Heat Gun Roasting Question
I have just purchased an Ozito 2000w heat gun to roast using a crank handle drum flour sifter set up but in the meantime tried roasting in a metal bowl with a wooden spoon to agitate the beans; problem is the beans never got hot enough to roast. I held the heat gun pretty close but it still didnít seem to work and I even held my hand in front of the hot air stream about 6 inches away and while it was hot it didnítí feel much hotter than a hair dryer .
Should the heat gun air stream feel a lot hotter, or does it just take a fair amount of time for the heat to build up? Just wondering if the heat gun I bought isnít up to the task.
Thanks in advance.
Heat guns usually have two fan speeds and they will often have variable heat level adjustment as well, check to see if it has the ability to vary the heat output. If you can put your hand in front it sounds like it is just idling along, 2000W should be more than adequate. I am not familiar with the sifter set up but a 2nd hand $5 - $10 bread maker from the Op Shop will have you well on your way to roasting great coffee
I used the same heat gun and used a metal kitchen colander and wooden spoon (I learnt a lot from this method) for 12 months until I bought a second hand bread machine. Never had a problem getting the beans to do their thing. The heat gun performed admirably and I still have it as a back up and for lighting the Weber Kettle BBQ etc - so that sort of indicates that the Ozito is definitely up to the task - if working properly. The bread machine has reduced the Popeye effect of my stirring arm though.
I think the heat gun will be more than sufficient, In a bowl i could only assume it would take a while as you are heating the beans whilst stirring. The issue i can see is the hot air will escape pretty quickly not allowing for any constant heat. Youd be better off roasting in a pan over the stove to start with or as Beanz above has said get a second hand break maker and look up on here how to rig it up. You would be wanting to keep a steady temperature and im only thinking what what you have said that this might not be happening with this method.

Good luck and keep at it!
Thanks for your replies everyone; I will definitely try again with your tips
For those interested this is the set up I am looking to build - https://www.youtube.com/watch?v=LivL...A&index=5&t=8s
I use the same heat gun, and it should be hot very quickly. I’ve had my worst burn ever from that gun btw, don’t touch the metal parts after use.
It takes a few minutes to notice any change in the beans though, so give them at least a few minutes.
If it's the same one I recently bought, it's definitely A LOT hotter than a hair dryer.
Check if the "temperature dial" on the side isn't wound all the way down to (-).
(this is the one I have https://www.bunnings.com.au/ozito-20...t-gun_p6290265)
Yep that's the one; I'll check the dial and try again and give it a bit of time to properly heat up. If that still doesn't work it might just be a faulty heat gun and I'll have to exchange it.

For those interested, I have built the roasting set up now and figured out the heat gun.
I have only done a small batch because I ran out of beans but it already looks more even than anything I was able to do in the popcorn maker.
