4 oranges * 700 people = 2800
add some buffer oranges
Try to do all the squeezing within an hour, as buffer on time.
3000 oranges / 60 minutes = 50 oranges per minute to process
Using a standing orange press - chop orange in half. Put halve into press, push press down, open it up, pop orange out. repeat.
So perhaps 1 orange every 5 seconds. (Batch cut a bunch up initially). Approx 12 oranges a minute, lets say 10 oranges a minute for an employee.
So 5 employees can press 50 oranges a minute.
Add an extra employee as buffer.
So 3000 oranges, 1 hour, and 6 employees.
Instead buy a dozen automatic juicers and charge the client to buy new ones.
[1]The juice in an orange is highly variable by season, producer, ect. Just add it to the bill.
