INDUSTRY COMPONENT

Perforated Drainage Surface

A perforated stainless steel surface designed for efficient whey drainage during cheese curd processing on industrial-scale tables.

Component Specifications

Definition
A precision-engineered component of industrial cheese curd drainage tables featuring uniform perforations that allow whey separation while supporting curd mass. This surface optimizes drainage efficiency through controlled hole patterns, slope design, and food-grade material construction to meet sanitary production requirements in dairy processing.
Working Principle
Operates through gravity-driven liquid separation where whey passes through perforations while cheese curds are retained on the surface. The perforation pattern, hole diameter, and surface slope create optimal drainage paths while maintaining structural integrity under load. Surface tension and capillary action are minimized through material selection and finish.
Materials
Food-grade 304 or 316L stainless steel, electropolished finish, Ra ≤ 0.8 μm surface roughness. Material thickness: 2-3 mm. Corrosion-resistant, non-reactive with dairy products, meets FDA/EC1935/2004 compliance.
Technical Parameters
  • slope 1.5-2.5°
  • open_area 25-35%
  • hole_diameter 3-5 mm
  • load_capacity ≥ 150 kg/m²
  • surface_finish Electropolished, Ra ≤ 0.8 μm
  • temperature_range -20°C to 150°C
  • perforation_pattern Staggered hexagonal
Standards
ISO 22000, ISO 14159, DIN 11850, 3-A Sanitary Standards

Frequently Asked Questions

What cleaning protocols are required for perforated drainage surfaces?

Requires CIP (Clean-in-Place) or manual cleaning with food-grade detergents. Regular inspection for clogged perforations and verification of drainage efficiency. Must follow HACCP protocols for dairy equipment sanitation.

How does perforation pattern affect drainage efficiency?

Staggered hexagonal patterns provide optimal open area (25-35%) while maintaining structural strength. This configuration prevents whey pooling and ensures uniform drainage across the entire surface area.

Can this component be customized for different cheese types?

Yes, perforation size, pattern, and slope can be adjusted based on curd characteristics. Soft cheeses may require smaller holes (3 mm) while harder cheeses can use larger openings (5 mm).

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
