charcoal from straw

Straw to Charcoal Machine

Straw is also a kind of biomass material which usually includes cornstalk, wheat-straw. etc. In the past, we always regarded straw as useless waste which only could be used to feed animals. However, with the increasing innovation of technology, the straw waste can be used to produce valuable materials. For example, we can extract charcoal from straw through the related technical equipment, straw charcoal machine.

Beston straw to charcoal making machine has many outstanding performances in many aspects. Firstly, the raw materials: our biochar machine mainly focus on the process of biomass waste and sludge, which can thoroughly realize the resources recycling. What’s more, the straw carbonization machine can not only process one material, but also plays an important role in the treatment of various biomass materials such as sawdust, coconut shell, rice hull and etc., which can be called single machine with wide applications

Unique features of Beston straw charcoal machine for sale

No.1 Efficiency of environmental protection

Beston straw charcoal making plant is also a kind of machine to protect the environment. The tail gas generated in the production process will be recycled by the furnace to provide heat, which can fully utilize the energy. We can sure that there is no harmful gas generated, and it also can achieve the EU emission standard.

No.2 High value of final products

The final products from straw carbonization mainly include: charcoal, combustible gas, tar and wood vinegar. All of the products have wide applications, which can not only create economic benefits but also can environmental interests.

Straw charcoal, with the high heat value, can be used as fuel directly, and we always use it for BBQ, which is more environmental than coal;

Combustible gas, in fact, is the tail gas, which can be recovered directly in the process or collected to be applied in other places as fuel;

As for the tar and wood vinegar, they also make a great contribution to our life: for example, the chemical fertilizer of agriculture always use them as raw material or additive.

Brief introduction of related technology in the process of making straw charcoal

Firstly, the heating system: Beston straw to charcoal plant has introduced the unique carbonization furnace which consists of inner and outer cylinder, so when the machine is running, the raw material should have a dry pre-treatment and then is conveyed to the outer cylinder. Because the outer cylinder has been surrounded by high temperature directly in the production process, and the temperature can reach 800 degree centigrade, we adopt the furnace made of unique materials, which can extend the service life of the machine. The temperature of outer cylinder can get to 700 degree centigrade after the long-term operation; after the dry pre-treament, straw will begin carbonizing. And the carbonizing furnace also has introduced the variable frequency motor to control the temperature and time in the carbonization process.

Secondly, sealing system of straw carbonation equipment: in the process of carbonization, we are aimed to make the straw carbonized by high temperature heating, so it does not allow excessive oxygen to participate in the reaction. Thus, the sealing of furnace plays an important part in the whole process. Our charcoal machine has applied the seal type of rusty steel shrapnel which can adjust the axial displacement of cylinder and the circumferential swell, caused by the thermal deformation. In addition, the elastic material with high temperature resistance and high wear resistance is always in close contact with the cylinder, so as to achieve good sealing effect.

Thirdly, cooling system: generally, the temperature of charcoal often keeps about 200 degree centigrade after baked, so it is dangerous to discharge directly. Therefore, we will not discharge the charcoal until the temperature is lower than 30 degree centigrade. Beyond that, our biomass carbonization machine has used the unique cooling discharge system which has multiple layers screw cooling system, so that the cooling water can be constantly recycled in the water pump to reduce the temperature of charcoal.
