At present, China's spray drying industry has a certain enterprise and production scale, and has been widely used in medicine, food, chemical industry, university scientific research and other industries. However, with the continuous improvement of the times, the country's requirements for the quality of pharmaceuticals are getting higher and higher.Spray dryerManufacturers still have to absorb foreign advanced technology to improve product quality, and according to the requirements of high quality, low energy consumption, environmental protection research. And adjust the product structure to meet production needs. In recent years, the development trend of spray dryer at home and abroad mainly has the following trends:
OneThe combination of several heat transfer forms makes them have the advantages of various heat transfer forms in different stages of spray drying and makes the equipment more reasonable.
TwoLarge scale development of equipment. Enlargement technology of spray drying equipment can ensure large-scale production, and large-scale research is one of the development directions of spray drying equipment in the future.
ThreeSpray drying equipment specialization. Spray drying equipment is a well-known non-standard equipment. Non-standard equipment is mainly processed materials and product requirements vary greatly, so there is a real design spray drying equipment can play its role, from technical to economic, it has a certain significance.
FourDevelopment of multistage and combined spray drying system. Different typesSmall spray dryerIt can be applied to different materials or spray drying stages that can be applied to different materials. Combined spray drying can optimize spray drying process and make spray drying system more reasonable.
FiveAnd the versatile nature of the equipment. Today's spray drying equipment is not limited to spray drying operations, sometimes crushing, grading, or even heating a machine reaction, greatly shortening the production process, making the equipment versatile.
Spray dryer has good uniformity, fluidity and solubility, high purity, good quality, simplified production process, easy operation and control. The air of the spray dryer is filtered and heated to enter the air distributor at the top of the dryer. The hot air enters the drying chamber evenly with a spiral shape. In the hot air flow,Ninety-five％-98% of the water can be evaporated instantaneously, and the drying time is only completed. It takes a few seconds, especially for drying of heat sensitive materials. However, in the production process, spray drying equipment still has certain limitations. For example, if the exhaust temperature of the spray dryer is too high, the color of the material will become dark, and in serious cases, the material will change color or even degenerate. It is more common in the production process. Therefore, with the rapid development of China's pharmaceutical industry and stricter national requirements for drug quality, enterprises need to constantly carry out technological innovation, strive to upgrade equipment, promote intelligent, multi-functional, professional and large equipment.-Scale development and other directions. For example, in practice, the method of programmable frequency conversion feeding is introduced, which can stabilize the exhaust temperature and reduce waste.
How can we avoid losing the original form and characteristics during drying?
Our company develops a set of products based on many customer feedback.Laboratory vacuum cryogenic spray dryerThe temperature of the device is80-100Keep the sample dry and keep the original characteristics perfectly. You can also customize different temperatures according to customer requirements.
