Hur man gör kolbriketter från sågspån i Kenya

In the recent past, the presence of natural charcoal is diminishing. But its demand has been high while the supply is limited. Partly because of diminished forests and the desire to conserve the trees. As a result, kolbrikettframställning is becoming popular today. And starting a charcoal briquette business has been profitable project in many countries, like South Africa, Uganda, Kenya, etc.. För detta, on 19th April 2024, we received a charcoal briquette making customer from Kenya. This client wanted to make charcoal briquette from sawdust. But he didn’t know what the production process is. The following are the detailed information in this case:

Why Is Sawdust Charcoal Briquette Making Popular in Kenya?

Kenya has long relied on traditional wood charcoal for cooking and heating, but with increasing deforestation and the rising cost of fuel, the search for alternative energy sources has become urgent. De senaste åren, producing charcoal briquettes from sawdust has gained popularity across the country. This eco-friendly solution not only reduces waste but also provides a sustainable source of income and energy for local communities.

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

Quality Requirements for Sawdust

The quality of sawdust has a direct impact on the strength, burning efficiency, and appearance of briquettes. Clean and uniform sawdust leads to higher carbonization efficiency and better compression during molding. The raw material should be free from paint, varnish, or chemical residues, as these can produce toxic gases during combustion. Finer particles are preferred because they fill molds evenly and bind more tightly under pressure. Choosing pure, uncontaminated sawdust ensures that the final briquettes are safe, luktfri, and environmentally friendly.

How to Control the Moisture Content of Sawdust

sawdust dryer for charcoal briquettes making

Moisture control is one of the most critical factors in briquette production. The ideal moisture content of sawdust is between 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.

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.

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.

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.

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.

What is the Advantage of Making Sawdust Charcoal Briquette?

Slutligen, customer from Kenya prepared to make sågspån charcoal briquette for a lone time. But he was worried that the profit would not be as good as selling natural sawdust charcoal. We explained to him the advantages of processing sawdust charcoal briquette.

Bästa 3 Carbonization Machines for Sawdust Charcoal Briquettes Making

After discussing the process, the Kenyan customer wanted to know which carbonization furnace is the most suitable for producing sawdust charcoal.

sawdust hoisting carbonization machine

Hyssande förkolningsmaskin

De hoisting carbonization furnace includes an electric hoist. Med den elektriska hissen, det kan lätt lyfta den inre tanken, som sparar arbetskostnader. Och varje ugn är utrustad med 3 inre tankar. Its carbonizing time is 8-12 timmar för att säkerställa den goda kvaliteten på träkol. Efter att en tank med material är färdig förkolning, du kan lyfta ut den i lyften och sedan sätta en annan tank med material för förkolning.

Horisontell karboniseringsugn

Horisontell förkolningsmaskin adopts a horizontal design to reduce machine height. Så det är bekvämare att ladda råvaror. And it also includes a smoke recycle system. Smoke generated in the carbonizing process enters the purifier and then be ignited for heating the furnace. Vad mer är, it produces charcoal by batch, carbonizing time 8-10 timme, vattenkylningstid 2-3 timme, air cooling 6-8 timme.

sawdust horizontal carbonization machine
sawdust continuous carbonization machine

Continuous carbonization equipment

Continuous carbonization furnace is suitable for charring the biomass materials which are in small pieces. When you use this machine for producing charcoal, we suggest the size of materials not bigger than 50mm. Though the carbonization rotary kiln has the function of drying, we don’t suggest carbonizing the wet materials directly, it will affect the carbonizing efficiency and charcoal quality. So it is better that make sure the moisture of materials is less than 30%.
