Rice husk charcoal is formed by insufficient combustion of rice husk when heated to below its ignition temperature. Rice husk is the outermost part of the rice seed which is a hard layer and a waste material from rice milling. Therefore, the raw materials for producing rice husk charcoal are abundant and low in cost. Making rice husk charcoal is a low-cost and high-yield business.

Rice husk charcoal

There are two ways of making charcoal from rice husk, one is directly carbonizing it into charcoal through a carbonization furnace, then compressing the rice husk charcoal into briquettes. The other is to compress rice husk into briquettes first by the rice husk briquette machine, then carbonize the rice husk briquettes into charcoal. Here we will introduce these two rice husk charcoal-making processes separately.

Two different processses of making rice husk charcoal

Carbonize rice husk to charcoal firstly

There are two ways of carbonization, one is carbonization by a traditional charcoal kiln, and another is carbonization by machines. Here we focus on the production of rice husk charcoal by machines.

Compared with the traditional carbon cellar, the carbonization machine has the advantages of less labor intensity, shorter carbonizing time, smokeless, higher charcoal yield.

We have different types of carbonization furnaces that can be used for carbonizing rice husks. For small or medium-scale charcoal production, the hoist type and horizontal type carbonization furnace are recommended. For the large capacity of rice husk charcoal production, you can choose the continuous carbonization machine (rotary carbonizer).

Rice husk charcoal uses

  1. In industry, rice husk charcoal can be used as a thermal insulation material for steel production, and it can also be used as a raw material for steelmaking auxiliary materials.
  2. In agriculture, it can be used as fertilizer and soil improvement for the cultivation of vegetables, flowers, seedlings, fruit trees, and other crops.
  3. In daily life, it can be used as clean energy for cooking and heating. Since the rice husk charcoal is directly carbonized into a pulverized state, it needs to be further shaped into briquettes for ease of use. For the detailed steps of making rice husk charcoal briquettes, please refer to another article.

How to make rice husk charcoal briquettes

After rice husk is carbonized into charcoal, we need to use a charcoal briquette machine to make charcoal briquettes. We have 4 types of charcoal briquette machines for making different shapes of briquettes from rice husk charcoal.

Make rice husk into briquettes first and then carbonize rice husk briquettes into charcoal

rice husk briquettes

Rice husk is rich in cellulose and lignin, so it can be made into briquettes by a rice husk briquette machine. Due to the small size of the rice husk, it does not need to be crushed and can be used directly to make briquettes. Therefore, the process of making charcoal from rice husks is the same as that of making charcoal from sawdust.

The following is a detailed article on charcoal production from sawdust, the whole process is also applicable to rice husks.
