It is understood that a filter machine is a device used in industrial production to separate solid and liquid mixtures. Different filter materials, such as metal mesh, paper, sand layers, and other porous materials, are usually selected as the filter layer to allow the mixture to pass through, blocking the solid material on one side of the filter layer while the liquid flows out through the gaps in the filter layer, achieving the purpose of separation. Filter machines are widely used in industries such as pharmaceuticals, food, and chemicals.
Filter machines are divided into three categories based on the method of obtaining filtering driving force: gravity filters, vacuum filters, and pressure filters.
It is reported that as early as the 1920s, China began to apply filtering technology, but at that time, the filtering technology was not mature enough and the application scope was relatively small. After decades of development, in the 21st century, China's filtration technology has achieved breakthrough development under the promotion of high-tech, and now it has been applied to various industries, with certain development space. However, there are still many industrial chains in China, with low production concentration, low research and development capabilities for high-end products, and low manufacturing technology levels in the filter industry. The import and export trade deficit continues to expand.
Compared with the international level, there is still a certain gap in the development of filter machines. It is understood that China's filtration equipment manufacturing industry is still in the development stage, and there are few new technologies domestically, so it can only rely on foreign imports. It can be said that the road to localization of high-end filter machines is exceptionally bumpy. With the increasingly severe environmental pollution problem, the demand for filter machines has become stronger. At the same time as the pharmaceutical industry has higher requirements for the quality of filter machines, it has also prompted filter equipment manufacturers to upgrade their products, and inferior products will gradually be launched into the market. Experts believe that there will be major changes in filtering equipment in the next five years, not mainly in technology, but in the integration of market size, market demand, management systems, and other aspects.
Some companies that win the market with low prices will find it increasingly difficult to establish themselves, and high requirements such as pharmaceutical water quality will cause them to withdraw from the filtration equipment industry and engage in other industries. Other technologically backward and small-scale enterprises will also be ruthlessly eliminated, and the overall number of enterprises will remain basically unchanged. New entrants will replace those eliminated enterprises, but overall this number will show a downward trend.
Overall, the filtration equipment industry is facing a new golden period of development. In the process of rapid growth, there will inevitably be survival of the fittest, which is a market game rule but also an opportunity for enterprise development.
To make new breakthroughs in the filter industry, filtration equipment manufacturing enterprises need to base themselves on the market, establish reasonable management systems, enhance research and development capabilities, and produce high-tech products to meet market demand, promote green, circular, and low-carbon development in the pharmaceutical industry, and improve the overall energy-saving level and international competitiveness of energy-saving industries.
