Medical Industry Tunnel Furnace

The Medical Industry Tunnel Furnace is a high-precision continuous thermal processing equipment specially designed for the pharmaceutical, medical device, and biotechnology industries. It uses far-infrared heating, hot air circulation, or microwave heating technology to allow materials to pass through the heating tunnel at a constant speed driven by the conveyor system, achieving continuous, efficient, and uniform drying, sterilization, depyrogenation, or curing processes.The entire equipment is constructed with GMP-compliant SUS304 or SUS316L stainless steel, featuring a strict Class 100 cleanroom control system to meet the high cleanliness requirements of medical production environments.

Applications

Glass Container Sterilization

Used for drying, high-temperature sterilization, and depyrogenation after cleaning of vials, ampoules, infusion bottles, and other pharmaceutical glass containers.

Medical Device Curing

Used for adhesive curing and coating drying of medical components such as catheters, indwelling needles, syringes, and plastic or rubber parts.

Medical Packaging Material Drying

Used for drying and sterilization of cleaned medical packaging materials, bottle caps, aluminum caps, and other related components.

Bioproduct Thermal Processing

Used for constant-temperature drying of pharmaceutical raw materials, biological reagents, and powder formulations.

FAQ

Q1: What is the maximum working temperature of this tunnel furnace? Can it meet depyrogenation requirements?

A: The maximum working temperature is usually 350℃–400℃. It can fully meet medical industry depyrogenation processes that require maintaining temperatures of 300℃–350℃ for a certain period of time to remove pyrogens.

Q2: How does the tunnel furnace maintain Class 100 cleanliness?

A: The equipment is equipped with a high-temperature resistant HEPA laminar flow filtration system. Through vertical or horizontal laminar airflow circulation, the air inside the tunnel is continuously filtered to ensure the core heating area reaches Class 100 cleanliness.

Q3: Does the equipment support medical data recording and audit requirements?

A: Yes. The control system includes an audit trail function that automatically records temperature curves, alarm logs, and operator modification records. The data is protected against unauthorized changes and complies with GMP and FDA-related requirements.

Q4: Can the conveyor speed and temperature be adjusted for different products?

A: Yes. The equipment adopts variable frequency speed control and independent multi-zone intelligent temperature control. Different process recipes for vials, infusion tubes, and other products can be set, stored, and recalled through the touchscreen interface.

Q5: Does the equipment include a cooling section? Can products be packaged immediately after exiting?

A: Yes. The tunnel furnace can be equipped with a cooling section. The rear section usually adopts high-efficiency filtered cooling fans to reduce product temperature to near room temperature (such as below 40℃). After cooling, products can directly enter the next packaging or filling process.
