Description

Technical Field

[0001] The invention relates to the technical field of spray drying devices, in particular to a high-speed centrifugal spray drying machine with a vortex supercharging function. Background Art

[0002] The scientific name of pandanus is Pandanus odoratus, which is the fresh leaves of Pandanus odoratus of the Pandanus genus. It is also known as pandan leaves and pandan fragrance. It is a perennial tropical herbal spice plant. The pandan introduced from Indonesia in the 1950s was successfully trial-planted in Xinglong Farm in Wanning, Hainan. Wanning became the birthplace of my country's pandan industry. Today, it is grown in Hainan, Guangdong, Yunnan, Taiwan and other provinces. The suspension of pandan leaves after pulping and homogenization is used to prepare pandan pure powder. Spray drying technology is generally used to prepare pandan pure powder.

[0003] Spray drying is a widely used technology in the drying industry. It atomizes liquid materials into tiny droplets and makes them contact with hot air, thereby quickly drying them into powder or granular products. The working principle of the spray dryer mainly involves atomizing liquid materials into tiny droplets through a nozzle. These droplets quickly evaporate water in the hot air, thus completing the drying process in a very short time. This process is not only suitable for liquid raw materials such as solutions, emulsions, suspensions, but also can handle liquid materials with a certain viscosity, making spray drying one of the most widely used processes in the drying industry.
