Patent US5792984A

Patent US5792984A describes a process for making a stable, uniform powder from oil-based substances, such as pharmaceutical or food ingredients. It involves forming a thin layer of the liquid onto a solid surface within a vacuum chamber, then rapidly drying or removing the solvent to produce a fine, dry powder. This method helps preserve the product's properties, prevents clumping, and results in a high-quality powder suitable for various applications. Essentially, it’s a technique to efficiently convert liquids into stable powders while maintaining their quality.
