The Pressure Spray Drying Granulator is a high-performance industrial drying system that employs pressure atomization technology. Using a diaphragm pump to generate pressure, it disperses liquid feed (solutions or slurries) into fine droplets, dramatically increasing material surface area for rapid heat exchange with hot air. This process achieves complete drying within seconds, producing superior quality powder or fine particle products for diverse industrial applications.
Among the YPG-I series, the YPG I-70 model stands out as a mid-capacity, highly efficient solution ideal for medium-scale production environments where precision, reliability, and energy efficiency are key. With a water evaporation capacity of 70 kg/h, it offers optimal throughput for applications such as pharmaceutical intermediates, food additives, biochemicals, and specialty chemicals.
Key features of the YPG I-70 include:
Compact footprint: Overall dimensions of 6×4×12 m, making it suitable for facilities with limited space
Tower diameter of 1400 mm, providing excellent residence time and uniform drying conditions
Flexible heating options: Can be configured with steam + electric heat supplement or oil/gas-fired hot air furnace, allowing adaptation to different utility setups and thermal requirements
High-quality output: Produces spherical particles with consistent size, good flowability, and low residual moisture—ideal for downstream processing such as packaging, blending, or granulation
Compared to smaller models (e.g., YPG I-25), the YPG I-70 delivers significantly higher capacity while maintaining ease of operation and automation. It also offers better scalability than larger units (e.g., YPG I-100+), making it a cost-effective choice for pilot-to-commercial scale production.
With its robust design, simple control system, and ability to handle heat-sensitive materials, the YPG I-70 is a versatile and reliable workhorse in modern drying operations.
