1. The basic working principle and characteristics of sawdust dryer
Sawdust dryer is a kind of equipment specially used for drying the wet sawdust in the form of powder particles. The working principle is that the wet sawdust is continuously added to the drying tube through the screw conveyor, and the water in the wet material is evaporated in the transportation and dispersion of the high-speed hot air flow, and the powder or granular dry product is finally obtained. The following are the main features of the sawdust dryer:
High drying strength: the material is highly dispersed in the air flow, and the entire surface area of the particles becomes the effective area of drying.
Short drying time: The efficient drying process significantly reduces the drying time required.
Simple structure and small footprint: The design of the air dryer makes it easy to build and maintain.
Large processing capacity and high thermal efficiency: especially when drying unbound water, the thermal efficiency can reach 60%.
2. Application range of sawdust dryer
Sawdust dryers are used in a wide range of industries, including but not limited to:
Agricultural cellulose materials drying: such as corn straw, soybean straw, cotton straw and other straw drying.
Building materials industry: Sawdust as a soilless cultivation substrate, mushroom pile material and other applications in building materials.
Environmental protection and resource recovery: By drying, sawdust can be used as an organic fertilizer, contributing to the sustainable development of agricultural production.
3. The role of sawdust dryer in wood pellet production line
Sawdust dryer plays a vital role in the pellet production line, mainly reflected in the following aspects:
Continuous production: Through automatic control, continuous drying of sawdust can be achieved to improve the overall production efficiency.
Quality control: Precise temperature control and air dispersion ensure the uniformity of the drying process, thus ensuring product quality.
Energy saving and environmental protection: The design of sawdust dryer focuses on energy saving and environmental protection:
Efficient heat utilization: Maximize heat utilization by optimizing hot air flow path and material distribution.
Reduced energy consumption: The efficient drying process and simplified equipment structure help to reduce energy consumption and reduce production costs
