WHAT WE HAVE TRIED
Thermocouples were borrowed from campus and affixed to the pizza oven
The temperature on the oven was set to 600 F and planned to decrease form there
Based on thermocouple and oven thermometer readings, the oven never reached over 300F
Cheesecakes were run through and the depanning was timed – the cheesecake temperatures were tested
Because of the missing coils, the temperature could not increase above 300F and was often less than that
The cheesecakes did not show any decrease in depanning time as they could not get any warmer than normal
PIZZA OVEN MANIPULATION
WHAT WE HAVE TRIED
Stainless Steel Inserts created using RIT machine shop
Inserts meshed well with cheesecake crumb and spinner head
Grease formed under insert instead of laying on top
Crust stuck to inserts and therefore could not be easily removed
INSERT TEST
WHAT WE HAVE TRIED Tested idea using
buckets filled with warm water, placing pans in water at times increasing by 10 seconds
Difficult to get quantitative data about depanning times during initial testing
Testing occurred separately from regular line; cheesecakes were not being depanned at that time
Operators were helpful in giving their thoughts/opinions during initial testing
Best times & temperatures seemed to be 30-40 seconds and 100F based on number of bangs and operators reactions
If this is pursued, the water bath would be an option to replace the pizza oven
WATER BATH
WHAT WE KNOW
Pizza Oven
Heat transfer experiments aren’t an
option due to pizza oven restrictions
Inserts
Stainless steel is unlikely to work as an
insert due to low thermal conductivity
SS has a lower coefficient of friction - grease might slide to outsides when crumb
is spun
WHAT WE KNOW
Water Bath
Operators gave positive feedback about
cheesecake quality and level of ease of the
depanning
Scheduling
Running low on ‘no cost’ options, may need to consider greater cost-
intensive ideas
One week behind where we wanted to be starting
MSDII, pushed presentation back one week to test inserts &
water bath
OPTION A: WATER BATH
1. Run larger scale experiment
2. Gather data that
can be used for
comparison to current
process
3. Examine possible
ergonomic effects
4. Make changes
and improvements to the
design
5. Develop an
implementation plan to be used
by Wegmans
6. Train employees
on new process
OPTION A: WATER BATH
The early results were promising
Would replace pizza oven
Won’t be very cost-intensive to implement
AdvantagesVariables are tougher to control
Hard to compare to current process
Disadvantages How to scale it up to meet production needs?
Challenges
OPTION B: COST INTENSIVEIdeas to Test:• Bakeable Insert - Cake Rings• Handled Cake Remover System • Table Conveyor • Key Lime Pie Tin System
OPTION B: COST INTENSIVE
1. Brainstorm
a list of possible solutions
2. Use Pugh evaluation
to determine
which ideas are
viable
3. Design, order
materials and build
4. Run experiment
s to test the builds
5. Make changes
and improvements to the
design
6. Develop an
implementation plan to be used
by Wegmans
OPTION B: COST INTENSIVE
Higher potential to improve ergonomics
All new ideas that haven’t be tested or implemented previously
Advantages Limited time to complete full process in MSD 2
Will require some up front investment
Disadvantages What is the budget for ROI for any cost intensive ideas?
What designs will be manageable for integration?
Challenges
OPTION C: METAL INSERTS
1. Identify the root causes of the problems that occurred during testing
2. Find solutions to
those problems
3. Test to make sure problems have been eliminated
4. Run large metal insert experiment
5. Develop a plan to
integrate inserts to current process
OPTION C: METAL INSERTS
The early results were promising
The team has a some idea of what caused problems
Won’t be very cost-intensive to implement
AdvantagesMore time consuming route to take
Uncertainties exist
DisadvantagesWhat material should be tested as an alternative?
What were the actual root causes of the problems that occurred?
Challenges
GOING FORWARD
Current Date: Week
6 (March 3rd)
Project Handoff
Date: Week 14 (May 7th)
The team has 9
Weeks remaining
- Decide what direction(s) to go in- Set a defined end goal for end of MSDII- Develop a schedule to follow to guide us toward achieving our end goal
Short-term Plan:
