How the LYYGZ5-25 Oral Liquid Production Line Protects Sensitive Components?

1. Gentle Cleaning Process

• Ultrasonic Cleaning Technology: Utilizes a vertical ultrasonic bottle washer (LYQCL series) to remove internal bottle contaminants through high-frequency vibration (instead of mechanical friction), thereby avoiding structural damage to sensitive active ingredients.
• Segmented Rinsing Procedure: After ultrasonic cleaning, the process proceeds with sequential water and gas rinses (e.g., nitrogen or sterile air) to ensure complete removal of residual cleaning agents and minimize the risk of chemical contamination.

2. Accurate Temperature-Controlled Sterilization and Rapid Cooling

• Tunnel-Type Hot Air Circulating Oven (LYASMR series): Features a gradient heating mode, enabling precise control of sterilization temperature within the tolerance range of sensitive substances (for example, ≤80℃ for certain biologics), thus preventing thermal degradation.
• Rapid Cooling Module: Immediately activates post-sterilization to minimize high-temperature exposure time, helping preserve the activity of thermolabile components such as peptides and probiotics.

3. Enclosed Filling and Inert Gas Protection

• Fully Enclosed Filling Environment: The filling and capping machine (LYGZ series) operates under Class 100 cleanliness, isolating the process from external microbial and particulate contamination.
• Nitrogen Laminar Flow Coverage: Creates an inert gas barrier (e.g., nitrogen) within the filling zone to prevent oxidative reactions and loss of activity in oxygen-sensitive substances (such as vitamin C and antioxidants).

4. Intelligent Process Control

• Mechatronic Design: The intelligent electronic control system continuously monitors temperature, pressure, and filling accuracy (error ≤±1%), ensuring parameter stability and eliminating the impact of mechanical fluctuations on product stability.
• Automatic Fault Diagnosis: The system identifies abnormal conditions (e.g., over-temperature or filling deviations) and triggers immediate shutdown to protect sensitive product batches.

5. Optimized Material Compatibility

• Contact Surface Materials: Key components in direct contact with the product, such as conveying tracks and filling needles, are made from 316L stainless steel or medical-grade polymers to prevent metal ion migration or adverse chemical reactions.

Application Examples:

• Probiotic Oral Solutions: Low-temperature sterilization (≤60℃) and rapid cooling preserve strains’ viability.
• Traditional Chinese Medicine Extracts: Inert gas protection prevents oxidation of flavonoids.
• Peptide Nutritional Liquids: Closed filling environment prevents protease contamination and degradation.

This design achieves precise process control along the entire production chain, balancing manufacturing efficiency with the integrity of sensitive ingredients.
