The practical guideline Hygienic compressed air in the food industry deals with the hygienic aspects of
- compressed air (from outside air to consumption point)
- including all conditioning, design, verification and monitoring
- including recommendations for energy consumption reduction
for application in the food industry.
Part of the guideline is a substantiation of the hazard and risk analysis.
2 Normative references (legislation and regulations)
There are three food safety laws that need to be considered in the EU:
- Hygiene regulation Reg. 852/2004
- Machinery Directive (2006/42 / EC)
- Materials regulations Vo1935 / 2004; Vo10 / 2011
And for (breathing) air (intensive contact with (pressurised) air)
- Directive on personal protective equipment
The FDA Code of Federal Regulations applies to the United States.
The standards for compressed air, driers, filters, appendages and hoses have been taken into account when drafting the guideline.
In addition, the other practice standards have also been considered: BRC v7, IFS v6, 3-A and more.
3 Terms and definitions
Own definitions, concepts from guideline EN 1672-2 and zone classification.
4 Compressed air installation - Principles
Overview of the components that make up a compressed air system, with attention to the different principles and variants that can be chosen for a component: compressor or blower, oil-lubricated or oil-free, kind of separators, after-coolers, dryers, and filtering and separation steps.
5 Risk analysis
It discusses what can be significant hazards to the food, which can come with compressed air. This yields a number of sources that are treated individually:
- (aspirated) ambient air
- suction filter
- air compressor
After the compression:
- wet air buffer
- storage and distribution
The risks are discussed per source, such as
- water vapour and condensate
- particulate matter
- micro organisms
- environmental dirt
- fragrances and flavours
- lubricating oil and grease
- dust formation by adsorbent.
Then recommendations are made for removing these hazards by source.
Where complete prevention of the hazard is not possible, the risks must be limited. It is indicated to which limits the compressed air must comply in terms of micro-organisms, moisture and the various contaminants.
6 Design requirements
In this chapter, the compressed air system is followed from intake to consumption point, and criteria and recommendations are given.
7 Verification & monitoring
Discussion of verifications of filters and of some quality characteristics of compressed air: residual moisture, residual oil, particles and microorganisms, and what measurement methods are available for this.
A brief overview where energy-saving measures are possible.
