Filling of Hard gelatin capsules part 1, auger fill principle, vibratory fill principle #pharmaguide

Summary

In this video, the channel 'Pharma Guide' discusses the process of filling hard gelatin capsules, focusing on two primary methods: the auger fill principle and the vibratory fill principle. The video covers the components and mechanisms of the semi-automatic capsule filling machine, including the auger drive, agitator blade, and hopper. The auger fill principle involves rotating an auger to ensure consistent dosing, while the vibratory fill principle is used by machines like those from Osaka. The video also demonstrates the capsule filling steps: rectification, separation, dosing, rejoining, and ejection. Viewers are encouraged to subscribe and share.

Takeaways

• 📹 The video introduces heart gelatin capsule filling techniques and focuses on two principles: auger fill and vibratory fill.
• 🔄 Four main principles for capsule filling are highlighted: auger fill, vibratory fill, piston tamp (Rosetta and dosing disk devices), and vacuum fill.
• 🛠 The auger fill principle uses a semi-automatic capsule filling machine with four key components: auger, agitator blade, hopper, and filling ring.
• 🔧 The auger, which looks like a screw, rotates via a motor drive to ensure continuous dosing flow into capsule bodies.
• 💡 The agitator blade helps mix the filling material within the hopper for even distribution into capsules.
• ⚙️ The filling process involves placing empty capsules in the filling ring, which rotates on a turntable under the hopper.
• ⚖️ The fill rate of capsules depends on the auger's speed, with faster rates producing lighter fill weights due to shorter dwell times under the hopper.
• 📏 Capsule filling via the auger fill principle is volumetric, meaning the amount of powder depends on capsule volume and auger speed.
• 📦 Vibratory fill principle uses vibration to feed powder into capsules, with Osaka machines commonly employing this technique.
• 👍 The video concludes with a step-by-step demonstration of capsule rectification, dosing, and reassembly, encouraging viewers to subscribe and share.

Q & A

What is the main topic of the video?

The video focuses on the filling of hard gelatin capsules, specifically explaining two principles: the auger fill principle and the vibratory fill principle.

What are the four principles of capsule filling mentioned in the video?

The four principles of capsule filling mentioned are: auger fill principle, vibratory fill principle, piston tamp principle (with Rosetta device and dosing disk device), and vacuum filling principle.

What is the auger fill principle?

The auger fill principle involves using a semi-automatic capsule filling machine where an auger (screw-like structure) rotates to drive the powder into empty capsule bodies through the hopper.

What are the four primary components of the filling head in the auger fill principle?

The four primary components of the filling head are the auger drive, agitation drive, hopper, and the auger itself.

How does the auger drive function?

The auger drive rotates the auger at a constant speed to produce a continuous dosing flow of powder into the capsule bodies.

What is the role of the agitation drive?

The agitation drive rotates counter to the auger at a slow speed, helping to mix and guide the powder down to the capsule bodies.

How does the filling process work in the auger fill principle?

The empty capsules are placed in a filling ring on a turntable under the hopper. The auger rotates to drive the powder into the capsules, and the fill amount is controlled volumetrically.

What affects the fill weight of capsules in the auger fill principle?

The fill weight is influenced by the rotation speed of the auger. A faster rate results in a lighter fill weight because the capsule bodies spend less time under the hopper.

What is the vibratory fill principle?

In the vibratory fill principle, primarily used by Osaka machines, powder is filled into capsules through vibrations, ensuring an even distribution of the powder.

What are the steps involved in capsule filling using the auger fill principle?

The steps are: 1. Rectification of capsules (placing empty capsules in the filling ring), 2. Separation of caps from bodies, 3. Dosing of the fill material, 4. Rejoining caps and bodies, 5. Ejection of the filled capsules.
