Why bamboo charcoal made by charcoal making machine is so expensive?

We all know that nearly all the biomass materials like peanut shell, coconut shell, sawdust, 籾殻, jute stem, paddy straw, sugarcane bagasse そして 竹 even the municipal solid wastes can be carbonized for charcoal. And the final charcoal can also be further processed with BBQ charcoal, shisha charcoal or hookah charcoal and other kinds of charcoal briquettes. But among all these charcoal, why bamboo charcoal is so popular even though it is costly?

What is bamboo charcoal from charcoal machine?

Here are some reasons for explaining this phenomenon that bamboo charcoal made by charcoal making machine is so expensive. Bamboo can be carbonized by the 炭化炉 directly. There are mainly two kinds of charcoal machines can be selected when to make bamboo charcoal. The first one is the 連続炭化炉 which can carbonize the bamboo chips with the diameter less than 10mm into charcoal within 20 minutes. For this carbonization process, the bamboo should be crushed into pieces firstly by the 木材粉砕機.

The other kind of charcoal making machine for sale is the airflow hoisting carbonization furnace as well as the self-ignition carbonization furnace, which can carbonize the bamboo directly without crushing. But considering the carbonization ratio, we should pay attention to the moisture content of the bamboo. If the moisture content is too big, the carbonization rate will be low and the charcoal quality will be not so good, especially for the fresh bamboo. The carbonization time in these two carbonization machines is usually 7-8 hours, and their output is very big.

The main advantages of the bamboo charcoal of charcoal making machine:

1. Bamboo charcoal is rich in minerals 

Bamboo is rich in potassium, sodium, calcium, magnesium and other minerals that are soluble in water. After burning bamboo charcoal in the carbonization furnace, minerals three times more than charcoal will be concentrated in bamboo charcoal. When 竹炭 is used to boil water, cook rice, brew tea, or brew coffee, these minerals will dissolve into the water.

2. Bamboo charcoal has superior adsorption capacity

The pores inside bamboo charcoal are widely distributed, and the surface area per gram of bamboo charcoal is as high as 300 M square, which is 3-5 times that of charcoal. These pores with large pore size have superior adsorption capacity and can absorb harmful substances such as chloride, sulfide, and formaldehyde, as well as odor and odor. When the bamboo charcoal is placed in water, fine impurities such as chloride ions and tea scale can be adsorbed to purify the water.
