Objective
deterime CFM requirements of Garlic Peeler Currently using a rented outdoor compressor. Problems
- Lines freeze
- Uses Diesel. Expensive to operate.
- expensive to rent
- requires maintainence
Query
What capacity is required to run the peeler?
Method
The system has 400 US gal storage tank. which has a capacity of 53.5 cubic feet At 120 psi (8.2 bar) the tank contains 438 cubic feet of compressed air. at 90 psi (6.2 bar) the tank contains 331.7 cubic feet of air.
Determine the output of indoor compressor
The indoor compressor takes 3.8 min to fill the tank from 90 psi to 120 psi. therefore the capacity of the compressor is:
- capacity at 120 psi - capacity at 90 psi divided by the time to fill = cfm output of compressor
- (438-331.7)/3.8min = 28.0 CFM MEASURE OUTPUT OF COMPRESSOR FROM 90 TO 120 PSI
deterime the CFM consumed by Peeler
filled the tank to max pressure 120 psi (8.2 bar) and closed the feed to the tank so that no more air would be added. This gives us a measured amount of air to use. We then ran the peeler at various pressures and recorded the time and the pressure to drop. From this data we can calculate the CFM consumed at the various pressures.
| Regulator Set | Start psi | end psi | cubic Feet | time | CFM |
|---|---|---|---|---|---|
| 115 psi | 120 psi | 93 psi | 96 cu.ft. | 0.5 min | 192 CFM |
| 100 psi | 120 psi | 94 psi | 92 cu.ft. | 0.5 min | 184 CFM |
| 90 psi | 120 psi | 98 psi | 77.6 cu.ft. | 0.5 min | 155 CFM |
| 90 psi | 120 psi | 87.5 psi | 116 cu.ft. | 0.75 min | 154 CFM |
| 80 psi | 120 psi | 82 psi | 136 cu.ft. | 1.0 min | 136 CFM |
