Carbonization plants

Bio-charcoal (rice husk charcoal) production plants

These plants automatically and continuously carbonize the rice husks generated as a by-product of rice cultivation, creating bio-charcoal (rice husk charcoal). 
We can also purchase the bio-charcoal produced for a fee. 
[ Raw materials ]
〇 Only rice husks dried to 15% or less moisture are used. （Husks that have become wet in outdoor storage cannot be carbonized)
[ Properties ]
◆ Continuous carbonization method
Because we use a patented continuous fixed floor carbonization system, it does not produce the kind of black smoke or odor of controlled burning or batch methods. 
◆ Service life
There are few failures, and the parts are easy to replace. We have more than 40 years of experience in operation. 
◆ Using the exhaust heat
The thermal energy generated when producing bio-charcoal can be put to use in a variety of ways (hot air, hot water, steam boiler power generation, etc.)

Charcoal chip production plants

These chip difficult to process materials such as pruned branches and the wood from forest thinning, then carbonize them. Charcoal chips are designated by Cabinet Order as a soil improvement material. 
[ Carbonizable materials ]
〇High-moisture wood chips　〇Brewer's spent grain　〇Coffee grounds　〇Debris from scallions and onions 〇Tofu residue　〇Fruit waste 〇Other food leftovers 〇Compost
[ Properties ]
◆ Charcoal chips
The chipped wood is carbonized as it is, producing highly porous charcoal. 
◆ Various types of wood can be carbonized
There is no limit to the raw materials that can be used: even wood with high moisture such as wood chips, bamboo chips, and pruned branch chips can be carbonized. 
◆ Options
・Extraction of wood vinegar
・Processing into pellets
・Multipurpose use of thermal energy during carbonization

High-moisture material carbonization devices

These are devices for carbonizing raw materials with high moisture content. 
These enable the carbonization of brewer's spent grain, coffee grounds, fruit and vegetable waste undried wood chips, compost, manure, and various other kinds of food waste. 
[ Carbonizable materials ]
〇High-moisture content wood chips　〇Brewer's spent grain　〇Coffee grounds　〇Tofu residue　〇Debris from scallions and onions　〇Fruit waste　〇Compost, etc.
[ Properties ]
◆No smoke or odor
Efficiently processes the odors generated during drying and grinding 
◆Designed to accommodate the raw materials used
The equipment is designed and developed after conducting carbonization tests and ascertaining the properties of the raw materials. This allows carbonization tailored to the materials themselves. 
◆Use of exhaust heat
The heat produced during carbonization is used to dry the raw materials.

Rice husk grinding and composting plants

Grinding the rice husks improves their properties, allowing a wider range of applications and making it easier to recycle. It can also be used as a moisture control agent when composting manure and garbage, or as litter material for livestock. It is also possible to create compost through fermentation using rice husks alone.

“Double Press” Rice husk compression and water swelling device.

Rubbing the husks against each other and breaking down their structure reduces them to a fine powder. Because they are pressurized after adding water, the ground rice husks acquire a high degree of water absorbency. 
Because it grinds the husks against each other, the process does not cause wear to the machine. This, and the use of special steel parts, gives it excellent durability. The expendable parts (screw cutters, etc.) can be repaired by welding, allowing running costs to be kept under control.

Puffy husks

By forcibly compressing and pressurizing the rice husks together, they are ground against each other. Then, adding water breaks down the structure of the husks, turning the ground husks into a soft, puffy powder. 
By applying a particle size control panel (optional), you can change the size of the particles to which the husks are ground. 
The machine's compact design allows you to use free space effectively. The expendable parts are cartridge-based, so they can be easily replaced.

Rice husk fuel production systems

These are systems that can use the rice husks produced by the local area as fuel. Solidifying the husks allows cuts in transportation costs. 
These systems provide very clean energy — using biomass-derived raw materials leads to reductions in carbon dioxide.

"Fire Husk Machine" Rice husk molding machine

This machine compresses rice husks to 1/10 of their original size and processes them into rods. Solidifying the husks keeps transportation costs under control and turns them into a shape that it easy to use as fuel. They can also be processed into a curled shape as the application requires. This curled shape compresses the husks to 1/5 of their original size.

"Fire Husk Burner" Rice husk heater

Rice husk fuel rods ("fire husks") are placed into the upper door of the machine. It burns continuously for about 10 hours, maintaining stable heat output. As it uses a gasification combustion method, the heater produces a clean exhaust. To remove the ash, just open the front door and scrape it out. Day-to-day maintenance is also easy. You can choose either an air or water heat exchanger to suit the particular use case. It can be used for house heating, public facilities, indoor heating for meeting places, and more.
