Types of Liquid Filling Machines for Oral Liquid Production

Oral liquid filling machines are key equipment in the pharmaceutical and health supplement industries for precisely filling syrups, oral liquids, drops and other products. According to the degree of automation, working principle and application scenarios, liquid filling machines can be classified into the following types, with a focus on models related to oral liquid production:

1. Automatic Oral Liquid Filling Machine 

• Features: High precision and high efficiency, suitable for large-scale production. 

• Technology: Equipped with servo motors or peristaltic pumps for control, ensuring accurate filling volume (±0.5% error). 

• Applications: Filling of oral liquids, syrups, and nutritional supplements, compatible with glass bottles, plastic bottles, and ampoules. 

• Advantages: Integrated automatic cleaning (CIP/SIP), aseptic environment, and GMP-compliant design.

2. Rotary Filling Machine

Features: Continuous rotary operation with a production capacity of up to 200-500 bottles per minute. 

Application scenarios: Rapid filling of high-viscosity oral liquids (such as traditional Chinese medicine extracts). 

Key technologies: Multi-nozzle synchronous filling, combined with a visual inspection system to remove defective products.

 3. Peristaltic Pump Filler -

 Features: Contactless filling to prevent cross-contamination, suitable for oral liquid production with high hygiene standards.

Advantages: Easy to clean, capable of handling liquids containing particles or sensitive components (such as probiotic oral liquids).

 4. Piston Filling Machine

Applicability: High-precision filling (±0.2ml accuracy), commonly used for small-dose oral liquids (such as children's medications). 

Material compatibility: Corrosion-resistant materials (such as 316L stainless steel), suitable for acidic or alkaline pharmaceutical liquids.

Suggestions

For small and medium-sized enterprises: Choose semi-automatic or linear filling machines, which support flexible bottle type changes and reduce initial investment. 

For large pharmaceutical companies: A combination of fully automatic and rotary filling machines, equipped with visual inspection and MES systems, to achieve intelligent production. 

For special pharmaceutical liquids: Customized solutions (such as explosion-proof design, low-temperature filling). Contact us for one-on-one technical support!
