How to make coconut shell charcoal using a drum-type kiln with controlled air supply

How to make coconut shell charcoal using a drum-type kiln with controlled air supply, Raw material coconut shell charcoal briquettes special requirements that must be met, among others, the charcoal must be clean, white ash, moisture content of 5%, maturity level is perfect and from coconut shell material that is old. To produce coconut shell charcoal is of good quality, the combustion process must be controlled. Burning coconut shells using a drum-type kiln with controlled air supply can produce high quality charcoal in accordance with the standards for the raw material of active charcoal. Cheap and simple, that's the main key of charcoal-making technology with controlled drum system, charcoal yield any results far above the traditional way.

How to make coconut shell charcoal using a drum-type kiln with controlled air supply

Design Tools
Materials used are drum former with a height of 90 cm and a diameter of 60 cm. Close the drum is separated (cut) from the body so that it can be opened and is closed. At the top of the hole made in the form of exhaust fumes from the chimney pipe material zinc with a height of 30 cm and a diameter of 10 cm. The top of the chimney is equipped with a cover that can be opened and closed. Agency perforated drum, diameter 13 mm. The air holes consisting of 3 rows, each row consisting of 4 holes, with the spacing between rows 30 cm. Thus the total number of holes there are 12 pieces.

Preparing Material Shell
Charred shell will preferably in air dry state. Water content not more than 20%. The goal is that the combustion process can go faster and do not produce much smoke that could disturb the neighborhood. That the results of good quality charcoal, before it is processed coconut coir is cleaned from, soil, sand and other debris attached. The size and shape of the shell arranged in order to fill the drum as much as possible and produce charcoal that meet the required standard sizes. We recommend that most small shell size width 2.5 cm. If good arrangement, the drum can accommodate 90 kg of material, could also be.

Charging Material
Manufacture of charcoal with a controlled air supply system is basically not much different from the usual way of farmers and local artisans shell charcoal. However, there are some differences in working order, tools / kiln, and how to put out the fire. Working order manufacturing of coconut shell charcoal by means of a controlled air supply is as follows: 
(model LIPI - Balitka Manado dan BPTP Jambi)

• 7.5 kg of coconut shell inserted into the drum furnaces that has been available up to 1/4 of the drum parts. before it is inserted into the drum shell, a piece of wood and bamboo diameter of 10 cm length 1 m placed perpendicular in the center of the drum. Furthermore, the drum is filled shell, Thereafter, wood or bamboo rods withdrawn slowly, to form a hole in the center of the drum.

• Holes in the air handler drum kiln sealed, except for a hole in the bottom row are left open.

• Do the first combustion by turning coconut husks or other flammable materials

 • Once the fire is lit to perfection, is added into the drum shell slowly so that the fire was not extinguished until the drum is full (about 32 kg). The drum cover is installed, but the chimney at the top of the drum was left open.

• Smoke coming out of the chimney note; if the smoke coming out pretty much means the combustion process runs perfectly.
• From the air control hole bottom (line I) that is open, it can be seen burning shell have a perfect or not. If the shell has become embers, means burning shell at the bottom perfectly.

• Holes air control on the first line and the hole sealed on the second line is opened, then add coconut shell until the drum is full (about 12 kg) by opening the cover on the drum, then the drum is closed again.

• The process of opening and closing the air control hole made in line with the addition of coconut shell into the drum. The same way as above until the air control holes on the top row (there are five rows of holes).

• After the smoke coming out of the chimney is no longer concentrated, but more transparent / clear, all the air control hole and the hole closed chimney. Closure should really tight and certainly not leaking so in the drum into the vacuum. To ensure there are no leaks, all the manhole cover and the air control chimney holes patched with clay.

• Due to the vacuum in the drum, the fire is in the drum turns off by itself (about 1.5 hours after being closed).

• Cover the top of the drum can be opened after the temperature is cold enough (8-12 hours). Combustion products such as charcoal and then removed to cool. Charcoal that has been chilled in the filter to clean the ash and other impurities.

The yield of charcoal or the results obtained in this way is high. According to the Forest Products Research and Development research, which modify, yield of charcoal produced these tools range from 34-39% of the weight of dried coconut shells. Can be compared, for example, with a yield of charcoal made traditionally, only 25%. The high yield makes charcoal production, with the same material number is higher. The authoring technology can certainly be used as one of the attractive alternatives that could be developed in the domestic industry.
