1、 Core working principle of equipment
The laboratory soft capsule machine achieves rubber molding and content filling through a precision controlled dual drum system. The gel solution (gelatin/plant glue) forms a uniform film layer under constant temperature conditions, and is pressed and formed by a rotating mold to simultaneously complete the quantitative filling of the drug solution or nutrient. Its core innovation lies in:
Micro scale mold processing technology: ensuring capsule seam accuracy ≤ 0.1mm and better sealing performance than traditional processes.
Intelligent temperature control system: The temperature fluctuation of the adhesive solution is controlled within ± 0.5 ℃ to avoid bubbles and uneven thickness.
Modular design: Quickly replace molds to adapt to different capacity requirements of 0.1-5ml.
2、 Key technological breakthroughs
1. Dust free filling technology
Using a peristaltic pump in a negative pressure environment for delivery reduces the risk of cross contamination by 90% (compliant with GMP Class C standards).
2. Online quality monitoring
Real time detection of capsule thickness and filling amount using integrated near-infrared sensors, with an automatic rejection rate of ≥ 99.7% for non-conforming products.
3. Low carbon and energy-saving design
The new electric heating system reduces energy consumption by 40% compared to traditional steam heating and is suitable for green laboratory certification.
3、 Typical application scenarios
New drug research and development: accelerate the formulation screening of sustained-release formulations and enteric coated capsules.
Development of nutritional supplements: achieve low-temperature encapsulation of thermosensitive substances such as essential oils and probiotics.
• Teaching demonstration: Visually demonstrate the interdisciplinary principles of colloid rheology and formulation technology.
