Capsule Metal Detector

Capsule MetalDetector has been designed to detect the presence of metallic parts in capsules and tablets. Such detectors can also sense the presence of trace quantity which surely will degrade medicines, drugs and nutrients. The adverse effect of the presence of even the smallest quantity of metal can be explained with an example. Vitamin C, commonly known as ascorbic acid, can be degraded because of just a trace amount iron and copper. The degradation of the drug quality may happen because of metal contamination in the manufacturing of capsules and tablets.

Capsule Metal Detector helps in detecting the ferrous and non-ferrous metal particles that may contaminate capsules. It is critical to detect all impurities before the final packaging of medicines otherwise that will cause harm to consumer and will lead to their dissatisfaction. Not only the presence of impurities harmful to consumers but also may lead to damage of machinery. That is the reason like other industries, such as chemical, coal, food, ceramic, mineral processing rubber and plastic, pharmaceutical industry also requires metal detectors for full consumer protection and safety to their health.

The metal detectors used in pharmaceutical industry can detect both magnetic and non-magnetic metals. Inside the machine there are transmitters and receiver equipped that perform the task of detecting and rejecting metallic particles. The machine creates an electromagnetic field which if interfered by even the smallest metal particle, the transmitter gets activated and send signal to the receiver. The receiver then send signal to the metal rejecter equipment fitted in the machine. The rejected capsules are then separated from the main production line.

Working Principles of Different Metal Detectors

Metal detectors used in pharmaceutical and food industries operate on different working principles. Discussed below is working principal of different types of metal detectors:

Balanced coil metal detector a in this type of metal detector the working principle is based on balance of current flow in three different coils. These three coils are transmitter, receiver and detector. The transmitter coil generates an electromagnetic field in which if a metal particle passes, the electromagnetic field gets disturbed sends a signal to the receiver. The receiver diagnoses the particle and finally it is detected by the third coil. The response is contingent on magnetic and conductive properties of the metal. In this detector, the control system is usually fixed atop the search head or remotely situated. Therefore, when a metal particle renders the system to illuminate, the signal at the receiver is reckoned as one millionth of a volt. The signal is initially amplified by a highly efficient RF amplifier, and then modulated down to lower frequency. In the end, the signals are digitally processed to maximise the sensitivity.

Magnetic field metal detector a this type was used for only detecting ferrous metals, like iron and steel. But with design modification, this machine can detect non-ferrous metals in medicines, drugs and foods as well. The working of this machine entails that when a magnetic particle goes under the detector, a current is produced which is amplified by the electronic control mechanism of the detection system. The same electronic control system is employed to trigger the detection of signal output. In case of non-ferrous metal particles, the conductive material when interfering in the magnetic field it produces signals for non-magnetic metals, which is ultimately detected by the detector. But in the second only large pieces of nonferrous metals are detected. Therefore, this technology is mostly used for ferrous metals detection.

Pulse induction metal detector a Pulse induction metal detector employs electromagnetic induction. It contains on ore more induction coils which interact with metallic elements on the ground. The pulse induction detector is receptive to both ferrous and non-ferrous particles. The detector is very sensitive to rings, coils and other small things. In a typical pulse induction metal detector, 100 pulses per second are sent to the receiver which alerts the detector to isolate the contaminated medicines or drugs.
