Scharffen Berger Chocolate Case study
Process analysis
Assumptions
From the case we can see the following relations:
- 250kg of beans 185kg of nibs; This relation can be seen in the description of the act ivity Winnower, so we know that
1kg of beans 0,74kg of nibs
-
As stated in the description of the Conche activity: 1.400kg of semisweet chocolate contains 850kg of nibs, in other words, 1kg of semi sweet chocolate 850/1400=0,6071kg of nibs
1kg of nibs 0,46kg of chocolate paste; This one is explained in the
Melangeur activity (nibs are composed by 54% of cocoa butter and the rest used for the chocolate paste). Despite this, we assume that all the nibs are transferred to the next activity (Conche) in order to keep it coherent with the previous assumption (1400kg of the final product contains 850kg of nibs).
Only semi-sweet chocolate is produced by Scharffen Berger.
We assume that a month has 30 days and a year 365 days.
We assume that we are at the beginning of 2005 (1st of January)

Capacities
Activity 1: Cleaner
From the case we know that this activity has a capacity of 200kg of beans per 15 minutes. Although from these only 192kg remain (100kg beans 96kg clean beans), so we considered the capacity to be the output of the machine, the 192kg of beans per
15 minutes. It also says that in this activity there is only one machine, which works for
8 hours per day, 7 days a week. By the three simple rule:
192kg beans/15min
192*4=768kg beans/h
768*(185/250)=568,32kg nibs/h
568,32*(1400/850)=936,06kg semi-sweet choc/h
936,06*8=7488,45kg semi-sweet choc/day
7488,45*30=224653,55kg semi-sweet choc/month
Activity 2: Roaster
Here we separated the roasting part from the cooling part. It also says that in this activity (roasting and cooling) there is only one machine, which works for 8 hours per day, 7 days a week. This one has a capacity of 250kg beans
