Model UH- 1 Coaxial Rotary Biochar Kiln.

Oxygen-free Pyrolytic Heating is entrained and captured exclusively between the flights of an auger moving the biomass along an induction heated rotating inside cylindrical surface. A heat gradient in the center of the cylinder wall is generated without flame or combustion gases by means of an induction coil that is positioned around the coaxial center of a rotating cylindrical steel drum.

Liquid vinegar effluent stored and mixed with cooling water at 100:1 ratio and sold as product.

Variable pyrolysis temperatures, precise control thereof.

No hydrocarbon fuels needed, all electric power to 10 kVa.

Variable speed differentials between the auger and drum for residence time and Biochar BB size.

In-Line Biomass Chopper at Infeed Hopper ensures uniform particle sizes

Water bath biochar immersion cooling provides excellent single step heat transfer.

Tar vapors (Soot) egress and accretion in Condenser Plenum on removable accretion plates.

Variable BB particle size is achievable via internal transport surface geometry and feed speeds.

This arrangement establishes a compound surface rolling plane geometry that generates spheroidal biochar BB’s during pyrolysis as they tumble between the moving flights and the hot opposite rolling compound curved cylindrical surface.

The entire main auger is actually a gas manifold that is suspended at both ends with custom rollers bearings therein, whereas the outer drum rotates in the opposite direction and has more convention bearing abutments.

The induction coil (center) is stationary at all times and can dissipate approximately 5 kW of electrical energy sufficient to generate the required pyrolytic heat.

Induction heating of the cylinder walls controls the pyrolysis temperature ( 950 deg C ) to within 20 degrees Celsius of any selected temperature for any biomass in process and the residence time at temperature is controlled with our unique and novel Auger Plenum Transport System. The inside surface geometry between the flights and drum wall will generate spheroidal nodules from the size of a BB to a marble.

Major Features and Attributes;

The raw hemp chips are chopped to a uniform and consistent size first before entering the chip storage hopper.

Then they are conveyed into the kiln by means of auger flights and converted into biochar at high temperature between them.

The hot biochar BB’s are expelled into a flowing water bath contained by an oval tank wherein a partially submerged belt conveyor scoops out the wet biochar BB’s as they approach.

Now they are air dried as they move to the holding silo or gaylord storage bin.
