A brief discussion on the two-in-one concept； The advantages and disadvantages of the three-in-one filter in production

Thread Content

The mainstream two-in-one and three-in-one filters available on the market can be roughly divided into two types: one. The new generation of vertebral-type three-in-one filters was developed based on the older models; it has been in use in the domestic market for only six or seven years. Customers appreciate it because it addresses some of the manufacturing flaws and limitations of the older machines. Its main features are rapid and thorough discharge, a large filtering area, high filtering efficiency, and low manufacturing costs; it effectively addresses the problems associated with old machines, such as residual material remaining after discharge and slow operation. However, since such machines generally last for a decade or so, the new generation of vertebral-type three-in-one models are mainly used for upgrading existing projects, and they are more commonly employed in new projects and new factories; as a result, their market share is not very large. II. The older generation of flat-bottomed types (divided into movable and fixed bottom types) were put into use early on, and they entered the domestic market at the same time. They played a significant role during the period when GMP standards became strictly enforced. The fixed-bottom type is mainly used in industries such as chemicals and pharmaceuticals, in non-sterile environments where the requirements are not very high ； 2. Live workspaces are mainly used in the sterile environments of active pharmaceutical ingredient factories and in settings with stringent production requirements ； Comparing the two: a. Dead-bottom types have relatively lower technical requirements, manufacturing costs, and usage demands, which is why they account for a larger share of the market; however, their operational and maintenance costs are slightly higher over time – for example, manual scraping is required more frequently, cleaning the filter plates is necessary, and replacing them is not very convenient ； b. The costs associated with production at the manufacturing site are high, and the manufacturing requirements are stringent; as a result, the price is relatively high, and there are only a few manufacturers in the market capable of producing it. When using a three-in-one dryer in a live work site, the heating effect is not very significant; it can only serve to retain heat. In summary, when comparing these two methods in a simplistic manner, flat-type three-in-one units suffer from incomplete discharge of material, as well as uneven and insufficient cleaning (to achieve good cleaning results, more time and cleaning solvents are required). Backflow or reverse flushing can lead to problems such as the formation of bulges, high manufacturing costs, oil leakage, and high costs associated with use and maintenance. Let’s discuss and exchange ideas on any issues you encounter when using or manufacturing three-in-one products.
