Paper tube/paper shaft drying status

1, large-scale factories use electric heating grill, large power consumption, high cost.

2, the electric heating drying method has a high temperature, which is easy to lead to the phenomenon of uneven heating of the paper tube/paper shaft and travel deformation and delamination degumming. The excessive temperature of electric heating can even cause burning or burning in serious cases

The fire.

3, the general life of the heating pipe is three to five months, and the maintenance and replacement are frequent.

4. Some factories use steam drying. Due to improper control of steam temperature, it is easy to lead to high temperature and produce drying quality problems.

5, small-scale factories use natural drying or air drying methods. Long production cycle and low efficiency. It is greatly affected by the weather and cannot be continuously produced. The labor intensity is large, and the quality of drying is difficult to be effective

Control.

Several important questions

1, temperature - the drying temperature of the paper tube is relatively high, generally required to be above 45 ° C.

2, humidity -- the paper tube contains little water content, the main paper tube lamination production for bonding glue. Controlled drainage saves energy.

3, drying time -- through the general drying time is 8-10 hours; This has a lot to do with the diameter, thickness and glue properties of the paper tube.

4, straightness/roundness -- For many paper tube products, it is important to keep the straightness and roundness of the paper tube after drying; The axial and radial deformation of the paper drum must be controlled in the drying process.

5, hardness/strength - this is also an important indicator of the quality of paper tubes.

Naisida Solutions

1, the use of high temperature dryer to dry the paper tube/paper shaft. The drying process has low energy consumption and effectively reduces operating costs.

2, drying process through the hot air medium heating, temperature distribution is reasonable.

3, the paper tube is heated evenly, reduce the axial and radial deformation of the paper tube, effectively reduce the hidden danger of drying quality caused by the roundness, straightness and lack of strength, and the drying effect is good.

4, safe and reliable, drying process without overheating or burning danger.

5, the drying process is automatically controlled by the temperature and humidity system, with high precision. Effectively avoid drying or excessive drying caused by manual control. Reduce labor intensity, reduce operating costs
