Be careful with the parts on the tunnel drying equipment
Sweater Sweaters are knitted by machine or by hand. The history of sweater knitting is very long. Human beings used leaves and animal skins to cover their bodies in primitive life, and later learned to use knitting techniques, so sweaters were produced. With the evolution of civilization and the invention of technology, there are more and more types of sweaters, with better and better quality. The function of sweaters is generally to keep warm, but with the progress of mankind, people began to pursue the beauty of sweaters.

The tunnel dryer consists of two parts: the conveyor system and the drying furnace. The conveyor system is a small car whose speed can be adjusted to increase the mobility during the drying process. At the same time, the loading of materials in the trolley enables full utilization of the dry space. Of course, the track of the trolley is equipped with a chain drive on both sides to avoid the phenomenon of deviation during transportation.
The drying furnace section is usually divided into several temperature sections, and segmented heating is implemented, and each section is controlled by an independent PID temperature, which makes the equipment downsized, can ensure uniform temperature in a certain space, and avoid heat generation due to excessive space. Uneven distribution. Because each temperature control is independently adjusted, the equipment can be continuously and continuously baked to improve the production efficiency of the product.
During baking, the windshield on the food material trolley of the tunnel dryer rises, the hot air passes vertically through the material layer, and is reversed multiple times, so that the material and the drying medium in the entire drying interval are horizontally and vertically changed. This process recycles the heat generated by steam boilers and hot blast stoves (burning coal, fuel, gas) to improve thermal efficiency. In addition, the exhaust gas can also realize the fantasy. By installing the through-flow drying equipment in parallel with the two tunnels, the upper part is equipped with an axial flow fan, so that the hot air enters a certain amount of outside air while passing through the two rows of tunnel material layers in the section. A certain amount of exhaust gas is discharged to perform partial exhaust gas recirculation.
The tunnel dryer has strong adaptability. As we have said above, the speed of the conveyor system can be adjusted, and the temperature of the drying furnace is independently controlled by the temperature control system, which means that the humidity and temperature can be controlled. According to the characteristics of the material, the tunnel dryer can quickly change the drying process and has wider adaptability. At the same time, if the dried material is fixed, the equipment can be designed into a fully automatic or semi-automatic mode to reduce the difference in material drying caused by insufficient worker experience. For different material characteristics, the baking tray on the trolley can also be replaced, such as plastic mesh tray, wood strip, wire mesh, bamboo net, etc.
Of course, length and volume are not the only features of tunnel drying equipment. For the drying equipment, it is a device that converts the energy generated by the steam boiler into heat energy, thereby evaporating the moisture of the food. Most of the current tunnel dryers are made of stainless steel, which has strong thermal insulation properties, which can prevent heat from overflowing and save energy. This is also an improvement in the working environment of the drying section staff.
The tunnel furnace can be adjusted with many components. During daily use, it is also necessary to check whether the various components are in normal operation. For example, the fan, current, thermostat, heating pipe, delay device and other components will cause drying effect. Great discount. It can be seen that even if the giants are like tunnel drying equipment, they need to pay attention to the details in the production, so as to avoid the effect of the equipment being greatly reduced due to the details of the errors.
Our company can produce various styles of sweaters. You are welcome to provide drawings and we will customize them for you.
