It makes biochar! All cones are made from 3mm HW350 weathering steel with a dished bottom for drainage. In other words, the kiln can be left outside to the elements 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 the crossbar on the cradle for emptying. Removable heavy duty solid rubber wheels on casters (2 with brakes) enable the 'Rolls' to freely move around and can be rolled onto and off a standard trailer for remote burns. For shipping/transportation, the 'Rolls' can roll onto a 1200x1200 pallet, or no pallet, for A to B. The 'Rolls' will be supplied with a galvanised 'Quad' (4 pieces) collapsible heat shield. A 1" ball valve on the drain can easily connect to 1" Ag line (commonly available in Australia) connected to an electric water pump, which is connected to an IBC for quenching the burn and draining the kiln after a burn (with the pump in reverse). The quench water can be reused in subsequent burns (just needs to be topped up from time to time with water and whatever else you want to add eg. liquid sea kelp).
The Kon-Tiki biochar kiln is the fastest, cleanest way to make substantial batches of biochar from local unprocessed biomass, 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.
Low cost, simple and elegant compared to other biochar production technologies.
Proven, high quality biochar – fulfills all conditions for the European Union Premium Certificate for biochar.
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.
The Kon-Tiki has tested lower air emissions compared to other low cost kilns.
Rim shield provides safety, and heat protection, as well as clean combustion and uniform biochar.
Low feedstock processing requirements compared to other technologies.
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 15cm in diameter.
A high volume of biochar can be produced in a few hours (up to 370 litres batch size). The volume yield is about 45% and mass yield about 17%, comparable to other kilns and gasifiers that produce a high temperature biochar.
A dished bottom (good for cone drainage if kiln is left outside) with 2" bottom drain. A 2" 316 stainless steel elbow welded to the bottom - this allows for many drain configurations. The drain allows flooding the kiln for a full, safe quench of the hot char. Hot quenching washes the char, reduces condensates (tar), and increases activity, pore volume and surface area.
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
The kiln comes complete with a sturdy tilting cradle that allows the biochar to be easily tipped.
liquid and nutrients can be easily captured and recycled or used for multiple purposes. Can be done with an IBC and electric water pump with portable battery, which can be charged from a
solar panel or mains charger.
Agronomic trials show the Kon-Tiki system to be especially effective for improving crop yield.
Relatively little training required to safely and effectively use the Kon-Tiki.
Clean up your property, and enjoy the fire while making valuable biochar.
The Kon-Tiki provides about 300kW of heat from biochar production, which can be developed for other purposes (e.g. cooking, water purification, drying, distillation of essential oils etc.)
The Kon-Tiki 'Rolls' costs AUD$3200. There may be up to a 2 month delay on production time following payment.
Shipping is additional cost. This is calculated before the order is confirmed.
Shipping to Australian customers only and no PO Boxes.
Tracking number and receipt will be provided.
Only Paypal payment accepted at this stage.
Product liability insurance is for manufacturing defects encountered in the first 15 days after delivery. This would include such things as brackets falling off and welds that break. The Kon-Tiki 'Rolls' is designed for outdoor usage, so, eg.the cone will develop a rusty patina which the HW350 weathering steel is meant to attain. There is no 6 month or 12 month warranty. After-sales support for life is available.
