The main function of drying box is to remove moisture from paper. In the process of papermaking, the newly formed paper contains a lot of water, and the water is evaporated by using heat energy through the drying box to make the paper reach a suitable dryness. The drying efficiency of drying box will affect the quality and production speed of paper. If the drying is uneven, the paper may have problems such as wrinkles and inconsistent strength; Too slow drying speed will reduce the overall efficiency of papermaking.

Suitable for drying all kinds of paper, such as writing paper, wrapping paper, household paper, etc. For writing paper, the drying oven can accurately control the dryness of the paper, so that the ink can be absorbed well without smudging when writing; In the manufacturing of packaging paper, proper drying can ensure that the paper has enough strength to bear the weight and friction of the packaged goods; After the household paper is dried in the drying oven, it will become soft and have good water absorption.

1. Temperature uniformity

The internal heating system can ensure that the temperature distribution in the whole drying space is relatively uniform. For example, through the reasonable layout of multiple drying cylinders, all parts of the paper can receive more balanced heat during operation, so as to avoid the inconsistency of paper drying degree caused by temperature difference, which is very important to ensure paper quality.

2. Fast drying speed

It has an efficient drying capacity, which benefits from a powerful heating source and good ventilation conditions. The water content of paper can be effectively reduced by staying in the drying oven for a short time, and the expected drying effect can be achieved quickly, thus meeting the requirements of efficient production of paper production line.

3. High degree of automation

Can be equipped with advanced automatic control system. These systems can monitor and control key parameters such as temperature, humidity, paper speed and tension in real time. For example, when the temperature is detected to deviate from the set value, the heating power can be automatically adjusted; When the paper tension changes, the relevant devices will be adjusted in time to ensure the stability and reliability of the whole drying process.

4. Good operation stability

The mechanical structure and electrical system design of the drying box of paper machine are reasonable, which ensures the long-term stable operation. The quality and connection mode of its components are carefully designed, which reduces the probability of failure, equipment maintenance cost and production downtime.
