Main features and functions:
1) Metal detection: High-frequency detection (0-800kHz), suitable for detecting and removing magnetic and non-magnetic metallic foreign substances in tablets, including fine metal shavings and metal screen wires embedded in the tablets, ensuring the purity of the medicine. The detection coil is made of stainless steel and is completely sealed inside, featuring high precision, high sensitivity, and high stability.
2) Sieving and dust removal: Effectively removes dust from tablets, removes burrs, and raises the height of the tablets to ensure a clean surface.
3) Human-machine interface: The sieving and metal detection share a touch screen for operation. The intuitive interface provides a convenient user experience and supports password-based hierarchical control and performance confirmation procedures. The equipment can record 100,000 events and store 240 product parameters, facilitating quick replacement. The touch screen supports PDF data export and electronic signature, meeting the requirements of FDA 21CFR.
4) Automatic learning settings: Utilizing the latest microprocessor control system, it has product tracking and automatic learning setting functions, and can make internal adjustments and compensations according to changes in product effects, ensuring detection accuracy and ease of operation.
5) Seamless elimination structure: Integrated injection molding design, without hygiene dead corners, no tool disassembly, convenient cleaning, in line with hygiene standards. The flip plates of the upper and lower structures realize rapid automatic elimination, minimizing material loss and not interfering with normal production.
6) Power-off protection and waste management: The elimination device remains open during power failure (optional), ensuring safety. The waste outlet can be connected to a collection bottle for convenient collection and handling.
7) Fully transparent working area: The working area adopts a fully transparent design, making the running route of the tablets clear, facilitating observation.
8) Quick disassembly design: The entire machine adopts a quick-connect method, requiring no tools, and can be disassembled within 5 seconds, with simple operation.
9) Product area and mechanical area separation: The working area of the sieving machine and the mechanical area are completely separated, ensuring that the product and mechanical components do not interfere with each other, enhancing product safety.
10) Sieve body design: The surface of the sieve body track is flat, mirror-polished, and the edges of the sieve holes have no burrs, which will not damage the tablets. The equipment sieve body adopts a stack design, with adjustable discharge height, suitable for different production needs.
11) 360° rotation: The sieve body supports 360° rotation, providing greater flexibility, and can be connected to any outflowing tablet press machine for online operation, optimizing production space and adapting to various production scenarios.
12) New drive device: The upgraded drive device is larger, runs more stably, and has lower noise, meeting high-performance standards. The upgraded design enables the tablets to automatically flip on the sieve body track, significantly improving dust removal efficiency.
13) Speed adjustable: The sieving machine's running speed is adjustable without any limit, meeting the requirements of different tablet types, speeds, and out-of-tablet quality.
14) Height adjustment and mobility: The overall height of the equipment can be adjusted, and it is equipped with lockable casters, facilitating movement and precise positioning.
15) Compliance materials: The metal parts in contact with the tablets are made of 316L stainless steel with mirror polishing; other metal parts are made of 304 stainless steel; non-metal parts in contact with the materials comply with food-grade requirements, ensuring durability and ease of cleaning. All components in contact with the tablets comply with GMP and FDA requirements.
16) Certification and compliance: The equipment meets HACCP, PDA, GMP, and CE certification requirements, providing certification documents, and supporting challenging tests.
Key factors affecting the detection range
In addition to the hardware parameters mentioned above, the following factors can also affect the actual detection capability of the device:
Foreign object type:
The device is most sensitive for detecting iron (Fe) because it has the strongest magnetic properties.
The detection challenge for stainless steel (SUS) is the greatest, especially non-magnetic 316L stainless steel, so its detection accuracy value is usually higher than that of iron (such as 0.4mm).
Product Features
The size, moisture content, and density of pills can produce a "product effect" that may interfere with the detection signal. Advanced equipment has an "automatic learning" function that can compensate for this interference.
Equipment technology:
High frequency detection technology: It is crucial for detecting small non-ferrous metals and stainless steel, and can significantly improve sensitivity.
Balanced coil design: can effectively suppress external vibrations and electrical noise, ensuring stable detection
In general, the bottom line of the detection range for a tablet deduster and metal detector monoblock machine is:
Types that can be detected: iron, non-ferrous metals (copper, aluminum, etc.), stainless steel.
Sizes that can be detected: Small metal particles with a diameter of 0.3mm to 0.4mm can usually be stably detected.
Some high-end or specific models of equipment, such as Ruijinqi and Anli, can even achieve an accuracy of 0.2mm under optimal conditions.
I hope this detailed parameter comparison can help you evaluate the equipment more accurately. If you are interested in equipment from a specific manufacturer, I can help you find more specific information.
Is the technology infrared spectroscopy
I have read 7 web pages
No, the core technology of the metal detection screen integrated machine is not infrared spectroscopy, but balance coil technology based on electromagnetic induction principle.
Simply put, its detection principle is similar to airport security gates, mainly detecting metal impurities in pills through high-frequency electromagnetic fields.
Core Technology: Balanced Coil Technology
The core of the device is three carefully wound detection coils: a transmitting coil and two receiving coils.
Establishing a high-frequency magnetic field: During operation, the central transmitting coil generates a high-frequency electromagnetic field (usually between 300kHz and 800kHz).
Maintain signal balance: The electrical parameters of the left and right receiving coils are completely consistent. When no metal passes through, the signals they generate cancel each other out, and the system determines it as' normal '.
Breaking the balance, triggering an alarm: When a pill containing metal impurities passes by, the metal particles will interfere with the magnetic field, causing the signals of the two receiving coils to no longer be balanced. Once the system captures this small change, it will immediately trigger the removal device to blow the unqualified pills into the waste channel.
