How is hygienic fluid processing different from non-hygienic applications?

Hygienic fluid processing and non-hygienic fluid processing differ significantly in terms of equipment design, operational standards, cleanliness requirements, and the industries they serve. Here are the key differences between hygienic and non-hygienic fluid processing applications:

Equipment Design and Materials:

Hygienic Fluid Processing: Equipment used in hygienic fluid processing, such as pumps, valves, tanks, and pipelines, are designed with smooth, crevice-free surfaces, sanitary seals, and hygienic materials like stainless steel or food-grade plastics. These designs minimise the risk of bacterial growth, facilitate easy cleaning and sterilisation, and prevent contamination of the processed fluids.

Non-Hygienic Fluid Processing: In non-hygienic applications, equipment may not have the same level of surface finish, sealing, or material requirements. While still durable and functional, non-hygienic equipment may not be suitable for applications where cleanliness and product integrity are critical.

Cleanliness and Sterilisation:

Hygienic Fluid Processing: Hygienic processing requires stringent cleanliness and sterilisation protocols to ensure product safety and compliance with regulatory standards. Equipment and pipelines are regularly cleaned, sanitised, and sterilised using approved methods and chemicals to prevent microbial contamination and ensure product quality.

Non-Hygienic Fluid Processing: While cleanliness is still important in non-hygienic processing, the level of cleaning and sterilisation may not be as rigorous or standardised. Non-hygienic applications may focus more on functionality and process efficiency rather than strict hygiene requirements.

Industry Standards and Regulations:

Hygienic Fluid Processing: Industries such as food and beverage, pharmaceuticals, biotechnology, cosmetics, and healthcare adhere to strict hygienic standards and regulations (e.g., FDA, EHEDG, 3-A Sanitary Standards). Equipment used in hygienic processing must meet these standards to ensure product safety, quality, and compliance.

Non-Hygienic Fluid Processing: Non-hygienic applications may not be subject to the same level of industry-specific standards and regulations related to cleanliness and hygiene. However, they still need to meet general safety, environmental, and operational standards.

Risk of Contamination:

Hygienic Fluid Processing: The primary concern in hygienic processing is to minimise the risk of microbial contamination, cross-contamination, and product spoilage. Equipment design, cleaning protocols, and operational practices focus on maintaining a hygienic environment throughout the fluid processing chain.

Non-Hygienic Fluid Processing: While contamination risks still exist in non-hygienic applications, they may not be as critical or closely monitored compared to hygienic processing. Non-hygienic processes may deal with a broader range of fluids, including non-food-grade materials or non-sterile substances.

In summary, the main differences between hygienic and non-hygienic fluid processing lie in equipment design, cleanliness standards, industry regulations, and the level of risk management regarding microbial contamination. Hygienic processing prioritises product safety, quality, and regulatory compliance, while non-hygienic processing may focus more on operational efficiency and functionality.
