Induction compatible vac chamber

[herbivore21]

Ok, so I know I've asked FC about vac chambers before. However, I have recently discovered the many benefits of induction in heat purging of concentrates.

So, I still want to go down the vac purge route. However, I really want to get my hands on a vac chamber that I can sit atop my induction cooker and apply low heat evenly during vac purge using said induction.

Thanks in advance!

Salutations Herbivore21,

...a vac chamber that I can sit atop my induction cooker and apply low heat evenly during vac purge using said induction.

Well, 1st of all i've got to wonder how low that heat needs to be (because it can get hot real fast) but in any case i must point out that my own IH plate happens to reject iron/nickel metal objects which don't conform to an expected range of cookware shapes - which roughly corresponds to the format of a DVD/CD-ROM 12 cm disc, minimally. If your target temperature were close to 250 °C (482 °F) then you may be lucky because there are thermostatic frypans now!...

Egzoset, I have found like many that the temperature of heat used in purge will in no small part determine the consistency of the final product.

IME shatter and crumble eventuate from lower maximum heat used in purging process. I have found 80c to be optimal in evaporating to reliably produce shatter, crumble is simply a matter of further drying out the shatter.

Actually, my induction cooker has no problem with diameters up to 26cm, would it be possible to find a small stainless steel vac chamber around this diameter? This is a slightly bigger diameter than a standard round pyrex pie dish.

Salutations Herbivore21,

Hummm... Somehow i doubt a constant 80 °C temperature can be provided on a stable/reliable basis but it sure sounds like yet another potential Curie-effect application (should the special alloy required for thermostatic action happen to be available)... So, how did you come to conclude the IH method was ideal for your goal anyway? Put aside the brief initial heat-up period i mean.

My IH plate doesn't even have a ceramic top this large while the coil under doesn't appear to support beyond 19 cm (dia.) or so i think, good luck finding affordable 26 cm IH cookware fit for your specific purpose!

I have somewhat mitigated the power cycling caused by the low temperature demanded in my relatively simple induction cooker unit.

I did this by pouring about 500ml of water into a 26cm induction frypan (a very decent one I found online for $50 AUD), then resting a pyrex pie dish in the water, it fits percetly. I then set the induction cooker to 80c. I am aware that when heating up, the cooker may momentarily exceed 80c, however, the water seems to provide a buffer to absorb that momentary excess heat without unduly effecting the product.

I am reliably making shatter and crumble every single time I use this setup. I have made shatter with reclaim. All with ISO as the solvent.

Hi again Herbivore21,

I have somewhat mitigated...

Since you must have explored many other alternatives already i can only hope a satisfying solution is found eventually. Well, with alcohol around i'd comment an IH plate makes sense as this is quite a suitable way to heat up water and safer too!
