Centrifugal atomizer is suitable for drying heat-sensitive substances such as biological products, biopesticides, and enzyme preparations. Because the ejected materials are only exposed to high temperatures when they are sprayed into mist particles, they can only be heated instantaneously, which can prevent these active materials from being damaged after drying. Therefore, many chemical industries will choose to use centrifugal atomizer when producing products. So what issues should we pay attention to when using centrifugal atomizers?
1. Requirements to ensure the cleanliness of Centrifugal Atomizer
Some of the main processes in the processing of Centrifugal Atomizer need to be carried out in a 100,000-level clean environment. Spray drying and spray drying are important processes for quality control. In order to ensure the quality of drugs, the parts in contact with materials of the centrifugal atomizer should be made of stainless steel, and 316L stainless steel should be used for highly corrosive materials. The drying chamber, cyclone separator, filter and other parts that directly contact the material have smooth inner walls and no dead corners, making them easy to disassemble and clean.
Because the internal system of the centrifugal atomizer is relatively large, it cannot be placed in the clean area as a whole. It often only collects part of the materials in the clean area. In this case, the system is required to have good sealing performance to prevent the system from external contamination.
2. Avoid sticking to the wall
In the spray drying process of centrifugal atomizer for solid preparations (especially traditional Chinese medicine), adhesion phenomenon is a serious problem, which will hinder the normal operation of the centrifugal atomizer. Materials stuck to the wall are not conducive to collection operations and over time, sensitive wall-glued materials can deteriorate into substandard materials. From a process perspective, solutions include selecting appropriate solvents, adding auxiliary materials, and changing process parameters, but these methods do not have much room for adjustment, so we need to seek fundamental solutions from an equipment perspective.
The actual operation process of a centrifugal atomizer is actually divided into several steps:
First, when the liquid product is fed into the centrifugal atomizer, the high-speed flow channel in the atomizer will atomize the liquid, thereby converting the product into a state of solid-liquid mixed particles.
In the second step of the centrifugal atomizer, the atomized particles are directed to a drying chamber with controlled temperature and air flow, where the hot air will evaporate the liquid in the particles. In order for the final product to meet the standards, the contact time between the particles and hot air needs to be appropriate to maintain a certain moisture content of the powder; at the same time, the state of the drying chamber should also be well controlled, because the volume and air flow of the drying chamber will affect the nutrition of the product.
The third step is the final step in the process, where the powder in the air stream is collected through a separator in the Centrifugal Atomizer into a container so that the final product can be packaged or mixed with other ingredients.
