    solar coffee roaster takes longer time to roast

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    My solar roaster suddenly takes longer to roast. It started in the change of the weather as its slowly leaving winter. 2 kg roast takes 27 minute to complete (usually 18 minute) It looks like its loses some heat but i checked the elements and they look ok plus the time to get to pre heat alarm set still takes 8 minutes. Its just when the beans are loaded it takes longer than normal for the temp to climb up. Does one one have any idea? Solar is almost a maintenance free roaster so i never do anything other than cleaning the exhaust pipes and emptying chaff collector.

    Does anyone know where i can take this roaster for a possible service?
    Thanks in advance

    You might have a major build up of ash around your elements which may be hampering heat application. The roaster might need a clean out, I use a compressed air gun to stir up ash etc and have the vacuum cleaner nozzle in the drum to extract the ash and dust from my Torrefattore.
    I have been doing this to stall having to remove drum and do a major clean out!

    Thanks for the feedback, I am based in Melbourne. Emailed coffee tech eng and Dan, the support guy promptly replied for me to check the heat elements. Found one is dead. So I am ordering 3 heat elements, might as well replace all of them. Thanks Greenman, I will clean the inside while replacing the elements. It would be posted EMS tomorrow. Hopefully I can get them by beginning of next week. Dan sent me a service manual as well, so very good service from coffee tech eng.

    I was about to say you might find its one of the 3 elements. With that said i have had some changes with mine too in recent weeks with the increase of some warmer weather. the service manual is very handy for replacing the elements and also the drum baring should it need replacing. Good luck with it all.

    I ordered the elements and they sent them with EMS the next morning. Price for the elements including shipping with EMS is $396 (After conversion from Euro) for 3 of them. There is youtube instruction on changing the elements. For those who own this roaster, this might come handy for you guys https://www.youtube.com/watch?v=P9UUWnN-gjA

    You can clean the bottom debris while doing elements replacement with vacuum cleaner.

    Chris, I didnt get the manual with heat elements replacement and drum bearing, would you care to share the updated manual with me please? Mine is manufactured in 2013. You might have the later one. Great to know some solar user here too.

    Great talking with you, i watched the video and after watching it i must say i could give you the manual but all of it is in the video. I noticed the only thing they didn't say which they mention in the manual and that is was when putting new element in you may need to place some heat suitable silicone around the base so not to allow the heat to escape. Its good to know about the vacuum out of the roaster too. Great video. I will email you the manual any how it might be good for reference.

    Cheers,

    Chris

    I would have thought that replacement elements would have been available from importer and site sponsor http://coffeesnobs.com.au/sponsors/2...australia.html

    Behmor Coffee Roaster
    Hi River,

    Having had a couple of roasters now one being an older 2kg Has Garanti and now this the 2kg Solar they are fairly different. I still have my HG roaster and still use both. If you were to go down this path I can only say from my own experience that the Solar roaster is a great roaster giving you the ability to roast very consistently with out having to think to much while roasting and giving you the ability to do other things (im not saying walk away and leave it roast unattended ). Where is the HG you need to be watching from start to end and you have much more control over the HG than the Solar I would say the Solar is better for someone who has less experience with roasting but if you wanted to alter the roasts on the solar its limited with the Solar as it is a Auto roaster which follows a built in profile. The only changes you make are the temp settings from when you drop the beans in and the temp setting for when you want the Element to turn off.
    All in all it roasts very consistently however the cons are that it requires a 15A plug and i have found you will use more power converted to cost than you would verse a gas roaster converted to cost. Which my HG one is gas. My Solar also has the Avinarki which is the After burner which has proven to be great.

    The one question mark I have about it is the cooling process. I don't like the fact the beans are still rather warm 5 mins after I would normally stop a roast in the Has Garanti and they are cool a min or so later. Keep in mind the Solar has a perforated drum and the Has garanti has a solid drum. More conduction on the Has garanti and more convection on the Solar.

    All in all its a great roaster. Mind you so is the Has Garanti.

    Cheers,


    Chris
