What is the working principle of a sawdust charcoal machine?
Product Description
Core Mechanism: High-Temperature Oxygen-Deficient Carbonization and Decomposition
The core working principle of the Sawdust Charcoal Extruder Machine is "high-temperature oxygen-deficient pyrolysis." A heating device raises the furnace temperature to 400-600℃ while simultaneously isolating the wood chips (controlling oxygen content ≤5%). This allows moisture and volatiles (tar, methane, etc.) in the wood chips to gradually decompose and be released, retaining only fixed carbon components, ultimately forming loose charcoal powder or dense charcoal blocks. The entire process consists of four stages: drying, pyrolysis, carbonization, and cooling. No open flame combustion is used throughout, preventing the wood chips from completely oxidizing into ash.
Briquette Making Machine Synergistically: Laying the Foundation for Carbonization Raw Materials
The Sawdust Charcoal Making Machine is the core pre-processing equipment of the wood chip carbonization machine, and its working principle is directly adapted to carbonization requirements. The briquette making machine uses spiral extrusion and frictional heating (temperature 160-200℃) to compress loose wood chips into high-density cylindrical rods (wood chip rods). These rods rely on lignin self-bonding, eliminating the need for binders. This densified briquette material prevents loose sawdust from clumping and agglomerating during carbonization, ensuring uniform carbonization and reducing losses. It is over 30% more efficient than directly carbonizing loose sawdust.
The two work in tandem: a closed loop from sawdust to charcoal
The wood chip charcoal extruder and the wood chip carbonization machine form a complete processing loop: the briquetting machine first transforms fresh sawdust into dense wood chip briquettes, solving the problem of uneven carbonization of loose raw materials; the wood chip carbonization machine then carbonizes the briquettes at high temperatures, decomposing impurities and retaining carbon components; in some scenarios, the carbonized charcoal blocks can be further extruded by the briquetting machine (with the addition of a small amount of binder) to process into shaped charcoal, forming a complete process of "sawdust - wood chip briquettes - charcoal powder/blocks - shaped charcoal." The two processes complement each other and are indispensable.
