• US Roaster Corp
• Owned and operated by Dan Joliff
• Located in Oklahoma City, Oklahoma
• Manufactures coffee roasters
• 3 kilo sample roaster - 150 kilo industrial roaster
• Refurbishes old coffee roasters

Roasting Innovations’ mission was to develop a 300 kilogram roaster that would be safe and reliable with the ability to be easily reproduced. The team accomplished this by redesigning the drum and drive train components of the roaster. Materials used to build the roaster were chosen to maintain optimal quality of the product being roasted.

Roasting Innovation needed to design and produce a drum and drive train for a 300 kilogram roaster that could withstand temperatures up to approximately 600oF so as to reduce destruction of the quality of the roaster due to thermal expansion. The 300 kilogram roaster needed to be able to roast exceptional coffee to the user’s taste, be easily reproducible, remain safe to operate, and environmentally friendly.

ΔL = the change in length due to thermal expansion (in) c = coefficient of thermal expansion (oF) Li = initial length of the drum (in) Tf = the final temperature (oF) Ti = the initial temperature (oF)

Thermal Expansion of 300 Kilogram Roaster: 0.6 inches

• Large scale coffee companies
• Folgers
• Maxwell House
• Southern California
• Air Pollution Standards

• Probat
• Entire drum rotates
• Exit door is a small hole in front
• Mixes comparable to other machines

• Diedrich Manufacturing
• Full drum rotates
• Mixes comparable to other machines
• Small front bean removal

• Quick bean exit
• Even Roasting
• Minimizing power consumption
• Cost
• Improved mixing
• Customer Survey
• Thermal expansion
• Minimize Friction

• Completed competitive and industrial analysis
• Developed three alternatives to be chosen from by
• ur client based on cost and design preferences
• Chose a design and began calculating specific

requirements and details

Assumptions

• No Friction
• All beans are lifted from bottom to top

P = WhN

P = power (hp) W = weight (lb) h = max. height beans need to be lifted (ft ) N = Speed of shaft rotation (rpm)

• System pressure at 100 psi
• 2 Humphrey Cylinders
• 2.5 in bore
• Force = 630 lbs.
• Versa Valve
• 3 position

• 2 Norgren Mufflers

Rotati ting g Shaft

• Smaller rotating mass
• Less HP loss due to

rubbing

• Less load on bearings
• Allows for basic belly dump

design

• No dead zones
• Allows for thermal

expansion

• Curved fins increases

bean movement

• Large surface area of

fins

• Fin placement for

elimination of dead zones

• Consistent color scheme to provide a uniform look
• Used previous logo and website as a base
• This allowed previous customers to recognize new

marketing materials

• Trade show must-haves
• Business card
• Brochure
• Consumer must-haves
• User and safety manual
• Specifications sheet

• Appeal to a larger market including large coffee houses and

roasting factories

• Highly energy efficient
• Cost efficient
• American made
• Improved mixing of the coffee beans
• Quick bean evacuation

• Pictorial user and safety manual
• Walk-through for first time users
• Belly dump
• Quick bean evacuation
• More even roast
• Shaft rotation
• Cuts down on horsepower requirements

• Projected income after 5 years = $1,500,000
• Cost to manufacture and promote = $10,000
• Price of the finished product = $300,000
• From communications with U.S. Roaster we are assuming

that they can market, sell, and produce up to 5 per year.

• Our calculations only include the drum and drive

mechanism.
