Roasting

Re: Roasting

I havent exactly put it to the test, but recal similar experiments using sand - it did vibrate and appear to move as one in the direction of the motor.

Re: Roasting

Well Im going to be a heretic....

Assuming the motor is rotating at reasonable RPMs the beans will mainly bounce about in all directions due to the vibrational energy imparted on the "bowl" from the rotating off centre weight - and this energy will be transferred from the bowl to the beans.

There will be too much momentum for them to rotate..... but there will be some overall rotation in the same direction as the motor shaft.... however this will be masked to a significant extent by the random motion of the beans....

Thats my guess : :

Really, the only way to prove this wrong or right is to build one and see what happens.

It could be the next big thing in home roasting Or not .......

Well the fan from the heat gun will have some influence once you get that far down the track.

Re: Roasting

Ive been doing some Google searching on vibrating shell cleaners and found:

"- A vibrating polisher is a bowl that sits on top of a vibrating block/motor. The parts dont roll around but vibrate up and down all the time."

The "parts" are in a medium of walnut shells (the abrasive)..... so Id imagine the same thing will happen with coffee beans....

But Im totally happy with the Corretto as it is .... so Ill be leaving it to someone else to prove this right or wrong.
