The very first batch has been made: apple banana coconut sorbet with chocolate oat cookie chunks and roasted soybeans. It took way too long to get a good consistency because of the bad insulation but tasted way too good to not continue with the project. Next step will be a waterproof case with proper insulation and a worm gear drive for the paddle. Then motorizing it with a window wiper motor, a PWM or BAM driver and a microcontroller which monitors everything. I plan to measure the current of the motor and establish a correlation of ice cream consistency and current consumption. With a small LUT (Look Up Table) the controller can then achieve a set consistency and hold it – from slush ice over sorbet up to heavy gelato.
A look into the cylinder of joy.
The final version of Icenberg will have a proper enclosure with an insulated top lid with a hole that will guide the axle.
Ice crystals form on the outside immediately after pulling the container out. Don’t lick it!
At some point the cordless drill and hand crank method failed because the viscosity was getting too heavy. The powerful lathe with VFD and transmission could help out with ease.
Cleaning up is quite easy with water and a cordless drill attached to the axle. Memo: Need to make a cap for the little window when mixing with 600rpm.
