The final production line:

1.Introduction of Charcoal Carbonization Stove:

The airflow charcoal manufacturing oven is our new invent, which is also combined type. The charcoal can be hoisted outside, in this way the cooling time can be reduced much, thus, the productive efficiency increases a lot. It is the ideal choice for mass production of charcoal.
This type of furnace adopts the structure of unique air storage chamber, to fully reuse the smoke produced during the process of carbonization. And 60% of the redundant smoke can be used in drying and carbonizing, saving much fuel during the whole process, and increasing the enterprise revenue.

Raw materials of wood charcoal carbonization furnace : 

1. Tree branches whose diameter is more than 30mm.
2. Some nut shells, such coconut shell, walnut shell, etc.
3. Biomass briquettes made from sawdust, small agriculture wastes.

Square type:

Round type:

2.The main parts of Charcoal Carbonization Stove:

(1) Outer stove:
Includes heating room (for heating the inner stove), furnace body and heat-keeping layer (it is made of the heat insulating material)
(2) Inner stove:
Consist of the stove tank body and the sealed top cap. Both of them are made of the heat resistance thermal steel, three inner stove can be stacked together for saving space and shipping cost.
(3) Smoking recycle tube.
During the process of carbonizing, there will be some smoke.( can be burning) the smoke can be collected and returned to the furnace.
(4) Purification tank.
This system is consisting of purification tank and the exhaust-heated cycle pipe.
(5) Hoisting equipment.
It include the steel hoisting frame and the E-hoist .And it is easy for loading and unloading the stove.

3.Parameter of Charcoal Carbonization Stove:

PS 1: Load 2.5tons machine-made briquettes, 8hours will get 1000kg machine-made charcoal.
PS 2: Load 2tons natural wood, 8-10hours will get 600kg-800kg natural charcoal.
PS 3: Normally it takes 8-10hours. Maybe longger for fresh wood to remove moisture.
PS 4: Heat value: 5500-7000KCAL / KG
PS 5: Raw material: Machine-made charcoal, wood ,coconut shell, wood briquette, bamboo, almond shell, plam shell,
PS 6: Operation: one people one shift ( one day two shift)
PS 7: Energy consumption 20-30kg firewood or 15kg liquid gas.

4.How to produce charcoal? It divides into three processes:

(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.

5.Gas purifier:

It is used to eliminate the smoke produced by the wood charcoal carbonization stove, and also it can turn the smoke and some other soluble organic maters into fuel, or some other energy, it is really an environment protect and energy saving device designed and manufactured by our technicists.

6.Our project:

1. Established in 1980s, our company covers an area of 100,000 square meters which includes 66,000 square meters of workshops. We have the most advanced technology, most strict process, from material purchase to the finished products, all strictly according to the national quality inspections standards.It mainly specilize in charcoal making machine, sawdust briquette machine,briquette machine,powder making machine,extruder machine, BBQ machine,honeycomb briquette machine,carbonization furnace,heat pump dryer and so on. 

2. As manufactures, we have more than 30 years of experience, our products all achieved patent certificates, and our company has many times achieved the title of honer: " Observe Contract and Keep Promise" " Quality Trustworthy Product" "Good After-sales Service Reputation", etc.

Characteristics of air flow carbonization furnace:                                        1.New type of carbonization equipment, production higher than general furnace, fast speed, high carbon, simple operation

2.With smoke purification device, can store tar, no leakage, long service life;

3.Suitable for wood, logs, mechanism charcoal, nut shell, bamboo, etc, different shaps biomass raw material.

Advantages:                                                                                                          

No polution: there are two reasons : the frog and the gas flow will be recycle from the smoke recycle device and use for heating the kiln again. We install a special device that can use the liquid gas as the energy to heating the carbonization kiln, and it will not produce any smoke. 

Carbonize time more shorter: This type have three inner stove, when one inner stove finished (6- 8hours ) , use the hoist tools lift the inner stove out let it cooled naturally, at the same time, lift the other one in , 3 inner stove can work continuously. 24 hours can carbonizing 3-4 inner stove.

Easy operate: One people can control 2-3set, but need the crane for help; When one inner stove have been finished carbonization, use the hoisting tools hoist the inner stove from the outer stove, then let the inner stove natural cooling, at the same time, put another inner stove into the outer stove, which will save a lot of cooling time, so the productivity effect increase a lot.
