to the vents, the coils in the evaporators of refrigerated trucks will have frost and ice, and the defrosting will start only when the The defrosting will stop when the temperature of the refrigerated truck coil rises to a certain temperature, then the above situation will occur repeatedly when the cargo is too close to the vent of the refrigerated truck, resulting in no decrease in the temperature of the refrigerated truck box, which is visualized as repeated defrosting. in fact refrigerated cargo vehicles piled too high a problem. Plastic Profile Extrusion Line Plastic profile extrusion is a process of manufacturing plastic profiles of various shapes and sizes. The process involves melting plastic pellets and extruding them through a die to create a continuous profile. A plastic profile extrusion line is a set of machines and equipment used to carry out this process.
The plastic profile extrusion line can be used to produce a wide range of products, including window frames, door frames, decking, fencing, and pipes. The process is highly efficient and can produce large quantities of profiles in a short amount of time.

The plastic profile extrusion line consists of several components, including a hopper, extruder, die, cooling system, and haul-off system. The hopper is where the plastic pellets are loaded into the machine. The pellets are then melted in the extruder, which is a long barrel with a screw inside. The screw rotates and pushes the plastic through the barrel, melting it as it goes.
Once the plastic is melted, it is forced through the die, which is a specially designed tool that shapes the plastic into the desired profile. The die can be customized to produce many different shapes and sizes of profiles. The plastic profile is then cooled using a cooling system, which can be air or water-based.
After the plastic profile is cooled, it is pulled through the haul-off system, which is a set of rollers that control the speed and tension of the profile. The haul-off system also ensures that the profile is straight and uniform in shape.
