Development status of foreign tablet presses

Equipment remote monitoring and remote diagnostic techniques are also emerging. Computer-controlled tablet presses are beginning to be widely used in pharmaceutical companies, remote monitoring and remote diagnostic systems for tablet presses. With the rapid development of computer, broadband, virtual and other computer high-tech. The remote monitoring and remote diagnostic technology has made use in the tablet press industry. At present, remote monitoring and remote diagnosis functions are widely available on advanced tablet presses in developed countries. The establishment of such a system is also to achieve a network dialogue between the center (servant) and the tablet press user (user) via the Internet, so that the service party can understand the fault of the user tablet machine through the Internet and the tablet press is executing. The working state of the command, in turn, judges the failure of the tablet press and proposes a feasible solution. Through the establishment of the remote monitoring and remote diagnosis system of the tablet press, the fault can be eliminated in real time, which greatly improves the after-sales service response capability and speed of the tablet press manufacturer, and also improves the economic benefits of the enterprise. The remote monitoring and remote diagnosis system of the tablet press should include personnel equipment, network construction, hardware facilities, software selection, etc., to complete the fault monitoring, analysis, feedback, release and real-time solution services to ensure the entire system. Effective operation. At present, the world's major tablet press manufacturers already have a tablet press with an output of 1 million pieces per hour. High-speed and high-yield is the goal that tablet press manufacturers have been pursuing for many years. Reduce cross-contamination as much as possible. The granules for tableting enter the hopper through the closed barrel and the closed conveying system, and the sealing property of the tableting process and the isolation of human flow and logistics. The sealing performance of the input and output of foreign tablet presses is very good. In the process of tableting, effective measures are taken to prevent dust flying and granule stratification. The pressed tablets enter the packaging process through sieves, in-slice detection, metal detection, etc., and the whole process is quite closed. However, most of the tablet presses in the country are closed or not completely sealed, and the process of breaking causes the dust to fly between the tablets. With the in-depth implementation of GMP, the tightness of the tableting process and the isolation of people and logistics are particularly important. This is the basic function that must be possessed in the design and manufacture of manufacturing equipment. The user equipment usage interest is greatly reduced. Improve the cleaning function of the tablet press, and clean the WIP bit to clean the tablet press. In addition to the design of the full consideration of the local cleaning, the cleaning function of the tablet press emphasizes the detachability, only convenient and quick disassembly, to ensure the clarity and completeness. Both German and British tablet presses have this function. With start, end and speed adjustment. With this option feature, control technology is connected to the entire production line. A tablet press can be connected to a production line. It can be reliably and automatically connected with other equipment of the production line, such as sieve, vacuuming, detecting, conveying, barreling, etc., to simultaneously complete the pressing production task of the tablet. At the same time, different monitoring methods are also used on the external equipment to provide high safety and reliability. The on-line detector can be used to remove burrs, flash and dust from the pressed tablets. The vacuum monitoring function uses a flow monitor to periodically detect the suction pressure at a specified position in the suction pipe. Continuously compare the set value with the measured value. If the detector does not detect the suction pressure (no flow) in the suction pipe 10, the tablet presser will give a fault alarm and stop running. This function greatly guarantees the reliability of production and can continuously remove the dust during the production process of the tablet. The control technology connected to the entire tablet production line is a new technology for tablet production control, and the future development trend. This technology has just started in China.
