Pharmaceutical Powder Sterilization and Drying Tunnel Furnace

The pharmaceutical powder sterilization and drying tunnel furnace is a continuous drying and sterilization equipment specially designed for the pharmaceutical, biotechnology, and fine chemical industries.The equipment utilizes far-infrared heating, microwave heating, or hot air circulation heating technology, allowing powder materials to move forward on the conveyor belt while uniformly receiving high-temperature hot air or electromagnetic wave radiation.It can destroy the DNA structure of microorganisms within a very short time to achieve complete sterilization, while rapidly evaporating moisture inside the powder materials, realizing continuous and automated dual processes of drying and sterilization.

Product Applications

Drying of Powdered Active Pharmaceutical Ingredients:

Used for the final dehydration and drying of various traditional Chinese medicine and Western medicine raw material powders.

Sterilization of Traditional Chinese Medicine Powder:

Used for sterilizing traditional Chinese medicine powders and herbal extract powders, reducing the total bacterial count (eliminating microorganisms such as mold and Escherichia coli).

Processing of Antibiotic Powder Injections:

Used for aseptic drying and sterilization treatment of pharmaceutical excipients and powders before sterile filling.

Inactivation of Biological Products:

Used for thermal inactivation and dehydration of certain biologically extracted powder materials with relatively good thermal stability.

Product Parameters

Product Features

Efficient Continuous Operation:

The assembly line operation mode eliminates differences between production batches.

Uniform Sterilization:

Three-dimensional penetrating heating ensures consistent heating both inside and outside the materials.

GMP Compliance:

The fully enclosed structure is equipped with cleaning-in-place (CIP) and sterile laminar flow protection systems.

Intelligent Temperature Control:

Multiple heating zones with independent temperature control achieve ±1℃ accuracy and prevent local overheating.

Energy Saving and Environmental Protection:

Hot air circulation recovery technology provides high thermal efficiency and prevents powder leakage and dust contamination.

FAQ

Q1: Can this equipment meet the data traceability requirements of GMP certification?

A1: Yes. The system adopts a medical-grade PLC control system with three-level authority management. It can record, print, and export process curves such as temperature and conveyor speed in real time.

Q2: Can this tunnel furnace be used for extremely heat-sensitive pharmaceutical powders?

A2: Yes. We recommend a microwave vacuum tunnel furnace or a low-temperature laminar flow tunnel furnace for such applications. These systems can achieve rapid drying and sterilization under low-temperature conditions below 60℃, ensuring that the activity of pharmaceutical materials is not damaged.

Q3: How can the problem of powder flying and material loss caused by airflow inside the tunnel furnace be solved?

A3: The equipment adopts low-speed air circulation technology and specially designed microporous Teflon or stainless steel conveyor belts. Meanwhile, a high-efficiency powder recovery device is installed at the exhaust outlet to minimize powder loss.

Q4: Is the cleaning and disinfection of the tunnel convenient? Will dirt accumulate inside the equipment?

A4: The interior of the equipment adopts a fully welded mirror-polished design without dead corners. It is equipped with an automatic lifting mechanism or CIP cleaning spray nozzles, allowing thorough cleaning of the tunnel interior and VHP (vaporized hydrogen peroxide) disinfection.

Q5: How should the heating method be selected (infrared heating vs. microwave heating vs. hot air circulation)?

A5:

Hot air circulation heating is suitable for conventional porous materials.

Infrared heating is suitable for surface drying and shallow sterilization.

Microwave heating is suitable for thicker powders requiring rapid simultaneous internal and external drying and sterilization.

We will select the appropriate heating method according to the characteristics of the pharmaceutical materials.
