If you think about the different processes that are involved in making drugs, you’d find that capsule filling is one of the most important. Whether you’re working with tablets or capsules, your ability to seal these structures and keep them sealed will significantly go a long way in ensuring their quality across the board.
That said, when implementing proper capsule filling, there are several machines that you can make use of. This article will look at the different types available, as well as how best to approach them as a manufacturer.
Types of Encapsulation Machines
Without further ado, let’s take a look at the different types of encapsulation machines that are available to drug manufacturers. Generally, you have the following options available to you:
Hard Gelatin Capsule Machines
First on the list, we have the hugely popular hard gelatin capsule machines. Some call them encapsulation machines as well, but they function as a piece of equipment that helps to cover drugs and other substances with hard gelatin capsules.
Generally, hard gelatin capsules come in different sizes and capacities, which allows them to easily fit into different scales of pharmaceutical and nutraceutical production. To work this machine, you will need to prepare your material, then form the capsule shell itself. Fill the material, seal your capsule, and insect it to make sure that everything is set. Then put it in the right packaging.
At the end of the day, the benefit of these machines is that they help to automate the entire encapsulation process. This way, you’re sure of efficiency, accuracy, and consistency across the board.
Soft Gelatin Capsule Machines
Also known as softgel encapsulation machines, softgel capsule machines are specialized tools that primarily help in making soft gelatin capsules. These capsules come with gelatin shells, which are surrounded by a liquid or a semi-liquid material that’s filled inside. As you know, the fill material is what holds the active pharmaceutical ingredients and other substances.
A soft gelatin capsule machine allows you to prepare your fill material, form your gelatin ribbon, then complete your dosing process. From there, you can form your capsule, cover it, and let things dry out normally.
Remember the palace of inspection, then complete the packaging and round out the process entirely.
The benefit of these machines is pretty simple – they can easily achieve precision, and they make uniformity easier. So, if you have sensitive formulations that you need to hold, these machines are perfect for you.
Semi-Automatic Capsule Fillers
The semi-automatic capsule fillers are machines that are built to help fill capsules with the materials that are dispensed when they are digested. Unlike the fully automatic options, these ones still have a concept of manual labor needed to operate. And while they can be a tad stressful, they also provide an avenue for you to ensure proper accuracy.
Plus, these machines offer a cost benefit to their fully automated counterparts. So, if your budget it on your mind, you should be able to enjoy considerable savings with the semi-automatic capsule filler.
As you can imagine, the benefit of semi-automatic capsule fillers is the fact that they provide that seamless balance between automation and manual labor. This way, they provide an avenue for greater efficiency and consistency, while also allowing you to be as flexible as possible in your operations.
Automatic Capsule Filling Machines
As you can imagine, the fully automated capsule fillers don’t have any form of manual work in them. In both the pharmaceutical and nutraceutical industries, these machines provide speed and efficiency in production, while also ensuring that you can fill your capsules as accurately as possible. So, you really don’t have much to worry about.
With their build, these machines make for optimal efficiency and reliability. And in large-scale operations where you need speed and effectiveness, these machines easily slot in.
Generally, fully automatic capsule fillers come with some of the following features:
Working At High Speed: A primary function of these fillers is to work in high-speed production settings. They can fill thousands of capsules every hour, making them perfect for large-scale manufacturing.
Everything Is Automated: The machines handle everything you need them to do. Unlike the semi-automatic fillers, you really don’t need to do anything here – just let them work uniformly and consistently.
Accuracy In Dosing Control: Automatic capsule fillers also offer a considerable amount of accuracy in dosing control. Essentially, they make it possible for you to fill your capsules with the desired quantity of the material you need to fill.
Versatility In Sizing: Automatic capsule fillers are also very flexible. And as such, they can handle different capsule sizes. You won’t need to do much changeover as you move between the capsules, so you should be fine.
Capsule Orientation and Alignment: In most cases, these machines come with mechanisms where you can automatically orient and align the empty capsules just before they are filled. This ensures that alignment is done well, and the risk of jamming can be reduced as much as possible.
The Work Of Power Handling: An automatic capsule filler can feature an advanced power handling system. It could be vacuum suction, dosing discs, or anything else, which allows it to properly dispense the granular or powdered materials into the capsules. Generally, these systems help to cut down on dust generation and ensure precision in dosing as much as possible.
Built-In Quality Control: We should also mention the fact that some automatic capsule fillers can come with quality control steps. These could be capsule integrity checks, weight monitoring, and even rejection mechanisms that push out the defective capsules.
Maintenance Isn’t So Difficult: Thanks to their impressive build, these fillers are actually built to be easily cleaned and maintained. You have features like toolless disassembly and smooth surfaces that make wiping as seamless as could possibly be.
Capsule Banding Machines
The capsule branding machines generally help in the pharmaceutical space, applying a band or ring around capsules as soon as they are filled. Interestingly, the band actually serves different purposes – including the actual sealing and providing any additional branding should you need that for your meds.
In general, capsule branding machines work in this manner:
You load the capsules that have been filled onto the machine. Remember that the capsules are usually filled and sealed with the same automatic fillers we pointed out earlier.
The machine will immediately apply brands or rings around the capsules, with the brands being made with materials such as cellulose and gelatin.
Immediately, the bands are applied with heat sealing. Thanks to heated sealing elements – or rollers – the band material is properly melted and sealed securely around the capsules.
Capsule Counting and Filling Machines
Finally, we have the capsule counting and filling machines. As you can imagine, every pharmaceutical operation needs to have a proper eye on numbers. You want to make sure that your meds are appropriately numbered, and that they are properly filled. These machines automate all of these processes, ensuring that you don’t have to worry about accuracy on that front.
As for how they work, you begin with capsule loading and counting, then push your capsule to the filling station. Remember to verify the accuracy of your process, then you can close and seal it if you want. From there, take the capsules to a labeling station where you have labels with the right product information.inspect what you have, clean and maintain the machine, and you’re good to go!
In general, the work of these machines will be to streamline the process of filling the capsules into the right containers. They optimize accuracy and efficiency, so your process works like clockwork.
Considerations for Choosing the Right Encapsulation Machine
If you’re running a pharmaceutical operation, one of the most important things you need to consider is how to get the perfect encapsulation machine. And given the fact that you have so many options to choose from, being able to make the right choice is incredibly important.
To that end, you might want to consider the following factors when deciding in the long run:
What Do You Need?
First, you need to understand the requirements of your production plant. Are there particular operations you need to prioritize? Can you perform some of them manually or would you need to do things more automatically? From there, you can decide the machine to work with.
Take A Look At The Technicals
You also need to think about whether the technical specs of the machine are compatible with your plant and its needs. This way, you know you’re getting what you need and you’re not being short-changed.
Think About The Money
Generally, the financials shouldn’t stop you from pursuing efficiency. Nevertheless, you need to make sure that you have a good handle on the money front. Will you be able to afford the machinery you’re trying to get? If you can, then go ahead.
At the same time, you need to also look into things like maintenance and other long-term expenses that you might incur down the line. This way, you’re safeguarding your financial interests not just today but in the long run.
How Do You Upgrade Your Stack?
Another important thing you need to consider is the possibility of making upgrades and scaling up your technology stack. Essentially, you want to ensure that as you scale up, your machinery can do so with you.
At the end of the day, you don’t want to end up with machines that won’t be able to scale up with you. So, you have to be very careful here.
