Three Types of Metal Detector

Metal contamination is a major quality risk in pharmaceutical production,such as tablet press or capsule filling. Choosing the right metal detector ensures compliance, product safety, and efficient production.

In this article,we will introduce standalone detectors, integrated systems (e.g., capsule polishers or tablet dusters with metal detection), or OEB-level high-containment solutions to meet different production and safety needs.

Why Metal Detection Is Critical in Pharmaceutical Manufacturing

1. Risk of metal contamination during compression, filling, polishing
2. GMP / FDA / EU compliance requirements
3. Product safety & brand protection

Overview of the 3 Common Metal Detector Solutions

1.Standalone Metal Detector

It is easy to move,and it can work for both tablet press machine and capsule filling machine.Suitable for different product production,save cost.But need time to connect with capsule polishing or tablet de-duster.

2.Integrated Machines (Capsule Polishing & Metal Detector / Tablet Duster & Metal Detector)

It can work with tablet press machine,reduces material handling and labor,Ensures continuous product quality monitoring,save installation time and space.

It can work with capsule filling machine,reduces material handling and labor. Ensures continuous product quality monitoring,save installation time and space.

3.OEB-Level Metal Detectors

OEB (Occupational Exposure Band) metal detectors are designed for high-containment environments, used for Highly potent APIs or Cytotoxic or hazardous compounds. It is fully enclosed design with CIP cleaning capability. And ensures protection for operators while maintaining product integrity.

Choose the Right Metal Detector Using Comparison Table

Type	Typical Use	Integration	Advantages	Limitations
Standalone	Tablets, capsules	Minimal	Cost-effective, easy maintenance	Limited line integration
Integrated	Capsule polishing / Tablet duster	Medium	Saves space, reduces handling	Higher initial cost
OEB-Level	Highly potent APIs	Full	Operator safety, regulatory compliance	Complex, requires training

9.Brush is easy to clean and installation,as it is separate with the shaft.

FAQ about metal detectors

1: What is the difference between standalone and integrated metal detectors?

Standalone metal detector need to connect with capsule polishing machine or tablet de-duster. It need more time for installation and labor. Integrated metal detectors combine polishing or dusting with metal detection, saving space and reducing material handling.

---

2: Why are OEB-level metal detectors important?

OEB-level metal detectors provide full containment for highly potent APIs or cytotoxic compounds, ensuring operator safety, product integrity, and compliance with high-containment regulatory standards.

---

3: Can metal detectors be integrated with existing capsule or tablet equipment?

Yes. we need to know the product outlet height of capsule filling machine or tablet press machine.

5: How often should metal detectors be tested in pharma production?

Regular verification with certified test pieces is recommended according to GMP, FDA, and EU guidelines. Testing frequency depends on line speed, product type, and regulatory requirements.

Phần kết luận

Each type of metal detector serves different production and safety requirements. Standalone units are ideal for simple lines, integrated machines combine efficiency with detection, and OEB-level systems provide high-containment protection for potent compounds.
