Reliable protection with the EHEDG zone concept

Food and beverage production – select the right filter for the respective hygiene zone

In food and beverage production, even minimal contaminant levels in the air can lead to contamination of the entire food production. The result: Reduced shelf life or even worse consequences. Producers utilize a zone concept in order to protect foods and beverages during every production process.

The zone concept classifies the individual production areas by their hygiene risk and specifies the hygiene level that must be achieved in each production step. The required purity level varies depending on the product being made and the stage of production.

Multi-stage filter systems from Freudenberg reliably filter particles and microorganisms from the air and have proven themselves ideal for compliance with the strict hygiene requirements.

Understanding the zones

Depending on the hygiene requirements, the various zones of a production facility are categorized as high (high-risk), medium (high-care) or basic (low risk).

Satisfying the highest hygiene demands

100% audit compliant for food

In the food industry, a hygienic production environment is essential for smooth processes as well as compliance with statutory requirements. With controlled and monitored air quality (temperature, humidity and particle concentration), product contamination can be reliably minimized. In addition, the clean ambient air contributes to the protection and comfort of the employees. Take no chances: with filtration solutions for the food and beverage industry that meet the most stringent requirements. Additional guidelines and standards also exist to ensure that the stringent hygiene requirements for the production processes of the food and beverage industry are met.

Clean rooms capable of achieving an extremely low particle concentration in the air are increasingly common in practice. For determining the purity level of a room, there are two established classification systems to choose from: EN ISO 14644-1 and the "Good Manufacturing Practice” guidelines (GMP).

There are also a number of important rules and standards in place to ensure that the stringent hygiene requirements on the production processes of the food and beverage industry are met.

Better protection for consumers

HACCP concept

Contaminated food is a danger to human health and, in the worst case, can even lead to a pandemic, such as the swine flu. The Hazard Analysis and Critical Control Points concept (HACCP) was developed to prevent this sort of dangers. This concept is used for risk analysis of critical control points in the production process and thereby contributes to increased food safety and consumer protection.

EHEDG

The “European Hygienic Engineering & Design Group” (EHEDG) is a consortium of equipment manufacturers, food industries, experts in the food industry as well as research institutes and health authorities that offers assistance and guidance with regard to hygienically safe food production. The topic of air filtration is specifically addressed in the EHEDG Doc. 47 guideline whose recommendations regarding filtration performance, process safety and hygiene are met by Viledon Filter products.

Viledon air filters satisfy the requirements

VDI 6022

VDI Guidelines 6022 “hygiene requirements for ventilation and air-conditioning systems and units” defines clear specifications for the use in sensitive application areas, such as clean rooms. Viledon pocket and HEPA filters satisfy all VDI 6022 criteria without restrictions. The materials used offer no basis for bacterial or fungal growth and are moisture-resistant at up to 100% relative humidity. Prescribed hygiene monitoring and inspections are conducted by our filter experts on site directly with the customer.

Classification of clean rooms

EN ISO 14644-1

For the production rooms, the purity levels of the air vary depending on foodstuff as stipulated in EN ISO 14644-1. This guideline classifies rooms according to their particle count per cubic meter (m³). For example, a clean room for food production must observe the limits for ISO Class 8. As confirmed by the Fraunhofer Institute, the use of Viledon HEPA filters with a plastic frame is recommended up to ISO Class 2.

Our dedication to greater food safety

BRCGS - Global Standard for Food Safety

BRCGS' Standards (formerly known as BRC Global Standard for Food) define clear requirements for food safety in the food industry, for food processing operations and companies that package open foods. The standardization of the quality, safety and operating criteria helps producers ensure faultless and safe product quality for consumers along the entire food chain. As a member of the BRCGS Partner Connection Programme, we are committed to maximum protection throughout the complete production process.
