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. The production of rice husk charcoal is a low-cost and high-yield business.

Rice husk charcoal

There are two ways to make charcoal from rice husks, one is to directly carbonize it into charcoal through a carbonization furnace, and the other is to first make a shaped rod and then carbonize it into charcoal. Here we will introduce these two methods separately.

Two methods to make rice husk charcoal

Carbonize rice husk to charcoal directly

There are two types of carbonization, one is carbonization by a self-made charcoal kiln, and the other is carbonization by machines. As you know, we are a professional charcoal equipment manufacturer, so here we focus on the production of rice husk charcoal by machine. In addition to the cost of the carbonization furnace is higher than the self-made carbon cellar, other aspects such as the charcoal quality, output, flue gas treatment, etc., the carbonization machine win perfectly.

Continuous charbonization furnace for making rice husk charcoal

In theory, all carbonization furnaces can be used to carbonize rice husks. In comparison, we recommend continuous carbonization furnaces. If you know about continuous carbonization, you know that this machine is suitable for carbonizing materials less than 5cm, and the material humidity needs to be less than 20%. The rice husk fully meets the requirements.

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.

Make rice husk into briquettes first and then carbonize

Rice husk is rich in cellulose and lignin, so it can be made into briquettes with a briquette-making machine. Due to the small size of the rice husk, it does not need to be crushed and can be used directly to make rods. But it should be noted that the moisture content must be controlled below 12%.

To carbonize the rice husk briquettes into charcoal, we suggest the airflow carbonization furnace.
