Environmental friendly mini furnace/sawdust carbonization furnace/charcoal production for Smokeless Continuous Carbonization

Flow Chart of the Complete Line

Step 1- Crushing: crush the raw materials into small pieces (3-5mm) by wood crusher/Hammer Mill;

Raw material:

Almost all type of Agro-Forestry waste can be used, including: wood chips, maize stalks, soybean stalks, broomcorn stalks, cotton stalks, rape stalks, peanut plants, sunflower stalks, bamboo saw dust, bagasse agro-forestry wastes, such as sawdust, wood chips, branches, crop stalks, sugarcane residue, coffee husk, paddy straw, sunflower stalk, cotton stalks, bamboo dust, palm husk, soybeans husk, tea waste, etc.

Step 2- Drying: dry the crushed materials by flash dryer to reduce the crushed material's moisture content below 8-12%; PS1: if the moisture of raw material is 8-12%, you can ignore the drying process

Step 3- Briquetting: Put the dried materials into the briquette machine to make sawdust briquettes. This stick is 45-80mm in diameter, occurs in the hollow quadrangular or hexagonal cylinder or hollow hexagonal with a 15-20mm hole through the body.

Final Briquettes

♦ square, round, hexagonal, pentagon(with/without edge)
♦ Hollow
♦ Stick shape
♦ Diameter: 50-80mm
♦ Inside diameter: 15-20mm
♦ Length: 20-50mm
♦ Weight of one briquette: 1kg
♦ Specific gravity: 1200—1300kg/m3 
♦ Calorific value:4000-4800kcal/kg

PS1:You can also carbonize the material without crushing and briquetting

 Step 4 - Carbonization: Put finished sawdust briquettes into the charcoal making machine to convert the sawdust briquettes into charcoal briquettes(5500-7000KCAL / KG)

Load 2.5tons machine-made briquettes, 8hours will get 1000kg machine-made charcoal. Load 2tons natural wood, 8-10hours will get 600kg-800kg natural charcoal.
Normally it takes 8-10hours. If your natural wood is fresh, it takes long time to remove moisture of wood, therefore, carbonization time is longer.

How to produce charcoal? 
1. Heat
After sealing work, use wooden wastes or gas to heat furnace. Primarily, 10 minutes big fire to burn, when the temperature reaches 90 degrees centigrade, turn to use slow fire to heat. It takes 80-120minutes for this process to reduce water vapor from your materials.

2. Pyrolyse
Keep heating, when the temperature reaches 180-235 degrees centigrade for 3-5hours, it will produce gas from this process. Reuse this gas as fuel to heat. The whole process is about 8hours. When the temperature reach highest and it reduces, the dry distillation process will finished.

3. Cooling
Hang the Inner pot outside, and seal the pipes of cover. Let it cool naturally. Cooling time is longer, the quality of charcoal is good. When the temperature lowers than 50 degree, you can take charcoal out. Otherwise, the charcoal will burn again when met oxygen of air.

Wide Use

♦ Charcoal in industry: It is mainly used in combining carbon of industrial materials, metallurgy, and the carburizing carbon of chemical industry.

♦ Charcoal in agriculture and animal husbandry: It can raise the soil temperature, maintain soil moisture, mitigate the organic fertilizers and improve soil PH.

♦ Charcoal in life: People often use charcoal heating, barbecue, as well as the fuel used to the tea and tobacco drying.

 Clients Visiting

♦>> What materials do you use to dry ?
You can use almost all the biomass materials.
♦>> What is the max moisture of your material ?
Our machine can dry biomass materials between 60% and 70%.
♦>>What is the temperature?  230℃
♦>>What is the carbonization rate ? can reach 99%. 
♦>>Could you offer complete briquette machine production line ?
Yes, we will allocate suitable production line, according to your special requirement, such as crusher, conveyor, dryer, briquette machine, etc.
♦>>Where is your factory located? How do I get there ?
We are located in Gongyi city, Henan province, middle of China; The nearest airport is XINZHENG International Airport, and the Airport Code is CGO
We will pick you up at airport or railway station. Welcome to visit our factory.
♦>>Installation time: 5-7days
♦>>What is capacity of your machine ?
One inner pot can load 2.5tons machine-made briquettes; 8hours will get one ton machine-made charcoal.
One Inner pot can load 2tons natural wood, 8-10hours will get 600kg-800kg natural charcoal.
Therefore, one furnace can get: 3tons machine-made charcoal, 1.8-2.5tons natural wood charcoal.
♦>>What is carbonization time ?
Usually, 8-10hours. If your natural wood is fresh, it takes long time to remove moisture of wood;

Therefore, carbonization time is longer.
♦>>When the charcoal is finished ?
There is no smoke and smoke is blue lucid, the process is finished.
♦>>How many times should we cool the charcoal ?
It takes 10-16hours. When the inner pot goes down to 50℃ or less, charcoal can be packaging and collecting.
♦>>Can we use the machine directly ?
Yes, start the machine, when temperature reach 320 degree, put your materials into hopper, you will get fuel briquette
♦>>Does this machine has spare parts ?
Yes, below is some parts of this machine, please check it. When you buy our machine, we will attach 1*propeller, 1*shaping pipe , 3* welding rods, 3* Heating rings
