Pyrolysis is a type of thermal chemical treatment of biomass carried out under anaerobic conditions and at temperatures ranging from 200 to 300 degrees Celsius. This treatment can cause beneficial changes in biomass, such as improving grinding performance, increasing calorific value, reducing the contents of chlorine, nitrogen and sulfur, decreasing the equilibrium moisture content, and enhancing the resistance to biodegradation.

Fibers and the like are the final products formed after a series of complex processes such as mixing, dissolving, spinning and drying. The quality of the fibers depends on the dissolution step in the preparation of the original solution. Only completely dissolved raw materials can form a uniform, pure and bubble-free spinning solution. This solution then needs to be further processed through an adjusted spinning nozzle. At the same time, the dissolution and spinning processes must be flexible enough to adapt to different types of raw materials. The dual-axis self-cleaning equipment of KaiZheng Company has been successfully applied in this type of process. In the later stage of the dissolution process, its viscosity can reach 5000 Pa.s, and in extreme cases, it can reach 100000 Pa.s.

Lyocell fiber technology aims to convert cellulose into a man-made, cotton-like fiber. The lyocell process involves a series of processing steps, with the dissolution step being the most critical. A kneader developed by KaiZheng has been successfully applied in the continuous dissolution stage, enabling the treatment of raw materials from various sources and their conversion into spinnable dope.
