When it comes to selecting a filling machine that suits your needs, it is essential to understand the differences between the available technologies. The two most popular systems are volumetric filling machines and peristaltic filling machines.
In this article, we will compare these two technologies to help you make the best choice for your production.
1. How Volumetric Filling Machines Work
Volumetric filling machines measure a precise volume of product and deposit it into a container. This system is commonly used for liquid or viscous products where an exact dosage is critical.
Advantages:
- Precise Dosage: These machines ensure each container receives the exact same volume of product, providing precise filling.
- Versatility: Suitable for a wide range of products, including high-viscosity liquids, creams, or even pastes.
- Speed: Volumetric filling machines typically offer faster speeds, ideal for high-volume production.
Disadvantages:
- Maintenance: Regular maintenance is required, particularly on the pumps and valves, to ensure accurate dosing.
- Component Wear: Parts can wear out more quickly with abrasive products or those containing solid particles.
2. How Peristaltic Filling Machines Work
Peristaltic filling machines use a pumping mechanism where flexible tubing is compressed by rollers, creating a pumping action that moves the liquid from a reservoir into the container. This technology is especially suited for sensitive products.
Advantages:
- No Direct Contact with the Product: Ideal for sensitive products like pharmaceuticals or foodstuffs, as there is no direct contact with the product, reducing contamination risks.
- Easy to Clean: With fewer moving parts in contact with the product, these machines are easier to clean.
- Precise Dosage: Peristaltic machines also offer precise dosing, especially for lighter liquids and fragile products.
Disadvantages:
- Production Capacity: Peristaltic machines are often slower than volumetric machines, making them less suitable for high-speed production lines.
- Limited to Liquids: These machines are generally suitable for liquid products and are less effective with viscous or solid products.
3. Which Filling system should you choose for your production?
The decision between a volumetric filling machine and a peristaltic filling machine depends on several key factors:
- Viscous or Thick Products: Volumetric filling machines are preferred for denser products, ensuring accurate dosing.
- Sensitive or Sterile Products: Peristaltic filling machines are ideal for these products as they avoid direct contact, reducing contamination risks.
- High-Cadence Production: If you require fast production, volumetric machines are generally more suited.
- Cleaning Requirements: If easy and quick cleaning is essential, peristaltic filling machines offer an advantage.
4. CDA and innovation in Filling Machines
At CDA, we offer filling machines that meet all of these requirements. Our models, such as the K-Net, K-Net Auto, and K-Line S, are designed to provide a flexible solution: they can be used for both volumetric and peristaltic filling, depending on your specific needs. These machines are perfect for a variety of productions, ranging from viscous liquids to more delicate products.
On the other hand, the E-Fill monobloc is particularly suited to peristaltic filling as it is designed for small batches and smaller product sizes, making it the ideal solution for products such as essential oils or cosmetic products.
5. Conclusion: Choosing the best filling machine
In summary, the choice between a volumetric filling machine and a peristaltic filling machine depends primarily on the nature of your products, production speed, and ease of maintenance. If you’re dealing with viscous products and need high speeds, a volumetric machine will likely be your best option. However, for sensitive products or those requiring strict hygiene standards, a peristaltic machine may be more suitable.
At CDA, we provide flexible solutions for all your filling needs, whether it’s volumetric or peristaltic. Feel free to contact us for advice tailored to your production line.
