Spray equipment market, heavy volume spray dryer, six advantages highlight
Spray drying is a method applied to the drying of materials. It can dry the solution, emulsion and suspension into powder or granular products, eliminating the steps of evaporation and pulverization, and is widely used in the pharmaceutical industry. According to industry data, the total market size of global spray dryers in 2017 was US$1.068 billion, which has grown steadily in recent years. According to the analysis, the market is expected to reach US$1.611 billion by the end of 2025. As a big country in pharmaceutical machinery and equipment, China will also have good opportunities in the global spray dryer market.
There are many types of spray dryers. Among them, the experimental low-temperature spray dryer and its main application in universities, research institutes and food and pharmaceutical chemical enterprises to produce micro-particle powder, broad-spectrum applicability to all solutions such as emulsions and suspensions, laboratory low-temperature spray drying The machine is dried in a vacuum environment to achieve instantaneous drying of the material under low temperature vacuum, providing a convenient and safe drying method for the heat sensitive material.
Compared to high temperature spray dryers, low temperature spray dryers offer several advantages. The relevant technical personnel introduced.
First, the drying speed is faster. The low-temperature spray dryer has a fast drying speed*, and after the spray liquid is sprayed, the surface area is large, and in a high-temperature air stream, it can be evaporated instantaneously.
Second, the temperature of the droplets in the low-temperature spray dryer is not high during the drying process, and the product quality is good. According to the industry, the temperature range used for low-temperature spray drying is very wide (80-800 degrees). Even with high-temperature hot air, the exhaust air temperature is not very high. In the early stage of drying, the material temperature does not exceed the wet bulb humidity of the surrounding hot air. The quality of dry products is good. For example, defects such as protein changes, vitamin loss, and oxidation are not prone to occur, and the quality of heat sensitive materials, organisms, and drugs is substantially close to the standard for drying under vacuum.
Third, the low temperature spray dryer has good dispersibility, fluidity and solubility. It is reported that since the drying process of the low-temperature spray dryer is completed in the air, the product can basically maintain a spherical shape similar to the droplet, and has good dispersibility, fluidity and solubility.
Fourth, the spray dryer production process is decomposed and the operation and control are convenient. Low-temperature spray drying is usually used to treat solutions with a moisture content of 40%-60%. Even if the moisture content is as high as 90%, the special material can be dried into a powdery product at the same time without concentration. Most products do not need to be pulverized and screened after drying, which reduces the production process and simplifies the production process. In addition, the particle size, bulk density and moisture of the product can be adjusted within a certain range by changing the operating conditions, and the control and management are very convenient.
Fifth, prevent pollution and improve the production environment. Since low temperature spray drying is carried out in a closed drying tower, this avoids the drying of dry products in the workshop. For odor materials, the production process of closed circulation system can be used to burn off odor, prevent air pollution and improve the production environment.
Sixth, the low-temperature spray dryer is suitable for continuous large-scale production. Spray drying can meet the requirements of large-scale industrial production. The dry product can be continuously discharged, and combined with cooler and wind power for post-processing, forming a continuous production line. .
It can be seen that the advantages of low-temperature spray dryers are obvious, which can bring a lot of convenience to the pharmaceutical industry. However, with the continuous improvement of the requirements of the pharmaceutical industry, low-temperature spray dryer enterprises also need to continuously improve and upgrade equipment. For example, some users have reported that low-temperature spray dryers contain problems in the drying of organic solvent materials in spray drying, and all require manufacturing companies to explore and break through.
