How does a small laboratory spray dryer get fluidity?

　　Many plant extracts, such as traditional Chinese medicine and other natural products, need spray drying process when extracting and processing. However, for a long time, the spray drying of natural products extracts and fruit juice from laboratory Chinese medicine (Chinese herbal medicine) is a major problem for researchers. According to the author's understanding, the conventional laboratory spray dryer is used for spray drying of natural products extract and fruit juice in laboratory Chinese medicine (Chinese herbal medicine), because the material itself contains a lot of carbohydrates, which are easily melted at high temperature and stick together in spray drying for a short time. The stuff like sugar is glued to the wall of the drying chamber of the spray dryer, so that researchers can not get the powder with good fluidity. In order to solve this problem, researchers have tried many ways to add a lot of excipients, such as starch and cyclodextrin, in order to get the powder, but the effect is not very satisfactory. Therefore, it is necessary to upgrade and upgrade on the basis of conventional laboratory spray dryer.

　　It is learned that Anhui inno Engineering Technology Co., Ltd., adhering to the aim of innovation for many years, has developed a new generation of laboratory small spray dryer (suitable for Chinese medicine and fruit juice) on the basis of small spray dryer in the laboratory. The spray dryer for Chinese medicine (Chinese herbal medicine), natural products extract and fruit juice, etc., at 110 ° Under the condition of low temperature, the powder particles with excellent fluidity were obtained.

　　The laboratory spray dryer is developed for research, small and medium scale liquids such as concentrated liquid, extraction liquid and diluent. The advantages of laboratory spray dryer are automatic operation and integral frame structure. The drying speed is fast, and the surface area of the material is greatly increased after atomization. The water content of 65%-98% can be evaporated instantaneously in the hot air flow. The product has uniform particle size, fluidity and instant solubility, and the product has high purity and good quality. It is especially suitable for drying heat sensitive materials, and can ensure the color, fragrance and taste of materials.

　　In addition to the use of Chinese medicine and fruit juice industry, the scope of use of spray dryer is widening. At present, the equipment is improved and upgraded for different needs in the market. For example, in view of the difficulty of drying organic solvents in spray drying machines, the general organic solvents will be inflammable and explosive, and the emergence of the closed type laboratory spray dryer will avoid this problem, so that the materials can be circulate in the closed drying system, and the whole system is full of inert gases (such as nitrogen or argon). It can avoid the contact between organic solvent gas and external oxygen, and ensure the safety of production.

　　With the development of society and the progress of science and technology, spray dryer equipment is also moving towards automation and intellectualization. The realization of automatic control of small spray dryer can help to reduce the labor intensity of workers, reduce the increase of production and improve the quality of food and medicine. For example, in the process of making powder, the automatic spray dryer can process the key data such as inlet and outlet air temperature, air volume, mud pressure and moisture in the spray dryer by processing software, analyze the factors that cause the system changes in real time, and simulate the manual operation to adjust the temperature of the hot stove and the feed flow rate, so as to replace the manual operation, and achieve the convenient and safe effect.
