Gains:
- Explains why maintenance access is critical in the site plan
- Recognizes common layout errors
- Can evaluate the plan from the operator's perspective
When drawing the layout plan, it is assumed that the fit of the machines is sufficient. However, the facility will be operated for thousands of hours a year and will receive regular maintenance. A location that fits but cannot be maintained means equipment that is neglected in a short time.
Common mistakes
- Inability to fully open the roller cover: the roller cannot be dismantled for shaving.
- Not leaving space to remove plansifter sieve drawers.
- Not considering a lifting point for engine replacement.
- Dead corners with no cleaning access: food safety risk.
- Placing electrical panels in dusty areas.
- Sampling points are at inaccessible heights.
Control by operator's eye
Read the plan from the perspective of the operator who will work in that facility, not the engineer who drew it: "Where will I change the sieve cloth, where will I get the sample, how will I lower this engine?" Every question that has no answer is a design deficiency.
Show the floor plan to the commissioning team. A person who knows the field can find the problem that is not visible on paper in ten minutes.
