Vacuum rake dryers manufactured by Changzhou Changhai Drying have been exported to a large-scale fine pharmaceutical enterprise in Vietnam, dedicated to low-temperature vacuum drying of high-viscosity pharmaceutical paste intermediates, biological APIs and heat-sensitive chemical materials.

Paste pharmaceutical materials feature high viscosity, easy wall adhesion and thermal decomposition under high temperature. The dual-shaft opposite rake teeth continuously scrape and flip materials, completely solving wall sticking, caking and uneven drying problems. Adopting 316L pharmaceutical-grade mirror-polished stainless steel, the equipment has no sanitary dead corners and is easy to clean and disinfect. Fully sealed negative pressure operation avoids dust leakage and cross-contamination, fully meeting GMP clean production standards.

Equipped with low-temperature vacuum drying technology and solvent condensation recovery system, the equipment realizes energy-saving, eco-friendly and compliant production. All equipment has passed export inspection and IPPC fumigation packaging. We provide customs clearance coordination, on-site commissioning, technical training and long-term after-sales spare parts support, helping overseas pharmaceutical factories achieve standardized and compliant API production and export.
