Drying equipment is one of the important raw material medicines and equipments, and it is widely used in the pharmaceutical field. At present, among the numerous drying equipments, spray dryers are one of the dryers with higher production value, and each set ranges from several hundred thousand to several million. In Wenzhou, Shanghai, Wuxi, Jiangyin, Xining and other places there are a number of professional spray spray dryer manufacturing plant, providing users with hundreds of spray drying equipment every year. From the aspect of research, the research content of spray drying technology occupies the first place in each academic paper of the National Drying Society. The imperfection of theory and the extensive application have always attracted the attention of a large number of researchers.
The drying speed of the spray dryer is fast, and the surface area of ​​the feed liquid after atomization is greatly increased. In the hot air flow, 95%-98% of water can be evaporated instantaneously, and the drying time is only a few seconds, which is particularly suitable for the drying of heat-sensitive materials. . The device has good uniformity, fluidity and solubility, high product purity and good quality. The production process is simplified, the operation and control are convenient, no crushing and screening are required after drying, the production process is reduced, and the product purity is improved. However, the unit's weight and heat consumption are large, and the investment that companies need to make is relatively large, and the average SME cannot afford it.
Therefore, the main measure for reducing the consumption of spray drying equipment is that the energy consumption in the spray drying process directly affects the economic benefits and development prospects of the company. Therefore, industry experts have proposed many measures to save energy and reduce consumption in the spray drying process, through the drying medium. The improvement of thermal cycle and other aspects will further enhance the energy-saving effect of spray drying equipment, reduce costs, increase economic efficiency, and better serve our customers.
The spray dryer has a good drying effect, and the scope of production is also very wide. If we can achieve further breakthroughs in skills and technology will inevitably obtain a broader market space.
