Raw materials of continuous carbonization furnace

Different from the hard materials processed by the hoist carbonization furnace and the horizontal carbonizing furnace, the materials carbonized by the continuous carbonization function have different requirements. The materials need to be small and thin, whose size should be under 10 centimeters. Peanut shells, plants, bark, straw, walnut shells, coconut shells, palm shells, sawdust, and other carbon-containing wood materials are all available.

The humidity of the raw materials should be under 20%, if not, they should be removed from water by a biomass rotary dryer. Dry distillation and anaerobic carbonization are carried out under high-temperature conditions in the carbonization machine. The carbonization furnace has a high carbonization rate. It is a piece of ideal equipment for charcoal processing plants.

Structures of sawdust charcoal making machine

The continuous carbonization furnace mainly includes spiral feeding, flat feeding, host, condensing discharge, flame head, combustion pool, purification equipment, power distribution cabinet, etc. The material needs to pass through the preheating zone, high-temperature carbonization zone, and cooling zone.

How to carbonize rice husk in a continuous carbonization furnace?

After turning on the machine, use Liquefied petroleum gas (LPG) to ignite the machine. The machine needs to be preheated for about 1 hour, and 20-30kg of LPG is required to ignite one time. (The whole process only needs to ignite the LPG once)

The preheating is completed when the preheating temperature reaches 280°-330°, and the raw materials are put in. When the raw material is coconut husk, the material is discharged when the temperature in the continuous carbonization furnace is 330 degrees, and the raw material is lighter raw materials such as palm husk, rice husk, and wood chips. When the temperature in the furnace reaches 280°, the material is discharged.

Ignite the combustion chamber. After carbonization for 10-20 minutes, observe whether hot gas is generated in the combustion pool. If flammable gas is generated, ignite the gas to burn the combustion chamber. Then turn off the burner and no longer use LPG.

It takes 20 minutes for a round of carbonization, after which the material can be re-cut to start a new round of carbonization.

Cooling is required when discharging. The carbonization furnace is equipped with a double-layer condenser, the carbonized raw material is discharged from the inside, and the outside is filled with circulating water for cooling.

The continuous carbonization furnace is named according to the diameter of the furnace. The larger the diameter, the more raw materials that can be carbonized. Among them, the output and price of WD-CF1000 model are relatively moderate, which is more popular with customers.

Features of sawdust charcoal making machine

1. Characteristics of continuous feeding

The carbonization furnace realizes the production process of continuous feeding, continuous carbonization, and continuous carbon output, breaking the problem that traditional carbonization equipment cannot be continuously carbonized, and greatly improving production efficiency.

2. High degree of intelligence

This equipment adopts an intelligent control system, which saves labor, and has taken a leap forward from the original hand-crafted workshop to a high-efficiency, automated, and intelligent development.

3. Low carbon and environmental protection

The carbonization furnace has professional smoke removal equipment during the working process, which will not pollute the internal environment of the factory. After burning, there is less residual ash, using liquefied gas and combustible gas to generate heat, without cutting trees, and protecting the environment.

4. Automatic collection of by-products

In the carbonization process, the equipment can automatically collect tar, wood vinegar and combustible gas, realizing the efficient and comprehensive utilization of renewable energy.

5. Advantages of finished products

The finished product does not contain chemical substances, is non-toxic, odorless, and pollution-free. In addition, the finished product has low water content, within 5%, and a long burning time.

FAQs of continuous carbonization furnace

What is the heating source of the sawdust charcoal-making machine?

The source of heat is liquefied gas. Only 15-20kg of liquefied gas is needed for one round, and combustible gas will be produced after 1-1.5 hours of combustion. The subsequent production process no longer needs liquefied gas, so customers are advised to use LPG as the source of heat.vaporizer of LPGthe heating source

Is the material that can be carbonized by the carbonization furnace only biomass raw materials?

In addition to biomass, the continuous carbonization furnace can process raw materials such as tin foil, aluminum foil, cans, household garbage, plastics, electronic waste, etc., but the size cannot exceed ten centimeters.
