I det senaste förflutna, förekomsten av naturligt träkol minskar. Men efterfrågan har varit hög samtidigt som utbudet är begränsat. Dels på grund av minskad skog och viljan att bevara träden. Som ett resultat, kolbrikettframställning blir populärt idag. Och att starta en kolbrikettverksamhet har varit ett lönsamt projekt i många länder, som Sydafrika, Uganda, Kenya, etc.. För detta, den 19 april 2024, vi fick en kund för tillverkning av träkolsbriketter från Kenya. Den här kunden ville göra träkolsbrikett av sågspån. Men han visste inte vad produktionsprocessen är. Följande är den detaljerade informationen i detta fall:

Varför blir sågspånkolbriketter populär i Kenya?

Kenya har länge förlitat sig på traditionellt träkol för matlagning och uppvärmning, men med ökande avskogning och stigande bränslekostnader, sökandet efter alternativa energikällor har blivit brådskande. De senaste åren, att tillverka träkolsbriketter av sågspån har vunnit popularitet över hela landet. Denna miljövänliga lösning minskar inte bara avfallet utan ger också en hållbar inkomstkälla och energi för lokalsamhällen.

Kenyas möbel- och träindustri genererar stora mängder sågspån varje dag, varav de flesta brukade brännas eller dumpas. Genom att omvandla detta avfall till träkolsbriketter, tillverkare kan förvandla lågvärdiga restprodukter till högvärdigt bränsle. Denna process hjälper till att minska miljöföroreningar och främjar cirkulär ekonomi.

The Kenyan government encourages renewable energy initiatives and sustainable waste management. Projects that convert agricultural and wood waste into briquettes align with national clean energy goals and often receive support from NGOs and local authorities. This favorable policy environment makes sawdust charcoal production even more attractive to entrepreneurs.

With urban populations expanding and traditional charcoal prices increasing, demand for cheaper and cleaner fuel is growing rapidly. Sawdust charcoal briquettes burn longer, produce less smoke, and are more affordable for households, restaurants, and small industries-making them an ideal alternative in both rural and urban markets.

What Kind of Sawdust Is Used for Making Briquettes in Kenya?

Quality Requirements for Sawdust

Kvaliteten på sågspån har en direkt inverkan på styrkan, förbränningseffektivitet, och utseende av briketter. Rent och jämnt sågspån leder till högre förkolningseffektivitet och bättre kompression under formningen. Råvaran ska vara fri från färg, lack, eller kemikalierester, eftersom dessa kan producera giftiga gaser vid förbränning. Finare partiklar är att föredra eftersom de fyller formar jämnt och binder tätare under tryck. Att välja ren, oförorenat sågspån säkerställer att de slutliga briketterna är säkra, luktfri, och miljövänligt.

Hur man kontrollerar fukthalten i sågspån

Fuktkontroll är en av de mest kritiska faktorerna vid brikettproduktion. Den ideala fukthalten i sågspån är mellan 8% och 12%. Om materialet är för blött, the briquettes will not hold their shape and will take longer to dry after pressing. Å andra sidan, overly dry sawdust lacks flexibility and reduces the bonding strength between particles.

To achieve the right balance, producers often dry sawdust under the sun or use a rotary drum dryer for faster and more consistent results. During rainy seasons, storing sawdust under a covered shed and using airflow dryers helps prevent moisture absorption. Regularly checking the material’s moisture level before carbonization or briquetting ensures stable production and high-quality briquettes.

What is the Process of Making Biochar Briquette from Sawdust?

This Kenyans customer wanted to know the process of producing sawdust biochar briquette. I allmänhet, det finns 4 steps in the production of sawdust charcoal briquette.

Crushing wood into sawdust

If your material is wood, du kan använda hammare to make wood into sawdust. But if your material is sawdust, you can directly ignore this step. And when you want to prepare high quality sawdust charcoal briquette, you can also crush sawdust into about 5-millimeter size.

Drying sawdust

Then you need a drying process. If the water content exceeds the empirical upper limit, the temperature will rise and the volume will suddenly expand. För detta, it is easy to cause an explosion. Then if the moisture content is too low, it will be difficult to shape. So you can use a dryer to reduce the moisture content to about half (to about 15%) the level required for briquettes formation.

Sawdust briquette making

Compress the briquette machine under high pressure and temperatures in a process known as briquetting. During this process there is self-bonding which involves thermoplastic flow of the biomass. Lignin content is formed naturally inside the biomass machine due to high pressure and temperatures, and it is liberated. It serves as glue, binding and compressing the biomass to form high-density briquettes. För detta, we recommend you kolextruder.

Carbonizing sawdust briquette

After briquetting sawdust, you can put them into carbonization furnace. According to their rod shape, we recommend you two carbonization machines. Hoisting carbonization machine and batch type carbonization furnace. You can choose them according to your capacity.
