Hey there! As a supplier of Hand Towel Tissue Machines, I often get asked about the drying system in these machines. So, I thought I'd share some insights on what the drying system in a hand towel tissue machine is all about.
First off, let's understand why a drying system is so crucial in a hand towel tissue machine. Hand towel tissues need to be dry enough to be used effectively. If they're too wet, they'll be weak and won't hold up well when you try to use them. And nobody wants a soggy hand towel, right?
There are a few different types of drying systems that can be used in hand towel tissue machines. One of the most common ones is the Yankee dryer. The Yankee dryer is a large, steam-heated cylinder. The wet tissue web is pressed against the surface of this cylinder, and as the steam inside heats up the cylinder, it dries the tissue. This process is really efficient because the large surface area of the Yankee dryer allows for a lot of moisture to be removed quickly.
Another type of drying system you might find in a hand towel tissue machine is the through-air dryer (TAD). In a TAD system, hot air is blown through the wet tissue web. This helps to evaporate the moisture from the tissue. The advantage of a TAD system is that it can produce a softer and bulkier tissue compared to the Yankee dryer. This is because the hot air doesn't compress the tissue as much as the pressure against the Yankee dryer does.
Some hand towel tissue machines also use a combination of both Yankee and TAD drying systems. This way, they can take advantage of the benefits of both methods. For example, the Yankee dryer can be used for the initial drying stage to remove a large amount of moisture quickly, and then the TAD system can be used for the final drying to give the tissue a softer feel.
Now, let's talk a bit about how these drying systems work in the overall process of making hand towel tissues. It all starts with the pulp. The pulp is a mixture of wood fibers and water. This pulp is fed into the forming section of the machine, where it starts to form into a continuous web of tissue.
Once the tissue web is formed, it moves on to the drying section. If it's a Yankee dryer system, the wet tissue web is guided onto the surface of the Yankee dryer. The steam inside the dryer heats up the cylinder, and as the tissue comes into contact with the hot surface, the moisture starts to evaporate. The tissue is then peeled off the Yankee dryer, and it's already much drier than when it first entered the drying section.
If it's a TAD system, the wet tissue web is placed on a porous belt. Hot air is then blown through the belt and the tissue web. The hot air picks up the moisture from the tissue and carries it away. This process continues until the tissue reaches the desired level of dryness.
The drying system also has some controls to make sure that the tissue is dried just right. For example, there are sensors that measure the moisture content of the tissue. If the tissue is too wet, the machine can adjust the temperature or the speed of the drying process to remove more moisture. If it's too dry, the machine can reduce the heat or slow down the process to prevent the tissue from becoming brittle.
When it comes to choosing a hand towel tissue machine, the drying system is an important factor to consider. If you want a machine that can produce a large volume of hand towel tissues quickly, a Yankee dryer system might be a good choice. It's efficient and can handle high speeds. But if you're looking for a machine that can produce a softer and more luxurious hand towel tissue, a TAD system or a combination of both systems might be more suitable.
