    Electric versus gas roasters?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Has anyone got any information on the difference in quality control of roast between electric and gas for a 2 kg roaster?

    Hi There,

    Having had both a electric and gas roaster I can say from personal experiences they do roast a little different. There is a understand on this and to why they roast differently also. Don't quote me but a gas roasters going to have a solid drum so conductive heat is going to play much more of a part in the roasting process. Where as a perforated drum is on a lot of electric roasters. You are still going to get conductive heat however a lot of the heat transfer to the bean if going to be convective heat.

    Conduction and Convection, in my opinion two important components in roasting along with many many other aspects.

    It may be a personal opinion ans as i said having had two types of roasters one being gas and electric i found to have more control over the gas roaster for one. Flavors after roasting on the electric where a little more muted than those on a gas roaster. The repeat ability on the gas roaster i owned however was a lot easier to achieve mainly because the roaster had two set and forget temps for start and stop. Where is a gas roaster you will have the ability to adjust gas and on some 2kg roasters air flow. Once again coming back to conduction and convection.

    So i guess i ask when you say quality, both can produce great coffee, everything i have said above is knocked out by the person who is roasting ans the knowledge they have. Thats whats going to produce the quality.

    Just my two bob.

    Cheers,

    Chris

    I know nothing about gas roasters except that there is a lot of safety equipment and compliance required because of the risk of explosion.

    Gas combustion produces water and carbon dioxide so it is like the difference between a gas and an electric oven, the difference is quite considerable. Gas is also instant unlike electric elements. Gas is better for cooking in many ways.

    Well picked Javaphile! Does make you go ummm. Also asked about an espresso machine they are now selling that model two days later. If one was cynical would think the OP was trying to drum up enquiries for their own sales. Of course the positive way of looking at it could be after reading the words of wisdom above from two CS posters the OP decided to dump their $8k electric air bed roaster and buy a gas roaster.
