I note in passing that these requirements are not dissimilar to a small electric clothes dryer. Might be a source for parts/ ideas.Hemipatuca said:Summary: DIY coffee roaster
Reference https://www.physicsforums.com/threads/force-needed-to-rotate-a-drum.915197/
Hello, My name is Héctor and I love coffee, I'm working on a diy drum coffee roaster. Drum + load= 50 pounds, rotation needed = 10-60 Rpm, length from 20 to 30 cm. How can I determine the motor power that can turn my drum? Can someone help me please?
Thank you in advance
A DIY Drum Coffee Roaster is a homemade machine used to roast coffee beans. It typically consists of a rotating drum, a heat source, and a motor to rotate the drum. It allows coffee enthusiasts to roast their own coffee beans at home.
The coffee beans are placed inside the rotating drum, which is heated by a heat source such as a gas burner or electric coil. The drum rotates to ensure even roasting of the beans. As the beans heat up, they release moisture and oils, resulting in the characteristic aroma and flavor of roasted coffee.
The recommended motor power for a DIY Drum Coffee Roaster depends on the size and weight of the drum. Generally, a motor with a power of 30-50 watts is sufficient for a small to medium-sized drum. However, for larger drums, a motor with a power of 100 watts or more may be needed.
It is important to choose a motor that is suitable for the size and weight of your drum. A motor with too little power may not be able to rotate the drum effectively, while a motor with too much power may cause the beans to roast too quickly and unevenly. It is best to consult with a DIY coffee roasting community or expert for recommendations on the appropriate motor for your specific setup.
Yes, it is important to take safety precautions when using a DIY Drum Coffee Roaster. Make sure to use heat-resistant materials for the drum and to keep a safe distance from the heat source. It is also recommended to wear protective gear such as gloves and goggles when handling hot beans or operating the roaster. Additionally, always monitor the roasting process closely to prevent any accidents or fires.
