Outline My vantage point as a syrupmaker Overall design requirements for mechanizing a mill Internet-based calculators to assist in meeting design requirements RPM and rpm calculator Torque and torque calculator Power and power calculator
Cow Barn Mule Shelter Corn Storage Vehicle Shed Pack Houses Bee YardMuscadines Tobacco Barns, Goat Shelter, Mulberries, Pecans, Chickens Smoke House, Ice House, Out House, Well Shelter (Wash Pots &c.) Small Fruits Feed Mill Blacksmith Shop Sugar Mill Yard Goldens’ No. 2 (New Model) Rollers: 6 inches long Juice output: 45 gallons per hour Power: 1 horse, heavy
The Journey from a “Trash” Mill... Goldens’ No. 2 (New Model) to a Finished Product. Kettle of Syrup
Design Requirements 1.Establish Target Revolutions per Minute 2. Establish Target Torque 3. Establish Target Power
Revolutions Per Minute Too Fast: Juice does not drip from bagasse before ejection from mill Base plate designs insufficient for large volumes of juice Wear on mill Safety concerns Too Slow: Decreased capacity Just Right: Surface Roller Speed: 27 feet per minute
Electric Motor, Right-Angle Speed Reducer, & Chain Drive Chain guard removed for illustration
Drive Train Design Use of Chain Drive: High mechanical efficiency (~95%) Inexpensive Low overhang load compared with belt drive Large sprocket on mill (6x): low overhang load and use of smaller speed reducer. Use of Right-angle Speed reducer: Low ratios have higher mechanical efficiency.
