MSD 1 System Level Design Review
Biomass Compressor
TEAM 13432
Terminology
 Biomass – any grown organic matter to be used in the system
 Compressor – increases pressure on the biomass
 FVP – force versus power
 TIE – team industrial engineering
 TC – team compression
 TSP – team slicing and packaging
Goals
• Present design criteria and customer needs for
approval by customer
• Update customer in regards to concept generation
• Settle upon final systems architecture for approval
by customer

System Architecture
Feasibility Analysis
Feasibility Analysis
What the mechanical testing will answer
1. What does the force v. displacement curve look like?
2. Does moisture have an effect on the results?
3. Is the compressed material isotropic or an-isotropic?
4. What are the effects of the three different materials?
5. What is Poisson’s ratio for the materials tested?
6. What are the effects of the orientation of the material on resulting forces?
7. What is the force needed to eject the brick from the compression chamber?
8. Do the results scale?
9. What are the effects of dwell time in compression chamber?
10. What is the maximum achievable density of brick?
11. How does friction affect the compression and ejection of the biomass?

OVERVIEW
2 lbs bricks
Goal is to promotes Water Intake for
Proper Hydration
Convenient, Lightweight and Easy to
Use
Quickly Expands in a Bucket of Water
to About One Flake of Moist Hay
Compressed Blend of Premium Grass
and Alfalfa Hay
NUTRIOTIONAL INFO:
Crude Protein (min) ................ 8.00%
Crude Fat (min)........................ 1.50%
Crude Fiber (max) .................... 37.00%
Ash (max) ................................ 9.00%

Schaetzel family hay brick production
• Purchasing a hydraulic machine ($350,000)
• Plant plans on using 20 tons of hay per day
• Economically unfeasible to transport hay more than 100 miles away
