Sterilizing & Depyrogenation Tunnel Machine

Sterilizing & Depyrogenation Tunnel Machine

At our facility, we specialize in manufacturing advanced dry heat sterilizer machines adjusted for pharmaceutical vials, syringes, and ampules. Our equipment uses hot air to achieve thorough sterilization and reduction of chemicals, important for product safety and compliance with industry regulations. Designed with functionality focus, our dry heat sterilization equipment features a stainless-steel mesh belt that smoothly conveys vials through preheat, hot, and cool zones, where they are exposed to HEPA filtered air. This process prepares them properly for next filling operations, maintaining the highest standards of cleanliness and purity.

As industry leaders in dry heat sterilization technology, we offer a range of models to accommodate vials ranging from 2ml to 100ml, with varying outputs and changeover capabilities to suit different production demands. Whether you're searching for a quality dry heat sterilizer for your need or require a custom dry heat sterilizer machine, our products are made to meet your specific needs. With competitive dry heat sterilizer prices and whole support, we are dedicated to delivering solutions that improve performance and quality across pharmaceutical manufacturing processes.

The sterilizing and depyrogenation tunnel uses high-temperature dry heat to sterilize and remove pyrogens from glassware containers and other equipment used in pharmaceutical manufacturing. Initially, the equipment is loaded onto a conveyor belt and passes through a pre-heating zone. This assures the temperature of the equipment is uniform before it enters the main heating zone. The heating zone features a series of heating elements arranged to provide consistent temperature distribution throughout the tunnel.

During the heating process, the equipment is exposed to temperatures typically ranging from 250°C to 400°C for 15 to 45 minutes. This heat treatment effectively destroys any bacteria or microorganisms present on the equipment and removes any pyrogens. After the heating process, the equipment passes through a cooling zone to lower its temperature to a safe level before being unloaded from the conveyor belt. Once cooled, the equipment is ready for use in the production of sterile pharmaceutical products.
