Pharmaceutical Powder Sterilization and Drying Tunnel Furnace
Category：Tunnel Oven Production Line
Introduction
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.
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.

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.
