Hygienic Design: Self-Draining Surfaces and Sealed Parts

The Importance of Hygienic-Oriented Design

Hygienic-oriented design is critical in food processing, pharmaceutical manufacturing, and biotechnology, where strict sanitation standards must be met. NHK Group’s approach focuses on:

• Self-Draining Surfaces: Components are engineered with inclined angles to prevent liquid accumulation, ensuring that all water and cleaning solutions drain completely.
• Sealed Movable Parts: Moving parts are sealed to prevent bacterial ingress and contamination, reducing maintenance downtime and cleaning complexity.
• No Exposed Threads: Exposed threads can harbor bacteria and food particles, making them difficult to clean. NHK Group eliminates these in favor of enclosed or flush-mounted designs.

By integrating these design principles, NHK Group helps industries achieve superior hygiene levels while reducing operational costs associated with cleaning and maintenance.

Industries Benefiting from NHK’s Hygienic Solutions

NHK Group’s hygienic machinery components are widely used in several industries where strict hygiene and sanitation standards are required:

• Food and Beverage Processing: From dairy and meat processing to beverage bottling, NHK’s components ensure compliance with global hygiene standards, minimizing the risk of cross-contamination.
• Pharmaceutical Manufacturing: NHK’s designs support sterile environments by preventing microbial growth and ensuring that cleaning protocols can be executed effectively.
• Biotechnology & Life Sciences: Laboratories and production facilities rely on NHK’s self-draining and sealed parts to maintain the integrity of biological substances.
• Cosmetics and Personal Care: NHK’s components help prevent contamination in sensitive cosmetic formulations, ensuring high product quality and safety.

Material Selection for Optimal Hygiene

To meet the highest hygiene and durability requirements, NHK Group uses:

• Stainless Steel (AISI 304 and AISI 316): Both grades are corrosion-resistant, durable, and easy to clean. AISI 316, in particular, offers superior resistance to chemicals and saline environments.
• Food-Grade Polymers: Certain applications require the use of FDA-approved, non-porous plastics that resist bacterial growth.
• Hygienic Sealing Materials: NHK integrates high-performance elastomers such as EPDM and silicone to ensure a secure seal that prevents microbial penetration.

Real-World Case Studies

Dairy Processing Efficiency

A dairy production company struggled with cleaning inefficiencies due to stagnant water accumulation in their processing lines. By switching to NHK’s self-draining and sealed components, they reduced cleaning times by 25%, leading to significant water savings and reduced detergent usage.

Improved Hygiene in Beverage Bottling

A soft drink manufacturer faced contamination issues due to exposed threads in conveyor system components. After replacing these parts with NHK’s hygienic alternatives, contamination incidents dropped by 30%, and cleaning cycles were optimized, reducing water usage by 20%.

Pharmaceutical Cleanroom Compliance

A pharmaceutical company required sterile, easy-to-clean machine leveling feet. NHK’s sealed, self-draining stainless steel feet ensured full compliance with FDA and EHEDG standards while reducing cleaning downtime by 15%.

Enhanced Food Packaging Sanitation

A ready-to-eat meal packaging facility implemented NHK’s sealed castors and fasteners to streamline their cleaning process. As a result, microbial counts decreased significantly, leading to a 40% reduction in product rejections due to contamination.
