Pulp is the raw material for making paper and cardboard, which is a fiber material made from plants (such as wood, cotton, agricultural waste) or recycled paper, and is formed by decomposing and mixing with water. Wet pulp is a fiber suspension with high moisture content. Due to its high moisture content, it is easy to breed bacteria, rot and mold, and greatly increases transportation costs. At present, the most commonly used paper pulp processing method is to use a paper pulp dryer to reduce the moisture content of the pulp to 10-15%, turning wet pulp into dried pulp. Dried pulp has a small volume, light weight, greatly reduces transportation costs, and extends shelf life to over 1 year. The standard for dried pulp is unified and can be used for re pulping by paper mills in various regions.

Process flow of paper pulp dryer

The "three cylinder multi return" paper pulp dryer produced by Zhengzhou Jiutian is based on the single cylinder dryer and has been innovatively designed and modified. Due to the high moisture content of pulp and its composition of multiple fibers, excessive drying temperature can easily lead to fiber plasticization and even fire; On the contrary, if the drying temperature is too low, it cannot meet the drying requirements. Therefore, drying pulp is difficult, and temperature control is particularly important. The device adopts the "three-stage multi loop drying technology", which divides the entire drying process into three stages. Then, based on the characteristics and requirements of the pulp, freely allocate and independently adjust the air volume, wind speed, wind direction, and heat; Water vapor is promptly discharged at the end of each stage, greatly improving drying efficiency. Meanwhile, the moisture content of the dried material can be precisely controlled according to the range required by the customer.

Advantages of paper pulp dryer

1. The equipment adopts a three cylinder structure, greatly reducing the equipment's footprint.

2. Automated operation, high degree of intelligence, low labor intensity, and easy operation.

3. The process technology is mature, the performance is stable and reliable, it can operate continuously for 24 hours, and the equipment failure rate is low.

4. The equipment has strong processing capability, high thermal energy utilization rate, energy conservation and emission reduction, and reduces production costs.

5. The equipment is tightly sealed as a whole, operates under negative pressure, and there are no flammable or explosive phenomena during the production process.

6. The equipment adopts the "low-temperature high air flow" drying process, which not only improves the drying efficiency of the equipment, but also saves energy consumption, while ensuring the quality of the finished pulp material after drying.
