1. Preparing Raw Materials for Sawdust Charcoal:
The first crucial step in manufacturing sawdust charcoal involves collecting sawdust from various wood sources, notably acacia, eucalyptus, ironwood, and longan trees, typically from specialized trade villages in Vietnam. The collected sawdust undergoes fermentation for approximately 10 to 15 days to soften it, facilitating subsequent processing. This prepared sawdust must then be dried meticulously, reducing its moisture content to a maximum of 10%, ensuring optimal conditions for high-quality eco-friendly charcoal production.
2. Producing Sawdust Briquettes:
Once the sawdust is adequately prepared, it is compressed using specialized briquetting machines. These machines mold the sawdust into high-density briquettes known as bio-wood, essential intermediate products in creating premium ogatan charcoal. These briquettes typically measure about 450mm in length and 50mm in diameter. Quality is paramount in this stage, as superior briquettes without surface cracks are necessary for achieving premium quality charcoal from Vietnam.

3. Carbonization of Sawdust Briquettes Charcoal:
In this phase, the sawdust briquettes undergo controlled carbonization within specially designed kilns. This process is essential to convert the briquettes into high-quality sawdust briquettes charcoal.
– Phases of Sawdust Briquettes:
3.1.Steaming Phase (Days 1-2):
– White smoke emerges as moisture evaporates
– Kiln temperature gradually reaches around 500oC
3.2.Drying Phase (Days 3-4):
– Appearance of yellow smoke, transitioning to grey
– Temperature increase to approximately 550-600oC
3.3. Carbonization Phase (Days 5-8):
– Green smoke indicates effective carbonization
– Crucial temperature ranges between 1000-1200oC to achieve the premium quality BBQ charcoal. Air vents are strategicall openes to ele vate temperatures swiftly.
3.4. Cooling Phase (Days 8-15):
– Kilns are sealed to facilitate gradual cooling over 7-8 days, stabilizing the charcoal structure and composition.
4. Final Product and Packing:
– The finish sawdust charcoal features a reduced diameter typically between 38-40mm, due to intense carbonization. The resultant charcoal is highly valued for its clean-burning qualities, with smokeless, no chemicals and high carbon content of around 88-90%, ideal for use in the best charcoal grill setups.
– Finally, sawdust charcoal is carefully packinto cartons, ensuring its integrity during transportation, before being loaded into containers ready for export.
