I don't have any baffles yet but it is something I am wanting to get done as there are slight differences in the temps between the 2 ends of the drum.
With regards to emptying I just empty straight into a perforated tray underneath. Your…"
"Howdy Ben, Below is an image of the drum we had built locally. It is a perforated stainless drum on a nylon bush.
The image below shows the sample port and temperature probe that sits in the middle of the beans whilst roasting
It does display actual oven temp as well as the set temp but I wanted to have a reading of the temp in the beans so I also had a static probe put in the sample port. Not sure if that makes sense but I will try put up some pics so you can see…"
I have a rotisserie that I had an engineer convert into a drum roaster which seems to work really well. I also got him to put a sample port into the side of the unit to allow for sampling without having to open the door or stop the…"
I see you are from NZ and you are looking for cocoa beans. Try Whittakers brothers in Porirua. The source their cocoa beans from Ghana and actually I think they are the only larger size manufacturers in NZ to make their chocolate from cocoa beans. They are a larger company but if you can get through to them they most probably be able to help. Other wise try Brian from APS Chemicals in Auckland. They are Barry Callebaut reps for NZ and some while ago they could source cocoa nibs so maybe can help with cocoa beans as well.
I think you can still order 15kg of beans at a time from Tava even though they are not operational at the moment - they won't do anything else or any smaller quantities. Well at least they did for me about 4 months ago. Langdon and Samantha (Tava guys) use this site.
Yes you can get pure icing sugar here, CSR or Bundaburg do it in 500g bags for about $1 per bag. I use it for all of my choc making as it saves quite a bit of time.
I see you have discovered the tragedy that is the Australian/New Zealand chocolate situation. I don't know about NZ but in Australia if you look very carefully you can find Cluizel and Valrhona - if you want some top notch choc to compare with your own creations.
I got into choc making so I would have access to good chocolate.
Also if you are looking for beans in the Oz/NZ region try www.tava.com.au they sell Vanuatu beans that I mainly use. They are extremelly chocolatey, I use them to make a dark milk choc and it is my best bar - according to the family and friends circle.
