TFZRJ Aseptic Vacuum Emulsifying Batching System (Explosion-proof Type) is engineered to handle high-risk formulations—products that are both biologically sensitive (requiring sterility) and chemically volatile (containing high concentrations of alcohol or solvents).
This equipment is essential for manufacturing products like alcohol-based toners, serums with volatile actives, or transdermal pharmaceutical gels where safety and purity are non-negotiable.
Here is the detailed technical breakdown of this specialized system.
🛡️ Core Concept: Dual-Protection Design
This system combines two distinct engineering disciplines:
- Aseptic Design (Hygiene): Ensures the product is free from bacteria and contamination (pharmaceutical grade).
- Explosion-Proof Design (Safety): Ensures the machine does not ignite flammable vapors generated during the process (chemical safety grade).
⚙️ Key Technical Features
Since the system handles flammable materials (like ethanol), every electrical component is shielded to prevent sparks.
- Explosion-Proof Motors: The homogenizer and stirring motors are sealed and cooled to prevent surface overheating.
- Ex-d / Ex-de Junction Boxes: All electrical connections are housed in heavy-duty casings that can contain an internal explosion without letting it escape.
- Intrinsic Safety Barriers: Sensors (temperature, level, pressure) use low-energy circuits that cannot generate enough heat to ignite gas.
- Static Control: The entire machine is grounded to prevent static electricity buildup, which is a common ignition source.
- Material: All product contact parts are SUS316L (medical grade stainless steel) with a mirror polish finish (Ra ≤ 0.4μm). This prevents bacteria from hiding in microscopic surface imperfections.
- CIP/SIP Systems:
- CIP (Clean-in-Place): Automated spray balls clean the tank interior without opening it.
- SIP (Sterilize-in-Place): The system can be sterilized using saturated steam (121°C - 145°C) to kill all microorganisms before production begins.
- Sanitary Valves: Uses diaphragm valves instead of ball valves to eliminate "dead legs" where fluid could stagnate and breed bacteria.
- Homogenizer: High-speed rotor-stator system for mixing. In an explosion-proof setup, the mechanical seal is critical to prevent volatile vapors from escaping the pot and reaching the motor.
- Vacuum De-aeration: Removes air bubbles. In an explosion-proof context, the vacuum pump exhaust is often routed through a condenser or solvent recovery system to capture evaporated alcohol, preventing it from entering the factory air.

🎯 Ideal Applications
This specific "Aseptic Explosion-Proof" combination is required for:
- Alcohol-Based Toners & Astringents: High ethanol content requires explosion protection; skin application requires aseptic hygiene.
- Perfumes & Fragrances: Highly flammable alcohol bases.
- Transdermal Gels: Often use volatile solvents to help drugs penetrate the skin.
- Nail Polish & Removers: Solvent-heavy formulations.
- High-Active Serums: Products with volatile vitamins or unstable actives that need a sterile, oxygen-free (vacuum) environment.
Summary: The Aseptic Vacuum Emulsifying Batching System (Explosion-proof)provides maximum safety against fire/explosion while guaranteeing maximum purity for sensitive biological products. It is more expensive than standard machines due to the specialized motors, sensors, and cabinet purging systems required.
