Mesh Belt: Temperature Range Ambient to 350°C, Width 200-1200mm

Component Specifications

Definition

A precision-engineered continuous conveyor belt constructed from interlinked stainless steel wires, specifically designed for high-temperature depyrogenation processes. It transports glass vials, ampoules, or syringes through controlled heating zones to eliminate pyrogens and achieve sterility while maintaining product integrity.

Working Principle

Operates as a moving platform that carries pharmaceutical containers through sequential heating zones. The mesh design allows uniform heat penetration from both above and below, while mechanical drive systems (sprockets or drums) provide controlled linear motion. Thermal expansion compensation mechanisms maintain belt tension and tracking stability at operating temperatures up to 350°C.

Materials

AISI 316L stainless steel (most common), AISI 304 for less corrosive environments, or specialty alloys like Inconel for extreme temperatures. Wire diameters typically 1.0-3.0mm with mesh openings 2.5-12.7mm depending on container size.

Frequently Asked Questions

Why is stainless steel used for depyrogenation tunnel mesh belts?

Stainless steel (typically 316L) provides corrosion resistance, high-temperature stability, cleanability, and compliance with pharmaceutical GMP requirements for product contact surfaces.

How often should mesh belts be replaced in depyrogenation tunnels?

Typically every 2-5 years depending on operating cycles, but regular inspections for wear, corrosion, or deformation should determine replacement timing. Preventive maintenance includes tracking adjustment and tension checks.
