• Oxygen-free processing environment: By eliminating oxygen from the drying medium, the system helps prevent oxidation and quality deterioration, making it suitable for heat-sensitive and oxidation-prone materials.
• Steam condensation and heat recovery: Condensed exhaust water can be recycled, helping reduce wastewater discharge. A multistage steam-compression heat pump recovers secondary steam, raises its temperature, and returns it to the process. The system's overall energy consumption can be reduced by 20% compared with conventional processes, according to Longxin's technical data.
• Intelligent temperature-gradient control: Multizone temperature control and intelligent adjustment of steam flow and atomization pressure enable precise management of successive drying stages, from rapid moisture removal to particle solidification and surface treatment.
• Integrated spray drying and fluidized-bed technology: A dynamic fluidized bed at the bottom of the drying tower promotes particle coating and densification through gas-solid interaction, helping improve bulk density and powder flowability.

3. High-Efficiency Fluidized Bed Dryer

Developed for continuous drying of chemical granules and particulate materials, Longxin's high-efficiency fluidized bed dryer features a multichamber, segmented structure. Temperature and airflow can be adjusted independently in each chamber to match the drying profile of different materials.

• Uniform fluidization: An integrated stirring and lump-breaking mechanism helps prevent agglomeration and channeling, supporting stable material fluidization.
• Improved heat transfer: High-efficiency finned-tube heat exchangers enhance heat transfer performance.

Designed for solid-liquid separation, washing, and drying in active pharmaceutical ingredient (API) manufacturing and fine chemical intermediate production, Longxin's integrated system combines a crystallization tank, a conical filtration and washing unit, and a single-cone vacuum dryer.

The configuration addresses several limitations associated with conventional integrated filtration, washing, and drying equipment, including insufficient heat transfer, slow drying, low loading ratios, and filter blockage.

Conical filtration and washing unit

The system combines rapid filtration with high-efficiency washing. A spiral agitator lifts and redistributes material to control cake thickness, enabling faster solid-liquid separation. The rotating conical screw agitator thoroughly mixes the filter cake with washing liquid to improve washing efficiency.

Repeated washing, filtration, and in-vessel mixing can be performed before the final filtration and drying stages, helping improve impurity removal and process consistency.

Single-cone vacuum dryer

The single-cone vacuum dryer integrates vacuum evaporation, particle breakup, powder mixing, and drying. Its low-shear spiral agitator gently mixes materials at low rotational speeds, reducing energy consumption and helping protect sensitive products.

Internal heating within the spiral agitator increases the effective heat-transfer area, supporting efficient drying of heat-sensitive materials while helping prevent agglomeration and lump formation. A solvent condensation and recovery system, together with dust collection equipment, supports cleaner operation and solvent reuse.

The system is particularly suitable for toxic, contamination-sensitive, and high-purity materials requiring controlled solid-liquid separation and drying, including applications with stringent GMP requirements.

According to Longxin's technical data, the integrated configuration can shorten the vacuum drying stage, which may account for more than 60% of the total filtration, washing, and drying cycle in conventional processes.
