It makes medium-sized batches of biochar! 

• Dimensions are 1.2m(W) x1.2m(L) x 0.92m(H)
• Weighs 150kg with a volume of approximately 350 litres
• All cones are made from 3mm HW350 weathering steel with a dished bottom and central 2" drain for drainage. In other words, the kiln can be left outside or stored inside. 
• The cone finds a natural level for balancing during use (especially good for slight inclines/declines plus 2 brakes on the casters help steady the kiln) and is manually tilted/tipped over a pivot on the cradle for emptying. 
• Removable heavy duty solid rubber wheels on casters (2 with brakes) enable the 'Rolls' to freely move around different terrain/surfaces and can be rolled onto and off a standard trailer for remote burns. 
• For shipping/transportation, the 'Rolls' can roll onto a 1200x1200 pallet for A to B. 
• The 'Rolls' will be supplied with a galvanised 'Quad' (4 pieces) collapsible heat shield. 
• A drain is supplied with a standard 2" 316 stainless steel elbow welded at the cone base connected to a 1" (600mm) galvanised pipe and 1" ball valve. The 2" elbow also allows for other drain configurations. The drain can easily connect to 1" Ag line (commonly available in Australia). The Ag line can connect to an electric submersible water pump (powered by AC mains/battery with an AC port) at the bottom of a water-filled IBC for quenching the burn and draining the kiln after a burn (with the pump in reverse). Note that the ag line, pump, battery, IBC and water are not supplied.
• The drain allows flooding the kiln for a full, safe quench of the hot char and saves water compared to top/above cone water quenches. Hot quenching washes the char, reduces condensates (tar) and increases activity, pore volume and surface area of the biochar via steam activation.
• The quench water can be reused in subsequent burns. It just needs to be topped up from time to time with water and whatever else you want to add eg. liquid sea kelp, fertiliser etc.

The Kon-Tiki biochar kiln is the fastest, cleanest way to make medium-sized batches of biochar from local biomass with minimal processing, and condition it for application.

The Kon-Tiki deep-cone flame-curtain process was developed by Dr Paul Taylor (author of 'The Biochar Revolution' book) and Hans-Peter Schmidt at the Ithaka Institute in Switzerland in 2014. In 2020 its use has been recorded in 80+ countries. The kiln was named Kon-Tiki after the Peruvian sun God, and inspired by the voyage of discovery of the Kon-Tiki raft Thor Heyerdahl sailed across the pacific.

1. Low cost, simple and elegant compared to other biochar production technologies.
2. Proven, high quality biochar – fulfills all conditions for the European Union Premium Certificate for biochar.
3. The natural vortex dynamic of the Kon-Tiki cone kiln supports an “air-curtain” and flame cap that pyrolyzes the feedstock, burns the smoke and protects the char.
4. The Kon-Tiki has tested lower air emissions compared to other low cost kilns.
5. Rim shield provides safety, and heat protection, as well as clean combustion and uniform biochar.
6. Low feedstock processing requirements compared to other technologies.
7. Accepts a range of feedstocks, including mixed feedstocks and higher moisture content feedstock, in sizes from small off-cuts, through hog fuel and limb wood up to 1.2 metres in length and 10cm in diameter.
8. A high volume of biochar can be produced in a few hours. The volume yield is about 45% and mass yield about 17%, comparable to other kilns and gasifiers that produce a high temperature biochar.
9. Nutrient charging can be conveniently done during charring, quenching or post-production right in the kiln. Add,eg. sea minerals such as liquid kelp or SEA-90, molasses, blood and bone et al
10. Quenching liquid and nutrients can be easily captured and recycled or used for multiple purposes via a drain at the base of the cone.
11. Agronomic trials show the Kon-Tiki system to be especially effective for improving crop yield.
12. Relatively little training required to safely and effectively use the Kon-Tiki.
13. Clean up your property, and enjoy the fire while making valuable biochar.
14. The Kon-Tiki provides heat from biochar production, which can be developed for other purposes (e.g. cooking, water purification, drying, distillation of essential oils etc.)

• Small property holders, farmers, Foresters, sawmill operators and others with readily available feedstock, stranded biomass.
• Landowners and agencies concerned with toxic water and land pollution and remediation.
• Gardeners, farmers, and community gardens seeking greater yield and healthier more nutrient density crops.
• Entrepreneurs seeking early entry into the biochar revolution and market.
