Induction hot plate for cold smoking?

Yes Phil, that's the design.

I've just measured the mesh on mine - wire about 150 µm, close to three holes / mm. I reckon that's near enough 80 mesh. Wouldn't go much finer as it would clog and be too flexible, and one might get away with something a little coarser.

There's plenty on Ebay, item 130959838753 looks about right. A fiver for an A4 sized sheet including postage. Search using "stainless mesh 80". I cut it with a cheapo pair of kitchen scissors, don't use the best as they get knackered quickly.

Caustic soda in a plastic tub cleans the csg brilliantly,available from supermarkets, make it up with hot water to get it going really well, rule as per school days add the acid to the water, also fantastic for all oven wear/racks, DO NOT USE ON ALUMINIUM.

Regards Gary.

PS Most induction hobs have a over heat sensor, if the heat is not being drawn out of the cooking vessel quickly enough which could be the case heating sawdust, the unit will switch off, also the pan will heat very evenly so basically all the sawdust will be heated at the same time.

FYI here's a link to significant discussion of a pumped-air method CSG, including plans.

Maybe I simply haven't used mine enough for it to clog up but no problems yet.

Excellent advice all of you, thanks.

The CSG has cleaned up nicely, but I will use caustic soda next time. If I can get dust at the right price from Ashwood's, then I will stick with the CSG.

A good source of stainless mesh here http://www.meshdirect.co.uk/Stainless-S ... -mesh.html cheaper than Ebay, but larger sheets.

Reference the clogging of the "blown" generators. At first, I thought the problem was my oak chippings, but even after oven drying, it still clogged, I had to keep raking the chippings to get them to fall down the tube to burn. I've built two of them, one with the air blowing through a tube across the bottom, and one with the tube at the top. I think the main problem was our damp British air, as the air tube from the aquarium pump choked up with water as well. They may well work really well on a nice hot sunny day here, but that is going to severely limit the amount of times they can be used. :)

Has anyone tried something like a 10mm copper pipe with 3mm holes in it placed in the centre of the csg tracks so that the core of the dust also gets some air for combustion, another bonus could be that the heat conducted along the copper could pre warm/dry the dust before the main burn came along, it could also help with different grades of dust as you are not soley reliant on the outermesh grills for supplying air?

I will get round to trying myself but time and health is against me at the moment but just thought i would mention the idea.

I've only twice had problems with the dust, and that was solved by drying it in a low oven. That said, I bought my dust well before the reported change to the Ashwood dust spec.

I'm wondering whether, if the dust is now coarser, a slightly larger holed mesh, or a couple of mm gap between the channels, would solve the problem.

Just got off the phone to Ashwoods, they advise using the Raucher Gold E150-750, kiln dried dust. This dust is 0.2 to 2.5mm., so 80 mesh should be ideal, having an aperture of 0.1854mm.

Price for a 15kg sack is £10.00 plus anther £10.00 for carriage, making it £1.34 per kg. Better than £9.30 for 600g.!!!!

Thanks Gary.

Jollyjohn, did they confirm that it works in the CSG?

Yes Phil, I specifically asked the question. Do you think differently?

Before I order any, I will make absolutely sure it will work.

By the way, I have had a good look at my CSG, and I'd say it is a coarser mesh than 80, more like 40.

No, it's no problem, it's just that when I rang them shortly after people had the problems with the CSG, they seemed a little evasive - I guess it's understandable in the circumstances. They were really pleasant when I first visited to get 'chips' for hot smoking and even gave me a half a sack of cherry: about £20 quid's worth.
