Why Vacuum Belt Drying is the Optimal Solution for Slurry Materials? | Shanghai Minjie

In industries handling slurry materials (e.g., pharmaceuticals, food extracts, ceramics), traditional drying methods like spray drying often fail due to clogging, thermal degradation, or poor solubility. Shanghai Minjie’s vacuum belt dryer (VBD) offers a breakthrough, preserving product quality while achieving uniform moisture removal.

[Key Advantages of Vacuum Belt Drying for Slurries]

1. Non-Clogging Processing
   Unlike spray drying machines, which struggle with high-viscosity slurries, our vacuum belt drying system transports materials continuously on a heated belt under low-pressure conditions, preventing nozzle blockages and uneven particle formation.

2. Low-Temperature Drying
   Operates at 40–80°C (vs. 150–200°C in spray dryers), ideal for heat-sensitive compounds like plant extracts, probiotics, or polymer gels.

3. High Retention of Active Ingredients
   Vacuum environment minimizes oxidation, preserving bioactive compounds, flavors, and colors—critical for nutraceutical drying and specialty chemicals.

• Step 1: Pumping slurry onto the temperature-controlled belt.

• Step 2: Gradual evaporation under vacuum, forming a porous dried layer.

• Step 3: Crumbling & collecting the final product with >99% solubility.
