How a dryer works
Firstly, the items to be dried are sent to the trailer through the delivery facility, and the feeding timing in the trailer is sent to the feeding end, and then enters the dryer from the feeding end. The drum of the dryer is slightly skewed to the extent, and the items enters the drum from the higher end. The same heat carrier enters from the other end to form a reverse contact with the items. Because the drum is slightly skewed, the items are moving directly or indirectly by the heat carrier to get dried. Then the items are sent out by the discharge end.
At the same time, the outside of the drum is equipped with a board, which can lift the items and put them down. Because the parallel surface of the items and the cyclone become larger, the drying rate will be slowed down. The heating medium has a normal warm atmosphere and a channel gas. After the heat carrier passes through the dryer, it is normal to separate the heat carrier from the articles to be carried by the claw dust collector. At the same time, it should also be equipped with a bag filter and a wet dust collector, which can further reduce the dust content of helium.
How long should a dryer last
Intermittent fixed-bed dryers have been spread recently. In the middle of the 19th century, the use of tunnel dryers marked the development of dryers from intermittent operation to continuous operation. The rotary cylinder dryer achieves better agitation of the granular materials and improves the drying capacity and strength. Some industries have developed continuous operation dryers that meet the requirements of this industry, such as drum dryers in the textile and paper industries.
Is it worth fixing a dryer
The development of the dryer industry is relatively stable, and the market prospect is relatively broad. However, there are still a series of problems to be solved, which is high costs. Obviously, fixing a dryer is quite economic, because purchasing a new dryer can be quite expensive. When your dryer gets in trouble, you might think to get a new one instead of fixing it. But it is really more economic to fix the old dryer than purchase a new one, because the cost of former is less than the cost of latter.
Does a dryer kill germs
There are two kinds of working principle, which are hot air flow type and radiation type in the drying process of the material. Hot air drum drying is the hot air flow moving forward from the tail, fully contacting the material, and making full use of the heat conduction, convection, and radiation heat transfer. The heat energy is directly transferred to the material , so that the moisture of the material can be continuously evaporated in the cylinder. The air intake device at the feed inlet draws a large amount of water and moisture zhidao flow to prevent secondary pollution caused by the external discharge of the dust. Through the internal spiral stirring, sweeping and copying board, the material movement is advanced to complete the entire drying process.
