The NBP-2000 laboratory low-temperature NBPray dryer is specially designed by Nanbei for heat-sensitive materials. The rapid drying of heat-sensitive materials has always troubled researchers. Generally, vacuum drying and spray drying have great damage to the biological activity or structure of the material. Freeze drying is time-consuming and inefficient, and the dried material is bulky and requires secondary grinding. On the basis of long-term contact with scientific researchers, Nanbei company realized that low-temperature spray dryers can effectively help scientific researchers solve the difficulties of drying heat-sensitive materials, and specially developed the NBP-2000 laboratory low-temperature dryer.
