Shanghai Xinzhuang Instrument Co., Ltd. is a leading manufacturer of high-quality, energy-efficient, and environmentally friendly small spray dryers under the LNB brand. As a domestic pioneer in this field, the company offers professional manufacturing solutions that are both secure and cost-effective. Their small spray dryer technology combines advanced engineering with practical application, making it ideal for research and industrial use.
The company has developed an innovative spray freeze-drying system that utilizes cryogenic dehumidification to generate low-temperature, low-humidity air continuously. This process is combined with a specialized atomization device to ensure the continuous drying of liquid into fine ice powder. Additionally, supercritical spray drying technology is being explored as a promising method for producing high-quality powders. By using supercritical fluid technology, researchers have successfully prepared protein liposome powders and compared their properties—such as particle size distribution and morphology—under different drying conditions. The results show that particles produced via supercritical spray drying range from 1 to 60 micrometers, with a spherical shape and smooth surface.
Supercritical fluids have unique properties that make them suitable for various applications, including extraction, drying, and chemical reactions. However, due to their poor compatibility with water, they are not directly applicable for aqueous solution drying. This has led to the development of a new hybrid technique: supercritical fluid spray drying. Although this technology has been studied abroad, there is limited information available in China, making it a promising area for further research.
In terms of simulation and modeling, computational fluid dynamics (CFD) has become a powerful tool for analyzing the complex processes involved in spray drying. With advancements in computer technology, detailed simulations of temperature, velocity, and humidity fields within the drying tower are now possible. These models help researchers understand the behavior of materials during the drying process, including their movement, moisture content, and thermal changes. International studies have focused on improving existing models, developing new drying towers, and exploring horizontal or centrifugal spray drying techniques, as well as large-scale industrial applications.
Shanghai Xinzhuang Instrument Co., Ltd. is dedicated to the research, development, production, and sales of low-temperature experimental equipment and ultrasonic devices. The company employs skilled temperature control engineers and uses state-of-the-art production equipment to ensure high-quality, safe, and reliable products.
