2.3. Commissioning and connecting to the installations
The commissioning of the SR25 coffee roasting line usually takes place at
the customer’s premises, after
COFFED technicians install and assemble the line. The coffee for the commissioning needs to be supplied
by the final user, unless stated otherwise in the purchase agreement. The commissioning test
encompasses a mechanic test (that checks all the mechanical parts and their controls) and a technological
test. The technological test covers roasting one batch of green coffee under production conditions.
2.3.1. Electrical installation
The SR25 coffee roasting line is equipped with a five-wire main power cable (three phases, neutral and
ground). The voltage is 400V, 50Hz,
If the local regulations require electric measurements to be made, they need to be performed by authorized
personnel with the necessary qualifications.
2.3.2.
Gas installation
In order for the SR25 coffee roasting line to work properly, LPG or natural gas source needs to be
connected.
The gas train diameter is ½ inch.
2.3.3. Exhaust installation
The final user is obliged to connect the SR25 coffee roasting line to an exhaust installation according to the
guidelines provided by the
line’s manufacturer. An additional COx detector needs to be installed if the local
regulations require that. The chimney diameter is 15cm.
2.3.4. Pneumatic installation
Compressed air needs to be connected to operate the SR25 coffee roasting line. The pneumatic installation
should deliver at least 7.5 bar of constant, stable pressure. Quick fit connectors are used to connect the air,
