Drug safety has always been an important issue of concern for pharmaceutical companies, and the tablet metal detection machine is one of the very important detection equipment in the production process of pharmaceutical companies. Today, the editor will take you to understand the working principle and process flow of the drug metal detection machine.
The working principle of the tablet metal detection machine is based on the principles of electromagnetic induction and conductivity. The principle of electromagnetic induction is to use a metal conductor to generate induced current under the action of a constant magnetic field. When the conductor is matched with the rear of the detection machine, this induced current forms a slight oscillation inside the detector, causing the alarm light to light up. Suitable for detecting non-magnetic metals such as copper, aluminum, gold, silver, etc. The principle of conductivity is to use the different electrical conductivities of conductors at different currents to detect the electrical properties of conductor materials. Suitable for detecting magnetic metals such as steel, steel nails, and iron filings.
The process flow of a tablet metal detection machine generally includes the following steps:
1. Needle sensor detection
Needle sensor is one of the most critical components of tablet metal detection machine. Firstly, the pills are randomly arranged, usually passing through around two thousand pills per minute. When the tablet passes through the metal detector, the needle sensor will automatically detect the metal content in the tablet. If the metal content in the pill exceeds the standard, the needle sensor will automatically remove the sample.
2. Calibration of metal detection machine
The calibration of the tablet metal detection machine is a very important step, which can ensure the accuracy of the metal detection machine. During the calibration process, the metal detector will automatically scan the standard metal unit. If the scanned metal content is consistent with the content of the standard metal unit, it indicates that the metal detector is working normally. If the scanning results deviate from the content of standard metal units, adjustments need to be made.
3. Data analysis and recording
The tablet metal detection machine can automatically export tablet data, and pharmaceutical companies can use data analysis to determine whether the metal content of drugs meets the standard. At the same time, pharmaceutical companies also need to record information such as drug batches, testing times, and testing machine values in order to trace drug quality issues.
