If the tunnel kiln drying room is dry, let s do it

There are several reasons why the materials in the drying room do not dry:

First, the drying time is not up to the requirements, the drying time is short, only the outer skin of the material is dried, and the inside of the material is still not dry.

Second, the water content of the discharged material is too low, so we increase the amount of fuel used. However, when operating this method, we should adjust slowly, not largely, the temperature in the drying room is too high or the temperature rises too fast, and the drying materials can not meet the product quality requirements.

Third, the material does not dry, and the temperature of the hot air circulation in the drying room is inconsistent, such as the temperature on the left and right sides is inconsistent, in this case, we should change the hot air circulation mode, such as changing to blowing air on the left and right sides or blowing up and down. In another case, a deflector should be set up in the drying room, if the deflector plate is not set, the hot air can not come back, the air circulation is not good, and the main role is to divide the air.

Fourth, you can check the fan power of the drying room, such as the height, length and width of the drying room should be matched with the fan power. If the power of the fan is small, the hot air circulation will not be able to reach it.

Fifth, the humidity discharge of the drying room is not in place, the power of the humidity exhaust fan of the drying room is too small, and the input value of the humidity discharge and the input temperature of the drying room are not proportional.

The drying does not dry the billet, and the phenomenon is that the heating temperature is low.

The root cause is to increase the heating temperature, dry and pour or preheat the fried blank.

If the root cause of the inverted blank is solved, the problem of drying is solved.

Different types of raw materials, different levels of raw material moisture, insufficient molding pressure, insufficient extrusion strength, too short drying line, unreasonable structural design of drying kiln, high drying air temperature, large moisture exhaust resistance, small exhaust air volume, low temperature will be the cause of inverted billets, different reasons and different treatment methods can be viewed in my homepage, there are articles dedicated to analyzing inverted billets.

Your drying chamber is estimated to be positive pressure and drain the tide, and if the negative pressure increases on a rainy day, the moisture will definitely fall. It is recommended to change the drying room to a fan to drain moisture. The drying room is made in an air circulation room.

Hello, the reason is as follows: the tunnel kiln drying room generally adopts a continuous drying method for drying, and the inverted billet is a common way to troubleshoot. When the quality of the green body in the drying room does not meet the requirements, the blank is usually inverted, and then the socks are restarted drying.

Before the inverting of the blank in the drying room, it is necessary to conduct a certain analysis of the previous operation process and the actual production situation, so as to find the cause of the inverted billet and solve the problem, so as to achieve the purpose of improving product quality and production efficiency. The specific causes of billet inversion in the drying chamber of tunnel kiln include, but are not limited to: unequal or uneven billet size, lack of sintering agent or other additives to reduce the burn loss rate, uneven combustion process or improper control, resulting in solid billet, deformation or cracks, etc.

Therefore, different solutions need to be implemented for different reasons for billet inversion, such as adding appropriate additives in the preparation process, adjusting the temperature and humidity of the drying room, changing the fuel use and control mode, etc. It should be noted that inverting is only a measure to deal with the problems that occur during the drying process, and it is fundamental to solve the problem. If inverting is frequently required, the current drying process may need to be further refined and optimized.

Summary. Different types of raw materials, different levels of raw material moisture, insufficient molding pressure, insufficient extrusion strength, too short drying line, unreasonable structural design of drying kiln, high drying air temperature, large moisture exhaust resistance, small exhaust air volume, and low temperature will be the reasons for inverted billet.

Different types of raw materials, different levels of raw material moisture, molding pressure does not let the group be full, extrusion strength is not enough, the drying line is too short, the structure design of the drying arubber kiln is unreasonable, the drying air temperature is too high, the moisture discharge resistance is large, the tide exhaust air volume beam is small, and the low temperature will be the cause of the billet.

The kiln design of each company is different, and the temperature of the optimal hole for drying is also different, and the drying effect is even more varied. In the season with the highest temperature, the general drying room can be controlled at about 120 degrees, and the output is relatively high. In winter, it is generally controlled at 60 degrees, although the output is low, but the billet is not poured.

The kiln designed by our company has a heating temperature of 260 degrees Celsius throughout the year and a temperature of more than 160 degrees in the drying kiln.

Hello dear <>

There are many possibilities for the reasons for <> tunnel kiln drying chamber inverted, and the following are some common reasons:1Kiln temperature is unstable:

If the kiln temperature is unstable, it will cause the temperature in the kiln to be too high or too low, which will affect the drying effect of the green body and lead to inverted billet. 2.The quality of the green body is uneven

If the quality of the green body is uneven, it will lead to inconsistent moisture content inside the green body, which will affect the drying effect and lead to inverted blank. 3.Poor ventilation of the drying room:

If the ventilation of the drying chamber is poor, the moisture on the surface of the green body will not be able to evaporate in time, which will affect the drying effect and lead to inverted blank. 4.The temperature of the drying chamber is too high:

If the temperature of the drying chamber is too high, it will cause the moisture on the surface of the green body to evaporate too quickly, resulting in the formation of a hard crust on the surface, and the internal moisture cannot be discharged smoothly, resulting in the inversion of the blank. 5.The humidity of the drying chamber is too high

If the humidity of the drying chamber is too high, the moisture on the surface of the body will not be able to evaporate in time, which will affect the drying effect of the wax fruit and lead to the inversion. In short, there are various reasons for the inversion of the billet in the drying room of the tunnel kiln, and it is necessary to analyze and deal with the wheel marker according to the specific situation. It is recommended that you pay attention to controlling factors such as temperature, ventilation and humidity when using the tunnel kiln drying chamber to ensure that the green body can be dried smoothly.

Summary. Hello, it is a pleasure to serve you, I have received your question, I am sorting out the answer for you, it takes time to type, please be patient for a while, and answer it for you immediately!

Hello, I am glad to serve you, I have received your question, and I am sorting out the answer for you, it takes time to guess the word on the bridge, and please be patient and wait for a while, and answer it for you immediately! Potato eyes.

Hello, here are three reasons for you: the original celery oak material of the brick is not suitable for making bricks; The brick material is not uniform; The bricks are not compacted. It may be that the temperature rises too fast and the temperature is too high, and the water inside the brick does not have time to evaporate, so the internal volume expands and the billet collapses.

The inlet temperature of the drying kiln can be adjusted appropriately to allow the bricks to heat up slowly over time. Suspicion aside.
