The micro- spray dryer is specially designed for small and high-efficiency spray dryers designed by universities, research institutes, pharmaceutical factories, scientific research departments engaged in medicine (Chinese medicine, western medicine, bio-pharmaceuticals), food and chemical research, in the process of drying. Low noise, fast drying speed, low liquid heating temperature, simple and convenient operation, especially suitable for drying heat sensitive materials. It still retains its original color and aroma, and has good dispersibility, fluidity and solubility. The solvent can directly obtain uniform dry powder, which is labor-saving, labor-saving and hygienic.
Spray drying technology is fast in powdering and drying, and is now being used by a large number of laboratories. In particular, the current domestic micro-spray dryer has been successfully developed, which has greatly reduced the price of the most expensive equipment. The high-end experimental equipment of the past has become the routine equipment of many laboratories, which greatly meets the needs of domestic laboratories. Hot air circulation system. In the process of spray drying, the hot air circulation system is the main power and carrier for drying, collecting and steam discharging. The QFN-8000T and QFN-8000S models produced by the company adopt a vacuum suction method to circulate hot air in the system.
Its advantages are:
1. Cyclone Collection System The cyclone collector is a very classic powder collector and is widely used in micro spray dryer systems. Its structural shape directly affects the collection rate of the powder and plays an important role in the spray dryer. For the spray dryer system, the performance of the cyclone collector often depends on the actual operation observation and experimental results, so the most reliable way to purchase the spray dryer is to test it yourself.
2, the hot air is controlled in the system, no leakage, will not affect the experimental environment, so that the experimental staff work in a clean experimental environment. In the import of other brands and other domestic brands, the positive pressure blown-in hot air circulation system is widely used. Because the positive pressure is generated inside the system, the pressure of the hot air leakage is implied at each joint of the spray drying system. Therefore, because the hot air containing dust leaks out of the laboratory, it is not suitable for the work requirements of laboratory personnel. It has been confirmed by experiments that the vacuum suction type hot air circulation system is matched with the reasonable cyclone collection system. The collection rate of the micro spray dryer sample results is more than 10% higher than that of the positive pressure blown spray dryer, especially in the experiment of micro sample. The result is more obvious.
3, liquid material atomization system In the spray dryer system, the atomization nozzle is a vital component, usually available in 0.7mm, 1.0mm, 1.4mm, 2.0mm four aperture nozzles. The price of the spray dryer is based on different materials and solutions. The choice of nozzles should be selected after consultation with the product experts or after the experiment. Shanghai Qiaofeng Industrial Co., Ltd. provides the service for the user to test spray or give the user a trial, in order to make the user buy the most suitable. The product. The experimental process of spray drying is to achieve a complete set of processes for the successful drying of a certain material. Each experimental parameter is part of the whole process, including the selection of nozzles, so the manufacturer is very important to the user's technical guidance, and friendly technical support will greatly help the user's experimental success.
