demetri said:So is that $1.00 to $2.00 per lbs of coffee beans? Any idea of what the power consumption would be for a typical operation?
Say I roast 1,000 lbs of coffee beans a week, how much am I paying in roasting fees and how much power is the machine going to use typically to roast 1,000 lbs of coffee?
Around $1.38. We have a scale based on volume, but assume that's about the number. As far as power consumption it will be a whole heck of a lot less than your big roaster. We recycle the energy and actually use the roasting of the beans for energy just like any other hydrocarbon burn. We use catalysis to provide heat and energy which heats the incoming fresh air without the aid of electricity or device. THe beans act as fuel. THe drum heater actually shuts down to about what a hair dryer uses or less when you start roasting a lot in succession. We can actually run a 7200 watt heater at less than 10% for most of a roast and maintain in excess of 560 degrees if desired. Depends on the roasting profile assigned. In many cases we actually turn it off and use the recapture for almost all of the heating. I will say that the heat exchanger on this thing is HUGE. But who cares? The cat was custom designed by Englehardt, the leaders in the industry, especially for coffee. I can say that in five years we've never heard a single complaint about a rise in power usage and that being from people who never had a roaster before. Guess the bill didn't change much!
You're local Demetri aren't you? Why don't you come down and see it? Seeing is believing.
