It doesn't take much primary air, so it is best if the base of the TLUD is air-tight, and the primary air is controlled by adjusting the size of a very small aperture.  The size of that aperture may be about 1 - 5% of the cross sectional area of the TLUD reactor.

Julian I am a big fan of TLUD stoves for their cleanliness and yes I
am sure they would work for this gari roasting, I think I would aim
for several TLUD tubes run in batch sequence, swapping out finished
ones while others maintain a flame.

 Overall for a continuous process using woodchips  I think a
conventional downdraught or crossdraught gasifier may be better, I
realise that would not leave as much char but is that an issue in this
scenario?
