Spray Solutions Engineered for Hygiene

Why Hygienic Spray Design Matters

Hygienic production depends on equipment that cleans easily, performs predictably, and supports regulatory compliance. Lechler’s nozzle designs combine precision engineering with food grade materials to help processors achieve repeatable results.

• Designed for easy cleaning: Smooth, self draining contours and open internal structures reduce residue buildup and make every cleaning cycle more effective.
• Reliable, uniform coverage: Engineered spray patterns and precise droplet control ensure consistent wetting and cleaning across shifts, product types, and production runs.
• Efficient use of resources: Optimized spray impact and droplet size deliver powerful cleaning with less water and energy.
• Built for compliance: Food grade materials, traceable components, and available documentation simplify validation and audit preparation.

Sanitizer Spray Nozzles

Purpose: Achieve full, repeatable sanitation of process equipment including rinsing, alkali washes, and sanitizer phases, with minimal variation and maximum coverage.

Nozzle focus: Nozzle families specified by Lechler for disinfection/hygiene applications.

Recommended Nozzle Families

• Hollow cone spray nozzles: These are commonly used for area disinfection, spray cleaning of surfaces, and pathogen removal applications in food plant environments.
• Flat fan and full fan spray nozzles: Used for precise surface coverage in zones near conveyors, closures, and packing line areas that require sanitation sprays.
• Specialty hygiene nozzles (e.g., hygienic quick change, CIP ready): Designed for food and beverage specific production environments where line changeovers, sanitation frequency, and validation are critical. (While not always named explicitly as a family, Lechler’s hygiene focused offerings emphasize materials and installation suited for these tasks.)

Key Design Advantages

• Engineered spray patterns allow for controlled coverage of difficult to reach surfaces, helping avoid missed zones or shadowing.
• The ability to tailor droplet size and spray impact helps match the cleaning agent (rinse, alkali, sanitizer) to the surface conditions and soils.
• Compact, hygienic construction fits into production environments that have tight spaces and require frequent sanitation cycles.

Typical Applications

• Rinsing and sanitizing open conveyors, vats, or surface contact areas in beverage, dairy, or snack food lines.
• Targeted sanitizing of closure/neck surfaces, guide rails, filler turrets, or other hybrid production/clean zones.
• Hygiene sprays during product changeovers, end of shift sanitation, or CIP adjuncts in food & beverage facilities.

Technical Considerations for Specification

• Identify soils & media: Consider the residues (protein, fat, sugar, starch, minerals) to size spray impact, droplet size, and cleaning agent strength.
• Cycle mapping: Align nozzle choice to each sanitation step (rinse → alkaline → acid/oxidizer → sanitizer) rather than only production phases.
• Droplet design: Smaller droplets for wide coverage and wetting; larger droplets or higher impact jets where soils are thicker or more adherent.
• Flow & pressure validation: Ensure supply meets the nozzle’s required pressure & flow at the point of use, not just at the skid.
• Hygienic materials & seals: Ensure food contact approved stainless steels or polymers and elastomers compatible with disinfectants and CIP cycles.
• Installation & accessibility: Nozzles should be positioned and mounted so that they self drain, and permit routine inspection/change out

Common Questions

How do these specialized hygiene nozzles differ from basic spray nozzles?
Hygiene specific nozzles are designed with food contact materials, hygienic finishes (e.g., Ra ≤ 0.8 µm), self draining shape, and often quick service or tool free features. They also often come with documentation and support for validation and audits.

What if line speed, product type or soil changes?
By selecting from the hygiene design families (hollow cone, flat fan, etc.) with tunable droplet size or capacity, you can switch nozzle types or tips to match changes in viscosity, line speed, or soil load. Having spare tips and a documented changeover plan helps.

Can these nozzles be verified and documented for audits?
Yes. Each model can be specified by product number, capacity, material, operating conditions and is supported by Lechler’s documentation for food & beverage hygiene applications. Verification through coverage tests, photographic or fluorescent dye tests, and maintenance logs is possible.
