CCR-1kg Coffee Roaster

cosmic_couple22

OK have pulled the cooler tray apart and put it back together. Sorry up front if I have taken to many but Ididn't want to skip anything. [attachimg=1] cooling tray [attachimg=2] arm adjustment [attachimg=3] centre spindle I switched my upper manifold from right to left and all holes lined up. I do agree with Zane the design of the fan blades catch a heap of chaff, so much so I will investigate a different blade that isn't shaped like a drag line bucket. More photos to come for those thinking of reconstruction mods (BF) :thumb: Chester

Hope these are what you wanted BF [attachimg=1] t-arm [attachimg=2] lower sweep arm [attachimg=3] arms thats the external stuff ^-^

cosmic_couple22

lets go inside [attachimg=1] inspection cover [attachimg=2] inside to tray motor and across to fan [attachimg=3] housing [attachimg=4] sweeper motor everything seems well put together apart from the shape of those fan blades.

Fan assembly to go [attachimg=1] internal [attachimg=2] fan housing and manifold [attachimg=3] fan and motor [attachimg=4] manifold hope those help. Still a lot of chaff even in the blades of the lower fan and I have only roasted two 1 kg batches. Being a fireman myself I better keep a stiff clean out protocol. Nothing worse than your own crew coming to your house because it's burning down. :doh: Chester

I had a look this morning if you could point the rear manifold down. After taking it apart the answer would be not quite. The rear mount for the exhaust and manifold contacts the manifold outlet. You could rotate the manifold to about 45* down and redrill the holes in the heavier mounting plate. Intresting though, I switched mine from right to left to create a direct line to the chaff collector and after 2 roasts there is no chaff in the fan at all. Chester

I think i have seen it on ebay being sold for $4900 or so Just wondering how good that is :angel:

What a great roaster, thanks to BF for starting this thread and all the great information. I cannot add much at present except to say I have a bit of tidying up and organising to do in my garage in preparation for an arrival maybe late December. Dedicated power line with RCD, ventilation and a solid bench. Computer is OK,am planning on logging with an Arduino TC4C that i hope to order tomorrow. Cosmic - what a great setup, I like the ventilation, I hope to setup something similar and will be happy if it turns out even half as good.

Welcome Sholayer, its a pretty exciting time preparing for a new roaster and getting everything right. At under 5K you can't go wrong with this unit, it's robust and pretty well built. Easy to operate and tweak your roasts, it does take a little bit of practice getting a feel for how the temperature reacts to small adjustments, but thats part of the fun. :thumb: Same advice I was given, ventilate well, good lighting and start off with 10kg of a little bit forgiving bean and play with the roast profiles. Good luck Chester

Just finished re-wiring in an english board on the roaster, I now have a "Bake Switch" :rofl: Chester

I want to start getting some flexible or hard ducting for ventilation to/from the cyclone - can someone please give me outside diameter of the nozzles? I think the inlet and discharge are different diameters? Thanks, Chris

Had my first hic-up with the roaster today, the potentimeter that controls the heat failed. Discovered it when I went to pre heat the roaster and it wouldn't heat up. 😢 Wasn't something I had to touch when I wired in the english board so no real reason for it. Having trouble sourcing the right one in OZ so looks like Hong Kong and delivery after christmas if I can't track one down. AAAGGGGHHHHHH no roasting over christmas. An easy fix, just a frustrating wait. Chasing a 6mm Knurled Split Shaft Three Terminal Linear Taper Rotary Potentiometer B500K If any one knows a good supplier here please let me know. :thumb: Chester

Oh Chester, sorry to hear about thefailed pot, I will ask around. I realise timing is still an issue but John is bringing in a roaster for me very very soon and the factory may be able to supply one in the same shipment, possibly even spare heating elements if you dont have one.

First search on ebay - http://www.ebay.com/itm/6mm-Knurled-Split-Shaft-Three-Terminal-Linear-Taper-Rotary-Potentiometer-B500K-/390497036136?_trksid=p2047675.m1850&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D11%26meid%3D4032225841628548188%26pid%3D100011%26prg%3D1005%26rk%3D1%26sd%3D330810771368%26 KK

Thanks KK Yep did that, trying to source one localy before having to order over the internet and deal with christmas postage delays. Chester

Element14 formerly Farnell in Sydney?

cosmic_couple22

Thanks Sholayer :thumb: I will contact them in the morning and see if they have something close to what I need. I will drop John a line and arrange a spare just to be safe. Chester

as an interim measure, you can substitute another 500k pot. the split knurled knob doesn't matter from a functional point of view. shouldn't be too hard to track down the right item though. hopefully elrment14 will see you right. contacting john to get the correct/approved spare on its way is exactly what I would do.

cosmic_couple22

Just a quick follow up on the pot problem. Ordered a couple from a Sydney company on evil bay, not the cheapest but will arrive quickly ;D Sent John an email last night, first thing this morning I had an email and a phone call from John to confirm the problem and for him to arrange an original replacment part. These roasters aren't only a great product but also well supported by John. Thanks to all the quick replys of advice. Chester

Hi all, new to the forum and though I've been considering it as as concept for some time, new to the idea of roasting. Got talking to a friend who owns a cafe recently and after a few beers thought we might give rotating a try. Thought getting something the size of the CCR might be a good place to star. If his appreciation of flavor and my doggedness worked out, we might expand to a bigger machine at a later date. I've been looking at eBay for a while and can't see a link to the vendor of this unit. Any chance someone could post or PM a link? Alternately, anyone out these looking to get rid of a similar roaster... ;-) Will pay in the classified when I qualify to do so. Thanks!

I've been in touch with a manufacturer OS that makes a similar roaster, looks pretty much identical anyway: Alex Zhang from Zhengzhou Allance Trading Co., Ltd. I asked for a quote, delivered, for just 1x unit. His response: "As for 1Kg Electric Heated Coffee roaster, best FOB Price at USD1800. if you want delivery by DHL to Western Australia (Perth / Fremantle), DHL Charges at USD620. Total price at USD2420." Here's a link with a little more info: http://allance.en.alibaba.com/product/524854135-213144605/1Kg_Coffee_Roaster.html?edm_src=sys&edm_type=fdbk&edm_grp=0&edm_cta=read_msg&edm_time=realtime&edm_ver=e There are loads of manufacturers in China making these. Not sure if parts/manufacturing is shared, but alas, it seems you can get a Chinese 1kg elec or gas roaster for about $2500 landed. Of course, I should add a disclaimer about power requirements, quality of wiring, approval/standards, taxes, blah blah. I don't know. It could end up still costing $5k landed. Who knows? Who's got $2.5k to find out? 🙂
